Well, aside from Harry Potter, the Serpent King would be a key character. There might also be new characters created specifically for this fanfic. For example, a wizard or witch who has some special connection to the Serpent King, either as an ally or an enemy. Hermione and Ron are also likely to be part of the main cast as they are Harry's closest friends. Their presence would add the element of friendship and teamwork as they deal with the threat of the Serpent King in the fanfic.
In the 'Harry Potter Serpent King Fanfic', Harry Potter is bound to be a central figure. He might be the one who has to face the challenges posed by the Serpent King. Besides, Hermione and Ron could also be important characters. They often stand by Harry in the original series and might do the same in this fanfic. And the Serpent King himself is a main character. He could be a complex figure with his own motives and backstory that the fanfic will gradually reveal.
