Adventure explodes into action with the debut of Mewtwo, a bioengineered Pokmon created from the DNA of Mew, one of the rarest of all Pokmon. After escaping from the lab where it was created, Mewtwo is determined to prove its own superiority. It lures a number of talented Trainers into a Pokmon battle like no other-and of course, Ash and his friends are happy to accept the challenge!
