Mewtwo Ball

The Mewtwo Ball is a specialised Pokéball used by Mewtwo in order to capture the Pokémon whose trainers were selected to go to New Island. Its main purpose is to allow the captured Pokémon to become cloned for Mewtwo's army, in order to fight against the originals. The Mewtwo Ball can also capture Pokémon already stored within ordinary Pokéballs, and are able to pursue Pokémon as if flying. Once the cloning process is complete, the Mewtwo Balls release the captured Pokémon.
