In fanfics, the Avengers can take care of Peter in many ways. They could share their own experiences with him. Thor could talk about his battles and how he overcame difficulties, which would inspire Peter. They can also help him with his identity as a superhero. Maybe Doctor Strange uses his magic to show Peter different versions of himself and how to choose the right path. And of course, they can just be there for him as friends, having movie nights or sharing meals together.
One great 'Avengers take care of Peter' fanfic could be where the Avengers teach Peter different combat skills. For example, Tony Stark might show him advanced tech - based fighting moves. Another could focus on the emotional support they give him. Maybe after a tough mission, Natasha Romanoff helps Peter deal with the trauma. And then there are those where they take care of his daily needs, like Steve Rogers making sure he eats well.
One possible plot could be that the Avengers find a weakened Loki after a battle. They decide to take care of him not out of trust but to keep an eye on him. Thor is conflicted as he wants to believe his brother can change. They nurse Loki back to health, and during this time, Loki starts to see the Avengers in a different light, leading to some comical and heart - warming moments as he tries to fit in without losing his mischievous charm.
Thor's relationship with Loki would likely become more complex. He'd be glad his brother is being cared for but also worried about Loki's true intentions. The Avengers, like Tony, might start to see Loki as more than just a villain. They could develop a begrudging respect for his intelligence. For Loki, he might start to feel a sense of belonging, which is something he's never really had. This could soften his attitude towards the Avengers.
It could also be due to jealousy. Peter might be getting too much attention from the public or other superheroes. His youth and new - found popularity could make the more established Avengers feel overshadowed, leading to feelings of resentment towards him.
It could be that Peter's immaturity showed in a crucial situation. He might have been over - confident and tried something really risky without thinking it through. The Avengers, being more experienced, would be frustrated with his recklessness and thus yell at him. They want him to learn and grow, but his actions might have been too much to tolerate at that moment.
He might also get angry. Peter has a strong sense of justice. If he feels that the Avengers are being unfair, he could stand up to them. He'll use his quick wit and his powers to show that he's not going to be pushed around easily.
Iron Man would be a likely candidate. He's already shown a sort of father - figure - like relationship with Peter in the movies. He can offer Peter high - tech resources, valuable advice on being a superhero, and also teach him about responsibility in a more modern way.
