Once Sonic defeats one of his werebeast friends they turn back to normal, or at least retain sanity and only return to normal during day. But Sonic will be the only playable character.

Because Amy with a pwoerful hammer, Knuckles turning into a mountain of a monster and I really dunno about Tails maybe a bit too much for gameplay.
