Since it's a fanfiction, the author might choose to focus on some of the minor characters from the original series and give them a more prominent role in the context of the 'gods' storyline. For example, Neville could be a key figure if he discovers a connection to a god related to plants or nature, and his new - found power and role in the story could be a central part of the fanfiction.
It's hard to say for sure without reading it, but it could be that Harry, Hermione, and Ron still play major roles. They might be interacting with the gods in some way, either seeking their help or being caught in the middle of a conflict involving the gods.
The main character is Harry Potter without a doubt. However, there could be a whole host of other characters. We might see Dumbledore or other Hogwarts professors making an appearance, trying to understand or guide Harry in this new situation. And then there are the god - characters. They could range from powerful and benevolent deities who want Harry to succeed in his new role as champion, to more malevolent ones who see him as a threat or a tool for their own ends. There could also be new characters created specifically for this fanfiction, like other champions from different magical communities who are also vying for the title or recognition from the gods.
Ron Weasley might be among the main characters as well. His loyalty and courage would still be important traits. He could be by Harry's side, facing the new and more powerful enemies or situations that are part of this fanfiction's 'gods amongst men' concept, and his relationship with Harry and Hermione could be further developed in this new context.
It could be Zeus. He is a powerful god and might see Harry as a worthy candidate for training. He could teach Harry about leadership and power control.
Zeus could be one. He is a powerful god in Greek mythology and might be interested in Harry's story. Another could be Odin from Norse mythology, known for his wisdom. And perhaps Isis from Egyptian mythology, as she has powers related to magic and protection.
Obviously, Harry Potter would be the main character. He would be the one with the new role as the master of the Nordic gods. Hermione and Ron could also be involved. Hermione would be very interested in learning about the Nordic magic and gods, and Ron might be there to provide some comic relief and also be a loyal friend in the new adventures.
The four gods in this fanfiction could be created to fit the unique world of Harry Potter. They might be named after something related to the wizarding world, like one could be the God of Magic Wands, another the God of Potions, etc. However, this is just speculation. It really depends on the creativity of the fanfiction writer. They could also be based on the four elements, with each god having control over one element, like fire, water, earth, and air, and these elements play a crucial role in the magic of the Harry Potter universe as described in the fanfiction.
The Chaos Gods themselves could be the main antagonists. Their very nature is to create chaos and disorder, which would be directly opposed to the order and stability that Hogwarts and the wizarding world try to maintain.
It could be the Greek gods. For example, Athena might bless him with wisdom, which would help him in his studies at Hogwarts and in outsmarting his enemies. Zeus could give him the power of lightning, a very powerful offensive ability.
Well, clearly Vionery is one of the main characters. Depending on the story, Harry Potter himself might also be a central figure, as he often is in most Hogwarts - related fanfictions. Hermione Granger could also be involved, using her intelligence to assist Vionery in her adventures or studies at Hogwarts.
In harry potter the marauders fanfiction, the main characters are the Marauders themselves. James Potter, the confident and sometimes arrogant Gryffindor. Sirius Black, the black sheep of his pure - blood family. Remus Lupin, the kind - hearted werewolf. And Peter Pettigrew, who was initially part of their tight - knit group. Their interactions, friendships, and later the events that lead to their fates are central to these fanfictions. They are often depicted in their Hogwarts days, full of youth, adventure, and magic.
