Yes, there are some great ones. You can check fanfiction websites like Archive of Our Own. Just search for 'danny phantom big hero 6' and you'll find various stories that combine elements from both. Some might focus on crossovers where the characters meet and have adventures together.
The most common theme is probably the crossover itself. Writers love to bring the characters from Danny Phantom and Big Hero 6 together. This often leads to themes of cooperation as they have to work together. Another theme is the contrast between the two worlds. Danny's spooky, otherworldly Amity Park is very different from the high - tech San Fransokyo. Fanfiction might explore how the characters adapt to these differences. Additionally, themes of family are present in both shows and are sometimes explored in the fanfiction, like how Danny's family situation might be compared or related to Hiro's family - centric story in Big Hero 6.
A fanfiction that I really like is 'Danny's Secret Mission'. In this story, Danny is sent on a top - secret mission in the human world to stop a group of ghosts that are causing chaos without being detected. The author does a great job of creating suspense. Another interesting one is 'The Ghostly Guardian'. Here, Danny takes on the role of a guardian for a small town, and the way he protects the people there is both heartwarming and action - packed.
The popularity of Danny Phantom hero fanfiction lies in the rich source material. Danny is a complex character with dual identities, which gives writers a lot to work with. His powers and his struggles in both the human and ghost worlds are very interesting to explore in fanfiction.
Well, Danny himself is often a central character in these types of fanfiction. He is the one who is transitioning into or being portrayed as an anti - hero. Sam and Tucker are also commonly included. They might be confused by Danny's new actions and try to bring him back to his old heroic ways. There could also be new characters introduced specifically for the fanfiction, like a shadowy figure who tempts Danny to embrace his anti - hero side.
One interesting danny phantom anti - hero fanfiction could be where Danny starts to question the traditional ideas of heroism. Maybe he gets tired of always being the good guy and having to follow all the rules. He might start making his own decisions that are not so 'hero - like' but are more in line with what he believes is right for the situation.
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.
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.
