S.H.I.E.L.D.

Created by Stan Lee and Jack Kirby in Strange Tales #135 (Aug. 1965), it often deals with paranormal and superhuman threats to international security.

The acronym originally stood for Supreme Headquarters, International Espionage and Law-Enforcement Division. It was changed in 1991 to Strategic Hazard Intervention Espionage Logistics Directorate. Within the various films set in the Marvel Cinematic Universe, as well as multiple animated, live-action television series, and video games, the backronym stands for Strategic Homeland Intervention, Enforcement and Logistics Division.
