Dr. robuttnik

Dr. Robuttnik is the original Dr. Aggmen. The part of his last name "BUTT" comes from his unforgiving, wide butt he uses to squash the ignorant. He was the real Dr. who hated Sanic but then he got removed from the spotlight and got turned into Dr. Aggmen. Then his old army thought with their computer brains and gave him his position back.

Since, Dr. Aggmen, Matel Sanic and others have worked for him. All in all, he is also smarter than Aggmen.

He's part of the I Suck Society.
