In this fanfic, the most thrilling part could be when Bella and Peter are in a dangerous situation in the past. For example, they might be caught in the middle of a historical battle or face some sort of persecution. They would have to rely on each other to survive, and their relationship would be tested. This would create a lot of suspense and keep the readers on the edge of their seats.
I think the most exciting part would be when Bella and Peter start to influence the past in some way. Maybe they accidentally change a small event, and then they have to figure out how to fix it or deal with the consequences. It adds a lot of drama and tension to the story.
Maybe Bella will have some amazing adventures with Peter in the past. She could witness historical events together with him, or they might fall in love in that different time period.
She might meet her younger self. It would be an odd yet fascinating encounter, as she could see how she used to be and compare it to who she is now.
I think the most exciting part is when Peter Pan rescues Wendy from Captain Hook's clutches. It's full of action and tension. Peter shows his bravery and flying skills, and there's a real sense of danger as Hook tries to stop him. Also, the whole atmosphere in that scene on the pirate ship is really thrilling.
Captain America and Peter would also have great interactions. Steve Rogers could teach Peter about the importance of responsibility and leadership. And Peter, with his youthful enthusiasm, could remind Steve of the good in the world and the future.
The fight between Peter Pan and Captain Hook is the most exciting part.
The sorting ceremony is often exciting. Imagining which Hogwarts house each BTS member will be sorted into is really cool. Like, will RM be in Ravenclaw for his intelligence? Another exciting part is when they face magical challenges together, just like how they face difficulties as a group in real life.
The main character is Naruto. In the past, he will surely encounter his parents. Minato and Kushina would be important characters in this fanfic. Also, Jiraiya, his mentor, would be a key figure. Since Naruto is going to the past, he might seek Jiraiya's guidance even more. And characters like Orochimaru would also be part of the story as Naruto may try to stop Orochimaru's evil plans earlier.
He will surely meet the Black Panther. It's Wakanda after all.
She might meet Aro, one of the leaders of the Volturi.
Maybe in the fanfic, Bella goes to the past and meets Carlisle when he is still struggling with his new - found vampire nature. She could offer him a different perspective on being a vampire, perhaps a more human - centered view. This could lead to a deep connection between them and change the way Carlisle interacts with other vampires in the future. It could also lead to a different relationship between Bella and the Cullen family when she returns to her own time.
