One great 'Fairy Tail Dragon Slayer Fanfic' is 'The Dragon Slayer's Ascent'. It really dives into the growth of the dragon slayers in a unique way. It shows their struggles not just with their dragon powers but also in their relationships within the Fairy Tail guild. Another one is 'Dragon Slayers United' which focuses on how the dragon slayers work together against a common enemy that is far more powerful than any they've faced before.
One common trait is their determination. They are set on mastering their lightning dragon slayer magic and becoming stronger. They might practice day and night to improve their skills. Another trait is their loyalty to Fairy Tail. Even if they face difficulties or misunderstandings, they stay true to the guild. And they usually have some sort of mark or symbol related to lightning on their body, which could be a sign of their connection to the lightning dragon slayer magic.
One idea could be to create an OC (Original Character) who is an Element Dragon Slayer with a unique element, like shadow. The fanfiction could start with the character's discovery of their powers in a small, forgotten village. They then embark on a journey to find their dragon parent, facing various challenges along the way, including battles with dark guilds who want to use their power for evil.
Start with her origin. Decide if she was raised by a dragon or found dragon - slaying powers on her own. If she was raised by a dragon, think about how the dragon's teachings and values influenced her. For example, if the dragon was a kind and wise one, she might have a strong sense of justice. If she found the powers on her own, it could be through an ancient artifact or a mysterious encounter.
Well, if we consider Lucy as a Dragon Slayer in fanfiction, her magic could be really different from the traditional ones. Maybe she'd have a connection to a celestial dragon, which would be so cool. It would combine her existing celestial spirit magic with the new dragon slayer powers. She could use the stars as a source of power, similar to how other dragon slayers use elements, and it would be a fresh take on her character.
One thing that makes a 'Fairy Tail Dragon Slayer Fanfic' stand out is the world - building. If it expands on the already rich world of 'Fairy Tail' and gives more details about the dragon slayers' place in it. For instance, exploring the history of the dragons and how they chose their slayers. Another factor is the emotions. When a fanfic can make you feel the anger, joy, or sadness of the dragon slayer characters, it really draws you in. Also, if it has some unique twists on the existing 'Fairy Tail' lore, like a different origin for the dragon slayer magic, it can be very appealing.
One idea could be to focus on the male OC's origin. Maybe he was found as an orphan by the ice dragon in a frozen tundra. The dragon raised him and taught him the ways of an ice dragon slayer. His journey could start with him leaving the dragon to explore the world, much like Natsu did in the original Fairy Tail story.
In a 'Fairy Tail Lucy becomes a Dragon Slayer' fanfic, it could start with Lucy being in a life - threatening situation. To survive, she unknowingly absorbs the power of a dying dragon. This power starts to change her. At first, she is scared of the changes. But then, with the support of her friends, she decides to embrace it. She then begins a journey to master her new powers. She might learn that her Dragon Slayer magic is linked to a special type of celestial spirit that has dragon - like qualities, and she has to find and bond with this spirit to fully control her powers.
He could also have a strong sense of justice, like most of the Fairy Tail characters. This could be because the ice dragon instilled in him the values of protecting the weak and standing up against evil. He might be a bit stubborn in his beliefs, which could lead to some internal and external conflicts.
Well, there's 'Lightning's Destiny'. In this fanfiction, the OC lightning dragon slayer has to face many challenges that test not only their power but also their loyalty to Fairy Tail. The story does a great job of exploring the world of Fairy Tail from the perspective of an original character with lightning - based abilities. Also, 'Thunderous Beginnings' is quite good. It starts off with the OC's discovery of their dragon slayer powers and how they come to terms with it while interacting with the Fairy Tail guild members.
