I added myself (Squirtle) to the battle! We'll need a lot more people to take down Mewtwo so add all you want! You just need to code yourself, your own attack and HP.
Credit to @shadowstriker34 for most of the coding I coded my own attack and sprite ------------------------------------------------------------------------------------------There's a glitch where there's a ton of Mewtwo's Shadow Balls and they are stuck on Mewtwo's side of the screen. Like a Spiky Sheild around Mewtwo. It usually goes away after a bit. But I don't know why it happens...
