Cerberus

Cerberus is Marvel's depiction of the legendary three-headed hound from Greek mythology, serving as the fearsome guardian of the underworld and a recurring adversary or obstacle in stories featuring mythological heroes such as Hercules.

Born in the Bronze Age pages of Spider-Man Comics Weekly #64 in 1974 — courtesy of the legendary Stan Lee and Steve Ditko — Cerberus is a Marvel figure who has prowled the edges of some genuinely mythic company: Hercules, Thor, the Hulk, and Doctor Strange have all shared adventures in the same issues. With appearances stretching across an impressive 43 years and a presence felt across titles like Incredible Hercules and Fantastic Four, this character occupies a fascinatingly durable niche in the Marvel cosmos. Fourteen catalog appearances may be a selective footprint, but one of them carries key-issue status — reason enough for any dedicated collector to take notice.
