Krystal (クリスタル) is a vixen from the Star Fox series and the most recently-recruited member of the Star Fox team. She serves as the team's main telepath, additional fighter pilot, and also Fox McCloud's main love interest.
She made her first appearance in the series in Star Fox Adventures. Krystal joined Star Fox almost immediately after the Plight of Sauria, taking Peppy Hare's place as the fourth pilot. Her telepathic abilities were first seen in Adventures and put to good use during the Aparoid Invasion. 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. In Star Fox Command, Krystal left Star Fox after Fox asked her to go out the team, and joined The Cornerian Army. Sometime later, Fox returned and begged her to rejoin his team which she gladly accept it. Since none of the game's endings have been confirmed canon, the fate of Krystal and the Star Fox team after the Anglar war remains unknown, however.
