A clone made from Mew’s DNA, Mewtwo was enraged at his existence as nothing but a tool for fighting. In his anger, he destroyed the Team Rocket base and established a base in the middle of the ocean, inviting strong trainers to come and face his army of super clones. When Ash and company are invited to the island, Mewtwo’s intentions become clear and it’s up to them, the other trainers, and all the original Pokemon, including Mew, to stop him. The battle of Pokemon vs. clone begins!
