What are some interesting plot ideas for Danny Phantom x Digimon fanfiction?

One idea could be that Skulker, instead of always hunting Danny, teams up with him to face a new and powerful ghost threat that is endangering the entire Ghost Zone. This would force them to put aside their differences and use their unique skills together.

One idea could be that Danny's ghost powers are misinterpreted by Batman as some new kind of meta - human ability. Danny might end up being hunted by Batman at first until they realize they can work together to fight a common enemy like a powerful ghost that has escaped into Gotham.

Maybe there's a rift in the multiverse that connects the two worlds. Integra discovers Danny's powers and tries to recruit him to help in the fight against the vampires. Danny, being a hero in his own world, is hesitant at first but realizes the importance of cooperation when he sees the scale of the vampire threat in the Hellsing universe. He could use his intangibility and flight to outmaneuver the vampires while Alucard and Seras provide the heavy - hitting attacks.

Maybe Pandora has a powerful artifact that could help Danny in his fight against a particularly strong and evil ghost in his own world. Danny travels to Pandora to retrieve it, but he has to face many challenges there. The different ecosystems and magic on Pandora make it difficult for him to navigate, but he also meets some friendly creatures who help him along the way.

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 plot idea could be that Fem Danny Phantom and Vlad have to team up against a new powerful ghost that threatens both their existences. This forces them to put aside their differences and work together, leading to a grudging respect for each other.

One idea could be that Danny has to face Pariah Dark again, but this time Pariah Dark has some new and unexpected powers. Maybe he has found a way to control the Ghost Zone in a different way that poses a huge threat to Danny and the human world. Another plot could be Danny trying to understand Pariah Dark's past to find a weakness. He could discover some ancient secrets about Pariah Dark's origin that no one else knew.

A possible plot is that a villain in the Infinite Stratos world discovers Danny's powers and tries to use them for their own evil purposes. Danny has to team up with the main characters from Infinite Stratos, like Ichika, to stop the villain. Along the way, Danny teaches them about the supernatural and they teach him about mecha piloting.

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.
