I'm not sure specifically which Weiss butt fanfictions are good. However, you can start by looking on popular fanfiction platforms like Archive of Our Own. There, you can search for RWBY fanfictions related to Weiss and browse through the ones that seem interesting based on the reviews and ratings.
First, you need to have a good understanding of Weiss's character. Know her personality traits, her backstory, and her relationships in RWBY. Then, come up with an interesting plot that involves the 'butt' aspect in a creative way. Maybe it could be a humorous situation where Weiss gets into an awkward position that involves her butt, or it could be a more serious plot where her butt has some symbolic meaning related to her character growth.
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.
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.
I'm not sure if there is such specific fanfiction readily available. Fanfiction varies greatly, and while there may be a large body of RWBY fanfiction, this particular theme might be quite rare or not exist at all. It also depends on the various fanfiction platforms and their content policies.
