Kagome from Inuyasha could also be an interesting character in this fanfiction. If she meets Naruto, she might be the one to initially try to bring peace between Inuyasha and Naruto. She's smart and has a good heart. And her knowledge of both the modern world and the feudal Japan world in Inuyasha could help Naruto understand the situation better. Also, her spiritual powers could be useful when they face common enemies.
I think Naruto would be really interesting. He has such a positive and determined personality. In the fanfiction, seeing how he reacts to the strange world of Inuyasha, with all its demons and magic, would be great. He would probably try to make friends with everyone and his never - say - die attitude would be a big asset when facing the dangerous demons 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.
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.
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 Inuyasha and Rin meet in a forest. Rin is now a bit older and has been trained in some basic self - defense skills. Inuyasha is initially cautious around her as she reminds him of his past with Kagome. But as they start to talk, they realize they both have a strong connection to Sesshomaru in different ways. They could end up teaming up to find a lost artifact that has some significance to Sesshomaru's past.
It would probably be the Shinigami. Since it's a mysterious and powerful being from another realm, its motives and actions would be really interesting to follow.
One interesting crossover could be where Inuyasha and his gang end up in the Naruto world. They might be mistaken for strange ninjas at first. Inuyasha could get into fights with some of the stronger ninja clans because of his brash nature. Another cool one would be Naruto somehow ending up in Inuyasha's feudal Japan - like world. He would have to adapt to the different fighting styles and the presence of demons.
One interesting plot could be that Naruto and his friends are on a mission and accidentally end up in Inuyasha's feudal Japan through some sort of magic portal. There, they meet Inuyasha and his group. Naruto's ninja skills could be put to the test against the demons Inuyasha usually battles. And perhaps they team up to defeat a powerful common enemy, like a super - strong demon that neither group could handle alone.
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 could be Naruto himself. He's so full of energy and has this unique ninja power. His presence in the Winx Club's world would be really exciting. He could bring a whole new style of fighting and a different sense of humor.
Definitely Naruto and the Little Sisters. Naruto has a soft spot for those in need, and the Little Sisters are in a very vulnerable position. He would probably be very protective of them, and the contrast between his energetic and positive personality and their rather timid and strange existence would be fascinating.
