Dark Aura

Dark Aura (ダークオーラ) is an ability which appears in Kingdom Hearts: Chain of Memories and Kingdom Hearts II. It has two forms. The first consists of Riku rapidly opening portals of darkness and rushing out of them at the opponent with his blade, then slamming the ground to summon a column of light that confuses the enemy. The second, used only in Kingdom Hearts II, consists of Riku firing orbs of darkness which stop the enemy's movement. In Kingdom Hearts II, it requires 2 AP to equip and 10 MP to use.
