The Cloud Runner is a personal spacecraft used by Krystal, which she designed and based its appearance from the CloudRunners, a dinosaur tribe native to Sauria, making it lose all features of the Arwing's recognizable appearance. It is armed with a Twin Laser, Single Lock and one Smart Bomb and it has a two-second time bonus. When Krystal is asked by Slippy Toad how the ship is handling, Krystal responds that she thought that she'd be flying "her" again, which implies that the ship had been constructed long before Krystal was forced off the Star Fox team.
When the "Star Wolf Returns" ending is achieved, Krystal undergoes a change in identity and adopts her new alter ego, a bounty hunter named "Kursed", but still flies her worn out Cloud Runner ship.
