Ditto rearranges its cell structure to transform itself into other shapes. However, if it tries to transform itself into something by relying on its memory, this Pokémon manages to get details wrong.
Ditto can only transform once per battle. It will retain its first transformation for the duration of the battle.
Ditto cannot be seen in the map view, because it disguises itself as few the most common Pokémon. It will only reveal itself once it has been successfully captured.
Following the conclusion of September 2018 Community Day event, players reported sightings of an undiscovered Pokémon, who was later identified as Meltan, which turned into Ditto once captured.
