What could be an interesting plot in a 'Harry Potter and the Royal Family' fanfiction?

Another plot could involve a member of the royal family in the Muggle world being a Squib. This person, desperate to be part of the magical world, tries to find a way to regain their magic through the help of the Potter family. The story could then revolve around the secrecy that needs to be maintained while also trying to help this person, and how it affects the relationship between the wizarding and Muggle royal families.

One possible plot could be that the Royal Guards in the wizarding world are tasked with protecting Hogwarts during a new threat. They might team up with Harry Potter and his friends. Harry could learn some unique combat or protection spells from them.

One idea could be to focus on the Weasley family. For example, create a story where the younger Weasley siblings start a secret club at Hogwarts to preserve and study the family's magical traditions that are in danger of being forgotten. They could face challenges from other students who think their traditions are old - fashioned.

Obviously, Harry Potter himself would be a main character. And then perhaps Prince William or Prince Harry could be important characters too. They could be the ones who bridge the gap between the Royal Family and the wizarding world. Hermione and Ron might also be involved, helping Harry to deal with the unique situation of the Royal Family in the wizarding world.

The fanfiction might revolve around Harry having an issue with his personal security. The royal family then gets involved. They could offer him enhanced security measures by using their own security teams and protocols. They might also help him in legal matters related to security threats. Additionally, they could work on improving his public image in relation to the security concerns, showing that they are a family that stands together in the face of difficulties.

In a Harry Potter Royal Wedding fanfiction, it could be that the royal family is from a different magical country. The wedding is a political alliance as well as a union of love. Harry Potter is sent as an ambassador from Hogwarts. The wedding preparations could be filled with magical mishaps, like spells going wrong for the decorations. And during the wedding, a long - lost magical artifact is revealed, which has significance for both the royal family and the wizarding world at large. Harry then has to figure out how to handle this new discovery.

One idea could be that the Royal Marines are called in to help Hogwarts during a major attack. They use their military tactics along with magic to fend off the dark forces. Maybe they train the students in some non - magical combat skills too.

One idea could be that the Royal Wizards have a secret society within Hogwarts that Harry discovers. They have ancient spells and knowledge that could help him in his fight against Voldemort.

One idea could be that Mewtwo somehow gets transported to the Harry Potter universe. It could be mistaken for a very powerful magical creature. Harry and his friends could initially be wary of it, but then realize it has no intention of harm and they team up to fight against the dark forces in the wizarding world using Mewtwo's psychic powers.

Another plot could be that Voldemort discovers Powergirl's existence and sees her as a threat. He tries to manipulate the wizarding world against her. But Harry and his friends believe in her and together they work to expose Voldemort's lies and also learn from Powergirl about different ways of fighting evil. Powergirl could introduce new concepts of justice and heroism to the wizarding world.
