Agent L

Stepping out of the shadowy world of Marvel's espionage universe, Agent L made their debut in the Silver Age classic Nick Fury, Agent of SHIELD #4 in 1968, brought to life by Roy Thomas and Frank Springer during one of comics' most thrillingly paranoid eras of spycraft and secret organizations. With a catalog presence stretching all the way to 2015, this enigmatic figure has kept remarkably rarified company — sharing pages with the likes of Tony Stark, Gabe Jones, and the sinister Imperial Hydra across the clandestine corridors of S.H.I.E.L.D. A rare and elusive presence with only a handful of recorded appearances, Agent L is precisely the kind of deep-cut discovery that makes digging through Marvel's espionage titles so rewarding for the dedicated collector.
