One idea could be Danny making new friends at the Ghoul School. He could learn about different ghostly cultures and powers there. Another idea is a mystery at the school, like something disappearing and Danny has to solve it. And perhaps Danny could teach the ghouls about the human world in return.
Obviously Danny himself is a must - include. Then there's Sam and Tucker who could visit the Ghoul School with Danny. Among the ghouls, Spectra is quite popular as she has a very interesting personality. Also, the headmistress of the school can be a great character to write about as she has authority and can create interesting plot points.
No, it's not a very common genre. Danny Phantom is mainly associated with its original themes of ghost - fighting and high - school - aged superheroics. School shooting fanfiction is a very dark and serious topic, and it doesn't really fit the more light - hearted or action - adventure feel of the typical Danny Phantom story.
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.
In 'Danny Phantom Goes to School' fanfiction, there could be a new character who is also a half - ghost and they become friends or rivals with Danny. They could team up to fight a powerful ghost that has infiltrated the school's science lab. The school setting also allows for some interesting interactions between Danny's human friends and his ghost - hunting side. For example, his friends might accidentally discover his secret identity while they are all involved in a school project.
Well, obviously Danny Phantom himself. He is the central character as the story likely revolves around his experiences at school and the revelations that occur there.

They are always there to support Danny, whether it's helping him keep his secret or getting involved in the ghost - related adventures that often spill over into the school environment.
Obviously Danny himself is very popular. He's the main character and the source of most of the action and drama. His two best friends, Tucker and Sam, are also often featured prominently. They provide support and comic relief in many fanfictions.
Well, in this kind of fanfiction, Danny could be controlled by an ectoplasmic parasite. The parasite latches onto Danny and takes over his actions. His eyes might glow a different color to show he's not in control. His friends would first be confused, then realize something is amiss and start investigating.
Another possibility is that he's facing some emotional turmoil. Danny has a lot on his plate. He has to keep his identity a secret from his friends and family, deal with school, and fight ghosts. All this stress could be causing him to lose his appetite. He might be too worried or preoccupied to even think about food.
One possible story could be that Danny is facing a new and extremely powerful ghost. He needs help from his friends Tucker and Sam. Maybe they need to find a rare artifact to defeat this ghost. They could start by researching in the local library, looking through old ghost lore books. Tucker uses his tech skills to try and track down any leads on the artifact's location, while Sam uses her knowledge of the occult.
