The Pokémon Company began streaming a video to tease "a newly discovered Pokémon in Pokémon X and Pokémon Y that bears an intriguing resemblance to the Legendary Mewtwo" on Saturday. Like Mewtwo, this new Pokémon has "a light-purple body and piercing, powerful eyes."
The new Pokémon will debut in the Pokémon X and Pokémon Y games on the Nintendo 3DS worldwide this October.
