Yu-Gi-Oh! ZEXAL - Episode 074
Dumon leads his fellow Emperors after Nasch and Marin's disappearance. He and his a companies saved Vetrix, granted him some of the abilities of Barian World in order to collect the "Numbers" and destroy the Astral World as compensation for their altruism. With the defeat of both Vetrix and Dr. Faker, Dumon determined that they would have to do it themselves. To that end, he sent his comrades to Earth to search for the "Numbers" themselves. He would also come to use his former comrade's name, Nasch, as his alias when in Human form on Earth.
Dumon has the ability to teleport using portals anywhere in the world. Dumon has also been shown to generate a large energy ball which he can use to fly. Unlike other Barians, Dumon is able to stay in his true form even on Earth.
