Ditto (Japanese: メタモン Metamon) is a Normal-type Pokémon introduced in Generation I. It is not known to evolve into or from any other Pokémon. Ditto is well known for its unique ability to breed with any Pokémon other than the Pokémon in the No Eggs Discovered group and other Ditto, including some gender-unknown Pokémon, to produce Eggs of the other's species. Ditto is also seen sometimes transforming into Humans. Ditto (in human form) is the main protagonist of the upcoming Pokémon Pokopia.
