Jhonen Vasquez
Creator of "Johnny the Homicidal Maniac" & "Invader Zim"

Fun Fact: Jhonen is surpisingly friendly and not at all scary... except to my wife, who didn't expect to find him (or anyone, really) amongst the t-shirt boxes at the SLG booth at Comic Con a few years back. (He was taking a much needed fan-break at the time.)
