It's also likely that Naruto becomes a god dragon slayer as a result of a prophecy. The fanfiction could explore how he initially struggles with this new role. He has to deal with the expectations that come with being a 'god' - level dragon slayer. Along the way, he might make new allies, like other dragon slayers or magical creatures who recognize his potential and help him in his journey to master this new power.
He would likely have enhanced strength. Just like how he could already overpower many foes in the Naruto series, as a god dragon slayer, his physical strength could increase exponentially. He might be able to break through the toughest of dragon scales with his bare hands.
One interesting concept could be the unique powers that a character might gain to slay the dragon god. For example, they might combine Naruto's existing ninja techniques with new dragon - slaying abilities. Maybe they could use shadow clones to distract the dragon god while using a special jutsu to attack its weak points.
The dragon god itself could be the main antagonist. Given its power and the threat it poses to the Naruto universe, it would be a natural choice. It could be a being that wants to destroy the ninja world or enslave it for its own purposes.
One idea could be that Naruto discovers a hidden power within himself that is related to God Slayer Magic. This new power could change the way he battles enemies in the Naruto universe. For example, he might be able to use it against powerful foes like Madara or Kaguya, giving him an edge he didn't have before.
Yes, there are likely to be such fanfictions out there. The concept of combining Naruto with the Dragon Slayer elements from Fairy Tail can lead to some really interesting and creative stories. Fanfiction writers often like to cross over different universes to explore new storylines and character developments.
Power and responsibility is a common theme. As Natsu becomes a dragon god slayer, he has more power, but also more duties. Another theme is friendship. His friends in Fairy Tail still support him even as he changes. And there's often the theme of self - improvement, as Natsu has to master his new abilities.
Often, they start off as strangers. The Poison Dragon Slayer might be confused by the Ninja way of life, like the use of hand signs for jutsu. Naruto, being the friendly and curious type, would approach the slayer and try to understand their powers. They gradually build a friendship based on mutual respect for each other's abilities.
A possible fanfiction could involve Naruto's ninja skills combined with the God Slayer magic from its respective series and the magic of Fairy Tail. For example, Naruto could team up with Natsu from Fairy Tail and a God Slayer character to take on a powerful enemy that threatens all three of their worlds. They would each bring their unique abilities to the fight, like Naruto's shadow clones, Natsu's fire magic, and the God Slayer's divine - based powers.
The concept of Naruto as a Dragon Slayer in Fairy Tail is quite fascinating. Naruto's chakra control could be translated into magic control in the Fairy Tail world. His backstory of being an outcast in his own village could parallel with some of the characters in Fairy Tail who also had difficult pasts. He could learn new spells and techniques from the Fairy Tail mages. Also, his presence in the guild would likely stir things up, as he has a very different fighting style compared to the regular Fairy Tail members.
