King Ghidorah

you mean the one who goes Black/White when you beat him the first time, then goes OP when you beat him to about 75% of his life? that's OP at its finest. my idea of the Charizard though, would be where you just press a simple button (maybe X/Y for fittingness' sake) and Charizard turns into one of two Megas throughout the battle. I also wouldn't mind seeing a Blastoise who can go Mega, and Venusaur who can go Mega but ehhh....I'd make Charizard my most wanted.

someone should make a Charizard character that can (permanently) switch between either Mega Charizard Y or Mega Charizard X. I would, but the spriting would be simply godawful.
