Clinton "Clint" Francis Barton, better known as Hawkeye, is a former special agent of S.H.I.E.L.D., where he worked under the supervision of Phil Coulson. Assigned by Nick Fury to watch over the Tesseract, he was brainwashed by Loki during the destruction of Project P.E.G.A.S.U.S. However, after the Attack on the Helicarrier, he was freed from Loki's mental control by Black Widow and joined the Avengers to fight against Loki's alien army in the Battle of New York, ending the Chitauri Invasion.
He then continued to work for S.H.I.E.L.D. until its collapse, after which he and the Avengers worked to bring down the remnants of the terrorist group HYDRA and the psychotic artificial intelligence, Ultron. After the Ultron Offensive, Barton chose to leave the Avengers to return to his wife and children. However, he was soon recruited by Captain America to aid him in his fight against the Sokovia Accords. Barton was briefly imprisoned at the Raft, but was secretly freed by Rogers.
