Yes, there are likely fanfictions out there with such a plot. Fanfiction writers often explore different relationships and scenarios that might not be part of the original canon. They can create unique stories where Rin and Sesshomaru end up getting married, imagining how their relationship could develop over time and what kind of life they would lead together.
One common theme is friendship. Since they are from different 'worlds' (in the context of the fanfiction), their coming together often leads to the development of a unique friendship. For example, they might learn about each other's strengths and weaknesses and support each other.
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.
Well, one possibility is that Inuyasha might be really confused by Hojo. Hojo is so different from the characters Inuyasha is used to in his own world. He could be very suspicious of Hojo at first.
In this fanfiction scenario, Inutaisho could guide Inuyasha in his journey to become a better demon. He might teach Inuyasha about the history of their kind and how to control his powers more effectively. This could lead to Inuyasha having a new - found sense of purpose and growing in strength and character.
It depends on the writer's perspective. If the writer wants to focus on Inuyasha's brute strength and his experience in battles, then Inuyasha would be more dominant. He's used to taking charge in dangerous situations.
The plot might involve Inuyasha being transported to the Naruto universe. At first, he's confused and a bit hostile. However, Naruto, being the friendly and curious guy he is, tries to befriend Inuyasha. They could end up on a mission together to save a village in the Naruto world. Inuyasha would use his demon - slaying skills while Naruto uses his shadow clones to distract the enemy. It would be a story full of action, friendship, and a bit of comedy as they learn to work together despite their differences.
One possible plot could be that Naruto and his team are on a mission in a strange new land and accidentally cross paths with Inuyasha and his group. They initially mistake each other for enemies but then realize they are both fighting against various forms of evil. They could then team up to defeat a powerful demon that neither group could handle alone.
In the fanfiction, when Inuyasha meets his father, there could be a display of power. His father might teach him some new combat skills or give him advice on how to better control his demon side. It could also be an emotional moment, with Inuyasha finally getting the fatherly guidance he never had growing up.
He might be shocked at first. After all, he has probably only heard stories about his father. Then he could be angry, blaming his father for not being around when he was growing up.
