Ditto, Smashpedia

For the term used to define matches where both players choose the same character, see Ditto match. Ditto (メタモン, Metamon in Japan), is a fictional creature in the Pokémon media franchise. Ditto is a Pokémon that was removed from Super Smash Bros. Melee just prior to its release. Its supposed purpose was to transform into AI copy of the user's character, which would aid them in battle. However, processing problems forced its removal. It can be accessed using special software such as Action Replay
