Well, in a lot of such fanfics, it often starts with Peter making a small mistake while being Spider - Man. Maybe he leaves behind some evidence that's a bit too obvious, like his school notebook with his name on it at a crime scene. The Avengers, being the sharp - eyed group they are, start to piece things together. Tony Stark might be the first to suspect something, using his high - tech gadgets to analyze the蛛丝马迹 (clues). Once they figure it out, they could either be super protective of Peter, seeing him as a young and inexperienced hero, or they might be a bit wary, not sure if they can fully trust this new - found Spider - Man.
In some versions, Peter's fangirling over the Avengers as Spider - Man gives him away. He might accidentally let slip some inside knowledge about the Avengers that only a big fan would know while chatting with them during a fight or a rescue mission. For example, he could mention something specific about Captain America's shield technique that he learned from studying the Avengers obsessively. This makes the Avengers curious and they start to dig deeper into Spider - Man's identity. Eventually, they find out it's Peter. Then it depends on the mood of the writer. They could write a heart - warming story where the Avengers take Peter under their wing and train him, or a more angsty one where Peter has to prove himself all over again to earn their trust.
Tony Stark would probably be both proud and a bit worried. Proud because Peter is this brilliant young mind who has managed to be a hero on his own, but worried because he's just a kid. He might start to hover over Peter more, offering him better tech and trying to mentor him more closely. Captain America would likely be very accepting. He sees the good in people and would be happy to have another brave soul on the team. He'd probably offer Peter some words of wisdom about using his powers responsibly. Thor might be a bit clueless at first. He doesn't quite understand the whole 'secret identity' thing as well as the others, but once he gets it, he'd be all for having Peter around. He might see Peter as a little warrior and be eager to train him in his own Asgardian ways.
Well, it could also happen that Peter's Spider - Man suit technology gives him away. Maybe the Avengers have some advanced tech - sensing equipment, and when Peter is around in his suit, it gives off some unique signals that the Avengers pick up on. So, they start to look into it and eventually figure out that Peter is Spider - Man.
The battle is intense and full of surprises. Spider-Man shows off his agility and web-slinging skills, while The Avengers use their teamwork and various powers to counter.
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.
One interesting storyline could be Spider - Man teaming up with the Avengers to fight a new super - villain that's a combination of different powers they've faced before. For example, a villain with the strength of the Hulk and the mind - control abilities of Loki.
Well, it could be an interesting idea. On one hand, the Avengers are a powerful group, and pitting them against Spider - Man could create some intense battles. It would also allow for exploring different power dynamics and relationships. However, it might seem a bit odd since Spider - Man is often seen as a hero among heroes. But if the fanfic has a good backstory, like some misunderstanding or an outside force manipulating the situation, it could work really well.
In many Avengers fanfics, Spider - Man's sacrifice can be a very powerful plot point. It often shows his selfless nature. He might sacrifice himself to save his fellow Avengers or the world from a great threat. This kind of sacrifice also adds depth to his character as it shows his growth from a young hero to one who is willing to give everything for the greater good.
Peter could use his knowledge of the Avengers' schedules. For example, he could avoid being Spider - Man in areas where the Avengers are likely to be patrolling at the same time. Also, he could disguise his voice when interacting with them as Spider - Man, so they don't recognize any similarities to Peter. He might also modify his web - slinging patterns slightly when around the Avengers to make it seem like a different style from what they might expect from a local hero.
One possible plot twist could be that Peter is in a situation where he has to save the Avengers secretly as Spider - Man. Maybe they are captured by a powerful villain and Peter, using his knowledge of the Avengers' base and their habits that he learned as a fan, manages to rescue them without revealing his identity. Another plot twist might be that Peter starts to leave little hints about his identity, like using a specific web - shooting style that he once wrote about in a fan blog when he was fangirling over the Avengers. And the Avengers start to suspect there's something familiar about Spider - Man but can't quite put their finger on it.
Iron Man is a great character to pair with Spider - Man. Tony Stark can act as a mentor to Peter Parker, providing him with new and advanced tech for his suit. They also have a fun dynamic, with Stark's sarcasm and Spider - Man's youthful exuberance.
