Doom

Debuting in 1974's FOOM Magazine #4 — a Bronze Age Marvel collector's artifact brought to life by the legendary Steranko — Doom has carved out a quietly fascinating corner of the Marvel universe across more than five decades of publication. With appearances spanning Marvel Age, Spider-Man 2099, and Spider-Man 2099 Classic, this character keeps genuinely compelling company, sharing pages with the likes of Spider-Man, Miguel O'Hara, the Punisher, and Victor Von Doom himself. That debut issue carries key-issue status, making it a meaningful find for any serious Bronze Age hunter, and the sheer breadth of this character's publishing history — stretching from 1974 all the way to 2025 — speaks to a staying power well worth investigating.
