Fanfic about Harry raised by Sirius: What could be the main plot twists?

One possible plot twist could be that Sirius Black, being a wanted man, has to constantly move with Harry to avoid capture. This would make Harry's childhood very different from the one at the Dursleys. He'd grow up learning about the wizarding world on the run, perhaps meeting some unique characters in hiding places.

One possible plot twist could be that Harry, under Crowley's influence, starts to question the traditional concepts of good and evil in the wizarding world. He might be exposed to dark magic in a different light, not as something purely evil but as a tool with its own uses. This could lead to conflicts with his friends from Hogwarts who adhere to the more conventional views.

One possible plot twist could be that Amelia Bones, being a highly respected figure in the wizarding world, has a secret past that somehow affects Harry's journey. Maybe she was involved in some sort of pre - Voldemort plot that resurfaces when she takes in Harry. This could lead to Harry having to deal with new enemies and allies that are related to Amelia's past.

One possible plot twist could be that Sirius Black has a noble reason for 'kidnapping' Harry. Maybe he discovers a plot against Harry within Hogwarts that the school's authorities are ignoring. So, he takes Harry away to protect him. For example, he might find out that a certain teacher is under the influence of Voldemort and plans to harm Harry. Another twist could be that Sirius Black is being controlled by a dark magic spell and doesn't really mean to harm Harry. It could be a setup by Voldemort's followers to make Sirius look bad. Also, it could turn out that the 'kidnapping' is part of a secret training plan for Harry. Sirius wants to train Harry in some special magic skills away from the prying eyes of Hogwarts.

The plot could take a turn where Pan Son is initially thought to be a normal Muggle, but as he grows up with Harry, it's revealed that he has a dormant wizarding bloodline. This discovery could come at a crucial time, like when Harry is facing a great threat. Pan Son's newfound magic could be the key to turning the tide. They would then have to train Pan Son quickly and figure out how to integrate his magic into their fight against the dark side.

One possible plot twist could be that Harry, under Bellatrix's influence, becomes a much darker and more ruthless wizard. Bellatrix might train him in the Dark Arts, and he could end up being a sort of anti - hero. He might have a completely different view of the wizarding world and be at odds with his former friends from Hogwarts.

One possible plot twist could be that Ariel, while being raised by Ursula, discovers a hidden power within herself that Ursula was trying to keep dormant. Maybe it's a special kind of magic that can break Ursula's control over the sea creatures. This would lead to a power struggle between them as Ursula tries to regain control and Ariel fights for her new - found freedom and the rights of the underwater world.

A really interesting plot twist could be that Zabuza has a hidden past or connection to Naruto's family. For instance, perhaps he knew Naruto's father in a different context than what was previously known. This could change Naruto's whole perspective on his family and his place in the ninja world. Or, Zabuza could have been given a secret mission long ago related to Naruto that he never fully completed, and now raising Naruto becomes a way to fulfill that mission. This would add a whole new layer of mystery and depth to the fanfic.

Perhaps a plot twist could involve Dionysus having a secret reason for raising Percy. It might turn out that Percy is part of some grand prophecy that only Dionysus knows about, and he's been grooming Percy for a specific task that will change the fate of the gods and demigods alike. This could lead to Percy having to make some really tough choices between his loyalty to Dionysus and his friends at Camp Half - Blood.

One possible plot twist could be that Naruto develops unique jutsu influenced by Yugito's Nibi powers. Since Yugito is a jinchuriki, she might teach Naruto some special techniques related to chakra control and dealing with tailed beasts. For example, Naruto could learn a new form of Rasengan that incorporates some of the Nibi's chakra nature.
