natsu creates a dark guild fanfiction

Well, one possible plot could be that Natsu, after some sort of betrayal in Fairy Tail, decides to create his own dark guild. He might gather some disgruntled mages who also feel wronged by the mainstream guilds. Their goal could be to change the magic world's power structure in a more radical way, using darker forms of magic that are usually shunned. For example, they could explore ancient and forbidden magic spells to gain an edge over other guilds.

In this fanfiction, the characters would have to adapt to a more cutthroat environment. Natsu's friends from Fairy Tail who might join him in the dark guild would struggle with their new identities. They would have to learn to use magic in more aggressive and unorthodox ways. Their moral compasses would be tested as they engage in activities that are considered 'dark' in the magic world. Some might even have a complete character transformation, going from good - natured mages to feared members of the dark guild.

He might lose his friends at Fairy Tail. Since Fairy Tail is all about friendship and light, joining a dark guild would put him at odds with his former comrades.

In some fanfictions, Natsu could be framed by a dark guild as a traitor to Fairy Tail. The dark guild spreads false rumors and evidence, causing Fairy Tail to turn against him. Natsu then has to prove his innocence while also taking on the dark guild that started it all. This would lead to a lot of internal conflict within Fairy Tail and also intense battles between Natsu and the dark guild members.

His character could become more conflicted. He has to balance his old values from Fairy Tail with the new, darker ones of the guild he joined.

Emotionally, Natsu could become more empathetic. If he meets characters in the dark guild who had a difficult past that led them to the dark side, he might start to see things from their perspective. This doesn't mean he would support their actions, but he would understand them better. For example, if there's a character in the dark guild who was orphaned and turned to dark magic for survival, Natsu might feel sympathy for them and try to offer an alternative path rather than just attacking them. This would show a more mature and compassionate side of his character that wasn't as prominent before.

There could be some new characters too. Maybe a young orphan ninja who looks up to Naruto as a hero and wants to learn from him. There could also be a ninja from a small, less - known village who heard about Naruto's guild and saw it as an opportunity to gain more power and knowledge. And perhaps an outcast ninja who was shunned in their own village but Naruto gives them a chance in the guild because he believes in second chances.

The guild could be a place for ninjas from different villages to come together. Naruto, believing in unity among all ninjas, creates a guild that accepts members regardless of their village origin. This would cause some initial friction as old rivalries and suspicions surface. But Naruto, with his charisma and determination, would work towards building trust among the members. The guild's main goal could be to fight against a new, greater threat that endangers all the ninja villages, and they would need to put aside their differences to succeed.

Erza would be more composed. She would understand Natsu's reasons to a certain extent. However, she would also see the importance of the guild unity. So she would try to balance between respecting Natsu's decision and finding a way to make him come back if possible. She might send out some members to keep an eye on Natsu from a distance.

Well, one possibility could be that Natsu leaves the guild because of a personal mission. Maybe he discovers a dark secret about his past that he believes can only be solved alone, so he leaves Fairy Tail to find out the truth without putting his friends in danger.
