Perhaps in the fanfic, the Elementals are actually being controlled by an even bigger bad guy that was hiding in the shadows all along. So when the Avengers and Spider - Man think they've defeated the main threat, they find out there's this whole other level of danger. It would completely change the dynamic of the story and force them to come up with a new plan of action.
Another plot twist could be that Mysterio is not actually dead. He fakes his death and teams up with a different group of villains. He uses his illusion - creating technology to cause chaos and make the Avengers and Spider - Man doubt their own senses. This would add a whole new layer of mystery and danger to the fanfic.
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 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.
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.
A really cool plot twist could be that the Hogwarts founders are not as dead as everyone thought. They have been in a sort of magical stasis far from Hogwarts. Harry stumbles upon them during his travels very far from home. They have different views on how magic should be used compared to modern wizards. Harry then has to decide whether to side with the founders' old - fashioned ways or stick to what he has learned at Hogwarts, all while being in a strange and unfamiliar place.
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.
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 possible fanfiction could be where the Avengers are gathered in the living area of the compound. They watch the trailer with a mix of excitement and concern. Tony Stark might be making sarcastic comments throughout, like 'Well, looks like Peter's getting into more trouble without me.' Natasha could be analyzing every frame for potential threats. Another could be a fanfiction where the younger Avengers, like Shuri and Peter, are overly excited and keep pausing the trailer to discuss their favorite parts.
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 interesting plotline could be the Avengers having to deal with alternate versions of themselves that are brought into their universe during the events of No Way Home. It could lead to some really cool team - up and fight scenes.
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.
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.
