Neutron

Neutron is a powerful alien warrior who first appeared as a member of the Shi'ar Imperial Guard, the elite military corps serving the Shi'ar Empire. Encountered by the X-Men during a fateful clash in deep space, he serves as one of the Guard's formidable frontline combatants.

Born into the cosmic grandeur of Chris Claremont and Dave Cockrum's Bronze Age imagination, Neutron made their debut in The X-Men #107 in 1977 — one of the most celebrated eras in Marvel history — arriving as part of the sprawling, star-spanning world of the Shi'ar Imperial Guard. Over nearly five decades, this cosmic warrior has kept extraordinary company, sharing adventures with powerhouses like Gladiator, Starbolt, and Oracle across the pages of Uncanny X-Men, Quasar, and Inhumans. With affiliations spanning the Imperial Guard, the Shi'ar, the Starjammers, and even the X-Men themselves, Neutron occupies a fascinating crossroads of Marvel's cosmic and mutant mythologies. Two key-issue appearances and 22 catalog entries make this a rewarding deep-cut discovery for any collector who loves the outer reaches of the Marvel Universe.
