Rosalina (ロゼッタ, Rosetta) is a character from the Mario series. Rosalina is the adoptive mother of the Lumas, and is among the most powerful characters within her home series, as she watches over the universe in addition to taking care of the Lumas. Her debut as a playable character in the Super Smash Bros. series was confirmed on December 18, 2013 via Nintendo Direct.
Rosalina is a youthful-looking woman whose appearance highly resembles Princess Peach. She has platinum blonde hair, styled into a bang that covers the majority of the right side of her face. She is also noticeably taller than Peach, and most Mario characters in general. Rosalina's attire consists of a turquoise empire waist dress, with tapering sleeves and a low neckline that exposes her shoulders. Her earrings and brooch display star-shaped motifs, and she wields a wand which also sports a star-shaped motif on its tip.
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 century, and functions as a home for both herself and the Lumas. Her backstory is detailed in a storybook, which 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 Luma find his mother, which eventually led to the duo building the Comet Observatory together, Rosalina coping with the death of her own mother, and subsequently forming a new familial relationship with the Lumas as their adoptive mother.
Although Rosalina has a vastly reduced role in Super Mario Galaxy 2, she 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. Her first playable appearance within the main Mario series occurred in Super Mario 3D World, where she is the game's only unlockable character and can use the Spin from the Super Mario Galaxy games.

Rosalina is a newcomer in SSB4. In addition to her own moveset, she is allied with a Luma, who has its own moveset and can assist her with almost all of her attacks. Luma can be controlled along with Rosalina, which results in the pair adhering to the "puppet fighter" archetype, similarly to the Ice Climbers. Unlike in Super Mario Galaxy and Super Mario Galaxy 2, Rosalina's dress sports star-shaped motifs, and her high heels are colored turquoise instead of silver.
Rosalina & Luma have a highly defensive neutral game, with Luma notably being able to shield Rosalina, and Gravitational Pull being able to render projectiles useless against them. When the pair are together, they can be difficult to approach, as one can cover the other and punish opponents when in danger. They also have good KO potential, thanks to Luma's standalone power and Rosalina's disjointed range. However, Luma can be KO'd temporarily; in addition to removing one of Rosalina's key strengths, a KO'd Luma renders two of the duo's special moves, Luma Shot and Star Bits, unusuable. Rosalina herself is also tall and very light, making her easy to launch. Rosalina's recovery move, Launch Star, is long-distanced and can be angled, but renders her vulnerable because of its lack of hitboxes.
Overall, Rosalina & Luma's strengths largely outweigh their weaknesses, as they have enjoyed consistent and strong tournament results. As a result, they are currently ranked 5th out of 55 on the tier list, placing them in the A tier.
