Dum Dum Dugan

"Hell, I'll always fight. But you got to do one thing for me." "What's that?" "Open a tab."

- Dum Dum Dugan and Steve Rogers

Timothy "Dum Dum" Dugan is a member of an elite special unit of Allied soldiers formed in World War II known as the Howling Commandos.

World War II
Timothy Aloysius "Dum Dum" Dugan is an Allied soldier who was captured by HYDRA. When Captain America single-handedly assaulted the facility in which he was prisoner, Dum Dum along with his companions broke free and wreaked havoc on the HYDRA agents, returning to the US military base immediately after.

Shortly after their break-out, Dugan and his comrades were invited to join a special elite commando unit led by Rogers himself. Dugan happily joined, saying he's always ready for battle, as long as someone pays for his drinks. Along with the other Howlers, Dugan takes part in every assault against HYDRA, until, during the one at Johann Schmidt's fortress, Cap goes missing in action.

Post-war activities
One year after the war, Dugan sat by a swimming pool with Howard Stark. They discussed bikinis – Dum Dum asked Howard if he invented them and he said no, it was the French.

Cold War
At some point after World War II, Dugan joined the Strategic Homeland Intervention, Enforcement and Logistics Division. During the Cold War, he and his partner Nick Fury were sent to Russia. After Fury ended his mission, he called Dugan, who asked how Fury's ally Escobar was. Fury told him that Escobar flipped. With Escobar gone, Dugan stated that it was time to celebrate, and Fury told him to not start without him, as he was bringing cigars with him.

Personality
Dum Dum Dugan is a belligerent but witty person, a gentle giant who hates injustice and is extremely loyal to his comrades. As a member of the Howling Commandos, he's recognised as one of the most skilled soldiers in US Army. He's highly trained, and he possesses a great amount of strength. After they broke into a HYDRA facility, he took some of their enhanced guns which he used in battle.

Trivia

 * Alongside Gabe Jones, Dum Dum Dugan is the only original Howler that appears in the movie.
 * In the comics, Dugan goes on to be a top tier S.H.I.E.L.D. agent and the right hand man of Nick Fury.
 * In a deleted scene from Captain America: The First Avenger, when Dugan and his friends are under attack from the German troops, Dugan says: "I hate these guys.". This could be a reference to Indiana Jones' opinion on the Nazis, who also hates them.
