Well, in the official Marvel universe, there's no indication that the Avengers sit around watching Thor fanfic. Fanfic is more of a thing for fans in our world, not something the characters themselves would engage with in the main storylines.
One possible scenario in a fanfic could be that Thor gets injured during a battle with a powerful new enemy in the Avengers. Maybe he's facing an enemy with some sort of dark magic that can penetrate his Asgardian defenses. His fellow Avengers then have to figure out how to help him recover while still fending off the threat.
Well, perhaps Thor is injured while on a solo mission for the Avengers. He might be exploring an ancient ruin in search of a powerful weapon to help the team, but there are hidden traps. One such trap injures him severely. His injury could then be a catalyst for the other Avengers to learn more about the place where he got hurt and also about the weapon he was after.
It would be quite a strange situation. Maybe they'd be amused or confused. For instance, if they read some out - of - character fanfic, they might be really puzzled. Like if Thor was depicted as a coward in the fanfic, his fellow Avengers might have a good laugh or be a bit shocked.
It could be a prank gone wrong. Maybe Loki or another mischievous character played a trick on Thor that involved some sort of potion or spell that made him vomit. This would add an element of humor and sibling rivalry to the fanfic.
One popular 'Avengers Thor and Loki fanfic' story could be about their childhood adventures on Asgard. It might explore how their relationship developed from a young age, with Thor being the more outgoing and Loki the more mischievous one. Another could be a story where they have to team up against a new, powerful enemy in the Marvel universe that neither can face alone. There are also fanfics that focus on their reconciliation after a big fight, delving into their complex emotions towards each other.
Another idea is that Thor used his powers in an extreme way. For example, he summoned a huge amount of lightning and it drained his energy. This energy drain could have had an impact on his physical well - being, including making him nauseous and causing him to vomit. It could be a way to explore the limits of his powers and how they can have negative consequences on his body.
