They would probably have a complex relationship. They might start off not knowing about their relation and then have a big revelation. At first, they could be rivals, given their strong personalities.
One possible plot could be that Naruto discovers he has a long - lost brother who is Inuyasha. They meet in a strange dimension where the worlds of Naruto and Inuyasha collide. Naruto, being his usual self, wants to understand his new - found brother and tries to bond with Inuyasha. Inuyasha, on the other hand, is initially skeptical but gradually warms up to Naruto as they face common enemies together in this new merged world.
It could be a powerful ninja - demon hybrid. This antagonist could be jealous of the bond between Naruto and Inuyasha. He wants to use their combined power for his own evil purposes. So, he tries to turn them against each other first by spreading false rumors and then by attacking their loved ones.
One way this could work in fanfiction is if there was a crossover of universes. Some kind of rift or magical event could have brought their two worlds together. And perhaps they were born from the same source in a new, combined reality. Their relationships with their friends in their respective shows could also be affected. For instance, Sasuke and Kagome might have to deal with this new family dynamic as well.
One way is through crossovers. For example, a character from Naruto could accidentally end up in the world of Inuyasha. They might use their unique ninja skills, like Naruto's shadow clones, to help fight Inuyasha's enemies. This would add an interesting dynamic as the ninja abilities are different from the demon - slaying techniques in Inuyasha's world.
It's really hard to say. Naruto has his incredible chakra powers, his ability to go into different forms like Sage Mode and Nine - Tails Mode. He's also a very skilled ninja with a lot of combat experience. But Inuyasha has his demon strength, his Tessaiga which can cut through almost anything, and his ability to sense demons. In a straight - up fight, it would probably depend on the situation, like the terrain and whether they have any prep time.
The theme of redemption can also be explored. Suppose a villain from Naruto's world ends up in Inuyasha's world. The different environment and the values of the people there might make them question their actions and seek redemption. It's an interesting way to give depth to otherwise one - dimensional characters.
Yes, there might be some. Fanfiction often explores wild and creative concepts like this. Some fans like to blend different universes and character concepts together, so it's possible that there are stories out there where Inuyasha is seen as Naruto reincarnated. However, the quality and popularity of such fanfiction can vary widely.
