Well, if they watch an anime like 'Neon Genesis Evangelion', their view of self - sacrifice and the weight of the world could change. They might start to question their own roles more deeply. For example, Ruby might realize that being a hero isn't always as straightforward as she thought.
After watching 'Attack on Titan', RWBY's view on survival and the fight against overwhelming odds would likely be affected. They would see how the characters in AoT are constantly pushed to their limits. Yang might become more cautious in battle, realizing that there are threats out there that are truly terrifying. Weiss could start to think more about the long - term strategy for survival in their own world. Blake might understand the importance of unity in the face of a common enemy better, as the characters in AoT rely on each other to survive.
Ruby might start to think more about different fighting strategies. Seeing all the creative battles in the fanfiction could make her realize there are many more ways to approach a fight than she initially thought.
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.
Their worldviews could become more complex. They'd realize that not all battles are against inhuman monsters like Grimm. The human - on - human conflict in WW2 would show them the darker side of humanity that they may not have fully considered in their own world.
For Ruby, reading Naruto fanfic could expand her view of heroism. In Naruto, the hero often has to struggle with inner demons and the expectations of the village. This might make Ruby think more about her own role as a huntress and the different ways she can inspire others. Yang could see how the characters in Naruto deal with loss and come back stronger, which might influence how she views her own past traumas.
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.
Ruby would start to think about how the RWBY team could be more organized like the Earth military. She might see the value in having a more structured approach to fighting Grimm. Weiss would look at the Earth military's technology and wonder why Remnant hasn't developed similar things. This could lead her to question the reliance on Dust. Blake would be influenced by the way the Earth military works together. She might consider how the different faunus groups could cooperate better in Remnant. Yang would be amazed by the endurance and teamwork of the Earth military soldiers. This could make her more patient and less reliant on her own individual strength when fighting.
Yang and Blake's relationship could be affected in a positive way. Yang might make jokes about the fanfiction that Blake finds funny, strengthening their bond. Weiss could become more open to different types of stories, which would change her interactions with the team. Ruby would be the driving force in getting everyone involved in the discussion about the MLP fanfiction, making the team more united in their shared interest.
In many RWBY Reincarnation fanfictions, Ruby often becomes more introspective. Her reincarnation forces her to look at herself in a new light. For example, she might question her past actions and decisions. She may also become more cautious as she adapts to the new world she's in.
They might gain new perspectives. For example, they could see different interpretations of Jack's character, like a more vulnerable side that wasn't as explored in the original show. This could make them understand his struggles better.
Ruby and Yang might start sparring more, trying out some of the crazy battle scenarios they saw in the fanfic. Weiss and Blake could have deeper discussions about the character relationships in the fanfic, which could in turn strengthen their own relationship. Overall, they would have a better understanding of each other's perspectives on battles and relationships.
