One common theme is possessiveness. Yandere characters in RWBY fanfic often display an extreme need to possess their love interest. Another theme is the distortion of love. Instead of healthy love, it's a warped version where the yandere will do anything to keep their beloved, even if it means harming others. Jealousy is also a big theme. They can't stand anyone getting close to the object of their affection.
Another theme is the dark side of love. These fanfics usually explore how love can turn into something obsessive and dangerous. For example, a yandere Ruby might go to great lengths to keep her loved one close, even if it means using force.
First, understand Weiss's character. Even as a yandere, she should still have some of her core traits like her pride and elegance. Then, create a strong plot. For instance, her yandere tendencies could be triggered by a specific event, like someone trying to harm a person she loves. Use vivid descriptions, especially when it comes to her expressions and actions when her yandere side is showing.
One popular RWBY yandere fanfic is 'Love in the Shadows'. It has an interesting take on the yandere concept within the RWBY universe. The story focuses on a character who develops an obsessive love for one of the main RWBY girls. Another good one could be 'Yandere's Obsession'. It delves deep into the psychological aspects of a yandere character in relation to the RWBY setting.
One popular yandere Team RWBY fanfic is 'Yandere Ruby's Obsession'. It delves into Ruby's yandere tendencies in an interesting way, with a plot that keeps you on the edge of your seat.
There could also be a story where Weiss is a yandere towards a new character in the RWBY universe. This new character is an outsider who Weiss immediately becomes fixated on. She starts leaving little gifts for the new character, but when the new character doesn't show enough interest back, Weiss's yandere side really starts to show as she tries to force the relationship.
One popular yandere RWBY fanfic is 'Obsessive Affection'. It delves deep into the yandere trope within the RWBY universe. The story follows a character who becomes overly possessive and will go to extreme lengths to keep their 'love' interest close. Another is 'Twisted Devotion' which has an interesting take on how a yandere character's actions impact the RWBY team dynamics. There's also 'Fatal Infatuation' that shows a darker side of yandere behavior in the RWBY setting.
Maybe a powerful and mysterious force affects the minds of some RWBY characters, turning them into yanderes for a particular character. This could lead to a lot of drama as they try to keep their yandere tendencies hidden while also vying for the object of their affection. For example, Ruby could be affected and her normally innocent nature takes on a more possessive and obsessive side when it comes to the person she loves.
First, understand the RWBY universe well. Know the characters, their personalities, and the world they live in. For the yandere part, focus on creating a character with an obsessive love. Decide who they will be obsessed with among the RWBY cast. Then, plan out a plot that shows how this yandere character's actions affect the story. For example, they might try to isolate their love interest from the others.
Yang could be a likely candidate. She's strong - willed and passionate. If she fell into a yandere state, she'd be very protective and possessive. Blake is also a possibility. Given her past and her somewhat reserved nature, if she developed yandere tendencies, she might be more subtle about it but equally as intense.
