Wonder Wart-Hog (the "Hog of Steel") is an underground comic book character, a porcine parody of Superman, created by American cartoonist Gilbert Shelton and first published in 1962.

[1] 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.

Wonder Wart-Hog's rogues gallery includes "Super-Fool, Super-Hypnotist, the Masked Meanie, Super-Patriot, the Plastic Man, the Granny of Gruntville, the Bad Brainbender, Pie Man, the International Order of Bomb-Flinging Fiends, the Amazing Meanie Fuel, the Famous Rushin' Bear, Evil Weevil, the Mafia, the Zymotic Zookeeper, Smiling Sergeant Death, the Elusive Chimerical Chameleon, and the Pigs from Uranus, among others".

[2] The zany showdowns involve contests such as backward motorcycle races (who can go the slowest) or exposing some villain running a fraud scheme such as comet insurance.

[3] 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.

The first ongoing publication of Wonder Wart-Hog was in Drag Cartoons issues #25-49 (1966–1968); several of those also featured another Shelton strip called Bull O'Fuzz.

In 1968, while still living in Austin, Texas, Gilbert self-published Feds 'N' Heads, which featured Wonder Wart-Hog as well as Shelton's other creation, The Fabulous Furry Freak Brothers.

Feds 'N' Heads was later reprinted multiple times by the Bay Area underground publisher Print Mint.

By 1969, Shelton had moved to San Francisco, and that year he co-founded the underground publisher Rip Off Press with three friends from Texas: fellow cartoonist Jack Jackson, Fred Todd, and Dave Moriaty.

These three issues reprint all of the Rip Off stories (but not all of the covers and single page appearances) except for the following: In addition, the story from Radical America Komiks was reprinted in Wonder Wart-Hog and the Nurds of November, a trade paperback published by Rip Off Press in 1980, which included a large collection of earlier material.
