Dum Dum Dugan  Timothy Aloysius Cadwallader "Dum Dum" Dugan is a fictional character appearing in American comic books published by Marvel Comics. He is an officer of S.H.I.E.L.D. and is one of the most experienced members of Nick Fury's team, known for his marksmanship with rifles and impressive physique. He is recognized for his trademark bowler hat. Neal McDonough appeared as the character in the 2011 Marvel Cinematic Universe film "", the 2013 Marvel Studios short film "Agent Carter" (post-credits) and also in 2015 in the fifth episode of Marvel's "Agent Carter". Dum Dum Dugan first appeared in "Sgt. Fury and his Howling Commandos #1" (May 1963), and was created by Stan Lee and Jack Kirby. Dum Dum Dugan received an entry in the "Official Handbook of the Marvel Universe Update '89" #2. Dum Dum Dugan was originally portrayed as a British citizen in "Sgt Fury" #1, but later retconned to be born in Boston, Massachusetts. During World War II, while working as a circus strongman, Dugan helps Nick Fury and Sam "Happy" Sawyer escape the Nazis during a mission, recounted in issue #34. Dugan joins the British Army, and when Sawyer is charged with creating Fury's "First Attack Squad", formally listed as "Able Company" and nicknamed the "Howling Commandos", Sawyer invites Dugan to transfer into the US Army and become Fury's second-in-command. Dugan's exceptional strength saves the day in several of his adventures in the "Sgt. Fury" comic books. Dugan is an enlisted man with the rank of corporal, and wears the chevrons of his rank on the front top of his trademark bowler hat throughout World War II. Dugan leaves the U.S. Army before the Korean War, but rejoins during the war as Second Lieutenant under the promoted First Lieutenant Fury, once again as his second-in-command of the reformed Howling Commandos. Fury had already received a battlefield promotion to Second Lt. earlier. Dugan remains with Fury when Fury continues his military career into the Vietnam War, as shown in "Sgt. Fury and his Howling Commandos" Annual #3 and 4, and later into espionage work. Dugan's exact rank is not stated, but he is addressed as "Captain" at one point.
