The X-Men #104
The X-Men #104 is a landmark Bronze Age chapter in the Claremont–Cockrum run, packing an extraordinary number of firsts into a single 17-page story: the debut of Muir Island as Moira MacTaggert's secret mutant-research facility, the first cameo appearance of the Starjammers (Corsair and Ch'od) — the cosmic-pirate team who would anchor the X-Men's entire Shi'ar storyline — and the first on-panel mention of the entity 'Mutant X,' whose name on a containment-cell door foreshadows the character who becomes Proteus nearly twenty issues later. Magneto's dramatic restoration to adulthood also carries lasting structural weight: Erik the Red's ray doesn't simply reverse the infantilisation that occurred in Defenders #16 — later stories imply it actually de-aged Magneto into a younger, more powerful adult, the retroactive explanation for how a Holocaust survivor could credibly continue his schemes for decades to come. Dave Cockrum's cover, a knowing rearrangement of Jack Kirby's very first X-Men #1 composition, signals the creative team's confidence that this relaunched title had fully earned its place in Marvel's pantheon.

Written by Chris Claremont and pencilled by Dave Cockrum with inks by Sam Grainger, the issue was edited by Archie Goodwin and carried a cover date of April 1977, placing it on stands in January of that year — before Star Wars had been released, which is relevant because Cockrum had designed the Starjammers as a space-pirate ensemble he originally intended to anchor their own series. When Marvel repeatedly told him that both try-out venues, Marvel Spotlight and Marvel Premiere, were booked solid for two years, Cockrum brought the concept directly to Claremont, who agreed to fold the characters into X-Men; the creative pair then deliberately wrote Corsair as Cyclops's long-lost father to give the Starjammers narrative hooks that would justify their recurring presence in the book. The Dragonfly subplot seeded here — in which the imprisoned Ani-Men member is noted to have escaped — existed because Cockrum was quietly developing an all-female superhero team that would have included both Dragonfly and Storm, a project that was ultimately shelved before reaching print.
Trivia · 8 facts
- First appearance (cameo) of the Starjammers: Corsair (Christopher Summers) and Ch'od appear aboard the starship Starjammer in a brief but named scene — their first comics appearance anywhere, created by Dave Cockrum.
- First appearance of Muir Island, Moira MacTaggert's mutant-research facility off the northwest coast of Scotland, which becomes one of the series' most important recurring locations.
- First mention of 'Mutant X' — a name glimpsed on a glowing containment cell door as Magneto departs Muir Island; the entity behind the door is later revealed to be Proteus (Kevin MacTaggert), who first fully appears in Uncanny X-Men #125 (1979).
- Magneto is restored to adulthood by Erik the Red using an unspecified aging ray, reversing his infantilisation from Defenders #16; later stories establish that the process also de-aged and power-upgraded him, explaining his continued menace across subsequent decades.
- Jamie Madrox (Multiple Man) makes his first appearance in an X-Men comic, having previously debuted in Giant-Size Fantastic Four #4; here he serves as Moira's research assistant on Muir Island.
- Dave Cockrum's cover is a deliberate homage to the Jack Kirby cover of X-Men #1 (1963), repositioning Cyclops and a newly adult Magneto in an updated echo of the original composition.
- Written by Chris Claremont, pencilled by Dave Cockrum, inked by Sam Grainger, coloured by Andy Yanchus, lettered by Bruce Patterson, and edited by Archie Goodwin; cover-dated April 1977, on sale January 1977.
