One common theme is the clash and cooperation between magic and Muggle technology. The Royal Navy represents the height of Muggle nautical technology, and when combined with Harry Potter's magic, there are a lot of interesting interactions. For example, using magic to enhance the speed or defenses of the Navy ships.
Another theme is the characters from Harry Potter having new adventures in a naval setting. Harry, Ron, and Hermione often find themselves in situations where they have to adapt to naval life, like following naval protocols while still using their magic secretly. This creates a lot of humorous and exciting scenarios.
One common theme is power. Since Harry is a royal heir, there's often exploration of the power that comes with that status, both in the wizarding world and potentially in the muggle royal world if there are connections. Another theme is identity. Harry has to grapple with this new identity as a royal heir on top of being 'the boy who lived'.
One common theme is power struggle. Since the character is a royal descendant, there are often others who either want to use them or get rid of them to gain power. Another theme is identity discovery. The character usually has to figure out their royal heritage and what it means for them in the wizarding world.
One popular 'Harry Potter Royal Navy fanfiction' might be 'The Marauder's Navy'. It combines the magic of Harry Potter with the nautical world of the Royal Navy in an interesting way.
Another common theme is the struggle against dark forces. In the Harry Potter universe, there's always a threat of dark magic. A Royal Phoenix Animagus might be seen as a symbol of hope or a powerful weapon against the dark. Fanfictions may show the character using their unique abilities to fight against Voldemort or other dark wizards. They might have to overcome their own fears and insecurities to face these powerful enemies, which adds to the character development and the overall tension of the story.
Power and its consequences are also a big theme. The royal elf inheritance usually brings some form of special power, and the fanfictions explore how the characters handle this power. For example, they might face the temptation to use it for selfish reasons or have to learn to control it so as not to cause harm. There are also often political themes related to the power, like how it affects the balance of power in the wizarding world.
Harry Potter himself is of course a common character. Since it's about his royal inheritance, he's at the center of the story. Hermione and Ron are also likely to be involved, as they are Harry's closest friends. They might help him figure out the details of his inheritance or protect him from those who would try to harm him because of it.
It's a bit of a stretch to call it a royal fanfiction. There are some aspects that could be tenuously related to royalty, such as the Weasley family's long - standing place in the wizarding world, but it's not the main focus. The series is mainly about friendship, courage, and the battle between good and evil. The magic, the magical creatures, and the different spells are what really define the series, not any sort of royal - inspired themes.
Obviously, Harry Potter himself is a central character. Then there might be characters like Dumbledore who could play a role in guiding Harry about his royal heritage. Hermione would also be involved, perhaps helping Harry research his family history. Ron could be there for moral support and also be part of the adventures that come with Harry's new - found royal status.
One common theme is adventure. Combining the action - packed world of 007 with the magical adventures of Harry Potter makes for some thrilling stories.
Love and sacrifice are also prevalent themes. We see how the love of Lily Potter saved Harry in the original series, and fanfiction often expands on this idea of love being a powerful force. There are also fanfictions that explore the idea of redemption for characters like Draco Malfoy, showing that even those on the wrong side can have a chance at changing and making amends.
