The other main characters could include Scorpius Malfoy. He and Albus could be best friends, as we saw hints of in the original series' end. And Rose Weasley might also play a major role, being the smart and feisty daughter of Ron and Hermione. She could be involved in some sort of academic or magical mystery at Hogwarts.
Definitely the children of the original characters. For example, Albus Severus Potter could be a central figure, facing his own challenges at Hogwarts. He might have to deal with the legacy of his father.
The main characters could be new students at Hogwarts who have no connection to the famous heroes but are affected by the changes in the wizarding world post - war. They could be from different backgrounds, like a Muggle - born who is struggling to fit in or a pure - blood who has a different view on the new order. And then there could be a character who is a descendant of one of the minor characters from the original series, like a distant relative of Luna Lovegood.
Obviously, Harry Potter himself. He would be a central figure as he was the key in the battle against Voldemort. His friends Ron and Hermione would also be important. They've been with him through thick and thin. Neville Longbottom would be another likely main character. His heroics in the final battle would give him a significant role in the post - battle world. Ginny Weasley too, as Harry's girlfriend and a brave witch in her own right.
Lily Luna Potter is also a favorite. She's a bit of an enigma in the original epilogue, so fanfiction gives writers the chance to really flesh out her character. She could be portrayed as a strong - willed and independent witch, with her own set of adventures at Hogwarts. And of course, Teddy Lupin is popular too. He has a unique backstory, being the son of Remus Lupin and Nymphadora Tonks, and his role in the post - Voldemort wizarding world can be explored in many ways.
Neville Longbottom could also play a more prominent role. Neville has his own growth arc in the series, and after Sirius's death, he could bond more with Harry over their shared experiences of loss. They could support each other in their fight against the Dark Arts. And perhaps some of the Death Eaters who were involved in Sirius's death could be main characters from the antagonist side, as Harry tries to track them down and bring them to justice.
Definitely Harry, Ron, and Hermione. They were the central characters during the war and would likely continue to be important in the post - war stories. They would be using their skills and experiences to shape the new wizarding world.
The main characters would surely include Harry Potter. He's the center of the story as he is the one with the Veela aspect. Ginny Weasley could also be a major character. If Harry is a Veela, it would change their relationship dynamics. Additionally, Dumbledore might play a significant role as he would be guiding Harry through this new discovery and helping him understand and control his Veela powers.
In this kind of fanfiction, Neville Longbottom could also emerge as a key character. He has shown great courage and growth throughout the Harry Potter series. When Hera enters the picture, Neville could be the one who has an unexpected connection with her. Maybe his family's long - forgotten magical heritage has some link to the Greek mythology that Hera represents. And then there are the Death Eaters. If the story is set during the darker times in the wizarding world, the Death Eaters might see Hera as a new threat or a potential ally, making them important characters in the fanfiction as well.
Obviously, Harry Potter would be one of the main characters. He's the central figure in the original series. And Ophis, as the other part of the fanfiction's title, would also be a main character. Her unique abilities and personality would play a big role. Hermione and Ron could also be important as they are Harry's closest friends and would be involved in any new adventures that come about due to Ophis's presence.
Harry Potter himself could still be a main character. He has faced many enemies and situations where he has to make tough decisions. In a 'no forgiveness' scenario, he might be more hardened and less likely to give second chances. For example, when dealing with Voldemort's followers, he could be more ruthless.
Definitely characters from both 'Charmed' and 'Harry Potter'. From 'Harry Potter', Harry, Hermione, and Ron are very likely to be main characters as they are the central figures in the original series. In 'Charmed', the Halliwell sisters, Prue, Piper, and Phoebe, would be prime candidates. Their different powers and personalities would create interesting dynamics when interacting with the 'Harry Potter' characters.
