It could be really cool. Maybe they'd be dealing with typical high school stuff like exams and bullies while also having to hide their superhero identities. For example, Iron Man could be the super - smart kid in the science club who secretly builds high - tech gadgets in his garage.
One idea could be that the Avengers are all new students in high school. Iron Man could be the super - smart tech - geek who's always building cool gadgets in the school's science lab. Captain America might be the new transfer student who has a hard time adjusting to modern high school life but quickly becomes popular for his sense of justice. Thor could be the jock - like character who's a bit clueless about normal high school stuff but is really good at sports. And Black Widow could be the mysterious girl who everyone is a bit afraid of but is actually really kind.
Black Widow might be the most popular. She has a mysterious allure, is highly skilled in combat and espionage, and she could be the cool, confident girl that everyone wants to be friends with or be like. She'd also be very intelligent and able to handle any social situation with ease.
One idea could be that the Avengers are all students with different cliques. Iron Man could be the rich, popular kid who is also a genius in tech class. Captain America might be the new transfer student who tries to uphold old - fashioned values like honor and integrity in the high - school setting. Thor could be the exchange student from a far - off land, trying to fit in while also being super strong and a bit clueless about modern high - school norms.
One popular plotline could be Loki being the new student in high school where the Avengers are also students. Loki might initially try to cause trouble, like pranking the other students or trying to steal something important for a school event. Another plotline could involve a school competition where the Avengers and Loki are on opposing teams, and they have to learn to work together in the end. And there could also be a plot where Loki has a secret crush on one of the Avengers and tries to hide it while still being his mischievous self.
Probably Iron Man would be popular. He'd be the rich, smart kid with all the cool gadgets. Captain America would also be well - liked. His sense of justice and leadership would make him a respected figure among students. And Black Widow would be popular among the boys for her charm and mystery.
A cool plot for 'avengers high school au fanfiction' might involve a mystery. Maybe there are strange happenings in the school like objects floating around mysteriously. Wanda Maximoff could be the one who initially notices and tries to figure it out with the help of Vision. Meanwhile, Black Widow could be the popular girl who is secretly a spy, investigating a possible threat to the school from the inside.
I think Captain America would be really popular. He has that classic good - looks and a strong sense of right and wrong. He'd be the kind of guy who stands up to bullies and is always there to help others. In high school, those are qualities that would make him well - liked. Also, his leadership skills would probably make him a natural fit for student council or leading group projects.
A very common pairing is Loki and Thor. In a high school setting, Thor could be the popular jock type while Loki is the more brooding, artsy kid.

She might be the one to see through Loki's tricks and they could have a sort of cat - and - mouse relationship that slowly turns into something more. And of course, Loki and Tony Stark could be paired up. Stark's sarcasm and Loki's mischief would make for some great banter.
