Prism

Prism is a mutant who first clashed with X-Factor in the pages of their early adventures. A member of the Marauders, the ruthless band of killers assembled by Mister Sinister, he possesses crystalline abilities that make him a formidable threat.

Prism has been a fixture of Marvel's mutant universe since 1986, when Louise Simonson and Walter Simonson introduced this Marauders member in the pages of X-Factor — right in the thick of the Copper Age's most turbulent X-Men storytelling. Affiliated with both the Marauders and the X-Men over the years, Prism has kept genuinely dangerous company, sharing pages with the likes of Harpoon, Scalphunter, and Wolverine across Uncanny X-Men, X-Factor, and X-Men. With nearly four decades of appearances and a key-issue debut to their name, Prism is one of those characters whose presence signals that the stakes have been raised — a collector's footnote who carries real weight in Marvel mutant history.
