Hurricane Winder

Hurricane Blast (ハリケーンピリオド), known as "Hurricane Period" in Kingdom Hearts HD 2.5 ReMIX, is an ability that appears in Kingdom Hearts Final Mix and Kingdom Hearts II Final Mix. It allows Sora to spin-slash with the Keyblade 1080 degrees vertically in rapid moonsaults.

Mechanics
In Kingdom Hearts Final Mix, Hurricane Blast is a combat ability that provides Sora with an air combo finisher. It costs 2 to equip. It is meant as an strong ability that can help damage enemies on a vertical alignment of Sora during an air combo, due to his default air combo finisher flying over them quite often. Sora will also drop down to the ground at some point during his moonsaulting period.

In Kingdom Hearts II Final Mix, Hurricane Period is an action ability that provides Sora with an aerial finishing move. The ability now has light effects and Sora now stays in the air during this attack and flies forward a bit.

Kingdom Hearts Final Mix

 * Sora learns Hurricane Blast at level 27 with the Dream Sword, 51 with the Dream Shield, and 18 with the Dream Rod.

Kingdom Hearts II Final Mix

 * Limit Form has Hurricane Period as a default ability.
