A major difference could be in her leadership style. Ruby, when raised by Summer, had a more instinctive and inspiring leadership. But with Winter, she could be more of a by - the - book leader. She might rely more on established military strategies rather than her gut feelings, which could both be an advantage and a disadvantage depending on the situation in the story.
She might be more guarded. Qrow is a cautious person, and if he raised Ruby, she would likely pick up on some of his wariness. So instead of being as open and naive as in the original series, she could be more hesitant to trust new people right away.
Her Semblance could be more destructive. Instead of using it mainly for mobility and quick attacks, it might be used to cause widespread chaos. For example, instead of just dashing in and out of battles, she could use her speed to create tornado - like effects that cause more damage to her enemies.
Another way their personalities could differ is in their sense of humor. Ruby has a more light - hearted and sometimes goofy sense of humor. The twin brother could have a drier, more sarcastic sense of humor. For instance, when Ruby makes a joke, he might respond with a deadpan comment that shows his different comedic style.
Her view of authority might be different. Since Ozpin is a figure of authority in her life, she might be more deferential to other authority figures in the fanfiction. However, as she grows and discovers potential flaws in Ozpin's methods or secrets he's been keeping, she could start to question authority in general, leading to a complex character arc.
One possibility could be that Ruby grows up with a strict military discipline under Winter. She might become more reserved and calculating in combat compared to her original carefree self. For example, she could learn advanced Atlesian combat techniques and incorporate them into her scythe - wielding style.
Well, in a time travel scenario, Ruby and Winter's relationship would change drastically. Ruby might find herself in a position where she has to rely on Winter's knowledge of the past, which could make Winter seem more authoritative in her eyes. Winter, seeing Ruby from a different time, might be more open to her ideas as she realizes that Ruby has a unique perspective from the future. Their relationship could also become more sisterly. Ruby could see Winter as an older sister figure she can confide in, and Winter could feel a sense of protectiveness towards Ruby. This could be especially true if they face threats together during the time travel adventure.
With Yang, their relationship would likely be less of a sisterly, protective one. Since Goodwitch would be in a parenting role, Ruby might not rely on Yang as much for protection. Yang might also see Ruby as more independent and grown - up, which could lead to a more equal friendship.
Ruby is quite bubbly and optimistic. Si could be more of a calm and calculating type. While Ruby might rush into battle with enthusiasm, Si would take a moment to assess the situation. For example, when facing a new type of Grimm, Ruby might immediately charge forward, but Si would first study its movements and weaknesses.
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 likely become more cynical. She's used to being in a team of heroes and believing in the good of people. But being around Cinder, who is manipulative and self - serving, would make Ruby question her own ideals. She might start to doubt the purity of her motives and become more guarded.
