One interesting idea could be exploring different forms of Danny's transformation. For example, what if his transformation was affected by some new external power? Maybe it could turn him into a more powerful or a completely different looking ghost form.
Danny's relationships with others can also change due to his transformation in fanfiction. If he has a new or different transformation, his friends might react in various ways. Some could be scared, while others might try to help him. This affects how he interacts with them and can lead to character growth. He might become more empathetic towards others' feelings about his powers.
I think Superman would be the most likely. Superman is known for his kind heart and open - mindedness. He would probably see Danny as a young hero in need of some guidance and friendship. He wouldn't be too quick to judge Danny based on his ghostly appearance or powers.
There are also some Danny Phantom fanfiction communities on Tumblr. You can look for tags like '#DannySam' and '#firstkiss'. A lot of Tumblr users create short and sweet fanfiction snippets or reblog existing ones. The advantage of Tumblr is that you can often find really unique interpretations of the Danny and Sam first kiss, with different art styles sometimes accompanying the stories.
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.
In fanfiction, Danny Phantom and Sam's first kiss is often a moment full of anticipation and emotion. It might be described as a culmination of their growing relationship. Writers may use this moment to show the deepening connection between the two characters, perhaps after they've been through a lot together, like fighting ghosts and facing personal challenges.
Well, there's 'Danny's TG Encounter'. In this fanfiction, Danny's TG journey starts when he stumbles upon an ancient ghost artifact. It delves deep into how he copes with the changes in his powers and appearance. Also, 'Ghostly TG Revelations' is quite good. It shows how Danny's TG experiences are linked to the secrets of the ghost world, with some really cool character development along the way.
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.
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.
