Fictional character biography
Mitch Carson was a high-ranked S.H.I.E.L.D. security agent. He had killed his father when he was fifteen years old and many others after that. He had, however, never been caught for any of those crimes and managed to find employment with S.H.I.E.L.D.

Carson was part of the S.H.I.E.L.D. team that took the Iron Maniac into custody. The alternate Stark was held alongside the Life Model Decoy (LMD) of Diamondback. His body somehow adapted to the sedatives used, and he attacked the agents watching him, then activated the LMD coercing it to help.

Carson was supposed to become the wearer of the newest Ant-Man suit made for S.H.I.E.L.D. by Hank Pym. The suit was thought to be stolen, but it actually disappeared by accident when Agent Chris McCarthy tried it on. Chris was later killed during a Hydra attack on the Helicarrier, and it was then that Eric O'Grady took the suit for himself.

Carson was determined to find the suit and bring in whoever stole it. During his mission to capture the new Ant-Man, he was heavily burned in the face during a fight with him. After that, it did not take long for Carson to find out that the new Ant-Man was actually O'Grady.

Eventually, Carson used an older Ant-Man suit and managed to confront and capture O'Grady. Instead of bringing him to justice, however, Carson planned to torture him. Carson confessed his crimes but before he could kill O'Grady, Iron Man arrived and intervened. Seeing Carson in the Ant-Man suit while torturing O'Grady, Stark fought and defeated him. O'Grady lied to Stark and told him that Carson killed McCarthy and tried to steal the suit. O'Grady claimed to be on the run from Carson and trying to prevent him from getting the suit. Carson was arrested for attempted murder and stealing the Ant-Man suit.

Powers and abilities
Carson has S.H.I.E.L.D. training, specifically in firearms/explosives, espionage, intelligence gathering, and hand-to-hand combat.

He gained access to an old Ant-Man suit and used it to shrink and take out Eric O'Grady wearing more advanced G.I.Ant-Man suit.
