Bio
Mewtwo was the result of a horrific DNA scientific experiment by Team Rocket's top scientist. Designed from an embryo of a pregnant Mew, Mewtwo was altered to become the world's strongest Pokémon; however, Mewtwo turned on it's creators and murdered everyone in the lab, making it's escape. As a living creature, Mewtwo has a savage heart, and because of it's altered genetics, all it can think about is defeating anything in it's way; regardless of Pokémon or human.

One Minute Melee
Mewtwo appeared in the 11th episode of One Minute Melee, where fought against Frieza from Dragon Ball Z and lost.
