It could. Sometimes season 3 makes changes that don't match the initial story.
Yes, it's quite common. Fanfic often takes creative liberties and may go in different directions from the original.
Well, in the original Naruto story, Naruto is mostly seen as a hero or an underdog trying to prove himself. But in this fanfiction, he is feared. This is a huge deviation. The original Naruto is all about friendship, hard work, and believing in oneself. In the fanfiction, it seems to focus more on the negative perception of Naruto, which changes the whole dynamic of his character relationships.
The original story focuses on positive growth through love and support. However, the fanfiction with the 'abuse' concept might take a darker turn. It could introduce themes of struggle and conflict within the family that are not present in the original. For example, in the original, Gohan looks up to Goku, but here, he might have to overcome fear or anger towards Goku.
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.
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'.
The character dynamics are likely to be very different. In the original, Naruto is seen as an underdog trying to gain recognition. As a monster in the fanfiction, he might be feared or shunned, which is a huge departure from the original story where he gradually earns respect through his hard work and determination.
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.
The original Naruto story doesn't depict Naruto as bipolar. So in this fanfiction, it's a major deviation. His stable and determined character in the original is replaced with a more erratic one.
The fairy tale manga is mostly true to the original story. It might simplify some complex parts or emphasize certain aspects for better visualization, but it doesn't stray far from the essence.
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.
