One idea could be that Naruto, who somehow ends up in the RWBY universe, teams up with Blake. They could share their experiences of being outcasts in their own worlds. Naruto's determination and his never - give - up attitude could inspire Blake, and in turn, Blake could show Naruto the unique Grimm - fighting skills she has.
Another possibility is a story where there is a threat that requires both Naruto's chakra - based powers and Blake's semblance. For example, a powerful new type of Grimm that can only be defeated by combining Naruto's Rasengan with Blake's shadow clones. This would force them to train together and learn about each other's abilities and cultures.
One idea could be Ruby and Blake getting lost in a mysterious forest during a mission in Volume 5. They have to rely on each other's skills, Ruby's speed and Blake's stealth, to find their way out. Another could be that they discover a long - lost relic together and have to protect it from a group of Grimm.
A fanfiction could be written about a school project in Volume 1 that Ruby and Blake are paired up for. At first, they struggle to work together because of their different personalities. But as they research and present their project, they find common ground and start to see each other in a new light, leading to a closer relationship.
A plot idea might be that Ruby and Blake are sisters separated at birth. Ruby was raised in Patch while Blake was in Menagerie. They find out when they both start having strange abilities that are related to their shared heritage. For example, they can communicate telepathically during times of great danger. As they explore this new connection, they also have to deal with the fact that there are some in the world who would see their union as a threat to the status quo. They then have to fight to protect their sisterhood and the world at the same time.
One common theme is friendship. Since both Naruto and Blake are characters who value their friends deeply, many fanfictions explore the development of their friendship when they interact. Another theme is the clash of different worlds. Naruto comes from a ninja - filled world and Blake from the RWBY universe, so there's often a focus on how their two very different worlds' elements interact and collide.
One idea could be a fanfiction where Blake's ears get injured during a battle. This would not only affect her physically but also emotionally as her ears are such an important part of her Faunus identity. Her friends would then have to help her deal with the injury and the resulting self - doubt.
Well, a great plot might be that Blake discovers a hidden power within herself. This power could attract both friends and foes alike. She might have to deal with the jealousy of some of her comrades while also trying to master this new ability. Or perhaps she gets caught in a political intrigue between different kingdoms in Remnant, and her actions as a Futa character could bring a new perspective to the story.
A possible fanfiction could focus on a team-up between RWBY and Naruto characters against a common enemy that has the power of both Grimm and some dark ninja jutsu. For example, they might have to face an evil organization that is using Grimm to create chaos in the Naruto world while also using forbidden ninja arts. Or perhaps a fanfic could explore the concept of a RWBY character having a Sharingan - like ability that they gain in the Naruto world and how it changes their combat style and relationships with others.
One interesting idea could be the combination of Naruto's ninja abilities with RWBY's unique combat styles. For example, Naruto's shadow clone jutsu might be used in creative ways in the RWBY universe, like having clones perform different team maneuvers simultaneously. Another idea could be the exploration of immortality in the context of both worlds. How would an immortal character interact with the challenges and power dynamics in Naruto and RWBY? It might also involve crossovers of characters' relationships, like how Naruto's friends would get along with RWBY's team members.
One idea could be a tournament where characters from both universes participate. It would be exciting to see Naruto's ninjutsu against RWBY's weapon - based combat skills. Another is a story where they have to team up to stop a common enemy that has the ability to disrupt both their worlds, like a powerful demon or an ancient evil.
Perhaps there could be a story where an ancient evil threatens both universes. Naruto and Neo RWBY characters have to work together to find a way to stop it. The Akatsuki from Naruto could be involved, and some of their goals could be related to the chaos in the RWBY universe. Ruby and Naruto could form a special bond as leaders of their respective groups, leading the charge against this great threat.
