Mega Mewtwo Y is a Psychic-type Mega Pokémon that Mega Evolves from Mewtwo when holding a Mewtwonite Y.


When Mewtwo Mega Evolves into Mega Mewtwo Y, it becomes smaller and lighter, losing its long tail and the tube behind its neck. However, it grows a long, purple appendage with a curled tip from the back of its head that is similar to Mewtwo's tail. On its head it has two pointed, backward-curving spikes and a half-ring structure connecting to base of each and crossing over the top of its head, with empty space inside. Its eyes are now red and slightly larger. The digits on its hands and feet are now purple and more bulbous, and the middle toe is longer than the others. A bumpy ridge similar to a sternum replaces the breastplate structure on its chest, but this form is still largely smoother than the other two.
