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.
Well, in this fanfiction, Natsu is surely a main character given he's in the title. Since it's set in a high school in the Fairy Tail world, characters like Happy, Natsu's sidekick, would probably be there too. And considering the dynamics of Fairy Tail, other important characters like Mirajane, who could be working in the school cafeteria or something, and Elfman, might also be part of the story. And of course, there's a high chance that the main antagonist or group of antagonists would also be some characters specific to this fanfiction, perhaps some new villains in the high school environment.
In 'natsu the fairy tail high school badass fanfiction', Natsu is the central figure. However, it's reasonable to assume that his friends from Fairy Tail would play important roles too. So, Lucy, with her celestial spirit magic, could be a main character, helping Natsu out in various situations. Gray, with his ice - making magic, might be involved in some sort of rivalry or friendship with Natsu in this high school setting. And Erza, the strong and fearless female character, would most likely be there to keep order or be part of Natsu's adventures. There could also be new characters introduced that are unique to this high school - based fanfiction, like a popular girl or a nerdy boy who end up being part of Natsu's 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.
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.
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.
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.
Natsu is often a main character. He's known for his fiery personality and strong magic. Then there's Lucy, a smart and kind - hearted girl. Gray is also commonly seen, with his cool ice - magic and his sometimes - comical rivalry with Natsu. Erza is another mainstay, a strong and strict girl who is respected by everyone.
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.
Erza is often written about. Her strong - willed and no - nonsense attitude can be translated well into a high - school - delinquent - style story. She could be the enforcer or the protector of the group. Happy, Natsu's sidekick, can also be a fun addition. He might be the comical relief in the midst of all the delinquent - related drama. And then there's Wendy. She could be the innocent character who is befriended by the delinquent group and slowly changes them for the better.
