Walter Naugus is a powerful magician who seeks to become the ruler of the Kingdom of Acorn. During his time as King Acorn's Royal Wizard, he was banished to the Special Zone along with the king and was trapped for years until he eventually managed to escape. After escaping from the zone, Naugus became an immediate enemy of Sonic the Hedgehog, who has regularly thwarted his plans to take over the Kingdom of Acorn. He has also maintained an antagonism with Dr. Eggman, who banished him to the Special Zone in the first place.
