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.
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.
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 fanfiction where Natsu is the founder of Fairy Tail, the guild's culture would likely be heavily influenced by him. Natsu is known for his impulsiveness and his love for a good fight. So, the guild might have a more aggressive stance towards challenges compared to other interpretations. His relationships with the other main characters would also be re - imagined. For instance, his relationship with Lucy could be more of a mentor - mentee relationship at first, with Natsu guiding Lucy on how to be a true Fairy Tail mage. Also, the guild hall might have been built in a location that has a special significance to Natsu, perhaps a place where he had a memorable encounter with Igneel. And the guild's rules might be more lenient in some aspects, because Natsu is not one for strict regulations, but rather values loyalty and camaraderie above all else.
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.
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.
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.
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.
One possible reason could be a past trauma. Maybe he witnessed something really horrible during a battle or an incident at school that shocked him so much he lost his ability to speak. For example, if he saw a friend in great danger and was powerless to help immediately, it could have had such a psychological impact on him.
One interesting plot point could be Natsu getting into intense battles within the academy. Maybe he has to face a new kind of dark magic user that challenges his skills in ways he hasn't experienced before.
One great fanfiction could be about Natsu facing an ancient and extremely powerful dark wizard alone. In this story, Natsu's dragon slayer magic reaches new heights as he discovers a hidden power within himself. Maybe it's related to his connection with Igneel that he hasn't fully tapped into yet. He uses his fire magic in ways that are more creative and intense, like creating a massive firestorm that not only burns but also has the power to nullify the dark wizard's magic.
