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.
Well, if Spider - Man died in a Civil War fanfiction, it could be that his death serves as a catalyst for the end of the war. His death might make both sides realize how pointless their fighting is. Maybe the heroes would then come together to honor his memory and try to make amends. His friends in the superhero community, like Ned if he knew about Peter's identity, would be heartbroken. And villains might take advantage of the situation, thinking the heroes are weakened without Spider - Man, which could lead to new threats emerging in the fanfiction world.
Spider-Man's age in the Civil War comics varies depending on the specific storyline and interpretation. Generally, though, he's around 18-21 years old.
In many fanfics, Spider - Man could get injured in the Civil War scenario. Maybe he's facing off against stronger opponents like Captain America or Iron Man and gets overpowered. His inexperience compared to the older heroes might lead to him making mistakes and getting hurt.
Spider - Man could stop the Civil War in the fanfic by appealing to the moral compasses of the heroes. He could remind them of their original purpose - to protect the innocent. By showing them how their fighting is actually harming the very people they swore to protect, he could make them stop. Also, his webs could be used in a creative way. Maybe he could create some kind of web - based barrier between the two fighting sides to physically stop them from attacking each other while he talks some sense into them.
In a fanfiction, Spider - Man could also die due to friendly fire. With the heroes split in the Civil War and the chaos of battle, it's possible that a misaimed attack from one of the heroes accidentally hits Spider - Man and causes his death.
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.
Well, if Spider - Man stops the Civil War in the fanfic, it could have a huge impact on the relationships between the characters. For example, Iron Man and Captain America's relationship might be mended more quickly. Spider - Man could use his charm and influence to make both sides see reason. He might also inspire other heroes to find a middle ground and come up with new ways to deal with the issues that led to the Civil War in the first place. And this could lead to new storylines where the heroes are stronger together, facing external threats more united.
