History: In the late 1930’s the young Timothy Cadwallader "Dum Dum" Dugan worked as a strongman with a traveling circus. It was during this time that Dugan encountered the adventurer Dominic Fortune.

In early 1941 Dugan was traveling with the circus through Europe. In the Netherlands Dugan first met Nick Fury, the man who would become his closest friend, who was then a performer in a stunt flying act and parachute instructor. Fury was assisting the American military officer Samuel Sawyer on a secret mission to rescue a British agent before he was captured by the German forces that had invaded the Netherlands. Dugan agreed to help Fury and Sawyer, and together they succeeded in getting the scientist to England safely.

Inspired by this mission, Dugan decided to leave the circus and enlist in the British armed forces to help fight the forces of Nazi Germany. (At this point the United States had not yet entered World War II; Sawyer himself was working with the British at this time.)

After the Japanese attack on the American naval base at Pearl Harbor, Japan, in December 1941, the United States officially entered World War II. Dugan and Sawyer were both transferred to the United States Army's Rangers (soldiers fighting on commando missions). Sawyer's company of Rangers, including Dugan, battled German forces throughout Europe and in North Africa.

After Sawyer was forced to retire from combat duty due to injury, he and G-2 (army intelligence) together organized the First Strike Force, the special squad of rangers that came to be known as the Howling Commandos. Sawyer, who had become a colonel, arranged for both Fury, who had become a sergeant in the United States Army, and Dugan, who was now a corporal, to be assigned to this team. The Howling Commandos became legendary for their long string of remarkable victories over the Axis forces during the war. Dugan acted as Fury's second in command, and led the Howling Commandos on those occasions that Fury was unavailable.

For a short time during the war Dugan led his own ranger team, known as the Deadly Dozen, but he was soon transferred back to the Howling Commandos.

Like the rest of the Howling Commandos, Dugan reenlisted in the army when the United States entered the war in Korea in 1950. The army reunited the Howling Commandos, with Dugan again serving as Fury's second in command.

The Howlers reunited once again in the late 1960s to go on a special mission in Vietnam for the United States government. Dugan was no longer a member of the army at this time, and he, like the other civilian Howlers, went on the mission on a volunteer basis.

Presumably it was Nick Fury who brought Dugan and another former Howler, Gabriel Jones, into the international law enforcement agency, S.H.I.E.L.D., shortly after he became its public director. Dugan became one of Fury's top agents, assisting him in the battles against HYDRA, AIM, and the robot duplicate of the Yellow Claw.

When the gigantic mutant dinosaur known as Godzilla invaded the United States, it was Dugan who commanded the large special S.H.I.E.L.D. task force that was organized to hunt down and destroy the creature. This hunt, which lasted for months and included several battles with the monster, ended when Godzilla swam off into the Atlantic Ocean.

In recent years Dum Dum Dugan suffered a major heart attack, and as a result finally retired from combat activity for S.H.I.E.L.D., although he remained active within the organization.

Dugan was one of the handful of leading S.H.I.E.L.D. agents who were not killed and replaced by one of the artificially created human beings called the Deltites. Even after the Deltite infiltrators had Fury himself branded as a traitor to the organization, Dugan himself remained loyal to his old friend. Ultimately, the Deltite takeover was exposed and defeated by Fury and others. Fury subsequently persuaded the United Nations to disband S.H.I.E.L.D.

Dugan was among the few agents who accompanied Fury in his travels around the world to close down S.H.I.E.L.D. offices, discharge their remaining personnel, and destroy its more dangerous technology.

Dugan subsequently retired to spend the remainder of his life with his wife and grand children. However, after Mrs. Dugan was murdered by the Death's-Head Commandos (formerly part of HYDRA), Dugan joined the new, more efficient S.H.I.E.L.D. organization which Fury organized to replace its predecessor.
