Ixis

Ixis is a character mentioned in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a dark god apparently worshiped by members of the Troll race, such as the Naugus Twins.

History
Not much is known about Ixis other than rare wellsprings that house the deity's energy exist. Believing Dr. Eggman was using his new energy refinery to harvest Ixis' power, Walter Naugus took control of the refinery with the aid of his allies in an attempt to use its energies to help restore his magic.

Powers and abilities
Ixis generates a potent form of dark and ominous energy that causes power-boosts and mutations, much like the Dark Gaia Energy.
