Obviously Inuyasha himself is the central character in this type of fanfiction. Kagome is often involved as well. She might be the one to support Inuyasha through his pregnancy, given their close relationship. Sango could also be present, perhaps helping with practical matters like finding suitable food or shelter for Inuyasha during his pregnancy.
In addition to the main characters, there could be some original characters introduced in the fanfiction. For example, a wise old healer who has knowledge about this strange pregnancy of Inuyasha. There might also be other demons or spirits that are either drawn to or repelled by Inuyasha's pregnant state. These new characters can add more depth and variety to the story, creating new conflicts and relationships within the world of the fanfiction.
Well, obviously Vegeta is the main character. Bulma would likely be very involved as his partner. Goku might also play a role, perhaps being confused at first but then offering his support.
The main characters are obviously Inuyasha and Kagome. Inuyasha is a half - demon with a complex personality. He is strong and often impulsive. Kagome is a modern - day girl who gets transported to the feudal era. She is kind - hearted and brave.
Often, there are characters from Astrid's community or group. If she's part of a team or a clan, her teammates or clan members will be involved. They might have different reactions, some being very protective and others being a bit skeptical about how her pregnancy will affect the group. There could also be an antagonist who might try to use her pregnancy against her in some way, adding conflict to the story.
Obviously, Mal is the central character. But often, her friends or romantic partners can be important characters too. For example, if she has a significant other, they will play a big role in how she copes with the pregnancy.
The other Hogwarts professors like McGonagall and Flitwick might be included. If Snape is getting revenge on students who misbehaved towards him, characters like Draco Malfoy or the Weasley twins could be part of the story. Draco might be involved if he had previously mocked Snape, and the Weasley twins could be targets if they had played pranks on Snape that he now wants to pay back.
Obviously, Harry Potter himself is the central character. His friends like Ron Weasley and Hermione Granger are also often involved. They might try to visit him while he's grounded or come up with plans to get him out of being grounded. Dumbledore could also play a role, either as the one who enforces the grounding in some cases or as the one who might offer some wisdom to Harry during his time of confinement.
There are many fanfictions out there with all kinds of creative and often out - of - the - ordinary concepts. However, this particular idea seems rather unusual and not in line with the traditional characteristics of the Inuyasha series. In the original series, both Koga and Inuyasha are male characters, and pregnancy in a male - male relationship is not a part of the original story's biological framework. But in the world of fanfiction, writers can bend the rules and create unique scenarios, so it's possible that such a fanfiction exists, but it may not be a common or mainstream one.
Another character that could be involved is a healer or a Jedi master. If Mara Jade is having some complications during her pregnancy, a healer would be needed. And a Jedi master could offer guidance, especially if the unborn child is suspected to have some special connection to the Force. This could lead to interesting interactions and plot developments.
There could also be original characters created specifically for the fanfiction. For instance, a ghostly doctor who specializes in the unique circumstances of a half - ghost pregnancy. Or a new human friend who discovers Danny's situation by accident and has to decide whether to keep the secret or not. These characters can add new twists and turns to the story in the fanfiction.
Obviously, Harry Potter himself is the central character as he's the one getting the wish. Hermione and Ron are also commonly involved. They are Harry's best friends, so they would be there to support him or perhaps even influence his wish. Dumbledore also often shows up in these fanfictions. As the wise headmaster, he might guide Harry on how to use his wish wisely or warn him of the consequences.
