In a world of brooding heroes and dark justice, one mercenary stands out—not for his skill, but for his relentless sarcasm and love for chaos. A self-proclaimed anti-hero, he finds himself working with the Titans, much to their frustration. While undeniably skilled in combat and nearly impossible to kill, his real talent lies in driving his teammates insane with endless jokes, fourth-wall breaks, and questionable decision-making. Whether it’s swapping Robin’s gadgets with toy versions, turning serious battles into slapstick comedy, or giving monologues mid-fight, he thrives on pushing everyone’s patience. But beneath the humor, there’s a sharp mind, a tragic past, and a surprising willingness to do what others can’t. While the Titans may roll their eyes at him, they also know that when things get truly dire, he’s the wildcard they need. Love him or hate him—he’s here to stay, and he’s having way too much fun.
