Fan Casting "The Maniac" in Batman: Birds of Prey

After Roman Sionis took his own life in the final battle by shooting himself through the chest with one of his deagles, then falling out the window of his office in Clayde Manor, Deadshot and Harley Quinn manage to escape, with Floyd continuing to live in the shadows as a go-to mercenary, while Harley is eventually found by the G.C.P.D and taken back to Arkham Asylum. However, while she is in her cell, sobbing about the fact she failed to avenge Arthur Fleck's death, a gravely voice in the cell next to her comforts her. She asks who this is out of curiosity, and the voice replies: "The name's Jack... But you can call me Joker, m'lady."
