A possible plot is that Bellatrix's pregnancy is the result of a dark magic experiment gone wrong. The child could have some sort of special power or be a symbol of a new form of dark magic. This could lead to a race among the magical world to either protect or destroy the unborn child.
One idea could be exploring how Bellatrix's pregnancy affects her loyalty to Voldemort. Maybe she starts to question some of his more extreme actions as she thinks about the future for her unborn child.
A plot could focus on the relationship between Bellatrix and the father of the child. If it's a fellow Death Eater, how does their dynamic change? Do they become more protective of each other? Or perhaps the father is an unexpected character, like a wizard who was undercover among the Death Eaters. This would add a whole new layer of mystery and drama to the fanfiction.
A really interesting plot could be Bellatrix being given a chance at redemption. In this fanfiction, she could start to question Voldemort's motives after seeing the destruction he causes. She might then try to secretly help the Order of the Phoenix. Also, a plot about her teaching a young Death Eater the ways of the Dark Arts and having second thoughts about it mid - way through could be fascinating.
Some fanfics explore Bellatrix's family relationships more deeply. Like her relationship with Narcissa. There could be a plot where Bellatrix has to choose between loyalty to Voldemort and protecting her sister, which adds a lot of emotional depth.
It could be Voldemort himself. Given her extreme loyalty to him, it's not a far - fetched idea that there could be some sort of connection between them that led to her pregnancy.
The plot could involve the son trying to redeem his mother's name. He might go on a journey to find out more about her past, hoping to understand why she became so evil. Along the way, he meets various characters who knew his mother and has to deal with their mixed reactions towards him.
A possible plot is that Bellatrix is sent back to the time when the Goblin Rebellions were happening. She could side with the goblins to gain their trust and then double - cross them to steal their most precious treasures. Another idea is that she is sent back to the time when the Ministry of Magic was first established. Bellatrix might try to infiltrate it from the start and plant the seeds of dark magic within its very foundation. Also, she could be sent back to a time when a famous magical beast was first discovered, and she tries to capture and control it for her own evil purposes.
Well, a cool plot for a 'Harry Potter and Bellatrix Fanfic' might be that Bellatrix, in a moment of confusion during a battle, uses a spell that transports her and Harry to a different time period. There, they have to rely on each other to survive and in the process, Bellatrix starts to question her loyalty to Voldemort. Also, a plot where Bellatrix discovers that Harry has a hidden power that could be used to bring back someone she lost, and she bargains with him for it could be interesting.
One idea could be that the OC Lestrange is a distant relative who has been kept in the dark about the family's dark deeds. They could start at Hogwarts and gradually discover the truth, leading to an internal struggle between loyalty to family and doing what's right. For example, they might find out about the Horcruxes and have to decide whether to help Voldemort or oppose him.
Many fanfics explore the theme of redemption for Bellatrix. They imagine scenarios where she could have turned away from the dark side. Her complex character, with her madness and loyalty, also makes her a great subject for psychological exploration in fanfics.
Definitely. In the original plot, Bellatrix is a loyal follower of Voldemort and would never be expected to save Harry. But in a fanfic, the author can rewrite the rules. It might be that the fanfic delves deeper into Bellatrix's character, showing that she is not just a one - dimensional villain. There could be a moment of redemption for her, where she realizes that Harry represents something more important than her loyalty to Voldemort, and this realization drives her to save him.
