Yu-Gi-Oh! 5D's

The Revived Hero (4x57)

:

Z-ONE claims to be Yusei from the future, though Yusei refuses to believe this. Z-ONE sacrifices Zero Machine Ein to activate Infinite Machine Ein Soph, a trap that allows him to summon more than one Temporal Machine God at a time with any releases, but will still lower their attack points to zero. Z-ONE then summons 3 more Temporal Machine God monsters through his trap's effect. He then attacks Yusei's Black-Winged Dragon with his Temporal Machine God Tzaphion, in an attempt to utilize its ability, which would send all of Yusei's traps on his field back to his deck. Yusei however, counters this, activating Scap-Iron Scarcrow, saving himself from the attack. Z-ONE then attacks with the other 2 Temporal Machine Gods, using their abilities to restore his life points to 4,000, with Zadion's effect, to return Yusei's monsters to his deck, and to deal him damage, with Camion's effect, which reduces Yusei's life points to 1,500. Due to the damage, Yusei's duel runner then plummets towards the ground. But before he crashes into New Domino City, Yusei manages to regain control of his duel runner, and fly back to the duel. Z-ONE then taunts Yusei of still having hope in this desperate situation, and says that like Yusei, he himself used to have hope, until his failure taught him that the only way to save the future, was to destroy New Domino City. Yusei then denies this, stating that he will still have hope not matter what happens, and tells Z-ONE that he is not him. Seeing that Yusei still refuses to believe him, Z-ONE decides to show him his memory. Z-ONE then explains he was a scientist, who used technology to make himself into a copy of Yusei, in hopes of restoring hope to the people, so that their emotions would stabilize the Ener-D reactor. But then, after all that he had taught them, the humans went back to own their greedy ways, and the Ener-D reactor then chose to self-destruct. So Z-ONE's effort became in vain, when the all of the Machine Emperors self-destructed,
