Obviously, Harry Potter and Severus Snape are the main characters. Harry is the one who is forced into this situation, and Snape is the one he has to please. But other characters like Hermione and Ron could also be involved. They might try to help Harry out of this difficult situation or be affected by the consequences of Harry's actions to please Snape.
There could be some original characters introduced in the fanfiction. Maybe a magical creature or a new wizard who has some connection to the situation. For instance, a wizard who has the power to break the spell that forces Harry to please Snape. Or a magical creature that can help Harry understand Snape's past better, which in turn helps him in his task of pleasing Snape.
Dumbledore could also be an important character. He might be aware of what's going on and be trying to guide Harry in a way that he can both please Snape and still stay true to himself. Also, characters from Snape's side like the Slytherin students could play a role. They might be jealous or intrigued by Harry's forced relationship with Snape.
Obviously, Harry Potter and Snape are the main characters. Harry, with his courage and leadership, and Snape, with his complex past and skills. But other characters like Hermione and Ron could also play important roles. They might be the ones who first notice the change in Snape's behavior towards Harry and help Harry deal with this new situation.
Harry Potter is the main focus, of course. But in addition to Hermione and Ron, we might also see characters like Hagrid. Hagrid has a soft spot for Harry and would surely be concerned about his situation. Ginny Weasley could also play a role, perhaps being more nurturing towards baby Harry. And then there are the villains. Voldemort or his Death Eaters might be involved, either trying to take advantage of Harry's weakened state or being thwarted by the efforts of Harry's friends to protect him.
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.
Well, obviously Harry Potter and Severus Snape are the main characters. Harry is the central figure as it's about his first year at Hogwarts, and Snape is taking him under his wing in this fanfiction.
Perhaps in the fanfiction, Harry is magically bound to please Snape in academic tasks. So, he has to study extra hard in Potions class and other subjects Snape is involved in. This might result in a transformation of their relationship, from animosity to a grudging respect as Snape starts to see Harry's efforts.
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.
