The A button (a button on the Classic Controller) is one of the buttons on each controller where it is present. On the Nintendo 64 controller it is blue, on the Nintendo GameCube controller it is an aqua-green, on both the Wii Remote and Classic Controller it is transparent with a white backing, and on both the Nintendo Switch Joy-Con and Pro Controller it is dark gray. The colour of the button on the Wii U GamePad, Wii U Pro Controller and Nintendo 3DS depends on the colour of the controller or console. In the default controller layouts of all installments in the Super Smash Bros. series, the A button is used mostly for executing standard attacks. When playing with the Wii Remote held sideways, however, the 2 button acts as its A button, performing smash attacks (when pressed with the D-pad or the 1 button) and confirming selections on menus, whereas the actual A button is used for taunts. When using Joy-Con (R) as a single Joy-Con held horizontally, the A button will become the bottom button, acting like a B button and performing special attacks.
