Dumbledore might also be important, even if he's passed away. There could be some final instructions or messages from him that are related to Harry's inheritance. And of course, Ron would be there by Harry's side, providing support and maybe even some comical relief during the whole process of dealing with the inheritance.
Hermione would surely play an important role. She could help Harry figure out the details of his inheritance, like deciphering old documents or researching the history behind it.
Another possible important character could be an old family friend or relative who has been keeping an eye on Harry's inheritance all this time. They could show up and guide Harry through the process, revealing secrets about his family's past and how the inheritance ties into the bigger picture of the wizarding world.
Hermione would definitely be important. She could use her extensive knowledge to help Harry understand his creature inheritance. For example, she might research ancient texts to find out more about the origin of his inherited traits.
Obviously, Harry is the most important character. Then there might be his friends like Hermione and Ron. They could help him understand and manage his inheritance. There may also be some new characters, like an old wizard who is the keeper of the inheritance until Harry is ready. And of course, the antagonists like Draco Malfoy or any remaining Death Eaters might be interested in his inheritance, either to steal it or to stop Harry from using it to gain more power.
Hermione would definitely be an important character. She could use her vast knowledge to help Harry throughout the pregnancy, whether it's with medical advice or just emotional support. Another one could be Dumbledore. He might offer his wisdom and protection, guiding Harry through this unusual situation. And of course, the Weasley family, especially Molly. She could be like a mother figure to Harry during this time, making sure he's eating well and taking care of himself.
Videl would be an important character. Since she has been trying to figure out who Saiyaman is, her reaction when Gohan is revealed would be crucial. Also, Goku. Even though he might not be around all the time, his influence on Gohan and his possible reaction to Gohan's double life as a superhero could be interesting. And of course, Chi - Chi. As Gohan's mother, she would have a lot to say about her son being Saiyaman and how it affects his studies and safety.
Well, perhaps Harry's inheritance includes a hidden library filled with ancient and powerful magic spells. This could lead him to become even more powerful and help him defeat the remaining dark forces. He could also share this knowledge with his friends, making them stronger as well.
Hermione would most likely be involved. She's Harry's best friend and would be eager to help him understand and manage his inheritance. She could use her vast knowledge of magic and research skills to uncover the secrets behind it.
Hermione would definitely be an important character. She's smart and resourceful, so she'd be the one researching ways to restore Harry's memory. Ron would also be crucial as he's Harry's loyal friend. He'd be there to support Harry and keep him out of trouble. Dumbledore or other wise Hogwarts professors like McGonagall could also play significant roles. Dumbledore might have some secret knowledge or plan to help Harry, and McGonagall could provide guidance and protection at Hogwarts.
Neville could play an interesting role. Maybe he could be the one who discovers a new magical plant that is needed for a potion to cure an illness that Ginny or Harry contracts during their marriage. Luna could also be involved. She might come to them with some strange but useful prophecies that help them in a difficult situation, like dealing with a dark wizard who has a grudge against Harry even after the war is over.
His friends are very important. Rukia, for sure. She has a lot of knowledge about the spiritual world and could be the one to figure out what's wrong with Ichigo. Orihime with her healing powers also plays a big role. She might use her abilities to ease his pain or at least keep his condition from getting worse. Uryu could also be important as he might use his Quincy skills to analyze what's causing Ichigo's sickness.
In fanfictions about Harry getting his creature inheritance, he may inherit from a magical creature like a dragon. This could endow him with incredible strength and the ability to breathe fire (in a more magical and less destructive way, perhaps). It could also make him more resistant to heat and fire - spells related to fire might not harm him as much. This new inheritance would likely change his relationships too. His friends might be in awe of his new powers, and his enemies would be more cautious around him.
