Based on the nose and the eyebrows I’d say all of these are portraits of Beastie. I’m not sure what’s up with long haired versions. Disguises perhaps?

Okay, not everything here is a portrait of Beastie. The weird thing in the middle of the page is a marionette wasp, an other dimensional predator that implants its eggs in human beings as part of its breeding cycle. It’s obviously not a very attractive creature so, in order to get close enough to a human to implant its eggs, it disguises itself as a human.
