Well, one possible plot could be that during a big battle where the Avengers and Spiderman are fighting side by side against a powerful enemy like Thanos. Spiderman, being young and perhaps a bit over - eager, jumps into a dangerous situation without proper backup. He gets injured while trying to protect an Avenger, say Captain America. This could lead to a lot of guilt among the Avengers for not being able to protect him better and also Spiderman having to deal with his own physical and mental recovery.
The team might become more united in their goal to avenge Spiderman's injury. They could focus all their efforts on finding and defeating the one who hurt him. This could lead to some great teamwork moments where they combine their powers in new and creative ways. Also, characters like Black Widow could be more nurturing towards Spiderman during his recovery.
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 great 'Avengers and Spider - Man fanfiction' is 'The Friendly Neighborhood Avenger'. It combines Spider - Man's street - level heroics with the grandeur of the Avengers. It has an interesting plot where Spider - Man has to teach the Avengers some of his unique ways of dealing with small - scale threats while also learning from them about handling large - scale disasters.
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.
It depends on the type of fanfiction. In some darker or more angst - filled fanfictions, it is quite common as it adds drama. However, in more positive or team - building - focused fanfictions, it's not as common. These types of stories usually focus on the Avengers and Spiderman working together and getting along. So, it varies from one type of fanfic to another.
Spiderman might use his agility and web - shooting abilities. He could quickly web up Venom, restraining his movements and preventing him from attacking the Avengers.
The other Avengers would be devastated. Iron Man, for instance, might feel guilty as if he could have done something more to protect Spiderman. He might become more withdrawn and focus even more on creating better technology to prevent such tragedies in the future.
In some fanfiction, Spiderman might hurt the Avengers due to mind control. For example, if a powerful villain like Loki gets hold of Spiderman and forces him to fight against the Avengers, he could cause harm. Another possibility is a misunderstanding. Spiderman might be tricked into believing that the Avengers are a threat and act accordingly.
