In some fanfictions, the Queen might be a distant relative of Harry Potter through some convoluted family tree. There could have been a wizard or witch in the royal family long ago who had a relationship with the Potter family line. This relation could bring some interesting plot twists, like Harry having certain rights or privileges in the Muggle world because of this connection.
One possible relation is that the Queen is a patron of the wizarding world in the fanfiction. She could be secretly funding Hogwarts or other magical institutions. This would create a connection between her and Harry Potter as he is part of the wizarding world that she is supporting.
Another relation could be that the Queen is under a magical spell or curse, and Harry Potter has to save her. Maybe a dark wizard has targeted the Queen to gain control over both the Muggle and wizarding worlds, and Harry is the only one who can break the spell and restore order. This would create a direct relation between them as Harry is the hero who comes to her rescue.
In some fanfictions, the Queen might be a long - lost relative of a pure - blood wizarding family. This would lead to her being involved in the complex politics of the wizarding world. She could use her position as the Queen to try and bring about change in the wizarding world's old - fashioned pure - blood - supremacy - based society.
One possible storyline could be that Oliver Queen is transported to the wizarding world during a fight in Star City. He stumbles upon baby Harry Potter and realizes the importance of protecting him. He then has to learn about the wizarding world quickly to keep Harry safe from the dark forces. Another storyline could be that the wizarding world somehow contacts Oliver for help in protecting Harry. Oliver brings his skills and knowledge from his own world to the task.
There could be an interesting plot where the queen, aware of Harry's fame and abilities, enlists his help to solve a long - standing mystery in the royal family. This mystery could be related to some ancient curse or a hidden treasure that has magical properties. Harry, along with his friends from Hogwarts, embarks on a journey to uncover the truth and protect the queen's interests. Or perhaps, the wizarding world and the Muggle world, represented by the queen, need to form an alliance due to a new and powerful dark force emerging. Harry is the bridge between the two worlds and has to ensure the cooperation runs smoothly while serving the queen's needs.
Well, it could be that the Queen has a special connection to the wizarding world in this fanfiction. Perhaps she has been secretly informed of Harry's bravery and selflessness all along. And as a symbol of the British monarchy, she knights him to show that the Muggle and wizarding worlds can have a positive relationship. So, she bestows this honor on Harry.
In this fanfiction, Harry Potter would interact with the Queen in a very unique way. Since he is used to the hierarchical system in Hogwarts, he would understand the importance of showing deference to the Queen. He could offer her a magical gift, like a charm that gives good luck. And the Queen, being curious, might ask him about his world. Harry would have to be careful not to reveal too much about the wizarding world to the muggles, but still satisfy her curiosity. There could be some misunderstandings too, for example, when Harry tries to explain some magic concepts using wizarding terms that the Queen doesn't understand.
Another relation could be through a shared magical artifact. Suppose there's an ancient magical object that has a connection to both of their families. This could bring them together in a quest to understand the power or mystery of the artifact. In the process, they might have to put aside their differences and work together, which would be an interesting exploration in fanfiction.
Well, in a 'fem Harry is a Queen fanfiction', a plotline could be that fem Harry dreams of Queen and in her dreams, the band members give her advice on how to deal with Voldemort. This then gives her the strength and new strategies to fight against the dark forces. Also, it could be that she discovers a hidden connection between Queen's music and ancient magic that only she can unlock, leading to her becoming a more powerful witch.
It could be an original character created specifically for the fanfiction. A young and beautiful queen of a small, yet prosperous kingdom, who has a strong will and a love for her people. She might be open - minded and curious about the wizarding world, which makes her a perfect match for Harry.
It might be an ancient magical being that has the form of a queen. She could have ties to the very origins of magic in the Harry Potter universe and decides to save Harry because she foresees his importance in the future of magic. For example, she could be a guardian of some sort of magic that is crucial for Harry to defeat Voldemort in the long run.
It could be the Queen of England, as in the real - world monarchy. In the fanfiction, she might be a figure with hidden knowledge of the wizarding world and decides to use her power to rescue Harry.
