Crouch Dash is a unique movement in Tekken. It is limited to a set of certain chracters, most notably the Mishima fighters. Generally, it can be performed by inputting either f, N, d, d/f (A DP motion type where in N stands for Neutral between f and d inputs), QCF or HCF. When used effectively in rapid succession, it can help the player to cover a lot of ground but a crouch dash is also a follow-up to unique attacks. The most notable of these attacks would be a wind god fist.
