Whyt is Rydia's Eidolon, and appears after Mist is destroyed. Whyt is a Whytkin, a "larval" Eidolon that has yet to mature to gather individual abilities. Like his parents, Whyt stays a Whytkin so that they can create new baby Eidolons. Despite this, Whyt has hidden potential that can increase his power greatly.
The player can design his face using the stylus. The customized face is saved automatically onto the DS Game Card, along with the high scores of the mini-games, so when a New Game is started, that face is the one the player sees. There are also costumes Whyt can obtain. New costumes are earned from the minigames. A Goblin costume is obtained when the player beats the game once, then beats it again using New Game+. A Zeromus costume is obtained when the player completes the entire Bestiary.
When Whyt is summoned, he replaces Rydia in battle and acts automatically, based on the abilities the player assigns it prior to battle. It has infinite MP and will act thrice before dismissing itself.
Whyt's stats can be increased by playing a selection of five minigames available from the Fat Chocobo. Whenever a new high score is added to the player's top three, Whyt will get an increase in stats. The minigames require the use of a stylus to the DS's touchscreen.
After gaining so many points, the player is rewarded with a certain item:
|1,000-6,999||Potion, Antidote, Eyedrops, Echo Herb, Golden Needle|
|7,000-9,998||Ether, Hi-Potion, Phoenix Down, Unicorn Horn, Cottage|
|9,999||Remedy, Hi-Ether, X-Potion|
There are five minigames total. Each minigame applies to one of the five final characters: Rydia, Cecil, Kain, Rosa, and Edge, and they all boost one of Whyt's five stats. Any stat boosts earned will carry over to any other game file. If Whyt has received the max stat boost from a score of 9,999, the same stat boost applies when a new game is started. When Whyt gains 9,999 in the minigame, it gains a special costume similar to the that of one of the five characters. All minigames can be ended immediately when the player hits .
Rydia's Mathemagic MinuteEdit
The player has 60 seconds to take four whole numbers equal to or below ten and add, subtract, multiply, or divide them until only ten remains. The numbers must be dragged into two squares, and the mathematical operation can be changed using the four symbols below. The number created by this operation is added to the list, until only one number remains. If the final number is ten, points are given.
The player can pass on difficult numbers, and undo mistakes. The more times the player makes ten without passing or getting the wrong number, the more points the player gets for each ten made. A useful trick is the close the DS up, thus pausing the game allowing the player to do the math without losing any time. Whyt's Intelligence stat is boosted by this minigame.
Rosa's Measured MeditationsEdit
While Rosa is praying, the player must place the stylus down on the touch screen and hold it there for as close to the indicated time as possible. The closer the player removes his or her stylus from the screen to the actual time, the more points that will be received.
If they remove the stylus from within two seconds, they will get 100 points, but if they remove it from within 1 second, they will get 300 points. Removing the stylus at exactly the right time will get 4,000 points. There is a clock in the minigame, but this is a trick. Its movements are not based upon real time. Using a stopwatch works better. This minigame increases Whyt's Spirit stat.
Cecil's Goblin GauntletEdit
Cecil is fighting Goblins who are rushing at him from all sides. To kill the Goblins, the player must tap them with the stylus. There are several different types of Goblin each with different colors and can take more hits. Green and Orange take one hit, Purple takes three, and the Giant Green Goblin takes ten. Whenever a Goblin is hit it is stunned allowing the player to hit it again. The more hits a Goblins takes to be defeated, the more points it gives.
Green gives 30 points, Red gives 50, Purple 80, and Giant Green gives 200. Cecil has two hearts that are his health. If he is hit twice, the game is over. The only way to save points is to hit the "Escape?" next to Whyt at the bottom right of the screen. Touching the sword icons will hit every Goblin on the screen. Bombs will instantly kill all the Goblins. As the game goes on the Goblins come in faster and in greater numbers. It is helpful to add a friend to kill more Goblins faster. This minigame increases Whyt's Strength.
Kain's High Jump HijinksEdit
Kain is about to do a Jump into the air. The player must rotate the stylus around him as fast as possible for ten seconds so that his Jump is as high as possible. While flying up, birds attack. Tapping them with the stylus will cause Whyt to incinerate them.
All can be defeated with a single tap of the stylus. As Kain flies up higher and higher, the birds will come in faster. The higher Kain can Jump, the more points rewarded. The game ends as soon as Kain is hit by a bird. This minigame increases Whyt's Stamina.
Edge's Ninja Blade GladeEdit
Edge is at the bottom of the screen throwing shuriken at enemies that appear at the top. Tapping the enemies with the stylus will cause Edge to throw a shuriken at them, though he can only throw a few at a time. If the enemy lives too long, it will fire an attack at Edge. Throwing a shuriken at the attack can cause it to be deflected, but this is based on luck.
Holding the stylus down on Edge will make him use Ninjutsu and hide, thus avoiding the enemy attack. Edge has three hits, and the game lasts sixty seconds. There are three kinds of enemies that appear: Death Flowers that take one hit and give 150 points, Treants that take two hits and give 300 points, and a Giant Malboro that takes twenty hits and gives 3,000 points. The Giant Malboro will only appear once after thirty seconds have passed. This minigame increases Whyt's Speed stat.
Users in Square Enix Members Virtual World community can make their character appear as one of several looks for Whyt.
Whyt's Japanese name is Pōchika. Poch'ka is the Russian word for "flower bud". This could be a reference to Whyt's status as a "base" for all Eidolons. The English name Whyt may be derived from the word "whit" (meaning the smallest part of something) for the same reason, as well as to reflect the creature's color (white).
