In some fanfictions, Spiderman might die due to a miscalculation in his powers during the battle in Civil War. Maybe he tries to overextend himself to protect civilians or other heroes and gets caught in a cross - fire that his body can't withstand.
In the fanfic world, the public's reaction would be huge. Spiderman was a beloved hero. There could be mass protests against the superheroes and the Civil War in general. The remaining superheroes would have to deal with this public outcry while also mourning the loss of Spiderman. They might also start to question their own actions and the future of superhero - ing without him.
It would also have an impact on the public. Spiderman was a beloved hero. His death could lead to a loss of hope among the civilians. Some heroes might then feel the need to step up more to fill the void he left, while others might be too traumatized by his death to function properly in their heroic duties.
Well, one way could be that in the chaos of the Civil War, Spiderman might be caught in the crossfire between the two sides. Maybe he tries to stop a particularly violent clash and gets overpowered by the combined forces accidentally. Another possibility is that he's betrayed by someone he trusts on one of the sides, leading to his demise.
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.
There's a fanfiction called 'Young Spidey in Civil War'. It's really good because it explores Spiderman as a young and inexperienced hero in the complex situation of the Civil War. It shows his growth and how he tries to navigate the difficult political and moral landscape of the war between the Avengers.
There are a few significant deaths. One of them is Goliath, who is tragically killed during the battle. Also, some minor characters lose their lives, but their impact is relatively smaller compared to major ones.
