What are some interesting plot ideas for a Danny Phantom and Harry Potter brothers fanfiction?

Maybe they discover they are brothers through some supernatural or scientific means. At first, they don't get along as they have very different personalities. Danny is more laid - back while Damian is intense. But as they face challenges together, they learn to trust and rely on each other.

One idea could be a crossover where the magical world of Harry Potter intersects with the ghostly realm of Danny Phantom. Maybe Danny gets accidentally transported to Hogwarts and has to navigate the strange new world of magic while also dealing with his own ghost powers. He could form an unlikely friendship with Harry Potter and together they face a new threat that combines elements from both their universes.

One idea could be that Danny discovers a new ghostly power that he uses to take revenge on a group of bullies who have been tormenting his friends. He could use his intangibility in a creative way, like sneaking into their lockers and making their things disappear.

One idea could be Danny Fenton having to deal with a new ghostly enemy that can manipulate time, making his double life as Danny Phantom even more chaotic. Another could be Danny trying to balance his high school life, including exams and relationships, while also facing a ghost invasion that only he as Danny Phantom can stop. Or perhaps a story where Danny Phantom discovers a hidden power within himself that has a connection to his human side, Danny Fenton.

One idea could be a crossover where Danny Phantom and the Robin Brothers team up to fight a common enemy from their respective universes. Maybe a powerful ghost is causing chaos in Gotham and the combined skills of Danny's ghost powers and the Robins' combat and detective abilities are needed to stop it.

One idea could be that Danny gets an illness that affects his ghost powers. For example, he might start losing control over his intangibility or invisibility. This could lead to some really comical or dangerous situations. Another idea is that his friends try to find a cure for his strange ghost - related illness while also keeping it a secret from the town.

Danny would probably be really curious about all the magic in Harry's world. He might ask a million questions and be eager to try out some spells. Harry, on the other hand, would be intrigued by Danny's ghost powers. They'd likely have a lot of fun showing off their abilities to each other.

Well, imagine if there was a device in the Danny Phantom universe that malfunctioned and created a portal to the Harry Potter world. Danny ends up at Hogwarts during the Triwizard Tournament. He gets involved in the tasks because his powers are seen as an advantage. He might team up with Harry and use his intangibility to pass through obstacles in the maze during the third task. At the same time, he could teach Harry some of his skills, like how to quickly phase through walls to avoid danger.

Well, here's a plot. In a strange turn of events, Danny's ghost powers start to interact with alicorn magic in unexpected ways. This causes chaos in both worlds. The alicorn and Danny must work together to figure out how to stop the strange energy fluctuations. They might have to travel to different dimensions within their universes to find a solution. Along the way, they meet other characters from both franchises who either help or hinder their progress.

One idea could be that Danny is experimented on by a new group of ghost hunters who want to find a way to permanently strip him of his powers. They use some high - tech equipment that has unforeseen effects on his ghostly half, causing him to have strange new abilities. Another could be an experiment gone wrong in the Ghost Zone that Danny has to deal with the consequences of, like accidentally creating a new type of ghost. Maybe Danny himself decides to conduct an experiment to see if he can control his transformation better, but it backfires and he gets stuck in his ghost form for a while.
