Nightcat

A Marvel creation of the early '90s Copper Age, Nightcat made her entrance in the pages of Nick Fury, Agent of S.H.I.E.L.D. #20 (1991), brought to life by writer D. G. Chichester and artist Jackson Guice. She debuted in rarefied company — sharing those pages with espionage heavyweights like Colonel Nick Fury, Countess Valentina Allegra de Fontaine, and even the Red Skull himself — which makes for quite the introduction. Her catalog footprint is small and genuinely rare, the kind of fleeting Marvel curiosity that serious collectors love to track down, a brief but vivid flash of early-'90s energy worth seeking out precisely because so few readers know she exists.
