In some fanfictions, Danny Phantom may hate his parents because they are constantly trying to hunt him down. His parents are ghost hunters and they don't know that Danny is actually half - ghost. So their actions of trying to capture and study ghosts put Danny in a dangerous and uncomfortable position, which could lead to feelings of hatred.
In certain fanfiction, Danny's parents' attitude towards ghosts might be extreme. They view all ghosts as evil and need to be eliminated. But Danny, being half - ghost, has a different perspective. He has friends who are ghosts and he knows that not all ghosts are bad. His parents' narrow - minded view and their attempts to destroy all ghosts, even the good ones, could be a reason for Danny to hate them.
In fanfiction, Danny Phantom could hate Christmas due to personal reasons related to his double life. Maybe he has had bad experiences during past Christmases. For example, he might have been unable to fully enjoy the holiday because he had to deal with a major ghost threat right in the middle of Christmas dinner. Or perhaps he's jealous of how normal people get to celebrate without the added stress of being a half - ghost.
In some fanfiction, the writers might be exploring a darker version of Danny Phantom. His hatred for Amity Park could stem from feeling trapped there. He has all these ghost - fighting responsibilities in Amity Park, and he might just be sick of it. He could be longing for a normal life away from the constant chaos and danger that the town represents to him.
Danny might react with panic at first. After all, he has been hiding his identity from his parents for so long. He could try to escape from them, using his ghost powers in a desperate attempt to get away before they can do anything drastic.
In the fanfiction, the fem Danny Phantom might hate Christmas because it represents a time when she feels most different. If she's a half - ghost, Christmas might be a time when she's acutely aware of not fitting in with either the human or the ghost world. All the normal human traditions and the special 'ghostly' events during Christmas might make her feel isolated. For example, humans are busy with their family dinners and gift - giving, while ghosts might have their own spooky celebrations. She, being in between, has nowhere to belong during this time, thus leading to her hatred for Christmas.
It could be due to a sense of abandonment. Fanfic writers might explore the idea that Harry, growing up without his parents, feels resentful. He may see other kids with their families and, in his confusion and pain, start to hate his parents for leaving him alone in the world, even though it was not their choice.
Well, it could be that Danny is really into the Danny Phantom world and reading fanfiction about it is like a form of 'feeding' his love for the series. Maybe he finds new and exciting ideas in the fanfiction that he can't get from just the original show.
In some fanfictions, Naruto might be depicted as hating his parents. However, this is a departure from the canon. In the original Naruto story, Naruto grows to understand and respect his parents as he learns about their sacrifices. But in fanfiction, authors can take creative liberties and explore different emotional states for Naruto towards his parents, such as hatred perhaps born out of feeling abandoned, even if it goes against the essence of the original story.
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.
Perhaps Danny's friends find out that he has been caught by his parents. They could come to his rescue. Tucker might use his tech - savvy skills to hack into the Fenton's security systems, and Sam could try to reason with Danny's parents. Together, they could try to convince Danny's parents that Danny is still the same person they love, just with some extraordinary powers.
It could be that the revelation brought up some deep-seated issues and caused him to lose trust in others. Maybe he felt betrayed or let down by the circumstances surrounding his parents' identities.
