Metaform Mutant Animals(or another way to do Were-creatures):

History: REALLY fuzzy. Some claim to be from a dimension that was decimated by a Nulcear war. In the aftermath animals mutated, became sentient and tried to take over the world as it's new 'owners'. In the fight for control, the mutant animals figured out how to CREATE mutant animals and from there went to Metaform Mutant Animals. Others say the same thing, except science didn't create them...magic did. Still others claim they are products of Splugorth, or some other alien empire's, bio-wizard experiments. And stillsome claim to be Lonestar experiments!! Amazingly...Metaform Mutant Animals have been on Rifts Earth for some time...so many stories of where they are from are at least two generations old.

Ok...for these you NEED TMNT.Decide which creature is going to be your Were-Form.
