In such a fanfic, a really interesting plot twist could be that Harry fakes his death and as a result, Hogwarts itself undergoes some major changes. The school becomes more secretive and starts to develop new security measures thinking Harry is gone and they need to protect themselves better. Or perhaps Harry fakes his death and it turns out that there was a prophecy that predicted this event all along. This prophecy then leads to new revelations about his true purpose and the future of the wizarding world.
Well, it could be that Harry fakes his death and then assumes a completely new identity. He could be living among the very people he was fighting against, gathering information. And the twist is that he starts to have doubts about the side he was on all along, as he gets to know his enemies better from the inside.
In some versions of such fanfiction, Ash fakes his death as part of a master plan to stop an evil organization from achieving their goals. He stages his death in a way that makes the organization believe they are safe, but in reality, he is working behind the scenes, gathering evidence and allies. His friends initially mourn his loss, but as the story unfolds, they start to suspect that something is not right and eventually figure out his plan.
For Ron and Hermione, they would likely be devastated at first, thinking they had lost their best friend. But then they might start to suspect something when they notice small details that don't add up. Ginny would be heartbroken and might become more determined to fight against Voldemort in revenge. The Order of the Phoenix would be in chaos, with some members losing hope while others might start to investigate the circumstances of his 'death' more closely.
In the 'Harry Potter and the Twists of Fate Fanfic', a possible plot twist could be that the way magic works is suddenly changed. Maybe spells that were thought to be dark are actually the key to solving a great mystery. This would force the characters to re - evaluate their understanding of magic and their place in the wizarding world. It would also create new challenges and opportunities for the characters, leading to a whole new set of adventures and conflicts.
Maybe the Death Eaters save Harry, but then they try to use him as a bargaining chip. They think they can trade Harry's safety for something they want, like amnesty or a powerful magical artifact. However, things don't go as planned and they end up having to truly protect him.
One interesting plot twist could be a character who was thought to be dead actually being alive and having a secret plan all along. For example, in some fanfics, Itachi might not really be dead and his actions were all part of a greater scheme to protect the village in a different way.
It's possible that the plot twist involves the true nature of her death being different from what was initially thought. For instance, instead of being a simple execution by Jabba, her death could be part of a larger conspiracy. Maybe someone wanted her dead to start a war between different factions in the Star Wars universe, and her death was the trigger.
Harry is the main one as it's his faked death. Hermione, with her sharp mind, would be a mainstay in the story. Ron, with his loyalty and bravery, would be right there. Neville could also be a main character. He has grown a lot throughout the series and could be involved in the events surrounding Harry's faked death, perhaps even being one of the first to suspect something fishy. And then there's Ginny. As Harry's love interest, she would be deeply affected by his faked death and would be a central figure in the emotional turmoil of the story.
It's possible that a big plot twist in the fanfic is related to Harry's parents. Maybe they knew about his werewolf nature before he was born and had some sort of plan in place. Or perhaps Harry's werewolf condition was actually caused by something related to his parents' past or a secret they were hiding. This could completely change the way we view the events leading up to Harry's discovery of his werewolf side in the fanfic.
One possible plot could be that Naruto fakes his death to outwit a powerful enemy who has been targeting him directly. By doing so, he can secretly gather information and plan a counter - attack.
