Who could be potential characters in a Bleach master - slave fanfic?

One idea could be that a powerful Soul Reaper takes on a young and inexperienced one as a sort of apprentice in a master - slave relationship. The master could teach the slave about different zanpakuto techniques and the ways of the Soul Society. For example, they could go on missions together where the master protects the slave at first but gradually lets the slave take on more challenges.

Obviously Skye herself is the main character. There could be a love interest who is the father of the baby. Her best friend could also be an important character, providing emotional support and practical help like going to doctor's appointments with her.

Obviously, Ranma and Akane are prime candidates. Their relationship is central to the series, so a pregnancy between them would create a lot of drama and interesting storylines. Shampoo could also be involved in some way. Maybe she's jealous and tries to interfere, or she could be surprisingly helpful. Genma, Ranma's father, would also play a role. He might have some old - fashioned or comical ideas about the situation.

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.

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.

One potential character could be Sasuke. He has always been highly skilled with weapons and his Sharingan would give him an edge in mastering knife techniques. He has the determination and the combat skills to be a great knife master in a fanfiction setting.

A young apprentice who looks up to the champion of the sun. This character could bring in a fresh perspective and also be a source of comic relief at times. They might have their own small but unique power related to the sun, like being able to create little sun - like orbs for illumination.

Lois Lane could be one of the characters. She has a long - standing relationship with Superman in the original lore, so she could be part of the harem. Then there could be other female superheroes like Wonder Woman. Her strength and noble character could make for an interesting dynamic with Superman in a harem setting. Also, Lana Lang from Superman's past could be included.

Obviously, the other Titans like Robin, Starfire, Cyborg, and Raven would be great characters to include. They could be the students in Beastboy's lessons. Maybe the Doom Patrol members could also make an appearance. They were Beastboy's first team, and they could come in to share their wisdom or add some challenges to Beastboy's teaching. And don't forget about the villains. They could be used as examples of what not to do or as obstacles that the Titans need to overcome using what Beastboy has taught them.

Obviously, Calvin himself as the main character. His parents could also play important roles, showing how their relationship with Calvin has evolved as he grew up.
