S.H.I.E.L.D. is a Marvel Comics fictional advanced counterterrorism and intelligence agency charged with investigating and neutralizing paranormal and superhuman threats for global security. It was created by Stan Lee and Jack Kirby in Strange Tales #135 (August 1965) and appeared throughout the publisher's entire comic book line. The agency and its traditional executive director, Nick Fury, have also starred in their own series and miniseries sporadically since that time, most notably during a late-1960s run by writer-artist Jim Steranko.

Three official continuity versions of S.H.I.E.L.D. are listed here: the traditional version in mainstream Marvel Universe continuity, followed by the alternate reality version published under the Ultimate Marvel imprint, as well as the Marvel Cinematic Universe version. Amalgam Comics, a joint venture between Marvel and DC Comics, have their own version of S.H.I.E.L.D. that combines characters from both publishers.

Marvel Cinematic Universe S.H.I.E.L.D.

In the Marvel Cinematic Universe, S.H.I.E.L.D. was founded by Strategic Scientific Reserve Agent Peggy Carter, along with Howard Stark in 1965. Howard Stark is the deceased father to Tony Stark which is why Iron Man has supported the group, until it was revealed in Captain America: The Winter Soldier, that S.H.I.E.L.D. was infiltrated by Hydra since its formation. When Hydra emerges in 2014, S.H.I.E.L.D. is labeled as a terrorist organization while most of its non-Hydra members leave S.H.I.E.L.D. to work the private sector or go off the grid. In the second season of the television series Agents of S.H.I.E.L.D., after Nick Fury charges him with rebuilding the organization, Phil Coulson manages to win back the American government's trust as S.H.I.E.L.D. now works behind the scenes. S.H.I.E.L.D. is currently defunct after the destruction of The Playground, S.H.I.E.L.D.'s HQ and the mysterious disappearance of Former Director Philip J Coulson.
