In some fanfictions, the demon familiar might be in conflict with the Nine - Tails inside Naruto. This creates an interesting dynamic as Naruto has to balance the two powerful forces within him. The demon familiar could also be from a different dimension, bringing with it unique powers and knowledge that Naruto can use to protect the Hidden Leaf Village. For instance, it might know how to create barriers that are impenetrable to even the strongest enemies.
Well, some fanfictions might explore the idea of Naruto using Samehada to fight against new and powerful enemies. For instance, there could be an enemy that is immune to chakra attacks, but Samehada's ability to absorb chakra gives Naruto an edge. Or perhaps Naruto has to master Samehada quickly to save his friends from a dangerous situation.
One interesting plot could be Naruto using his aura to communicate with long - lost spirits in the Hidden Leaf Village. These spirits might hold ancient secrets that can help Naruto become an even stronger ninja. Another idea is that Naruto's aura attracts a powerful and mysterious ally from a far - off land who is drawn to his unique energy.
One interesting plot idea could be Naruto using his newfound telekinesis to secretly protect his friends without them knowing. For example, he could stop a kunai from hitting Sasuke during a fight by using telekinesis, and Sasuke would be left wondering how he dodged it. Another plot could involve Naruto using telekinesis to move large objects during battles, like moving entire buildings to block enemy attacks. It could also be interesting if he used it to play pranks in a more elaborate way, like making things float around in the village to spook people.
In some fanfictions, the divine dividing could change Naruto's chakra nature. For example, it could give him a chakra nature that is completely new and unheard of in the Naruto world. This new chakra nature could have special properties like being able to nullify other types of chakra attacks. Additionally, the divine dividing might come with a spirit or entity that Naruto has to form a bond with in order to fully control its power. This relationship could be a central part of the story, with Naruto learning from the entity and growing as a ninja and a person.
One plot idea could be Naruto using his prosthetic arm as a symbol of his past battles and how he overcame his injury. It could have special abilities like being able to store chakra more efficiently, allowing him to perform new jutsu. Another idea is that the prosthetic arm is a gift from an unexpected ally, which then leads to a whole new set of adventures and relationships as Naruto tries to figure out the true purpose of the arm.
A really interesting plot could be that Naruto, as a demon, is wrongly accused of a series of attacks in the ninja world. He has to prove his innocence while also dealing with the prejudice and fear that his demon form instills in others. He might have to discover a way to temporarily suppress his demon form to gain the trust of those around him.
One idea could be a crossover where Naruto characters end up in the world of Familiar of Zero. For example, Naruto could meet Louise and they team up to face a common enemy. Maybe an evil mage from the Familiar of Zero world is trying to steal chakra, and Naruto uses his skills to protect everyone. Another plot could be about a character from Naruto becoming a familiar in the Familiar of Zero world, which would create a lot of comical and interesting situations as they try to adapt to the new rules and customs.
One idea could be Naruto getting trapped in the demon world and having to form alliances with different demon clans to find his way back. He could learn unique demon jutsus during his time there.
Well, perhaps Demon Naruto has some sort of special connection to Kushina that is related to his demonic powers. For example, her Uzumaki bloodline might be the key to controlling or understanding his demonic side better. And they could go on a journey to discover the secrets of his powers together.
One idea could be that the demon prince has a hidden power that only Naruto can unlock. This power could be related to an ancient prophecy. Another could be that the demon prince is actually a misunderstood being and Naruto is the first to see his true nature. Maybe they team up to fight a common enemy that threatens both the human and demon worlds.
