Fanfic about Harry allying with Voldemort: What could be the possible plotlines?

A possible plotline could be that Voldemort has a change of heart. Maybe he realizes that Harry has some power or knowledge that he needs, so he decides to carry Harry away to a secret location to extract that information from him.

One possible plotline could be that Voldemort realizes that Harry is the key to some greater power or knowledge that he wants to obtain. So, instead of killing Harry, he saves him from another dark wizard or a dangerous magical creature. Maybe he sees that Harry has a connection to an ancient magic that could help him rule the wizarding world in a more complete way.

One possible plotline could be that Harry discovers some sort of ancient magic or prophecy that binds him to Voldemort in a way that is not initially understood as a mate - like relationship. As they interact more, they start to see different sides of each other. Harry might try to change Voldemort, and Voldemort might find himself having unexpected feelings for Harry. Another plotline could involve a magical accident that fuses their magic in a way that creates this bond. Then they have to navigate their new relationship while dealing with the wizarding world's reactions.

One possible plotline could be Bellatrix's unwavering loyalty to Voldemort being tested. Maybe she discovers something about Voldemort's past that makes her question her blind devotion. For example, she could find out about some of his more cowardly actions that he has kept hidden from his Death Eaters. Another could be a scenario where Bellatrix tries to prove herself even more to Voldemort by taking on a dangerous mission that he initially doubts she can handle. This could lead to a deeper understanding between them, or it could backfire and cause a rift.

In some versions of this fanfic concept, Harry might surrender as part of a long - term strategy. He could be faking it to get closer to Voldemort and find a way to destroy him from the inside. He might endure a lot of hardships and mental torture while pretending to be a submissive prisoner, all the while looking for that one weak spot in Voldemort's defenses that he can exploit to end the Dark Lord once and for all.

One possible plotline could be Harry being held captive in one of Voldemort's dark lairs. Voldemort might use the Cruciatus Curse on him repeatedly to try and break his spirit or get information about the Order of the Phoenix. Harry could be isolated and tortured while his friends desperately search for him.

Perhaps Voldemort uses magic to brainwash Harry into thinking he is his pet. Harry then has to fight against this false identity while still being under Voldemort's control. The plot could involve Harry slowly regaining his true self and using his new - found knowledge of Voldemort's inner workings (from being so close to him) to defeat him in the end. It would be a journey of self - discovery and resistance.

One possible plotline could be Harry trying to find a way to break the forced marriage bond while secretly gathering allies to fight Voldemort.

Perhaps Voldemort discovers that there is a greater threat out there. In the fanfic, it could be that another dark force is emerging, and Voldemort sees Harry as an ally of sorts against this new threat. So, he decides to protect Harry in order to deal with this common enemy.

One possible plotline could be that Harry is tricked by Voldemort. Voldemort might use some powerful dark magic or false promises to make Harry believe that joining him is the right thing to do. For example, Voldemort could claim to have a way to end all the bloodshed in the wizarding world if Harry helps him.
