Constantine

His earliest memory was growing up in the middle of a mostly uninhabited desert with the odd van full of people passing thru it. He's a chupacabra that means he lives mostly off of the blood of living creatures, and this includes human beings. He isn't all that keen on chasing down cars, so he mostly sticks to goats and whatever else he can catch. He can see perfectly well in the dark. Recently he's come upon a chicken farm owned by a handsome guy around his age. He steals chickens and mostly evades capture (except he's kinda hoping he doesn't).
