Ixis Naugus, one of the last surviving members of the Order of Ixis, was born from the fusion of three other wizards: Agunus, Nusgau, and Suguna. During his time as the Kingdom of Acorn's Royal Wizard, he helped instigate events that led to the Great War, and then fled to the Zone of Silence as a safe haven where he was trapped for years until he managed to escape after the First Robotnik War. Naugus became an immediate enemy of Sonic the Hedgehog, who eventually trapped him in the zone again until the Arachne released him once more. After being a prisoner in Dr. Eggman's Egg Grape Chambers, Naugus lost his sanity and blindly served his order's founder, Mammoth Mogul, until his mind was restored by a Chaos Emerald from his apprentice. Following this, he plotted to retake the throne from the Acorn family and succeeded through manipulating the fears of New Mobotropolis' populace, who crowned him king, only to face further difficulties.
