As a Poké Ball Pokémon
When Manaphy appears from its Poké Ball, it uses its signature move Heart Swap, temporarily swapping the bodies of 2 players. This can be dodged via a properly timed air dodge. During the heart swap, the players keep their own damage and stocks, and self-destruction causes the player to lose a stock, not the opponent. The only thing that is kept with the body is the ownership of Poké Ball Pokémon and characters from Assist Trophies.

Two players need to be close to Manaphy in order for the Heart Swap to take effect. In the very unlikely case of two Manaphy appearing together, the first Manaphy's Heart Swap is canceled when the second one is activated.

Once the second player is KO'd, they will reappear as their original character.
