A frequent theme is the power dynamic. The yandere Naruto usually has more power, either physical or in terms of influence in the village. The oc has to find ways to deal with this power imbalance. Love and obsession are also big themes. It shows how Naruto's yandere love can be both all - consuming and potentially harmful to the oc. And sometimes there's a theme of redemption, where Naruto may realize the error of his ways and try to change his yandere behavior, but it's often a difficult and complex process.
One common theme is the struggle for the oc against the yandere Naruto's possessiveness. For example, in many stories, the oc is an independent character who values freedom, but Naruto's yandere nature tries to restrict that. Another theme is the exploration of Naruto's character transformation. Normally he is seen as a bright and friendly character, but in these fanfics, his yandere side brings out a darker, more obsessive part of him. There's also often a theme of secrecy and danger, as the oc may be afraid to expose Naruto's true nature to others in the village.
Common themes include the isolation of the oc. Since Naruto is yandere, he may try to isolate the oc from her friends and family in the fanfiction. Another is the internal conflict within the oc. She may have some feelings for Naruto, but at the same time be terrified of his yandere actions. The theme of protection also comes up. Naruto may see his actions as protecting the oc, but in reality, it's more about his own possessive desires. And there's often a sense of mystery as the oc tries to figure out what made Naruto turn into a yandere in the first place.
