The plot could revolve around a new character who arrives in Remnant with a Chaos Emerald. This character is being chased by an unknown force from another dimension. The RWBY team decides to help the new character protect the emerald. As they do, they learn about the different abilities of the emerald. For example, it can open portals to other dimensions. They have to fight off the pursuers while also dealing with the temptation of using the emerald's power for their own gain.
One possible plot could be centered around Emerald's self - discovery. Since she has been through a lot in the RWBY series, in the fanfic, she could start to question her loyalty to Cinder after getting chipped. Maybe she meets a group of Huntsmen or Huntresses who show her a different way of life. They help her fix the chip, and in the process, she realizes the true nature of the villains she has been following.
One idea could be a quest to find all the Chaos Emeralds in a post - apocalyptic world where the power of the emeralds is the key to restoring order. Another could be a story where a new character discovers they have a special connection to the Chaos Emerald Z and must learn to control its power to defeat an ancient evil.
One idea could be that the Chaos Emeralds are secretly hidden in Hogwarts. Harry Potter discovers them while exploring the Forbidden Forest. The power of the Chaos Emeralds starts to interact with his magic, giving him new abilities like super speed while flying on his broomstick. He has to keep it a secret from Voldemort who senses the new power source in Hogwarts.
A possible crossover in this fanfiction is in the battle strategies. Naruto's experience in large - scale battles against powerful foes could be shared with the RWBY teams. He could teach them about teamwork in a different way, like how he coordinated with his ninja comrades in Konoha. RWBY characters, on the other hand, could show Naruto how to use the environment and their unique weapons in combat more effectively, which is something different from the ninja tools he's used to.
There might be a fanfiction where Emerald and Mercury are forced to team up with some unlikely allies. This would create a lot of interesting dynamics as they have to adapt to new ways of working and new personalities. Maybe they start to see things from different perspectives and it changes their relationship for the better.
One possible plot could be that a character gets seriously injured during a battle and is rushed to the hospital. While in the hospital, they have to deal with their own fears and insecurities as they recover. Meanwhile, their teammates visit them and there are some heart - to - heart conversations that strengthen their bonds.
In a 'doomguy in rwby fanfiction', Doomguy could be a mysterious figure that the RWBY characters hear rumors about. He's said to be this super - powerful warrior from another realm. Eventually, they cross paths. Doomguy has a hard time adjusting to the more colorful and magical world of RWBY at first. But as he gets used to it, he starts using the resources of this new world, like Dust, to enhance his weapons. His presence also changes the dynamics of the relationships between the RWBY characters as they all learn from his no - nonsense attitude towards fighting.
Another theme is loyalty. Some fanfictions focus on Emerald's loyalty, whether it's her past loyalty to a certain group or her new - found loyalty to different people as she changes. For instance, she could be torn between her old comrades and new friends she makes along the way.
The power - up trope also appears in Emerald fanfictions. Writers might give her new powers or enhance her existing ones, and then explore how she uses these new abilities. It could be related to her facing a greater threat or just her personal growth within the story.
In RWBY Volume 6 fanfiction, Emerald can play various roles. She could be a protagonist in some stories, where she tries to find her true self. For instance, she might start to question the evil deeds she was part of before.
