Down smash (abbreviated d-smash) or down smash attack (下スマッシュ攻撃, Down/lower/under smash attack) is a smash attack performed by any character by tapping the Control Stick downward and pressing A at the same time or by pressing down on the C-stick. In Super Smash Bros. Melee, the C-stick can not be used in one-player mode. It is generally an attack that hits low to the ground and hits on both sides of the character performing the attack.
Since Super Smash Bros. Melee, like all smash attacks it can be charged by holding down the A button for up to one second, resulting in higher damage and knockback. A typical attribute of a down smash is that they hit both the front and rear of the user, making them useful for coverage, and are generally the fastest smash attack for most characters. Most down smashes will attack the front and back in an alternating fashion, such as Mario's, where he does a spin to kick enemies, but a few can hit both areas at the same time, such as Fox's, where he does "the splits" to kick the area in front of and behind him in one motion, and a select few only hit in front of the user, as is the case with Lucas' and Mewtwo's. The disadvantage to most down smashes is that they tend to have lower knockback than either the character's up or forward smashes, and they have the least amount of flexibility out of all smash attacks in when they can be used, as they can only be performed while walking, standing, or crouching (a feat already shared with all other moves), while up smashes can be performed out of a run or jump (enabling it to be used out of shield with no delay), and forward smashes can be used during the first few frames of a dash or during a turn-around animation (in Smash 4 only).

Note: In Smash 64, down smashes are generally considered the least useful smash attacks of the three for every character due to their lack of versatility outside of tech-chases and roll punishes.
