The team would then start to investigate what happened to Natsu. If it was an enemy attack, they would go after the perpetrator. Erza would be leading the charge in this regard, with her strong sense of justice and combat skills. They wouldn't let whoever did this to Natsu get away with it.
His friends would most likely try to heal him immediately. Wendy, with her Sky Dragon Slayer magic, could be the first to attempt to close his wounds and stop the bleeding. She has great healing abilities, so she would be crucial in this situation.
Well, in a fanfiction where Natsu is found bleeding out, it could be due to a number of reasons. Maybe he got into a really tough fight with a powerful enemy that he underestimated. In Fairy Tail, Natsu is often reckless in battle, so it's not out of the question.
Well, if Natsu asks Lucy out in fanfiction, it could change the whole dynamic of the Fairy Tail group. Their friends would probably be super supportive, especially Happy. They could start exploring new places not just for quests but also for romantic getaways. And Lucy might write a new story about their relationship in her diary.
Natsu could end up teaming up with some unexpected allies from Tartaros. Maybe there are some members who have a change of heart and decide to help Natsu fight against the more evil elements within their own organization.
She could be a key figure in an ancient prophecy. For example, the prophecy might state that only the son of a certain dragon - slayer mother (Natsu's mother) would be able to defeat a great evil that threatens the Fairy Tail world. This would set Natsu on a path to discover his mother's identity and fulfill the prophecy.
One possible plot could be that the guild goes into deep mourning. Gray might blame himself, thinking he could have protected Natsu. Lucy could be in a state of shock and disbelief, and she might start writing in her diary about all their adventures, as if reliving the memories to deal with the pain.
Natsu could also be deeply hurt. He values his friends highly in Fairy Tail. If betrayed, he might isolate himself, doubting his own judgment in trusting people. This could lead to a period of self - discovery where he tries to figure out how to trust again. For example, he might recall the times when his friends in Fairy Tail were truly there for him and use those memories to heal and grow stronger in the face of this betrayal.
In such a fanfiction, Natsu might have become much stronger. Maybe he has mastered new fire - based magic techniques. He could also have new relationships within the guild, like closer friendships or even a romantic interest.
Well, in fanfiction where Natsu leaves the guild, he could become a sort of lone wolf. He might travel to far - off lands to discover more about his dragon - slayer powers or his past. This could lead to him meeting new and powerful allies or enemies. Without the support of the guild, he would have to rely solely on his own strength and wits. It could also make him a more serious and hardened character, as he no longer has the safety net of his Fairy Tail family.
Natsu could bring a more fiery and passionate leadership style. He'd probably be more action - oriented than the previous masters. For example, if there's a conflict with another guild, he'd be the first one to charge into battle, leading by example.
If Natsu and Zeref join Fairy Tail in fanfiction, it would change the dynamic of the guild completely. The other members would have mixed reactions. Some might be distrustful of Zeref due to his past actions. However, as time passes, they could see the good in him. Natsu and Zeref together could attract a lot of attention from outside forces. Enemies might target Fairy Tail more because of their combined power. But also, they could inspire the guild to become even stronger, with everyone striving to keep up with their new powerful comrades.
