What are some possible plot twists in a 'Harry Potter' fanfic about an assassin betrayed by Moody?

I'm not sure of a specific one off the top of my head. But you could try searching on fanfic websites like FanFiction.net or Archive of Our Own. Use the keywords 'Harry Potter', 'assassin', 'betrayed' and 'Moody' in the search bar to narrow down the results.

Well, one possible motive could be that the assassin is working for Voldemort. Moody was a powerful Auror and a threat to Voldemort's plans. By eliminating him, it would clear the way for the Dark Lord's operations. Another motive might be personal revenge. Maybe Moody had put someone close to the assassin in Azkaban in the past, and this was a way to get back at him.

In these fanfictions, a really cool plot twist could be that Moody, because of his experience with the dark arts, has knowledge of a secret power within Harry that even Voldemort doesn't know about. He nurtures this power in Harry, which makes Harry a completely different kind of threat to the dark forces. Maybe it's a power related to the ancient magic of the founders of Hogwarts that was passed down in a way no one expected.

Maybe it's a character who has a hidden identity. It could be someone who was thought to be dead but actually survived and is now seeking revenge. This person could have a grudge against Moody for something that happened in the past. Or it could be a new character created specifically for the fanfic, a dark wizard from a far - off land who has been hired to kill Moody.

Well, a really interesting plot twist could be that when Voldemort controls Harry, Harry's personality starts to merge with Voldemort's in unexpected ways. For example, Harry might start to understand Voldemort's motives and see some truth in his views about the wizarding world, which creates an internal conflict for Harry. Another plot twist could be that the magic used to control Harry has a side - effect that it also starts to affect Voldemort's own magic in unforeseen ways. Maybe it makes Voldemort more vulnerable or changes his appearance. And there's always the chance that the control is not just a simple spell but a complex magical ritual that was set in motion long ago, and Harry has to figure out how to reverse the entire ritual to break free.

Maybe he would be trained to be a super - powerful dark wizard. However, his natural good - heartedness, which he got from his parents, starts to shine through. This could lead to a conflict within the Death Eater community. He might be seen as a threat to their ideology and have to fight for his life against those who raised him.

In this fanfic, a really cool plot point might be how Moody's artificial eye plays a part in Harry's upbringing. Moody could use it to teach Harry about seeing through disguises and hidden threats. Also, Moody's no - nonsense attitude might make Harry a more disciplined wizard. He might not tolerate any sloppiness in Harry's magic, which would lead to Harry being a more precise and powerful wizard in the long run.

One possible plot twist could be that the troll is actually under the control of a dark wizard. So when Harry saves Hermione, they realize that there is a much bigger threat at hand. Another twist could be that the troll turns out to be a transformed Hogwarts student, and they have to find a way to reverse the spell instead of just fighting it.

In a 'Harry Potter betrayed fanfic', perhaps Hermione turns against Harry. It could be because she disagrees with Harry's more dangerous and reckless plans to fight Voldemort. She might think he's endangering too many lives without proper thought, and this leads to a rift and a sense of betrayal.

In a 'Harry Potter is an assassin' fanfic, the plot could start with Harry being trained by an unknown and powerful wizard who has his own motives for creating an assassin out of Harry. This trainer could be someone from a far - off land or an ancient order. Harry then starts taking on targets within the wizarding world that are supposedly 'evil' but as he delves deeper, he realizes that things are not as black and white as he was told. His friends start to notice his strange behavior and he has to either come clean or keep lying to them. As the story progresses, Harry might have to make some tough choices between his loyalty to his friends and his new - found assassin duties, all while uncovering secrets about the wizarding world that were previously hidden.
