Well, in 'law x oc lemon fanfic', one common theme is the power dynamic. Law has a certain power and status, and the OC might be in a position where she (assuming it's a female OC for simplicity) is either influenced by or challenges that power. There's also the theme of the unknown. The OC coming into Law's world, which is full of danger and mystery, can lead to themes of survival and adaptation. And of course, the romantic and more adult - themed aspects might revolve around the attraction between the two characters, how they handle their feelings, and the physical aspects of their relationship, though these should be written tastefully.
Typically, themes might include adventure since Law is often associated with a world of pirates in the One Piece universe. There could also be themes of romance and self - discovery for the OC (original character).
One common theme could be the exploration of their different personalities. Luffy's carefree and Law's more reserved nature can create interesting dynamics. Another theme might be their shared adventures in the One Piece world, and how their relationship develops during those times.
One common theme is redemption. Often, Dickie's character might be on a path to redeem himself through his interactions with the OC. For example, he could be trying to make up for past mistakes in the SVU world.
One common theme is friendship. Often, the OC forms a strong bond with Olivia, whether it's through shared experiences in solving cases or personal hardships. Another theme is the exploration of Olivia's character in new situations that the OC brings. For example, the OC might introduce Olivia to a different social circle or a new way of thinking about a case.
Typically, 'oc lemon fanfic' often involves original characters in romantic or sexual situations. There's usually a focus on the relationships between these characters, whether it's a new budding romance or an already established one. And the 'lemon' aspect implies some level of sexual content or at least strong romantic undertones.
One common theme is friendship. Since there are three OCs, their relationships with each other often form a big part of the story, like in 'The Trio's Friendship' where they rely on each other through thick and thin.
Another theme might be self - discovery. As the characters interact in the fanfiction, they could be learning more about themselves. For paul and oc, this could be related to their individual personalities and how they change or grow through their relationship. For example, paul might discover a more tender side of himself because of oc, and oc might become more confident. It's all about how they evolve as characters within the story.
A common theme is often the exploration of an unorthodox relationship. Since it involves an Original Character (OC), it's about how this new character interacts with Spock, especially in a romantic and sometimes more intimate 'lemon' context.
One common theme could be forbidden love. Since Loki is often portrayed as a complex and somewhat of an outcast character, a relationship with an original character in a 'lemon' context might involve a sense of secrecy or something that goes against the norms. Another theme could be power dynamics, where Loki's power plays a role in the relationship with the OC.
One common theme could be the exploration of Orochimaru's complex character in relation to the original character (OC). It might involve the OC being drawn into Orochimaru's world of dark magic and experiments. Another theme could be a relationship of power imbalance, where Orochimaru's power and influence play a major role in the story with the OC.
As mentioned before, lemon fanfics often have adult - related themes which are not appropriate to discuss in detail. But generally, they might have themes of romantic or sexual relationships between original characters and existing RWBY characters.
