Wendigo
In Algonquian folklore, the wendigo () or windigo is a mythical man-eating monster or evil spirit native to the northern forests of the Atlantic Coast and Great Lakes Region of the United States and Canada. The wendigo may appear as a monster with some characteristics of a human or as a spirit who has possessed a human being and made them become monstrous. It is historically associated with murder, insatiable greed, and the cultural taboos against such behaviours.
Weapon H
While resisting the change upon joining Roxxon's archaeological expedition to find a Wendigo, Clayton assumed his Weapon H form and saved Roxxon scientist Dr. Ella Stirling from an Ur-Wendigo as Roxxon takes an interest in Weapon H. Though this also attracted the attention of Doctor Strange who plans to deal with Weapon H and the Ur-Wendigo. While Weapon H is getting Dr. Stirling to safety, the Ur-Wendigo caught up to Weapon H and took a bite out of his skin causing the Ur-Wendigo to get larger. Doctor Strange showed up to help fight the Ur-Wendigo where his magic attacks have no effect on the Ur-Wendigo. Using Doctor Strange's Axe of Angarruumus, Weapon H went inside the Ur-Wendigo and killed it from within.
