Her Personality: 

Rosalina is a generally wise, kind, and a mature character. She has an intimate knowledge of the universe and cares deeply for the Lumas and her friends, where she assumes the role of the total caregiver and mother figure for them. Her outward strength and inner sorrow are likely due to the loss of her own mother. Rosalina is a calm and reserved character, and often takes pauses when she explains how the universe works. It has also been shown that Rosalina's voice is rather monotone, even when she is excited. Since Mario Kart Wii, however, Rosalina has been portrayed as a little bit more upbeat and joyous than her original portrayal, with examples being that Rosalina cheers and shouts louder, though still mostly keeping her introverted nature. Like most players, Rosalina enjoys special activities, but in a very humble manner.

When Rosalina was young, she was portrayed as optimistic and proactive, where she helps a Luma build a spaceship to find the Luma's mother instead of doing nothing. Even so, she gets homesick and misses her mother dearly, to the point where she cries about losing her mother, though her spirits get raised easily when the Lumas impress her with comets and that they offer to take her back to her home planet.
