Clint Barton

"'My name is Barton, codename Hawkeye. I use a bow and arrow, and haven’t missed a target in going on three years now. And I’m an Avenger.' (Live To Rise)"

Clint Barton is a prominent SHIELD operative and founding member of both the Avengers and the Order of the Phoenix. He is the greatest human marksman in the universe, most often using a bow and arrow. He is also a loving husband and father of two.

History
At a young age, Clint became involved with the Quentin Carnival. He took on the persona "Hawkeye", and perpetually pushed himself to achieve more and more advanced feats of archery and showmanship, in rivalry with another act, "Trickshot".

Not long after the debut of Superman, Clint witnessed Trickshot sneaking out in the night. He followed his rival, suspecting a secret girlfriend he could mock him about later. But instead he saw Trickshot using his talents to rob several nearby stores. A few days later, Clint heard an unrelated robbery, and fired three arrows that stopped it.

Over the following months, crime rates in neighborhoods visited by the Quentin Carnival dropped dramatically. He finally came at odds against Trickshot when he learned his rival had taken an assassination contract. He stopped Trickshot, and was contacted personally by Nick Fury shortly after. He left the carnival and joined SHIELD.

Some years later, he was assigned to eliminate a Russian assassin called the Black Widow. When he met her, he instead recruited her into SHIELD. The two quickly became lifelong friends and partners. Later, he met and became romantically involved with a woman named Laura. He requested that Fury expunge Laura from his file to prevent his enemies from finding her, which Fury obliged to. He and Laura would later get married in secret, and have two children.

In 2011, he was sent to New Mexico to guard an 0-8-4 that had crashed in the desert; a hammer. There, he met a woman named Xavier Bronze, who claimed to herald from another universe, and proved uncannily knowledgeable on several subjects, including limited knowledge of his children. The woman became a SHIELD consultant, and later told Clint about Hydra's infiltration of SHIELD. She, Clint, and Phil Coulson founded the Order of the Phoenix. Clint told Natasha Romanoff and recruited her into the Order soon after.

Later that year, Clint became a founding member of the Avengers. Alongside his new teammates, he assaulted several Ten Rings facilities worldwide, and captured Aldrich Killian.
