Ditto's only know the move Transform, which turns Ditto into the opposing Pokémon, copying type, appearance, moves, and stats besides HP. Any moves copied are set at 5PP. Ditto can be found by using the Cloning Machine with a random chance instead of Mewtwo. It can also spawn naturally, but extremely rarely. Unlike Legendaries, it doesn't have a message when Ditto spawns.
Because of the way it can transform into any other pokemon, it can breed with any pokemon. Ditto is highly saught after for this reason.
