Al Mackenzie

Stepping onto the scene in 1988 during the gripping Nick Fury vs. S.H.I.E.L.D. limited series, Al Mackenzie is a Copper Age Marvel creation born from the collaborative work of Bob Harras and Paul Neary — right in the thick of one of espionage comics' most paranoid, conspiracy-laden storylines. He moves through a world populated by heavy hitters like Colonel Nick Fury, Countess Valentina Allegra de Fontaine, and Alexander Pierce, which tells you everything about the high-stakes S.H.I.E.L.D. universe he inhabits. His appearances are compact but purposeful, the kind of supporting presence that gives a tightly wound spy thriller its texture and credibility. For collectors who love the shadowy corners of Marvel's intelligence world, Al Mackenzie is a satisfying deep-cut discovery.
