Mewtwo

Mewtwo is the greaTtest Psychic Pokémon from the world of the same name, and one of the strongest of all. He is the first and one of the few that was created by science as an attempt to clone a better Mew. A project funded by Team Rocket’s leader Giovanni with which to rule the world. But Mewtwo’s intelligence and strength were too great to control, and Mewtwo attempted to destroy the world from the manipulation. Were it not for willing sacrifice, he would’ve succeeded by psychically making a storm strong enough to wipe out all life. He has proven capable of inhibiting the abilities of an army of Pokémon, forcing his will upon others for mind control, and wiping out the memories of dozens to erase his very existence from their minds.
