It's highly unlikely that the Avengers, as fictional characters in their own right within the Marvel universe, would actually sit down and read Spider - Man fanfiction. They are usually too busy saving the world or dealing with their own personal dramas. Fanfiction is more of a concept for the fans in the real world.
Well, in the official Marvel lore, we don't see the Avengers sitting around reading Spider - Man fanfiction. But if we think about it in a more fun, what - if way, characters like Natasha Romanoff might read it to better understand the public perception of Spider - Man. Since she's good at gathering intelligence and understanding people, she could use fanfiction as a way to gauge how the general public, especially the fans, view the friendly neighborhood Spider - Man. And who knows, maybe Peter Parker himself would be horrified or flattered to know that some of the Avengers might be reading fan - created stories about him.
Well, they might be really impressed with how Spider - Man has developed in this fanfiction. Maybe they'll cheer for his new moves or be shocked at the new villains he faces.
Well, in the official Marvel universe, there's no indication that they do. Fanfiction is more of a meta - concept created by fans outside the official canon. However, it could be an interesting idea for a crossover fan - made story where the Avengers stumble upon some TASM fanfiction, maybe as part of a light - hearted moment in a team - building exercise or something.
Tony would probably focus on the tech aspects. He might think Spider - Man's web - shooters could be upgraded in a certain way. Steve would look at the hero's values, seeing if he's staying true to what a hero should be.
They often react with shock and grief. Some might immediately go into a rage, seeking revenge on whoever caused Spider - Man's death. Others may be paralyzed by the sudden loss, unable to function for a while.
Well, maybe he's got some secret mission that he doesn't want the Avengers to interfere with. You know, like protecting a particular person or some crucial information that he thinks the Avengers might mess up if they get involved.
Another possibility is that the Avengers are being manipulated by a villain. The bad guy could be using false information to make the Avengers believe that Spider - Man is a danger. So they go after him without really knowing the truth.
One interesting plot could be that the Avengers are watching Spider - Man's adventures in the PS4 game world and they start to give him advice from their own experiences. For example, Iron Man might suggest new tech upgrades for his suit based on what he sees in the game.
One possible plot could be that the Avengers are so inspired by the trailer that they decide to create a new mission specifically for Spider - Man. They could see his potential in the trailer and want to test him in a real - life situation.
