Mainly it's Danny and Sam. Danny, who can transform into Danny Phantom, is the one with the powers to directly combat ghosts. Sam is crucial too. She has a unique sense of style and a rebellious streak which makes her interesting. In a future fanfiction, they could be older and more experienced, but still retaining their core personalities. Their relationship, which could be either a strong friendship or a romantic one, is also a central aspect of the story.
The main characters would obviously be Danny and Sam. Danny, with his ghost - fighting abilities as Danny Phantom, is a key figure. He can fly, become invisible, and has super strength among other powers. Sam, on the other hand, is Danny's strong - willed and intelligent friend. She is often the voice of reason and also has a deep knowledge of the supernatural which helps in their adventures.
Danny and Sam are the main characters. Danny is the half - ghost hero. He has a dual identity, which often causes him internal conflict as he tries to balance his human life and his ghost - fighting duties. Sam is his loyal and brave companion. She is not afraid to stand up to danger and is always there to support Danny, whether it's in battles against ghosts or dealing with personal issues in their lives.
The two main characters are Danny Phantom and Sam. Danny's transformation into an evil version of himself creates a complex dynamic. Sam, with her unique personality and her relationship with Danny, has to step up. She may be the only one who truly understands Danny enough to be able to combat his evil side. And depending on the fanfiction, other characters like Tucker or Jazz might also make appearances and contribute to the story in different ways.
Sam is also quite popular. Her goth - like personality and her strong - willed nature make her an interesting character. In fanfiction, she can be portrayed in different ways, like being even more involved in Danny's ghost - fighting activities.
Well, perhaps in the future, Danny and Sam get married. They have a family and are trying to live a normal life, but their past as ghost hunters keeps coming back. Their kids start to show signs of having special powers or an interest in the supernatural. Sam and Danny then have to teach them about the world of ghosts while also protecting their family from old enemies that resurface.
Well, it could be that there is no traditional antagonist. Sam's betrayal could be the main source of conflict, and she could be seen as the antagonist in Danny's eyes for that time being. But if there has to be another force, it could be the entity that influenced Sam to betray Danny in the first place. For example, a powerful and manipulative ghost that has its own agenda and uses Sam as a pawn.
Vlad could be a great antagonist. He might see the baby versions of Danny and Sam as an opportunity to finally get rid of Danny for good. He could try to use their weakened state to his advantage and steal Danny's powers once and for all.
One idea could be that Danny and Sam have kids in the future and their kids inherit Danny's ghost powers. The story could focus on how they learn to control their powers while also dealing with normal kid stuff like school and making friends. It would be interesting to see how Sam, as a mom, guides them through this.
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.
The main villain could be an older and more powerful version of Vlad. Maybe he has finally perfected his cloning techniques and created an army of half - ghost clones. He could be more devious and have a grand plan to take over both the human and ghost worlds.
In addition to the ghosts, there might be some human characters that are important in the 'phantom city danny phantom fanfiction'. They could be Danny's friends or family members who get involved in the events of the Phantom City. Their reactions to the supernatural world and their interactions with Danny and the ghosts would add an interesting dynamic to the story.
One interesting story could be about Danny and Sam going on a ghost - hunting adventure together. They might discover a new type of ghost that has unique powers and they have to figure out how to defeat it using their combined skills.
