Doctor Doom

There's something wonderfully layered about a character who shares their corner of the Marvel universe with heavyweights like the Punisher, Thor, and Kristoff Vernard — this Doctor Doom, who made their debut in the pages of Fantastic Four #278 in 1985 under the pen of the legendary John Byrne, is a Bronze Age creation with a presence that has persisted across an impressive 36 years of Marvel publishing. A card-carrying member of the Fantastic Four, this character turns up across a varied slate of titles — from Fantastic Four to The Punisher and Essential Punisher — suggesting a storytelling reach that extends well beyond any single corner of the Marvel universe. With at least one key-issue appearance to their name, collectors have reason to pay attention, and any character who has endured from the mid-1980s through 2021 clearly has staying power worth celebrating.
