Frystal

Frystal is the het ship between Fox McCloud and Krystal from the Star Fox fandom.

Star Fox Adventures
The first meeting of Fox and Krystal was instigated due to a growing crisis on the planet Sauria. Finding a distress signal on the planet, Krystal arrived first and attempted to find the source. The search eventually took her to the Krazoa Palace and brought her to begin helping the spirits within as their survival was paramount to keeping the planet alive. However, after getting only the first Krazoa back to the palace, Krystal ends up trapped in a crystal due to an unknown assailant. The continually deteriorating situation on Sauria eventually had the Star Fox team hired to deal with it, with Fox heading to the surface on his own.

Nearly as soon as he landed, Fox finds Krystal's staff - which she accidentally dropped on her way to the palace. From her crystalline prison, she sent Fox a telepathic message on how to use it. Fox's journey eventually led him to Moon Mountain Pass, where he begins hearing Krystal's telepathic echoes crying for help. The Krazoa that Krystal saved earlier informs Fox that the only way to save her is to finish her mission. Fox initially refuses to do so as he doesn't have the time to save a stranger when Sauria is in danger, but Krystal's telepathic cries finally convince him to do it. He eventually rescues a Krazoa and is brought to the Palace. It's at the top of it where Fox finally meets the trapped Krystal in person. He's immediately smitten by her beauty, so much so that Peppy has to contact him on his communicator to remind him about his mission. With new determination to save Krystal, Fox leaves to continue on.

Fox continued across Sauria to find the rest of the Krazoa spirits and bring them back to the palace. Upon returning the last one, however, Fox realizes that something was wrong as it looked like Krystal was beginning to struggle in pain before the crystal she was contained in shatters and she begins to plummet to her death. Luckily, Fox manages to grab her and bring her back to safety. Before anything chivalrous between either, a statue head that the Krazoa possessed - one that proclaimed to be a "Mighty Krazoa God" - begins flying into space. Krystal roughly takes back her staff from Fox - which he's annoyed by - and begins futilely firing at it while Fox runs back to his Arwing and pursues it into orbit. Fox eventually deals with the "god" - in reality a revived Andross - and saves Sauria. In the aftermath, Krystal sent a message to Fox thanking him for what he's done and apologizing that they didn't get more of a chance to talk. As the message is playing, however, Krystal reveals she docked onboard the Great Fox to personally thank him. Fox stutters at Krystal being there, which both Slippy and ROB64 rib him on.

Star Fox: Assault
About a year following the events on Sauria, Krystal became a member of the Star Fox team - using her telepathic abilities as well as becoming their fourth pilot following Peppy's retirement from the frontlines. The team is eventually hired by the Cornerian Defense Force to assist in dealing with a resurgent force led by Andrew Oikonny - Andross' nephew and a former member of Star Fox's rivals Star Wolf - on the planet Fortuna. The team manages to break through Oikonny's defensive line - with Fox and Krystal taking the right side of the line - and pursue him to Fortuna's surface before fighting him. This is interrupted when a mysterious creature arrives and destroys Oikonny's ship before firing at Krystal and nearly hitting her, causing Fox to order the team to destroy it. In the aftermath, the team learn the creature was an Aparoid, and it's appearance means they are on the move.

Star Fox is then sent to the CDF's outpost on Katina to assist in quelling the Aparoid invasion there. Krystal expresses fear when Fox suggests going on foot alone, but he points out that he wants her and the others covering him in the air. During the fight, Krystal ends up tailed by some flying Aparoids, but Fox is able to shoot them down using a Landmaster. Krystal is also the one to find the weak point on the massive Aparoid walker that arrives, allowing Fox to take it out. As Fox goes to take its core memory, however, Pigma Dengar arrives and takes it before departing. This prompts Star Fox to pursue him to get the memory (which contains the location of the Aparoid homeworld). The search takes them to both the Sargasso Space Zone and the CDF's climate base on Fichina - both of which resulting in fights where Krystal covers for Fox while he's on foot - before finally finding Pigma in the Meteo Asteroid Belt. Searching the belt, the team finds ans Aparoid swarm in waiting for them, some of which pursue Krystal but she's promptly saved by Fox. After passing through an in-construction base, the find an Aparoid-infected Pigma merged with some machinery before destroying him and finally getting the Core Memory back.

As Star Fox is getting ready to attack the Aparoid homeworld alongside the CDF, Krystal senses the Aparoids are attacking Sauria. Upon examining the situation, they find hatchers on the surface that are making more Aparoids. Fox decides he and Krystal will head down to the surface to deal with them, something Krystal is glad for because they finally get a mission together. The two manage to clear out the temples of Aparoids and eventually destroy the hatchers. As Fox and Krystal confirm that the Aparoids have been taken care of, they are surprised by the appearance of an adult Prince Tricky - Fox's guide during his first time on the planet - as he came to thank them for saving Sauria. When Fox affirms to Tricky that he's the leader now, Tricky agrees to keep the peace so that he and Krystal can come back for their honeymoon. Upon realizing what Tricky just said, Fox tries to deny that he and Krystal are together but his flustered attitude - and Krystal throwing doubt in - leaves him no other recourse than to drop the subject. After the events on Sauria, Fox, Krystal, and continue the conflict with the Aparoids before finally defeating them.

Star Fox Command
Some time following the Aparoid crisis, Star Fox had disbanded with most of the members having gone off to do other things. While the team was still together, Fox started to worry for Krystal's safety on missions to a rather unhealthy degree. Eventually, his worry got to the point where he forcefully sidelined Krystal, and ultimately asked her off the team, with no one having seen her since. However, Lylat faced a new threat in the Anglar Empire and Fox had to bring the team back together to defeat them. The way this occurs varies and leads to a number of different outcomes.

Path 1: Fox and Krystal= Meeting with Slippy's father Beltino, Fox learns that the Anglars had set up a base in the seas of Venom, which are too dangerous to enter normally. Falco, knowing Fox will want to go deal with the base, suggests patching up things with Krystal to get some more help for the assault. With encouragement from Slippy and Beltino, Fox relents and goes to where Falco last heard she was - Katina. At Katina, Fox manages to find Krystal and asks her to come back, but finds her not only cold to him - but also now a member of Star Wolf. In an effort to get Krystal back, Fox assists Star Wolf in dealing with the Anglar forces on Katina.

Following the battle, Fox again tries to get Krystal to return to him, to the point of profusely apologizing to her for how he treated her. While not completely forgiving Fox, Krystal does ultimately go with him and leads him to Titania, where a terraforming device built by Andross that would allow the team to enter Venom's seas was buried. After getting the device, Slippy confronts Krystal about her hostile attitude towards Fox, reminding her that he saved her and the number of times she risked her life for him, before finally telling her about his fiancée Amanda - which finally convinces Krystal to make amends. However, at Venom, Fox bitterly tells Krystal that her part is done and she can go back to Star Wolf, which shocks the rest of the team. Krystal, however, continues to help the others, eventually working with them to defeat the Anglar Emperor. Following the battle, Fox and Krystal finally reconcile and the latter returns to the Star Fox team.

After the Star Fox team beats Oikonny (who had allied with the Anglar) at Fichina, Lucy Hare - Peppy's daughter - reveals to Fox that she's talked with Krystal. She noted that Krystal's been quite lonely since she and Fox broke up before asking him why he's not trying to find her. Fox points out that she was in more danger at his side, which upsets Lucy because it makes him look like he picked Star Fox over Krystal - an accusation that Fox remorsefully accepts. After Lucy manages to convince her father to come back into action, the reunited Star Fox team find Andross' terraforming device - which will allow them to face the Anglar forces in Venom's seas. After getting it, Fox reveals that once the conflict is over he's going to find Krystal and end his life as a mercenary as he wants Krystal to be happy. After the team defeats the Anglar Emperor at Venom, ROB reveals that Krystal is on Sauria, which Fox acts on. In the years after Fox and Krystal reunite, the two live a quiet life, eventually marrying and having a son.
 * -|Path 2: Good-bye, Fox=

After the Star Fox team beats Oikonny (who had allied with the Anglar) at Fichina, Lucy Hare - Peppy's daughter - reveals to Fox that she's talked with Krystal. She noted that Krystal's been quite lonely since she and Fox broke up before asking him why he's not trying to find her. Fox points out that she was in more danger at his side, which upsets Lucy because it makes him look like he picked Star Fox over Krystal - an accusation that Fox remorsefully accepts. Later, when the team deal with an Anglar force at Aquas, Falco arrives and tells them that Krystal was now a member of Star Wolf, much to Fox's shock and disappointment. Before anymore discussion is held, they learn that Star Wolf had already dealt with the Anglar base at Venom and the Emperor is now rallying his forces at Sector Z.
 * -|Path 3: The Anglar Emperor=

At Sector Z, Star Fox are met by Krystal retreating from the Anglar forces and asking them for help. Fox agrees to help her while also noting he's glad to see her again but still heartbroken that she went to Star Wolf. After Krystal explains why she went to them, and how they scattered following the destruction of the Venom base, Fox tells the team that they'll find Star Wolf once the Emperor is dealt with. Just as the Emperor is defeated, Star Wolf arrives but disparage that they lost the prize, with Panther especially upset that Krystal is seemingly with Fox again. Things were good for the next few months until Krystal suddenly quits the team and returns to Star Wolf - much to Fox's heartbroken confusion.

Star Wolf Returns: While the rest Star Wolf basks in the glory of defeating the Anglars, Krystal is forced to deal with the public thinkng of her as a traitor to Star Fox. It gets to the point where she leaves Star Wolf and rebrands herself as bounty hunter named Kursed. A few years later, Fox had an encounter with Kursed on Kew but couldn't recognize her.
 * -|Other Paths=

Lucy and Krystal: During a celebration held by to celebrate the end of the Anglar menace, Fox and Krystal sneak off to talk with each other. There, they reconcile and Krystal agrees to return to Star Fox.

The Curse of Pigma: After Fox and Falco were sidetracked, they see that Star Wolf had ended the threat of the Anglar Empire and were being hailed as heroes. During that celebration, Krystal - now a member of Star Wolf - reveals to the public what Fox did to her. After hearing that, Fox set course to Papetoon so he can drown away his sorrow at Star Wolf having taken everything from him.

Children
