His character can also develop through his interactions with characters from different time periods. Meeting people with different values and beliefs can make him question his own, and this self - reflection can lead to significant changes in his personality. For instance, if he meets a group of peaceful people in the past, he might start to consider a different way of life. He could become more complex, not just the one - dimensional villain we often see in the original story.
One major difference in the portrayal of the reincarnated Fem Sephiroth compared to the original is her approach to power. The original Sephiroth was somewhat power - hungry and used it in a rather brute - force way. The fem Sephiroth could be more nuanced. She might use her power in a more diplomatic way, relying on her charm and intelligence. Additionally, her backstory as a reincarnation could give her a different perspective on life. She may have memories of her past life that haunt her, but also give her the wisdom to make different choices. This all combines to create a character that is quite distinct from the original Sephiroth.
He could be a powerful antagonist. Picture him arriving in the Naruto world with his otherworldly powers. His sword skills and magic would make him a formidable foe for Naruto and his friends. He might be interested in obtaining some of the unique powers in the Naruto universe, like the tailed beasts' chakra.
In the fanfiction, Sephiroth might protect Cloud by providing emotional support. Maybe he uses his knowledge and experiences to guide Cloud through difficult situations, thus protecting Cloud from making bad decisions or falling into despair. This would be a different way of protecting compared to physical protection, but it's equally important in the context of the story.
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.
When writing a sephiroth x oc fanfiction, it's important to create a believable relationship. You can't just make them fall in love instantly. Build up the tension and the connection gradually. Consider the setting of the story as well. If it's in the world of Final Fantasy, make sure to include elements of that world. And always keep in mind the different arcs of Sephiroth's character. This way, your story will be more engaging and true to the essence of the characters.
In a fanfiction, it might be due to a curse. A powerful curse placed on Naruto by an unknown enemy. This curse could be designed to break down his identity and replace it with that of Sephiroth. As the curse takes effect, Naruto would first start to experience strange dreams and visions of Sephiroth's life. Then, his physical abilities would change, becoming more in line with Sephiroth's superhuman strength and speed. His chakra might even transform into something more like Sephiroth's magic power, and his mind would be filled with Sephiroth - like thoughts of power and domination.
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.
Some writers develop characters in sephiroth crossover fanfiction by giving him new relationships. Maybe in a crossover with a post - apocalyptic world, he forms an unlikely alliance with a group of survivors. This new relationship forces him to reevaluate his views and can lead to changes in his personality. He might start to care about others in a way he never did in his original world, which makes for a very interesting character arc.
It could be a comical take in the fanfic as well. Maybe a crazy inventor or a bumbling wizard accidentally casts a spell that merges the two worlds in a strange way, making Sephiroth Naruto's brother. This would lead to hilarious situations like Sephiroth trying to understand Naruto's love for ramen or Naruto being baffled by Sephiroth's long, flowing hair and his rather dark and brooding personality.
