Ditto

Ditto is a Normal-type Pokémon.

It is not known to evolve into or from any other Pokémon.

Biology
In its natural state, Ditto is a light-purple or pink, amorphous Pokémon with vestigial facial features. The face consists of a simple mouth and beady eyes. It also appears to have two pseudopods protruding from its body that it uses as arms. It is capable of transforming into an exact replica of any physical object, including its form and abilities. However, if Ditto tries to transform into something based on memory, it may get some of the details wrong.

Each Ditto has its own strengths and weaknesses when it comes to transforming. The anime and the TCG have shown that occasionally Ditto cannot change its face. It will also be unable to remain in a transformed state if it starts laughing. While its transformation ability allows it to get along with almost anything, it does not get along with its own kind. When two Ditto meet in the wild, they will attempt to transform into each other. It transforms into a rock when sleeping to avoid an attack. Ditto is never far from civilization or people. Ditto is the only Pokémon capable of using the Metal Powder and Quick Powder items.
