Sack

Sack is a Marvel mutant who first appeared during the mid-1990s X-Men era. A minor mutant character, he is associated with the broader X-Men corner of the Marvel universe, appearing in stories involving the 198 — a group of mutants who retained their powers after a major decimation event.

Debuting in the pages of The Uncanny X-Men #323 in 1995, Sack is a Marvel mutant who arrived during one of comics' most turbulent and creative eras, brought to life by the acclaimed team of Scott Lobdell and Bryan Hitch. As a card-carrying X-Man, this character keeps extraordinary company — sharing adventures with luminaries like Beast, Emma Frost, Logan, and Ororo Munroe across landmark series including Civil War: X-Men and X-Men: The 198. With appearances spanning nearly two decades and at least one collector-recognized key issue to their name, Sack may not be the most prominent face in the X-roster, but for fans who love the deep cuts and hidden gems of the mutant corner of the Marvel Universe, that's precisely the appeal.
