Well, in this kind of fanfiction, there could be an epic battle at first. The Avengers, with their superpowers like Iron Man's high - tech suit and Thor's hammer, might see Batman as a threat or an unknown figure. Batman, on the other hand, would use his detective skills and his array of gadgets. Maybe they would start fighting but then realize they have a common enemy. For example, a powerful villain from the Marvel and DC universes combined could be causing chaos. Then they would team up, with Batman's strategic mind helping the Avengers plan their attacks better, and the Avengers' superpowers providing the brute force needed to take on the bad guy.
Iron Man and Batman might be the most likely to clash. Iron Man is all about high - tech and showing off his latest inventions. Batman, while also using technology, is more of a brooding, solitary figure. Iron Man might see Batman as a bit of a relic or too old - fashioned in his methods. Batman, in turn, could view Iron Man as a bit too flashy and irresponsible with his power. Their egos could get in the way of them working together initially.
Maybe he'll encounter a young genius student who becomes his sidekick for the time he's at school. This student could help him with his high - tech gadgets or offer unique insights into the school's problems. Also, he might run into the principal who is initially suspicious of him but later realizes his good intentions.
One idea could be that Batman, in his quest to fight crime in Gotham, discovers some sort of interdimensional rift that leads him to the world of The Avengers. He then has to team up with them to stop a common enemy that is using technology from both universes to cause chaos. For example, Loki could be teaming up with some of Batman's rogues gallery like The Riddler to create complex puzzles and illusions that are both magical and technological in nature.
Batman would fit in by being the ultimate strategist. The Avengers sometimes jump into action without a fully thought - out plan. Batman's meticulous planning would force them to be more organized. He could also provide a more grounded perspective. Many of the Avengers have superpowers and deal with large - scale threats from outer space or magic realms. Batman, coming from the streets of Gotham, would remind them of the importance of protecting the everyday people.
The Avengers might react in different ways. Steve Rogers would probably be polite but firm in getting to know Peter's boyfriend. He'd want to ensure that he was a good influence on Peter. Thor, on the other hand, might be a bit more boisterous. He could either be really friendly and enthusiastic, or his loud and powerful presence might accidentally scare the boyfriend a bit.
I think 'avengers meet the seven fanfiction' might be a fan - created story where the Avengers and the Seven cross paths. It could explore things like cultural differences between the two groups if they are from different fictional settings. For example, the Avengers' values from the Marvel world and whatever values the Seven hold. It might also show how their different abilities work together or against each other in various scenarios like a big battle or a mission to save a world that is in danger due to some common enemy.
Well, in this 'avengers meet frigga fanfiction', it could center around Frigga using her magic to help the Avengers in some way. She might be a key to solving a mystery that the Avengers are facing. For example, she could have knowledge about an ancient artifact that the bad guys are after, and she teams up with the Avengers to keep it safe. Also, there could be some emotional moments as the Avengers, who have lost so much, find a mother - like figure in Frigga.
Maybe they're just bored. After all their battles and saving the world, they need some entertainment. Batman fanfiction could be a new and different form of it.
If the Avengers watched Batman fanfiction, they would likely have a range of reactions. Hulk might not care much as he's more interested in smashing things. Black Widow, on the other hand, would analyze the characters and their relationships in the fanfic. Hawkeye might just shake his head at some of the wild ideas in the fanfiction. They would all bring their own unique perspectives based on their own personalities and experiences.
