They often react with shock and grief. Some might immediately go into a rage, seeking revenge on whoever caused Spider - Man's death. Others may be paralyzed by the sudden loss, unable to function for a while.
Their dynamics would change a great deal. There would be a lot more tension. Some members might blame themselves or others. For example, Iron Man could be at odds with Captain America if they had different ideas on how to handle the situation.

One popular fanfiction might involve the Avengers feeling a deep sense of guilt and regret as they watch Spider - Man die. They could be haunted by their inability to save him. In some stories, this event might lead to a rift within the Avengers as they each deal with their grief in different ways.
It's highly unlikely that the Avengers, as fictional characters in their own right within the Marvel universe, would actually sit down and read Spider - Man fanfiction. They are usually too busy saving the world or dealing with their own personal dramas. Fanfiction is more of a concept for the fans in the real world.
Well, in the official Marvel lore, we don't see the Avengers sitting around reading Spider - Man fanfiction. But if we think about it in a more fun, what - if way, characters like Natasha Romanoff might read it to better understand the public perception of Spider - Man. Since she's good at gathering intelligence and understanding people, she could use fanfiction as a way to gauge how the general public, especially the fans, view the friendly neighborhood Spider - Man. And who knows, maybe Peter Parker himself would be horrified or flattered to know that some of the Avengers might be reading fan - created stories about him.
A possible plot is that Spider - Man gets caught in a time - related incident. For example, he could be trapped in a time loop that slowly drains his life force as he tries to break free. Eventually, he succumbs to it, and the Avengers are left to figure out how to prevent such a thing from happening again.
In the fanfiction, the Avengers would likely be devastated. Captain America might feel a sense of guilt for not protecting Spider - Man better. Iron Man could be filled with rage and vow to take revenge on whoever was responsible. Thor would probably be solemn and use his strength to seek justice. Overall, their reactions would be a mix of grief, anger, and determination.
The Avengers would be very concerned. Captain America would immediately take charge of the situation, trying to keep everyone calm while they assess Spider - Man's injuries. Iron Man would start scanning for the best way to treat him, using his high - tech equipment. Thor might offer some of his Asgardian knowledge of healing, if there was any. Black Widow and Hawkeye would be on guard, making sure there were no further threats while the team focused on Spider - Man.
Spider - Man would likely be confused at first. He respects the Avengers and can't understand why they are suddenly after him. He might try to talk to them, to explain that he's innocent. For example, he could swing up to Captain America and start pleading his case.
Spider - Man would probably be shocked at first. He looks up to the Avengers and being kidnapped by them would be the last thing he expects. He'd likely try to talk his way out, using his quick wit and charm. He might start by asking why they're doing this and try to convince them that they've made a mistake.
Spider - Man would be very confused. He would feel betrayed because he thought the Avengers were heroes he could trust. He could start by asking them why they are doing this. If they don't give him a satisfactory answer, he might try to escape in a sneaky way, using his spider - like abilities to find a weakness in their capture setup while still trying to reason with them.
