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.
The fanfiction might see Natsu using his fire - based dragon slayer magic in creative ways to combat the dark magic of Tartaros. He could create new fire - based attacks or combine his magic with the environment in Tartaros to gain an advantage. For instance, if there are underground lava flows in Tartaros, Natsu could draw on that energy to boost his attacks.
A possible plot in this fanfiction could be that Tartaros has a plan to use Natsu's dragon slayer magic for their own evil purposes. Natsu has to fight not only to protect Fairy Tail but also to prevent his own power from being misused. This would put him in a very difficult situation and force him to make tough decisions.
One possible aspect of a Fairy Tail Natsu and Tartaros fanfiction could be Natsu's battle against the powerful foes in Tartaros. He might face new and terrifying enemies that test his limits. His dragon slayer magic would be put to the extreme, and perhaps he discovers new powers along the way.
One great 'Fairy Tail Tartaros' fanfiction is 'Tartaros' Redemption'. It focuses on a Tartaros member who starts to question their evil ways after interacting with Fairy Tail members. It has some really interesting character development and a unique take on the relationship between the two groups.
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.
Another reason is the large and passionate fan base of 'Fairy Tail'. Fans love to create their own versions of the Tartaros story. They can introduce new magic, new relationships, and new plotlines. The fanfictions often provide a fresh perspective on the well - known Fairy Tail universe, which is always exciting for both the writers and the readers.
Well, if Natsu adopted a child in fanfiction, it could be really interesting. The child would probably grow up to be strong, just like Natsu. Natsu would teach the child how to fight and use magic. And the child would also learn about the importance of friendship from Natsu and the rest of the Fairy Tail guild.
In this kind of fanfiction, the kid might have some unique abilities. Since Natsu is a dragon slayer, the kid could have an enhanced form of dragon slayer magic or a combination of different magics. For example, the kid could have the ability to not only use fire like Natsu but also manipulate wind to make the fire more powerful.
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.
In some fanfictions, if Natsu kidnapped Lucy, it could be a comical situation. Natsu might do it out of his own strange sense of protecting Lucy in an overzealous way. Maybe he thinks there's a danger that only he can keep her safe from, and his impulsive nature leads him to this 'kidnapping' which is more like a forced protection.
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.
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.
