One popular 'Naruto Otsutsuki DxD Fanfic' is 'Naruto: Shinobi of the Underworld'. It combines the elements of the Naruto universe with the unique aspects of High School DxD in an interesting way. The story often has Naruto facing new challenges and using his shinobi skills in a different, more supernatural setting.
The combination of two very different universes. Naruto's ninja world with its jutsus and shinobi culture, and DxD's world of devils, angels and supernatural beings. It creates a whole new set of possibilities for stories.
One idea could be a crossover where Naruto's Otsutsuki powers somehow connect with the supernatural elements in DxD. For example, his ability to absorb and use chakra could be related to the magic in DxD. Maybe he could use his Otsutsuki powers to enhance the abilities of the devils or angels he meets in the DxD world.
One possible plot could be that Naruto discovers he has some hidden Otsutsuki bloodline. This leads to him being ostracized by some in the village who fear his new - found power. He then has to go on a journey to learn about his Otsutsuki heritage, facing challenges along the way and also having to prove that he's still the same Naruto at heart.
One great 'Naruto Kaguya Otsutsuki Fanfic' is 'The Legacy of Kaguya'. It explores her backstory in a very detailed way. It shows how she came to be the powerful being she was in the Naruto series. The author does a great job of creating new scenarios that fit well with the existing Naruto lore.
Naruto Otsutsuki could fit into the High School DxD universe by being a new and powerful entity. His abilities would be a significant addition. For instance, his transformation abilities like the Nine - Tailed Fox form could make him a force to be reckoned with among the devils, angels, and fallen angels in the DxD world.
One of the most popular crossovers might be the combination of the unique ninja abilities from Naruto Otsutsuki's world with the supernatural elements of High School DxD. For example, the Sharingan could be used in interesting ways in the DxD universe filled with devils and angels. Maybe a character with Sharingan could see through the illusions that devils often use in combat. Another popular crossover could be the use of Naruto's chakra system in the High School DxD world. It could create new power - ups or abilities for the characters there.
Naruto and Rias could be an interesting pairing. Naruto's strong sense of justice and his Otsutsuki powers could complement Rias' leadership and devilish powers. They could work together to protect the DxD world from threats while also learning from each other's different ways of life.
Yes, it could be. The Otsutsuki clan has a significant presence in the Naruto series. Their unique powers and mysterious origin make them quite interesting. A fanfic exploring Naruto's relation to them in a new way might attract fans who are eager to see different interpretations of the story and characters.
Momoshiki Otsutsuki is also quite popular. His powerful abilities and his role as a major antagonist in the Boruto series give a lot of material for fanfic writers. They can expand on his backstory, or create alternate scenarios where he has different interactions with the main characters.
