The Boston Crab is a move exclusive to King I and King II. This move made its debut in Tekken 2. The player must delay the input of this move by a minimum of 10 frames, or the Double Arm Face Buster will be performed instead. Total damage for this move is 50, as King performs the Pile Driver (25 damage) first before turning his opponent over and snapping their legs.
This move is sometimes called the Boston Club in move lists due to a translation error (the words crab and club are the same in Japanese).
