Null

A null is a basic melee attack executed with the intention of stunning an opponent without a dash or stomp  attack. The most common null is performed with a single default walking attack, though it may also be performed with the second or third segment of a mash attack. Some players consider using backslash in this manner as a form of nulling. The purpose of a null is quickly and subtly attempt to stun a player without leaving the player vulnerable to an opposing counterpunch.
