A great fanfiction idea could be a time - travel story within the Danny Phantom Phantom Planet universe. Danny somehow gets sent back in time to before he became a half - ghost. He has to figure out how to get back to his own time while also dealing with the knowledge he has of the future. This could lead to some really interesting interactions with his past self, his family, and friends. And he might accidentally change things in the past that could have a huge impact on the future of the Phantom Planet.
One idea could be exploring Danny's new role as a hero on a global scale. Maybe he has to deal with new threats that are attracted to his increased fame. Another could be delving into his relationships with his friends and family after the big events in Phantom Planet. For example, how does his relationship with Sam and Tucker change now that he's a more public hero?
A new character could be a foreign hero who comes to Amity Park to learn from Danny. They might have different powers and a different approach to ghost - fighting. Another possibility is a scientist who is intrigued by Danny's powers and wants to study him, not in a malicious way, but out of pure scientific curiosity.
Sam and Tucker are really interesting characters to focus on. Sam's gothic personality and her strong beliefs can lead to some great storylines. Tucker's tech - savvy nature can be used in many ways, like developing new gadgets or helping Danny figure out some tech - related mysteries. And Jazz, Danny's sister, with her psychology knowledge could play a crucial role in understanding Danny's situation better in a fanfiction.
In this fanfiction, it could be that Danny Phantom meets a Danny Phantom from a parallel fan - made story. At first, they don't trust each other. But as they learn more about each other's worlds, they realize that there are some common elements that are being threatened. It could be that a powerful ghost is trying to rewrite all the fanfic universes related to Danny Phantom. So, they must combine their strengths and knowledge to stop this from happening.
Obviously Danny himself is a must - include. But also Sam and Tucker are great characters to have. They've been with Danny through everything and can add some great human - side to the fanfiction. Valerie could also be included. She has her own complex relationship with Danny and the whole ghost - fighting thing. And of course, there are the ghosts like Vlad. His rivalry with Danny can create a lot of interesting storylines.
Well, a great plot for Danny Phantom Planet fanfiction could be about Danny's life after saving the planet. He might face new challenges like dealing with the fame that comes with being a hero. Some people could idolize him while others might be jealous or even fear him. You could also write about Danny trying to balance his normal life with his superhero duties on a more global scale. He could have to travel around the world to solve problems related to the changes that occurred during the Planet event.
Well, without having read it, it could potentially be about the mother's role in Danny's life as a phantom. It could explore how she supports him, or perhaps how she discovers his double life. It might also involve her having some sort of connection to the phantom realm herself, like she has a special power or knowledge that helps Danny in his battles or in understanding his identity better.
Obviously, the main character would be Danny Phantom himself, but in two different forms or versions. One would be the original Danny Phantom from the canon source, and the other would be a version created by the fanfiction. There might also be his friends like Sam and Tucker who could play important roles in helping the two Dannys understand each other and deal with any issues that arise from their meeting.
He might meet a nurse who has some sort of psychic ability and can sense that Danny is different. This could lead to an interesting interaction where Danny has to be extra careful.
