In Kingdom Hearts II, Overdrive is an action ability exclusive to Auron. It costs 3 AP to equip and all of Sora's MP to use. The Limit begins with Bushido (がりゅう, Garyū?, lit. "Self-taught"), which causes Sora and Auron to stand back to back and slash enemies around them. Afterwards, two commands alternate between each other: Shooting Star (りゅうせい, Ryūsei?), in which the user spins around to attack enemies, and Banishing Blade (せいばつ, Seibatsu?, lit. "Conquest"), where the user leaps towards enemies and slices downwards with their weapon. Each of these two commands are spread out over the Attack and Reaction Command slots; Sora performs commands activated from the Attack slot while Auron executes commands triggered through the Reaction Commands. The finishing move is Spiral (じんぷう, Jinpū?, lit. "Gust"), where Sora and Auron spin their weapons rapidly to create a large tornado that draws enemies in before dealing heavy damage. Sora cannot move freely during this limit. The limit can be cancelled early through the Stop (やめる, Yameru?) command in the Limit slot.
Kingdom Hearts II
"Overdrive" stems from the name of the Limit Break system in Final Fantasy X, where Auron made his first appearance. Each segment of the Limit alludes in some way to one of Auron's four Overdrives. Bushido is the name which collectively refers to Auron's Overdrives, while the technique's Japanese name is a homophone to Garyū (牙龍?, lit. "Fang Dragon"), which is the Japanese name of Auron's Dragon Fang Overdrive. Shooting Star and Banishing Blade share their names with two of his Overdrives, and Spiral resembles and shares its Japanese name with his final Overdrive, Tornado.
