Walter Naugus

Ixis Naugus is indeed a deadly sorcerer. He has gone from three separate beings, to court wizard of the Kingdom of Acorns, to enemy of Sonic the Hedgehog and the Freedom Fighters, to servant of Mammoth Mogul, and finally, to mindless beast.

Origin
Agunus the rhino, Nusgau the bat, and Suguna the lobster were perhaps the last three members of the Order of Ixis. (aside from Mammoth Mogul) Their goal was find out just what the Days of Fury, the event that created Mobius, were. (they were later revealed to have been caused by the Xorda) The three, desparate for this knowledge, merged themselves together in an attempt to gain enough power to find out. This resulted in the birth of...IXIS NAUGUS!

Powers and Abilities
Ixis Naugus' most powerful ability is his knowledge of the Ixian Magicks, giving him power over fire, water, earth, and wind. However, when Naugus lost his mind, he also lost these powers, but gained the power to Shadowmeld. This allows him to transport himself through shadows, making him just as dangerous as before. Naugus could also manipulate the Zone of Silence into whatever he wanted when inside of it. But seeing as how it is now the Special Zone and Feist rules over it, it is likely that Naugus can no longer do this.
