In fanfiction, Natsu's family often gets explored in various ways. Some fanfictions might focus on his relationship with Igneel, his dragon father. They could create scenarios where Natsu discovers more about his past and his family's heritage. It gives fans a chance to delve deeper into Natsu's character by looking at his family ties.
The theme of legacy also pops up a lot. Natsu's family, especially his dragon father Igneel, had a certain legacy. Fanfictions may explore how Natsu lives up to or breaks away from that legacy. Additionally, the theme of family secrets is quite popular. There could be hidden aspects of his family that Natsu discovers, which changes his perception of his family and himself.
Their family dynamic would likely be full of energy. Natsu's exuberance and Erza's strong - willed nature would create a lively household. Natsu would bring a sense of fun and adventure, while Erza would enforce discipline and order when needed.
Yes, in a lot of Fairy Tail fanfiction, Natsu can be overpowered. Writers often like to amp up his powers for more exciting storylines. For example, they might give him new fire - based abilities or make his existing ones even stronger to defeat more powerful foes.
In fanfiction, Natsu's age can vary greatly. Some authors might keep him at his canonical age from the original Fairy Tail series, which is around 17 - 18 years old at the start. However, in alternate universe fanfictions, he could be older or younger depending on the plot. For example, in a time - travel based fanfic, he could be much older if the story takes place far into the future or much younger if it goes back to his childhood days.
Often, it could be because of a false accusation. Maybe someone framed Natsu for a crime he didn't commit, like stealing a powerful magical artifact from the guild. So, to maintain peace and order, the guild leaders had no choice but to banish him.
One great storyline could be that Natsu discovers he has a long - lost relative who is in danger, and Lucy helps him find and protect this family member. It could involve a journey to a mysterious place filled with magical creatures that they have to face together.
Lucy could be a main character. She was always close to Natsu in the original Fairy Tail. So when Natsu returns as an 'ex' and meets the guild again, she would likely play a big role in how he is received and in the development of the story.
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.
In fanfictions like this, the character development of Natsu within the context of Sabertooth is interesting. He could learn new magic techniques from them or teach them his own unique brand of Fairy Tail spirit. It might also explore how the different cultures of the two guilds clash or blend.
