Wonder Wart-Hog (the "Hog of Steel") is an underground comic book character, a porcine parody of Superman, created by Gilbert Shelton and first published in 1962. Over the years, Shelton has worked on the strip in collaboration with various writers and artists, including fellow UT Austin alums Tony Bell, Bill Killeen, and Joe E. Brown Jr. Gilbert's humor occasionally crosses the line into violence of a sexual nature, but the emphasis is more on the absurdity of the situation than the act itself.
