I received a garbled distress signal. It said something about a mountain hidden in a storm. Whoever they are, they sound in great danger!
—Krystal, Star Fox Adventures (first line)

Krystal is a blue-and-white vixen and the most recently-recruited member of the Star Fox team. She serves as the team's main telepathy, additional fighter pilot, and she is also Fox McCloud's main love interest (although Panther Caroso is also infatuated with her). She made her first appearance in the series in Star Fox Adventures. Krystal joined Star Fox almost immediately after the Saurian Crisis, 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 team as they help out other planets.



Krystal is a female fox native to Cerinia, a planet outside of the Lylat System. Krystal became proficient in using a powerful staff weapon, as well as her natural abilities of telepathy.

Plight of Sauria

Cerinia was reported to be completely destroyed in an unknown disaster in which Krystal was the only known survivor. Krystal, seeking answers concerning her home planet's destruction, journeyed to the Lylat System, where she came to Dinosaur Planet (later known as "Sauria") after receiving a distress call during her search.

Upon arriving at Dinosaur Planet, the source of the signal, Krystal immediately learned of the troubles of the planet's natives, and their peril at the hands of General Scales and his SharpClaw army. General Scales had attacked the Krazoa Palace and caused the six Krazoa Spirits to flee from their sanctuary. The Krazoa Spirits scattered all over the planet, and began to die. At the same time, the planet itself began to break apart, poised to explode.

In an effort to turn the tide of war and undo the damage Scales wrought, the young vixen agreed to help the dinosaurs return the six Krazoa Spirits to the Krazoa Palace and save Dinosaur Planet from destruction. However, Krystal only fared as far as retrieving the first Krazoa Spirit from the bowels of the temple. Upon releasing the spirit into the temple's interior, she was attacked by an unknown assailant (who would later reveal himself to be Andross) who imprisoned her in a crystalline cell at the top of the palace. Krystal would remain there until all of the Krazoa Spirits were reunited. Seconds before being imprisoned, she ended up recognizing her attacker.

Krystal's life-force began to be drained by the crystal, until Fox McCloud of the Star Fox Team arrived to save the planet. Fox first contacted Krystal via her Staff, which he retrieved from the ground after Krystal lost it while in mid-air combat with Scales' galleon after her arrival. Krystal had left telepathic instructions on how to use it, and Fox quickly learned how to use it to aid in his mission. Fox was directly contacted by Krystal when he heard the echoes of her telepathic cries for help in Saurian language, then a Krazoa Spirit Krystal released implored Fox to save her, which he was initially reluctant to do, but then became determined to once he eventually saw her in person, still trapped in the crystal.

After the Krazoa Spirits were returned to the palace, Krystal was freed from her incarceration, only to quickly brush Fox aside to take the staff from him. It was at this time Andross revealed himself, having used the energies of the Krazoa, and Krystal herself to revive himself. Krystal attempted to shoot Andross down with her staff as he departed to conquer the Lylat System, but it proved ineffective, and Fox journeyed into space in his Arwing to defeat his arch-nemesis once again.

In the aftermath that followed, Krystal sought to apologize to him for her actions and thank him for all of his help. Krystal initially sent this as a message, but then she also docked in the Great Fox to thank Fox and his assembled team in person. Fox responded in a rather shy manner, and was met with teasing from a couple of his fellow crew members. ROB 64 noticed and reported Fox's rising temperature for everyone to hear. Fox replied that he'll be just fine, as he and Krystal shared a smile to each other.

Aparoid Invasion


During their trek to Fortuna after Oikonny retreated from the space battle to the planet, Krystal demonstrated her telepathic abilities by quickly warning the team that Oikonny's forces are preparing an ambush when they arrived at his base. After team Star Fox skirmished with a strange creature on Fortuna during a rebellion started by Oikonny (an encounter that almost resulted in her death due to the creature firing a blast at her ship and hitting it), they discovered that the creature was an Aparoid, whose species was to invade the Lylat System.


The team were dispatched there to locate a distress signal, and while Krystal wanted to assist Fox directly, she was instead ordered with the rest of the team to cover him with Arwing support. Krystal briefly ran into trouble, but was rescued by Fox. An Aparoid Walker attacked McCloud, and it was Krystal who pointed out its weakness.

Sargasso Space Zone

The Star Fox team headed to the Sargasso Hideout to find Pigma Dengar, who stole the Walker's core memory, something the team needed in order to fight the Aparoid Invasion. Krystal and Falco were tasked with destroying enemy fighter-craft outside the hideout. When Star Wolf arrived at their location, Fox rescued Krystal from several fighters. After Fox shoots down the rival team, its newest member, Panther Caroso, became overwhelmed by Krystal's beauty, so overwhelmed that he revealed Pigma's location to Krystal: planet Fichina.


On Fichina's frozen surface, Fox destroyed the shield generators hindering access to the planet's climate control center, while Krystal and Slippy backed him up later in the mission. Afterwards, Pigma made an appearance, and turned the main engineering tower into an Aparoid, threatening to destroy the climate control center, causing Krystal to express disgust at Pigma's actions. Fox destroyed it and saved Fichina.

Meteo Asteroid Belt

At the Meteo Asteroid Belt, Star Wolf seemed to have been destroyed, but Krystal's senses told her that they had abandoned ship. A horde of Aparoids appeared, a couple of them chasing Krystal later through the belt. Fox destroyed them, and Krystal rewarded him with a supply ring. After getting out of an abandoned base that they had infiltrated, Krystal noticed Pigma Dengar's ship drifting in space. Pigma and his base merged and became an Aparoid. The Core Memory was confiscated by the team, and Pigma was destroyed.


After sending the Core Memory to General Pepper, Krystal interrupted his briefing to the team by highlighting a distress signal coming from Sauria. Krystal and Fox went straight in to fight on foot, while Falco and Slippy took to the skies. During the mission, Krystal cleared an entire temple of Aparoids, and wondered about Tricky; She's likely heard of, or she knew Tricky prior to this event, it seems. After the Aparoids were defeated, Krystal and Fox stayed to look for Tricky, but he already found them just after they started. They were all happy to see each other. 

Corneria and Orbital Gate

Celebrations were brief, as the team received a distress call from Corneria, which had been overrun by the Aparoids. Krystal was tailed once again, but Fox also saved her again. She also reluctantly decided to ride the wing of Panther's Wolfen, but only as long as she could cover Fox. 

The entire Star Fox team, and even Star Wolf, fought Aparoids at the Orbital Gate to defend it so it could send them to Aparoid City while Beltino Toad finished work on a self-destruct program that will destroy the enemy. Krystal and Slippy were tailed, but manged to survive by maneuvering around the Gate until Fox could catch up and save them.

Aparoid Homeworld

After defending the gate from Aparoid missiles, Star Fox journeyed with the Cornerian Army to the Aparoid Homeworld to end the Invasion once and for all. At the surface of a base just above the planet's main underground tunnel, Krystal and Fox, backed up by air cover, destroyed the base's reproductive units, and eventually deactivated the shield protecting the planet's tunnel. It then activated a secondary shield before Star Fox could enter, forcing Peppy and ROB to crash the Great Fox into the shield, leaving Krystal and the team to believe that Peppy and ROB were killed. They eventually came to face with The Aparoid Queen herself, and after a long struggle, defeated her, causing Beltino's self-destruct program to work, destroying the queen and all Aparoids present. Fox and the team were able to make it out of the homeworld before it exploded. Seconds after Krystal mentioned Peppy and Star Wolf's sacrifices, Peppy and R.O.B. made contact, having survived the crash into the shield.

Anglar Blitz

In the events following the Aparoid Invasion, Fox had a growing concern for Krystal's safety and had her discharged from the team, which caused Krystal to adopt a bitter temperament. Heartbroken, she left and was not heard from again until the Anglar Army invaded Lylat.

How Krystal winds up after Command remains a mystery. In most of the game's endings, she reunites with Fox and once again rejoins the Star Fox team. However in some endings, she instead chooses to remain with Panther and the rest of Star Wolf or, in the default ending's case, she initially joins the Star Fox team, but then ends up leaving and joining Star Wolf later because of Panther. In one of the game's endings she has no choices she made in the past, and takes on a new life as a bounty hunter named Kursed. Alternatively, in another ending, She and Fox both leave the team to live a new life together.

Anglar Emperor Path

While she is a part of the Star Wolf team, it appears that she has begun a relationship with Panther. Fox learns this from Falco, who tells him that Krystal was with Star Wolf. Fox decides to track her down. He finds her at Sector Z, which is overrun with Anglars, but they defeat them all, with the help of Krystal. Fox apologizes, to which Krystal merely complies. She tells Fox that she and Star Wolf have defeated the base at Venom, but Anglar and the remains of his army escaped to the Asteroid Belt. She helps in the battle at the Asteroid Belt against Emperor Anglar. They take him down, along with his remaining forces, and are once again saviors of Lylat. Star Wolf sends a message, with Panther mentioning Krystal, how he is upset. Months later, Krystal leaves Fox to rejoin Star Wolf, to Fox's horror and Panther's joy.

Fox and Krystal Path

After Krystal disappeared, Fox and the team haven't heard from her. That is when Fox decides to track her down. He finds her on Katina, and urges her to join, but Krystal insults him, revealing that she is part of Star Wolf. Nonetheless, Fox helps defeat the Anglars on the Planet. After the battle, Fox doesn't give up, and tries to get her back, but Krystal is still acting nasty to him. She does consider this though, and says for him to apologize, then she'll think about it. Fox does, and despite Panthers protests, she joins. They meet up with the rest of the team, and to their surprise Krystal has changed. She tells Fox how to get to Venom. Andross had created a device to neutralize the Venom sea, and he hid it on Titania. They go there and defeat the bio-weapon guarding it, and head to Venom. On the way, Slippy is somehow able to get through to Krystal that Fox and her are meant to be together. At Venom, they kill the Anglar Emperor, and emerge victorious. Fox convinces Krystal to join, and that they are meant for each other. Team Star Fox is together again, with the new addition of Amanda, Slippy's fiancee.

Good-bye, Fox path

After team Star Fox defeated the Anglars, they go their separate ways. Fox finds Krystal on Sauria and she forgives him, they get married, and have a son named Marcus, who will be the future leader of Star Fox someday.

Star Wolf Returns path

After Fox finds Krystal on Katina, he tries to make her return, but to no avail. They rendezvous with Wolf, who found the device that neutralizes the Venomian sea. They head there, and defeat the Anglars. Star Wolf are recognized as heroes now, but people are calling Krystal a traitor. Krystal ultimately leaves Star Wolf, goes far away, becoming a bounty Hunter known as Kursed. On Kew, she and Fox cross paths, but he hardly recognizes her now.

Lucy and Krystal Path

Lucy Hare is on Corneria, trying to liberate the Planet from Anglars. There, she meets Krystal, Amanda, and Katt, who agree to help. They defeat the garrison, and the Splitter. They then get the news that Star Fox has defeated Emperor Anglar. Krystal is ready to forgive Fox, and when he and the team return to Corneria, she rejoins Star Fox, and forgives Fox.


  • Originally, when the game Star Fox Adventures was still being developed as Dinosaur Planet, Krystal had a much larger role in the game, and was revealed to be the adopted sister of the other protagonist, Sabre. This all changed, however, when it was decided that the game should become a Star Fox title.
  • The band for the necklace on Krystal's forehead seems to change in-between games. As in Adventures, it seems to be made of beads, and in Assault, it looks like a metal ring.
  • In most Star Fox Adventures artwork, Krystal is seen with Fox. This relates to an alternative outcome of the game as evident in unused voice acting.
    • More unused dialogue for Adventures has revealed that Krystal's distress calls heard at Moon Mountain Pass were also recorded in English, meaning these would have been used rather than Dino Talk. It is unknown why Rare used the Dino language recordings, as Fox had his working translator at the time and Dino Talk isn't Krystal's native language anyway.
  • Krystal is the only member of the Star Fox Team that does not have a known last name.
  • Despite playing an important role in Star Fox Adventures, Krystal is only playable once at the very beginning of the game, although she can be played as through Action Replay or GameShark as a model swap for Fox.
  • When Nintendo surveyed fans to see what new characters they hoped were in Brawl, Krystal was the top female character most hoped for. In spite of this, she didn't make a playable appearance. When polled again for who should become Smash Bros. Wii U and 3DS DLC, Krystal received fewer votes than before but was still found to be a consistently popular choice.
  • While Krystal does not make an appearance in Star Fox Zero, the game's director, Yusuke Hashimoto, has stated via Twitter that he would love to include her in a sequel if they ever got to make one.
