The Daytripper and Birthday Girl (Royal Ribbon in the British English version) from Mario Kart Wii and Mario Kart 7 respectively could be considered the Royale's successor, as well as the Cat Cruiser from Mario Kart 8 and Mario Kart 8 Deluxe due to its "feminine" designs.
In the Mario Kart series
The Royale debuted in Mario Kart DS, as one of Princess Peach's karts in Mario Kart DS, the others being Standard PC and the Light Tripper. The Royale offers amazing Drift and Items, but lacks in Speed and Handling, while Acceleration and Weight are average. This and Toad's 4-Wheel Cradle are the heaviest karts within the lightweight class.
Its acceleration is tied with Mario's B Dasher, its weight is equivalent with Wario's Brute, and its handling is shared with Wario's Dragonfly. It shares its items stat with each character's heavier karts.
Yoshi and Toad can use the Royale once the player completes all cups in the 150cc Nitro or Retro Grand Prix, and all racers can use the Royale once all cups in the Mirror Class have been completed.
The Royale returns as a kart in Mario Kart Tour, where it is classified as a Super kart. The game also introduces a white variant, simply called the White Royale.
