Mewtwo is an artificial Pokémon. It is a bipedal, humanoid Pokémon with some feline features. It is primarily gray with a long, purple tail. On top of its head are two short, blunt horns, and it has purple eyes. A tube extends from the back of its skull to the top of its spine, bypassing its neck. It has a defined chest and shoulders, which resemble a breastplate. The three digits on each hand and foot have spherical tips. Its tail is thick at the base but thins before ending in a small bulb.
