Prince Franz features as the prince in a horror anthology's Cinderella segment. He is the king's son, raised in isolation within castle walls, which stunts his grasp of the outside world and fuels his mental instability. Witnessing Helena's cruelty toward animals and stepsisters, Franz fixates on her, misinterpreting her malice as compelling strength. This obsession prompts him to host a ball solely to meet her. At the event, he forms an instant, intense attachment. Their relationship spirals into mutual destruction, with Franz actively enabling Helena's violence. He assists her stepfamily murder by drowning one stepsister in a well. The pair marry in a graveyard ceremony, marking their shared descent into darkness. Post-marriage, Franz confines Helena to a remote castle, echoing his own secluded upbringing. His mental state fractures further, erupting in violent outbursts whenever Helena attempts escape. His possessiveness escalates to physical attacks, including choking her during an argument. Franz meets his end when Helena stabs him during one such violent confrontation, terminating their toxic bond.
