Jasper Sitwell

Jasper Sitwell debuted as a by-the-book S.H.I.E.L.D. agent assigned to work alongside Nick Fury. A graduate of S.H.I.E.L.D.'s academy, the earnest young operative proved his competence through field missions, eventually rising to become one of the organization's trusted liaison officers.

Jasper Sitwell has been a fixture of Marvel's espionage world since his Silver Age debut in Strange Tales #144 in 1966, brought to life by the legendary trio of Stan Lee, Jack Kirby, and Howard Purcell. A card-carrying member of the Avengers with deep roots in the world of S.H.I.E.L.D., he's spent nearly six decades sharing pages with titans like Nick Fury, Dum Dum Dugan, and Tony Stark — as distinguished a roster of Marvel heavy-hitters as you could hope for. His appearances across Iron Man, Avengers: Earth's Mightiest Heroes II, and the classic Nick Fury and His Agents of S.H.I.E.L.D. series speak to a character woven into the very fabric of Marvel's action and intrigue landscape, with ten key issues among his 88 catalog appearances to tempt any serious collector. If you love the spy-thriller side of the Marvel Universe, Jasper Sitwell is a name worth knowing.
