Zantetsuken

Zantetsuken is a powerful attack from Kingdom Hearts: Final Mix and Kingdom Hearts: Chain of Memories. In KH:CoM it is a sleight created by combining 3 attack cards with a total value of 0 or 27, and once used, renders a card useless and unreloadable for the remainder of the battle. In KH:FM it renders an attack useless, rather than a card.

Trivia

 * Zantetsuken's name and power originate from the special attack of the summon, Odin, from Final Fantasy.
