Firestorm (ファイアブレイザー, Faia Bureizā?, lit. "Fire Blazer") is a Command Style that can be used by Terra, Ventus, and Aqua in Kingdom Hearts Birth by Sleep. It is activated by using Fire-related Deck Commands or the Bueno Volcano ice cream.
While using Firestorm, Terra, Ventus, and Aqua's attacks become faster and deal fire damage; their standard four-hit combo deals 125% damage, while the fire projectile on the third hit deals 75% damage. The combo finisher is a burst of fire surging from the user's body that deals 200% damage. The finish command deals 250% damage and consists of the user jumping in the air, charging energy, and hurling a fireball that erupts into multiple pillars of flame.
