Typically, in a fanfic that combines Naruto and Bleach elements and involves immortality, you would expect to see Naruto Uzumaki. He is a central character in Naruto and his story could take a whole new turn with immortality. Also, Ichigo Kurosaki from Bleach would probably be there. His unique powers and his journey could be greatly affected by the concept of immortality. There might also be other important characters from both series, like Sasuke from Naruto or Rukia from Bleach, who play important roles in the new narrative of the fanfic.
Since it's an 'immortal naruto bleach fanfic', Naruto and Ichigo are very likely to be main characters. Naruto, with his never - give - up attitude, would have to face the challenges of immortality in a different way. Ichigo, on the other hand, with his dual - nature powers, would also experience a new kind of journey. Besides them, characters like Kakashi from Naruto, who has his own set of skills and experiences, could also be important. And from Bleach, Urahara Kisuke, with his mysterious knowledge, might be involved in the story related to the immortals, either helping or hindering the main characters.
It could also be that an original character created for this fanfic is the main focus. This character, being immortal, would have their own backstory and motives that are central to the plot. They might befriend or oppose Naruto and his friends, leading to various adventures and conflicts.
Sasuke can also be a very popular character. His complex personality and powerful jutsu can create interesting storylines in the 'naruto godlike bleach fanfic' world. He might have some sort of power - up or new relationships with Bleach characters. Also, characters like Rukia are popular as well. Her cool and calm demeanor along with her strong Soul Reaper abilities can make for great interactions with Naruto characters.
Ichigo would probably be one of the main characters. He's the protagonist of Bleach, so it makes sense for him to be at the sleepover. Rukia might also be there, as she has a close relationship with Ichigo. And Uryu could be there too, since he's another important character in the series.
Since it's a fanfic, it could potentially feature any of the main characters from the 'Bleach' series. So, Ichigo Kurosaki could be one of the main characters, as he is the protagonist of the original series. Rukia Kuchiki might also be a main character, as she has a significant connection to Ichigo. Additionally, characters like Uryu Ishida, Orihime Inoue, and Chad could also be main characters depending on the focus of the fanfic.
Without reading the fanfic, it's hard to say for sure. But it could feature the main characters from the 'Bleach' series like Ichigo, Rukia, and Uryu. Since they all have their own sense of duty in the original story, they might be the focus in this fanfic as well, perhaps with new aspects of their duties explored.
Naruto himself is also a top pick. His energetic and determined personality can drive the story forward. His ability to befriend almost anyone can lead to some really interesting interactions with the Bleach characters.
Well, in 'immortal naruto bleach fanfic', there could be the concept of altered storylines. Since the characters are immortal, events that were fatal in the original stories no longer are. This could lead to new alliances and rivalries. For example, a character who was once an enemy might now be forced to work with the protagonist because they are both stuck in an eternal existence. And new characters might be introduced who are specifically interested in the immortals for their own motives, like trying to steal their immortality.
Another theme is the exploration of different worlds. The Naruto universe is very different from the Bleach universe. Fanfics often explore how characters react when they are exposed to the new environment, rules and cultures of the other universe. For instance, a Soul Reaper might be shocked by the idea of chakra in the Naruto world and try to understand it.
Ichigo would be a great main character. He's the protagonist in 'Bleach' and his strong sense of justice and powerful combat abilities would make him a key figure in the Hogwarts setting. He could interact with Harry Potter, and they could learn from each other's fighting styles.
A new human character could be introduced, like a military leader who is leading the invasion. He could have his own motives for wanting to take over the Soul Society, such as a thirst for power or a belief that humans should control all realms.
