In some fanfictions, there could be other supernatural beings involved. For example, vampires who might pose a threat to the baby due to the long - standing feud between werewolves and vampires. Or there could be other werewolves from different packs who have their own opinions on Jacob's situation, which could lead to various sub - plots and conflicts within the story.
Klaus Mikaelson is usually a central figure. His complex character and his role as a father in the fanfiction can lead to many interesting story developments. His relationship with the baby can range from over - protective to conflicted, depending on the plot.
Obviously, Olivia Benson is a main character. She's the one at the center of the story, dealing with the joys and challenges of having a baby. The baby itself is also a key character, though it might not have a fully developed personality yet but still drives a lot of the plot. Sometimes, her colleagues from work might be involved. They could be helping her out or just being there for moral support, like Fin Tutuola or Amanda Rollins.
Obviously, Tonks herself is a main character. She brings her unique Metamorphmagus abilities and her own personality into the Black family dynamic.
Future Mai could also be a key character in Goku Black forced fanfiction. Given her relationship with Trunks and her own skills, she could be part of the group that is fighting against Goku Black, or she might even have some unique interactions with him that drive the plot forward.
Obviously Naruto himself is often involved. He's the main character of the original series, so in fanfiction about Naruto and black holes, he would be at the center of the story. Sasuke might also be involved as his rival and sometimes ally.
One popular story could be about Jacob Black's journey into fatherhood and how he copes with the new responsibilities. It might explore his relationship with the mother and how they navigate raising the baby together.
Obviously, Harry Potter himself is a main character. He is often at the center of the story, trying to understand the significance of the Black Phoenix. Hermione Granger is also commonly included. Her intelligence helps Harry figure out the mysteries surrounding the Black Phoenix, like researching ancient texts about it.
The main characters are Jacob and Bella. Jacob is a werewolf and Bella is a human who has a complex relationship with the vampire world. In the context of this baby fanfiction, they are the parents of the baby, so their actions and decisions will be centered around the well - being of their child.
There could also be side characters like the baby daddy's friends or family members. His best friend might be trying to convince him to either step up or run away from his responsibilities. Or his mother could be a traditional figure who has very specific ideas about how he should handle the situation, adding more conflict to the story.
Sansa Stark might be involved as well. Given her relationship with Jon Snow as his sister (though later revealed otherwise), she could play a role in protecting or being involved with the baby. Maybe she helps raise the baby in a world where Jon Snow is constantly facing threats.
