Since I haven't read 'leaving the galaxy fanfic', it's difficult to name the exact main characters. However, they could be a diverse group. There might be a young and curious protagonist who is eager to explore the unknown. There could also be an older, wiser character who provides guidance during the journey. And perhaps there are some characters with special abilities that are crucial for the survival and success of the mission to leave the galaxy.
In this 'leaving the galaxy fanfic', a significant concept could be the redefinition of what it means to be 'home'. As the characters leave the galaxy, their perception of home changes. They might carry with them the memories and cultures of their galactic home, but also start to form new identities in the journey. Additionally, the fanfic could explore the scientific theories related to traveling beyond the galaxy, such as the implications of leaving the gravitational pull of the entire galaxy and how that affects time and space.
Star - Lord is an obvious choice. His dual identity as a human from Earth and a galactic hero gives a lot of scope for character exploration. You could write about his struggle to balance his two lives, or how his memories of Earth influence his decisions in the galaxy. Drax is also interesting. His quest for revenge and his unique way of seeing the world can be the center of an engaging fanfic.
Rey could be a main character as well. With her strong connection to the Force, she could be on a journey of discovery in the Milky Way, learning about new cultures and ways of life, and using her skills to help or hinder different factions depending on her perception of right and wrong.
There's no way to tell without reading the story. It could be a young person leaving their family, so the main characters would be the young person and their family members. Or it could be a character leaving a community, and the main characters would be that person and the key members of the community.
The main characters are Star - Lord, Gamora, Drax, Rocket and Groot. Star - Lord is the leader - ish type. Gamora is a skilled fighter. Drax is super strong. Rocket is a clever and sassy raccoon, and Groot just says 'I am Groot' but is very powerful and kind - hearted.
The main character is a college student. But there are also his friends, classmates, and people he meets during his various adventures.
I'm not entirely sure without reading the novel, but usually in such a story, there might be a protagonist who initiates the act of leaving the world behind. There could also be some supporting characters like a friend or a family member who either joins in or tries to stop the main character.
Since we don't have much information about the 'leaving the world behind story', the main characters could be people who are disillusioned with the current state of the world. They might be rebels in a sense, who are not satisfied with the social norms, political situations, or cultural values. So they take the initiative to leave the world behind, whether it's a physical departure or a mental break from the status quo.
I'm not entirely sure about all the main characters specifically, but usually there are a male and a female lead.
I'm not sure as the title doesn't give that away. It could be two star - beings, or perhaps an alien and a human who end up in the 'Cannibal Galaxy'.
