A plot could revolve around a wolf Faunus who has a connection to Ruby's past. For example, the Faunus knew Ruby's mother or some other relative. This connection could bring out secrets about Ruby's family and also help in character development for both Ruby and the wolf Faunus. Or perhaps the wolf Faunus is a part of a secret Faunus society that Ruby stumbles upon, and she has to navigate the politics and power dynamics within that society while also maintaining her own values.
One idea could be Ruby meeting a wolf Faunus who is initially mistrusted by the group but later proves to be an ally. Maybe the wolf Faunus has a special ability related to tracking that helps Ruby and her team in a mission. Another plot could involve a wolf Faunus who is being hunted by some anti - Faunus group and Ruby decides to protect them, which leads to a series of battles and the exploration of the discrimination against Faunus in the RWBY universe.
One plot idea could be Ruby struggling to hide her Faunus identity at first. Maybe she has cat ears as a Faunus and has to constantly keep them hidden under her hood. Another idea is that she discovers a unique Faunus ability that she has to learn to control. For example, she might be able to communicate with certain animals in a way no one else can.
Well, one idea could be that Ruby's dragon faunus side is awakened by a powerful relic. And then she has to quickly learn to control her new powers. Another is that she discovers she has a special bond with a dragon - like Grimm, which is really strange as Grimm are usually just evil entities. This bond could make her question the nature of Grimm and faunus.
A popular one might be the fanfic that delves into Ruby's backstory as a wolf faunus. It could explore how she got her abilities, her family's connection to the wolf faunus heritage, and how it all ties into her role in the RWBY story. It may include some really emotional moments as she discovers more about herself and her place in the world.
One way is through shared experiences. For example, if they go through a difficult battle together. Ruby could see the wolf Faunus's fighting skills and courage, and the Faunus could see Ruby's leadership. Another way is mutual understanding. The wolf Faunus could share their story of being a Faunus in a world that often discriminates, and Ruby could share her own insecurities and dreams. This would create an emotional bond between them.
Another plot could be that the wolf pack is actually a group of transformed Huntsmen and Huntresses who were cursed. Ruby, with her pure heart and determination, tries to find a way to break the curse while also dealing with the challenges of keeping their secret from the rest of the RWBY world. She could face internal struggles within the pack as some members are more accepting of their new forms than others.
There are fanfictions where Ruby is a Faunus herself. Maybe she has some kind of cat - like Faunus trait. This would change how her teammates interact with her at first. For example, Weiss might have some initial prejudices to overcome, but as the story progresses, they all come to accept Ruby for who she is, Faunus or not. It could be a story about acceptance and friendship in the face of differences.
One idea could be Ruby facing a new type of Grimm that has unique abilities, like the ability to manipulate time in a small area. This would put Ruby in a tough situation where she has to figure out how to combat it while being affected by the time distortion. Another plot could involve Ruby getting lost in a Grimm - infested area and having to rely on her wits and the little resources she has to survive and find her way back to her team.
Perhaps the story could explore how Ruby's pregnancy affects her relationships with her team members. Some might be overly protective, while others could struggle to accept the change in her situation. It could also be interesting to see how her pregnancy impacts her relationship with her weapon and combat abilities.
One plot idea could be that Ruby, as a Faunus, has some unique abilities related to her Faunus nature that she and Blake discover together. They go on adventures to understand and control these abilities while also strengthening their relationship.
In RWBY fanfiction, the male wolf faunus and Ruby could interact in a mentor - mentee way. The faunus, with his more experienced nature, could guide Ruby in certain aspects of combat or survival. For instance, he could teach her how to better sense danger in the wild, like a wolf does.
