Behold the Mod Pokemon, using his favorite ability, “Transform.”
okay so is it that you’re a Mew who uses Ditto’s ability, or a Ditto that uses transform ?
Maybe Transform is Mew’s ability, and Ditto stole it?
Entirely possible since ditto are failed mew clones and mews have shown the ability to transform in the show, movies and games. They can transform without a reference unlike dittos.
