Mewtwo is a man made pokemon iirc, made from the genes of a pokemon called Mew, hence the name MewTWO. (I didn't get that until recently...) In one of the Pokemon movies he made dupes of all the pokemon and then they fought and then Ash turned to stone and then Pikachu cried on him and everything turned out okay.
