Obviously, Harry Potter would be one of the main characters. He is the one doing the baking. And then, the Volturi, as the recipients of his baked goods. They are a powerful group in the vampire world. There might also be some side characters from the Harry Potter universe, like Hermione, who could be helping Harry with the baking or giving him advice on how to deal with the Volturi.
In this fanfiction, Harry Potter might bake for the Volturi as a peace offering. He could be aware of the Volturi's power and influence in the vampire world and wants to establish a connection. The baked items could hold some magical properties that are beneficial to the Volturi, like cakes that enhance their strength or cookies that give them better control over their vampiric abilities.
Obviously, Harry Potter and Marcus Volturi are the main characters. Harry is the well - known wizard from J.K. Rowling's series, and Marcus is an important figure in the Volturi vampire world.
There could also be original characters created specifically for the fanfiction. These characters might be hybrids of wizards and vampires, or they could be ordinary humans caught in the middle of the strange interactions between Harry Potter and Jane Volturi. Their presence could add new storylines and relationships to the overall narrative of the fanfiction.
Mrs. Weasley is a very likely character. She's an expert at cooking and baking in the normal wizarding world, so in fanfiction about magical bakes, she could be teaching the younger characters how to make special bakes. Hagrid might also be involved. He could bring in some really strange ingredients from the Forbidden Forest, like giant acorns, to be used in the bakes.
Obviously, Bella is one of the main characters. And then there are the Volturi leaders like Aro, Caius, and Marcus. They would play important roles as they are the ones in charge and would have a say in whether Bella can truly join them or not. Also, the Cullens might still be part of the story, especially Edward, as his relationship with Bella could be a factor in her decision to join the Volturi.
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.
