Princess Rosalina

Princess Rosalina Estela (dubbed Rosetta in Japan; simply known as Rosalina or Princess Rosalina) is a character based on the Super Mario character of the same name.

Rosalina made her debut in Super Mario Galaxy, and has made a good number of appearances outside the Super Mario Galaxy series since.

No matter what game she is in, Rosalina will always have her Luma with her. This is clearly evident in the Super Smash Bros. series, and the Mario Kart series.

Rosalina did not receive a Sports outfit of her own until Mario Tennis: Ultra Smash. It was thanks to this game that all three Mario Princesses had at least one Sports outfit.

Princess Rosalina recently receive a Gymnasium/Swimming suit in Mario and Sonic at the Rio 2016 Olympic Games. She is only playable in the Gymnasium events.

Voice Actress
Princess Rosalina is currently voiced by Laura Faye Smith.

She was previously voiced by Kerrie Kane and Mercedes Rose, her very first voice actress.
