Gale is a material used in synthesis in Kingdom Hearts. It is a frozen crystalized form of howling winds, hence its name; the original Japanese name, "Blustery Winds", also reflects its description. A rare drop, it can only be found at the end of the game, when the End of the World is unlocked and the Heartless that drop it are made available.
Because of its late accessiblity, it is only used to create items on the last two lists in the Moogle shop. Gale's most important use, however, is in the creation of Sora's Ultima Weapon.
