Stone, Kirby's down special move in all four Super Smash Bros. games.

The down special move (commonly referred to as down B) is a special move performed by pressing the special move button while holding the control stick downwards.

Down specials are the most varied of special moves and are often the character's most gimmicky attack - the majority of reflectors, absorbers, counterattacks, item-creating moves, and mid-match character transformations are down specials. They tend to involve minimal character movement.

Reverse down special

In Brawl, some characters' down special moves can be reversed by pushing the control stick or D-pad in the opposite direction a few frames after inputting the move. There is no animation for reversing a down special. Unlike other reverse specials, a reverse down special has a limited number of characters that can do it and fewer who will gain an advantage from it. The characters who can perform it are: Bowser, Yoshi, Pit, Ice Climbers, R.O.B., Pikachu, Marth, Ike, Ness, Lucas, Fox, Wolf, and Mr. Game and Watch. Since only Bowser, R.O.B., and Yoshi have a use for a reverse down special on the ground, some characters can use it in the air to gain a boost in the opposite direction and suprise opponents like Marth, Ike and Pikachu. The boost is most likely caused from a reverse down special having no animation and swaps the momentum around with the character.
