Adapting to an Unwanted Life (Pokemon TF)

A professional biologist uses his knowledge of the adaptative nature of Earth's animals to fight against Pokemon of any kind. He'll need every advantage he can get when he's no longer a human and now has the unfamiliar form of a Weavile. He must get used to it quickly and find the being who did this to him or he'll be stuck like this forever. (Weavile TF). Warning: dark.
