Rosalina wears a silver crown, has platinum blonde hair with a side-fringe, a frilly light blue dress, and carries a wand. When she is driving (Mario Kart Wii only), a small, yellow Luma floats around near her head.
In Super Mario Galaxy, Rosalina made her first appearance when she taught Mario and Luigi the Star Spin. The player also may optionally view Rosalina's shrouded past in the Comet Observatory's Library through unlocking chapters of Rosalina's storybook, while progressing through the game. The mysterious storybook read by Rosalina herself details how she came to meet the Lumas and build the observatory, as well as her childhood struggle to overcome her mother, father, and brother's deaths.
Rosalina appears in a non-playable role in Super Mario Galaxy 2. A "cosmic" version of herself also appears as part of the game's 'Cosmic Guide.' At the end of the game, after Mario saves Princess Peach, Rosalina comes in front of Starship Mario and thanks Mario for saving her lost one and the universe.
In Super Smash Flash 2, Rosalina appears as a background character in the Comet Observatory in the front of the beacon. Around her, there is a black Luma called Polari. She was removed from the game, along with Comet Observatory, for unknown reasons.
