Scientists created Ditto by accident, trying to clone the
legendary pokémon Mew through it’s ancient DNA. However Ditto easily
found it’s way out the labs due to it’s transform ability.
Even the most experienced Ditto can’t fully transform itself, keeping it’s characteristic features in their transformation.
Like Mew, Ditto’s inherited curiosity is drawn to human and pokémon societies, which often infiltrates just for fun.
