The demonic Wat, from the Real Ghostbusters. This is one of my all time favorite monsters, I dunno why . . . she just is. Had sooooo much fun drawing in the tons of warty detail.
The first sketch I drew had Wat looking more muscular and sleek, but even though it's a shapeshifter, it can only turn into an elderly female human. I thought, what if she elderly herself? She kind of resembles a mutated, diseased tyrannosaur, maybe she's a 70-odd million years old. So I gave her scrawny shanks, a bit of upper-arm flab, a potbelly, a goiterous dewlap, a hint of a hunchback, nasty old plaque-covered fangs and overgrown nails.
