Zantetsuken

Zantetsuken (ザンテツケン) is an ability which appears in Kingdom Hearts Final Mix, Kingdom Hearts: Chain of Memories, Kingdom Hearts II Final Mix, and "Kingdom Hearts Birth by Sleep". It consists of holding the Keyblade tip-backwards, then performing a single powerful slash through the opponent's body so quickly that the cut doesn't appear until after the technique is finished. It is usually a ground combo finisher, and can defeat minor enemies in a single hit. In Kingdom Hearts Final Mix it requires 2 AP to equip, while in Kingdom Hearts II Final Mix it is only available while using Limit Form. In Kingdom Hearts: Chain of Memories, the damage it inflicts is sharply reduced, and instead it is able to break the opponent's card and render it unreloadable.
