Disillusioned at the law's inability to protect society from the lawless, Houston Police Officer Bart Gallows resigned from the force and became America's self-appointed top law-enforcement official: Americop. Believing himself the future of law enforcement, Americop traversed the nation, monitoring police scanners and meting out justice to those he deemed perpetrators, acting as judge, jury, and, more often than not, executioner. Occasionally confiscating money from drug busts, he donated half to drug rehabilitation programs and kept the remainder to maintain his arsenal. While tracking a child abduction ring across the United States, Americop clashed with Captain America (Steve Rogers), who was appalled by his brutality. Americop's investigation led him to the New Orleans mansion of indestructible munitions magnate Damon Dran. Although initially subdued by a gas grenade attack and imprisoned alongside Captain America, the determined Americop broke free and killed several of Dran's mercenaries. He shot down Dran's retreating helicopter before escaping. He mistakenly believed that he had killed Damon.
Recently Norman Osborn targeted Americop as the Thunderbolts next target. Osborn however only chose Bullseye and Penance to capture him, hoping that would toughen Penance up. During the fight that followed Penance released an energy surge that paralyzed Americop. The two Thunderbolts then carted Americop off to the T-Wagon to take him back to Thunderbolt Mountain.
