Ok, here is the best gimmick which I can think of: MIMIC.
He will not have his own gear. Maximum white paint on the face like Sting (and that is debatable too). He will enter the ring as the opposite of his opponents. For example: against the Undertaker our Mimic will be the Angel-like creature. Against Gunther he will be french. Against Stone Cold - leftist from California etc. Against jobbers you don’t have to worry about it and just wear white or dark colors depending on the role of the opponent. And the most interesting thing is that if MIMIC wins, then the loser will have to take his heel/face persona.
How would you rate it /pw/?
