In fanfiction, the Avengers could capture Spiderman if they think he has fallen under the influence of a villain. Maybe they noticed some changes in his behavior or the way he uses his powers. They would want to contain him first and then try to figure out what's wrong and if they can help him break free from the supposed influence.
The Avengers might capture Spiderman in fanfiction because they suspect he has been involved in some activities that seem suspicious. For example, if there are some strange occurrences in the city that seem to be related to Spiderman's powers, but they don't understand the full context, they could take him into custody to figure things out.
One reason could be that they suspect him of being involved with a new villain's scheme without having all the facts. So they act preemptively and capture him.
In some fanfictions, the Avengers might hate Spiderman due to jealousy. Maybe Spiderman's new - found popularity or his unique abilities make some of the Avengers feel threatened. For example, if he gets more media attention or praise from the public, it could stir up envy among them.
Shield might capture Peter Parker because they see his superpowers as a potential danger. His abilities are extraordinary, and if misused, could cause a great deal of harm. So, they may want to keep him in check.
In some fanfiction, the Avengers' interrogation of Spiderman could be more hostile. For example, if the story is set in a darker universe, they might not trust him easily. In other stories, it could be more of a friendly 'check - in' that just looks like an interrogation on the surface. Maybe they just want to make sure he's handling his superhero duties okay.
Spiderman's super strength allows him to carry or support the Avengers if they are injured or unable to move on their own. His webs can also be used to bind villains, stop incoming attacks, or create safety nets for the falling Avengers.
The Avengers might capture Spider - Man if they suspect him of being involved with a new, unknown threat. For example, if there are strange crimes happening in the city and Spider - Man is seen at the scene every time, they could assume he's part of it.
The three Avengers could be Iron Man, Captain America and Thor. Iron Man could provide the high - tech gadgets and strategic thinking. Captain America would bring leadership and his combat skills. Thor with his godly powers like lightning and super strength would be a great addition. They would each have different interactions with Spiderman, for example, Iron Man might be like a mentor to him, while Thor could be more of a friendly rival in terms of strength.
One reason could be a misunderstanding. Maybe some events were misinterpreted, and the Avengers thought Spider - Man was involved in something bad. For example, if there were some crimes that seemed to have Spider - Man's fingerprints all over them, but in reality, he was being framed.
The rebels are a likely candidate. They've always been against the Empire and Vader is one of its most powerful enforcers. Capturing him would be a huge blow to the Empire and a great victory for the rebellion.
There's also 'Spiderman's Avengers Adventure'. This fanfic delves into what would happen if Spiderman had to lead the Avengers in a crisis situation. It's full of character development, especially for Spiderman as he steps up to the plate. The story has a great balance between his quippy nature and the seriousness of the situation.
