Yes, there are likely some fanfictions out there with this concept. Fanfiction writers often come up with unique crossovers, and the idea of Naruto being related to King Gilgamesh in a fan - created story is not unheard of. You can try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net.
He might become more confident, bordering on over - confident like Gilgamesh. Naruto is already confident, but with Gilgamesh as his father, he could have an even greater sense of self - importance.
Well, it depends on what you consider 'good'. There are definitely fanfictions with this concept. I've seen ones where the reincarnation aspect leads to some really interesting power struggles in the Naruto universe. For example, Gilgamesh's pride and arrogance clash with the shinobi values. It makes for some intense character interactions. You should search for tags related to 'Naruto', 'Gilgamesh', and'reincarnation' on the fanfiction platforms to find them.
First, do your research on each of the source materials. Know the power levels, the personalities of the characters in Naruto, Gilgamesh's lore, and the world - building of DxD. Then, come up with a unique concept that can blend these three elements together. For example, you could have a crossover where a Naruto character is transported to the DxD world and meets Gilgamesh there.
It could be Naruto himself. Imagine Naruto with the added powers and characteristics of Gilgamesh. He would be even more of a force to be reckoned with, using his Uzumaki tenacity along with Gilgamesh's haughty confidence and powerful abilities.
Well, it could be that Naruto somehow gets transported to the world of Gilgamesh. Maybe Naruto, with his ninja skills, has to face the challenges in Gilgamesh's world. And Gilgamesh might be intrigued by Naruto's power and determination, leading to an unlikely friendship or rivalry.
I'm not sure exactly as I haven't read that specific fanfiction. It could potentially be about Naruto having god - like powers and being a fan of Gilgamesh in some way, perhaps drawing inspiration from Gilgamesh's characteristics or having some sort of interaction with elements related to Gilgamesh.
Well, one possibility could be that Naruto inherits some of Gilgamesh's arrogance along with his power. Maybe he has a special ability to summon ancient Babylonian weapons. And he could use this in his battles in the Naruto world, like against the Akatsuki.
You can try fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. AO3 has a large collection of various fanfictions, and you can search for 'Naruto x Fem Gilgamesh' in the search bar. FanFiction.net also has a wide range of fan - created stories. Just be sure to read the tags and summaries to find the ones that suit your taste.
One great Naruto, Gilgamesh and DxD fanfiction is 'The Convergence'. It has an interesting plot where the main character from Naruto somehow gets involved in the world of DxD and encounters Gilgamesh. The story is well - written with great character interactions.
