Shadow Mewtwo is one of two unlockable fighters in Pokkén Tournament (the other being Mewtwo) and an alternate form of Mewtwo, created when it absorbed the energy of the Shadow Synergy Stone. It can be unlocked by beating the Chroma League or by using the Shadow Mewtwo amiibo Card, a special card distributed in the first run of Pokkén Tournament. It made its debut in Pokkén Tournament, meaning it has no type or Pokémon classification. However, in the DX version and the Arcade version of Pokkén Tournament, it is unlockable as a starter Pokémon.
