One possible plot could be that Natsu discovers a magic that allows him to sing and this singing has an effect on a snow fairy. Maybe his song can heal the snow fairy or break a curse on it.
Sorry, I'm not sure of a specific natsu sings snow fairy fanfiction off the top of my head. You could try searching on fanfiction websites like Archive of Our Own or FanFiction.net.
Natsu is likely to be a character with a passion for singing, or at least for Asuka, which drives him to sing. Asuka might be a character who is in need of something that Natsu's singing can provide, whether it's emotional support, love, or protection. They are the two main figures around which the fanfiction's plot would be built.
It could be about Natsu using his singing to express his deep feelings for Asuka. Maybe he sings to comfort her during a difficult time or to celebrate a special occasion in their relationship.
Well, Natsu is known for being impulsive and enthusiastic. So his singing would be similar in that it would be very spontaneous. He might not follow all the rules of music but rather sing in a way that comes straight from his heart. His singing could have a bit of a rough edge to it, just like his personality which isn't refined but is full of charm.
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.
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.
One great fanfiction that delves into Natsu's memories might be titled 'Natsu's Hidden Past'. In it, the author could explore his early days in Fairy Tail, his relationship with Igneel, and how those experiences shaped the person he is today. It might show how he learned to control his dragon slayer magic and the friendships he formed along the way.
