Character description
Rosalina debuted in Super Mario Galaxy, where she is a major non-playable character. She commandeers the Comet Observatory, which visits her home planet once every 100 years, and functions as the home of both her and the Lumas. Her backstory is also explained in a storybook that she reads to the Lumas at various points during the game. The storybook reveals that Rosalina first journeyed into outer space to help a lost Lumafind his mother, which eventually led to them building the Comet Observatory, Rosalina finding out about the death of her own mother, and her forming a new family relationship with the Lumas as their adoptive mother.

Rosalina also appeared in Super Mario Galaxy 2, but has a vastly reduced role, as she only appears during the end of the game's story to reunite with Luma after he assisted Mario in defeating Bowser. However, Rosalina will also appear on Starship Mario after the player collects all 242 Power Stars.

Following these appearances, Rosalina made her first playable appearance in Mario Kart Wii and has been playable within the Mario Kart series and a number of other Mario spin-off games ever since. However, her first playable appearance within the main Mario series occurred in Super Mario 3D World.
