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.
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.
I really like 'Weiss and the Faunus Bond'. In this fanfiction, Weiss discovers the unique aspects of Faunus culture through her interactions. It shows her growth as a character as she overcomes her initial prejudices. It also has some great action scenes intertwined with the emotional development.
This fanfiction concept could also explore the relationship between Weiss and Raven. Raven is a complex character, and her training of Weiss could lead to some deep conversations and exchanges of ideas. It could be a way to show Weiss's growth in understanding different perspectives within the RWBY universe.
One great Weiss twin fanfiction is 'The Twin Bond'. It delves into the relationship between Weiss and her twin in a very emotional way. The author does an amazing job of exploring how they interact, their shared past, and how they face challenges together. It also has some really cool fight scenes that are well - written and fit into the RWBY universe.
You can try searching on popular fanfiction websites like Archive of Our Own (AO3). There are often many RWBY - related fanfics there, and by using the keywords 'rwby jealous weiss' in the search bar, you should be able to find relevant stories. Another option is Fanfiction.net, which also has a large collection of RWBY fanfiction.
It's interesting because it takes the normal friendship or team - mate relationship in RWBY and twists it into something much darker and more complex. The yandere aspect adds an element of danger and unpredictability. For instance, Weiss might go to extreme lengths to protect or be with Ruby, which could lead to all sorts of conflicts with other characters. It also explores the idea of love taken to an extreme, which is a concept that can be really thought - provoking.
One idea could be a weapon that combines her ice powers more directly. For example, a staff that can freeze the air around it to create ice shields or projectiles. Another could be a rapier with a hidden mechanism that releases a freezing mist on command, adding an extra layer of defense or offense during combat. Maybe a pair of ice gauntlets that she can use for close - range combat while still being able to cast ice spells from them.
In RWBY male Weiss fanfic, male Weiss often retains the family pride of the Schnee family. He might be just as determined to uphold the family name and restore its honor. For example, he would still face the challenges of breaking free from the family's more negative aspects like their association with certain unsavory business practices.
Naruto's character might develop in terms of his fighting style. Working with Weiss, he could incorporate some of her precision and grace into his ninjutsu. He could also become more attuned to the concept of Dust and how it can be used in combat. Weiss could develop by becoming more adaptable like Naruto. In the Naruto world, she would face different challenges than in RWBY, and having to think on her feet like Naruto does could make her a more well - rounded fighter and person.
