There's no way to know for certain without reading the novel. However, common character archetypes in such a story could include the hero - type character who is always ready to take on challenges, a sidekick who provides support and comic relief, and a mentor figure within the academy who guides the students on their adventures. There could also be antagonists in the form of rival students or faculty members with their own agendas.
Rose Hathaway is one of the main characters. She's a strong and feisty character in the vampire academy.
I'm not entirely sure, but usually there would be the dragonar students who are the central characters.
Finn and Jake are definitely popular choices. Finn's heroism and Jake's laid - back yet powerful nature make them interesting to write about in the academy setting. They can get into all sorts of adventures together and with their friends at the academy.
I'm not sure specifically as I haven't read it, but it could be the 'extra' student who is the protagonist. There might also be a strict headmaster or some mean - spirited classmates.
It's possible that there are multiple main characters. For instance, a group of students who band together to investigate the reasons behind the academy's ruin. They could each have different personalities and skills. One might be good at research, another at leading, and they all contribute in their own ways to either understand what happened or to try and reverse the situation.
I'm not sure specifically as I haven't read the novel, but they could be the students who are trying to survive in the academy.
The Umbrella Academy is filled with distinct main characters. Luther, the strongman, is often at the forefront of the action. Klaus, with his rather spooky ability to communicate with the dead, adds an element of the supernatural. Vanya, whose power is initially hidden but then becomes a major force. Diego, the knife - throwing expert, and Allison, who can manipulate people with her words. Their interactions, both positive and negative, drive the story forward as they face various challenges together in the world of the graphic novel.
It's likely that there are Jedi students from different species and backgrounds. One might be a brash and headstrong character, always eager to prove himself in combat. Another could be a more studious and reserved Jedi, focused on the study of the Force's deeper mysteries. And there could be an older, experienced Jedi who serves as a mentor and guide for the younger ones, having seen many things in his long years at the academy.
Some of the main characters include Ash Blake, a talented student at the academy.
I don't know since I haven't read it. But it could be students, teachers, or the principal.
