Main characters would surely include Harry Potter and Voldemort. But also, characters like Bellatrix Lestrange could be important. As a loyal Death Eater, she would have to adjust to Harry being Voldemort's consort. And on the other side, the Weasley family would also be involved. Molly Weasley, for example, would probably be very concerned about Harry and try to 'save' him from this situation. The centaurs or the house - elves could also be part of the story, maybe providing some unique perspective on this unorthodox relationship.
The main characters would be Harry and Voldemort without a doubt. However, we can't forget about Severus Snape. Since he had a complex relationship with both of them in the original series, he could be a crucial character in this fanfiction. He might be torn between his loyalty to Dumbledore's cause and his understanding of the new relationship between Harry and Voldemort. Nagini, Voldemort's snake, could also be a significant character as she was very close to Voldemort.
Obviously, Harry Potter and Voldemort are the main characters. But there could also be other important characters like Hermione and Ron. Hermione might be trying to understand Harry's decision and Ron could be in shock or even feel betrayed at first. Dumbledore, even in spirit form perhaps, could also play a role as he was always a guiding figure for Harry and his presence could still influence Harry's actions in this strange new situation.
The Weasley family in general would be involved. Ginny, for instance, would be heartbroken seeing Harry on Voldemort's side. The family's loyalty to Harry would be put to the test, and they would be among the main characters as they try to either bring Harry back or fight against him if he goes too far with Voldemort.
Obviously, Harry Potter and Voldemort would be the main characters. Since it's about an 'evil Harry Potter', he would be a central figure with a different personality than the canon Harry. He might be cruel, power - hungry and have a disregard for the rules of the wizarding world. Voldemort, on the other hand, would be the rescuer, perhaps seeing Harry as a tool or a kindred spirit in his evil plans.
Harry Potter is central as the possessed. Voldemort is crucial as the possessor. Harry's friends are bound to be main characters. Hermione, with her intelligence, would be constantly observing Harry's strange behavior and coming up with theories. Ron, being Harry's loyal friend, would be by his side and ready to fight for him. Also, characters like Sirius Black, if he's still alive in the fanfiction's timeline, could be involved. He has a close connection to Harry and would surely want to help him get rid of Voldemort's control.
Obviously, Harry Potter and Voldemort are the main characters. Harry, who makes the unexpected choice to join Voldemort. And Voldemort, who welcomes Harry into his ranks, perhaps with an ulterior motive.
Hermione and Ron are also likely to be important characters. They would be there to support Harry, try to figure out what's going on, and probably try to save Harry from this dangerous situation. Hermione with her vast knowledge of magic might be trying to find a way to break the connection between Harry and Voldemort, while Ron would be there with his loyalty and courage to stand by Harry.
Hermione would be one of the main characters. She might be very skeptical at first about Harry's new friendship with Voldemort. She would constantly be on guard and try to figure out Voldemort's true intentions. Another would be Dumbledore. He would likely be watching the situation closely, trying to guide Harry and also be prepared to deal with Voldemort if he reverts to his evil ways.
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.
