Rosalina (ロゼッタ Rozetta, Rosetta) is a character that first appeared in Super Mario Galaxy, but has become a somewhat recurring character since then, especially in spin-off titles. She lives on the Comet Observatory with her adopted children, the Lumas.
She is seen as a type of sorceress, with great power. Her sole duty is to watch over and guard the universe, the Mushroom World and protect her Lumas. Rosalina's back-story is described in her story book, which is found in the Comet Observatory's Library in Super Mario Galaxy.
Nine chapters can be unlocked throughout the game, and the final one can be unlocked by completing the game. She is currently voiced by Laura Faye Smith.
Rosalina has a very similar appearance to Peach, other than resembling her. Like most other human Mario characters Rosalina has blue eyes, though hers are more cyan in color. Only her left eye is visible from a directly frontal view as her particularly large bang of her hair hides her right eye. She has peach-colored defined lips, and long platinum-blonde hair that reaches to her waist. Her primary outfit consists of a turquoise long-sleeved gown that bares her shoulders, along with a silver crown with four gems on it, a sliver star-shaped brooch, gold star-shaped earrings, and silver high heels. She notably appears in this outfit when playing golf. Like Peach and Daisy, she has a biker suit when riding bikes or ATVs in Mario Kart Wii and Mario Kart 8. Hers is primarily white and teal, to differentiate hers from those of Peach and Daisy.Her primary sports outfit is akin to the sporty minidresses of Peach and Daisy (though, again, teal), but with what appears to be white leggings instead of the other two girls' socks.Her swimwear (as seen in the fifth Mario and Sonic game) is based on those of Peach and Daisy (though teal again), but tweaked, along with sleeves to resemble her usual dress.
