2016's Deadshot. The rivalry between the two is only briefly touched upon in the film, but the sheer hatred Deadshot feels for the Dark Knight - and the reasons why - is left out entirely.
In the film, Floyd Lawton meets Batman in only one scene. Batman attempts to apprehend Lawton while he walks through an alley with his daughter. Deadshot's daughter is a recent addition to the mythos as, in Deadshot's debut issue, no family is mentioned. Batman #59, by Bob Kane and Bill Finger, depicts Deadshot as a suave debonaire gentleman in a three-piece suit, with a top hat, two guns, and a plan to oust Batman as Gotham's protector... before becoming Gotham's number-one crime lord.
Deadshot partners up with Batman, often capturing criminals before the Caped Crusader. His aim is so precise that he never kills an enemy - but he still plans to shoot Batman in a terrible "accident." Deadshot's plan fails miserably - he keeps missing Batman (because Batman toyed with his gunsights the night before), and Lawton is arrested. A whopping twenty-seven years later, Detective Comics #474 depicts Deadshot's triumphant return and his desire for revenge. Written by Steve Englehart with art by Marshall Rogers and inks by Terry Austin, Deadshot escapes from prison after years of obsession with Batman. He no longer wants to play the long game - now he simply wants to shoot to kill.
"I practiced sighting a hundred times a day!" cries Deadshot as he fights Batman in his newly redesigned and more functional costume (complete with his now-signature red eye and wrist guns). "With my comb, my finger-!" The confident but flamboyant Deadshot from the 50s is gone, and in his place is someone altogether more deadly and dangerous. Batman's utter humiliation of Floyd Lawton in Batman #59 resulted in a man who rose from a simple "good marksman" to one of the deadliest humans on Earth with a firearm - any firearm. In a sense, Batman's actions created the modern-day Deadshot in the same way that Joe Chill created Batman.
In Batman #59, Deadshot was a simple villain with a simple gimmick. His costume didn't stand out in the slightest (apart from his hat), and he was disposed of after only one issue. But Deadshot's return was in keeping with the tradition of the late 70s: taking goofy Batman Silver Age concepts and characters and putting them in a darker, more "realistic" context. In that respect, the Suicide Squad film could only tell the story of Deadshot's obsession with Batman if the story spanned twenty-seven years.
