Science Ninja Team Gatchaman

A huge turtle-shapes mecha, the "Turtleking" attacks a uranium storage facility. The ISO and the delegates of various countries are very concerned. Nambu, the only person who previously knew of Galactor, now officially anounces the existence of both the criminal organization "Galactor", as well as the Science Ninja Team that has been formed to resist them. The Science Ninja Team receives Nambu's orders, unites in the God Phoenix, and flies off right away to a missile launching base where the mecha was sighted. Ken stops Joe, who's eager to get into his first real fight. Ken takes Jun along and they sneak inside the mecha. With Ken's help the God Phoenix then enters the mecha and Joe, Jinpei and Ryu join the battle against the Galactor members. Elsewhere, the commander of the mecha tells Berg Katse of the Science Ninja Team's existence. Katse then relays the message to Governor X. In accordance with X's instructions, Katse orders the Science Ninja Team to be destroyed. The order is to have the mecha make a suicidal plunge, taking the God Phoenix with it, thus burying the Science Ninja Team. But at the very last moment, the God Phoenix escapes the mecha by using the Firebird Effect.

A spaceship disappears, along with a device that can report and record the location of the Earth's resources. The Science Ninja Team receives Nambu's instructions and heads towards the bottom of the sea, in the vicinity of the spot where contact with the spaceship was lost. There, prawn-shaped bulldozers leave a huge aircraft carrier located on the sea bottom to build a uranium factory. Ken stops Ryu who wants to fire a Bird Missile, and sneaks into the aircraft carrier alone.

Deadly crashes involving passenger planes keep happening. Ken, who's investigating these occurrences, encounters a boy named Makoto. The boy is awaiting the return of his father who was reported missing in one of the accidents. Makoto's father is the younger brother of the inventor of Uranless, Dr. Takahara. The string of plane crashes has been caused by Galactor. They are intent on getting the Uranless, since it is capable of neutralizing the means of propulsion of their giant mummy. Ken has encountered the mummy in his Cessna before, and because of that incident, he has data concerning the propulsion system of the mummy. He contacts Dr. Takahara in order to get the Uranless.

During the investigation of an incident, Ken visits the Institute for Earthquake Research. Because of an earthquake caused by a mecha, he falls along with the director of the institute, into a crevice in the earth. Ken transmutes and is saved, but he cannot rescue the director. Ken stands before the director's grave and is attacked by the director's daughter Naomi, who firmly believes he's Galactor. Ken understands her anger at not being able to avenge her father and decides to let her know about his true identity as member of the Science Ninja Team. Consequently, he lets her join the team on the mission.

Oceangoing ships from the ISO keep disappearing. It always happens in the vicinity of a place called "Cemetery of the Sea". Director Anderson and Nambu ask the Science Ninja Team to go to a base on the ocean floor which is most likely to be struck next. The Science Ninja Team gets Nambu's message and takes the God Phoenix towards the base at the bottom of the sea. Then they encounter a mysterious submarine, which leads them to the Cemetery of the Sea, where they see countless sunken ships.

Gold bars are stolen from the vault of the World Bank. It is the deed of Galactor's Mini Robots. The Science Ninja Team get their instructions and start a search on the islands in the vicinity of the place where the gold bars seem to have been taken. Joe makes sure that Ken, Jun and Jinpei, in civilian wear, attract the enemy's attention and get taken off to the base. He proposes that if this is the headquarters, it should be destroyed right away. However, Nambu stops him by saying it's not the Science Ninja Team's duty to attack. Joe leaves a bored Ryu behind in the God Phoenix on the bottom of the sea and sneaks into the base in order to prepare for retaking of the gold bars.

There's a new kind of plane that does not pollute the environment. In the middle of Ken's test flight of this ISO-developed plane, he is attacked by a biplane, piloted by a man who introduces himself as "Katzen Berig". Katzen Berig lashes with his whip at the ISO plane, causing it to crash, but Ken saves himself just in time by deploying a parachute. Nambu suspects from the name that Galactor is involved and orders the God Phoenix to attack immediately, but the God Phoenix's tailfin gets damaged by the whip. Analysis of the material stuck in the hull of the God Phoenix reveals that this kind of metal, called "super metal whisker", is something that has been researched by the ISO, but not manufactured. Nambu is taken aback at the scientific power of Galactor, but when the production factory is discovered, he gives the Science Ninja Team the order to destroy it.

A secret base. In order to resist their terrible enemy, Nambu thinks about a base for the Science Ninja Team. But fearing enemy intervention, he gives the Ninja Team orders to fly a patrol at Point G in the southern Pacific Ocean. Following orders not to intervene there, the God Phoenix leaves a smoke screen and flees when it encounters a sea anemone mecha. That night, Jinpei is with the other four team members, but he is not tired at all. He takes the G-4 and dives to the bottom of the sea. Children in the park had told him that G-4's popularity is the lowest of all the team members, and he intends on gaining their favour by being the best. Despite the worries of the other team members, he wanders around the sea bottom searching for the mecha. He never notices that he is being tailed by the mecha he seeks.

In the deep black sky the blue-white moon is shining. Suddenly, a meteorite falls down to Earth. According to analysis, the meteorite has the same composition as the moon. So Ken proposes approaching the moon in the God Phoenix to investigate. Approaching the moon, the God Phoenix encounters a swarm of meteorites heading for Earth. Ken discovers a wrapped up body in the middle of the swarm and, because this is not a meteorite he attacks. But the Bird Missiles have no effect. The body falls to the Earth, becomes a Scorpion Mecha and attacks an oil refinery.

Suddenly, a whole city has lost power. Ken, in his Cessna, is thinking about an anomaly in the power plant when he gets a message from Nambu that the nuclear power plant has been attacked by a large group of ants. The Science Ninja Team goes to the site in question, but since the missiles would have hardly any effect on the tiny groups, they wash them away by breaking a nearby dam and using the force of the water. Upon analysing an ant they brought back, they learn that it's a finely and precisely manufactured robot.

While flying, Ken is surprised to encounter the plane of the Red Impulse commander. He pursues him, but Red Impulse gets away using some superb flying technique; Ken longs to be able to use similar techniques. The Science Ninja Team gets order to guard the super powerful plane "Blue Hawk", pride of the country Toritan. But the crew of the plane has been killed before take-off and has been replaced with Galactor members. Nambu learns of this situation after take-off. He mobilizes Red Impulse in order to protect the Science Ninja Team from the Blue Hawk, since it is more powerful than the God Phoenix. The God Phoenix continues to accompany the Blue Hawk without knowing the situation onboard. Red Impulse appears, attacking the Blue Hawk and, after shooting a timebomb into it, disappears again. Ken sees that and firmly believes that Red Impulse is actually an enemy. Ignoring Nambu who wants to stop him, he pursues Red Impulse alone in the G-1. While Ken is away, the other four members get abducted and taken to a base located in a volcano. Ken however follows Red Impulse, who in turn is following the signal emitted by the time bomb. They arrive together and save the team just before they're executed. Nambu tells them that Red Impulse is a friend battling on their side. The G-1 and the Red Impulse plane fly through the sky wing-to-wing, reminiscent of bird parents flying with their children. Nobody at the time knows the meaning of the tear appearing in the Red Impulse commander's eye.

The world's raw material for sugar gets stolen by the Galactor mecha Ibukuron, and the world emergency sugar is getting very low. Ryu and Jinpei rush out into the street to buy candies. Just then, they get the order from Nambu to move out in order to follow Ibukuron and find the secret base. During the pursuit, the God Phoenix gets drawn toward the mecha by its strong magnetic force it uses to suck in the raw materials. Ken uses this force to sneak into the interior of the mecha, along with Joe and Ryu.

A ISO constructed storage lake, which is part of a plan to make the desert fertile, disappears. The Science Ninja Team flies to Africa to investigate. An Elder there tells them the legend of the moving red sand. It is said that the red sand burns forever and that it can make civilisations grow, as well as destroy them. Ken asks the Elder about the sand's secret, but the Elder doesn't tell anything. Jinpei, following the Elder who's about to get abducted by Galactor, finds a pendant. The red sand contained in its interior is sent to Nambu and the analysis reveals that it's a new sort of bacteria and also a previously undiscovered powerful energy source. It has a thousand times the force of uranium and, if water is added, splits up and causes a big explosion. Because Galactor is looking for the red sand, a lion ant mecha changes the lake's location via an underground channel. The God Phoenix dives deep underground, discovers the caves used by the mecha and sneaks into the base they discover. But Galactor learns of the Science Ninja Team's arrival and they shoot the Elder after he reveals the secret. They head to the location where the red sand is locked up, one step ahead of the Science Ninja Team. Before dying, the Elder tells the Science Ninja Team the location as well. The God Phoenix gets there too late, the red sand is already stolen by the mecha. As a last resort, the God Phoenix turns toward the mecha as the Fiery Phoenix. As the red sand is touched by the flames, Galactor's high ambitions are burned, together with the sand.

It is reported that all kind of nuclear ships (cruise ships, submarines, battle ships etc) are disappearing. It is the deed of the Galactor mecha Icecander, aiming at nuclear energy. While investigating these incidents, the Science Ninja Team gets a message that a suspicious iceberg is moving forward against the current of the sea. The God Phoenix follows the iceberg, going to the north pole, where they discover a base in the middle of icebergs. Ken and Jun sneak into the base.

The town "Ghost City" has been destroyed 10 years earlier by environmental pollution. Communication with an investigation team sending data from there is lost. The Science Ninja Team goes there in the God Phoenix, which uses a soft skin (membrane) to protect it against the pollution. But as soon as they enter the city, they meet a Galactor attack. As it turns out, there's a base here. Nambu orders the U.N. military forces to attack. It seems everything is cleared after the attack. In reality however, a jellyfish lens created by Sosai X continues to grow at the bottom of the sea near the city. It uses the polluted sea water as its amniotic fluid.

The latest ISO weapon factory is used by Galactor and manufactures Mekanika. It's a machine which, according to the plan on a microfilm, can change its form constantly. The Science Ninja Team follows Mekanika. But when they lose sight of it, they continue searching individually before meeting in Nambu's house. While searching a tunnel where they lost sight of Mekanika, Jinpei discovers a base through a hole in the surface and sneaks into it. While trying to destroy the base, he finds a micro cassette. Judging from the behaviour of the Galactor members, this cassette seems to be very important and Jinpei takes it with him while fleeing. It contains the plans needed to change the form of Mekanika. Nambu makes a new plan, based off the cassette, and instructs the Science Ninja Team how to install this plan in Mekanika.

X, intending on using the strong destructive tendencies of humans, especially children, releases Kabutoron in the city. It destroys things using the children's brain waves. The children are happy when they find big stag beetles in one of the open areas, something which rarely happens in town. Also Jinpei finds one of the bugs and brings it home. In that night, each of the children's stag beetles grow large and they pull the children inside their bodies, fly out the room and start to destroy the city. While flying, Ken discovers how Kabutoron attacks a nuclear plant. But since Jinpei is missing, the God Phoenix cannot take off.

A huge whale keeps attacking harbours. While investigating a group of whales, the Science Ninja Team discovers a huge whale heading for this group. The huge whales fires a rocket aiming for the God Phoenix and flees, pushing aside the other whales. In reality, it's a Galactor submarine camouflaged as a whale. They want to follow the huge whale submarine, but, in order to save a young whale under attack by orcas, the G4 flies away. During all this, the submarine gets away. Nambu reproves them because of their squeamishness and puts a transmitter on the small whale so that he can help in the search for the big whale. The God Phoenix goes to the Arctic Circle, following the small whale. In order to search for the base, Ken and Joe leave the God Phoenix and encounter two men who introduce themselves as forest-keepers, but are then attacked from behind. Ken is baffled. Joe says that this is Galactor's trick and that his parents got murdered by the very same trick.

The Ruman Kingdom is known as the Gambling Kingdom. Galactor, guaranteeing the king's position, is channeling millions in riches out of the country. His highness Prince Luga's heart is torn by the people moaning with the high taxes imposed by the kingdom. So he contacts the ISO and offers to hand over a microfilm containing the location of the Galactor bases and headquarters to them. He does this knowing that it's against his father the king's, orders. In order to lay their hand son the film, the Science Ninja Team takes part in a race sponsored by the prince in which everybody can participate. But the encounter obstacles set by Galactor, who know the prince's plans. They're lured, together with the prince, into the base located in the interior of the kingdom.

A Galactor mole mecha appears. The Science Ninja Team is contacted and starts to meet, but on the way there, Joe wants to save a small dog beside his mother, who was killed in the attack. Joe suffers a rocket attack. The mecha starts attacking the God Phoenix as well, but, since it gets weak in the sun, it has to withdraw at dawn. In the examination it becomes known that Joe got hit in the head by a fragment of the rocket. Since it's a very dangerous area an operation is impossible. Also the attempt in the high speed centrifuge fails. Then a message arrives saying that the mecha has appeared again.

A horse owned by a doctor who is an authority in the area of cyborgs, participates and wins with an astonishing performance at the world-famous horse grand prix. When Nambu sees this video, he guesses that this horse is a cyborg. He orders the Science Ninja Team to guard the Doctor so that his astonishing cyborg technique is not abused. But when Ken and the others arrive, it's already too late. Only one Galactor badge has been left behind and the Doctor has vanished. Dr. Henjinman has been brought to the base where he recognizes X's real face. He threatens X, saying that he will reveal his secret if he is not made X's representative. X reluctantly agrees.

A uranium mining factory at the bottom of the sea is attacked by the mecha "Kingdragon". Since a guard vessel with much more power than the God Phoenix was beaten during the attack, Nambu does not order the Science Ninja Team deployed. But Ken disobeys Nambu's orders and goes to face the mecha in the God Phoenix. But the God Phoenix is no match against the enemy and even their trump card, the firebird, is beaten by the much higher temperatures. Nambu orders the Red Impulse group to attack the mecha, but the Red Impulse commander believes that Ken should face the enemy again and refuses Nambu's order. So Nambu comes up with another plan. He wants to install a cooling device in the God Phoenix, which is then supposed to react with a minus bomb to be installed in the interior of the mecha to freezing the enemy. Knowing this will be very dangerous, Ken applies for the job of installing the minus bomb.

From the cellar of a bowling alley, the "Mecha Ball" appears and starts to destroy the city. Because of the Mecha Ball's simple structure, an attack is futile since there is no weak point. Opposing his four eager teammates, Ken decides not to go out, saying that if they attack without a chance for winning, they will only die a useless death. At the same time, Ken watches Jinpei move a pachinko ball with a magnet and gets an idea how to defeat the mecha. When Nambu hears Ken's proposal, he immediately builds a huge electrical magnet in the middle of the alps and decides that the God Phoenix must lure the mecha there.

Scientists from the ISO headquarters are murdered one after the other and Nambu orders the Science Ninja Team to act as bodyguards. The Science Ninja Team separate for their guard duty. During Ken's guard, he surprisingly meets Galactor's Ninja Blackbirds and follows them, but loses sight of them near an amusement park. At the same time, Jun and Jinpei are attacked by a Neon Giant which appeared accompanied by the sounds of a flute. In order to let the scientist escape, they offer themselves as bait, but fall off the street. Jun reports that the Neon Giant resembles the Indian statue standing before the amusement park where the Black Birds vanished. Because of that, the Science Ninja Team waits for the night and sneaks into the park to start investigating.

An ISO volcanic research center is attacked. The God Phoenix, starting the investigation, is surprised by the Magma Giant and escapes into the sea where the Giant cannot follow it. When Joe says that the Magma Giant's face resembles the face of Jesus Christ sculptured into a steep slope in the national park, the Science Ninja Team goes there to investigate. A girl climbing the Jesus Christ sculpture is suspected to be a Galactor agent by Joe and questioned, but she answers that she's here to sculpture the statue, continuing the tradition of her family in the third generation. Together with the girl they go into the cave found in the steep slope and discover a base. The Jesus Christ face sculpted in the slope, is plunged into lava seething in the interior of the base and comes out as the Magma Giant. Seeing this, Ken calls the God Phoenix. At the top of the base, there's a special glas which is actually at the bottom of a sea. The sea is used as a lense to heat the magma, using the sunlight. With a rocket, they break the glas and thus destroy the base. When a message comes in from Nambu that the Magma Giant is heading towards a city, the Science Ninja Team split up in their individual machines and lure the Magma Giant towards the sea. The Magma Giant cannot resist and steps into the sea. Through the sea water he's instantly cooled and becomes a black piece of rock, standing still. The girl then gets her chisel to begin sculpting again.

ISO ships are attacked one after the other by Galactor's black ray. And because Ryu is napping in the God Phoenix, he cannot be mobilized. Ryu feels responsible and gives Nambu his bracelet back, while shaking off his teammates who want to stop him. He then goes back to the fishing-village where he was born. During this time the fishing areas in the village become polluted through unknown causes. Since Ryu's father is the co-operative head, is blamed by the village people. Ryu tells his father to ask Nambu to analyse the sea water. In the analysis, a matter is found which results from a process to produce metal. Nambu thinks it's Galactor's deed and arrives in the fishing village with the Science Ninja Team.

The ISO gets a message from Lucy, one of the executives at Galactor, that she wants to reveal the location of their headquarters in exchange for $ 10 billion. Therefore they contact Lucy by having Joe team up with her in the world customer car endurance race across Africa. The other 4 team members are going to act as guards for their scout. After Joe gets into the car, he expects the information immediately, but Lucy says it's not possible until the rally is over. On the way, they are attacked by mechas camouflaged as animals. It is Galactor who have come to know of Lucy's treason. But with Ken and the other's help, they escape the attacks and continue the rally. As they approach the finish line, Lucy asks her old friend Joe whether they don't want to team up and take over Galactor. Evading all kind of obstacles, the team of Lucy and Joe wins the race and gets $ 100'000 in prize money. In the tea room, Joe demands that Lucy gives him the information as offered. When Lucy tries to answer, she suddenly starts to move strangely and finally breaks through a wall and falls to the ground where she explodes. She was a cyborg manufactured by Galactor, and a radio signal emitted by X caused her to self destruct. Joe is taken aback by Lucy who is now nothing more than a pile of iron fragments. His anger towards Galactor is ignited again.

Children keep dissolving into thin air. Even the members of the Science Ninja Team become eye witnesses to one of the disappearances. Ken follows some tire tracks on the ground and enters a mirror maze. There he discovers some snail mechas, but they become transparent and disappear. Galactor is collecting children with strong brain waves in order to produce the brain wave monster Alphagila. The monster reads the secrets of the ISO in its institutions, and then destroys them. Nambu enhances Jun's brain waves for a while and makes her pose as a bait. The Science Ninja Team locates her radio signal, sneaks into the base beneath the mirror maze and saves the children.

Jinpei and Ryu visit the Shirayuki orphanage where Jinpei grew up, in order to play with friends. The children beg them to take them to watch some kickboxing. At the same time, in a volcanic area, strange things are happening. Ken and the other two go to investigate, but don't find anything extraordinary. After watching the fight, the children go to ask the winner, Galack X, for an autograph. They learn however that he was trained with deadly weapons in his boxing gloves. They are caught by the female assistant and taken away. Ryu, following Galack X by Jinpei's request, battles with Galack X, but gets hurt. He contacts Ken and the others.

A water shortage is occurring everywhere. As if to pursue the beaten enemy, an invisible enemy continues to pound, destroying dams and water tanks. The Earth is put into a grave situation. The God Phoenix is mobilized and discovers the flying mecha Kamisoral which has become a white shadow. Merely flying past it causes great damage and missiles are useless since they can be cut apart by the mecha's sickle. The Science Ninja Team somehow manages to escape and report to Nambu. During this time, an announcement from Katse is received saying that tomorrow will be the last day for mankind.

Nambu's car is attacked by Galactor. But because of Joe, who seems to remember the Devil Star's rose bomb, they escape by a hair's breadth. Everybody wants to fully concentrate upon protecting Nambu since he's targeted. But Joe cannot agree with them and leaves the villa. In order to control his anger, Joe runs his car around a racetrack. When his parents were murdered, he too suffered a lethal wound by a rose bomb. His memories revive and he thinks of revenge. Just then, he has to save a woman from an accident on the track. Before parting, they make an appointment to race on the track together the following day.

Receiving a warning from Galactor, the Science Ninja Team mixes with the other citizens and starts to investigate. But thinking this might be a Galactor trap, they take off their bracelets and split up in the city.

The Science Ninja Team doesn't know where Jun and Jinpei are, and Gezora starts to attack. But with two of them missing, scoring is difficult for the team.

Strange radio waves attack people together with an aurora. Afterwards they run amuck and cause grave accidents. While fishing, Ryu is also bathed in these radio waves. Because Ryu's speech and behaviour are strange after he comes back to the base, an investigation is conducted. It results that Ryu's brain waves are like those of a cat. Additionally, Nambu is touched by those radio waves as well. In a rage, he tries to activate the switch for the self-destruct mechanism of Crescent Coral. Joe punches him out.

In the country Doria, oil springs have been discovered. A battle has started between the King, keen on the mining rights, and the Prince, who's on the side of the poor, revolting people. It has become a civil war. Now there's also a never sleeping force, intent on making this into a world war. The King, in a disadvantageous situation in this war, asks the Science Ninja Team for help. The God Phoenix sneaks into the country in firebird mode. Ken contacts Prince Ali and convinces him to talk one more time with his father, the King. Together they go to the palace. But the King's answer is a volley of bullets, aimed at the prince and his companions. Ken stops the Prince who wants to attack the King. They both are dropped through a hole in the floor into a subterranean prison, where they find the skeleton of the true King. Ken tells the God Phoenix to come and get them, thus escaping.

An ISO research ship is attacked and data regarding uranium resources on the bottom of the sea is lost along with it. In the middle of the investigation, the Science Ninja Team discovers three persons, a father and his two sons, floating on the sea. They say they witnessed the occurence while fishing. But in the village they live, the brothers Taro and Jiro and their father have the reputation of being liars. Nobody wants to listen to their testimony that they saw an apparition of a crawfish and a moving lighthouse. Ken discovers that the squid the family fished out is a rocket. The Science Ninja Team decides to have a look at the lighthouse.

Dr. Miwa is researching whether the surface of the Sanjo Lake, frozen over the whole year, can be used to produce strong energy from the sun, instead of using polarization glas. Now he has gone missing. He had questions because this year the lake wasn't frozen over and seemed to have started an investigation. Nambu orders the Science Ninja Team to look for him since he fears the misuse of the Doctor's research, but also because the Doctor is his friend. The Science Ninja Team, led by the Doctor's pet Taro who was able to get to Nambu with a camera, heads towards the snowy mountains. There they discover a Galactor base. The Science Ninja Team and Taro are tricked by the Doctor's reflection. Taro is washed away by water falling from the ceiling of the base where the surface of the lake is located. The Science Ninja Team is locked up by walls made of reinforced glass.

As part of the Mantle plan, a pollution-free city is constructed in the desert. Nambu and the Science Ninja Team have come into the city for the inauguration. In the middle of the parade, a man who introduces himself as the archaeologist Dr. Mukashiski is distributing leaflets for a dinosaur exhibition. That night, the city is attacked by dinosaurs, and Ken sneaks into the dinosaur exhibition from Dr. Mukashiski. It turns out to be a jungle from the dinosaur period. Ken is caught by ivy made of metal and can escape into a subterranean sewer, but his bracelet is taken away this time. The Doctor takes the bracelet and, in order to make this is own merit, hides it.

Outside of Earth's atmosphere, a Devilstar ship appears. Spores of the Jigokiller plant are released towards Earth by Katse's hand.

Jinpei is lost in mourning in Jun's empty shop. Elsewhere, Nambu is absorbed with the research on the Jigokiller plants.

Invited by Jun, the Science Ninja Team visits a concert by the popular rock group Demon 5. The Demon 5 is kidnapped by Galactor right in front of them. Galactor has Demon 5 play the murder music composed by X. Using a Sonic Mecha, they start to play this music high above the city. The music destroys buildings and drives people crazy. The God Phoenix is mobilized, but meeting a counter-attack, it's forced to retreat for the time being.

During his vacation, Ryu asks a passing car whether they can take him with them. But the car is part of a Galactor plan to free prisoners. Ryu is consequently captured by Galactor and taken along to the Jinjin prison which houses only prisoners sentenced to death that have tried to escape earlier. Galactor, upon arriving in the prison, kills the guards and has the prisoners assemble in the prison yard. The plan is to make them Galactor members. Ryu is in the midst of those prisoners, but because he has taken away his bracelet, he cannot get into contact with Ken and the others. He decides to go along to the Galactor base.

The two countries of Bien and Ameria suffer from a long war. When the two countries finally make peace, their respective representatives standing for peace, Romina and Julia, get married as a symbol of peace. However, Galactor is planning to prevent the marriage of the two, to start the war again in both countries. The Science Ninja Team serves as bodyguard during the honeymoon trip. Joe thinks that the man he met in the airport, who supposedly has the same convictions as Romina, is suspicious. So he follows him, but loses sight of him near an old temple. Meanwhile, Romina and Julia are captured by Galactor robots. Ken and the others, still doing bodyguard duty, follow them, but lose sight of them.

Galactor's Arkeo attacks the Moroi City. But Nambu judges that the Science Ninja Team is no match for the mecha's shock wave, therefore they don't receive orders to move out. Even when an announcement sent by Galactor arrives, the Science Ninja Team only gets an order to stand by. The Team ignores Nambu trying to stop them and gets mobilized. But they end up in a dangerous situation when they're hit by the mecha's shockwave. They are saved by Red Impulse.

A secret mining factory of the ISO is attacked and the island on which the factory is located is besieged by Galactor. In the mine, an ore containing more energy than uranium is being mined. If this ore were to fall into Galactor's hands, the consequences would be catastrophic. Opposing the ISO which demands the protection of the ore, Nambu insists that saving the people has priority. The Science Ninja Team and a group of transport ships head towards the seal island where the factory is located. The island is hidden all year in a fog, and also Galactor is just standing there without being able to intervene. One group sneaks in, ducking under a Galactor attack, and gets near the island. They send G-4 to the island and he decides to get the workers out of there to the ships. He is able to hide them in a group of seals that had been surprised by a Galactor attack and are seeking shelter in the sea.

Ken is maintaining his beloved plane at the airport when a man with a gun forces him to fly a plane. Since Ken's plane has only a single seat, the man makes him fly another plane made for two people. During the flight, Ken seizes an opportunity and tries to take away the man's gun. However, the man fires a bullet which hits a wire in the fin tails of the Cessna, making it impossible to control the plane. The man, using the only parachute on board, escapes, saying that he will go to sell information to the ISO. Ken makes a forced landing, but because of that shock the radio device in the bracelet ceases to function. Ken sees a Galactor Mecha and follows the man who heads towards a valley. There is an abandoned Galactor mine there. Ken and the man are captured and hung up in an old well. The man has betrayed Galactor for money and has hidden a tape in the well which contains an overheard discussion between Katse and the Prime Minister of a certain country. Ken transmutes and rescues the man, defeating all the Galactor members in the building. But in an explosion occuring at that time, the man, who has seen Ken's true face and has followed him, is badly hurt. The Galactor commander, who got out alive, is about to attack them with a mecha. The man entrusts the tape to Ken, along with a message to his mother living in Hontwall, then he throws himself and the Galactor commander towards the bottom of the valley. What remains is the tape, which was smashed by the commander, and one name. "Kelly, Arthur Kelly is my name".

In order to finish an ultracomputer, Director Anderson himself is hand-carrying the core of this computer in his private jet to the research institute in the Jetol plateau. Galactor anticipates this, and starts to move in order to steal the component before it reaches the heavily fortified research institute.

Galactor plans to use the Shutterkiller to copy data from ISO institutions and to then destroy those institutions. The ISO institutions are attacked one after the other. The Science Ninja Team guards the institution which is most likely to be attacked next and, shortly pretending to have been defeated, follows the mecha in the G-4. Jinpei finds the Galactor base in the middle of the desert and goes on digging into the earth with his G-4. In addition, the other four team members follow him and sneak in. But when they enter the base, the G-4 machine is left unmanned. They start looking for Jinpei, and find a factory which restores the copied ISO data. Splitting up, they continue with destroying the factory and looking for Jinpei.

The Science Ninja Team is accompanying Nambu, who came to the ISO headquarters for a conference. Jinpei discovers a car with the emblem of Galactor, hides in the car and goes to the Galactor base. But when he wants to get into contact with Ken, he is captured. Meanwhile, in Nambu's office, a message from Katse arrives saying that he will blow up ISO buildings unless the Science Ninja Team hands over some data regarding newly discovered uranium ore. Despite knowing that it's a trap, Nambu mobilizes the Science Ninja Team.

In the country Inderia, droughts and heavy rainfalls occur every year. In cooperation with the ISO, a plan to build a dam in the hinterland to create lots of arable land is being made. But through mysterious events which are happening again and again around a shrine which will be inundated by the dam, the plan is progressing only very slowly. At long last, the Torakodon skeleton appears. The Science Ninja Team gets the order to investigate and sneaks into the country. Events like a landing transport plane exloding on the runway the God Phoenix was supposed to use, show the handwriting of Galactor. Jinpei and Ryu, staying in a cheap hotel, get involved in a murder case.

The Science Ninja Team follows Nambu's orders to come to Huntwall to spend their free time there. Only Ken doesn't trust those instructions. At that moment, a man in a white suit, being pursued by the police, appears and Ken helps him. But when they hear from the police commander that that man is a Galactor, the Science Ninja Team is on alert. While flying his Cessna, Ken is attacked, but saved by the Red Impulse commander. The man in the white suit is the Red Impulse commander. He asks Ken for help to get the legal proof that the defense minister of that country concluded an agreement with Galactor. He then tells Ken that he spent 10 years to stop Galactor's plan, abandoning his family.

To be able to see his father! Carrying this wish in his heart, Ken follows the whereabouts of the mecha. Before him somebody is shot and wounded. It's Sabu, a friend from Ken's childhood. When Sabu sais that he saw Ken's father in Huntwall, they both go there. In Nambu's office, Katse makes a bold appearance in disguise. He leaves saying that if the world does not surrender to Galactor in Huntwall, the V2 plan will be realized. The V2 plan is the terrible plot to make the Van Allen belt descend with a special rocket, thus extinguishing mankind with radioactive flames...

The Galactor rocket explodes in the Van Allen belt and humankind enters the worst crisis ever. Upon the message from Galactor saying that a rocket restoring the belt will be launched if the world surrenders within 24 hours, the representatives of all countries assemble. They feel the time pressure and want to come to a conclusion. Nambu tells them to believe in the Science Ninja Team and puts an autolock on the doors so that they won't open until the following morning. The Science Ninja Team is mobilized to take away the Galactor rocket and to restore the Van Allen belt. At approximately that time, Ken sneaks alone into the construction facility for the rocket. In order to complete the rocket within the timeframe, it is changed from automatically controlled to manned. Ken, in the middle of Galactor members who are sleeping, tired from the now finished incessant work, emits a bird signal. But then Katse's gun is pointed at him. Ken transforms into birdstyle. The gun of the Red Impulse commander, who sneaked in as well, is then pointed at Katse. The God Phoenix breaks in and Katse escapes and the defense minister falls to his death. Taking the responsibility, Ken says he will get into the rocket himself. Jun then tells him that Red Impulse himself is Ken's father. The dream of Ken to reunite with his father also becomes their eternal separation at the same time. The Red Impulse commander throws Ken away and gets into the rocket himself. Ken runs after him, calling for his father. In Red Impulse's mind, the figure of Ken in his youth is turning around. The rocket disperses across the sky and Earth is saved.

Katse, who got into his stride by the funeral of Red Impulse, plans to destroy institutions related to uranium in the whole world.

The sea takes up 70% of Earth. Galactor makes Nambu and the Science Ninja Team chose between their lives and pollution of the seas by PCB. Pretending to agree, the God Phoenix goes to the pre-defined area in the sea, but when they blow up the approaching mini submarines, the pollution matter streams out and the Tarushia Sea ends up polluted. Ken discovers three tankers which seem to control the mini submarines and, using the mini submarine loaded into the God Phoenix, sneaks in. There, cleaning work is done for the returning mini submarines. Ken is discovered by Galactor. He defeats them and heads towards Katse's whereabouts, but in the meantime the tankers have transformed into one huge tanker which emits a magnetic force attracting the God Phoenix whose hull starts to crack.

Jun is attacked by a group of bikers. Koji saves her, he is a former race champion and Jun's friend from childhood. Now he has become the commander of a Black Bird squad and is on the way to blow up the missile base of a certain country. When he wants to install the time bomb, the figure of Jun, the way he encountered her, crosses his mind. Without installing the time bomb, he runs away from the base. Jun sees his figure and reports to Nambu. She disagrees vehemently however when her comrades voice the opinion that Koji is a Galactor.

Mike Miller, a sniper, has been released from prison after 35 years. Galactor gives him a small tank with a freeze gun on board and orders him to eliminate the Science Ninja Team. Three observation satellites high above the south pole are shot down. Guessing that this is Galactor's fault, the Science Ninja Team heads towards the South Pole. Katse is awaiting their arrival, accompanied by a small tank. Joe tells Ken to pursue Katse and goes after the tank, but the freeze gun freezes him along with the G2 car. The rest of the team heads out in order to fight in their individual machine, but when Ryu sees how Jinpei is done for, he heads towards the tank without thinking and the G-5 gets frozen as well. But when Mike aims at Jun, he hesitates one moment and the bullet misses. Besides, the gun is starting to burn because of the continuous use. The fire is fanned by the G1 and the fallen over tank goes up in flames. Ken and Jun approach Mike. He asks them why they didn't fight using weapons. Ken answers him that their individual machines are not equipped with weapons. Mike shows Ken the cores of the bullets he secretly took away and tells him that his comrades are not dead. He also says that he missed the shot at Jun because he saw in her figure his daughter from whom he was separated 35 years ago. Then he dies. Inside the God Phoenix, which is on its way home, Ken says that if they wished for weapons, it wouldn't be them to try outdoing Galactor.

The Jet Cutter, developed by the ISO to gain energy without causing pollution, is stolen. Nambu gives the order to recover it. Ken opposes him, asking whether they have to pay for the faults of the ISO. It's because of a lack of reason which makes him think that he wants to attack the enemies of his father. Jinpei starts crying at the argument between the two men. When Ken sees this, he reluctantly agrees to be mobilized.

A fishing-boat is in the vicinity of Ghost Island and becomes eyewitness to a big ray and cuttle-fish. Afterwards, it is swallowed by a huge waterspout and is shipwrecked. On Nambu's orders, Ken and Jun land on the island and start to investigate. As night falls, the two of them see how previously defeated Galactor mechas appear explode as they are swallowed by a waterspout. They are convinced that there has to be a mecha factory. They defeat Galactor members who have come searching for intruders and take their place. Then they sneak into the base.

During an experiment with Galactor's brand-new mecha, the research machine crashes. Katse commands the termination of the survivors. The Science Ninja Team arrives at the crash site of the machine. It is not clear what the purpose of that machine was. They discover a young man and bring him back. The young man has lost his memory. He and Jinpei become good friends. When the name of Galactor is said, the young man shows a strong reaction in his motion nerves. He goes out on a motorcycle together with Ken. They are attacked by Galactor and from that shock, the young man remembers the location of the base, the weak points of the mecha and also that he himself is a Galactor. Ken wants to go to confront the mecha and take the young man with them. The young man declines, suffering from the fact that he's Galactor. However, Ken convinces him to go with them. Jinpei then addresses him as "Science Ninja Team G-6". Ken and the young man sneak into the mecha. While Ken attracts the enemy, the young man seeks the device to reverse the flame and laser gun, the weak point of the mecha. However, he is captured by the commander and told to shoot Ken with the gun given to him. Ken tells him to think this over. The young man points the gun at him, saying that this is his destiny. The bullet and Ken's boomerang fly away at the same time. The bullet pierces the commander, the young man is hit by the boomerang. He tells Ken where to find the reverse mechanism, then he breathes for the last time. In his report to Nambu, Ken tells the following: Through G-6's death defying deed, the mecha could be blown up.

Ken is flying over the country Hontwall in his G1 plane. He is shocked when he sees the three Red Impulse planes. The figure in one of the machines is undoubtedly his father. When the Red Impulse commander asks him whether he should lead Ken to the new base, Ken gets into contact with Nambu. However, without listening to Nambu trying to stop him, Ken heads towards the base. Nambu orders the God Phoenix to investigate what is going on in reality. However, the God Phoenix encounters a mecha without the G1 on board. It is caught and brought to the base.

A celebration is held in order to praise the merits of the Science Ninja Team. However, the participants are super robots. They were invented by Nambu with purpose. His plan is to let them be intentionally captured by Galactor. Then based on their message, learn where the location of the enemy base is, have the real Science Ninja Team sneak in there. But Ken thinks that the enemy will not be fooled by them, so he takes the place of his robot.

Professional baseball players disappear in front of the spectators during a short power outage in the middle of a match. Nambu thinks that it's Galactor's fault and according to his instructions, the Science Ninja Team are keeping guard everywhere in the baseball stadium. During another game, a similar power outage happens, and the players disappear before their eyes again. This time however, Jinpei, who was acting as a ball boy on the field, has disappeared as well.

A year earlier, the northern country Flanbel escaped from the rule of the Dictator General Somure. But Galactor, who instructs Somure, appears in the mansion of the Prime Minister and tells him that he either obeys or dies. By the demand of the governor, the Science Ninja Team sneaks in through the secret back door. On the peace memorial day, presents are distributed to the children by the governor. But the Suimusa group, which Jinpei met, have their presents stolen by children from the upper city quarter.

The conserved brains of famous doctors keep getting stolen. A monster also steals the brain of Dr. Yamashina, an expert in robot engineering. The Science Ninja Team follows it, but lets it get away. But Nambu gets a hold of one of the tentacles from the monster. Analysis shows that the monster is the low life form Bem from space. Nambu fears that if Galactor's scientific powers can control space life forms, they may be able to revive the dead brains.

The queen of the country Monarins is a big fan of the Science Ninja Tea. Every year, she donates big amounts of money to the ISO. Katse comes into the country himself, planning to weaken the activities of the Science Ninja Team by killing that woman. Elsewhere it is predicted that a Galactor assault may take place during the fashion show and the Science Ninja Team is put on guard duty. Ken and the other sneak into the country as common tourists.

Katse, opposed to Sosai X's orders to destroy the Mantle Plan, asks whether it wouldn't be better to conquer Earth after the Mantle Plan was finished. X promises to Katse the rank of President Z and lets him start the operation. But behind his back, X laughs and says that Z is a symbol for murder. Institutions of the Mantle Plan are attacked one after the other by a jellyfish mecha. The God Phoenix faces it, but its missiles have no effect. On the contrary, the launching ramp gets hit. The God Phoenix wants to escape with the multiple firebird. But mines are released upon the God Phoenix and it is wrapped in flames in no time at all. The God Phoenix makes a forced landing in the desert and explodes in the end.

One day on a small island in the south sea, a nuclear explosion takes place. The ISO research planes crash and burn in the high radio-activity. From the remaining records, they learn that in the vicinity of the island there's radioactivity, but not in the center of the island. The God Phoenix is supposed to go to investigate, but in order to overcome the radioactivity belt, they have to use the Firebird on the way in and out. Beauce of this, they request a research ship to supply them with fuel.

Galactor sneaks into the country Shosken, 80% of which is taken up by the Ohara desert and mountainous regions. Communications break off with a special troup which went there to investigate in the old tombs. In order to search for them, the Science Ninja Team splits up and mixes with the citizens. A woman confuses Jinpei with her dead son. But he sees his mother in her as well and goes to her house. There he hears the story that in the old tombs, which are called the devil's cemetery, caravans and people from the village disappear.

Mummified corpses keep being found. Since the dammages continue, Nambu orders the Science Ninja Team to find out the cause of all this. During a patrol, Joe saves a girl from a taxi which is being attacked by mannequin mechas. He takes her to the hospital. But Ken blames him for not contacting him from there and doesn't trust the girl.

The ISO discovers a new energy source in the Himalaya, but an investigation troop sent there is annihilated by the Yeti. Because of several rumours about Yetis, Jinpei goes to the Himalaya alone. There he is attacked by the Yeti, but it is a Galactor Yeti Mecha. The God Phoenix goes to the Himalaya to look for the missing troop according to Nambu's orders. They get the message from Jinpei about the apparition of the Yeti and head towards the location this message came from.

In Amazonia the old entemologist (insect researcher) Toda who is continuing his research, notices unusal behaviour in the locusts. He notifies every authority and department, but he is not taken seriously. Jinpei, who heard his story, returns with him to Amazonia.

The Science Ninja Team vanquishes another mecha and has let Katse escape yet again. With Nambu's transmission, they follow the course of Katse's rocket. However, Katse has switched to a car and heads towards a jungle. The Science Ninja Team descends towards the jungle as well in his pursuit and separates into three parties, searching for Katse. X receives an SOS signal from Katse and, together with sending a commando unit, takes additional steps by setting traps in the jungle. Joe criticizes Ryu for approaching a trap unprepared. But when he distrusts a wounded young deer, Ryu retorts that there's nobody more insensitive than Joe. Meanwhile, Jinpei discovers Katse and corners him, but is in turn caught by the commando unit. Before an ice covered mammoth, Joe and Ryu discover Jinpei about to be turned into a human sacrifice. They save him and additionally corner Katse, who changed into a shinto-priest. But Katse seeks refuge in the mammoth mecha and attacks Joe and the others. They are saved by a hair's breadth by the God Phoenix and Joe wants to shoot a rocket into the mecha. But when he sees a group of deer below the mecha, he hesitates. Luring the mecha into the mountains, they shoot at the ground below the mecha with a rocket. The mecha disappears into an avalanche. The Science Ninja Team is wrong in assuming that, because of the jungle with the traps set, the headquarter is nearby. Its existence is however still shrouded in the fog.

The mammoth which should be buried in a glacier, appears at an amusement park where Jun and Jinpei have gone. While saving the children, Jun's shoe falls off and gets stuck between the mecha's claws. Jun reports the loss of her shoe. Nambu tells her to look for it. He says that, with Galactor's scientific power, they might be able to discover the secret of the transformation from the shoe.

While a Galactor mech is mobilized, one of the small planes loses speed and collides with the fisher boat on which Ryu's father is. The boat is shipwrecked. When Ryu's younger brother Seiji hurries to Ryu's whereabouts and tells him of his father's shipwreck, Nambu's mobilization order goes out. Ryu desperately shakes his brother off, who is crying and clinging to him. But he ends up being late for the mobilization and the main research institute is already destroyed. Shortly thereafter, while they are doing bodyguard duty for a tanker, Ryu is worrying about his father's shipwreck as well and misses the course. In the meantime, the tanker has been attacked.

When the mobilisation order from Nambu comes in, Joe is in the middle of a race. Because he finishes it, he is too late. On the way to the meeting he transforms. The electrical waves emitted while transforming are intercepted by Galactor and Joe is targeted by the completed Megazainer. His leg is hit by the high frequency and its transformation is undone. Joe falls behind a rock, Dr. Misuno however is afraid of an explosion because of the continuous use and retreats.

The country Dokual is rich in Earth's resources. But because it declines to pay supporting money to Galactor, the President's life is threatened. The Science Ninja Team receives a call for help which reaches the ISO. They hide the God Phoenix at the bottom of the sea and secretly go to the President's residence. On the estate, several traps have been laid, but it is explained that they're only there to protect the President. The five of them meet the President, but from the fact that the President holds the cane in the hand opposite the side of his bad leg, they see through the Black Bird's disguise.

A research institute for the Earth's crust, which is located at the bottom of a deep sea canyon 10'000 meters below sea level, breaks off a connection. Ken and Joe go to the research institute in "Marin Saturn" in order to investigate.

Secret information regarding the Science Ninja Team is stolen. Nambu orders the Science Ninja Team to investigate why the ISO scientist Boronbo acted as a spy and to stop any data from reaching Galactor.

In the country Assham, an uprising has started. Traces of a confusion ray appear on the body of the leader who has been shot. Thinking that a few hundred people have been bathed in that ray, the Science Ninja Team sneaks into the country. During the investigation, Ken and Jinpei notice that the peackocks, which are the country's national birds and which are bred and released in the country, are robots. The peacock mechas cover the two men with confusion rays. Ken pushes Jinpei away and saves him from the rays, but he is attacked by the Peacock Devil, which then takes with him the car Ken has hidden in. Ken's boomerang remains behind.

BC Island is an island ruled by Galactor. A man visits the grave of Giuseppe Asakura and his wife, which has not been visited by anybody for ten years. Because the man on the photo transmitted is disguised and looks like Giuseppe, Katse goes to the island. It is said that Giuseppe's child died in the hospital it was brought to, but when Katse learns that the man who brought that child was Nambu, he has the child's grave opened. It is empty. The order to capture the man is issued to the whole island. While escaping Galactor's continuous pursuit, that man, Joe, encounters his friend from childhood, who is now Father Alan. At midnight Joe, who has been wounded, appears at the church and asks him to shelter him. While Alan is treating him, Joe learn's from Alan's words that the Devil Star girl he killed earlier was Alan's fiancé. Slipping by Alan, who left, Galactor enter the church and Joe collapses because of the bullets. At that time, the Science Ninja Team has learned of Joe's past and hurries to him. The Science Ninja Team has defeated Galator, but then Alan appears holding a gun. Alan points the gun at them, asking who Joe, the Condor is. Ken answer that it is him. When Alan's finger touches the trigger, Joe's bullet penetrates Alan's chest. However, Alan's gun did not hold a bullet. Joe wails that Alan was the most needed man on this island. By the hand of the inhabitants of the island, a solemn funeral is held for Alan. Behind the rows of people, the God Phoenix takes off.

Dr. Misuno, a Galactor, succeeds in diminishing the earlier invented detection device, which discovers the electrical waves emitted when the Science Ninja Team transforms. Galactor plans to use it in an operation to track down the Science Ninja Team and follow them to their base. They rebuild some previous mechas and have them rage everywhere. Catching the short moment when the Science Ninja Team transform, they succeed in their plan. The Science Ninja Team, not knowing the Galactor plan, reunites in the God Phoenix, and wants to attack the mechas. However, Nambu suspects it's a Galactor trap and orders them to return to the Crescent Coral, leaving the mechas to the UN troups.

During construction of a subterranean factory of the ISO, Galactor attacks and a drill falls into a crack in the Earth. Since the energy source of the drill is uranium, it is predicted that, when the drill touches the magma, a huge earthquake with a magnitude of more than 8 will occur. The Science Ninja Team, together with the geologist Dr. Karig, goes to collect the drill in an Earth investigation car, with the G-4 in the lead. The time limit is ten hours. On their way, they encounter an ambush from a mecha. Ken gets into the G-4 and, acting as bait, lures the mecha away from the car. He then shoots his boomerang, converted into a time bomb, into the mecha.

The scientist Demon tries to sell his own invention to Galactor by using it to attack a cargo plane, which carries goods for those in need. He hates Nambu, who has been battling him for a position in the ISO as a schoolmate. For leaking information on the mecha and thus luring out Nambu, Katse makes it a condition that the true faces of the Science Ninja Team should be revealed. Nambu agrees to Demon's invitation and goes out to an airfield. Demon notices that the Science Ninja Team secretly acts as Nambu's bodyguards. He takes a picture of the figures with a small camera hidden in his eyepatch, then throws a small bomb. The Science Ninja Team understands that their uncovered faces have been photographed and they lose their courage.

The message is intercepted that Galactor spies will sneak into Utoland City. With a funny look to the Science Ninja Team, who are guarding the frontiers, the spies just walk in.

The world sugar reserve is about to be exhausted. The artificial sweetener Shugare is developed as a substitute, but when the distribution starts, sombody buys it all. Because of the message that Shugare has been found in the water flowing out of the Bikkuiero mountains, the God Phoenix goes there. There they find a crashed cargo plane. From the wreckage it turns out that the man buying up all the Shugare is a arms dealer named Gilman. From the black box they conclude that the loading place for the plane could have been in four different places. They split up the work and start searching.

While on patrol, Jinpei falls in love at first sight with a girl in a holiday house in the mountains. When Jinpei returns, he sees in the news that Maria, the daughter of a great multi-millionaire, has been abducted. He learns that that girl was Maria. Jinpei rescues Maria alone. However, a boy who took on six grown-up men and who disappeared without saying his name raises the suspicion of the local police chief, who is one of Galactor's men. Because there are policemen who saw Jinpei's face, the whole department is sent to search for the boy.

There is a man who has guessed Katse's secret and who has worked his way up in the staff of Galactor. But he is in prison now. He is looking for help in a very safe place. Nambu shows to the Science Ninja Team photos and the records of a female pupil that the man had had. On the back of one of the pictures, which is believed to show the female commander, a name is written: "Katse". In order to search for Katse's secret, Ken and Jun go to the school of the girl in the photos and the remaining three members go to the prison.

Ryu laughs at Jinpei, who is moving earth with the G-4 machine in order to shape a coral reef into a crescent form. The purpose is to turn this coral reef into a bait and lure Galactor there. Nambu goes along with the plan and hands over a special liquid which dyes things red. When something is coloured by that liquid, it is visible on a special radar and cannot escape.

Joe, who is busily maintaining his weapon, is told by Ken that using weapons is a mistake, which results in a dispute. Before his father's grave, Ken is wondering whether, even if they defeat Galactor, a new evil organization will be born.

Galactor has a spy infiltrate a passenger ship with a lot of ISO engineers onboard. He attaches a homing system to the ship and it is then blown up by firing torpedos into it. Nambu, afraid that such a incident may happen again, sends the Science Ninja Team on a patrol. The God Phoenix dives at the spot where the ship sank and encounters crab-shaped tanks. Seizing the opportunity when the Science Ninja Team is distracted by the tanks, a submarine attaches itself to the belly of the God Phoenix. When the crab-shaped tanks are sure of this, they retreat. The Science Ninja Team doesn't trust this move, but they nevertheless go back to their base when Nambu orders them to do so. The Galactor submarine manages to easily sneak into Crescent Coral. The crew kills some engineers disguise themselves and install the homing system in the base.

One after the other, the torpedoes hit right on target.The props of the camouflaging coral reef get stuck in the base which loses its balances and starts sinking towards the bottom of the sea.Inside, the engineers don't want to just leave their research, but Ken and Jun convince them the really important thing is their lives. They make them escape. Meanwhile, while Nambu is destroying the data a big computer falls over and traps his leg, rendering him immobile.

Katse is happy that he has defeated the Science Ninja Team. An order comes in from X to make sure that the Science Ninja Team is dead. Meanwhile, the Science Ninja Team spends its days at Nambu's villa. Without means to do anything after the heavy blow of losing the base, the data of the Mantel plan, and a place to produce missiles. Then the message is received that a tourist city without any strategic value has been attacked. The Science Ninja Team wants to get mobilized, but Nambu stops them and leaves the field to the UN troups.

The Torasshuu power plant provides electrical power to the city of Utoland. Nambu charges its head, Dr. Komibe, with the testing whether a space capsule is fireproof or not. A test which requires the highly powerful incinerator of the plant. That evening, Ken and the others come to the station to say goodbye to Ryu, who is boarding the night train because his father is in critical condition. However, while Joe is heading towards the station, he hits a child and brings it and its mother, to the hospital.

In the Jupiter mountains, there are ruins of a fortress which is said to have been erected by ninjas of ancient times. There some strange corpses are found. Nambu charges Jun, who is familiar with this region, with the investigation. Jun has found Jinpei in the Jupiter mountains. It was decided that this day would be Jinpei's birthday and it has been celebrated ever since. Despite that, Jinpei is in a bad mood that Jun has gone away this year because of the investigation. Ryu tells him that, since he doesn't know when his real birthday is, it doesn't matter when he celebrates it. Jinpei goes to the Jupiter mountains in order to research his real birthday and his origin.

When the ISO intelligence office analyses a horn of a mecha which fell into the Mammoth Canyon, they conclude that with 80% probability the Galactor Headquarter is at the upper course of the Ielo river. Because the Ielo river is a gorge, the God Phoenix cannot fly into it, and Ryu is left with the God Phoenix at the entrance of the gorge. The other four head towards the upper course of the river in a canoe. However, on their way there somebody interferes with them. Elsewhere, this also becomes a hindrance to the Galactor operation of displaying the headquarter, thus luring the Science Ninja Team there. They capture the man.

From the UN rocket launch site the two-man rocket, Leona 3 is launched in order to solve the mysteries of the Milky Way Nebula. Nambu leaves the launch site together with the president in a private plane, but then they are reported missing. The real president has been killed before the launch. Suddenly, Leona 3 deviates from its course. The control mechanism in both the machine and the control center has no effect. As it stands, it seems that the rocket will crash on the Shaku peninsula, resulting in 20.000 dead and injured people. The Science Ninja Team is charged with the search for Nambu, who participated in the development of the control mechanism.

Joe, heading towards a meeting point, is blinded by a light reflection and runs into a woman. Seeing his mother's face in her, he takes care of her, but another blinding makes him feel afraid. At that time, the God Phoenix is forced into a tough battle because the G-2 is missing. Joe, having returned, does not mention that something is not right with his body, and acts up towards Nambu. Nambu orders him to rescue the young air pollution specialist, Mekker, who seems to be developing the mechas. Nambu also asks Ken to secretly help Joe.

The Science Ninja has pursued Katse and arrives at a base. X orders Katse to terminate the Science Ninja Team. They want to reciprocate when missiles are shot at them from the base, but Joe can't focus properly and therefore can't decide on a target either. The bird missile he shoots blindly destroys the upper part of the fortress. The five of them break into the base, but they are guided into a trap and are about to be buried under sand. They escape with the tornado fighter, but because of Joe's blinding, they fail the first time. Ken notices Joe's condition and orders him to stay on the alert in the God Phoenix. Joe goes back to the God Phoenix and is irritated because he has the enemy before his eyes and can't do anything. He punches a panel and causes his fist to bleed.

A by-product of the Mantel plan is the Mantel condensation energy formula whose immense destructive power is kept a secret. In order to bury that equation forever, Ken goes together with Dr. Maxim towards the North Pole Sea in a cargo plane. Underway, a screw in the throttle comes loose and they get into trouble steering the plane. However, Ken puts in a clip as replacement and makes a forced landing. But the cargo plane is swallowed by a sudden crack appearing in the ice field.

Ken is worried about Joe's condition and Joe is afraid of being taken out of the fight. A fight between the two is interrupted by a message from Nambu. Secret ISO circuits are being tapped into and because of interfering electronical waves, the enemy cannot be determined. When Jun says that they may be able to determine the location if they use their bracelets, Joe wants to run off, but Ken stops him. Ken says that it's better to be a couple people only and proposes that he goes together with Jun. Joe gets the order to be on standby and hands Ken his airgun.

A message comes in that a mecha has appeared, but since he can't contact Nambu, Ken goes out based on his own decision. But that mecha is bait to lure the team away from Nambu. Meanwhile, Joe visits an unlicensed doctor. The Female Commander appears, unnoticed by Joe. The doctor watches Nambu, who has locked himself up in his house, pushing his analysing work. Nambu is abducted by Galactor. Joe, who has visited the doctor again, sees the commander, follows her and arrives at the mecha where Nambu is held.

The illness progresses and Joe goes racing at the track in order to shake off his fear. There he is captured by Galactor and dragged before Katse. Katse presses him to reveal the true faces of his comrades. Because he declines, Joe goes mowing down the Galactor members who assaulted him, but he is attacked by another blinding. On the way to the cell he escapes by jumping off the mecha, but he collapses on the street and is brought to a hospital. After regaining consciousness, Joe hears Nambu and the doctor talking on the phone and learns that he has still about a week or ten days left to live.

The mecha serving as bait is destroyed by the God Phoenix. Then, the order from Nambu to search Joe comes in. X is agitated because of the disappearance of Selector. He accidentally tells he will have the Earth extinguished and orders Katse to set the timer in the mantle.

Eerie stone statues appear in the fog. The Science Ninja Team walks around, searching for the entrance. Galactor is there and has spread out a radio net, waiting for a transmission to be sent. And also Joe, who has learned of the arrival of the Science Ninja Team, has mobilized his last forces and has sneaked out of the base, where people were trying to get away.
