Wen-Di-Go (or more commonly: Wendigo) is a fictional monster in the Marvel Comics universe. He is based on the mythical creature of the same name. The Wendigo first appeared in the Incredible Hulk #162.
Several people have been afflicted with the curse of the Wendigo, including Paul Cartier, Georges Baptiste, Francois Lartigue, Lorenzo, Mauvais and others.
The curse is regional to the woods of Northern Canada and takes place, under the right conditions, when a person in the forests of Canada feeds on human flesh. The cannibal transforms into a superhumanly strong, nearly indestructible, fur-covered monster: the Wendigo. He or she then roams the woods eating human beings. The Wendigo has frequently fought the Hulk, Wolverine, and Alpha Flight. Paul Cartier transformed into the Wendigo, battled the Hulk, and escaped. He battled the Hulk again and encountered Wolverine, and then battled the Hulk and Wolverine; Paul Cartier was cured as college professor Georges Baptiste became the Wendigo. He later terrorized a snowbound group. He battled Wolverine, Nightcrawler, and members of Alpha Flight; the Baptiste Wendigo was captured and cured by Shaman. Fur trapper Francois Lartrigue later transformed into the Wendigo, battled the Hulk and Sasquatch, and was taken to be cured by Shaman.
One Wendigo battled the Werewolf by Night in an issue of Marvel Comics Presents. Its most frequent appearances were in the limited series Sabretooth: Open Season #1-4 where Sabretooth was hired to kill a Wendigo creature, ultimately succeeding. A few years later, a new Wendigo emerges, leading to a fight with Wolverine and She-Hulk. A local Canadian super-hero, Talisman, arrives and claims to have a magical cure for the Wendigo's condition, but S.H.I.E.L.D. agents won't let her pass until they finally confirm her identity. After a long battle, the Wendigo is defeated by a combined attack from his two opponents, and placed into SHIELD custody.
