There is no better time than the present for Gotham to capitalize on the popularity of Floyd Lawton, aka Deadshot. While Suicide Squad may have its flaws, one of its highlights is Will Smith's portrayal of Deadshot. Deadshot has already recently appeared in live-action television, being portrayed by
Michael Rowe in Arrow and The Flash (his Earth-2 version). While it may be too early for Deadshot to appear in Gotham, we could see a younger Floyd Lawton before he earns his reputation as the man who never misses.
Gotham would be smart to capitalize on the success of Suicide Squad by introducing Lawton. An interesting plot to explore would be his childhood, where he grew up in an abusive household, which is largely responsible for the career path he chooses. Lawton's journey to becoming Deadshot could parallel Wayne's inevitable transformation into Batman, and who knows, maybe we will eventually see an early version of Task Force X on Gotham, which would open up the possibility for other members of the Squad to appear.
