The A button on various Nintendo controllers. From left to right: Nintendo 64 and Nintendo GameCube controllers, the Wii remote and the Classic Controller

The A button (a button on the Classic Controller) is one of the main 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, and on both the Wii Remote and Classic Controller it is transparent with a white backing. 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 all four installments of Super Smash Bros., 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.
