A great plotline in such fanfictions can be Peter's relationship with his enemies after being revealed. Some enemies might respect him more for being honest, while others might see it as an opportunity to take him down. Another aspect could be his relationship with the police. They might either work more closely with him or try to regulate his activities. Additionally, a plotline could be Peter having to train new superheroes in secret to help him fight crime now that his identity is out.
One interesting plotline could be Peter's friends and family adjusting to his secret identity. For example, his aunt May might have a mix of pride and worry. Another could be how the public reacts. Some might see him as a hero, while others might fear his powers. And a third plotline could be Peter dealing with villains who now know his true identity and target his loved ones.
Well, in some fanfictions, when Peter is revealed, there's a plotline where he has to deal with the media frenzy. Reporters are constantly hounding him, asking invasive questions. Also, there could be a plotline where he tries to form a new superhero team with other revealed heroes to protect themselves and the city better. Or perhaps a plotline where Peter struggles with his normal life as a student because his identity revelation has made it difficult for him to blend in at school.
Perhaps Peter is alone in a forest, away from the city. He's there to find some peace and quiet, to get away from the chaos of New York. While he's alone, he reflects on his powers and how they've both blessed and cursed him. He might even start to train in new ways, using the seclusion of the forest to his advantage.
In many fanfictions where Peter's identity is revealed, it often leads to a whole new set of challenges for him. His friends and family might be in danger. For example, in some stories, villains target Aunt May to get to Peter. This forces Peter to be more protective and also changes his dynamic with his friends. They might either support him wholeheartedly or be scared of the danger he brings.
One interesting plotline could be that when Marinette is revealed, her friends are initially shocked but then quickly come to support her. They realize that all the times she seemed a bit flustered or had strange disappearances were because of her secret identity. For example, Alya might feel a bit guilty for not realizing it sooner but then uses her blog to help Marinette manage the public's reaction.
One interesting plot twist could be that Peter's friends, instead of being shocked, already knew his identity all along and were just waiting for him to tell them. They had noticed small things like his disappearances during Spider - Man activities and put the pieces together.
Often, Peter has to face new enemies. Since his identity is out, villains who were previously afraid of him being anonymous now come out of the woodwork. They see it as an opportunity to take him down when he's vulnerable.
One interesting plotline could be the discovery of the Miraculous by the entire world leading to a new global order. Governments might try to regulate the use of the Miraculous, causing conflict between the heroes and those in power.
One common theme is the struggle for normalcy. Peter still wants to have a normal life but his revealed identity makes it hard. Another theme is trust. He has to figure out who he can trust now that his identity is known. And finally, there's the theme of responsibility. He has more responsibility not only to protect the city but also to protect those close to him who might be in danger because of his revealed identity.
In some fanfictions, there could be a story where Harry discovers Peter's secret identity in a unique way. Maybe he stumbles upon Peter changing into his Spiderman suit by accident. Then, their friendship takes a new turn as Harry has to decide whether to support Peter or be angry about the secrecy.
One interesting scenario could be Peter and Gwen going on a double - date with their superhero friends. They get to show a different side of their lives outside of the web - slinging and science stuff.
One possible plotline could be the two Peters from different universes teaming up to fight a new threat that the Avengers can't handle alone. Maybe they use their combined spider - powers in unique ways.
