Metal Overlord
Smash Hero
Yep, my only possible nitpick with that is he shouldn't be able to talk in his taunts; Classic Sonic can't talk, only Modern Sonic. This'll probably be one of the few overlooked things in Smash 4, though...Classic Sonic totally needs to be in it as well, it would go perfect along with Green Hill Zone.
Also, I want to add that Dr. Mario should have 2 of Mario's moves changed for him: obviously, his neutral B should be changed to Megavitamins, but his down B shouldn't be the F.L.U.D.D, either; he should have the Dr. Tornado as his down B. Well, really, both of them need to have the Tornado back, the F.L.U.D.D is such a waste in Brawl lol.
