Wonder Wart-Hog (the Hog of Steel) is an underground comic book character, a porcine parody of Superman, created by Gilbert Shelton and Tony Bell.
His secret identity is the mild-mannered reporter Philbert Desanex. (Occasionally, however, Shelton has depicted Wonder Wart-Hog and Desanex as two distinct individuals, with WW-H able to reside inside the reporter's body.)
