A down tilt (abbreviated "d-tilt,"), officially called a strong down (下強攻撃, Down/lower/under strong attack), is a tilt performed by any character by holding the control stick lightly down and pressing the attack button while on the ground, or crouching ahead of time and pressing the attack button. It will instantly hit all surrounding characters, making it useful for spacing. It is also useful for a foe rolling around the player. It can also be performed by pressing Z while crouching. Only in Super Smash Bros. Melee and in Super Smash Bros. Brawl do some of these down tilts meteor smash an opponent. In Brawl and SSB4, many down tilts have the ability to make opponents prat fall/trip occasionally.
