Son of World War I pilot Jack Fury, Nick Fury became a legendary hero in the early years of World War II, taking missions into Europe alongside his friend Red Hargrove, under the command of Lt. Samuel Sawyer. During a mission in Holland, Fury, Hargrove and Sawyer befriended circus strongman Timothy “Dum-Dum” Dugan who became a close friend. Hargrove was killed in the attack on Pearl Harbor that led the US to officially enter the war on December 7, 1941, Fury fought the Nazis in Northern Africa, then was reunited with Captain Sawyer, who made Sgt. Fury the leader of the US Rangers’ First Attack Squad, soon nicknamed the “Howling Commandos” for their boisterous battle cry. Dugan served as Fury’s second-in-command and became his closest friend. The Howlers occasionally worked alongside Captain America (Steve Rogers) and Bucky (James Barnes), who became significant allies. During one mission, Fury’s left eye was damaged by a grenade and his lack of medical care eventually aggravated the wound. At one point, Professor Berthold Sternberg gave Fury the “Infinity Formula,” which retarded Fury’s aging process, although it required him to take regular injections to stay alive. Late in the war, Fury joined the OSS and with the war’s end joined their post-war CIA agency.
