Obviously, Harry would be one of the main characters. He is the one setting the traps for the purebloods. There might also be some pureblood characters who are the targets of his traps. For example, a well - known pureblood family like the Malfoys could be involved, with Draco Malfoy perhaps being a central pureblood character in the story.
It's very likely that Hermione would be involved too. She is Harry's friend and is very intelligent. She could be helping Harry plan and execute the traps, using her vast knowledge of magic. Ron might also be there, providing some comic relief or maybe even some Gryffindor - style courage in the face of the purebloods. And of course, there could be other minor pureblood characters who are caught up in Harry's trapping scheme.
Well, perhaps the plot involves Harry using his knowledge of both the wizarding and Muggle worlds to his advantage. He could be setting traps that incorporate Muggle technology, which the purebloods would be completely unfamiliar with. This would create a situation where the purebloods are constantly on edge, not knowing what to expect from these strange non - magical devices that seem to have a magical effect on them.
Hermione might also be a main character. She's Harry's clever friend and could be helping him plan the escape, using her vast knowledge of magic and spells. She might be the one coming up with the strategies to avoid detection and deal with any obstacles in their way.
Well, clearly Harry and Snap are the main characters. Harry is likely a well - known character, perhaps from the Harry Potter universe. As for Snap, not sure if it's a new character created specifically for this fanfic or a less - known character from the existing lore. Maybe Snap is Harry's friend or a mentor - like figure, and together they are the focus of the story as they flee Britain.
Obviously, Harry Potter would be one of the main characters since it's about him fleeing. Hermione and Ron might also be involved as they are his friends and could either go with him or play a part in his decision to flee.
Hermione Granger often remains popular. In alternate fics, she might be portrayed as an even more powerful witch, leading new magical research or changing the way magic is taught. Harry Potter himself is also a common focus, maybe with different powers or a different role in the wizarding world.
Obviously, Harry Potter is the main character as he is the King of Magical Britain in this fanfiction. His friends like Hermione Granger and Ron Weasley are also likely to be important characters. They would probably be his advisors or help him in his various endeavors.
Ron could also be a major character. He and Harry have a long - standing friendship. Ron might be torn between his loyalty to Harry's new life away from Britain and his own love for his homeland. His perspective could add an interesting layer to the story as he tries to balance both.
Obviously, Harry Potter himself is the central character. He is the one experiencing the exile from Britain. Hermione and Ron might also be important. They could either be trying to help Harry from afar or they themselves could be exiled with Harry, depending on the plot of the fanfiction.
Probably the pilots on both sides, the British ones defending their homeland and the German pilots on the attacking side. Also, there might be some important military commanders who played a role in planning and strategizing during the battle.
Voldemort or his followers could also be relevant in some stories. Maybe Harry is leaving because he fears a resurgence of Voldemort's forces and wants to find a way to defeat them from afar. Or perhaps some of Voldemort's old followers are still after him, and his leaving is a way to draw them away from the innocent people in Britain.
