X-Factor debuted in 1986 and originally reunited the five founding members of the X-Men: Cyclops, Marvel Girl, Beast, Angel, and Iceman. Posing as mutant hunters while secretly rescuing and helping mutants in need, the team quickly became a major part of Marvel’s growing mutant line. Over the years, X-Factor evolved through numerous incarnations, each bringing a fresh perspective to the concept while maintaining its focus on mutant challenges and relationships.

Throughout its history, X-Factor has featured some of Marvel’s most compelling storytelling, blending superhero action with mystery, politics, humour, and character-driven drama. From government-backed strike teams to private investigative agencies led by Multiple Man, the series has continually reinvented itself while showcasing both iconic X-Men characters and lesser-known mutant heroes. This rich variety has made X-Factor a favourite among readers looking for stories that go beyond traditional superhero adventures.
