Yu-Gi-Oh! 5D's - Season 1 Episode 144

Yusei not only has to deal with Antinomy, but also the flames coming from the star. Antinomy brings out his Accel Synchro monster, Tech Genus Blade Blaster, and deals a lot of damage to Yusei. Antinomy talks about how he was a champion Turbo Duelist, before the Machine Emperors destroyed the world. He was rescued by Z-ONE (who is actually the future version of Yusei), before Antinomy could commit suicide by letting a Grannel kill him. Seeing that Z-ONE still had hope (before the events of the Ark Cradle), and that he had none, Antinomy felt shame, and joined Aporia and Paradox as one of the 4 remaining survivors. He then lived his life working with Z-ONE on his experiments to save humankind (which failed), before being revived as a cyborg, after his human body died, whose mission was to teach Yusei the Accel Synchro, in order to provide the power needed to bring Ark Cradle to New Domino City.
