Z-one (pronounced Zone), is a cyborg who serves as the main antagonist of the Ark Cradle arc and the final antagonist of the Yu-Gi-Oh 5Ds anime. He is the founder of Iliaster and is defined by its members, or "The Ancient One", or "The Creator" in the English dub. Along with Aporia, Antinomy, and Paradox, Z-one is effectively the central antagonist of Yu-Gi-Oh! 5Ds, being responsible for all of its other main antagonists in one way or another, as well as for the first Zero Reverse that split Satellite and New Domino City apart. He is from about 200 years after the present day events of Yu-Gi-Oh! 5D's. Z-one comes from an apocalyptic future where he assumed the identity of Yusei Fudo to try to protect humankind from extermination by the Meklord Emperors, but failed to stop the Zero Reverse that destroyed the planet. With the world in ruins and humans nearly extinct, Z-one sends robotic copies of his associates Antinomy, Paradox and Aporia back in time with the mission of changing history and averting the disaster. Though their agenda is noble, the four are willing to go to any lengths to succeed, massacring thousands of innocents. During the Ark Cradle arc, Aporia's incarnations as the Three Pure Nobles plot to bring Z-one's lab, the Divine Temple, into the past to fall on and crush New Domino City. By this, Z-one believes that the discovery of Ener-D can be erased and the end of the world they have lived through will be averted. he sees you
