The most popular characters are likely Danny and Jake for obvious reasons. But some of the villains also get their share of popularity. In Danny Phantom, Vlad Masters, with his complex relationship with Danny and his own set of powers, can be a fascinating character to write about in fanfiction. In Jake Long, the Huntsman, a formidable foe for Jake, can also be a popular choice. Writers often explore their motives and backstories, and how they might interact with the heroes in different situations.
One interesting storyline could be Danny and Jake teaming up to fight a common supernatural enemy that neither could handle alone. For example, a powerful ancient spirit that threatens both the human and ghost worlds in Danny's case, and the magical world in Jake's. Another could be a crossover where they end up in each other's universes and have to adapt to the new rules and powers while trying to find a way back home.
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.
In a 'danny phantom vs justice league' fanfiction, Danny could use his ghost powers to surprise the Justice League members. His intangibility and invisibility might give him an edge at first. Maybe he'd startle Superman by suddenly phasing through a wall. However, the Justice League has a vast array of powers and skills too. Batman could potentially figure out Danny's weaknesses with his detective skills. And Wonder Woman with her combat experience could pose a real threat to Danny in a face - to - face battle.
In many fanfictions, a plot point could be the exploration of the differences in their power sources. Superman's powers come from the sun, while Danny's are related to the Ghost Zone. This can lead to interesting scenarios where they either learn from each other or try to use the other's power source against them. Another common plot point is the reaction of the people around them. How do the citizens, Lois Lane, or Danny's friends react to this encounter between the two powerful beings?
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.
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.
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.
I think there's no clear - cut winner in a 'danny phantom vs justice league' fanfiction. Danny Phantom is a powerful ghost - hero in his own right. He has unique powers that the Justice League may not be familiar with at first. But the Justice League is a team of some of the most powerful heroes in the DC universe. If the story is written in a way that Danny has some sort of ace up his sleeve, like a new power or a powerful ghost artifact, he could potentially defeat the Justice League. On the other hand, if the Justice League is well - prepared and uses their combined skills effectively, they could overpower Danny.
