Obviously, Harry Potter himself would be a main character. He is the central figure in the Harry Potter series. Then, from the Cullen family, Edward Cullen would likely be a main character. He is the most prominent of the Cullens in the Twilight series and his abilities and personality would make for an interesting interaction with Harry.
Probably Harry Potter and Edward Cullen. Since Edward is sort of the main character among the Cullens in a way, and Harry is the central figure in his world. They both have unique abilities and a sense of responsibility, so it makes sense for them to be the first to cross paths and start interacting.
Obviously, the Cullens would be the main characters. Carlisle, as the patriarch, would play a crucial role in raising Bella. Esme would be like a mother figure to her. Edward would also be important, his relationship with Bella evolving from something different than in the original story. And of course, Bella herself is a central character.
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.
In addition to Harry, Hermione, and Ron, there could be some new characters introduced specifically related to the Jagan. Maybe an old wizard or witch who has some knowledge about the Jagan in the past. They could either guide Harry or try to stop him from getting too involved with it. And of course, there may be some villains who sense the power of the Jagan awakening and want to take advantage of it for their evil plans. Dumbledore or other Hogwarts professors might also play important roles as they often help Harry in difficult situations.
Obviously, Harry Potter would be the main character. He would be the central figure around which the story revolves. Hermione and Ron might also be there, following Harry to Russia to support him in his new role as the so - called 'King of Russia'.
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.
