This happens in quite a few of my Fics... anyway, going by the prior Picture, this is what happens to Max in the Mewtwo Too remake of "Jirachi: Wish Maker". By this point he has found out Ash's Secret, and finds it EXTREMELY cool. A Wish he makes to Jirachi, while alone with him is to be "As cool as Ash". Of course, Jirachi takes it literally, and turns him into a Mewtwo as well.

While this surprises Max, now Maxtwo, he's not upset at all, and takes to it quite well. Ashtwo, Misty, Maxtwo, and Wally (Who found out Ash's secret when he saw Max like this and replaces Brock while in Hoenn), however, have to work to keep it a secret from May.
