Vanish Attacks cost exactly one bar from your Ki Gauge Meter in order to be used, but it allows you character to teleport directly behind an opponent and perform a kick by pressing the Medium Attack and Heavy Attack Buttons at the same time. Vanish Attacks are extremely effective if your opponent likes to keep their characters stationary while battling; however, if you foe is moving around too much, Vanish Attacks are likely to completely miss the target.
