Well, Ron Weasley could also be involved. He has a strong character arc throughout the series and adding this kind of unexpected event to his story could be quite a twist. Also, Severus Snape. His connection to the Dark Arts and potions could make it believable that he might be accidentally or intentionally involved in an experiment that leads to mpreg. And of course, Hermione Granger, who is always in the middle of magical mysteries and could be part of an experiment gone wrong.
Harry Potter himself could be a likely candidate. Given his central role in the series, a lot of fanfictions might explore this strange concept happening to him. Another could be Draco Malfoy. The long - standing rivalry and complex relationship between them could add an interesting dynamic if one of them were to experience mpreg through an experiment.
In some fanfictions, characters like Sirius Black or Remus Lupin might be involved. Their relationship and the fact that they are part of the Marauders could lead to a situation where an experiment goes awry and results in mpreg. Also, new characters that are created specifically for these fanfictions could be the ones to experience this. Maybe a young wizard who is a bit of a maverick and likes to experiment with new magic.
Obviously, Harry Potter himself is the central character as he is the one going through the pregnancy. The Weasley family, especially Molly Weasley, would be involved as the Burrow is their home. Ron and Hermione, being Harry's closest friends, are also likely to be part of the story. Ginny Weasley might also play a significant role, considering her relationship with Harry.
Obviously, Harry Potter himself is the central character as it's about him being mpreg during the first task. His friends like Ron and Hermione are also likely to be involved. They would probably be the ones to support Harry, offer advice, or be shocked by the situation.
Well, in some of these fanfictions, a plotline could be about the experimental process that led to the mpreg in the first place. It might involve some dark magic or a misfired spell. And then there's the relationship aspect. How does the partner of the pregnant character react? Do they support or are they scared? It could also show the character trying to hide the pregnancy at first due to fear of judgment from friends and family in Hogwarts.
The rest of the Weasley family would also play important roles. Mrs. Weasley would be very involved, as she is always concerned about her children. She would probably be a bit flustered at first but then would do everything she could to make Bill comfortable and ensure a healthy pregnancy. And the other Weasley siblings might offer their own unique forms of support, whether it's through humor or practical help.
Severus Snape could be a key figure in such fanfictions. Given his complex character and his knowledge of dark magic, he could either be involved in conducting human experiments for some greater good (in his mind) or be trying to prevent others from doing so. Another character might be Draco Malfoy. He could be forced into participating in a human experiment by his family's allegiance to the Dark side, and then have to deal with the consequences.
Harry Potter himself is often involved. Writers might explore what would happen if Harry was a mutant, like having an enhanced ability to resist the Imperius Curse. Hermione could also be a main character in such fanfictions. She might use her intelligence to study the mutant phenomenon and try to find ways to control or utilize it. Ron could be there too, perhaps with a mutant ability related to his family's Weasley magic, like being able to make their old magical items work in a completely new and powerful way.
Obviously, Harry Potter himself is the central character as the one being abused and neglected. The Dursleys are also key characters as they are the ones who abuse and neglect him in the original story. Hermione and Ron might also be involved as they could be the ones to discover Harry's situation and try to help him. Dumbledore could also be a part of it, perhaps as someone who failed to notice or prevent Harry's abuse initially.
Obviously, Harry Potter himself. Hermione would probably be by his side, helping him research about his claim to lordship, using her vast knowledge from the library. Ron might also be there, providing moral support and his unique sense of humor in difficult situations.
Harry Potter himself is obviously a central character as the focus of the so - called 'harem'. Hermione Granger could be one of the likely characters involved. She is Harry's close friend in the original series and her intelligence and magical abilities would make her a strong contender in any relationship - based competition. Ginny Weasley is also a likely character, as she has a romantic relationship with Harry in the official story. Luna Lovegood might be included too, with her unique personality and magical insights.
Snape is a likely candidate. In the original series, his loyalties were always a bit of a mystery at first. In fanfiction, he could be further explored in terms of false betrayals or real ones. Another one could be Draco Malfoy. He was on the verge of becoming a full - blown Death Eater in the original, so in fanfiction, he could either truly betray his Hogwarts classmates or be wrongly accused of betrayal.
