RatBoy is normally of male origin but this is quite often in dispute within the field of parahuman studies.

A hybrid of the black rat (Rattus rattus) and some semblance of a human being, RatBoy gains his name through his ability to scurry up any old drain pipe with vigour, voluntariness and without remorse. RatBoy is a rare bread but yet distinctive if sighted in its natural habitat - namely dark corners of bars, clubs and supermarkets. A small beady, yet twinkle eyed creature that can sniff out its prey from vast distances. A smooth talker and schmoozer who's had the cognitive or emotional experience of guilt bred out of them.
'Prey': "I met a really nice boy the other night - he stayed, fucked me senseless - despite his tiny penis it was awesome - but he hasn't called. I feel so used!

Friend: "What a RatBoy!!"
