Fan Casting Harley Quinn in CW's Gotham Knights

The chaos agent. Former Dr. Harleen Quinzel, Arkham psychiatrist turned Joker's girlfriend, turned Suicide Squad survivor, now her own brand. She worked with Batman profiling criminals from Blackgate. When the Knights arrive instead of him, she processes his death in real time—a flicker of grief, then a unicorn balloon carrying evidence into the courtyard just to make them chase it. She escapes, reinvents herself as Doctor Q, and sells mind-control implants to a city desperate for answers. Her arc ends in white face paint, a black spade over her eyes, swinging an electrified sledgehammer. She is funny, dangerous, tragic, and never boring.
