After completing Round 1 or Round 2 of all Stadium cups and the Gym Leader Castle, Mewtwo appears in the sky over the stadium. Selecting Mewtwo allows the player to engage in a battle with Mewtwo. Defeating Mewtwo's Round 1 version is the trigger to unlock Round 2, and defeating its Round 2 version unlocks hidden stickers in the Gallery.
The player can choose to use either a team selected from rental Pokémon, a team consisting of Pokémon from a connected Game Boy game, or a mix of both. The rentals the player can select from are identical to those of the Prime Cup.
The player is allowed to use all six Pokémon in their team to take down Mewtwo.
The player's final Pokémon cannot use Selfdestruct or Explosion to defeat Mewtwo.
