The Most Famed Assassin In Dc Comics.
In Floyd's childhood, his mother and father hated each other. Floyd's mom hated her husband so much, that she hired Floyd and his older brother to kill him. While Floyd hated his father also, he didn't want innocent blood (including the blood that gave him life) on his hands. Floyd refused the task and planned on warning his father. However, his mom and his older brother locked him in a closet, until the task was done. Floyd found a way to escape confinement and he grabbed a rifle so that he kill his father, and gain acceptance again from his mother and brother. While on a tree outside, Floyd was locked-and-loaded to kill his father. However, things didn't go as planned. Instead the tree branch snapped and Floyd accidentally killed his brother that he loved dearly. Living with guilt to this very day, Floyd takes jobs so that he can eventually die himself. While he doesn't want to commit suicide, he does not care if he lives or dies. He will just be happy when his mind is at peace.
