It can make her relationships strained. Ruby might push her friends away because she's afraid of hurting them or burdening them with her problems. For instance, she could be short - tempered or distant, causing her friends to be confused and concerned.
On the positive side, her PTSD could bring her closer to some characters. If there are others who have also experienced trauma, they might understand her better. They could form a support group of sorts, sharing their experiences and helping each other heal, which in turn strengthens their relationships.
It could strain her relationships. Her friends might be a bit scared or confused by her new form. They may not know how to interact with this 'Red' Ruby at first. For example, Weiss might be more hesitant to trust her, thinking that this change could make Ruby unstable.
On the other hand, it could cause some strain. If Ruby's magic is unpredictable, it might accidentally put her team in danger. This could lead to some arguments and tense moments as they try to figure out how to deal with this new aspect of Ruby. But through communication and training, they would eventually learn to work with her magic and grow even stronger as a team.
Ruby's sleepwalking might also lead to some misunderstandings. If she sleepwalks into Weiss's personal space, Weiss might initially think Ruby is being rude or inconsiderate. But once they figure out it's because of her sleepwalking, it could lead to a deeper understanding between them. Weiss might become more empathetic towards Ruby's involuntary actions, and they could become closer friends.
When Ruby becomes a demon in this fanfiction, her relationships with her team are bound to change drastically. Her new form and the powers that come with it could make her more unpredictable. Her team members like Pyrrha (if she was still around) might see her as a danger to the team. This transformation could lead to a lot of mistrust and conflict within the group as they struggle to come to terms with Ruby's new state.
The betrayal could also make her more empathetic. Ruby might start to understand why people betray others, whether it's due to desperation, greed, or being mislead. This new understanding could make her more forgiving in the long run, but also more determined to prevent future betrayals from happening within her circle of friends and allies.
The Sharingan would give Ruby a significant advantage in battles, allowing her to predict her opponents' moves. But it might also bring complications and challenges, like dealing with the power's drain on her.
If Ruby has a new identity, Weiss might initially be suspicious. Since they have a complex relationship, Weiss could think Ruby is up to something. But as the story unfolds, Weiss might see the good in Ruby's new identity and their bond could strengthen in a different way.
It can create a lot of tension within the team. The story could then focus on how they try to resolve this tension. For example, they might have to have a series of heart - to - heart conversations to understand where Ruby is coming from and vice versa. This can lead to character development for all of them.
On the other hand, it could also add depth to the understanding of the RWBY world for some. It shows that even in a fictional universe like RWBY, dark and difficult situations can exist. However, if not handled well, it might overshadow the main themes of the original series and make the overall perception more negative. For example, some fans might start to associate Ruby more with the abuse in the fanfiction rather than her heroic traits in the original show.
If Ruby becomes red, it could drive the plot by making her a target. Maybe the villains see her new form as a threat and start to focus their attacks on her more. This would create more conflict and action in the story.
