What could be the reasons for Natsu being hated in Fairy Tail fanfiction?

The end might be hated because it didn't tie up all the loose ends properly. In 'Fairy Tail', there were many sub - plots and relationships. If the fanfiction end fails to address these in a satisfactory manner, like leaving a potential romantic relationship in an ambiguous state or not fully explaining a character's growth, fans would be disappointed.

Maybe he got into too many fights. Natsu has a short temper and if there were other students in the academy who provoked him or if he was standing up for someone, he might have engaged in brawls that the academy doesn't tolerate. In a place like Fairy Tail Academy, they might have strict rules about student behavior regarding fighting.

One possible reason could be that he was wrongly accused of a serious crime within the guild. Maybe some powerful and influential members believed he was a threat and pushed for his banishment. For example, if there was a string of mysterious attacks and Natsu was framed as the culprit due to his often wild and uncontrollable nature in battle.

Perhaps they leave because of a disagreement within the guild. Maybe there's a new policy or a decision made by the guild master that they don't agree with. For example, if the guild decides to get involved in a war that they think is unjust, they might choose to leave rather than participate against their beliefs.

One possible reason could be a misunderstanding within the guild. Maybe some false information was spread about them, leading others in Fairy Tail to turn against them. Another reason might be a power struggle. If Natsu and Erza were becoming too powerful, some jealous members could have conspired to make it seem like they were betraying the guild. Or perhaps an outside force manipulated the situation to drive a wedge between them and the rest of Fairy Tail.

One possible reason could be a conflict with other guild members. Maybe there's a misunderstanding or a fight that makes Natsu feel he no longer belongs. Another reason might be that he has a personal mission that goes against the guild's rules or values in the fanfiction. He could also be framed for something he didn't do and, feeling betrayed, decides to drop out.

One possible reason could be a misunderstanding within the guild. Maybe someone spreads false rumors about Natsu, leading others to believe he's done something wrong. Another reason might be a power struggle. If there are those in Fairy Tail who envy Natsu's strength and popularity, they could plot against him to get him out of the way.

One possible reason could be a misunderstanding. Maybe Natsu is wrongly accused of a crime he didn't commit, like being framed for causing great harm to the guild. Another could be a dark magic influence. If some powerful dark magic gets into the guild members' minds, they might turn on Natsu without realizing it. Also, it could be a sacrifice situation where the guild believes sacrificing Natsu would save the rest of the world from a great evil.

One possible reason could be to seek new adventures. They might feel they've reached a point in Fairy Tail where they've done all they can and want to explore new magic and challenges elsewhere. For example, they could have heard of a far - off land with a different type of magic that they are eager to learn about.

One possible reason could be that he accidentally causes too much destruction during a mission. Maybe he loses control of his magic and wrecks an important place in the magical world, leading the guild to expel him as a form of punishment.
