Ghost of Mr. Hyde
I think I found my next theme I'm going to explore--Scooby Doo villains!  I was a huge fan of the show growing up, and Hanna Barbera in general.  The Ghost of Mr Hyde was a villain that I thought had a cool look. Some of the designs in the show weren't so great, but they did have a share that actually did look creepy as hell. 

I would love love love to draw a Scooby comic.  Who do I gotta bug at DC to get on that?
