A common theme is the struggle between good and evil within Danny himself. Since Dark Danny is Danny's dark side personified, it's all about Danny facing his own inner demons. For example, in many fanfictions, Danny has to deal with the temptation to give in to the power that Dark Danny represents.
One great piece of Danny Phantom vs Dark Danny fanfiction is 'The Battle for Souls'. It really delves into the psychological struggle between the two. The author does an amazing job of showing Danny's inner turmoil as he faces his dark counterpart. It's full of intense action scenes and deep character exploration.
Sam and Tucker are often popular. Sam with her goth style and strong will can add a lot to the story. Tucker with his tech - savvy skills can come up with gadgets that help Danny in the fight against Pariah Dark.
Well, it's appealing because it often delves into themes that the original show might not have fully explored. The idea of Danny succumbing to his darker side and the consequences that follow are really interesting. It also gives fans a chance to see a different side of the familiar characters. There are new relationships to be explored, new powers to be discovered, and new threats to be faced. It's like a whole new world within the Danny Phantom universe but with a darker, more edgy twist.
Danny's relationships change drastically. He distances himself from his friends and family. He no longer values their opinions or support. Instead, he might see them as obstacles or even threats. His friendships with Sam and Tucker are strained as he starts to engage in activities that they find morally wrong, like using excessive force on other ghosts or humans who get in his way.
There's also 'Dark Danny's Reign'. This fanfiction delves deep into what would happen if Dark Danny took over completely. It has some intense action scenes and really shows the power of Dark Danny. It's a great read for those who like exploring the darker aspects of the Danny Phantom universe.
One possible storyline could be that Danny is pushed to the edge by constant bullying at school and the stress of hiding his ghost powers. This leads him to gradually embrace the darker side of his powers and become Dark Danny. For example, Dash's continuous taunts and the school's overall negative attitude towards him make him lose faith in humanity.
One interesting plot point could be Danny's struggle to find a new power or technique to defeat Pariah Dark. Maybe he discovers an ancient artifact that gives him an edge. Another could be the exploration of Pariah Dark's backstory, like how he became so powerful and evil in the first place.
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.
There could be a fanfic where Danny and Ember accidentally swap powers. This leads to a series of comical and also dangerous situations. Danny has to figure out how to control Ember's power of influencing people through music while Ember struggles with Danny's more combat - oriented powers. It could be a story full of self - discovery for both of them.
