The main character is Danny Phantom himself. He's at the center of the story as he discovers and wields the secret weapons. Then there's Vlad Masters. He could be a key character in some fanfictions as he might be after the same secret weapons as Danny, either to use them for his own gain or to stop Danny from having them. Danny's parents also play a role, as their ghost - hunting knowledge and equipment could be related to the secret weapons in some way.
Danny is the main protagonist in Danny Phantom Secret Weapons fanfiction. His ghostly powers are often intertwined with the secret weapons. Sam Manson, with her strong - willed and independent nature, is also involved. She might be the one to find a certain secret weapon that Danny didn't know about. Tucker Foley, who is into technology, is another main character. He could be the one to upgrade or modify the secret weapons. And let's not forget Jazz, Danny's sister. She could be a source of support or even an unexpected wielder of a secret weapon in some fanfictions.
Tucker Foley and Sam Manson are also often main characters. They are Danny's best friends in both his human and ghost - fighting life, so they play important roles in many fanfictions. They might be helping Danny deal with the challenges of his dual identity or getting involved in his battles against ghosts.
Danny is the central character as it's his secret that is being revealed. His friends Sam and Tucker are also main characters. Sam is the goth girl who is always by Danny's side, and Tucker is the tech - savvy friend. If the story involves Danny's love life, then any potential love interests could also be main characters. And we can't forget about Danny's ghostly enemies, like Vlad Plasmius. If the secret is revealed during a battle with him, he would be a significant part of the story as well.
In some fanfictions, Danny's family members can be involved as well. His sister Jazz might be there to support him emotionally or to try and stop him from making a dangerous sacrifice. His parents, who are ghost hunters, could also be part of the story. Their relationship with Danny and their views on his actions can add depth to the fanfiction.
There could also be original characters created specifically for the fanfiction. For instance, a ghostly doctor who specializes in the unique circumstances of a half - ghost pregnancy. Or a new human friend who discovers Danny's situation by accident and has to decide whether to keep the secret or not. These characters can add new twists and turns to the story in the fanfiction.
Obviously, Danny Phantom himself is the central character. His two identities, Danny Fenton the human and Danny Phantom the ghost, are at the core of the identity crisis. His friends Sam and Tucker are also often involved. They are usually the ones who are either helping Danny through his crisis or are unknowingly part of the problem, like when they start to suspect something strange about Danny.
In this type of fanfiction, Danny is the main focus as he endures the sensory overload. Sam and Tucker are key characters as they are Danny's support system. But there could also be appearances from some of the ghost villains like Vlad Masters. He might either be trying to use Danny's overload to his advantage or might be an unexpected ally in helping Danny understand and control his condition. And of course, Danny's family members, especially Jazz, could play important roles in the story.
Well, obviously Danny Phantom himself is usually a main character. He's the half - ghost hero, so a lot of the stories revolve around him. His friends like Sam and Tucker are also often involved. Sam is the goth girl who is very loyal to Danny and Tucker is the tech - savvy friend. Danny's sister Jazz might also be in the story, especially if it's a more family - centered stuck - together scenario.
There could be some ghost characters involved too. For instance, Vlad Masters might show up in the fanfiction. He could be either jealous of Danny's new ability with the claws or try to use it to his own advantage. Another character could be Skulker. He might see Danny's claws as a new trophy to hunt for, which would lead to some exciting chase scenes in the fanfiction.
Obviously, Danny is the main character. His friends like Sam and Tucker are also often involved. Sam might be there to offer her unique brand of support and advice, being the edgy and understanding friend she is. Tucker could provide some comic relief while also being a true friend in Danny's time of heartbreak.
Danny himself can be a main character in such fanfiction. His relationship with his mother, Maddie, can be explored from the perspective of maternal instincts. For example, Maddie's instincts kicking in when Danny is in a particularly dangerous situation with his ghostly foes.
