Considered the God of Destiny by Yliaster, the organisation he founded. Zone resides in a strange place which was first accessed by Yusei, Sherry and Bruno through the Z-ONE card that Sherry's parents were murdered over. Since then, Yusei returned as he attempted Clear Mind, Zone gave him a blank Synchro card and insisted there were all sorts of possibilities, referring to Yusei's struggle to keep a clear head during his encounter with Placido; it was their meeting that gave a chance for Shooting Star Dragon to become a part of Yusei's deck.

When Yusei, Bruno and Sherry were transported by the Infinity machine, Sherry was sucked out of the craft and found herself with Zone, who offered her a chance to learn the world's fate, with the price of an altered destiny.

Zone is the creator of Bruno and the Yliaster Emperors in the shapes of his lost friends. His right arm is robotic, shown when he met Aporia and extended a hand towards him. Zone's human identity is presently unknown, his white shell prevents any kind of view of him with the exception of a blue left eye, almost identical to Yusei's.

Zone's intentions were to travel back in time to prevent the world's destruction by an overload of Momentum, watching his only friends Paradox, Bruno/Antinomy and Aporia die, leaving him alone. To do this, he resided in the Arc Cradle—a spiraling destroyed version of Satellite, identified through the ruined Daedalus Bridge—planning to break through to the past world that is the 5D's world and drop the Arc Cradle onto Neo-Domino, eliminating the heart of Momentum's influence. Having enlisted Sherry, Zone showed her a vsion where Yusei would die once he boarded the Arc Cradle, fuelling her warning for him to stay behind and live.

During his duel with Yusei, Zone's mask is cracked revealing his face to be identical to Yusei's. Ths revelation prompts Zone's story that as a scitenist, he lived through the initial attack from the Machine Emperors and in order to give people hope, he remoulded himself after Yusei, with a metal plate over the left side of his incomplete face. Having replicated every detail of Yusei's appearance, he raced off to lead the people from Neo-Domino, having shown the Machine Emperors they weren't a threat. However, when Momentum began to spin in reverse, the Machine Emperors began to attack, like those across the rest of the world. A fissure opened in the ground, swallowing people who cried for Yusei to save them (still believing that Zone was their legendary hero), which Zone failed in. A blast knocked him over the fissure and down a nearby hill, throwing the helmet from him and damaging the metal plate. Devastated, Zone lost hope in Yusei and in mankind.
