The plot can also be very different. The original story often has her fighting against the forces of evil in a rather traditional superhero - vs - villain setup. However, a breaking fanfic could have her caught in a political intrigue within the Amazonian society itself, rather than an external threat.
Well, it might deviate in terms of the character's personality. In the original, Wonder Woman is known for her strong sense of justice and moral compass. But in a breaking fanfic, she could be more morally ambiguous, making choices that are not as straightforwardly 'good'.
Another way it deviates is in the relationships. In the original, relationships are mainly about friendship, mentorship, and the battle between good and evil. In the diaper fanfic, relationships might be more about caregiving, like who takes care of the diaper - wearing characters, and how they interact in this new, more domestic - like situation.
The obvious deviation is the physical transformation of Naruto into a catgirl. In the original story, Naruto is a male ninja, while in the fanfic, he takes on a more feminine and feline form. This changes his appearance and likely his movement and behavior as well.
Yes, it's quite common. Fanfic often takes creative liberties and may go in different directions from the original.
The relationships in the fanfic are likely to be distinct. Instead of the hero's party dynamics, we'll see new alliances and rivalries among the banished characters. They may team up out of necessity, having a common experience of being cast out, and their interactions will be based on their shared situation rather than the goals of the hero's party.
Well, in the original story, Harry's parents are seen as heroes. But in this fanfic, the whole dynamic is flipped. It's a big deviation as it changes the fundamental view of his parents.
It mainly deviates by changing Celestia's nature. In the original, she is a benevolent ruler, but in the fanfic, she's evil. This changes the power dynamics and relationships in Equestria.
In the original Naruto story, Naruto is all about fairness and honor in fighting. But in 'naruto fights dirty fanfic', he doesn't follow those principles. For instance, he may use poison, which is not his style in the original.
The original Harry Potter story is about good versus evil, with Harry on the side of good. In the 'harry is a murderer fanfic', this fundamental aspect is turned upside down. Harry's actions in the fanfic would likely have a domino effect on other characters and storylines. For instance, his friends in the original story who support him would now be in a completely different position. They might have to oppose him, which is a radical departure from their original relationships.
In the original Naruto story, Kakashi is a mentor and a positive influence on Naruto. He teaches him valuable skills and life lessons. But in the fanfic where he abuses Naruto, it completely goes against that positive relationship.
In the original story, Naruto is an orphan but not stigmatized as a 'bastard child'. So this fanfic clearly changes the social perception of Naruto in the village. In the original, his main struggle is about being alone and getting recognition as a ninja, while here it adds a whole new layer of social discrimination.
