Why hello there humble visitor. What brings you here? Well, since your here my name is Princess Rosalina, Protector of the Lumas and princess of the Galaxies. I first appear in the Gateway Galaxy, I also command the Comet Observatory. I guess I'm a very powerful figure, as my duty is to watch over and protect the cosmos as well as the Luma.
I'm generally wise, kind, thoughtful and mother-like. I have an intimate knowledge of the universe and care deeply for the Lumas. I'm is also a friend of Mario and Luigi; towards the end of Galaxy I aid Mario to reach Bowser in order to save Peach. My outward strength and inner sorrow is most likely due to the loss of my mother, as I'm often described as feeling lonely.
It has also been shown that my voice is rather monotone; even when I'm excited. Like most Mario characters, I enjoys special activities such as sport, ect, but in a very humble manner.
I have special powers as seen in Super Mario Galaxy. For example, once sufficient power is restored to the Comet Observatory, I'm able to use my powers to surround the observatory in a force field, transforming it into a starship as a form of transportation. Also, I can be protected by a force field that resembles a bubble. If the player attempts to jump on me, the bubble would appear. I also has the ability to float in mid-air, just like the Lumas. Referenced by the fact that I visits the Mushroom World every one-hundred years, I'mj apparently immortal or has stopped aging. Alternatively, I may in fact age normally. If I'm usually traveling through the universe at near light speed then, according to the theory of special relativity, much less time would pass for me than would pass back on the Mushroom World due to time dilation. In this case I may in fact still be a young woman.
One of my most notable relationships is with the Lumas. I have cared for the Lumas since I was a little girl, when I found one looking for its mother. We quickly bonded and we searched the galaxies together in search of their missing mothers. The Luma comforted me when I cried about my mother and then we soon found more Lumas. I then decided to build a home for the Lumas and care for them for eternities to come. When I once again mourned for my mother, all of the Lumas embraced me and together, they baked a cake topped with Star Bits. I also read them bedtime stories every night in the Library to help them sleep. One of my most trusted advisers is also the Luma, Polari. That's all I have in my head right now. Come back and visit!
