In the first series, Ruby is very air-headed, joyful, brash, happy and is a big troublemaker, who sometimes wants to go her own way, despite being told to stop at one place.

In Lady Jewelpet, Ruby is very air-headed and doesn't really know how to teach Momona the right things. She can't tell when someone is insulting her and takes it as a compliment instead. When in a panic, she does things on impulse and often hurries off to do what she has to do. However, Ruby still manages to be very optimistic.

In Jewelpet Attack Chance!?, Ruby has a lazy attitude who doesn't like to get things done. She also has a huge appetite for food than she does in the original anime.

However, its reliability is varied (even after Ruby had been upgraded to Super Crystal Class by learning a new lesson of courage and had been trained with Labra to temporarily upgrade her magic in order to summon Opal, her magic still causes explosions). Ruby can also use the Jewel Pocketbook alongside Rinko to awaken Jewelpets from their jewel forms.
