Talk:Mewtwo VS Shadow/@comment-25172038-20160703072407

You know after seeing that Mewtwo is able to Mega Evolve without the need of a trainer helping out, what other Pokémon are able to Mega Evolve without the need of a trainer like I know Rayquaza is able to Mega Evolve because it has a special organ in it's body that allows it to Mega Evolve without help from a trainer.
