Ditto

Ditto (Japanese: 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 the appearance of the 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.

Evolution
Ditto does not evolve.

Trivia

 * Ditto's cry is similar to Poliwag's.
 * Ditto makes an appearance in Super Smash Bros. Melee.
 * In Generation IV, it's possible, by glitch, for Ditto to learn copied moves permanently by transforming into a Pokémon which knows Rage.
 * If a Ditto battles a Ditto, they would both keep on using Transform until one of them eventually runs out of PP and uses Struggle.
 * Ditto can be only paralyzed when in the transform mode.
 * Ditto as a dictionary meaning means to dupliacte/copy.
 * Ditto is the same colour and weigh the same as mew also mew and ditto are the only pokémon that can use every move including transform so it is believed that ditto is a failed experiment to recreate mew

In the Anime
Ditto's first appeance was on IL037 where a Trainer named Duplica owned a Ditto.
