Forgetmenot

Forgetmenot is a mutant X-Men operative whose power is a cruel irony: everyone forgets he exists the moment they look away from him, making him effectively invisible to allies and enemies alike despite his constant, loyal service.

Few characters in Marvel's Modern Age embody a more poignant concept than Forgetmenot, who debuted in Simon Spurrier and Tan Eng Huat's X-Force #10 in 2014 — a genuinely unforgettable introduction built around the cruel irony of being perpetually forgotten. Over a run stretching from that debut into the 2020s, this character has kept remarkable company, sharing pages with luminaries like Psylocke, Doctor Nemesis, and Charles Xavier himself across X-Force and Legion of X. The relatively modest appearance count only deepens the mystique — there's something fitting, even beautifully meta, about a character whose very nature seems to explain their elusive presence in the catalog. If you love the stranger, more philosophical corners of the X-universe that Spurrier has always championed, Forgetmenot is absolutely worth seeking out.
