One important aspect is the setting. Since it's related to Kimimaro Otsutsuki, it should be in line with the Naruto - like world. You can describe the landscapes, the villages, and the different ninja clans. When writing about Kimimaro, stay true to his character. If he is known for his loyalty in the original series, don't make him act out of character in your fanfic. And make your OC bring something new to the story, whether it's a new jutsu or a different perspective on the ninja world.
One interesting plot idea could be Kimimaro Otsutsuki being sent on a secret mission to a far - off planet. He has to face various unknown enemies and strange terrains. Along the way, he discovers a new form of chakra that he has to master in order to complete his mission.
The theme of friendship and isolation is also quite common. She could be isolated because of her connection to Kimimaro or her unique abilities. But at the same time, she might form deep friendships with other characters who see past her differences. These relationships then become a central part of the story, as she learns to trust and rely on others while dealing with her own insecurities.
The development of the OC in a Kaguya Otsutsuki will OC fanfic can be a complex process. Firstly, think about their goals. Are they seeking power, knowledge, or something else? This will drive their actions throughout the story. Their moral compass is also important. If they are faced with Kaguya's often - amoral actions, how will they respond? Will they be swayed or stay true to their beliefs? Moreover, their growth over the course of the fanfic is crucial. They could start as a naive character and gradually become more wise and powerful as they face various challenges and experiences in the Naruto - inspired world.
One great 'female Kimimaro oc fanfic' could be one where the female character is depicted as a powerful ninja in her own right, with unique jutsu skills inspired by Kimimaro's abilities. For example, she might have a bone - like defense mechanism but with a feminine twist, like the bones are laced with a floral pattern.
The plot could involve Kaguya's influence on the OC. Maybe the OC is a new being in the Naruto universe and Kaguya sees potential in them. For example, she could want to use the OC to regain her full power or to create chaos in the shinobi world again. The OC might initially be in awe of Kaguya but then realize her true intentions and have to fight against her.
Power is a common theme. Since the Otsutsuki are a powerful clan in Naruto, OCs often deal with issues of power acquisition, control, and how to use it. For example, an OC might struggle with the newfound power they inherit from their Otsutsuki heritage.
One way is to make the Otsutsuki OC a hidden observer during the Uchiha massacre. They could be there to study the Sharingan or the power dynamics within the Uchiha clan. For example, they might be interested in how the Uchiha's emotions, like hatred, are related to the power of their eyes. Another way is to have the OC be a factor that somehow influences Itachi's decision. Maybe they offer him a different option or some knowledge that makes him rethink his actions, but in the end, the massacre still occurs due to the complex web of political and clan - related reasons in the Naruto universe.
The Otsutsuki OC might be an unexpected bystander during the Uchiha Massacre. For example, they could have been on a different mission in Konoha when the massacre started. They might then decide to get involved, either to save some Uchihas out of a sense of justice or because they see potential in the Uchiha bloodline for their own purposes. So, they end up interfering with Itachi's plan and creating a whole new set of consequences for the story.
Well, there are several. Identity crisis is quite common as the OC is caught between their Otsutsuki heritage and their new life with the Akatsuki. Survival is another big one. The Akatsuki is a dangerous group, and the OC has to find ways to survive among them. And of course, there's the overarching theme of the Naruto universe, which is the pursuit of power and the consequences that come with it. The OC, being related to the Otsutsuki, is often in the middle of this power - hungry world and has to make choices that will affect not only themselves but also the people around them.
