Their relationship could also develop in a more friendly way earlier on. In the original, Anko is a bit aloof towards Naruto at first. But if they are the same age, they could bond over shared experiences like getting scolded by the same teacher or having a difficult time with a particular exam. They might form a study group together and through that, become really good friends.
If they are the same age, there could be a romantic aspect to their relationship that was not present in the original series. They could start to have feelings for each other as they grow up together. For example, Naruto might be attracted to Anko's confidence and Anko could be drawn to Naruto's kind heart. This could lead to a whole different set of storylines compared to the original where their relationship was more of a senior - junior dynamic.
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 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.
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.
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 story, Naruto and Konan have very different paths and limited interaction. But if they were the same age, they might become friends early on. Maybe they would train together and influence each other's fighting styles. For example, Naruto could learn some of Konan's paper - based techniques, and Konan could be inspired by Naruto's never - give - up attitude.
If Naruto and Kushina were the same age, Naruto might develop more of an empathetic side earlier. Since Kushina was known for her strong will and compassion, being around her could make Naruto more in tune with his emotions. He might not be as reckless as he was in the original story because he'd have Kushina to balance him out.
In the original story, Naruto's journey was more about physical strength and determination. But a smart Naruto would focus more on strategic aspects. He might notice Hinata's potential earlier and encourage her in different ways. Their relationship could develop as a partnership of equals in terms of intellect. They could collaborate on improving the village's infrastructure or education system. This would lead to a more mature and thought - out relationship compared to the more impulsive one in the original.
In the fem Percy and Luke relationship, there might be more of an emotional connection based on understanding each other's struggles as demigods. Since Fem Percy may face different challenges being a female in a male - dominated demigod world, Luke could be more empathetic towards her, which would change the nature of their relationship from the start.
In the original series, Naruto and Kiba's interactions are often in the context of missions and training. In a fem Naruto and Kiba fanfiction, fem Naruto's femininity could add a new dimension. Fem Naruto might be more interested in Kiba's relationship with Akamaru on a different level, like wanting to help train Akamaru to be even better. This could lead to Kiba seeing fem Naruto in a new light. Their relationship could also develop differently because fem Naruto could be more likely to express her feelings towards Kiba, whether it's admiration or annoyance, which could speed up the development of their relationship compared to the original series.
In the original series, Naruto and Obito have a complex relationship mainly based on opposing sides. In a fem Naruto and Obito fanfiction, their relationship could start with more empathy. Fem Naruto might be more understanding of Obito's pain from the start. Maybe she would approach him in a different way, not just as an enemy but as someone who can be redeemed. For example, instead of fighting him right away, she could try to talk to him and get to his heart.
In the original, their relationship was mainly one of enmity. But in this fanfiction, as Fireheart is a girl, there could be more of a complex emotional dynamic. Maybe Tigerclaw would initially underestimate her because she's a female, but then be surprised by her strength and intelligence.
