Well, obviously Peter Parker/Spider - Man is one of the main characters. He's the central figure in the 'Far From Home' story, and in the fanfic, he'd likely be the main focus for a lot of the action and character development.
Well, the Avengers watching 'Spider - Man: Far From Home' in a fanfiction could lead to some really interesting scenarios. For instance, Tony Stark might be a bit critical in a fatherly way, comparing Peter's actions to how he would have done things. Captain America could be impressed by Peter's moral compass. And Thor might find Peter's high - school problems hilarious compared to his Asgardian adventures. It would be a great chance for the Avengers to bond over Peter's movie adventure.
One idea could be that the Avengers secretly follow Peter Parker during his European trip in 'Far From Home'. They want to make sure he can handle the new threats on his own but end up having to step in at a crucial moment. Another could be that they get caught in the same illusions as Peter and have to fight their own mental battles while trying to protect the civilians.
There's a fanfiction where the Avengers watch the trailer and then start making bets on what will actually happen in the movie. It's a really fun take on it. The banter between the characters is great, especially between Sam and Bucky. It's called 'Trailer Predictions: Avengers Edition' and can be found on Archive of Our Own.
Tony Stark would likely give a witty response. He might say something like 'This fanfiction has some interesting ideas, but it could use a bit more of my genius.' Steve Rogers would probably take it seriously and try to understand the different interpretations of the story. He'd be respectful of the author's creativity. Thor would be all for it, shouting 'This is a great tale! More, more!'
Well, Tony might be amused and offer some sarcastic comments. He'd probably point out the creative liberties taken in the fanfiction. Steve, on the other hand, would be a bit more reserved. He might be a bit confused at first about this new form of storytelling but would gradually see the charm in it. Thor would probably find it hilarious and might demand more stories like it, especially if there are epic battles in the fanfiction.
Black Widow could be a great focus. Despite her sacrifice, in fanfiction, she could have left behind some crucial information or skills that the remaining Avengers use in 'Far From Home'. Maybe she had some knowledge about the type of technology Mysterio is using or some combat techniques that are useful against his illusions. Her backstory and her relationships with the other Avengers could also add depth to the story.
One interesting plot twist could be that Peter Parker's identity as Spider - Man is revealed to the public in a much more dangerous way than in the movie. Maybe a villain uses some mind - control device on someone close to Peter and forces them to expose him at a really bad time, like during a big public event where all the Avengers are present.
One common theme is the relationship between Peter Parker and MJ. Fanfictions often explore their relationship further, like their adventures together outside of what we saw in the movie. For example, they might go on a road trip and face some new challenges.
In the fanfiction, certain Avengers might be a bit critical. They might think that Spider - Man is being a bit too naive in some situations, like when he trusts Mysterio too easily. However, they also understand that he's still learning and growing. So, they would probably be more focused on teaching him rather than scolding him. They could be planning to give him some special training or advice to make him more cautious in the future.
