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.
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.
One idea could be a character who is turned into a Grimm due to a failed experiment. They then have to struggle with their new form and inner Grimm instincts while still having memories of their human life. Another could be a human turned Grimm as a result of a dark magic spell, and they try to find a way to reverse it while being hunted by other Huntsmen and Grimm alike.
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.
One interesting idea could be a crossover of different timelines within RWBY. For example, characters from the past meet the current ones and have to deal with the differences in their worlds. Another could be a crossover of different teams in unexpected ways, like Team RWBY having to team up with a rival team to face a common enemy that is more powerful than any they've faced before. And sometimes, there are crossovers that involve alternate versions of the characters, where their personalities or abilities are slightly different, which can lead to very unique and engaging storylines.
Riptide is the most notable one. It's Percy's sword which can transform from a pen to a sword. It's a very unique weapon and is crucial for Percy in his battles against monsters. Another one is Annabeth's Yankees cap which gives her the power of invisibility. It's a human - made item that has been enchanted and can be considered a weapon as it helps Annabeth in her sneaky missions.
One idea could be to have Gilgamesh as a powerful ancient being who awakens in the RWBY world. He could initially be seen as a threat but then form an unlikely alliance with the main characters. For example, he might offer his knowledge of ancient magic to help them fight against a new, powerful Grimm.
One idea could be that the Slenderman somehow enters the RWBY universe during a Grimm attack. The characters of RWBY initially mistake him for a new type of Grimm. But as they start to investigate, they realize he has very different and more sinister powers compared to the Grimm.
One interesting idea could be the redistribution of resources in the RWBY universe. For example, Dust, which is a crucial resource, might be shared more equally among the kingdoms. This could lead to a more balanced power structure and less inequality between the rich and the poor. Another aspect could be the role of the Huntsmen and Huntresses. In a communist - inspired RWBY world, they might work more for the collective good rather than for individual glory or profit. They could be more focused on protecting all people equally, regardless of their social status or wealth.
An OC in RWBY fanfiction could be a character who is a master of stealth. They could use their skills to gather intelligence for the teams at Beacon Academy. Their backstory could involve growing up in a family of thieves, but they decided to use their abilities for good. They might have a Semblance that allows them to become invisible for short periods of time, but it has a drawback like draining their Aura quickly. This OC could interact with characters like Blake, who also has some stealth - like abilities, and they could learn from each other.
For RWBY OC fanfiction, you could make an OC who has the power to manipulate time on a small scale. This would be a really cool ability in battles, being able to slow down opponents or speed up oneself. Another idea is to have an OC that is a faunus with a very rare animal trait, like a phoenix - like faunus. Their story could revolve around hiding their true nature because of discrimination. And an OC that is a transfer student from a far - off land with a completely different fighting style compared to the students at Beacon Academy would also make for an exciting story.
