Well, if Ruby's mom enters the shinobi world, she would first be shocked by the cultural differences. The shinobi society is hierarchical and values things like loyalty to one's village and clan highly. She may or may not fit into this structure. Her abilities from RWBY could make her a target for some who want to study or steal her powers. On the other hand, she could also use her skills to help the shinobi world. For instance, she could use her speed and agility to perform rescue missions or help in battles against common enemies like the Akatsuki - like organizations in the shinobi world.
Her speed could be a great advantage. In the shinobi world, speed is highly valued in combat, and her RWBY - based speed could make her a formidable opponent. For example, she could quickly dodge attacks and then counter - attack before the enemy has a chance to react. Also, her weapon skills could be adapted. She might use her scythe - like weapons in new ways, perhaps combining them with some basic ninja tools like kunai or shuriken.
Well, she could change a lot of things. Maybe she'd try to prevent some of the bad things that happened in the past. For example, she might stop certain battles or warn her younger self about upcoming threats. It could also be really interesting to see how she interacts with the people from her past. Like, how would her older self deal with her old friends and foes? There are so many possibilities.
If Ruby were to become a demon in fanfiction, it would have a huge impact on the story. Firstly, the story would likely take on a darker tone. Ruby, who was once a symbol of hope, would now be a source of fear for some. Her character arc would be completely redirected. She might start to view the Grimm, which are also dark creatures, in a different light. Maybe she would see them as kindred spirits instead of enemies. Her friends would have to decide whether to try and save her or to stop her if she becomes a threat. And the overall theme of the RWBY story about friendship, courage, and fighting for what's right would be challenged as Ruby's new demonic nature tests the limits of those ideals.
If Ruby becomes a Grimm in RWBY fanfiction, it could lead to a really interesting plot. Maybe she could be a special type of Grimm that retains some of her memories and skills. This could make her a very unique and powerful entity. Her transformation might also force the other characters to re - evaluate their views on Grimm. Are all Grimm truly just mindless monsters? Ruby's case could prove otherwise.
In a fanfic where Gohan goes to the Naruto world, his presence would disrupt the balance. His Saiyan strength is on a different level compared to most Naruto characters. He might start by being confused about the ninja way and all the different clans. However, he could also introduce new concepts from his world. For example, his training methods. And he would probably make some really strange friends. Some ninjas might be in awe of his power, while others might be a bit scared. He could also end up having some really interesting battles against the strongest ninjas, like Naruto or Sasuke, which would be a clash of two very different power systems.
If Si was reborn as Ruby's twin, it could change the whole dynamic of the story. For example, they could share a special connection to the silver - eyed power. Maybe the twin would have a different take on how to use it or discover new aspects of it. This could lead to new story arcs where they have to figure out how to control and utilize this power together. Also, in the Beacon Academy days, they could be a duo that everyone looks up to, inspiring other students with their teamwork and twin synergy.
She might become more impulsive, as Saiyans are known for their bold and sometimes reckless nature. This could cause some friction within the RWBY team at first, but also lead to her learning about balance. Her relationships with her teammates would evolve as she tries to control her new powers. For instance, Weiss might be initially skeptical about Ruby's Saiyan powers but later come to respect and rely on them. Blake could see Ruby's newfound power as a way to fight against the oppression they face more effectively. Yang, being Ruby's sister, would be both proud and a bit protective, which would add an interesting dynamic to their relationship.
In such a fanfic, Ruby might gain a system that enhances her combat abilities. For example, it could provide her with real - time combat analysis, allowing her to anticipate her opponents' moves more accurately. This would make her even more formidable in battles against Grimm or other foes.
In such a fanfic, Ruby's time travel might lead to her having to hide her identity from Jaune at first. As she gets closer to him, she has to decide when and how to reveal the truth. And all this while, their relationship could be evolving in a different way compared to the original timeline. Jaune might start to fall for her in a new way, and Ruby has to deal with her own feelings for him in this altered situation.
One possible reason could be that she's on a secret mission. Maybe Ozpin sent her on a dangerous errand without telling the others to protect them. For example, he might have discovered a new threat related to Salem and needed Ruby to gather intel quietly.
