Kursed is Krystal's bounty hunter alter ego and a minor antagonist of the videogame Star Fox: Command.
In the 4th Ending of Star Fox: Command, Krystal betrays Star Fox and steals their flagship, the Great Fox, leaving Fox McCloud and his team stranded on Katina. Taking Leon Powalski and Panther Caroso with her, they meet with Wolf O'Donnell on Venom, where they defeat the Anglar Emperor themselves. After Star Wolf's victory over the Anglars, Wolf still feels unsatisfied.
Krystal explains that it was because they had to betray Star Fox to do so. Leon, on the other hand, is overjoyed that they can get the bounty lifted, and expects a celebration in their honor. Indeed, Star Wolf is praised for their efforts, but the people of Lylat are less kind to Krystal, believing that Krystal was wrong to swindle Star Fox the way she did.
Eventually, the comments of the populace become unbearable, as they start to hiss as she walks by, or would even call her a traitor to her face. She pulls away from Star Wolf to find a new life, fleeing to a distant galaxy and changing her name to Kursed (though the Japanese version contradicts it). She becomes a Bounty Hunter, chasing the worst in the galaxy in her visibly wearing out Cloud Runner, and making as ruthless decisions as possible to get her jobs done. She runs into Fox years later on planet Kew, but she has changed so much, Fox did not recognize her. It is most likely Krystal decided not to tell Fox who she was, either.
