Harry Potter himself is often a popular choice. Given his central role in the original series, fans like to explore different and unique scenarios with him, such as him being the one to experience mpreg. It adds a whole new layer of drama and intrigue to his character.
Hermione Granger could be another character. Since she is a strong and intelligent female character, a fanfiction might explore her role in supporting or being involved in a mpreg situation in the wizarding world. Maybe she uses her vast knowledge to help with the magical aspects of the pregnancy.
Draco Malfoy is also commonly seen in these types of fanfictions. His complex character and his relationship with Harry in the original series can be further explored in the context of mpreg. It could lead to some interesting reconciliations and new relationship dynamics.
Harry Potter himself is often involved. Writers might explore what would happen if he had more control over his powers from the start. Hermione Granger is also popular. She's known for her intelligence and control over her studies, so in fanfiction, she could be given even more control over magical knowledge or spells. Another one is Draco Malfoy. Fanfic writers might give him the ability to control his family's dark legacy and turn it into something positive, or he could be given control over some new form of magic.
Definitely Harry Potter himself can be a part of it. He might be learning to bake as a way to relax or bond with his friends. Luna Lovegood could also be in these fanfictions. She has a very creative and unique personality, so she could bring some really out - of - the - box ideas to the baking table. For example, she might suggest using ingredients that others would find strange but that end up creating a delicious and magical treat.
Draco Malfoy is frequently included as well. His family's dark arts tendencies make him a likely candidate to be involved with hexes, either using them for his own gain or getting caught up in a plot where he has to deal with the consequences of using or being affected by a hex.
Definitely Harry Potter. Fanfiction writers like to dig deeper into his family tree and uncover hidden bloodline secrets. Luna Lovegood can be a character in these fanfictions as well. Her unique personality and family background can add an interesting angle to bloodline exploration. Neville Longbottom is also a likely candidate. Given his family's history and his own growth in the series, exploring his bloodline in fanfiction can open up new storylines, like if there are undiscovered powers or connections in his family's bloodline.
Luna Lovegood is often involved. Her unique and kind - hearted nature makes her a great candidate for an adoptive figure. She could offer Harry a different kind of friendship and family - like bond, one that's filled with her dreamy yet wise perspective on life and magic.
In Pokemon birth fanfiction, Misty can be a popular character. She has a strong connection with water - type Pokemon, and she could be involved in the birth of a water - type Pokemon, perhaps using her knowledge of water to create a suitable environment. Professor Oak is also a character that often shows up. His vast knowledge of Pokemon would make him a valuable asset during a Pokemon birth. And Pikachu, as Ash's most famous Pokemon, might also be part of the story, either as a helper or just being curious about the new - born Pokemon.
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.
Dumbledore is another character often seen in these fanfictions. His great power and wisdom make it believable that he has dabbled in wandless magic. Fanfic writers might explore how he used it in his younger days or how he secretly taught others. Also, Voldemort could be involved, as his pursuit of ultimate power could lead him to explore the boundaries of wandless magic, perhaps seeing it as a way to gain an edge over his enemies.
Draco Malfoy is another character. Some fanfiction could involve body modifications for him, like a charm that changes his appearance to be more like a Veela. This could add a whole new layer of complexity to his character and his relationships with other characters in the story.
Sirius Black is also commonly involved. His relationship with Remus as his friend and his knowledge of Remus' werewolf condition can be delved into deeper. There could be stories about how he helps Remus during difficult times or how their friendship is tested because of Remus' lycanthropy.
