phst havent you ever heard of hedgehogs turning into werewolfs

and there could be many valid reasons for this.

Dr. Robotnik developes a chemical the turns all the little creatures he captured into werewolfs to fight sonic and sonic accadentaly gets infected himself.

then he turns in and out of werewolf form

this Idea could work if they were trying to make a more of a sonic game with better battles then just hey lets jump on this guy and jump on that guy and roll

this werewolf would be a bit slower so controls for fighting could be more finely tuned.

just an idea for why they might do such a thing
