Ever since she was little, Ruby has had a romanticized view of the Huntsman profession. She is quick to reveal she wanted to become a Huntress in order to be like the great heroes in fairy tales, and she has described being one as far more "romantic" than being a police officer. Her mentality is described as "I don't have time for my emotions. I've gotta make sure that everybody else is okay." She has also shown a distinct lack of ability picking up social cues due to being a very open and honest person.

Although Ruby has no trouble interacting with friends, she does have trouble actually making them, and once admits that seeing new weapons "is like meeting new people, but better". This could have been a result of her having been accepted two years earlier to Beacon Academy, which forces her to leave her friends at Signal behind, as well as interact with people that are both older and more experienced than she is.

Ruby also has a sweet tooth, preferring five sugars in her coffee and scarfing down a large plate of cookies in "Ruby Rose".
