How can I write a good serious Natsu fanfiction?

First, know the characters well. For Natsu, understand his fiery personality, his loyalty to friends. For the fem end part, define the characteristics clearly. Then, create an engaging plot. Maybe start with a conflict that involves both, like a threat to the fem end world that only Natsu can help with.

First, you need to have a clear understanding of the characters. Know Natsu's personality, his likes and dislikes. For the 'futa' aspect, be careful how you introduce and handle this concept in a way that fits within the context of the story. Also, focus on creating a strong plot that involves the female character in an interesting way.

First, know the original Percy story well. This gives you a base to build on. Then, think of a unique concept like 'What if Percy had a different power?'. Outline your story with a beginning, middle, and end. For example, start with Percy facing a new problem, develop the plot in the middle with his attempts to solve it, and end with a resolution. Also, create interesting new characters or expand on existing ones.

Create an engaging plot. You could start with a problem like Natsu getting separated from his guildmates in the Tower of Heaven. Then, introduce new challenges and characters as he tries to find his way out. Maybe he has to face a series of magical traps or encounter a powerful enemy that is guarding a secret within the tower. Also, add some emotional depth. For example, Natsu could be haunted by memories of his past related to the tower, which would add more layers to the story.

To write a great 'natsu x harem fanfic', start with a strong concept. Maybe it's a world - building concept where Natsu's harem is part of a special society. Develop the relationships gradually. Don't rush into the romantic parts. Let the characters interact in different situations, like during a battle or while solving a mystery. Also, add some twists and turns to keep the readers engaged. For example, a member of the harem might be secretly working against Natsu at first but then have a change of heart.

One popular 'natsu gets serious fanfiction' could be 'Natsu's True Power Unleashed'. In this fanfic, Natsu faces a powerful dark wizard and his serious side emerges as he battles to protect his friends and the guild. It shows a more determined and strategic Natsu.

To write a 'natsu is cheated on' rated M fanfiction, start with a strong outline. Outline how the cheating occurs, who the cheater is, and how Natsu discovers it. For the rated M part, if you want to include mature themes like sexual content, make sure it's done tastefully and in line with the overall story. Also, focus on the emotional turmoil Natsu will go through.

First, you need to understand Natsu's character well. Think about what could realistically push him towards the dark side. It could be a great loss, like the death of a very close friend. Then, plan out how this change will affect his relationships. For example, will he still care about Lucy in the same way? Next, create a new conflict that is related to his dark state. Maybe the guild has to decide whether to fight him or try to save him.

A third theme could be self - discovery. As Natsu gets serious, he may also discover new aspects of himself. Maybe he realizes he has more power within him than he thought, or he discovers a different way of thinking about his role as a dragon slayer. This can lead to some interesting character arcs in the fanfiction.

Another way is to ask in anime - related forums or groups. People there are often fans of natsu and lucy too and can recommend some great fanfiction they've read. You can also check out blogs dedicated to Fairy Tail (the anime they're from), as they sometimes feature reviews or lists of good fanfiction about these two characters.
