Krystal

Krystal is the false protagonist of Star Fox Adventures, and one of the game's main goals is to free her from imprisonment.

She was originally going to be a playable character in Dinosaur Planet and would be a feline and relatively younger.

A World in Distress
Krystal first appears after she hears that Dinosaur Planet is in distress, and sets out to save it. She is fired upon by General Scales' flagship, and after overcoming some obstacles, and accidentally losing her staff, Krystal damages the ship enough to get onboard and speak to the ship's captain. General Scales confronts her and throws her overboard where a denizen of Dinosaur Planet, the same one she used to fight the big ship with, saves her from falling to her death and she makes her way to the Krazoa Palace.

Test of Observation
Krystal hears from an injured EarthWalker that the Krazoa Spirits and Krazoa Palace were in danger. Shortly afterward, she encounters her first Krazoa, who challenges her to one of many tests. This test was all about finding which vase the Krazoa was hiding in. After the challange was over with, she got possessed by the spirit and released it into its respective section of the palace.

"Krystalization"
While she was releasing the spirit, an unknown foe trapped her inside of a giant crystal, which was elevated to the rooftops. Sometime afterward, Fox McCloud gets a message from a Krazoa-like entity that Krystal needs his help, and sometime after Fox arrived at the Krazoa Palace, he encounters Krystal for the first time. He is mesmerized by her beauty upon first seeing her until Slippy snaps him out of it, much to Fox's chagrin.

Freedom and Recruitment
It took awhile, but finally, after all seven spirits are brought to the palace, Krystal is freed, but at a great price; Fox can't use her staff anymore, as it wasn't his to begin with, and the wicked Andross was revived. Krystal tried to fire fire from her staff thinnking Andross would be hurt, but he escaped unscathed. Fox then leaves her behind to Andross in space with his Arwing.

After the final battle was over, Krystal managed to make it to the Great Fox and become its first female member, much to Fox's great delight.
