Plague

Plague is a member of the Morlocks, the underground community of mutant outcasts living in the sewers beneath Manhattan. Her mutant ability allows her to transmit deadly diseases through touch, making her one of the more dangerous members of that society.

Born in the shadows beneath Manhattan, Plague made her mark on Marvel's Bronze Age when Chris Claremont and Paul Smith introduced her in the landmark Uncanny X-Men #169 — a debut that collectors still recognize as a key issue to this day. She emerged as part of the Morlocks, the underground community of outcasts that would reshape X-Men lore, and her appearances across Uncanny X-Men, X-Men Classic, and X-Factor put her in striking company alongside Storm, Angel, and Caliban. Though her catalog footprint is compact, the era she represents — that rich, character-dense Claremont period of the early-to-mid '80s — gives even a handful of appearances real weight. For collectors chasing the full tapestry of Morlock history, Plague is a name worth knowing.
