There are many out there. Some fanfictions might take a darker turn, where Danny as the ghost prince has to face more dangerous threats not only from the ghost world but also from humans who fear his power. These stories often add a lot of depth to his character and the whole Danny Phantom universe.
Well, it combines the unique world of Danny Phantom with the concept of royalty in the ghost realm. Fans love to see how Danny navigates this new status. His relationships with other characters, both old and new, can be explored in really interesting ways. For example, his interactions with his ghostly subjects or how his human friends react to his new title. Also, the fanfiction can explore the politics and power dynamics in the ghost world, which adds a whole new layer of intrigue.
One great fanfiction could be where Danny has to deal with new threats in the Ghost Zone while trying to balance his life as a prince and a human. Maybe he forms an alliance with some unexpected ghosts to protect his throne.
In a sense, it could be thought of as related to the idea of Ghost Rider fanfiction. Danny Phantom is about a boy who becomes a half - ghost and has to navigate a world of ghosts and other strange phenomena. This is somewhat similar to Ghost Rider's journey with his otherworldly powers. But Danny Phantom is an independent creation with its own lore. It has its own backstory for Danny's transformation, his relationships with other characters like his friends and family, and different antagonists. So while there may be some fanfiction - like connections, it stands on its own as a unique story.
Power struggles are a common theme. Since Danny is the Prince of the Ghost Zone, there are always other ghosts who want to take his position. This creates a lot of drama and action in the fanfictions.

I would recommend 'Danny Phantom: The Prince's Quest'. In this fanfiction, Danny's journey as a prince is filled with challenges. He has to deal with power - hungry ghosts who want to overthrow him. The author does a great job of creating suspense throughout the story. There's also 'The Royal Danny Phantom' which is really interesting as it explores Danny's dual identity as a normal teen and a prince in the Ghost Zone.
One great Danny Phantom Ghost King fanfiction is 'The Reign of the Ghost King'. It delves deep into Danny's new role as the Ghost King, exploring how he balances his human life with his ghostly duties. The character development is really well - done in this fic.
One idea could be that Danny, as a half - ghost, has to prove himself to the Ghost King. Maybe there's a tournament in the Ghost Zone where Danny enters to show his worth. This could lead to some epic battles and alliances with other ghosts.
In a lot of fanfictions, Danny himself often becomes the most powerful ghost. As he grows and learns to control his powers better, he can surpass many of the traditional powerful ghosts in the show. For example, in some fics, he gains the ability to absorb other ghosts' powers, making him extremely formidable.
