Ditto

Ditto (メタモン Metamon) is a -type Pokémon. Ditto are unique as their only attack is Transform. They use this attack to copy the stats (except HP), moves (only 5 power points), types, and appearance of opponent. Another reason that they are unique is that Ditto can breed with any Pokémon in a Day Care Center, regardless of its gender, except other Ditto.

Appearance
Ditto's appearance is very plain. It is a simple pinkish purple, amorphous blob, though it can be changed via Transform. A shiny Ditto is blue as opposed the normal purple. Dittos cry is also known to be the same as Poliwags cry in the game series.
