A new group of Grimm hybrids created by Salem could be the main antagonists. These hybrids could be specifically designed to hunt down the wolf pack. They would have the intelligence of humans (from Salem's influence) and the ferocity of Grimm. The wolf pack, led by Ruby, would have to figure out the weaknesses of these new enemies and fight to protect themselves and the people of Remnant.
It could be Salem's forces. Since Ruby is now a Maiden, Salem would likely want to either turn her to her side or eliminate her to prevent her from being a threat to her plans.
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.
The White Fang could be antagonists, seeing Ruby as a symbol of human - made abominations (in their view) with her cyborg body. They might target her to make a statement against humans.
One common theme is transformation. Ruby often undergoes some kind of transformation related to her wolf - like nature. It could be physical, like growing claws, or more of a spiritual change where she becomes more in tune with her wild side.
One possible main antagonist could be a powerful Grimm lord that has emerged. This Grimm lord could be far more intelligent and organized than regular Grimm, and it sees Ruby's growing army as a threat to its plans of total domination. It could send out waves of Grimm to attack Ruby's army during its formation, trying to disrupt and destroy it.
In fanfiction, a male wolf faunus and Ruby could have a very interesting relationship. Maybe they start as comrades in battle. The wolf faunus could use his natural instincts and physical abilities to protect Ruby. Their relationship might also be based on mutual respect for each other's skills. For example, Ruby's scythe - wielding skills and the faunus's combat skills could complement each other well in combat situations.
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.
One great RWBY Wolf Ruby fanfiction is 'Ruby's Wolfish Adventure'. It delves into a unique storyline where Ruby discovers her wolf - like abilities and how they change her role within the team. The story is full of action and interesting character development.
Well, her sister Yang would definitely be one of the main characters. Yang would be very protective of Ruby and would try to help her in any way she could. Weiss would also be important. She might use her intelligence and Dust - related skills to assist Ruby. And Blake, with her stealth and combat skills, could be crucial in protecting Ruby and guiding her through difficult situations.
It depends on the specific fanfiction. Ruby's location could vary based on the plot and creativity of the author.
