Ditto

Ditto (Japanese: メタモン Metamon), is a -type Pokémon introduced in Generation I. Ditto is a unique Pokémon because it can breed with any Pokémon in a Day Care Center regardless of its gender, except for another Ditto, Legendary Pokémon (except for Manaphy and Phione), Unown, Nidoqueen, Nidorina, and Baby Pokémon.

Physiology
Ditto's appearance is very plain. It is a simple, pinkish-purple, amorphous blob, with two, small dots as eyes and a long, curved mouth. Though its appearance can be changed via Transform. A shiny Ditto is blue, as opposed to the normal purple.

Trivia

 * In Generation IV, it's possible for Ditto to learn copied moves permanently by transforming into a Pokémon which knows Sketch, such as Smeargle.
 * A battle between two Ditto would be perpetual, as the only move that they know is Transform. The reason that this occurs is when one Ditto uses Transform, it will restore the PP on its own move, thus allowing it to Transform into the other Ditto forever. This is possibly the reason why no Trainers in any main series game have a Ditto in their party, in case the player has one.
 * Ditto's cry is known to be the same as Poliwag's in the game series.
 * Ditto used to be the only non-legendary Pokémon that can transform into any other Pokémon, up until Zorua and Zoroark were introduced in Generation V.
 * Ditto is one of the few Pokémon whose name is an actual word, along with Gloom, Electrode, Golem, Slowpoke and Persian, among others.
 * Ditto's dictionary definition is "to duplicate".
 * In Pokémon Red, Ditto is found in the Pokémon Mansion, which is the lab where Mewtwo's experimentation was being done.
 * Ditto has its own Japanese song on the Japanese Pokemon Youtube Channel. Two versions can be seen here and here.
 * Ditto is one of the few Pokémon with perfectly balanced stats (all of its stats are 48).
 * Ditto is one of the 16 Pokemon to be made into a puppet in Japan.
 * Strangely, Ditto is the only Pokémon with its own Egg group (Ditto). This also makes it the only Pokemon with a single Egg Group that is unique.
