Rosalina, known in Japan as Rosetta (ロゼッタ, Rozetta), makes her first playable appearance in Mario Kart Wii, where she is a large-sized unlockable character. Rosalina rides in large karts, and is the first female character to ever be in this class. While racing, a Luma orbits around Rosalina. Rosalina's racing symbol is a Grand Star. Like Peach and Daisy, Rosalina appears in a biker suit while racing on any of the motorbikes, but her biker suit's color scheme is different to the overall color scheme of her main dress. Rosalina is the staff ghost character for Rainbow Road, and is also the only female Large-Sized character in the game.
Rosalina has a very tall frame in comparison to other female characters within the series, being about as tall as Waluigi. As a result, she is classified as a large-class character in Mario Kart Wii. Rosalina's skin is very fair, being a pallor white, and her facial features are similar to Princess Peach's, but sharper. Her eyes are similar to Peach's as well, but are more almond-shaped and have a deep, brown shade to her lashes rather than black. Like other main human characters, Rosalina has blue eyes, though hers have a noticeably cyan hue.
Rosalina's hair is depicted as a platinum-blonde, a much lighter shade than Peach's yellow-blonde. Rosalina's hair style is very similar to Peach's, as it consists of two separate flips on the sides in the same shape. Unlike Peach's hair, Rosalina's includes one large bang (which covers her right eye completely), two long, shaped ear-tails, and two rows of flips at her shoulder. Continuing from her shoulder is a large single flip down her back. Rosalina currently appears in a turquoise evening gown; her pendant and tiara are shaped after a silver star. Her earrings are also star shaped, but yellow in color.
Unique when playing as Rosalina is that you also have a Luma that orbits around you. When you go off jumps, the Luma will squeal and cheer with joy or chuckle.
