RWBY could improve their teamwork. Some fanfictions focus on the relationships between characters. By watching these, they could learn how to communicate better, support each other more effectively, and anticipate each other's needs. Moreover, they could also learn about different emotional states and how to handle them. For instance, if a fanfiction shows a character dealing with grief, they could learn how to be there for each other in tough times.
They could gain new perspectives on their own characters. Fanfictions often explore different sides of the characters that may not have been fully shown in the original work.
They could gain new perspectives on action - oriented storytelling. The fanfiction might offer unique twists on combat and strategy that they can apply in their own battles.
RWBY could expand their knowledge of different fantasy worlds. The Dark Souls fanfic might introduce them to new concepts like the unique magic systems or the way the afterlife is depicted. This could give them ideas for their own world - building or for new techniques in combat. Also, they could learn about different ways of character development. In Dark Souls, characters often grow through repeated failures and hardships, which is a bit different from how RWBY characters usually develop. This new approach could be something they could incorporate into their own growth as heroes.
They might be confused at first. RWBY has its own unique lore and concepts that are different from many anime. So anime characters may need time to understand things like Grimm and Huntsmen. For example, if Goku from Dragon Ball was watching, he'd probably be like 'What are these strange monsters?'.
There are indeed some interesting ones. A lot of RWBY fanfictions explore different aspects of the Remnant world. For example, some might focus on the backstories of the villains. It can be really fun to read these while watching the anime as it gives you a deeper understanding of the RWBY universe.
Ruby might realize that she's seen as a symbol of hope by a lot of fans, which could make her even more determined to live up to that. Weiss could see that some fans think she's too cold, and she might try to be more approachable. Blake might understand that her past is something that really fascinates fans, and Yang might notice that her protectiveness of Ruby is a big part of how she's perceived. Overall, their self - perception could shift based on these fan - created views.
There could also be some tensions. If the fanfiction shows a future where there are misunderstandings or conflicts between certain characters, it could create uneasiness in their current relationships. For example, if Blake and Weiss are shown to have a falling - out in the future, they might start to be more cautious around each other and try to avoid the potential issues that could lead to such a situation.
It could inspire them to add more complex power systems. Just like Naruto has different chakra natures, RWBY could think about more diverse ways of using their auras. For example, they might consider something like elemental auras.
For Weiss, it could shatter some of her preconceived notions about class and status. In the alternate universes, these concepts might be very different. Blake could gain new perspectives on the Faunus - human relationship. The fanfictions might show unique solutions to the problems in their own world. Yang might become more aware of the power of different Semblances. By seeing how they are used in alternate universes, she could think of new ways to use her own.
It could inspire new combat techniques. For instance, if they see a Servant using a unique form of magic - based combat, they might try to adapt it to their own fighting styles. Ruby could learn about strategic use of different powers from the Fate Zero characters and apply it when facing tougher Grimm.
