Ruby would likely have a lot of questions for her mother. Her return would open the door to learning about her family history and her own origins. This could be a very emotional journey for Ruby. She might also start to model her fighting style more after her mother, which could lead to her evolving as a fighter. At the same time, Ruby might struggle with sharing her friends and new life with her mother, as she has become so independent during Summer Rose's absence.
Her return could be a huge boost to Ruby's confidence. Knowing that her mother is there to support her, Ruby might take more risks in battles. However, it could also make Ruby more protective. She wouldn't want to lose her mother again, so she might put herself in harm's way to keep Summer Rose safe. This could lead to some interesting character development for Ruby as she has to balance her new - found family situation with her responsibilities as a Huntress.
Ruby would be overjoyed at first. After all, she has always longed for her mother. But then she might feel a bit of pressure. She might worry about living up to her mother's legacy, especially if Summer Rose is still as powerful as she was. Also, Ruby might be a bit hesitant to fully trust this 'new' Summer Rose, fearing that it could all be some kind of cruel illusion.
She could return as a sort of spirit guide, not fully corporeal. This would add an interesting dynamic as she can't interact in the physical world in the same way. Her return might also be linked to a greater threat. Like she has seen the oncoming danger in the afterlife and has come back to help the team prepare for it. It could also lead to revelations about Ruby's true potential as she inherits some of her mother's latent powers.
One possible fanfiction could involve Ruby sacrificing herself to save her friends from a powerful enemy. In this scenario, she might use her silver eyes one last time to hold off a horde of Grimm while her friends escape. Her death would be a tragic yet heroic moment, leaving her friends to carry on her legacy and the fight against evil in Remnant.
Ruby is very determined and has a strong sense of justice. If she were in Summer's shoes, she would likely be more aggressive in going after Grimm. Summer was already a great Huntress, but Ruby's impulsiveness might make Summer take on more dangerous missions. Also, Ruby is very friendly and open - minded. This could change how Summer interacted with her team. For example, she might be more inclusive of different ideas within the team, leading to better strategies.
Ruby would be more confident. With her mother there to guide her, she'd have someone to answer all her questions immediately. She wouldn't have to rely solely on Qrow or her own limited experiences. For example, in combat situations, Summer could give her real - time advice, which would make Ruby a more skilled fighter faster.
One type of fanfiction could be set in an alternate universe where Ruby uses Crescent Rose in a completely different way. Maybe she uses it for non - combat purposes like using the scythe part to cut through thick foliage in a forest she's exploring. Or it could be a time - travel fanfic where she has to use Crescent Rose to defend herself against enemies from a different era.
It would likely make her more confident. Meeting such powerful beings would show her that she is on a significant path.
She might become more cautious. Since the spider bite is an unexpected and dangerous event, she would be more aware of the potential threats around her. For example, she might be more careful when exploring new areas.
Yes, in some RWBY fanfictions, Ruby can be depicted as the Summer Maiden. Fanfiction allows for creative interpretations and alternate storylines, so it's not uncommon to see such a concept explored.
Law would likely be initially cautious around Ruby. He might be intrigued by her Silver - Eyed Warrior abilities. He could offer to help her understand and control her powers better, using his medical knowledge and devil fruit powers if there's any connection. Ruby, on the other hand, would be curious about Law's strange powers and his ship. She might ask a million questions, and Law would patiently answer some, while keeping some things to himself.
Ruby is very optimistic and determined. Scarlet Spider is often more brooding and has a sense of street - smart cynicism. Ruby's positive attitude could start to chip away at Scarlet Spider's more negative outlook over time. For example, in a tough situation, Ruby would be the one to see the silver lining and encourage Scarlet Spider to keep fighting.
