There might be new characters created specifically for this fanfiction. For example, a wizard who has some knowledge about the combination of Flash - like powers and magic and can help Harry train. There could also be some magical creatures that are attracted to Harry's unique powers. And there could be other students at Hogwarts who either become friends or rivals with Harry because of his extraordinary abilities.
Obviously, Harry Potter himself. Then there would be his friends like Ron and Hermione. They would be there to support Harry and also be amazed by his new powers. Dumbledore would surely be in the story as he is an important figure in Harry's life. And of course, the villains like Voldemort and his Death Eaters who would be the antagonists against Harry's newfound abilities.
In addition to the main characters from the Harry Potter series, there could be some characters related to Flash. Maybe there could be a cameo of Flash himself, perhaps in a vision or a memory that helps Harry understand his powers better. There could also be other characters from the Flash's world that have some connection to Harry's heritage as the son of Flash. And don't forget about the Hogwarts professors, they would play a role in teaching Harry how to control his powers while still being a wizard.
