In a Naruto - Fairy Tail fanfiction with a Water Dragon Slayer, one idea could be that the slayer is from a hidden village that has some connection to Fairy Tail's world. The slayer's abilities would be quite useful in Naruto's world. They could use their water dragon slaying magic to fight against the Akatsuki, for instance. Their magic could be a great asset in battles, especially in areas where there is a lot of water or moisture. It would be cool to see how the Naruto characters react to this new type of power.
One great Naruto Water Dragon Slayer fanfiction could be 'The Water Dragon's Legacy'. It might explore a character with the power of a water dragon slayer in the Naruto universe, dealing with how they interact with the existing ninja clans and their unique abilities. Another could be 'Water Dragon's Ascent', which perhaps focuses on the training and growth of such a character, facing various challenges in the ninja world while harnessing their water dragon slayer powers.
Well, one unique feature is the combination of two different power concepts. Naruto has its own set of ninja abilities and when you add the water dragon slayer power, it creates a whole new dynamic. For example, the way water jutsus can be combined with water dragon slayer attacks is really cool.
The plot might involve the water dragon slayer trying to find a way back to their own world of Fairy Tail while in the Naruto world. Along the way, they learn about the chakra system and how it's different from magic. They could also teach some of the Naruto characters about the power of dragon slayer magic. This could lead to some really interesting training scenes and battles where they combine their different powers. For instance, Naruto could use his shadow clones with the water dragon slayer's water attacks to create a more powerful offensive.
Power and its consequences are also common. The water dragon slayer gains great power, but they also have to deal with the responsibility that comes with it. Sometimes, there are themes of sacrifice, where they have to give up something to save others or achieve their goals.
It could be a new character created specifically for this fanfiction. This character could be a young water dragon slayer who gets lost between the two worlds. They would be the main focus as they try to adapt to the Naruto world while still having their Fairy Tail powers.
The Water Dragon Slayer could fit in by being a foreign visitor. They might come to the Naruto world seeking something, like a special type of chakra that is similar to their magic source. They could then get involved in the local conflicts, using their water - based powers to help or cause trouble depending on their motives.
Often, the main character is an original creation who has the power of a water dragon slayer. For example, in many fanfictions, it could be a young ninja who discovers this power within themselves. They are usually the ones driving the story forward, facing challenges and growing as they learn to control their new abilities.
One common theme is power and growth. As Natsu becomes a water dragon slayer, he has to learn to control his new powers, and the fanfictions often explore how he grows stronger. For example, he might face challenges that force him to adapt quickly.
She could gain water dragon slayer powers after a magical accident. For instance, if she was caught in a magical explosion near a water - based artifact. Her powers could include being able to breathe underwater, which would open up new exploration opportunities for her and the guild. She could discover underwater ruins or hidden treasures.
