MEWTWO

Mewtwo
The complex Mewtwo was created in a lab, using Mew's DNA. A very smart and powerful Psychic-type Pokemon, Mewtwo will do whatever it thinks is right- regardless of who gets hurt along the way.

DNA of Mew's
Its DNA is almost the same as Mew, and it has Psychic-type attacks, but Mewtwo and Mew are very different. Mewtwo was created in a lab for the sole purpose of winning battles. It lives in hiding, concentrating on raising its levels so that no one can beat it.
