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 great fanfiction could be about Spider - Man's internal struggle during the events of 'Captain America: Civil War'. He's a new addition to this complex world of superhero politics. He might be initially excited to be part of the fight, but then starts to question the motives of both sides. Maybe he tries to find a middle ground, using his unique perspective as a young hero who hasn't been jaded by years of superhero rivalries.
One idea could be an OC who is a scientist caught in the middle. They could be working on a project that both sides think will give them an edge. For example, the OC might be developing a new type of energy source that could power super - weapons. Another plot could involve an OC with the power to manipulate emotions. They try to use their power to calm the situation between the two factions but end up getting caught in the crossfire. A third idea is an OC who is a journalist trying to expose the real reasons behind the civil war, which are more complex than just the superhero registration act.
There are some great storylines in Civil War fanfiction involving these two. For example, there's a story where Spider - Man's identity is at risk during the Civil War and Captain America helps protect him. This shows a different side of their relationship, more of a comrades - in - arms kind of bond. Another interesting one is when Spider - Man uses his intelligence to come up with a solution that could end the Civil War, and Captain America is the one who helps him implement it, highlighting their cooperation and mutual respect.
Well, in many Civil War fanfictions, Spider - Man and Captain America's interactions are really interesting. Spider - Man's admiration for Cap is clear. He's like a star - struck kid at times. And Captain America, he's kind of like a mentor figure who isn't quite sure what to do with Spider - Man. Their relationship can range from friendly rivalry to a more mentor - mentee thing, depending on how the author writes it.
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.
One idea could be exploring the perspectives of the minor characters during the conflict. For example, how an ordinary citizen in Sokovia feels about the heroes' actions. Another could be a what - if scenario where Steve Rogers and Tony Stark managed to resolve their differences before the big fight. Maybe a story about a new superhero who emerges during the civil war and tries to mediate between the two factions.
One idea could be exploring how the fractured Avengers try to regroup on their own. For example, Captain America could be leading a small, underground team that focuses on helping those affected by the Sokovia Accords in a more discreet way. Meanwhile, Iron Man might be working with the government to create a new, more controlled version of the Avengers.
One interesting development could be the rebuilding of relationships. For example, Tony Stark might try to reconcile with Steve Rogers in some fanfictions. After such a huge rift, seeing them slowly come to terms with each other again can be really engaging.
One interesting reaction could be from the perspective of ordinary citizens. They might be terrified and confused, seeing their heroes fighting each other. For example, in some fanfictions, they start to question the reliability of superheroes.
Another plotline might involve characters who were on the sidelines in the movie having a more prominent role in the fanfiction. For example, a minor character could have the key to resolving the conflict between Captain America and Iron Man. They could use their unique perspective or abilities to bridge the gap between the two factions.
