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.
Hermione might interact with Lena Luthor by being initially skeptical of her scientific knowledge. But as they start to work together, Hermione would come to respect Lena's intelligence. For example, if they were trying to solve a problem that combined magic and technology, Hermione's vast magical knowledge and Lena's tech - savvy would complement each other.
Hermione would likely be very interested in Shikaku Nara's strategic thinking. She would pester him with questions about how he plans and analyzes situations, and they could end up having long discussions about the similarities and differences between magic and ninja skills when it comes to problem - solving.
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.
Hermione, as an Animagus (in this fanfiction), might approach the situation more intellectually. She would first study the Wendigo, trying to understand its nature and origin. Maybe she would research in the Hogwarts library to find any spells or potions that could either calm the Wendigo or protect herself and others from it. She could also use her Animagus form to get closer to the Wendigo without being detected easily.
If Doflamingo and the female Harry Potter character were forced to work together, it would be a very tense relationship. Doflamingo would constantly be testing her limits, while she would be on guard against his sudden betrayals. He might use his powers to intimidate her, but she would respond with her own brand of courage and magic, making their interactions full of drama and conflict.
The biggest deviation would be in Harry's character. In the original, he is kind - hearted and values friendship and justice. Raised by Sephiroth, he could be more cold - hearted. Also, the power dynamics would change. Harry might not rely on the same magic sources as in the original but instead on Sephiroth - inspired powers.
Harry Potter would likely be in awe of Hercules' strength at first. He might be a bit cautious too, as Hercules is from a different world of gods and myths. But they would probably quickly become friends as they both have a strong sense of justice. Hermione would be very interested in Hercules' stories about the Greek gods and would constantly ask him questions, trying to learn as much as she could.
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.
The character might interact with the Nundu through magic. For instance, using spells to calm it down when it gets angry. They could also use treats that are special to Nundus, like a particular type of magical meat. If the character is brave enough, they might even try to play with the Nundu like one would with a normal pet, but always being cautious of its powerful and dangerous nature.
The character might use magic to communicate with the Nundu. For example, a spell that allows them to understand the Nundu's growls and hisses as words. They could also use their wand to soothe the Nundu when it's angry or agitated.
