First, focus on creating a unique OC. Give them a distinct personality, backstory, and set of abilities. For an ice dragon slayer, think about how their magic works in different situations. For example, how they might use it for defense or offense. Also, make sure to incorporate elements from the Fairy Tail universe, like the guild structure and other known characters.
One great Fairy Tail OC Ice Dragon Slayer fanfiction is 'The Frozen Heart of the Ice Dragon Slayer'. It has an amazing plot where the OC battles with her identity as an ice dragon slayer while trying to fit into the Fairy Tail guild. The character development is really well - done.
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.
Well, she could start off being an outcast in Fairy Tail because her ice powers seem so different from the rest. But then she proves her worth by using her ice dragon slayer magic to save the guild from a powerful water - based enemy. The ice would counter the water and she'd become a hero.
Lucy as an Ice Dragon Slayer could have a very different story arc. Her magic could attract the attention of dark guilds who want to use her power for their own evil purposes. She would then have to fight not only to protect herself but also the people she loves in Fairy Tail. Her training to become a stronger ice dragon slayer would involve learning how to control the cold and use it in combat in the most effective ways.
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, a prevalent theme is the struggle against dark forces. The Ice Dragon Slayer is often in the front line fighting evil. This could be a powerful dark wizard or an entire dark guild. Another theme is the search for identity. They might be of unknown origin or have a mysterious past related to their dragon - slaying abilities. And loyalty is a big one too. The Ice Dragon Slayer shows loyalty to their guild, their friends, and their ideals, which is often tested in different situations in the fanfiction.
One great 'Fairy Tail OC Water Dragon Slayer' fanfiction is 'The Water Dragon's Heir'. It has an amazing plot where the OC, a water dragon slayer, discovers her true heritage while on a journey with the Fairy Tail guild. The character development is really well - done, and it stays true to the spirit of Fairy Tail.
One idea could be an OC Dragon Slayer who has the power of a unique dragon, like a crystal dragon. This slayer could use the dragon's power to create crystal-based attacks. Another idea is an OC who was trained by a dragon in a hidden realm and then enters the Fairy Tail world with a different set of values compared to the regular dragon slayers. Maybe they have a more pacifist view at first but gradually learn to fight when necessary.
A good 'Fairy Tail OC Water Dragon Slayer' fanfiction should have a well - thought - out backstory for the OC. For example, how they became a water dragon slayer, whether it was through a dragon or some other means. It also needs to fit into the existing Fairy Tail universe in terms of magic rules and the guild's culture.
