A plot could involve a spell gone wrong in the Inuyasha world that opens a portal to the Disney realm. Kagome, being from a more modern world, recognizes some of the Disney elements. Mickey Mouse could be the first Disney character they meet. He helps them navigate this new world while Inuyasha is trying to find a way back home. Meanwhile, Disney villains might see Inuyasha as a threat and try to get rid of him. But Inuyasha, with his combat skills, manages to fend them off. In the end, they find a way to close the portal and return home, but not before creating some new friendships and memories.
Inuyasha and Ariel would be an interesting pair. Inuyasha is a rough - around - the - edges half - demon, while Ariel is a curious and adventurous mermaid. Ariel could be fascinated by Inuyasha's otherworldly appearance and his sword, and Inuyasha might be intrigued by Ariel's ability to swim and communicate with sea creatures. They could team up to face a threat that endangers both the sea in the Disney world and Inuyasha's forest in his world.
One idea could be that Sephiroth somehow gets transported to the feudal era of Inuyasha. He might initially be seen as a great threat due to his power. But as the story progresses, he could form an unlikely alliance with Inuyasha and his group against a common enemy, like a powerful demon that is even more menacing than any they've faced before.
A crossover with Moana might be interesting too. Moana could take Elsa and Anna on a journey across the ocean in her boat. Elsa could use her ice powers to create paths or structures on the water. They could face challenges like sea monsters and learn from each other's different ways of life.
A popular one is 'The Meeting of Paths'. This fanfiction focuses on a situation where Inuyasha and Sesshomaru meet under different circumstances than in the original series. It has great characterizations, and the way the two interact and gradually change their views of each other is really well - written.
One idea could be that Sakura, with her medical ninjutsu skills, ends up in the Feudal era of Inuyasha. She could help treat the wounds of the villagers who are often attacked by demons. Inuyasha might be initially suspicious of her strange powers but gradually come to respect her as she proves her worth in battles and in healing the injured. For example, when Inuyasha gets seriously injured in a fight against a powerful demon, Sakura's medical skills could be the key to saving him, which would change his view of her.
Power and growth. Both Inuyasha and Bleach have characters with different levels of power. In crossovers, often a character from one series has to adapt and grow in the other's world, facing new challenges that test their power.
Characterization can be tough. Each character from both series has their own distinct personality. The Avengers have their own dynamics, and Inuyasha has his own temperamental nature. When bringing them together, the writer has to ensure that the characters stay true to themselves while also developing new relationships. For instance, Captain America's sense of justice might clash with Inuyasha's more self - centered approach to fighting at first.
One possible plot could be that Inuyasha somehow gets transported to the Twilight world. He might initially be confused by the modern settings and the presence of vampires and werewolves. Bella could mistake him for a new type of supernatural being. And Inuyasha, with his sword and combat skills, could get involved in the ongoing feud between the Cullens and the werewolves in Forks.
One common theme is the clash of different cultures. Naruto's world is more about ninja villages and modern - ish (for a fantasy world) structures, while Inuyasha's is a feudal era world. So when they cross over, there's often exploration of how these different cultures interact.
