Krystal (クリスタル, Kurisutaru) is the sole survivor of her doomed home planet, Cerinia. She makes her first appearance in the series in Star Fox Adventures, where in search of answers to her planet's destruction, and the death of her parents, she comes across a distress signal from the planet Sauria. Fox allows Krystal to become a full-time member of the Star Fox team, but she soon leaves, heartbroken, as Fox fears for her safety. Various paths and endings are available in Star Fox: Command; some show Krystal returning to the team and to Fox himself, others show her defecting to Star Wolf or the Cornerian Army, or even abandoning Lylat altogether due to public ridicule and adopting a new identity under the name Kursed, changing so drastically that Fox fails to recognize her when the two cross paths on a planet named Kew two years later.
Krystal was originally designed to be a main character of Dinosaur Planet, before Nintendo turned the project into a Star Fox title. Her original design was that of a 16-year-old orphaned feline, who was raised by a wizard named Randorn. When Fox became the main character of Adventures, Krystal was redesigned into her present form as a 19-year-old orphan, and her role in the game became less central. In the English version of the series, Krystal has a British accent and is voiced by Estelle Ellis in Adventures, and Alésia Glidewell in Assault. In Japanese, she is voiced by Aya Hara.
Krystal appears in Super Smash Bros. Ultimate as an assist trophy.
