Perhaps Spider - Man could create his own team of young superheroes who are inspired by the ideals of both sides. His team could then try to show the older heroes that there is a middle ground. They could start by doing small acts of heroism that don't take sides but help the general public. This would attract the attention of both Team Cap and Team Iron Man and make them question their own stances in the Civil War.
A plot idea could be that Spider - Man discovers a hidden agenda of one of the sides during the civil war. He then has to decide whether to expose it or keep it to himself, as it could have far - reaching consequences for the superhero community.
One idea could be that Peter Parker decides to unmask himself as a political statement during the Civil War. He might feel that the secrecy in the superhero community is causing more harm than good and by unmasking, he hopes to start a new era of transparency among heroes.
One interesting plotline could be Spider - Man trying to regain the trust of the public. After the events of Civil War, he might be seen as a bit of a wildcard. So, he could be doing small - scale heroics to show that he's still on the side of the good. For example, helping out at local charities or stopping petty crimes in a very public way to win back the hearts of the people.
Well, you could also have a plot where the secrets that were buried during the civil war start to surface in the aftermath. Maybe there were hidden alliances or betrayals that now come to light and create new tensions. It could involve characters having to deal with the truth about their past actions or the actions of their loved ones.
Perhaps there's a fanfiction where Spider Man and Spider Gwen accidentally swap powers. They have to learn how to use each other's abilities to fight crime. This would lead to some really funny and also challenging situations as they get used to different ways of web - slinging and sensing danger.
One idea could be exploring the different Spider - People's home universes in more detail. For example, showing what Miles Morales' daily life in his universe was like before becoming Spider - Man. Another could be a team - up between Miles and an older, more experienced Spider - Person from a different universe to face a new and powerful villain.
One idea could be that a new hero emerges during the Civil War and tries to find a middle ground between the two factions. They might have unique powers that allow them to communicate with both sides on a deeper level, and they end up uniting some of the heroes against a common, unexpected threat that was using the Civil War as a distraction.
One idea could be that the Justice League members have different views on how to handle a new superpowered threat. Some might want to use force immediately while others prefer a more diplomatic approach. This could lead to a split in the league, with each side believing they are in the right.
A possible plot could involve a misunderstanding. A powerful and mysterious magic item is found near the guild. Some members think it should be destroyed immediately as it might be cursed, while others believe it could be studied and used for good. The resulting conflict escalates into a full - blown civil war, with friendships and alliances being tested.
One idea could be that Spiderman tries to rebuild his relationships with the Avengers who were on different sides during the Civil War. He could start by reaching out to Iron Man, trying to understand his point of view better and also explaining his own actions.
