There Is No Justice League
Deadshot is often a hired assassin, regularly boasting to “never miss.” He is capable of using a large variety of weapons, but is most frequently portrayed as using a pair of silenced, wrist-mounted guns. 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. Deadshot’s past is revealed in subsequent appearances.
Deadshot is portrayed as having a twisted code of ethics; as long as he’s been paid for an accepted hit-job, he will always carry it out – no exceptions. Batman was unable to get him to stop threatening a witness (who refused to testify as long as Deadshot was waiting to kill him if he did) by threatening Deadshot or his family (Deadshot rightly assumed that Batman was bluffing). However, Batman ultimately did get Deadshot to abort the hit – by “freezing” the bank accounts of the one who had hired Deadshot. Unable to get paid, Deadshot publicly canceled the assassination, letting the witness go free.
