Sephiroth, on the other hand, would likely view Inuyasha as an interesting specimen. He might be intrigued by Inuyasha's half - demon nature and his use of the Tessaiga. Sephiroth could initially try to manipulate Inuyasha or test his limits. However, as they face challenges together, they might develop a grudging respect for each other. For example, if they have to fight a powerful foe that requires both of their unique skills, they would start to see the value in working together.
As they interact more, Inuyasha's more hot - headed and impulsive nature might start to rub off on Sephiroth in a way. Sephiroth is used to being in control and cold - blooded, but Inuyasha's passion for protecting his friends and his world could make Sephiroth question some of his own motives. Meanwhile, Inuyasha might start to understand that Sephiroth's power, while dangerous, can also be used for good in certain situations.
Inuyasha would probably be very wary of Sephiroth at first. Inuyasha is used to dealing with demons and his own set of problems in his world. Sephiroth's otherworldly power and cold demeanor would make Inuyasha see him as a potential threat. He might even attack first out of instinct.
Naruto would probably be very curious about Sephiroth. He'd likely try to be friendly at first, asking a lot of questions. Sephiroth, on the other hand, would be more aloof and might see Naruto as a nuisance or a potential threat. But as time goes on, Naruto's determination might start to intrigue Sephiroth.
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.
Kagome, on the other hand, would be more diplomatic. She could act as a mediator between Inuyasha and the wizards. She might be interested in learning about magic, and the Hogwarts students could be curious about her spiritual powers. Hermione would likely bond with Kagome over their love for knowledge.
Naruto's ability to create multiple clones could be really useful in Inuyasha's world. He could send clones to scout for demons or to distract them while Inuyasha attacks. Inuyasha's Tessaiga, which can cut through almost anything, could be used to break through some of the tough defenses that Naruto's enemies might have. For example, if they faced a really strong earth - style jutsu - created barrier, Inuyasha could slice through it.
The characters would interact in some really interesting ways. For instance, Scrat from Ice Age, with his single - minded pursuit of the acorn, might drive Inuyasha crazy. Inuyasha is used to more straightforward battles and goals, and Scrat's antics would seem really strange to him. On the other hand, Kagome might find the Ice Age animals cute and try to protect them. She has a kind heart, and the animals' innocence would appeal to her. Sango would probably be a bit more cautious around the new - comers, but she would also see the potential in using them as allies against demons.
Rick would probably be very dismissive of the 'primitive' magic in the Inuyasha world at first. He might try to explain it all away with science. Inuyasha, being hot - tempered, would likely get angry at Rick's attitude. Morty would be in awe of Inuyasha's sword - fighting skills and would try to be friendly. Kagome would be curious about Rick's technology and might try to convince him to use it for good in the Inuyasha world.
In a fanfiction, Sakura could use her intelligence and medical skills to help Inuyasha when he gets injured. Inuyasha would be impressed by her ability to heal, which is different from Kagome's spiritual powers. They might also argue a lot, as Sakura is used to a more structured ninja world and Inuyasha is a wild half - demon. But through these interactions, they could grow to respect and even like each other.
Ron would probably be more wary and hostile towards Sephiroth at first. He might see Sephiroth as a threat right away, especially if Sephiroth showed any signs of aggression. Ron would rely on his Gryffindor courage to stand up to him, but his insecurities might also surface. However, as the story progresses, he could learn from Sephiroth's power and maybe even develop a grudging respect if Sephiroth had any redeeming qualities.
Well, when the Avengers first encounter Sephiroth, they'd be quite surprised. Tony Stark would crack a joke to ease the tension a bit but still be very aware of the danger. Steve Rogers would stand tall and be the first to step forward, showing no fear. Thor would grip his hammer tightly, ready to defend. Bruce Banner would be worried that if Hulk gets involved, it could be a very chaotic battle. The female Avengers like Black Widow and Scarlet Witch would be sizing up Sephiroth, trying to find any chinks in his armor. They'd all be on high alert and start formulating a plan to either defeat or contain this unexpected and very powerful new arrival.
The Griffin family would likely react in different ways. Lois would probably try to be the peacemaker and make Inuyasha feel welcome. Chris might be in awe of Inuyasha's strength and cool sword. Meg could see Inuyasha as someone who doesn't fit in, just like her, and they could form an unlikely friendship. Meanwhile, Inuyasha would be constantly on guard, not fully understanding the intentions of these strange new people. He might mistake some of their jokes for real threats and react accordingly, which would lead to some very funny situations.
