The Transform Pokemon
Height: 1 foot
Weight: 8.8 pounds
Ditto is an amorphous Pokemon that is capable of transforming into an exact replica of any physical object, and can copy its form and abilities. However, if it transforms based on memory, it may get some of the details wrong. The anime has shown that some individuals can have trouble with changing their face when transforming, and it can't stay transformed if it starts laughing. While its transformation ability allows it to get along with almost anything, it ironically doesn't get along with others of its kind; when two Ditto meet in the wild, they will try to transform into each other. When sleeping, the Ditto turns into a rock to avoid an attack.
