Well, in some fanfics, it could be a power struggle within the team. Spiderman might have new powers or knowledge that the other Avengers are jealous of or afraid of. So, they might take actions that end up hurting him, like trying to isolate him or directly attacking him in a fit of rage or fear.
There could also be a situation where Spiderman is framed for something he didn't do. The Avengers, believing the false evidence, might go after him. In these fanfics, it often shows the darker side of the Avengers and how quickly things can go wrong in the superhero world. It also gives an opportunity to explore Spiderman's character as he deals with being hurt by his heroes.
One reason could be a false accusation. If Spiderman is wrongly accused of a crime by the Avengers or someone within the Avengers' circle, he might feel betrayed and lash out at them. He's just a young hero, and such a false accusation could really make him angry.
One common theme is betrayal. Spiderman feeling betrayed by the Avengers who he looks up to. It could be that they don't trust him or believe in him like he thought they would.
One reason could be to explore the darker side of the characters. Some fans like to see how the Avengers could be pushed to their limits and do something out of character, like hurting Tony as a teenager. Another reason might be to create a more angsty and emotional story, with Tony as a victim and the Avengers as the antagonists, which can add a lot of drama.
One interesting aspect could be how Spider - Man's agility and street - level skills blend with the Avengers' more high - powered abilities. For example, his web - slinging could provide a unique form of transportation or capture for the team during a big battle against a powerful villain like Thanos. He could also use his spider - sense to detect threats that the other Avengers might miss.
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.
I'm not sure there are many 'Avengers hurt teenage Tony' fanfics that are considered 'worth reading' in a positive sense. Usually, such a plot involves dark and often out - of - character scenarios.

Captain America sees Spiderman's pure heart and starts to mentor him. Thor is amused by Spiderman's quips and they form a unique bond. The Black Widow and Hawkeye also play important roles in showing their love and care for Spiderman.
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.
