Jasper Sitwell is an espionage agent working for S.H.I.E.L.D.
Sitwell gave Fury updates on Stark's status.
Jasper Sitwell is assigned to the surveilance of Bruce Banner. Even if the World Security Council orders to stop his mission, Nick Fury orders him to keep an eye on the scientist. When Phil Coulson discovers a mysterious alien device landed in New Mexico, Sitwell is re-assigned and leaves Banner's surveilance to Natasha Romanoff.
Agent Jasper Sitwell is sent to New Mexico after Agent Coulson finds Mjölnir in the desert. He's among the S.H.I.E.L.D. agents who confiscate Professor Selvig and Jane Foster 's research on wormholes.
Sitwell is head of the lab studying the hammer-like artifact found in the crater who also witnesses the intrusion of "Donald Blake" into the base. When the man is finally apprehended, Sitwell witnesses Coulson's interrogation of him.
When another wormhole is opened in the desert, Sitwell goes to the desert to check with Coulson and some other agents, only to witness the arrival of The Destroyer. He asks Coulson if the robot is something of Stark's, but Coulson responds that Stark never tells him anything. Immediately after, The Destroyer starts a massive attack against the agents, and Sitwell is among the survivors.
Agent Sitwell summons Agent Coulson to a meeting in a cafe to discuss a major problem: the World Security Council wants Emil Blonsky freed from custody and integrated in The Avengers Initiative. The two of them, knowing the truth about The Abomination, think of a plan to avoid Blonsky's liberation, and decide to send The Consultant to annoy General Ross, who has Blonsky in custody, to the point that he'll never release his prisoner.
Jasper Sitwell keeps serving under S.H.I.E.L.D., and is seen as a computer expert on S.H.I.E.L.D Helicarrier. He is the one who locates Loki in Stuttgart, and during Clint Barton's attack on the ship, Sitwell's abilities come in handy in regaining the control of the Helicarrier despite the heavy damages.
Agent Sitwell is partnered with Agent Blake to capture two bank robbers, who have at their disposal the only Chitauri gun, among the 47 retrieved on Earth, which is still functioning. Beating Blake on time, Sitwell manages to forsee the two's movements and to anticipate them, and reach them in a motel, with the order of collecting the weapon and killing the two.
Once at the motel, Sitwell takes the room next to Benny's and Claire's, disturbing them with music at high volume. Benny knock to his door to ask him to lower the volume, but Sitwell easily knocks him out and ties him. Benny, anyway, manages to warn Claire, who attacks Sitwell with the alien gun. During the following fight, the gun gets broken and shoots automatically, destroying most of the room. After that, Sitwell ties Benny and Claire and prepares to follow his orders, until he discovers that the gun was working because Benny, who is a scientist, repaired it.
Seeing a potential in the couple, Sitwell, instead of killing them, recruits Benny and Claire in S.H.I.E.L.D., much to Blake's disappointment.
