believed Vector had killed Marin, alongside Nash, however they were saved by Abyss who transferred their souls into the bodies of Reginald and Rio causing them to live on as children with amnesia. When they regain their memories they decide to leave Yuma's group and rejoin the Barians. Her new ace is "Number 103: Ragnazero". Using "Rank-Up-Magic The Seventh One", she can upgrade her monster into "Chaos Number 103: Ragnafinity". Although she is absorbed into Don Thousand in the series' climax, Astral revives her and she chooses to live out the rest of her life as Rio. An Emperor from Barian World, he manipulated Dr. Faker and Vetrix to achieve the Barians' agenda of destroying Astral World. After his first defeat, he orchestrated a new scheme by taking on a human form on Earth and calling himself Ray Shadows, becoming friends with Yuma Tsukumo is a gambit to orchestrate the latter's fall. When that failed, Vector released the Barian Deity, Don Thousand, and became his current host. He is also known for being extremely cruel towards his dueling opponents and fellow Barians and is incredibly insane, which leads him to random fits of deranged laughter. Vector uses an "Umbral Horror" Deck. He was in possession of one "Number" monster, "Number 66: Master Key Beetle" which he used to lure Yuma and his friends into a trap. His ace is the Over-Hundred Number, "Number 104: Masquerade". Using "Rank-Up-Magic Barian's Force", he can upgrade his monster into "Chaos Number 104: Umbral Horror Masquerade". He leads his fellow Emperors, Girag, Alito and Mizar and to a lesser extent, Vector against Yuma and his friends. A conversation between himself, Girag, Alito and Mizar reveals they saved Vetrix, granted him some of the abilities of Barian World and returned him to his own world and requested he collect the "Numbers" and destroy Astral World as compensation for their altruism. With the defeat of both Vetrix and Dr. Faker, Dumon is determined that they would have to do it themselves. To that end, he sent his comrades to Earth to search for the "Numbers". He would also come to use his former comrade's name, Nash, as his alias when in human form on Earth. He uses a "Star Seraph" deck, his ace monster being "Number 102: Star Seraph Sentry". Using "Rank-Up-Magic - The Seventh One", he can upgrade his monster into "Chaos Number 102: Archfiend Seraph".
