The orbs in the original Naruto are often tied to specific characters and their abilities. But in fanfiction, we see orbs being used by characters who wouldn't have access to them in the original. They can be combined in ways not seen in the original series, like fusing multiple types of orbs to create a super - orb with a whole new set of powers. This is because fanfiction authors can break the rules of the original story to explore new ideas with the orbs.
In the original Naruto series, orbs might be more straightforward in their use. But in fanfiction, they can be used in crazy ways. For instance, they could be used to time - travel or to create alternate universes. Writers in fanfiction have more freedom to be creative with the orbs.
In fanfiction, the Chunin Vest can be more personalized. While in the original series it mainly represents rank, in fanfictions, it might have custom embroidery or markings added by the character themselves to show their individuality.
In fanfiction, naruto clones can have enhanced abilities. For instance, they might be able to hold chakra for much longer than in the original. This allows them to perform more complex jutsu without disappearing quickly.
In the original series, Naruto mainly copied jutsu through observing and then mimicking the hand signs. In fanfiction, he might copy jutsu just by thinking about it or having a special power - up that allows him to copy jutsu without even seeing the full sequence of hand signs.
His relationships can be changed. In the original, his interactions were somewhat limited. Fanfic authors might give him deeper friendships or romances. For instance, he could have a romantic relationship with a character that was not in his story arc in the original Naruto.
Fuuinjutsu in Naruto fanfic often has different levels of complexity compared to the original. Fanfic writers may introduce new types of seals that have unique properties not seen in the show. For instance, a seal that can transfer a person's soul into another body. Also, the power levels of existing fuuinjutsu might be exaggerated in fanfic to create more intense storylines.
In the original series, Naruto and Hinata's relationship develops slowly over time with Naruto being mostly oblivious to Hinata's feelings. In a vampire Naruto fanfiction, the fact that Naruto is a vampire would add an element of danger and secrecy. Hinata might be initially scared but also intrigued. Their relationship could develop faster as they are thrown into situations where they have to rely on each other more quickly, like when Naruto has to protect Hinata from vampire hunters or other threats related to his new nature.
In the original series, Hedwig is mainly a faithful owl companion. But in fanfiction, she can be much more. She could be a magical entity with her own backstory and motives. For instance, some fanfictions might explore her origin in more detail, like she was bred from a special line of owls with unique abilities.
In the original series, Naruto was more of a regular ninja (with the nine - tails being a part of him but not in a full 'demon' form). In a Demon Naruto x Hinata fanfiction, Naruto's more demonic nature might make him more of an outcast initially. Hinata, being the kind - hearted person she is, would probably be one of the few to reach out to him. Their relationship would develop faster in terms of Hinata being more of a protector and comforter to Naruto's troubled self, compared to the original where Naruto was often the one protecting Hinata.
Well, in the original series, Anko is more of an older, experienced ninja in relation to Naruto. But if they are the same age, their relationship could start as a more equal footing. They might be rivals from the start, constantly trying to outdo each other in training. For instance, they could compete to see who can master a new jutsu faster.
In the original series, Naruto and Ino don't have a very close relationship. But in a Smart Naruto x Ino fanfiction, Naruto's intelligence could make him more aware of Ino's potential as a partner. He might approach her more directly, leading to a quicker development of their relationship. Instead of just being comrades, they could become confidants early on.
