Deadshot is often a hired assassin, regularly boasting to "never miss." He is capable of using a large variety of weapons. He initially appears in Gotham City as a new crimefighter, but is revealed to be an enemy of Batman when he attempts to replace the Dark Knight. He is sent to jail when Batman and Commissioner Gordon publicly expose his plot to become the king of Gotham's underworld.

After serving his term, Deadshot begins hiring his services out as an assassin, changing his costume from the top coat and tails he previously wore to a red jumpsuit and distinctive metal face plate with a targeting device on the right side. He has been a major figure in the Suicide Squad in its latest two incarnations, where his skills as a marksman and his disregard for human life serve to greatly further the group's objectives.
