The Raikoukyaku (雷孔脚,literally Thunder Roaring Kick) is one of Reiji Oyama's special moves and has appeared in every one of his playable appearances. Reiji basically unleashes a non-stop barrage of lightning-fast kicks that hit the opponent several times. The speed of the attacks were determined by the strength button that was repeatedly tapped, and more hits can follow if the player continues tapping the button rapidly. In the first three games, the move could continue indefinitely as long as the player kept tapping the buttons. Since Matrimelee, however, the attacks only continue for a short time.
