Kukulcán

A figure rooted in the earliest days of Marvel's mutant mythology, Kukulcán made their mark in 1966's The X-Men #25 — a Silver Age debut in the very title that would go on to become one of comics' most celebrated franchises. Sharing those formative pages with Charles Xavier, Cyclops, and Iceman places this character at the heart of Marvel history, rubbing shoulders with icons before they were icons. Though appearances in the catalog are rare, that Silver Age pedigree and the company kept make Kukulcán a genuine piece of Marvel's foundational era — the kind of deep-cut discovery that reminds collectors just how rich and strange those early X-Men adventures truly were.
