What are some interesting plot ideas for 'Harry Potter x Bellatrix fanfiction'?

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.

Well, it could be that Fem Harry Potter is actually a long - lost relative of Bellatrix's family. Bellatrix initially hates her because of her association with Dumbledore and the Order. But as the story progresses, they find out some dark family secrets that connect them. They then have to decide whether to keep fighting against each other or team up against a greater evil, like a new dark wizard who is more powerful than Voldemort and is threatening the wizarding world.

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 Harry discovers his true parentage and has to struggle with his identity. He might be torn between the side of good that he has known all his life and the dark legacy of Bellatrix. Another plot could involve him facing discrimination from both the wizarding world that hates Bellatrix and the Death Eaters who might see him as a tool or a threat. For example, he could try to use his knowledge of Bellatrix's magic, which might be more complex and dark - tinged, to fight against Voldemort in a different way than in the original story.

One idea could be a time - travel plot where Hermione somehow gets sent back in time and has to deal with a younger Bellatrix. Maybe she tries to change Bellatrix's path to the dark side. Another could be a magical duel between Hermione and Bellatrix where Harry is caught in the middle, forced to choose which side to help. Or a plot where Bellatrix, under some sort of spell, has to team up with Hermione and Harry to fight a greater evil.

One idea could be a story where Bellatrix and Narcissa are forced to work with Harry Potter due to some dark magic that binds them, and a lemon tree (represented by 'lemon' in a symbolic way perhaps) holds the key to breaking the spell.

One idea could be that Harry discovers a hidden side of Bellatrix where she has a group of followers who are all intrigued by Harry's power. They form an uneasy alliance at first, but as time goes on, they start to respect and care for each other in their own strange way.

She could travel back to the time when Voldemort was still in hiding as a young Tom Riddle. Bellatrix might try to influence him in a different way, perhaps making him even more ruthless. This would change the course of the wizarding world in a very different direction.

Well, perhaps there's a magical accident that causes Bellatrix and little Harry to be stuck in a time - loop or a magically sealed room together. At first, Bellatrix is enraged and wants to kill Harry immediately. But as time passes, she starts to notice Harry's courage and tenacity, which reminds her of the qualities she once admired in herself or others. Harry, in turn, tries to find a way to escape while also trying to figure out how to use Bellatrix's internal conflict to his advantage.

One idea could be that Bellatrix captures Harry with the intention of using him as a bargaining chip against Dumbledore. She might think that Dumbledore would sacrifice a great deal to save Harry. Another plot could involve Bellatrix trying to turn Harry to the dark side while he's in her captivity, perhaps by showing him 'truths' about the wizarding world that she believes in. Or maybe she captures Harry to extract information about the Order of the Phoenix from him.
