It's hard to say without reading the novel, but perhaps there is a character who has experienced some kind of trauma in the past. This character could be one of the main ones, and their journey to overcome that trauma and become a hero could be a central part of the story. There might also be a character who is really good at a particular skill, like fighting or problem - solving, and they play an important role in the group of potential heroes.
I don't know the exact 'we can be heroes story', so I can't say for sure who the main characters are. They could be regular people like a school teacher, a construction worker, and a young student who all find themselves in a situation where they need to be heroes.
The main theme could also be about friendship and camaraderie. In stories where the characters are on a path to be heroes, they often rely on their friends. In this novel, perhaps the characters support and inspire each other to reach their heroic potential. They might work together to overcome obstacles, and through that, the bond of friendship is strengthened and becomes a key part of the story.
Maybe some new characters who were inspired by the Avengers but have their own unique powers. They could be from different parts of the world or even from other planets. One might be a girl with the power to control nature and she joins the new generation of heroes in 'The Avengers Heroes of Tomorrow Fanfiction'. Another could be a young man who has super speed and was inspired by Quicksilver. There could also be a character who has psychic abilities and he was drawn to the Avengers' cause of protecting the world.
Definitely Iron Man's protege. Maybe a young genius who has been learning from Tony Stark's technology and has developed their own unique suit. They could be a key character in leading the new generation of Avengers.

Since we don't have much information, it's hard to say for sure. However, in many hero - themed novels, there are often characters who start from humble beginnings and rise to become heroes. So there might be a young protagonist with a special destiny, along with some side characters who support or oppose him on his journey.
I don't know specifically as I haven't read this novel. But likely, the King of Heroes himself is a main character. There may also be his allies and enemies.
I'm not sure exactly, but probably there are students who are the main heroes.

They would probably have distinct personalities and skills that they use to face the various challenges in the story.
