Beast, from Rotten School, definitely went through a nice exploratory. While he turned out looking like the one below, we went through a range of possible looks.
He was described as dog-like, always wearing a dog collar, with an optional leash attached. Starting with a bit of a hunched-over look, we then put him up on two feet. He also needed to be hairy, so we tossed a bunch of nasty bed-hair types on them. I had one I liked where we never saw his eyes...but in the end, we bulked him up and went with the one above.
