Aero

Aero (エアロ), Aerora (エアロラ), and Aeroga (エアロガ) are spells which appear in Kingdom Hearts, Kingdom Hearts: Chain of Memories, Kingdom Hearts 358/2 Days, Kingdom Hearts Birth by Sleep, and Kingdom Hearts Re:coded. They utilize the "power of wind", and are associated with the Spirit and Gust materials. Aero spells form a miniature tornado that launches their target into the air, and can even be used to shield the user.

Kingdom Hearts
Sora and Donald Duck can obtain each type of Aero spell, but can only cast the most powerful version they possess. Tarzan's "Wind Armor" and Ariel's "Aero Potion" are their personal versions of Aero, and Peter Pan's "Storm's Eye" is his personal version of Aerora.

The spell creates a wind barrier around the user that lasts eighteen seconds, plus one extra second for each of the maximum MP the user possesses. This barrier decreases the damage taken by half, and the higher levels can damage enemies that touch the barrier, or deflect certain attacks.

Kingdom Hearts: Chain of Memories
As in Kingdom Hearts, Sora can cast the Aero spells. It causes wind to blow away surrounding enemies and inflict some damage on them. The Aero card can be used for many Sleights in Kingdom Hearts: Chain of Memories, all of which involve wind or flight.

As a magic card, Aero can also be used within the following sleights.

Kingdom Hearts 358/2 Days
In Kingdom Hearts 358/2 Days, Aero shoots a short range air projectile with some homing capabilities. Aerora shoots a zigzagging air blast that shoots the target into the air, making them take additional damage if hit before reaching the ground. Aeroga creates a whirlwind around the user that sucks in nearby enemies and damages them.

Kingdom Hearts Birth by Sleep
In Kingdom Hearts Birth by Sleep, the Aero spell conjures green storms of wind of varying sizes around the caster, which lifts up any enemies and damages them. The radius and power of the storm increases with the level of the spell.

Kingdom Hearts Re:coded
In Kingdom Hearts Re:coded, Aero magic is like a combination of the Aero spell from Kingdom Hearts 358/2 Days, and the Aero spells from Kingdom Hearts Birth by Sleep. It becomes a long range projectile with homing capabilities magic, similar to the Fire spells. But in addition, it will lift the enemy hit by the spell into the air.
