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.
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.
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 crossover where a character from RWBY gains the powers of Dishonored's Corvo. They could use the blink ability to quickly dodge attacks in battles against Grimm. Another idea is to have a setting where the world of RWBY is affected by the plague from Dishonored, and the characters have to find a cure while dealing with political unrest.
One idea could be a crossover where The Punisher teams up with RWBY characters to take on a new, powerful criminal organization in Remnant. He could bring his unique combat skills and no - nonsense attitude to the mix.
One idea could be to explore a crossover between RWBY and Darkwatch characters. Maybe Ruby could team up with a Darkwatch hunter to fight a new kind of Grimm that has some vampiric abilities. This would create a really unique dynamic as they combine their different fighting styles and powers.
One idea could be focusing on team strategies for different combat scenarios in RWBY. For example, how Team RWBY might plan to take on a powerful Grimm that has unique abilities. Another could be about the strategic use of Dust in battles, like creating new combinations or ways to deploy it for maximum effect. And a third idea could be exploring the strategic alliances and rivalries between different teams at Beacon Academy.
One idea could be to have Ainz Ooal Gown from Overlord end up in the RWBY world. He could be seen as a powerful new force, and his magic and strategic mind would create a lot of interesting scenarios. Maybe he'd form an alliance with one of the academies, or be seen as a threat by Salem and her forces.
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.
