Indeed, the initial plan was for Alexa Lopunny to be the only survivor of an experiment done by Alexa and Alexander parents who were scientist and breeders, Lopunny was breed to be as perfect stat, IV, EV as a Lopunny could be and then the experiment was done on her. 

There would be a device implanted in her wrist and the scar hidden by her wrist fluff which would allow her to transform/Fusion with other pokemon who's DNA lived in her. So a Hounddoom would turn her into a fire/Dark type, A Syleon would turn her into a fairy type. 

She was only going to gave about 5 forms in total, I though since Mewtwo was made by technology, that it might be possible. But, I'm rethinking my plan for her Lopunny now.
