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, Kingdom Hearts Birth by Sleep, and Kingdom Hearts Re:coded. 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.
