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.
Jamie Madrox
Jamie Madrox is referenced in the appendix of issue #6 of the 1997 miniseries "Earth X": "Multiple Man. Jaime Madrox lives in every city of the earth. He's sort of a street informer who peddles himself on his ability to convey anything going on to anyone – should they pay high enough". Madrox would later appear in the sequel series "Universe X" in the "Beasts" special, in which Jamie's hunger for meat during a food shortage causes him to eat one of his own duplicates. This action brings the curse of Wendigo upon Jamie. Interacting with his own mutation, the curse created a pack of Wendigo. This pack follows the combined forces of Wakanda and the X-Men to the Savage Land. In a last stand against the Wendigo, the combined forces of Black Panther, the X-Men, the Ani-Men and the Hulk defeat the Wendigo in a circle of fire. Jaime then reverts to normal and confesses his cannibalism before dying. It is not specified if the Jamie in this book is the original Jamie or a duplicate.
