Floyd Lawton, known as Deadshot, is a master marksman and professional assassin. Amanda Waller recruits him into Task Force X, coercing him with threats against his daughter to ensure compliance; protecting her remains his primary motivation. Transported to a fantasy world, he retains his signature firearm proficiency but faces ammunition scarcity, forcing resourceful adaptations like retrieving weapons from crashed equipment. His tactical precision and cold demeanor position him as a de facto field leader during missions under Rick Flag's oversight. Despite his expertise, social ineptitude defines key interactions; he remains oblivious to the profound resentment Ratcatcher harbors from past prison humiliations, misinterpreting their dynamic as friendship.

Flashbacks reveal deeper layers, including his military service and familial trauma, such as his daughter witnessing his violent actions. These contribute to a self-destructive inclination and a fierce protective instinct toward his child, forming his core psychological conflict. His initial reluctance to collaborate with the Squad evolves into mutual reliance, particularly evident in defensive actions toward teammates like Harley Quinn.

During the fantasy setting's climax, he acquires enchanted armor from Cecil, enhancing his capabilities with magical properties for the battle against the Undead King. His equipment includes retractable wrist-mounted firearms and a collapsible targeting helmet, maintaining his comic-accurate arsenal within the isekai narrative. His physical design presents him as a black man in this continuity.
