What If Sonic Never Lost The Werehog Form?
An alternate version of the true blue hedgehog, but this version never had the Dark Gaia Essence within him removed. He's since been on new, altered adventures and wrestling with his inner demons as fate leads him down a dark and thorny path to salvation. He's just as heroic as his counterpart and will crack wise at a moment's notice, but don't risk trying his patience when he's mad...

A past version of Sonic. After an accident with negative Chaos Energy acting as a conductor to Dark Gaia's Essence, Classic Sonic 'contracted' the Werehog form from his older counterpart. Unlike said counterpart, however, he takes his transformation in stride and is completely unbothered by it. The circumstances for his accidental transformation were set up by his learning of Chaos Control.
