The main characters would surely include Harry Potter. He is the central figure in the Harry Potter series, and the story is about him being saved. The Winchesters, Sam and Dean, are also key. They bring their own set of skills and personalities from their own show. In addition, characters like Dumbledore might also play a role. He is the wise leader in the wizarding world and could either be aware of the Winchesters' presence or be clueless and later be impressed by their abilities to save Harry.
Harry Potter is a given as the main character in need of saving. The Winchesters, Dean and Sam, are the heroes of the story in this fanfiction. There could also be some antagonists like Voldemort or his Death Eaters. They would be the ones creating the dangerous situations that Harry is in and that the Winchesters have to combat. Other characters from the wizarding world such as Hagrid could also be involved, perhaps helping the Winchesters understand the wizarding world better while they try to save Harry.
The main characters in 'Harry Potter raised by Winchesters' fanfiction would have some interesting interactions. Harry would surely have a lot of interaction with the Winchesters' enemies as well. Demons and other supernatural beings that the Winchesters fight would see Harry as a new target or a strange addition to the mix. In the wizarding world, Harry might interact with Snape in a more confrontational way, as his upbringing by the Winchesters could make him less patient with Snape's attitude. Also, new characters from the cross - over of the two universes could be created, and Harry would be at the center of those interactions.
Well, perhaps the Winchesters, who are known for hunting supernatural beings in their own universe, find a way into the Harry Potter world. Maybe they sense some dark magic that the wizards in Harry Potter's world can't handle on their own. They then use their skills and knowledge of the supernatural to save Harry from a powerful dark wizard or a dangerous magical creature.
Definitely Harry Potter himself. His magic and his sense of right and wrong would bring a new dynamic to the Winchester world. And then there's Dean Winchester. His tough - guy attitude and his skills as a hunter would be really cool to see interact with Harry. Sam Winchester too, with his intelligence and research skills, could be very interesting when combined with Harry's knowledge of the magical 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.
Hermione Granger could also be a rescuer. She was always intelligent and resourceful. In a fanfiction, she might figure out that Harry was in danger at the Dursleys' through some research or a hunch. Then she could use her knowledge of magic to break into the Dursleys' house and get Harry out. She would be brave enough to take on such a task to save her friend.
Most likely, Harry Potter would be one of the main characters as the title implies he is the one being saved. And characters from the Winchester side, perhaps Sam and Dean Winchester. They are the main protagonists in the Winchester universe and would be the ones doing the saving in this fanfiction.
