Yeti

A hulking mutant operative who ran with an early, pre-X-Men underground network alongside Logan, Yeti was part of a rough-edged crew of powered individuals banding together before Xavier's school ever existed.

A hulking presence from the earliest days of Marvel's mutant underground, Yeti debuted in 2012's First X-Men #2, brought to life by the legendary Neal Adams and Christos Gage in a story that reached back to explore the roots of the X-Men mythos. This Modern Age creation shares the page with a compelling cast — including Logan and characters like Lyle Doome, Bomb, and Holly Bright — suggesting a world crackling with danger and raw mutant energy. With only five catalog appearances concentrated in the First X-Men limited series, Yeti is a rare, tightly focused figure rather than a sprawling franchise player, which gives completionists and lore-hunters all the more reason to track down every panel. If you love digging into the corners of Marvel's mutant history, this is exactly the kind of discovery that makes collecting so rewarding.
