Princess Daisy is a recurring character in Nintendo's Super Mario franchise, debuting as the princess of Sarasaland in Super Mario Land, released for the Game Boy in 1989. In this title, developed by Nintendo R&D1 and directed by Gunpei Yokoi, Daisy serves as the primary objective for Mario's adventure, having been kidnapped by the alien antagonist Tatanga, who seeks to conquer her kingdom. Sarasaland, distinct from the Mushroom Kingdom, comprises four unique worlds inspired by real-world cultures (Birabuto resembling Egypt, Muda evoking underwater themes, Easton drawing from Easter Island, and Chai reflecting ancient China). Following her rescue, Daisy became a largely dormant character for over a decade, with only minor cameos, such as appearing as Luigi's golf partner in NES Open Tournament Golf (1991).
Daisy's modern characterization and design solidified with her reintroduction as a playable character in Mario Tennis for the Nintendo 64 in 2000, developed by Camelot Software Planning. She is portrayed as an energetic, tomboyish, and competitive princess with short brown hair, blue eyes, and a signature yellow-orange dress featuring floral accents and white panniers. In contrast to the more elegant and reserved Princess Peach, Daisy exhibits a bold, outspoken personality, often accompanied by enthusiastic gestures and her recurring catchphrase, "Hi, I'm Daisy!" Her athletic prowess and feisty demeanor make her a frequent participant in sports-themed titles, where she demonstrates abilities in tennis, golf, kart racing, and various party games.
Since her revival, Daisy has become a mainstay in Mario spin-off series, appearing consistently in entries such as Mario Kart (from Double Dash!! in 2003 onward), Mario Party, Mario Golf, and Super Mario Bros. spin-offs. A significant development occurred in Super Mario Bros. Wonder (2023) for the Nintendo Switch, where she was included as one of the default playable characters in a mainline 2D platformer for the first time, complete with unique animations and abilities like floating. She also features as an Echo Fighter of Peach in Super Smash Bros. Ultimate (2018), further expanding her presence. While primarily associated with multiplayer and sports games, Daisy's enduring popularity stems from her distinct personality and consistent inclusion across Nintendo's broader Mario ecosystem.
