Rosalina
Rosalina is a very tall woman, standing at a staggering 6'10, which becomes closer to 7'7 when she levitates, with fair skin and cyan-colored eyes, with only her left eye visible from a directly frontal view as her particularly large bang of her hair covers her right eye. She has defined lips and long platinum-blonde hair that reaches to her waist with two hairlocks and two pairs of crescent moon-shaped parting bangs aligned vertically on each side, with the topmost pairs along her forehead, nearly touching her eyes, and the bottommost pairs closest to her neck. For makeup, she uses purple nail polish and brown mascara. Rosalina wears an aqua, floor-length dress that bares her shoulders, and it has long flared sleeves topped with powder-blue frills. The bottom of the dress has a light blue flap on the hem and turns up at a point in the middle, showing a layer of petticoat underneath. She has a star-shaped brooch with a gold gem in the middle, a silver crown enlaid with pink and blue gems, golden star-shaped earrings and silver high heels. She also wears purple nail polish. In most of her appearances, Rosalina carries a thin silver wand with a hollow golden star at the top, which is called the Star Wand. Rosalina is shown to be a wise, mature, motherly and kind woman, who has made protecting the cosmos her mission in life. She is a loving mother figure to the Lumas, which are smaller Power Stars, making Rosalina a mother of the powers of the stars, which grow into large Grand Stars, which can manipulate reality and the universe when gathered in one place. In exchange for being a mother figure, these Grand Stars gifted Rosalina with immense cosmic powers, including the ability to manipulate her own height, use telekinesis on such a level that it moves the entire Comet Observatory, flight and levitation, limited teleportation, and magics. She possesses physical skills similar to that of the other human characters. She is capable of jumping nearly as high as Luigi, although she is noted to be rather slow on her feet (even more so than Peach), but is also stronger than Wario. Despite this great power, Rosalina has been shown to be incredibly gentle, almost melancholic in her mannerisms and words And, despite these godlike powers, she's still capable of being overpowered and incapacitated, with Bower's assault on the Comet Observatory and theft of the Grand Stars right out of her hands being the chief example.
Rosalina is shown to be calm and reserved, and often takes pauses when she explains how the universe works. Her voice is rather monotone, even when she is excited, and also has a reverberating effect. Rosalina is calm, mature, motherly, and always exudes an air of authority that tames even Mario's wild tendencies, and a commanding presence that will curtail rebellious Lumas, as well as unruly visitors, no matter their age or brattiness.
