Fictional character history.
Barney Barton was born in Waverly, Iowa. He lost both his parents at a young age when his father, an abusive alcoholic, lost control of his car and collided with a tree. Barney and his younger brother Clint were sent to an orphanage. They stayed there for six years before running away to join the Carson Carnival of Travelling Wonder as roustabouts. The Swordsman, a member of the carnival with a popular swordplay act, selected Clint to be his new assistant. Feeling overlooked, Barney became jealous and bitter. Later, when Clint was severely injured at the hands of the Swordsman for discovering his embezzlement scheme, Barney condemned his brother for not remaining loyal to his mentor. Barney, having had enough of the carnival, decided to enlist in the army. He suggested that Clint should join him and make a fresh start. Clint declined his offer. Barney told his brother that the offer still stood, and he would wait for him if he changed his mind. The next morning, Barney stood at the bus depot, waiting and hoping his brother would change his mind. When Clint did not show up, a sorrowful Barney got on the bus and left his old life behind. As the bus was departing, Clint arrived, having changed his mind. However, he was too late.
Barney later became an FBI agent. His first assignment was to work undercover as a bodyguard for a criminal called Marko. Unbeknownst to him, Clint and his new mentor Trick Shot attempted to rob the criminal's mansion. Barney was shot with an arrow by Clint. When Clint learned what he had done, he refused to leave his brother's side and turned against Trick Shot. Trick Shot wounded Clint with an arrow and left.
His next undercover assignment was to pose as a racketeer. He was approached by Egghead, who offered Barney a place on his villainous space-station in exchange for funds. When Barney declined the offer, Egghead (actually a robot sent by the real Egghead) attacked him. With his bodyguards slain, Barney went to the Avengers (whose ranks included his brother Clint, then using the identity of Goliath) to help stop the supervillain. Barney and the Avengers battled Egghead and his robot soldiers inside the villain's space-station. During the battle, Barney sacrificed his life to destroy Egghead's deadly ray-projector. After the funeral, Clint received a letter from FBI agent Allan Scofield revealing Barney's double life. The letter also revealed that Barney was aware of Clint's double life.
Unbeknownst to Hawkeye and the Avengers, Barney's body was stolen by Egghead. Egghead discovered that Barney was still displaying faint vital signs and placed him in a healing chamber. Later, Egghead was inadvertently killed by Hawkeye in a battle with the Avengers, leaving Barney suspended and forgotten in the healing chamber. He was later discovered by Baron Zemo. Zemo, who held a personal grudge against Hawkeye, manipulated Barney to turn against his brother. Barney and his new "benefactor" enlisted Hawkeye's former mentor Trick Shot (whose cancer had returned) to train him to be as proficient with a bow and arrow as his brother. Once the training was completed, Trick Shot was badly beaten and his cancer was allowed to fester. Barney then delivered a dying Trick Shot to Avengers Tower as a message to Hawkeye. Later, while investigating his former mentor's death, Hawkeye was ambushed by his brother. Declaring himself as the new Trick Shot (but altering it to Trickshot), Barney subdued Hawkeye and delivered him to Baron Zemo. Zemo had the brothers duel to the death. Hawkeye (despite going blind from a previous injury with the third Ronin) managed to best Trickshot in battle. Before teleporting away, Zemo transferred Trickshot's criminal funds over to the "victor" Hawkeye, then taunted the hero for turning his brother against him. In custody, Trickshot agreed to a bone marrow transplant to save his brother's sight, but only so he could battle Hawkeye again in the future.
Norman Osborn later faked Trickshot's death in his hospital bed as Norman invited Trickshot to join his second incarnation of the Dark Avengers. Despite the new team's initial success, he was finally defeated in a fight with Mockingbird when he underestimated her capabilities, as Mockingbird had recently been enhanced by the Super Soldier Serum/Infinity Formula hybrid. After being arrested, Trickshot and the rest of the villains (save for Superia and Gorgon) are offered reduced sentences in exchange for signing on with the Thunderbolts program. Barney remains with the team until the Dark Avengers escape their handlers and disband.
Sometime after dissolution of the group, a homeless and disheveled Barney goes to live with Clint, with whom he apparently reconciled, at his new apartment.
As part of the "All-New All-Different Marvel", it is revealed that Barney had stolen Clint's wealth and moved to a private island to start a family with Simone, one of Clint's former neighbors. In "All-New Hawkeye," she is referred to by the name "Cheryl", despite being referred to as "Simone" throughout "Hawkeye" (vol. 4). Despite this, the two brothers remain on good terms. He even assisted Clint and Kate in rescuing the Project Communion kids from HYDRA and S.H.I.E.L.D.
