I've long been a fan of Doug TenNapel's graphic novels, like Creature Tech, Earthboy Jacobus and the more recent Ghostopolis. My only complaint is the long wait between them. If you're impatient like I am, here's the cure -- TenNapel has launched a new webcomic, Ratfist, which I believe is his first foray into the world of superheroes. There are only two pages up right now, as it launched yesterday, but his plans are to update every weekday.
