As an agent of S.H.I.E.L.D., Coulson attempted to set up meetings with Tony Stark regarding his abduction and subsequent "rescue" in Afghanistan, but Stark refused, instead Coulson received information from Pepper Potts about Obadiah Stane's involvement in Tony's kidnapping and attempted homicide. Coulson and four other agents tried to arrest Stane, but their efforts were thwarted by the Iron Monger Armor. Coulson later derived a cover story for Stark of his secret identity, one which Stark refused to use.

Watching over Stark
Nick Fury put Agent Coulson in charge of guarding Stark, making sure he didn't leave his house. Later, Coulson went down to Stark's workshop and found a prototype of Captain America's shield in Howard Stark's casket, Stark took the shield and used it to balance the machine he was building. Coulson was assigned to a different mission so bid farewell to Stark.

Gas station robbery
While going to New Mexico, Coulson stops in a service station to buy some snacks and fill his car with gas. While he's in the shop, two robbers threaten the clerk with shotguns. Coulson intervenes, passing them his car keys, but showing them his gun they panic, as he slides the gun to them, he quickly knocks both of them unconscious using his S.H.I.E.L.D. training. He goes to the counter and buys two snacks, pays, tells the clerk to keep the change and then leaves.

Finding Mjolnir
Upon arriving in the deserts of New Mexico, Agent Coulson along with a unit of S.H.I.E.L.D. agents set up a perimeter and a base of operations around the crater site containing Thor's hammer, Mjolnir.

When Thor attempted to reclaim Mjolnir by infiltrating the Shield base and manage to single-highhandedly take out a dozen of Shield agents with various fighting styles. Coulson observe from a distance but not before asking Clint Barton to prepare to take action if necessary. After Thor failed to remove Mjolnir, Coulson interrogated Thor about his identity and his training believing him to be a warrior of some type despite Thor refusing to answer his questions. Thor's interrogation was interrupted when Erik Selvig appears and informs Coulson that Thor is actually Donald Blake a member of his scientific staff. An agent confirms it by running a background check in the computer database and turns up a falsified document created by Jane of Thor assuming the identity of Dr. Donald Blake. Coulson goes along with the charade but secretly assigned agents to follow them believing they know more than their letting on.

Attacked by the Destroyer
When an agent discovers the coordinates of another potential crater site that appears to having an exact signature match to Mjolnir. Agent Coulson and a unit of SHIELD agents go to investigate and find The Destroyer armor, One agent asked Coulson if the armor belongs to Tony Stark. Coulson replied that Stark doesn't tell him anything at first he assumes it is Stark when he address the armor until it attack them.

Coulson manages to survive the attack from The Destroyer and manages to see Thor regain his powers. Coulson confronts Thor and Thor offers his services in protecting Earth under the sole condition that Coulson return all of Jane's research and material back to her. Coulson agrees to Thor's terms and request that they be debrief just before Thor flies upwards with Jane in his arms.

Stopping Abomination joining the Avengers
Jasper Sitwell meets with Coulson in a cafe. Coulson has been informed that the Government wants to free Emil Blonsky, considering him a war hero, who destroyed half a city just because he was attacked by The Hulk. The two are tasked with preventing Blonsky's release, and decide to send a consultant to talk to General Ross and convince him not to free the Abomination, someone so irritating and annoying that Ross would be forced to give up his plans. Unwillingly, Coulson accepts to send Tony Stark, The Avengers's consultant.

Loki's attack
Agent Phil Coulson is veteran S.H.I.E.L.D. operative who is always seen in a suit and necktie despite the fact that he is the agent most often in the trenches, carrying out Director Nick Fury's directives. The go-to agent for Fury's sometimes secretive missons, Agent Coulson has proven himself to be bo more than capable of handling the world's most powerful Super Heroes-though he is a human being with no super powers os super abilities. As S.H.I.L.D.'s "everyman" Coulson is dependable and loyal and unabashedly a fan of Captain America. When a threat to the world requires the formation of a team of Super Heroes to defeat it, Coulson takes on the task of assembling Nick Fury's Avengers as just another day at the office.

Convincing Tony Stark

Coulson reaches Loki's prison, only to find the villain out of his cage, and Thor trapped in his place.

Laying on the floor, Coulson assists powerless to Thor's expulsion from the Helicarrier, but manages to land a blow on Loki with his gun.

Character traits

 * In the films of the Marvel Cinematic Universe, Agent Coulson is generally depicted as a supporting character of the protagonists and used to represent S.H.I.E.L.D.'s presence in the plots of the films, to the point that Clark Gregg has described Coulson as "the S.H.I.E.L.D. agent". However, in the "Marvel One-Shots", Coulson is given "a chance to stand in his own spotlight for once", when the character is put in a position where there is an imminent threat and no superheroes around. The decision to give more focus to Coulson was "a natural" for "Marvel One-Shot" co-producer Brad Winderbaum.
 * Gregg has stated, "I think of Agent Coulson, after all these years, as a guy with a full life. I think every day he's somewhere doing something for S.H.I.E.L.D., and yet I don't always know what that is... There's always a different twist. In this one he gets to show more of his wisecracking wit, and in this one he's a little bit more of a badass."
 * Despite Coulson being called "the most recognizable face in the Marvel Comics movie universe", he is depicted as an "everyman" in a universe full of superheroes – "the glue that binds" the characters together. In Thor, Coulson complains that Tony Stark "never tells [him] anything." In an interview with WNBC, Gregg explained his portrayal of the character as 'just a guy grumbling about his job "He's the guy who's tasked - a very disciplined guy in my opinion who possesses secrets that would turn your hair white - but at the same time he's tasked with handling these kind of diva superheroes, you know? "Oh, really, Asgard? Dude, just get in the car."
