Basilisk

A creature of the Modern Age, Basilisk slithered into Marvel's pages in 2011 courtesy of writer Mike Carey and artist Clay Mann — a striking debut in X-Men: Legacy #245 that dropped readers straight into the unsettling alternate-reality landscape of the Age of X. With only a handful of catalog appearances, this is a rare, enigmatic figure whose brief existence in the margins of the X-Men universe makes every page count, sharing those charged, high-stakes stories alongside heavy hitters like Ororo Munroe, Scott Summers, and Jonothon Starsmore. For collectors drawn to the stranger corners of Marvel's mutant mythology, Basilisk is exactly the kind of compact, atmospheric discovery that makes digging through a longbox so rewarding.
