Captain America might be the main character. He represents the heart and soul of the Avengers in many ways. In this fanfiction, he could be the one leading the team through an emotional crisis, using his unwavering moral compass to guide them and protect the heart of the team and the world they are trying to save.
I think Spider - Man would make an interesting main character. He's young and has a different perspective compared to the more experienced Avengers. His journey of growing up and becoming a more integral part of the team could be a central theme in the fanfiction. He also has his own set of personal problems like school and his relationships which could add depth to the story.
A new superhero created specifically for the fanfiction could be the main character. This character could have a power that is a combination of different Avenger's powers, like being able to have super strength like Hulk and also fly like Iron Man. Their unique abilities would draw the attention of the Avengers, making them the center of a harem - like story.
Iron Man could be the main character. He could use his technological genius to enhance the wings. Maybe he creates a special alloy for the wings that can withstand extreme heat and cold, and also has built - in weapons. He would be constantly tinkering with the wings, trying to make them better, all while using them to fight off new threats.
Obviously, the cook would be one of the main characters. They could be a young and ambitious chef who has always dreamed of working in a place as exciting as the Avengers Tower.
Another possibility is Gaara before he met Naruto. He had a really tough childhood and was initially very cold - hearted, seeing others as tools or threats. His heart was like a frozen desert, until Naruto's friendship started to thaw it. In this fanfiction, they could explore more of his pre - Naruto state of a frozen heart and how it affected his relationships with others in the shinobi world.
The main character could be Hermione Granger. Since she is very intelligent and has a strong sense of justice, she could easily be re - imagined as a lawyer. She could use her vast knowledge of magic and her quick thinking to bridge the gap between the two worlds and help the Avengers out. For example, if there was a spell that was being misused in the Avengers' world, she could figure out how to stop it legally.
It could be Iron Man, Tony Stark's father is Howard Stark. So Tony would have a very emotional and complex relationship in this meeting. He might be the main character as he gets to know his father in a different way and learn more about his past.
Iron Man could be the main character. Since he's often seen as the brains behind many of the Avengers' plans, if they were wrong, it could be his plan that went awry. So the fanfiction could focus on him coming to terms with his mistake and trying to fix it.
Captain America could be the main character. Since he has a long - standing history with Hydra (in the sense of fighting against their evil), he could be the one leading the charge to uncover and stop the Hydra experiment. His strong moral compass would make for an interesting dynamic as he tries to save those affected by the experiment.
Captain America could be the main character. Given his leadership qualities, he would be the one to step up and set an example when it comes to using the rectal thermometer. He would be the one to calm everyone down and remind them that it's for the greater good. He might also have some internal struggle with the whole idea, being from a more modest time, but he would do it anyway for the sake of the team.
