Moira MacTaggert's son, an omega-level reality warper whose powers burn through host bodies at a terrifying rate. Proteus's rampage through Edinburgh was one of the most harrowing early X-Men stories, forcing the team to confront a threat they couldn't simply overpower. His resurrection during the Krakoan era raised profound questions about the ethics of the resurrection protocols.

Fan Sentiment

Proteus remains one of the X-Men's most unsettling villains, a reality-warping mutant whose tragic origins as Moira MacTaggert's son add emotional weight to his devastating power set. The original Claremont run from *Uncanny X-Men* #125-128 is widely regarded as a horror-tinged masterpiece that showcases both Moira's fierce determination and the genuine terror Proteus inflicts on the team. His Omega-level reality manipulation and body-hopping abilities make him a perennial favorite for stories exploring the darkest possibilities of mutation.
