's character whenever he goes near a Chaos Emerald. This state was heavily influenced from all the years he's been bullied and humiliated upon, foolishly bottling up his problems and hoping that it'll all just go away. Unfortunately, ANY kind of bottle will eventually break soon as it reaches its capacity, unleashing all kinds of hell in its mess.
No special abilities or the likes are gained during his "enraged" state, but he's certainly a danger to anyone around him and himself. He'll focus on the person(s) who pushed him too far with little care towards other getting in his way, and won't even stop attacking them until he certain they've been "punished" enough.
Pretty much the biggest reason why he's highly cautious around people. Last thing he ever wants to meet one who wants to anger the poor cabbit...
