Crossbones possesses no superhuman powers, however he is proficient in various weapons, including pistols, his signature crossbow-pistol, and blades which project from a switch-blade mechanism mounted on his wrists.
The man now known as Crossbones grew up as a petty criminal and leader of his own band of ruffians. His brutality and viciousness led him to follow a life of crime.
In his first known activity as a mercenary, calling himself Frag, was to storm the castle of the criminal geneticist Arnim Zola, only to be repulsed by Zola's servant, Doughboy. Impressed by Frag's ferocity, the Red Skull, Nazi criminal and associate of Zola, spared his life and imprisoned him. Even under torture, Frag refused to talk to the Skull, and even challenged him to a man-to-man fight. The Red Skull agreed, in part to test his new body, which was cloned from his hated enemy, the hero Captain America. Even though the Red Skull defeated Frag, he offered him a position of bodyguard, calling him Crossbones.
