He'd be extremely powerful. Naruto already has a lot of chakra and strong ninja skills. Adding dragon slayer magic would give him new ways to attack and defend. For instance, he could use fire dragon slayer magic to enhance his fire - based jutsus.
In fanfiction about Naruto and Demon Slayer with magic, one interesting aspect is the potential for new power - ups. For instance, a character could combine the Sharingan from Naruto with a Demon Slayer's special vision ability and create a super - powered form of sight. Also, the magic could be used to explain some of the more mysterious elements in both series. Maybe the curse marks in Naruto are actually a form of suppressed magic, and in the fanfiction, a character figures out how to fully utilize this magic, taking on a new and powerful form inspired by Demon Slayer's demon - slaying forms.
Magic in this type of fanfiction can be used to bridge the gap between the two universes. It can make the transition of characters from one world to another more believable. For example, if Naruto characters enter the Demon Slayer world, magic could be the reason they can adapt to the new rules and powers there.
In fanfiction, dragon slayer magic might be outlawed to create more interesting plot twists. For example, it could make the protagonist's journey more difficult as they have to find alternative ways to deal with threats. It also adds a sense of danger and mystery. If everyone could use dragon slayer magic freely, the story might become too predictable.
Well, there are some out there. The idea of Naruto using dragon slayer magic is really cool. In these fanfictions, Naruto could potentially gain new powers and face different kinds of challenges. For example, he might use the dragon slayer magic to fight stronger enemies that his normal ninja skills couldn't handle. It's a great concept that allows for a lot of creativity in the fanfiction world.
Well, in fanfiction, the idea of Issei using Dragon Slayer magic can open up a whole new world of possibilities. It could make him even more powerful in battles against various foes. Maybe it gives him an edge in fighting dragons or other powerful magical creatures that he might encounter in the 'High School DxD' universe.
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.
It could be wind - based, considering Naruto's affinity for wind techniques in his own world. He might be able to create powerful gusts of wind that can cut through enemies like a dragon's roar.
The fanfictions often explore new worlds and dimensions. Since Dragon Slayer Magic comes from a different concept, it can open up portals to other realms. In these stories, Naruto may journey to these new places, face different cultures and powers, and have to find ways to either cooperate or compete with the inhabitants there. This expansion of the Naruto universe makes the fanfictions really engaging.
Surely, fanfiction writers are known for their creativity and coming up with unique crossovers. Given the popularity of Naruto and the allure of dragon - slaying concepts, a 'godlike naruto dragon slayer' fanfiction may exist. It might be a story where Naruto has some extraordinary, god - like powers and is involved in slaying dragons, perhaps in a new and exciting fictional setting created by the writer.
