Aero
Aero, Aerora, and Aeroga magic are attacks used by Sora, Donald, and other characters and enemies that utilize the element of Air. There is a fourth level, Aerogun; however, it is never obtained in terms of magic.
Sora learns Aero after defeating the Opposite Armor in Traverse Town.
By casting Aero, a barrier of wind temporarily surrounds Sora, making him more immune to most attacks. Aerora adds the effect of damaging any enemies that touch the barrier. A barrier cast by Aeroga may deflect certain attacks, and is more protective from boss attacks. However, it is important to note that Ursula and the Ice Titan actually become stronger if Sora uses any form of Aero.
Like Gravity, Aero was replaced by a different spell in Kingdom Hearts 2. Replacing it was Reflect.
