A possible fanfiction idea could be that a young hunter - in - training discovers a family heirloom which is a human weapon. This weapon has been passed down through generations, but its full capabilities are unknown. As the character trains with it, they start to uncover secrets about their family's past and the origin of the weapon. The weapon could have a unique design that is different from the common RWBY weapons, like it could be a combination of a crossbow and a shield that can split into two separate weapons when needed.
Well, a great fanfiction idea could be centered around a human weapon that was once used by a legendary hero in the RWBY world. The weapon gets lost over time, and the main character stumbles upon it. They then have to learn how to use it while also dealing with the fact that there are those who want to take it from them for their own evil purposes. Or perhaps a story about a human weapon that can transform into different forms depending on the situation. It could be a dagger in close - up combat and then transform into a spear for long - range attacks.
Well, for a RWBY new weapon in fanfiction, think about a weapon that has the ability to manipulate the elements. For instance, a staff that can create fire, ice, or lightning at its ends. Or perhaps a pair of gloves that can harden into metal fists for punching and also generate shockwaves. A whip - like weapon that can split into multiple smaller whips for wider area attacks is also a cool concept. These weapons would add new and exciting elements to the RWBY fanfiction battles.
In my opinion, Jaune Arc could be a really good character to feature. He's always trying to prove himself and a new, powerful human weapon could be the key to his growth as a warrior. The weapon could have some sort of self - training or guiding mechanism that helps him become a better fighter. Oscar Pine is another one. Since he's the new host of Ozpin, a human weapon could play a role in his journey. Maybe it's a weapon that can help him better control Ozpin's power or it could be a weapon that was once used by Ozpin in a past life.
There's also a fanfic that delves into the idea of humans being able to control Grimm. In this fanfic, a group of special humans have the power to communicate and direct Grimm. It shows how this new ability changes the power dynamics in the RWBY world and the moral dilemmas that come with it. For example, should they use the Grimm for good or will the power corrupt them?
One idea could be a crossover where Starkiller's powers are introduced into the RWBY universe. Maybe he teams up with Team RWBY to fight a new, powerful Grimm that is immune to normal Huntsman attacks. His lightsaber skills and Force abilities would add a new dynamic to the battles.
Some fanfictions in RWBY Evolution might focus on unique Grimm designs. They could introduce new types of Grimm with special abilities that the main characters have to face. Also, there could be fanfictions that change the setting, like placing the RWBY world in a different time period, say a post - apocalyptic version of Remnant where the Huntsmen and Huntresses have to deal with even more challenges.
One idea could be a crossover where Megatron somehow ends up in the RWBY universe. He might see the potential for power in the Dust and try to take control of it. Another idea is that the RWBY characters have to team up with an Autobot to stop Megatron from causing chaos in their world.
One idea could be a crossover where the characters from RWBY and Blazblue team up to fight a common enemy. Maybe they have to combine their unique abilities like the Dust powers from RWBY and the Ars Magus from Blazblue.
One idea could be Godzilla emerging in the world of RWBY and the Huntsmen and Huntresses having to figure out how to deal with it. Maybe they initially mistake it for a new type of Grimm.
A fanfiction could also explore a world where the Akatsuki and RWBY teams are merged into one super - team. The different fighting styles and abilities would make for really exciting battles. Characters like Itachi with his Sharingan and Blake with her semblance could combine their skills in stealth and combat to outwit their enemies.
You could write a fanfiction where the Battlefield 1 setting is used as a training ground for the RWBY characters. Weiss could learn about different forms of combat strategy from the military leaders in Battlefield 1. Blake might find inspiration for her stealthy tactics from the snipers in the game. And Yang could engage in some intense hand - to - hand combat with the soldiers. It would be a great opportunity for the RWBY characters to grow and develop new skills.
