Natsu is surely one of the main characters as the title implies. There might also be other Fairy Tail characters like Lucy, Gray, and Erza. They could be Natsu's friends or classmates in this high school fanfiction.
It could be about Natsu being a really cool and tough character in a Fairy Tail high school setting in a fan - created story. Maybe it involves his adventures, his relationships with other characters from Fairy Tail in a high school context, like his friendships or rivalries.
Most likely Natsu would be one of the main characters. And probably Lucy, Gray, and Erza from Fairy Tail could also be main characters as they are often associated with Natsu in the original Fairy Tail series.
Obviously, Natsu would be one of the main characters. He's the 'badass' in the title. His fiery personality and powerful magic are likely to be central to the story.
I'm not sure exactly as it's a fanfiction. But it might be about Natsu in a high school setting in the Fairy Tail universe, being a badass, which could involve him getting into cool adventures, showing off his powers, and having some sort of unique relationships with other characters from Fairy Tail in this high - school - themed scenario.
Well, Natsu is the central figure as it's about him being a high school rebel. But in addition to his Fairy Tail friends, there could be some original characters created for this fanfiction. For example, there might be a strict principal or a group of rival students who become important characters. The story could revolve around Natsu's interactions with these characters, whether it's clashing with the principal over school policies or competing with the rival students in some sort of magical or non - magical contests.
Another plot could revolve around Natsu being the new kid at school and having to earn the respect of his classmates. He gets into various battles and challenges, not just physical ones but also magical duels of wits. His friends from Fairy Tail might visit the school from time to time to help him out or just to see how he's doing. And as he overcomes these challenges one by one, he gradually becomes a respected and feared figure at the school, all while still maintaining his fun - loving and loyal nature.
In this fanfiction, Natsu would likely bring his fiery and determined personality to the school environment. He might form new friendships or rivalries with other characters from Fairy Tail who are also at the school. Maybe he'd be part of a team for some sort of school - wide magical competition, showing off his skills and his loyalty to his friends.
Seilah is also a main character in this context. She has her own set of powers and a rather complex personality in the Fairy Tail universe, which can be further explored in fanfiction.
Lucy could be a main character. She was always close to Natsu in the original Fairy Tail. So when Natsu returns as an 'ex' and meets the guild again, she would likely play a big role in how he is received and in the development of the story.
Lucy is often paired with Natsu in many fanfictions. Their relationship can be explored in different ways in these fan - created stories. It could be a more romantic relationship than in the original series, or they could have a different kind of partnership, like being more equal in power or having different goals they pursue together.
