One character could be Nora. Nora is energetic and fun - loving, just like Ruby in some ways. Their combined energy could make for a very lively threesome scenario in fanfiction. Ren might also be a candidate. Ren's calm and collected nature would contrast well with Ruby's more exuberant personality. Together with another character, perhaps Weiss, they could form an interesting threesome. Also, Emerald could be in a threesome with Ruby. Emerald has her own motives and a somewhat complex personality. Her interactions with Ruby, especially in a threesome situation, could add a lot of depth to the fanfiction.
Some popular themes could be adventure. Ruby often goes on various quests in RWBY, and in fanfiction this could be incorporated into a threesome scenario. For example, she and two other characters might be on a dangerous mission and their relationships develop during that. Another theme could be friendship. The threesome could be about strengthening the bond between Ruby and the other two through shared experiences. It might also involve themes of self - discovery, where Ruby learns more about herself in the context of this new relationship dynamic.
In addition to the obvious ones, Glynda could play a role. As an associate of Ozpin, she may have some interactions with Ruby. Also, the villains in the RWBY universe might target Ruby more because of her new connection to Ozpin. So characters like Cinder or Salem could potentially interact with Ruby in the context of this fanfiction, either directly or through their minions. This would add a whole new layer of danger and intrigue to Ruby's story.
Well, Weiss would likely be one of the main characters to interact with Ruby. They have a complex relationship in the original series, and in this fanfiction as Ruby is a big sister figure, Weiss might come to her for advice on things like family expectations or her own growth as a Huntress.
Definitely her team members Weiss, Blake, and Yang. Since they are always by Ruby's side in the original RWBY series, they would play important roles in this fanfic as well. They might be the ones to first notice Ruby's change and try to help her understand and control it.
Weiss could be one of the characters. Since she's part of Team RWBY and has a complex relationship with Ruby, it would make sense for her to be involved. Another one might be Blake. She has her own story arc and her relationship with Ruby could be explored through these kisses.
Well, obviously Ruby herself. Then there's her teammates Weiss, Blake, and Yang. Depending on the nature of the relationship in the fanfiction, Yang might be deeply affected if it's a family - like bond that's breaking. Weiss could be involved in trying to mediate or give her two cents on the situation from her logical perspective.
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.
Blake is also a common character to be paired with Ruby. There could be fanfictions where they team up for a special mission that is different from the main storyline. For example, they might have to infiltrate a secret organization together, relying on each other's unique skills.
In some cases, new original characters might be introduced. These could be other hunters or huntresses who have a connection to the source of Ruby's darkness. They could either be helping Ruby or be part of the problem. Maybe they are also victims of the same dark power that is corrupting Ruby and they both have to find a way out together.
Another likely combination could be Rory, Jess, and a new character. Jess has a special place in Rory's heart. Adding a new character to the mix could introduce a fresh perspective. The new character might be someone who challenges Rory's feelings for Jess and vice versa. The threesome could be a way to explore how Rory's past love for Jess still lingers while she's also open to new experiences with this new person.
