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.
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.
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.
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, the plot could start with Darcy losing her glasses somehow. This event could be the catalyst for a change in her. As a Thor fan, she might see this as an opportunity to reinvent herself. She could start training with the Avengers, with an eye on impressing Thor. Maybe she gets into a tricky situation during a mission and Thor has to rescue her, which deepens their connection.
Well, it could be that Harry Potter uses his magic skills like the Patronus charm against Thor's lightning. Maybe Thor mistakes Harry's magic for some new Asgardian sorcery at first. And then they start to fight over some misunderstanding, like a magical artifact that Thor thinks is from Asgard but Harry knows is important for the wizarding world.
One idea could be that the Avengers find themselves magically transported to the wizarding world. Thor, with his Asgardian magic, might have an interesting interaction with the Hogwarts professors. Maybe they team up to fight a new, combined threat that is both magical and technological.
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.
In this 'naruto son of thor fanfic', the plot might revolve around Naruto learning about his new heritage as Thor's son. He could go on a journey to Asgard to understand more about his father's world. There, he might face challenges from the Asgardian gods who are skeptical of a half - human, half - Asgardian like him. And he has to prove himself worthy while still maintaining his ties to the Hidden Leaf Village.
One plot could be that the cat avengers are split into two groups due to a misunderstanding. One group believes that the other is working with a group of rats who are stealing cat food. As they fight among themselves, the real villains, a gang of raccoons, start to take over the town. Eventually, the cats realize their mistake and reunite. They then use their combined powers, like the flying cat to scout the raccoons' movements, the strong cat to fight them directly, and the invisible cat to launch surprise attacks, to drive the raccoons out of the town.
The plot might involve a new villain who hacks into their chatroom. So, the Avengers have to figure out how to stop this digital threat while also communicating within the chatroom to coordinate their efforts. They could be discussing their individual strengths and how to use them against this new enemy. For example, Captain America could be leading the conversation on strategy, while Black Widow provides intel she's gathered. Hulk might be there just being Hulk, with the others trying to keep him calm and on track. And all of this happening in the unique setting of a chatroom, which adds a modern and interesting twist to the typical Avengers story.
