Pirate Sentai Gokaiger

After attempting to use the J.A.K.Q. and Battle Fever J Ranger Keys on Gokaioh, the Gokai Galleon realize they can not take a short cut in mastering the Ranger Keys' power as Captain Marvelous sends Joe and Ahim to pick up some food. However, the two stop in response to the Action Commander Zodomas, whose swordsmanship attracts Joe's attention and fights him as the Gokaigers battle the Gormin. However, the Action Commander overpowers Gokai Blue and takes his leave as the other Gokaigers arrive. While the others eat, Joe proceeds to hone his fighting style to counter Zodomas's fighting style with Ahim forced to watch before Joe tells her. As Luka tells Ahim to accept his reasons out of friendship, Joe completes his training. The next day, Joe finds Ahim waiting for him and as she gives him her Gokai Saber to use in his upcoming duel with Zodomas. However, Zodomas uses Zugormin to as Gokai Pink arrives to his aid before the other Gokaigers arrive. After the others assume the forms of the Gekirangers and Dekarangers to take out the Zugormin, they give their Gokai Sabers so Gokai Blue he can use a five-blade fighting style to defeat with his Five-Blade Style Blue Slash. When Zodomas and the Zugormin are enlarged, the Gokaigers form Magi Gokaioh to ground Zodomas before destroying him. Soon after, Joe presents a "thank you" cake to the crew and is modest about it

When the evil Space Empire Zangyack invades Earth, the 34 Super Sentai engage them in the Legend War before sacrificing their powers to destroy the armada. Some time after, the Gokai Galleon arrives to Earth with its crew of pirates after their navigation robot Navi confirms it to be where the Greatest Treasure in the Universe is buried. Though a small advance fleet of Zangyack ships are seen heading towards the planet, the Gokai Galleon's Captain Marvelous refuses to turn the ship around when they are close to the treasure. With that in mind, the Gokai Galleon fights through the fleet before forming Gokaioh to destroy them single handedly. After reaching the Earth, Captain Marvelous introduces himself and his crew to a group of humans as the Kaizoku Sentai Gokaiger and state their intentions to obtain the Treasure from them, only for no one to have no knowledge of the treasure. As Captain Marvelous has his lookout Luka Millfy sell her ring off for cash to eat at the Snack Safari, the Zangyack flagship Gigant Horse arrives within Earth's atmosphere as an infuriated Commandant Waruzu Giru declares an all-out assault on the planet with the main invasion force. Action Commander Shikabanen leads the Gormin Sailors to attack as the Gokai Galleon crew were about to eat. Though they attempt to stay out of the skirmish, the Gokai Galleon crew reconsiders due to their experience with the Zangyack forces conquering their planet long ago. Arriving to the aid of two women and several children, the crew transforms into the Gokaigers to battle the Zangyack forces. When the second wave arrives, the Gokaigers assume the forms of the Gorengers, Shinkengers and Magirangers to get rid of the Gormin. Transforming back, the Gokaigers use their Gokai Sabres' Final Wave attack to destroy Shikabanen. Soon after, now expecting retaliation from the Zangyack forces, the crew take their leave while being admired by the populace as heroes, though Captain Marvelous insists that they were not protecting them and only attacked the villains for ruining his lunch.

On the Gokai Galleon, after seeing more of the Zangyack Empire's invasion of the Earth, Captain Marvelous has Navi use its abilities to find a clue that the Greatest Treasure can be reached by asking someone dressed in black. While searching to no avail, they come across a student in a black school uniform who claims to know where the Treasure is. The boy talks about the Super Sentai that the Gokaigers became in their earlier battle, with Captain Marvelous revealing that their power comes from the Ranger Keys. The boy asks to take a picture of the captain with his Ranger Key in order to steal it, only to fail and run away after revealing he lied about knowing about the Treasure. However, Captain Marvelous realizes that the boy swiped his Shinken Red Key during the fight and goes after him with Ahim following to keep him from doing anything wrong. Through Captain Marvelous finds him, the boy refuses to give up the only protection Earth has since the Super Sentai teams disappeared, revealing that his grandfather died in the first Zangyack invasion during the Legend War. This makes Captain Marvelous remember his planet being invaded by the Zangyack Empire and being saved by a warrior dressed only in red who gave him the Ranger Keys and Navi, directing him to find the Greatest Treasure in the Universe. The Zangyack Empire's invasion forces resume their attack under Action Commander Bongan. Giving the boy his Mobirate, Captain Marvelous stands by as he transforms into Shinken Red and fights the Gormin as the rest of the Gokai Galleon crew arrives. But when Bongan overpowers the student, Captain Marvelous takes back his things before asking the boy if the planet had actual value. Liking the boy's answer, Captain Marvelous and his crew confront the Action Commander and take out the soldiers. Assuming the forms of the Dekarangers and then of the Hurricaneger and Gouraiger ninja teams, the Gokaigers assume the forms of Shinken Red, Gao Red, Magi Red, Gosei Red, and Geki Red to defeat him. However, Development Technical Officer Insarn uses her new invention to revive Bongan and enlarge him and three Zugormin to giant sizes. Gokai Red calls in the Gokai Galleon and launches the four Gokai Machines to take out two of the Zugormin. The Gokaigers then combine their Gokai Machines to form Gokaioh, taking out both the last Zugormin and Bongan with the student watching. Soon after, the Gokai Gallon sets sail with the rest of the crew unsure about their captain's reasons along with Navi's clue being apparently a fluke. However, the prophesied man in black, bearing the crest of Magitopia on his robes, watches them sail off into the sunset.

Sailing into the fog-ridden forest, with their radar failing on them suddenly and Navi blamed for this course, the Gokai Galleon engages a Zangyack battleship in combat before crashing. Don "Doc" Dogoier panics as he suggests they should leave quickly before they are attacked by the battleship's captain, Action Commander Salamandam, who has been sent to Earth to cause mass volcanic eruptions. The Gokaigers battle Salamandam and the Gormin before the Action Commander uses his tail's eruption-invoking powers to separate Captain Marvelous and Doc from the others. The two then meet the mysterious figure in black, the Red Magician Kai Ozu who points out the Gokai Galleon crew has yet to use the Ranger Keys' true power. Kai tells them that if they follow him without transforming, he will give them information about the Greatest Treasure in the Universe, using his magic and Heavenly Saint Flagel to hinder them along the way. Though Doc is fearful of the obstacles set up against them, Captain Marvelous manages to bravely overcome Kai's magic. Meanwhile, the other Gokaigers assume the forms of Abare Black, Ninja Black, and Go-on Black to take out the Gormin. But when Salamandam arrives, the three take on the forms of Big One, Gao White, and White Swan to drive the Action Commander back, causing him to interfere in Captain Marvelous's literal leap of faith to pass Kai's final test. Though frightened to jump to reach Kai, Doc overcomes his fears in order to save his captain's life from a loose boulder while barely making it to the other side. After explaining to Doc how it was courage that gave him and his family the power to fight Infershia many years ago, Kai reveals that Doc has passed his test to see if his courage can release that same power in the Magiranger Keys. After revealing the Gokai Galleon crew will obtain the Greatest Treasure by mastering the power of all thirty-four Super Sentai, Kai takes his leave as the other Gokaigers arrive when Salamandam emerges again. The Gokaigers proceed, assuming the forms of the Magirangers to fight him. Doc's courage in the face of danger enables them to perform the binding "Magi Magi Go Gokai" spell to hold the Action Commander at bay while they use the Ozu siblings' signature final attacks to defeat Salamandam along with their own Gokai Blast Final Wave attack. When Salamandam and the Zugormin enlarge, Gokaioh is overpowered by the four opponents before the Magiranger Keys react to the situation. Using them, the Gokaigers summon Magi Dragon from within Gokaioh, turning the giant robot into Magi Gokaioh which takes out the Zugormin with its new powers before performing the Gokai Magi Bind finishing attack to destroy Salamandam. With Kai seeing Flagel off to Magitopia, he sees his power is in the right hands as he takes his leave. On the Gokai Galleon, the crew apologizes to Navi for doubting his fortune, before accidentally upsetting the robot parrot once more.

After the Gokai Galleon crew discover via the latest intergalactic newspaper that their bounties have skyrocketed to 6,751,000 Zagin, with their captain not fazed by it, Navi's latest fortune tells them to look towards police for their next clue to obtain the Greatest Treasure. However, upon arriving to the nearest station while the others questioned if it's wise for them to enter, Captain Marvelous goes in and finds himself handcuffed by Officer Marika "Jasmine" Reimon of the SPD, who has been circulating wanted posters at the station and arrests him on the charge of piracy. While the others escape to the Gokai Galleon on his orders, Captain Marvelous manages to outrun the police before finding himself pursued by SPD chief Doggie Kruger, who easily defeats the pirate and confiscates his Mobirate. Before Kruger brings Captain Marvelous in, they accidentally stumble into a Zangyack scheme overseen by the Alienizer Buramudo to launch Subterranean Missiles to destroy every city on Earth in two hours. When their presence is discovered, Kruger is wounded as he manages to get Captain Marvelous out of harm's way. Though Captain Marvelous offers to help him, Kruger refuses to trust the pirate as he leaves him behind to stop the missile launch regardless of his injuries. Realizing how injured his captor is, Captain Marvelous saves the alien from the potential suicide mission and takes him to safety. With Captain Marvelous's sense of honor against all odds winning his trust, Kruger uncuffs the pirate and hands him back his Mobirate. Meanwhile, on their search for their captain, the other Gokaigers battle several Gormin and Zugormin units and defeat them by changing into the Go-ongers and Dairangers. By nightfall, Gokai Red rushes in and destroys the missile launching device in time before reuniting with his crew. Together, they change into the Dekarangers and defeat Buramudo. When Buramudo is enlarged, Gokaioh is formed to stop him from manually launching one of the Subterranean Missiles, taking out some of the Zangyack fleet in the process. Kruger tells the Gokaigers they can now summon the powers of the Dekarangers. Using the Dekaranger keys, they summon the Pat Striker from within Gokaioh. The Pat Striker drives around Buramudo and fires a barrage of lasers at him before returning to Gokaioh to reform Deka Gokaioh. Both Deka Gokaioh and Buramudo engage in an intense gun fight until Deka Gokaioh finishes off Buramudo with the Gokai Full Blast. The next morning, the Gokaigers escort a wounded Kruger when they are cornered by a police barricade. However, Officer Banban "Ban" Akaza suddenly appears and notifies the alleged acts of piracy by the Gokaigers were proven to be a hoax instigated by the Zangyack Empire. Though the pirates are free to go as he takes Kruger, Ban warns Captain Marvelous not to abuse the Dekarangers' powers with a promise of personally hunting him down with less mercy as Kruger shown to the pirate

While at a jewelry store with Doc, Luka encounters a spoiled girl named Komaki Kasugai who buys everything in the jewelry store, including a ring she had her eye on, much to the dismay of her tycoon father Kozo Kasugai. After Luka complains about Komaki's spending spree and stating her notion of money, Kozo offers her a job as a maid with the ring she wanted as payment. At the mansion, he shows her all of the priceless antiques on display, including his most prized, heavily-guarded possession: a gold tree. However, to Luka's dismay, she to look after Komaki, thrown out of her room after seeing a tattered rabbit doll and tossing it into a waste basket. Later, Luka tells the Gokai Galleon crew about the Kasugais and their unusual attitude toward money, learning that that Kozo was a peniless man until discovered a strange meteorite which held the gold tree. Meanwhile, the Zangyack Empire sends Action Commander Nanonanoda to Earth to steal the gold tree to fund their invasion. Nanonanoda enters the mansion and managed to bypass the security system until Luka notice Komaki watching him, causing the Action Commander to accidentally activate the system and forced to run out. Outside the mansion, attacking him upon learning he is the tree's owner, Luka makes a deal with Kozo to get rid of Nanonanoda for a million. Becoming Gokai Yellow, she assumes the forms of Vul Panther and Bouken Yellow to throw the Action Commander out of the premises. Later, Luka confronts Komaki on why she did not alert her father on the intrusion, only to learn from Komaki that she and her father would be better off without the gold tree and went on her spending spree to get them back to that time. This fact infuriates Luka as lectures Komaki that money makes the world go round. That night, after remembering her own past, Luka is approached by Joe who asks for talk about how she needs money to fulfill a life-long dream. The next morning, Nanonanoda invades the mansion with a platoon of Gormin, setting the complex on fire without realizing he would harm the tree. The Gokaigers intervene, having Luka see to the Kasugais while the others assuming the forms of the J.A.K.Q. Dengekitai and quickly dispatch the Gormin before battering Nanonanoda with the J.A.K.Q. Hurricane. Luka finds the father and daughter and tells them to leave the burning mansion immediately, but Komaki hesitates - saying she does not want to leave something important. Given a check for 10 million yen by Kozo to retrieve the gold tree, Luka tells Komaki she will bring back the prized possession. As the Kasugais leave, Luka changes into Go Yellow to obtain her quarry before emerging from the burning mansion, having retrieved not the gold tree but Komaki's rabbit doll instead. Kozo discovers that his daughter has held onto it for a long time and realizes that his wealth had distanced him away from her. As the gold tree melts from the fire, Kozo apologizes to his daughter and agrees with her to start over again. Not being good at situations like this, Luka changes into Yellow Racer and joins the others as they eliminate Nanonanoda with the Final Wave from their Gokai Sabers. When Insarn enlarges Nanonanoda, Deka Gokaioh is formed to easily destroy the airborne Action Commander with the Gokai Full Blast. As the Kasugais watch the battle, Komaki discovers that Luka returned the check inside the doll. Later, the Gokai Galleon crew commend Luka for her generosity, with Joe mentioning that she practically worked for free. Luka then reveals to them that she was paid, in the ring she wanted earlier.

With the next clue from Navi saying that they need to find the tiger child, the Gokaigers search to no avail before their search is interrupted by Cosmic Kenp? Master Pachacamac XIII. Furious of the interference, the Gokaigers fight Pachacamac yet Ahim and Doc are outmatched by Pachacamac's Cosmic Kenp? fighting style with the others assume the forms of the Gao Red, Gao Yellow, and Gao Blue to drive him off. Later, talking over their level of skill in fight, Ahim and Doc come across Geki J? Tiger-Ken master Jyan Kandou with the former wanting to train along with the children that Jyan's teaching while Doc chickens out. That night, after Navi explains to the crew that they jump to the wrong conclusion by going after a tabby and later realize that they trained themselves, Doc resolves to get strong as Captain Marvelous and Luka. The next day, Doc joins Jyan's class to Ahim's surprise while the rest of the Gokai Galleon crew battles Pachacamac using the power of the Sun Vulcan team. However, Pachacamac uses a new technique thanks to Insarn's modifications. When contacted by Navi about their crewmen in trouble, Ahim and Doc learn from Jyan that their training is over as he reveals himself as the tiger child they are looking for. Arriving at the battle, Gokai Green and Gokai Pink tell the others to use the Gekiranger Keys to counter Pachacamac, weakening him before using the Gokai Blast Final Wave to finish him off. When Pachacamac enlarges, Gokaioh is formed to fight him using the Gekiranger Keys to summon Qi-based images of the Geki Beasts to destroy the villain. Elsewhere, as Doc is now able to stand up for himself, Jyan tells Master Xia Fu that he will entrust the future of the planet to the Gokaigers.

After Magi Gokaioh finishes off the Zugormin sent to Earth, Warzu Giru snaps and takes out his frustration on his subordinates before he and Barizorg leave to find an Action Commander for the next invasion. But more concerned of the Gokaigers' ability to use the powers of the Super Sentai, with Insarn giving him review on the Gokai Galleon crew save Doc, whom is of no concern, Damarasu sends the Sneak Brothers - Elder and Younger - to learn more of their enemies' goals while keeping Warzu Giru in the dark of their activities. After multiple failures, Elder manages to stow away on the Gokai Galleon and overhears the crew talking about the Greatest Treasure before being forced into a series of madcap attempts to hide when the crew notices Navi is missing and they go searching for him. After searching the ship from top to bottom, the crew pins the blame on Doc for Navi's disappearance before the robot parrot returns from the beach. After the crew ties him up for worrying them, Navi proceeds to give them their next clue: an island in the sky. Elder then reveals himself to the crew and gloats how knowing their intentions as Joe uses a baseball bat to swat him out of the ship. Younger frets over his brother's well being as the crew descends to take out the Gormin Soldiers with the powers of the Gaorangers and the Denzimen. The Gokaigers then use the Goggle V Keys to tie up Younger and toss him around before finishing both brothers with their Gokai Sabres' Final Wave. Enlarged by Insarn, the Sneak Brothers face Gokaioh. However, Elder is batted away to oblivion with the Gokai Bat as Younger attempts to avenge his big brother before being destroyed by Deka Gokaioh. Though Insarn fumes over the loss of her favorite minions, Damarasu knows the Gokai Galleon crew's goal as the pirates proceed to sail off to find the island before the Zangyack forces do.

With no luck in finding a flying island before the Zangyack forces, the Gokai Galleon crew find Sky Island Animarium. However, upon setting foot on Animarium, the Gokai Galleon crew are attacked by a Gormin platoon under Action Commander Bauza. Eventually, after the Gokaigers use the Turboranger Keys to win against Bauza's speed, the conflict attracts the attention of Gao Lion who proceeds to knock everyone off the island. The Gokaigers use the Jetman Keys to break their fall as Bauza rides a Sugmorin and manages to wound Ahim. The crew are about to get back up to Animarium to catch Gao Lion, realizing him to be the power they are looking for, when they are warned by Kakeru Shishi that they will not gain the Power Animal's power, with Captain Marvelous, Luka, and Joe refusing to take heed. Tending to Ahim's wounds in his office, Kakeru reveals himself as Gao Red with Doc pleading for Gao Lion, only to explains that only the Power Animal can make that call. Ahim and Doc proceed to defend Marvelous, Joe, and Luka by revealing that the three are looking for more than treasure before they are contacted that their crew mates are fighting Bauza and the Gormin. Kakeru watches the Gokaigers' fight and is astonished by Gokai Red, Gokai Blue, and Gokai Yellow save people in their own rough way before they, Gokai Green, and Gokai Pink use the Gaoranger Keys to defeat the Zugormin with the Hyakujuuken before finishing Bauza with the Gokai Blast. When Bauza and the Zugormin are enlarged, Gokaioh's Gokai Star Burst is disabled. However, Gao Lion's acceptance enables them to summon him from Animarium with the Gaoranger Keys as he and Gokiaoh combine into Gao Gaokaioh to take out the Zugormin before destroying Bauza. As Kakeru walks off after wishing Gao Lion good luck with his new partners, the pirates thank their new ally as they sail off.

While playing a game of poker, with Captain Marvelous losing several hands while Joe gets a winning streak thanks to Luka holding back, the Gokai Galleon crew are alerted of a Zangyack fleet. Magi Gokaioh subdues fleet but the green one commanding the fleet as Gokai Blue's insistance. After the fleet retreats, Joe explains to the crew that the green ship is the flagship of Zangyack's "Special Destruction Unit", as it uses a cannon that uses ammo made of Gigalorium - a rare material capable of destroying planets with a single shot; destroying the ship would have caused the Gigalorium aboard to explode and scorch the Earth's surface. Luka then suggests that she and Joe will infiltrate the ship and steal the Gigalorium. As the ship is docked over an abandoned mining field, Gokai Blue and Gokai Yellow use their color respective Boukenger Keys to sneak under and board it. Inside, Joe and Luka disguise themselves as Gormin and make their way to the ship's armory where the Gigalorium is. However, they are taken to a break room by two Zugormin to play a game of poker. Luka offers to play against both Zugormin, using her sleeve trick to cheat her way. The games that follow attract every Gormin on the ship before the game is suddenly stopped by ship's captain Yokubarido when he exposes Luka's cheating and then her and Joe's disguises. However, as a gambler with respect in their guts stowing away on his ship, Yokubarido offers to let them go if they can beat him in a game. If they lose, they must surrender for him to collect their bounty. With the Action Commander using own deck, Joe offers to accept his challenge in place of Luka despite the disadvantages piled against him. Yokubarido shows a four of a kind, but Joe miraculously beats him with a royal flush. Refusing to accept that he lost, Yokubarido orders his troops to kill Joe and Luka when the rest of the crew arrive in Gormin guises. It is revealed that the card game was a planned diversion to have the trio sneak into the armory and steal the Gigalorium. Gokai Green then sets off an explosive to sink Yokubarido's ship as he and surviving troops are forced to watch the Gigalorium capsule being taken by Navi to the Gokai Galleon. After disposing of the Gormin, the Gokaigers use the J.A.K.Q. Dengekitai Keys to take out the Zugormin officers with the Big Bomber attack before using Final Wave attacks on Yokubarido. After being enlarged by Insarn, Yokubarido uses his explosive card attack on Gokaioh before the robot presents Gigalorium. Intending to return it, the Gokaigers have Gokaioh throw it into space towards the Zangyack fleet, taking out more of the ships in the process, before forming Gao Gokaioh to finish Yokubarido. Later, as the Gokaigers play another game of poker, Joe discovers that Luka switched decks to ensure his win against Yokubarido, much to his dismay.

While Joe is practicing his swordsmanship with Ahim and Doc watching, they are notified of yet another Zangyack invasion. After Gokaioh takes out the Zugormin with the Dekaranger and Magiranger Keys, Captain Marvelous gets a clue from Navi to beware of a "sa-mu-r-ai". While they think on the clue, the Gokai Galleon crew find a kendo class at a park with Joe remembering his days in the Zangyack forces military and his senior Sid Bamick. Then, all of a sudden, a group of Kuroko with white banners appear and the Gokaigers are introduced to Kaoru Shiba, who demands the Shinkenger Ranger Keys from them. After Captain Marvelous refuses, she grabs her Shinkenmaru katana and attacks him. He dodges her attacks and is about to pull his Gokai Gun on her, but Ahim intervenes and tells him not to shoot Kaoru while Doc tells him she might know the secret to unlocking the Shinkenger keys. Joe then steps in and issues a challenge to the female samurai. Meanwhile, after making a fuss of the latest defeat, Warzu Giru is paid a visit by his father's bodyguard Deratsueiger, whose presence makes him confident to the point of personally overseeing the intermediate attack. The duel between Joe and Kaoru is interrupted by a Zangyack invasion as the latter cuts down every Gormin Sailor on her path, before a Zangyack army led by Warzu Giru, Barizorg, and Deratsueiger beams down to the scene. Warzu Giru demands everyone to bow before him as the Gokaigers arrive to actively defy him. The Gokaigers eliminate the Gormin Sailors and Zugormin units, but are unable to harm Deratsueiger with the powers of the Zyurangers and Dynamen. Deciding to go after Warzu Giru, the Gokaigers change into the Gingamen to hold Deratsueiger while Gokai Blue (as Ginga Blue) charges toward the Zangyack forces leader. However, Barizorg forces him to change back into Gokai Blue form and a sword fight ensues before Gokai Blue recognizes Barizorg's fighting stance as that of Sid's. After being pummeled by Barizorg's attack, Joe asks him if he is Sid; in response, Barizorg does not know him. Warzu Giru then reveals to Joe that the Sid he knew was converted into the cyborg Barizorg for treason as his swordsmanship was too valuable to waste. Joe stands in disbelief as Barizorg approaches him to slash him, but Gokai Red rushes to block the attack - receiving the blow to the back. With the last of his strength before passing out, Captain Marvelous then fires at Barizorg, throwing his sword out of his hand with a stray shot hitting Warzu Giru's left arm, forcing Barizorg and Deratsueiger to retreat to get their leader away from harm. Due to the heroism displayed by Captain Marvelous, Kaoru offers to have her Kuroko treat his wounds aboard the Gokai Galleon. Feeling the guilt over getting Captain Marvelous injured, Joe climbs up the crow's nest of the ship, thinking about his former comrade and what he has become. As the other Gokaigers gather to sleep around Captain Marvelous, Kaoru's retainer Toshizo Tanba tells her that the Ranger Keys are stored in the treasure chest with Navi sitting on it and tells her now is a good opportunity to take the Shinkenger Keys. She hits him with her fan in response and tells him she wants to continue observing the Gokaigers. The next morning, Luka notifies everyone that Joe is missing and he has left them a note, telling everyone that there is a matter he needs to settle alone.

When Joe mysterious leaves, the others worry about him as Captain Marvelous tells them to leave him be as he is confident that he will return. Remembering the events that led to him leaving the Zangyack forces and Sid, Joe finds Barizorg's sword as the cyborg arrives to reclaim his weapon. Though he heard the truth about his origins, Barizorg refuses to accept it and defeats Joe before taking his leave as the pirate sees his friend is truly dead. Aboard the Gokai Galleon, Kaoru learns how Joe became a pirate before Deratsueiger returns to Earth to carry on Warzu Giru's orders to slaughter the Gokaigers for hurting him. Though Kaoru offers to help, Marvelous turns her down as he and the others fight the Gormin and Zugormin with the power of various Sentai warriors before Deratsueiger defeats them. After having an realization, Joe arrives to help after Kaoru gives him a Secret Disc to even the odds. The gathered team assume the forms of the Shinkenger to battle Deratsueiger, with Shinken Blue using the Secret Disc to fight with two Shinkenmaru before the pirates finish Deratsueiger off with Gokai Slash. Enlarged, Deratsueiger proceeds to destroy the city before overpowering Gao Gokaioh. However, using the Shinkenger Keys, Gao Gokaioh reforms into Shinken Gokaioh. After taking down an entire platoon of Zugormin, Shinken Gokaioh destroys Deratsueiger. Later, the crew's captain collapses from starvation as everyone else carries him to a place to eat while Joe says it is good to be home under his breath.

Fully recovered from the Shinkenger incident, Captain Marvelous notices that Ahim is missing as the others tell him she is walking around in the city below. While in a marketplace, she is kidnapped at gunpoint by a man named Eikichi Nashida, who tries to hold her ransom. But after she promptly disarms him of the toy gun he is carrying and reveals herself to be a space pirate, Nashida begs forgiveness as he confesses to her that he needs the money to pay back a mobster. Hoping to help him, she calls her shipmates and unknowingly makes them think she is kidnapped. Attempting to clear up the incident, Nashida finds himself listening to Captain Marvelous's death threat for taking one of his crew. Suddenly, Ahim and Nashida are confronted by Action Commander Zaggai, who is tracking down Poisole - a special metal which produces a neurotoxin once charged with electricity. Ahim gets Nashida - who apparently has the Poisole on him - to safety as the Gokai Galleon crew come in guns blazing and find Ahim's necklace, with Navi's Zangyack detection having them jump to the conclusion that they are behind the kidnapping. After briefly evading Zaggai, and confirming the Poisole on his person, Ahim assures Nashida he is not a loser as she points out he saved Earth's people compared to her outliving her own and taking a new path. Zaggai arrives by then with the Gormin as the other Gokaigers appear soon after. After Zaggai attempts to explain to her crew mates that he is not a kidnapper, Gokai Pink leads her crew into battle with Nashida understanding her words of finding a new path to take. Using the powers of the Gingamen, the Gokaigers brutalize Zaggai before finishing him off with the Gokai Blast with Gokai Pink apologizing for not coming clean prior to Gokaioh battling the enlarged Action Commander. Using the Ranger Keys, Gokaioh changes into Deka Gokaioh to knock Zaggai off balance before forming Shinken Gokaioh to finish him off. After the fight, with the Poisole thrown into the sea to be neutralized by the salt water, Ahim wishes Nashida the best of luck and tells him to call her if he needs any help.

Aboard the Gokai Galleon, the crew is taking a nap when Navi's dream triggers a new clue for the pirates, telling them to learn traffic laws. Meanwhile, while reviewing Zaggai's activities aboard the Gigant Horse, Insarn falls in love with a man that the Action Commander crossed paths with: Kyousuke Jinnai. Wanting Kyousuke, Insarn asks Action Commander Jerashid to capture him, unaware that Jerashid has been in love with her since high school. Finding Kyousuke at a park after failing to impress the children he was entertaining, Jerashid and his Gormin Sailors attempt to capture him when the Gokai Galleon crew witness it during their search. Using the powers of the Zyurangers, the Gokaigers force Jerashid to retreat. After the fight, Kyousuke hands each of the Gokai Gallon crew a drink and introduces himself as the former Red Racer of the Gekisou Sentai Carranger team; after the Legendary Great War, he has become an actor struggling to educate children on traffic safety. After hearing the pirates' need to master the Carranger Keys' full power, Kyousuke agrees if they join his traffic safety acting troupe. The Gokaigers decline and run away to find another Carranger member, with Kyousuke pursuing them with his lighting-quick running speed. By then, after realizing that Insarn in love with Kyousuke, Jerashid returns to Earth to eliminate the Carranger with extreme prejudice. However, Insarn intervenes and spirits Kyousuke away, leaving the Gokaigers confused if the Carrangers are really that powerful until Insarn tells them to transform. Using the power of the Carrangers - at Kyousuke's insistence, the Gokaigers counter Jerashid's fire-based attacks with the unorthodox Gokai Kurumagic Attack while Kyousuke tries to distance himself from the love-crazy Insarn. Watching the entire fight, Warzu Giru uses the enlarging gun on Jerashid to put an end to the madness. Despite Kyousuke's attempt to help him successfully express his feelings to Insarn and receive her's in return, Jerashid lets out his happiness by destroying the city until Gokaioh is formed to fight him. Using the Gokai Radical Racing Slash to weaken Jerashid, Shinken Gokaioh is formed to knock the Action Commander into the Gigant Horse. Though he survives the Gokai Samurai Slash, Jerashid loses Insarn's respect as she requests him to be launched into deep space with the garbage. Soon after, the Gokaigers are forced by their need to obtain the Carranger Keys' powers to act in Kyousuke's traffic safety show. As Kyousuke joins in, Navi watches from the Gokai Galleon's monitor before turning it off, saying that not all Legend powers are useful as she takes a nap.

Doc shows his shipmates that the Gokaigers' bounties have skyrocketed to nearly the same level of the Red Pirates. Showing no interest in the news, Captain Marvelous tells Navi to foretell their next course; the robot parrot, however, sees danger coming their way. Meanwhile, a red Zangyack ship arrives to the Earth with Warzu Giru learning that it is captained by a privateer under the Zangyack Empire. While cautiously exploring in a town, the Gokaigers meet the privateer, who Captain Marvelous identifies as Basco ta Jolokia. He announces that he has also come for the Greatest Treasure in the Universe. To everyone's shock, Captain Marvelous tries to attack Basco before three giant Zugormin units appear on orders from Damarasu - who sent them to show the privateer the capabilities of the Gokaigers. Forced to let Basco go, a hesitant Captain Marvelous summons Gokai Galleon before Gokaioh is formed to dispatch the Zugormin soldiers while Basco watches. After the fight, Captain Marvelous is reluctant to talk about his past with Basco, but his shipmates learn that Basco was also a Red Pirate himself. Both Captain Marvelous and Basco served under Aka Red aboard the Gokai Galleon, as they collected Super Sentai powers that were scattered across the galaxy and contained them in Ranger Keys. Then, one day, Basco betrayed his comrades by selling them out to the Zangyack Empire so he can have the Ranger Keys all to himself, which led to the downfall of the Red Pirates and Captain Marvelous getting the Ranger Keys. Captain Marvelous then receives a call by Basco, from his golden Mobirate, for them to settle their differences with a duel. When they meet up, Basco reveals that he has obtained Ranger Keys of Sentai heroes that Aka Red failed to mention to either of them. Using a trumpet, Basco summons Dragon Ranger, King Ranger, Time Fire, Shurikenger, and Deka Break to have them gang up on Captain Marvelous. However, though Captain Marvelous insisted that they not interfere, his crew arrives to even the odds. Though the Gokaigers manage to defeat the sixth hero Sentai warriors in one-on-one duels and return them to their original Ranger Key forms, the tables are turned in Basco's favor when he overpowers the pirates with Kiba Ranger, Mega Silver, Gao Silver, Abare Killer, Magi Shine, Bouken Silver, Go-on Gold and Silver, Shinken Gold and Gosei Knight. With his crew brutally beaten without mercy, Captain Marvelous realizes they are Basco's actual targets and he is powerless to save them. He is left with the Ranger Keys of the five warriors that were defeated as Basco takes his shipmates captive.

Unable to track his crew and the Free Joker, Captain Marvelous gets frustrated before he gets a call from Basco. Assuring him that they are right, Basco offers Captain Marvelous to trade the Ranger Key chest, the Gokai Galleon and Navi for his crew, or he will hand them over to the Zangyack for the bounty. Taken to the Free Joker's brig by Sally, who has their Mobirates, the crew attempt to escape through the ducts. However, Basco was a step ahead of them and placed them back into their cell. As that occurs, after remembering the events that led to him joining the Red Pirates, Captain Marvelous regains his confidence and calls Basco to arrange an exchange meeting with his crew present. Though he brought the Ranger Key chest, Captain Marvelous has no intention of doing the trade as he suddenly throws the treasure chest in the air while he fights Basco, spilling all of the keys and his own Mobirate in time for Doc to catch it with his mouth and using Shinken Green Key to free himself and his shipmates before getting their Mobirates back from Sally. Basco then unleashes his 10 Super Sentai warriors and the Gokai Galleon crew assume their Gokaiger forms to battle them while Navi gathers the Ranger Keys back into the chest and takes them back to the ship. Defeating Mega Silver, Gao Silver, Abare Killer, Bouken Silver, and Shinken Gold, the Gokaigers use the Final Wave to take out Kiba Ranger, Magi Shine, the Go-on Wings, and Gosei Knight. Deciding to take his leave, Basco leaves the Liquidroid Wateru behind to fight the Gokaigers as they use Shinken Gokaioh to destroy the monster. Back aboard the Gokai Galleon, the Gokaigers look at the 15 newly-acquired Ranger Keys as they assure their captain that they have no hard feelings for what happened. On the Free Joker, impressed by his old friend's move, Basco reveals that he has 10 more Ranger Keys in his possession.

After finishing a fight against the Zugormin with the recently acquired greater power of the Goseiger Keys, the Gokai Galleon crew marvel about obtaining both the ten other greater powers and the 15 extra Ranger Keys from Basco as they receive a new clue from Navi to find a man in silver. Starting their search at a park, after hitting a dead end with an overweight jogger wearing a silver track suit, the crew meets a Super Sentai fanboy before running into Action Commander Arumadon and a Gormin platoon, who were sent there to plant a bomb. The Gokaigers quickly dispose of the Gormin and the bomb before transforming into Time Fire, Magi Shine, Mega Silver, Dragon Ranger and Abare Killer to fight Arumadon with the fan boy watching. Arumadon overwhelms the Gokaigers with his Aruma Barrier before Gokai Green (as Dragon Ranger) uses his Zyusouken to damage his collar and the Action Commander retreats right when the fan boy is about to join the fight. Soon after, the crew are confronted by the fan boy, introducing himself as Gai Ikari. After shooting down Gai's offer to join their group as the sixth Gokaiger and improve their public image, the Gokai Galleon crew gets an earful from Navi for forgetting their search. Upon reaching another dead end with the overweight jogger, the crew are attacked by Arumadon. However, Gai suddenly arrives and tells the Gokaigers to let him handle the villains as he changes into Gokai Silver. The Gokaigers are shocked to see an Earthling possess a Ranger Key while Gokai Silver tries to win membership by dispatching a group of Gormin single-handedly with his Gokai Spear. But when Gokai Silver is unable to break through Arumadon's barrier, the Gokaigers take over to target the weak spot on Arumadon's collar. However, unknown to both the Gokaigers and even Arumadon himself, Warzu Giru had Insarn had secretly modified the Action Commander's collar to turn him into a suicide bomber to take out the pirates. Luckily, Gokai Silver realizes the trap and safely detonates the bomb before destroying the shocked Arumadon with the Gokai Shooting Star Final Wave. Realizing that Gai is the silvery man they are looking for, the Gokai Galleon crew are curious to know how he obtained his power.

When the Gokai Galleon crew learns that he has three greater powers, they take Gai to their ship where he reveals his origins. Days ago, after being hospitalized from risking his life to save a girl from a truck, Gai is visited in his dream by the ghosts of Dragon Ranger, Time Fire and Abare Killer - the latter changing into Mikoto Nakadai as he gives Gai the Gokai Cellular and Gokai Silver Ranger Key. However, after Gai reveals that he is yet about to activate the greater powers, he is allowed by Captain Marvelous to search the chest for the Time Fire, Dragon Ranger, and Abare Killer Keys. Once the keys are found, Captain Marvelous confiscates them, the Gokai Cellular, and the Gokai Silver Key from Gai. But seeing Gai determined to fight, though not realizing the disadvantage of becoming a wanted man, Marvelous asks him if he has anything to offer him like the rest of his crew. The next day, while thinking of what use he can be to the crew, Gai responds to a Zangyack attack led by Action Commander Osogain at a construction yard. Despite not being able to change into Gokai Silver, Gai fights a losing battle until the Gokai Galleon crew arrives. Seeing his unrelenting courage and determination against all odds, Captain Marvelous hands Gai his phone and key, officially making him a member of the crew after liking his answer to take out the Zangyack Empire. After finishing off the Gormin, despite a brief mix up with the King Ranger Key, the Gokaigers use the Shinkenger Keys to take out the Zugormin. The five main Gokaigers then change into different silver-colored warriors to weaken Osogain before Gokai Silver destroys him with the Gokai Supernova Final Wave. When Osogain and his Zugormon are enlarged, Gokai Silver uses the Time Fire Key to summon the Goujyu Drill time jet. Gokai Silver then proceeds to use the Dragon Ranger Key and then the Abare Killer Key to respectively convert his mecha into the dinosaur mode Goujyu Rex and then the robot mode Goujyujin to destroy the Zangyack forces with the greater powers of the three Sentai teams. Later aboard the Gokai Galleon, despite being a cabin boy, Gai looks forward to working with the Gokaigers as they prepare an all-night celebration.

After having his Gokai Buckle linked to the treasure chest's Key Road, Gai offers to make lunch while Doc is still unsure about the cabin boy. Thirty minutes later, everyone enjoys delicious food to Doc's dismay as he begins to become more insecure overtime. By then, the Action Commander Worian is sent by a reinvigorated Warzu Giru to fish out people's skeletons and leave them in a catatonic state. Seeing Worian, Gokai Green and Gokai Silver fight him and the Gormin with the former not having any luck before the others arrive. The Gokaigers assume the forms of the Go-ongers with Gokai Silver perplexed on which of the Go-on Wings he should be. After having a daydream involving Go-on Gold and Go-on Silver, Gokai Silver finds himself with a merged Ranger Key and uses it to become a hybridized Go-on Wings to engage Worian in battle when Gokai Green (as Go-on Green) begins to feel less confident. Suddenly, Worian fires a blast toward Gokai Green, and Gokai Pink (as Go-on Black) rushes to take the hit. Worian then debones the Gokaigers except Gokai Green and Gokai Silver before teleporting away. Back aboard the Gokai Galleon, after Doc that he admits he cannot stand being around him, Gai goes off on his own to track down Worian. Doc tells Navi he feels Gai is better than him in every way, but the robot parrot explains to him that Gai felt that Doc is the better man after merely looking at Doc's recipe book. Doc then has a change of heart, having an idea from remembering the hybridized Go-on Wings form before running to assist Gokai Silver. As Gokai Green assumes the forms of Green Two and Green Flash to hold off the Action Commander, he has Gokai Silver daydream to combine the 15 sixth hero Ranger Keys. The Ranger Keys comply and form the Gold Anchor Key. Using the Gold Anchor Key to assume Gold Mode, Gokai Silver quickly overwhelms Worian with his new abilities before finishing him off with the Gokai Legendream Final Wave; thus restoring everyone's skeleton much to Warzu Giru's dismay as he once again lapses into depression. Worian enlarges as Gokaioh and Goujyu Rex double-team the Action Commander before Goujyu Rex changes into Goujyujin to single handedly destroy him. While having dinner, Doc relapses in insecurity when he finds that a Z=100,000 bounty has been placed on Gai while his remains at Z=5,000.

Navi's latest clue to the treasure is to find a warrior in a sealed forest, which Gai quickly identifies as the Ginga Forest - home of the Gingamen. After Gai explains that the Gingamen protected Earth from a band of space pirates, Doc expresses worry while Gai admits he has no idea where the Ginga Forest actually is. Using Gai's copy of Haruhiko Aoyama's Book of Legends, the Gokai Galleon crew search for the entrance to the Ginga Forest and find themselves walking in circles before Hyuuga suddenly bursts out of the Ginga Forest's invisible barrier, followed by Basco and Sally. The Gokaigers tell Gai who Basco is, but he immediately recognizes Hyuuga. He introduces himself to the man before asking for his autograph. Basco then unleashes Deka Master, Wolzard Fire and Magi Mother to hold off the Gokaigers so he can capture Hyuuga as Gai takes him to a safer place. While Gokai Red is forced to fight Sally to get to Basco, the other Gokaigers are easily defeated by the extra warriors as they are thrown into a river. Fortunately, they are saved by Ryouma; Doc thanks him for saving them, despite not initially recognizing who he is, as he and the others search for Gai and their captain. Meanwhile, Gai tends to Hyuuga's wounds while talking about himself just being a novice compared to him and the past Super Sentai groups. Hyuuga then asks him to give him the Gokai Cellular so he can be able to protect the world again. Despite a long hesitation, Gai is about to give Hyuuga the Gokai Cellular when Basco appears, using his trumpet to siphon the greater power out of Hyuuga. Gokai Red intervenes to stop Basco, who then unleashes the Black Knight to battle him as the other three extra warriors arrive. Inspired by his captain's refusal to let go of his dream even if the odds are against him, Gai takes the Gokai Cellular before Hyuuga can grab it. However, as the rest of the Gokai Galleon crew arrives, Hyuuga reveals that he was testing Gai's self worth as a protector of the world. Gokai Silver enters Gold Mode to defeat the Black Knight with the Gokai Legendream Final Wave, with Hyuuga regaining the Black Knight Key, while the main five Gokaigers change into the Gingamen to weaken the other extra Sentai warriors. Though Deka Master, Wolzard Fire, and Magi Mother are eliminated by the Gokai Blast, their Ranger Keys are recovered by Sally as Basco unleashes the Moonroid Tsukki. Shinken Gokaioh and Goujyujin engage Tsukki and destroy it with a Gokai Samurai Slash and Goujyu Triple Drill Dream combination attack. Later, Hyuuga hands Gai the Black Knight Key and the Gingamen's greater power, telling him that the powers of the Super Sentai should be best gathered in one place. As the Gokai Galleon sails off, Ryouma arrives admitting his surprise that the newest Super Sentai team is a bunch of space pirates. Hyuuga asks if his hatred for space pirates is still strong, and Ryouma tells his elder brother that he thinks the Gokai Galleon crew are an exception and admits that he highly respects their friendship.

Still vexed by learning of Basco's ability to take greatest powers from past Sentai warriors, Captain Marvelous gets into a heated argument with Navi over the parrot's inability to give more accurate predictions. The ruckus is interrupted by the appearance of Satoru Akashi, who gave the Gokaigers the greatest power of the Boukengers a while ago. He then asks the Gokai Galleon crew for their aid in his search for a Precious known as the "The Heart of Hades" - which has the power to resurrect the dead. Though not interested, Captain Marvelous reluctantly accepts Satoru's offer. Upon landing on a forest to begin their treasure hunt, the Gokai Galleon crew and Satoru encounter a Gormin platoon under Insarn - who is also after the Precious for the Zangyack to use. While the others deal with the Gormin in the forms of the Kakurangers and Shurikenger, Captain Marvelous, Luka and Satoru proceed ahead and arrive to a cave where they find an entire platoon of Zangyack soldiers dead. Once inside, they find the Heart of Hades in the hands of a Jaryuu who dies using it to revive an old enemy of the Boukengers: Creator King Ryuuwon. With his new powers, Ryuuwon traps Satoru and the pirates in the cave before attacking the other Gokaigers and driving Insarn off. Back inside the cave, after Satoru points out to him that the adventure he and his crew share is a valuable treasure, Captain Marvelous remembers how he and Aka Red found the Bouken Red Key. Though Satoru feels they need to destroy the Precious, Captain Marvelous has another idea as he and Luka blast their way out and come to their crew's aid. When their usual attacks have no effect, the Gokaigers change into the Boukengers with Gokai Red managing to rip the Heart of Hades out of Ryuuwon and throw it to Satoru. But as Ryuuwon still poses a threat due to the residual effects of the Precious, Gokai Silver enters Gold Mode and defeats him with the Gokai Legendream Final Wave. However, it causes Ryuuwon to enlarge into a mindless monster as Gokaioh and Goujyu Rex fight him. After the Dekaranger and Magiranger Keys prove ineffective, the Gokaigers use the Boukenger Keys to unleash an image of DaiBouken, attacking Ryuuwon before fading away with its GoGo Sword used by Gokaioh to destroy the villain with the Gokai Adventure Drive. As the Gokai Galleon sails off, with Captain Marvelous ending up in another argument with Navi, Satoru watches the departing vessel while wondering if this is what Aka Red wanted.

Gai shows his finalized Super Sentai encyclopedia for his crewmates to research how the previous sentai teams fought. Joe, who shows no interest, leaves the Gokai Galleon to pick up food - with Gai following him to learn more about him. During their walk, they bump into a young boy who nearly hits Gai with his bicycle. The boy, Shota, arrives at a nearby shrine to wish for fair weather- only to see Action Commander Stargul holding a black stone. Spotted, Shota and pedals away from the Zangyack and his Gormin, running into Joe and Gai who assume their Gokaiger forms quickly dispatch the Gormin. Despite Gokai Blue turning into Abare Blue to his ally's dismay, he and Gokai Silver as Dragon Ranger overwhelm Stargul before he falls back upon remembering his mission. After the fight, though they notice his wound, Shota tells Gai and Joe that he is fulfilling a promise he made with his friend Daigo to watch the shooting stars on Kamikura Mountain. Though Joe calls the boy an idiot, he mends Shota's wounded leg and telling him to go to his destination. Returning to the Gokai Galleon, Doc obtains information about the black stone, revealed to be the Reiseki Warabe-ishi that when joined to its other half grants its user limitless energy. Joe realizes that the location of other stone is at Kamikura Mountain, where Shota is headed. Fearing for Shota's safety, Joe and Gai head for the mountain, while the other Gokaigers follow suit as Stargul combines the two stones. Fighting a group of Gormin that are keeping intruders away from the submit, Joe and Gai save Shota. Though Gai tries to talk him into leaving, Shota refuses while revealing the full story behind his promise with Daigo as Joe allows the boy to pass to Gai's dismay. By the time they reach the mountain top, the Gokai Galleon crew find that Stargul has absorbed the stones' energy and uses his Meteor Dive ability to summon an asteroid toward Earth. Transforming to negate his ability with his destruction, the Gokaigers use powers of the Goseigers, Dairangers and Ohrangers to overwhelm the Action Commander's power boost. However, refusing to give the Gokaigers the chance to destroy him, Warzu Giru impatiently fires the enlarging beam. Forming Gokaioh to save Shota from Stargul, with Gokai Blue encouraging the boy to continue, the Gokaigers form Shinken Gokaioh with Goujyujin supporting them in destroying the Action Commander. However, in his dying breath, Stargul reveals they are too late to stop the asteroid's course to Earth. When Gokaioh's Gokai Star Burst has no effect, Gokai Silver has Gokai Blue use Gokaioh to throw Goujyujin in the air, enabling the latter robot to destroy the asteroid with the Gokai Dengeki Drill Spin. By sunset, Shota manages to fulfill his promise with Daigo as they watch the shooting stars with the Gokai Galleon crew looking on. Though Gai compares his actions to the previous Sentai, Joe states that Shota did all the work in fulfilling his dream.

As Gai noticed how Luka is treating Ahim like a little sister, Captain Marvelous arrives as Navi's Treasure Navigate hints that the Gokaigers must help others to meet someone. With Gai unable to decipher which Sentai team the fortune relates to, the Gokai Galleon crew resolve to help people out at the nearest town. As Captain Marvelous, with Gai's support, copes with helping old people up the steps and Joe and Doc deal with a transvestite after they give back a ring that he dropped on the sidewalk, Luka and Ahim are in a park where they meet a pregnant woman and her daughter Miku. Then, all of a sudden, the woman goes into labor, but an EMT arrives to get her to the hospital via taxi. By then, Gormin arrive as the girls assume their Gokaiger forms to hold them off using the power of their color-respective Fiveman and Magiranger Keys. Soon after, Luka and Ahim visit the woman at the hospital, where she tells them that the delivery will be soon while learning that the EMT is actually Matsuri Tatsumi of the GoGoFive. After reporting to their crewmates, the girls arrive as Matsuri is attacked by Gormin while she is getting an injured boy into the ambulance. Covering her, the girls are attacked by Rio, Mere and Zubaan. Basco appears and reveals the Gormin attacks are his doing so he can get the GoGoFive team's greater power. Realizing that she was the target on the prior attack on the taxi, Matsuri offers herself to ensure the boy's safe passage, but is pushed back into the ambulance by Luka and Ahim. Motivated by the memory of her younger sister Lia, Luka tells Matsuri that making sure the boy gets medical attention in time should be her only concern as she intends to cover their escape. But Ahim refuses to let her do this and suggests a different plan where she uses Magi Pink's Maagi Magiiro spell to assume Matsuri's form and trick Basco into letting the real one go. Though the plan succeeds, the two are unable to contend with the three extra warriors. Luckily, the other Gokaigers arrive in time and take out the Gormin with Gokai Silver battling Zubaan while the others assume the forms of the GoGoFive to overpower the Rinj?ken users. After the three Sentai warriors are defeated, with Sally taking the Ranger Keys back, Basco unleashes Fireroid Meran to deal with the Gokaigers as he takes his leave. When Magi Gokaioh's fire attack only makes Meran stronger, the Gokaigers use the GoGoFive Keys' greater power to cool the Fireroid down before weakening him with Gokai Prominence so Goujyujin can destroy the monster. Luka and Ahim return to the hospital to see that the boy has recovered from his injuries while the woman has successfully given birth to a baby girl. Luka points out that Ahim is one step closer to becoming a real pirate while Gai notices that the girls' sisterly roles have reversed.

While going out for takoyaki on Gai's suggestion, the Goukai Galleon crew find the owner, Nobuyuki, with Jerashid whom the five senior crew recognize and attempt to leave so not to get involved. However, Gai convinces them to stay to see how it unfolds. Elsewhere, after giving a dull presentation that puts Warzu Giru to sleep, the Action Commander Sen-den has the Gormin litter the town with Zangyack propaganda posters before finding Jerashid. Learning that the alien has become a human's pet, Sen-den attacks Jerashid and Nobuyuki for their defacing of Zangyack superiority. Reluctantly deciding to meddle in the conflict, the Gokaigers use the powers of the Megarangers to waste the Gormin and then assume the forms of the Hurricanegers, Gouraigers and Shurikenger to fight Sen-den. However, Sen-den escapes back to the Gigant Horse, temporarily under Damarasu's command, and asks to borrow a weapon, as his propaganda strategy has failed. Later, after Gai has Nobuyuki apologize to Jerashid for treating him like a pet, Doc suggests that Jerashid should be the man's apprentice instead. Seeing a potential in selling takoyaki in space, Jerashid agrees. However, Nobuyuki's mother has the final word and she disapproves out of health-based prejudices against aliens and to preserve earth culture. By then, Sen-den and his troops barge in, only to be forced on standby until learning from Jerashid that Nobuyuki's mother called him "natural waste", going on a shooting spree with the Zangyack Bazooka. Taking the fight to a nearby construction yard, the Gokaigers fight Sen-den after having Jerashid and the humans hide inside concrete pipes. But when Nobuyuki's mother runs out of the pipes to avoid heatstroke, she unknowingly become Sen-den's target as Jerashid takes the blow meant for her. Pretending to die just to be cool, Jerashid manages to convince the mother that not all aliens are evil before getting her and Nobuyuki to safety. The Gokaigers then use the power of the Timerangers execute Vector End: Beat Defender to destroy the Zangyack Bazooka before defeating Sen-den with a Gokai Legendream/Gokai Scramble combo. After Damarasu fires the enlargement cannons on Sen-den, the Action Commander overwhelms Gokaioh and Goujyu Rex until Gao Lion is summoned. Soon after, Shinken Gokaioh and Goujyujin finish Sen-den off with their respective signature attacks. After the fight, the Gokai Galleon crew learn from Nobuyuki that his mother and Jerashid have eloped and were last heard running a rural onsen with a baby on the way.

While briefing the Gokaigers in the history of the Super Sentai, covering the 22 greater powers that they already have using a chart, Gai fails to notice Captain Marvelous, Joe and Luka sneaking away. After getting ice cream, the three pirates encounter Action Commander Satarakura Jr., who eats their ice cream while revealing his intent to turn humans into chestnuts to power his missile. More furious that he ate their ice cream, the three assume their Gokaiger forms - only to be outmatched by the Space Ninja's antics before his comrade, Sandaaru Jr, arrives. The three Gokaigers battle the two space ninjas using the powers of Livemen and the Abarangers, losing to the duo as the rest of their crew arrive and the ninjas take their leave. Later, after discussing what the space ninjas intend to do, Gokai Silver uses the Bouken Silver Key to track down the villains. Though they get the jump on the space ninja duo and save the chestnuts, the Gokaigers lose them as Satarakura Jr. opens up a void that sucks in Captain Marvelous, Joe and Luka. But as the three shove their crew mates away, Satarakura Jr. takes his leave with a group of Magerappa to support Sandaaru Jr. as he uses his Enlargement Jutsu. Gokai Silver fights the enlarged ninja with Goujyujin in what becomes a losing battle until the unexpected appearance of Fuuraimaru evens the odds - pinning Sandaaru Jr. to a building before Goujyujin finishes him off with the Goujyu Triple Drill Dream. As Fuuraimaru leaves, Gokai Green and Gokai Pink receive aid from a trio of ninjas that dispense the Magerappa. Gai identifies the trio as the Hurricanegers, who explain only their greater power can stop Satarakura Jr. and save everyone. Seeing no trust in pirates, the Hurricanegers demand for their Ranger Keys. Gai defends his crew, explaining that the Ranger Keys would not be on Earth if not for Captain Marvelous, and that demanding for their return is not right.

Revealing themselves, the Hurricanegers ask for their Ranger Keys so they can clean up the Gokai Galleon crew's mess. Though Gai defends the pirates from the ninjas' criticism with intent not to hand over the Hurricaneger Keys, Doc and Ahim give the keys to the trio in hopes of saving their shipmates and the people that have changed into chestnuts. Yousuke does not guarantee the Keys' return, but Ahim assures them that her crew will take them back by force if necessary. Regaining their powers, the Hurricanegers use their Ninpou to enter the pocket dimension of Boki Space; but no sooner are they gone, the three Gokaigers find themselves under attack by a Gormin platoon under Barizorg and Insarn who are ordered to deal with the pirates until Satakura Jr. returns. Within Boki Space, Captain Marvelous, Joe and Luka find themselves as contestants in Satarakura Jr.'s game show, where they must answer his questions correctly so he can say, "Ping-Pong!" to release them. However, the game is fixed with no correct answers and the penalties become more dangerous with every incorrect answer. Finding the three pirates and confused by their refusal to answer the questions, the Hurricanegers barge in to attack Satarakura Jr. However, the attack only prompts the Space Ninja to reveal the bag of chestnuts strapped to an explosive before having the defeated Hurricanegers chained up along with the captive Gokaigers. After Captain Marvelous clarifies why he and his two crew mates are not answering, somewhat winning their respect, the Hurricanegers decide to pull a risky move by offering all the Super Sentai greater powers to Satakura Jr. if he answers their three questions. Accepting the challenge, Satakura Jr. gets the first two right before being tricked via the third question into saying, "Ping-Pong!" Once released, the Hurricanegers manage to recover the chestnuts and leave the Space Ninja with the bomb as it explodes and negates Boki Space. Once back in the real world, the Gokaigers regroup as they transform alongside the Hurricanegers before battling the Zangyack. Seeing their part of the mission fulfilled, Barizorg and Insarn retreat before the two Super Sentai teams use the Gokai Super Ninpou Hurricane Scramble attack to defeat Satarakura Jr., restoring his victims to normal. When Satarakura Jr. is enlarged, the Hurricanegers hand their Ranger Keys back to the Gokaigers as they use Gokaioh and Goujyujin to fight the Space Ninja. Gaining the Hurricanegers' greater power, the Gokaigers summon Fuuraimaru, who combines with Gokaioh to become Hurricane Gokaioh before destroying Satarakura Jr. with the Gokai Fuurai Attack. Back aboard the Gokai Galleon, as everyone gets along, Captain Marvelous tells Yousuke that he likes Earth and appreciates the fact that the Greatest Treasure in the Universe is on the planet. On Gai's suggestion, the Gokai Galleon Crew and Hurricanegers then have their picture taken.

While out shopping, Luka and Doc respond to a scene where Action Commander Regaeru and his troops are attacking a foreigner. All six Gokaigers appear to engage the enemy, with the main five changing into the Flashmen while Gokai Silver escorts the foreigner to safety. In an act of desperation when Gokai Yellow and Gokai Green prevent his escape, Regaeru uses his Reversal Beam to switch the minds of Luka and Doc before retreating. Back aboard the Gigant Horse, though congratulating the Action Commander for crippling the Gokaigers, Warzu Giru reprimands Regaeru for failing in his secret operation and orders him to proceed as the pirates are still in the dark about it. Meanwhile, aboard the Gokai Galleon, as Gai feels that he saw the foreigner from somewhere before, the astonished crew members are figuring how to get Luka and Doc back to normal. Luka (inside Doc's body) decides to go out with Doc (inside Luka's body) forcing herself to tag along. During their shopping spree, Luka chases off two boys harassing two high school girls; in return, the girls exchange phone numbers and take pictures of themselves with him - Luka takes a much delight in it to Doc's dismay. But things get worse for Doc when two mobster-style men chase after her, only to find out the two are actually jewelers who want to hire Luka for her exquisite taste in quality jewelry before Luka gets rid of them. Luka asks Doc why she didn't jump to the next building during the chase, he is shocked to realize that Doc is more concerned about the well being of Luka's body. Back aboard the Gokai Galleon, Gai remembers that the foreigner is the president of a western country, and that a world peace conference is being held today. The crew figures out that Regaeru's plan was to switch the minds of Zugormin units with the state heads in attendance, causing all nations to unconditionally surrender to the Zangyack Empire. Calling Don and Luka, the Gokai Galleon crew arrive at the peace conference as Regaeru is about to switch the world leaders' minds. All guns blazing, the Gokaigers kick Regaeru and his troops out of the building before Gokai Yellow and Gokai Green finish off the Action Commander with their Gokai Scramble variation. As a side effect, the duo return back to normal, but an enlargement beam revives and grows Regaeru. Gokaioh and Goujyujin double-team the Action Commander before Hurricane Gokaioh finishes him off with the Gokai Fuurai Attack. Later, when Doc's date with the two school girls ends terribly due to his dullness, Luka cheers him up by telling him he is cool in a strange sort of way. When Doc asks what is cool about him as they return to the ship, Luka slugs him in the stomach to shut him up.

Shortly after defeating an army of Zugormin, the Gokai Galleon crew go out to have a meal when they are confronted by the legendary bounty hunter Kiaido, who once defeated Captain Marvelous in the past. Due to this previous encounter, his presence immediately brings fear into Captain Marvelous. The Gokaigers' use of the Biomen and Maskmen's powers prove ineffective against Kiaido, who allows them to retreat, as he is disgusted with fighting weaker opponents. Back aboard the Gokai Galleon, as the crew tend to their wounds, Navi reveals in a treasure navigation that the villainous foe can be defeated with a phoenix. When Gai immediately identifies the clue as a reference to the Jetmen, Captain Marvelous has the crew split up and search for that team's former members. Meanwhile, aboard the Gigant Horse, Warzu Giru reprimands Kiaido for allowing the Gokaigers to escape, but the bounty hunter is defiant as he explains that he intends his increase their bounty while have them get stronger to slake his two desires for combat and wealth. As Joe, Luka and Doc proceed on their search, a man on a motorcycle hits on Luka and steals Joe's Mobirate before speeding away. The same man appears before Captain Marvelous's group, though only he and Ahim can see him while Gai thinks their captain is hitting thin air. Questioning the captain's abilities as a red warrior, the man proceeds to beat Captain Marvelous down and then steals his Mobirate. Telling the pirates not to look for the Jetmen, the man introduces himself as Gai Yuki. After Gai informs his shipmates that Yuki is the missing Black Condor, Captain Marvelous later encounters Yuki again, who tells him that his lack of courage and stubborn pride will keep himself from acquiring the Jetmen's greater power. Following him to a cemetary, Captain Marvelous discovers Gai Yuki's tombstone; the crew are stunned and Gai realizes that Yuki, who only his shipmates were able to see, is actually a ghost who does not want the other Jetmen involved with Kiaido. Confronting Kiaido on his own, Yuki changes into Black Condor and overpowers the Gormin platoon before squaring off against the bounty hunter. Seeing that Black Condor is intent on fighting after death, Captain Marvelous regains his courage as he and his crew take over. After Captain Marvelous and Joe regain their Mobirates, Gokai Silver finds himself occupied with the remaining Gormin while the main five Gokaigers change into the Jetmen to finish off the bounty hunter with a Jet Phoenix-style attack. Later, with Gai still unable to see him, Yuki gives the Gokaigers his blessings before departing back to Heaven's Golden Gate bar to resume playing cards with God.

Warzu Giru comes down with the common cold as Insarn deduces that the happiness of women is needed to cure him. Barizorg employs Action Commander Dial to carry out the task. Dial targets newly-wed brides, attracting the attention of the Gokai Galleon crew. The Action Commander enlarges himself and the Gokaigers respond by summoning Gokaioh and Goujyujin. However, Dial shrinks himself down and takes control of Goujyujin, using it to battle Gokaioh, before going over to take Gokaioh over. However, Gokai Red, Gokai Blue, and Gokai Yellow damage the giant robot while they chase Dial inside of it. With Navi's help, they manage to corner Dial, but he shrinks again and enters Gokai Yellow's outfit until Gokai Pink forces him out with bug spray, forcing him to retreat to the Gigant Horse to clean his eyes. While Doc forces Captain Marvelous, Joe, and Luka to help in repairs, Ahim asks Gai to come with her to get married so they can lure Dial into a trap and destroy his size-changing dial. However, before they could get his staff that holds all his victims' happiness, Dial knocks Gai down and escapes. Ahim pursues the Action Commander, using a series of disguises (student from Turboranger, nurse from GoGoV and policewoman from Dekaranger) to harass him and destroy his staff. The other Gokaigers arrive, but are met by Yukito Sanjyo, the former Abare Blue of the Abarangers. After he introduces himself and his wife, Emiri, Yukito states that he is impressed with Ahim's "Abare" fighting style, and also tells the Gokaigers that Mikoto Nakadai failed to mention that the Abaranger Keys' power can also be used by Gokaioh. Ahim tells him that they only have five Ranger Keys in that set, which would leave her out. However, Emiri presents her with the Abare Pink Key to her to make it six. With Yukito and Emiri taking cover, the Gokaigers assume the forms of the Abarangers and Abare Pink. Embarrassed by her appearance, Ahim stands back while her teammates defeat the Action Commander before everyone uses their Final Wave attacks to finish him off. Barely enlarged by a now ill Insarn, Dial is confronted by Gokaioh and Goujyujin as the Gokaigers use the Abaranger Keys to activate the greater power of the Abarangers: switching their robots' arms. This turns Gokaioh into Goujyu Gokaioh, who finishes Dial off as Yukito and Emiri watch on the sidelines. Later, Gai tells the others of how Ahim managed to put her plan into motion, as she is embarrassed further by the photographs he took on his Gokai Cellular.

When the next fortune from Navi refers to a "skateboarding lion", Gai realizes it must mean Yellow Lion of the Livemen. However, as Gai has no idea where he is, the rest of the Gokai Galleon crew decide to go out and find him. As the others have no luck, Joe and Ahim meet Joh Ohara as he and Joe save an infant. Soon after, the two pirates and Joh find a Zangyack scientist named Zaien who attempts to kidnap a boxer. Transforming in front of him, the two Gokaigers battle the Gormin while Joh gets the boxer to safety before fighting the Gormin. Using the Denziman Keys, the Gokaigers drive Zaien off. The two then find a scanner which Joh learns that it is a technical specification on turning people into beings like Barizorg. After learning the contents of the file, Joe asks Joh to find a way to reverse the process. Accepting to help him, Joh takes Joe to his laboratory to find the means, only to find that the process can not be undone. With this knowledge, Joe laments that he cannot save his friend, as Joh eases his pain by telling of his own tribulations of fighting his own friends and how he intends not to let history repeat itself. As Joe leaves with renewed conviction, he realizes that Joh is the Livemen's Yellow Lion. Meanwhile, after learning Zaien's scheme to convert physically fit humans into beings like Barizorg, the Gokaigers track Zaien down and free his captives before they are joined by Joe. Vowing not to allow others to suffer Sid's fate, Joe transforms into Gokai Blue. As Gokai Silver assumes Gold Mode to take out the Zugormin, the Gokaigers assume the forms of the Livemen to fight Zaien. With Zaien weakened, Gokai Blue personally finishes the scientist off with Sid's trademark attack. Enlarged by a content Insarn, Zaien and the Zugormin battle Gokaioh and Goujyu Rex. Using the greater power of the Livemen, Gokaioh summons Super Live Robo who takes out the Zugormin so Zaien can be destroyed by a Gokai Fuurai Attack/Goujyu Triple Drill Dream combo. Later, Joe vows to defeat Barizorg as he believes it is the only way to save Sid.

At UAOH HQ, Goro Hoshino learns that the Earth Defense Force has been wiped out and the Changemen's greater power taken as he tells his aide Momo Maruo that they must begin their own operation. On the Gokai Galleon, confused by Navi's fortune being "Uao" (sounding like "Wow"), the crew thinks it might have something to do with a roller coaster. They head to an amusement park for clues as they find Momo with a sign as she calls out for the Gokaigers. After she is formally introduced to the pirates by Gai, Momo reveals that she will give them the Ohrangers' greater power in return for a series of menial tasks. The Gokaigers agree until the tasks start to wear on the others when Joe points out that Momo is hiding something from them. Confronting her, Momo reveals that she has been keeping the Gokai Galleon crew distracted so Goro can deal with Basco ta Jolokia so he can get back the greater powers that the privateer took. Elsewhere, Goro has contacted Basco to lure him into a trap with a trade which may provide intel on the coordinates of the Gigant Horse. As Goro's plan fails, with Basco's summoned warriors disarming the explosives laced around the building, Momo prepares to give the Gokai Galleon crew her team's power as ordered so Basco can not claim it. However, Captain Marvelous refuses to be given something that he intends to take by force as he and his crew arrive at Goro's location to help him. Deciding to let the Gokaigers fight their way, Goro and Momo stand aside as Basco has his warriors fight them. As Gokai Silver takes to Gojyujin to defeat Wolzard Fire and Zubaan, the rest of the Gokaigers assume the forms of the Ohrangers while receiving the team's greater power. By using the Ohrangers' signature attacks, the Gokaigers manage to defeat the warriors as Gokai Silver gets the Ranger Keys before Sally can retrieve them. With no more Ranger Keys in his possession, Basco seems defenseless as he signals Sally to stand aside when Captain Marvelous charges him. However, Basco reveals his true monstrous form before easily crippling the entire crew. After revealing that he has the greater powers of the Changemen, the Flashmen and the Maskmen, Basco spares the Gokaigers' lives so they can continue with their quest and make his job of getting the Greatest Treasure in the Universe easier.

Following the Gokaigers' defeat at the hands of Basco, Warzu Giru permits Damarasu to send down Action Commander Shieldon to eliminate the pirates while they are weakened. As Ahim tends to Gai's broken arm aboard the Gokai Galleon, Captain Marvelous, Joe, and Luka work on refining their fighting skills and Doc attempts to develop a new weapon to help his shipmates. Later, on his way from picking up some take-out food, Doc meets a struggling teenage boy practicing his soccer skills so he can be put on the team for their next game. Inspired by the boy's determination, Doc wishes the boy good luck before heading back to the ship to continue his engineering work. The next day, Gokai Green tests out his modified Gokai Gun, which has an additional Gokai Cylinder built onto it, when he is ambushed by Shieldon and his troops. The other four Gokaigers arrive on the scene to dispatch the Gormin, but Shieldon proves himself to be invincible by using his Thick Face Shield to deflect their Gokai Slash attacks, along with the finishing attacks of J.A.K.Q.'s Big Bomber and the Dynamen's New Super Dynamite. Gokai Green's modified Gokai Gun also proves to be ineffective against the shield as its Gokai Cylinders explode from the strain, forcing the Gokaigers to use the Kakuranger Keys to escape. Later, depressed by his failed project, Doc returns to the park to find the boy also depressed at the fact that he did not make the starting lineup. While restoring the boy's confidence and practicing with him, Doc is again inspired when boy mentions that teamwork is important for a team to win. Returning to the Gokai Galleon, Doc asks his shipmates for their weapons to create a better weapon. Captain Marvelous and the others give Doc their gear so he can get to work despite his warning that there is a risk that they could be attacked by the Zangyack Empire while unarmed. As feared, Shieldon and his Sugormin attack the Gokai Galleon the next day. While four of the main Gokaigers fend off the attackers, Doc tries to quickly finish the weapon before Gai points out that the weapon's frame resembles the Ohré Bazooka. With that realization, and remembering Goro's parting words to them of using his team's power for such a crisis, Doc uses the Ohranger Keys to infuse the Ohrangers' greater power into his weapon. Gokai Green enters the battle with the newly-completed weapon, christened the Gokai Galleon Buster, and the Gokaigers vaporize Shieldon with its Rising Strike attack. Shieldon is revived by the growth beam, prompting the Gokaigers to form Hurricane Gokaioh and fight the shieldless Action Commander. Despite his injury, Gokai Silver joins in the fight with Goujyujin before Hurricane Gokaioh destroys Shieldon. Later, the boy tells Doc that despite not making the starting eleven, he will continue to work hard to make the field next time. The rest of the crew notice that Doc is noticeably more confident than usual, as he has accomplished what he set out to do this time. Captain Marvelous, however, reminds Doc to re-attach the Gokai Cylinders back into their other weapons.

Fully recovered from his injuries, Gai intends to make up for lost time starting with cleaning the interior of the Gokai Galleon. While shopping for groceries, Gai, Luka, and Doc encounter Action Commander Zakyura who is under orders to eat up Earth's food supply. They transform to fight him, but he is too much for the three Gokaigers. Once the others arrive, all six Gokaigers transform into the Gaorangers to fight with Zakyura. But Gokai Silver's excitement of being back in action leaves him open to Zakyura's vomit counterattack, canceling his transformation and making him drop his Gokai Cellular. Zakyura then sucks back the food, eating the Gokai Cellular as well, before retreating. Feeling depressed over the loss of his transformation device and the fact that the Gokai Galleon cannot trace its location, Gai leaves to have some time to himself. While walking around town, he bumps into Ryo, the former leader of the Dairangers and now an owner of a Chinese restaurant. At the restaurant, Ryo tries to cheer Gai up with a serving of his specialty gy?za, but Gai tells him he can no longer consider himself a hero without his Gokai Cellular. The next day, the rest of the Gokai Galleon crew scramble to capture Zakyura when he resumes his mission, but he uses his teleportation ability to evade the pirates. When Gai learns of the events while meeting up with Ryo with a bazaar, he expresses his frustration as Ryo tells him that he has forgotten something important to him. But before Ryo can explain more, Zakyura and his troops invade the bazaar. Though he can not transform, Ryo fights off the Gormin as Gai realizes that he became a hero to protect people. The two manage to dispatch most of the Gormin, but are no match for the three Zugormin and Zakyura. The five Gokaigers arrive on the scene, using the Gekirangers' Geki Infusion attack to force Zakyura to cough up everything he has consumed, including the Gokai Cellular. Gai retrieves it and joins the Gokaigers as they change into the Dairangers and finish off the Gormin. Gokai Silver assumes Gold Mode to destroy the Zugormin and the Gokaigers use the Gokai Galleon Buster on Zakyura. When Zakyura and the Zugormin are revived and grown, Gokaioh and Goujyujin are summoned to battle them, but are overwhelmed. At Ryo's insistence, the Gokaigers use the greater power of the Dairangers to execute the Gokai Goujyu Qi Power Bomber on the Zugormin. Gokaioh then summons Fuuraimaru to form Hurricane Gokaioh and execute the Gokai Fuurai Attack on Zakyura, who tries to eat the attack before it destroys him from the inside. Back at the bazaar, Ryo gives the crew a hearty serving of his gy?za while he tells Gai to never to forget the most important part of being a hero. The short lecture, however, causes Gai to miss out on the gy?za meal.

Luka and Doc are shopping together when a group of Gormin crosses their path while one of their Zugormin leaders blasts an acquired coin out of Luka's hand. She is about to attack them when a stranger appears and bribes the Zugormin to walk off so he can talk to Luka in peace. He introduces himself as Cain, an old friend of Luka's and claims he has accumulated a large fortune and now the time has come for them to make her dream come true. However, the entire event was staged as "Cain" is actually Action Commander Vannine, using his power to assume Luka's form while keeping her captive along with the real Cain. Arriving to the Gokai Galleon as the crew were talking if Luka would accept Cain's proposal and leave them, "Luka" arrives on the ship during dinner. Once the crew is asleep, Vannine makes his move in setting up explosive charges before leaving ship to detonate them. Meanwhile, Luka and Cain reminisce about how the former made a promise to collect enough money enough to buy an entire planet for them and the homeless children across the galaxy who have been displaced by the Zangyack Empire to live on. Luka explains to Cain that when she joined the Gokai Galleon's crew, her dream has become even bigger than before as she sees something like Greatest Treasure of the Universe, if as valuable as legends say, would allow her to buy an entire universe with it. Soon after, Vannine returns to announce that he blew the Gokai Galleon up and now intends to kill Luka off. But just as he is about to dispose of Luka, the other Gokaigers arrive to rescue her. They explain that they easily discovered that Vannine was an imposter and after deactivating the bombs he planted, had Fuuraimaru use his illusion technique to stage their ship's explosion to deceive him and follow him to Luka. Enraged that he was tricked as Luka is freed, the Gokaigers fight Vannine. During the fight, as the Gormin hold the others off, Gokai Yellow fights Vannine as the Action Commander assumes her form. After Vannine takes on Gokai Silver's form, the Gokaigers use the Megaranger Keys to expose the imposter before they use the Gokai Galleon Buster to finish him off. After Vannine is enlarged, Gokaioh and Goujyujin have a hard time fighting the Action Commander when he assumes the form of a building to sneak attack them. However, catching on with their heat sensors, Goujyujin cripples Vannine before Hurricane Gokaioh destroys him with the Shushutto Shuriken Chain. Soon after, still wanting to make her dream a reality, Cain bids farewell to Luka while claiming that the happiness she obtained while staying with her fellow pirates is a treasure no money could buy.

The Gokai Galleon crew stumbles on a dimensional hole that has opened in the sky and a robot who falls from it. After it introduces himself as Bomper, the Go-ongers' support robot, the crew takes him to meet the former Go-on Red S?suke Esumi who reveals that the Gunman World is being terrorized by Disruption Officer Chirakashizky, a surviving member of the Gaiark Clan, and that Engines Speedor, Bus-on, and Bearrv have already tried to stop him, but were defeated instead. S?suke asks the Gokaigers to help out, but Captain Marvelous refuses to do so, claiming that they would not get anything from it, particularly after they have already received the Go-ongers' greater power. S?suke decides to go by himself, but after his various failed attempts to reach the hole, Captain Marvelous and the others appear, and he says that he will give S?suke a ride if he wants. The group travels to the Gunman World, where they save several of its denizens from a group of Ugatz. They eventually catch up with Speedor, Bus-on, and Bearrv, and learn that Speedor and Bearrv have married, and that they have a son: Engine Machalcon. However, Machalcon is a reckless troublemaker who spends his time racing around in the Machine World rather than helping out his parents. Their reunion is cut short by Chirakashizky who challenges the Gokaigers to a duel. Captain Marvelous accepts the duel, and despite resorting to dirty tricks, Chirakashizky is defeated by the Gokaigers. During their battle with the enlarged Chirakashizky, the Gokaigers try to use the greater power of the Go-ongers, but they are surprised when nothing happens. Despite the difference in power, they manage to take Chirakashizky with their own power. While the pirates confront S?suke about the reason why the greater power is not working, they are contacted by Pollution President Babatcheed, the new leader of Gaiark, who reveals that he merely used Chirakashizky to lure the Gokaigers into the Gunman World, and by sealing the wall between dimensions, the pirates are now unable to return to the Human World, leaving the way open for the Gaiark Clan to conquer it.

After trapping the Gokaigers and S?suke in Gunman World, Babatcheed proceeds to begin his attack on the Human World. However, this attracts the Zangyack's attention with Warzu coming to Earth with Insarn and Barizorg in what becomes an all-out fight among the villains over who has the greater right to conquer the planet. Back in Gunman World, after the Engines are unable to break the Isolation Barrier around the Human World in their shrunken state, the Gokai Galleon crew set off for Machine World to ask Engine Machalcon, Speedor and Bearrv's son, for his assistance. At first, he is unwilling to help despite his parents' pleas. When S?suke tries to convince the Engine in his own annoying way, an annoyed Machalcon fires at the Gokai Galleon while saying that he will help if they can catch him. The Gokaigers accept his challenge as they use their Gokai Machines to pursue the Engine in his tracks. As Gokai Red points out that the Engine is really running away from his troubles, he has the Gokai Galleon, the Gokai Jet, and the Gokai Racer combine onto Machalcon to slow him down. Finally, admitting that his rebellious attitude is because he has been unable to find anything to fight for, and being jealous of his parents heroism, Machalcon is accepted as a Gokai Galleon crew member as he uses his power to shatter the Isolation Barrier. The pirates leave, leaving Bomper and the Engines behind while promising to come back for Machalcon after handling things on Earth. Once back in the Human World in the middle of the villains' battle, the Gokaigers take on both evil groups as Warzu Giru falls back so the pirates and the Gaiark can kill each other. Using the Go-onger Keys, the Gokaigers defeat the Gaiark grunts before overwhelming Babatcheed and then using the Gokai Galleon Buster to defeat him. After activating his Industrial Revolution enlargement sequence, Babatcheed battles Gokaioh and Goujyujin before S?suke tells the Gokaigers to use his team's greater power since they have formed a partnership with Machalcon. Summoned into the Human World, Machalcon combines with Gokaioh to form Go-on Gokaioh who scraps Babatcheed. Soon after, as Machalcon returns to Machine World with the promise to come to their aid when needed, S?suke is impressed with the Gokai Galleon crew's ability to befriend the previously rebellious Engine and asks if can join their crew, as well.

After successfully defeating Goujyu Gokaioh, an excited Warz Gill triumphantly returns to the Gigant Horse while leaving Barizorg to hunt down the remaining Gokaigers. On Earth, after finding Doc, Luka, and Ahim, Gai admits that he feels Captain Marvelous's sacrifice to save them is not right. The three admit they too feel betrayed by their captain's action and intend to give him a piece of their minds. As the rest of the Gokai Galleon crew evade the Gormin while making their way to the Gokai Galleon, Joe's own dash to the ship is halted by Barizorg who more engages him in a duel. Though outmatched, Joe manages to effectively kill the cyborg. Soon after, Sid's spirit appears before Joe and tells him to rejoin his shipmates to continue reaching for their dreams together. After news of Barizorg's death reaches him, a furious Warz Gill sorties out in the Great Warz to vengefully obliterate the Gokaigers, despite Damarasu's pleas. As this all occurs, after having a dream of Aka Red reminding him what it means to be a pirate, Captain Marvelous wakes up and finds Navi at his side. After taking Navi's advice to fight the Zangyack to consideration, Captain Marvelous uses the Gokai Galleon to blast his reunited crew's pursuers. When they reunite, he apologizes for his earlier action before they all transform into the Gokaigers to take on the Zangyack forces. After defeating the Dogormin with a Rising Strike/Gokai Legendream combo, the Gokaigers form Gokaioh and Goujyujin when the Great Warz returns to Earth. Though they overpowered in every way, with Machalcon being their last greater power left to fight with, the Gokaigers' intent to see their dream through causes the Gokaiger Keys to glow. Realizing that they have found their own greater power, the Gokaigers have Gokaioh and Goujyujin create the Kanzen Soul and combine with Machalcon to form Kanzen Gokaioh. With their new power, the Gokaigers have Kanzen Gokaioh destroy the Great Warz, with Warz Gill caught in the resulting explosion. Later, as the Gokai Galleon crew accept their official declaration as the thirty-fifth Super Sentai, a mournful Damarasu recovers Warz Gill's body from the Great Warz wreckage as he watches the Gokai Galleon sail off into the night with utter hatred towards it and its crew

Following the death of Warz Gill at the hands of the Gokaigers, the Zangyack have increased the bounties of the space pirates — with Captain Marvelous' head set to an "Unlimited Reward" which means that anyone can name their own price. Aboard the Gokai Galleon, Navi's latest navigation fortune involves Moroboshi High School, which Gai immediately identifies as the school where the Megarangers attended. Though Gai explains that the Megarangers have long graduated from Moroboshi High, the Gokai Galleon crew decides to investigate nonetheless. Upon arriving at the high school, the crew meets Kenta Date, the former Mega Red who is now a teacher at the school. Overhearing them talking about school, Kenta tells the Gokai Galleon crew that in order to obtain his team's greater power, they must become students for the day. Though only Ahim and Gai look forward to this venture, the others begin to open up and enjoy high school life while developing a connection with the students who are moving toward their dreams. Having been watching them from afar, Kenta sees Sally on the campus and follows the monkey into the forest. Gai, suspecting something is up, follows him. Kenta searches for Sally when he is confronted by Basco who has come to steal the greater power of the Megarangers. Gai shows up to protect Kenta just as Basco reveals that he has planted multiple time bombs in Moroboshi High which will go off in 10 minutes unless Kenta surrenders the greater power to him. Having overheard the conversation over the Gokai Cellular, Captain Marvelous tells Kenta not give in to the privateer's demands. While Gokai Silver changes into Magi Shine to protect Kenta from Sally, the rest of the Gokaigers are aided by Kenta's Digiken students in locating the bombs all over the school with the other students' help. However, Basco defeats Gokai Silver before he proceeds to take the greater power from Kenta. Gokai Silver uses the Gosei Knight Key to use a Defense Gosei Card against the attack before the other Gokaigers arrive on the scene, revealing that they used the Timeranger Keys to freeze-compress the bombs. As Kenta returns to the school, the Gokaigers change into the Megarangers. Gokai Red and Silver take on Basco, while the others fight Sally. When the Gokaigers attempt to destroy the damaged Sally, Basco blocks the Gokai Supernova and Slash attack before unleashing the Pseudo-Lifeforms Woodroid Moririn and Soilroid Dororin from the space monkey's body and carrying his pet to safety. After using Magi Gokaioh and Fuuraimaru to weaken Dororin and Moririn, they form Kanzen Gokaioh to destroy the two Pseudo-Lifeforms. As the day comes to an end, Kenta fulfills his end of the deal by giving the greater power of the Megarangers to the Gokai Galleon crew as their "diplomas". The pirates then take their leave as Gai tries to talk them in sticking around for dinner with Kenta.

As the Gokaigers have lunch, Goujyu Drill makes an unexpected appearance. After investigating his mecha's bridge, Gai finds a Time Emblem containing a video message from Domon, the Timerangers' Time Yellow. He tells the Gokaigers to travel back in time to October 2, 2010, to protect the currently destroyed Megakure Temple as it will lead them to another greater power. He also warns them not to interact with anyone in the past as it might cause some complications. They accept Domon's request, using the Time Yellow Key to take Goujyu Drill into the past. Arriving to the temple, the Gokai Galleon crew find a young boy about to be attacked by the Strengthened Nanashi Company. The group assumes they are responsible for the future destruction of the temple with Gai protecting the boy as the rest transform and chase after the Strengthened Nanashi when they are called for. Eventually, the Gokaigers spot the Goseigers and Shinkengers during their battle with Buredoran of Chimatsuri's army of Nanashi and Bibis. They then notice Shitari of the Bones gathering the Strengthened Nanashi, planning to ambush the two Super Sentai, deciding to return the favor to the teams for giving them their greater powers in the future by destroying him and his forces. Back at the temple, Gai tries to take the boy home before learning the boy ran away from home due to his mother being a journalist who moves them around before the boy can make friends. Gai tells the boy that he was like him when he was little, always moving due to his own parents, but he always made friends in each place and despite knowing he might move, he would always have friends everywhere. He encourages the boy to make do with his situation and look forward to tomorrow. By then, the Matroid Zan-KT0 of the Shot arrives to destroy the temple under orders from Metal-A of the Agent to acquire the large energy presence detected inside. Gokai Silver fights Zan-KT0 before the other Gokaigers show up to deal with their true target by weakening him with the Timeranger Keys before defeating him with the Gokai Galleon Buster and the Gokai Legendream. However, Metal-A notices this and uses the newly gained Bibi Bugs to enlarge Zan-KT0 to gather data on the Gokaigers. However, after Zan-KT0 is destroyed by Goujyujin, Metal-A decides to leave as improvement on the Zan-KT schematics is more vital for the Matrintis Empire to eliminate the Goseigers. The Gokaigers meet with the boy's mother and the boy, whose name is revealed to be Mirai Moriyama, thanks Gai for his words as the crew take a group picture of the temple with Mirai and his mother. As the Gokaigers return to the present, they realize they never received the hint to the greater power which appears to be related to a strange bottle that is located inside the temple. In the future, Domon checks inside Goujyu Drill to finds his Time Emblem, along with a letter from Gai holding the group photo. Though disappointed that they interacted with the past, Domon is shocked when he recognizes the woman as his girlfriend, Honami Moriyama, and is moved to tears when he realizes Mirai is the son he never knew of.

When Zangyack Emperor Akudosu Gill takes over the conquering of the Earth, he sends Imperial Guard Zatsuriku to take out the Gokaigers, and Ahim plans on destroying him herself as he is the one who destroyed her homeworld.
