Kastyx

A creature of the early '90s Marvel cosmos, Kastyx made their debut in Marvel Comics Presents #93 in 1991 — that gloriously jam-packed anthology series where Marvel loved to unleash the weird and the cosmic. With a catalog presence stretching all the way to 2017, this is a character whose reach quietly outlasted the Copper Age that spawned them. Kastyx keeps extraordinary company: Nova, Ghost Rider, Frankie Raye, and Logan have all shared pages in these adventures, placing this character firmly in Marvel's wilder, more expansive corners. Rare in appearance but persistent across decades, Kastyx is exactly the kind of deep-cut discovery that makes digging through Marvel Comics Presents back issues such a rewarding hunt.
