Krystal is a vixen who hails from the planet Cerinia, having joined the Star Fox team after the Plight of Sauria, as the most recent member and taking the retired Peppy Hare's place as the fourth pilot, at least until she was told to leave the team before the Anglar Wars began. She serves as the team's telepathic advisor, additional fighter pilot and she's also Fox McCloud's main love interest (although sometimes he's in competition with Panther Caroso, who's also infatuated with her). Her telepathic abilities were first seen when interacting with the native Dinosaurs on the planet Sauria and putting her extra sensory perceptive foresight to good use during the Aparoid race's invasion of the Lylat System. Using her abilities, she can read thought patterns and sense Distress Signals, which is vital for the Star Fox team as they help out other planets.
