Fire

Fire, Fira, and Firaga magic are attacks used by Sora, Donald, and other characters and enemies that utilize the element of Fire. In Kingdom Hearts, using Fire magic will make Sora shoot a fireball straight forward from the tip of his Keyblade and it has an MP cost of 1 Charge Gauge unit. The fireball has slight homing properties, meaning it can arch in any direction, however, the arch is rather large. In Kingdom Hearts II, Fire acts as a shield that forms around Sora and attacks any enemies that comes in contact with it; useful until acquiring the Reflect spell.

Fire magic will be usable again in Kingdom Hearts: Birth by Sleep. It seems it can be used as both a fireball and a shield.
