One common theme is self - discovery. The act of getting a haircut often represents a character's journey to find themselves, like in 'Ruby's Haircut Revelation' where Ruby's new haircut is a sign of her growing into a more confident Huntress.
Romance can also be a theme. A character's new haircut might attract the attention of a love interest. Maybe a character gets a haircut that makes them more attractive to their crush, and the fanfic then explores the relationship that develops as a result of this new look.
Another theme is the reaction of others. In these fanfics, the haircut often causes a stir among the other characters. Some might be supportive, while others might be critical. This can create interesting plotlines as the character with the new haircut has to deal with different opinions and navigate their relationships differently.
One common theme is the exploration of Tukson's true nature. Since he was not fully developed in the original RWBY, fanfics often dig deeper into who he really was. Another theme is his relationship with the other characters in the RWBY world, whether it's friendship, rivalry, or something else.
One common theme is family. Since Weiss and Winter are sisters, a lot of fanfics explore their family dynamic, like how they support or misunderstand each other.
A common theme is power struggle. Lucifer, being a powerful figure, often gets into power - related conflicts with the RWBY characters who also possess various forms of power.
One common theme is identity. Since Neo has a rather mysterious past, many fanfics explore who she really is. Another is revenge. Given her actions in the RWBY series, some fanfics have her seeking revenge or others seeking revenge on her.
One common theme is the distortion of the familiar RWBY settings. For example, Beacon Academy, which is usually a place of learning and growth, can be turned into a haunted and dangerous place. Another theme is the corruption of the characters' powers. Their abilities might be twisted in a way that becomes a source of horror rather than strength. And the threat of the unknown, like strange creatures or forces emerging from the uncharted parts of Remnant.
Growth and development is another theme. Fans like to write about how both characters grow, not just as individuals but also in their relationship. They might show Jaune becoming a stronger fighter and leader, inspired by his love for Pyrrha.
One common theme is self - discovery. Jeanne often has to figure out her place in the RWBY world and her own abilities. Another theme is friendship. She forms bonds with the RWBY characters, which is a key aspect in many fics.
One common theme is acceptance. Since the RWBY world has its own set of social norms, the fanfics often deal with how the characters come to accept their lesbian relationships, both within themselves and in the eyes of others. For example, they might face initial doubts or opposition from friends or family within the story, but eventually find a way to be true to themselves.
