B button

"B" redirects here. For the move type for which the B button is used for, see Special move.

The B button on various controllers. From left to right: Nintendo 64 controller, GameCube controller, Wii Remote, Classic Controller, Nintendo 3DS, Wii U GamePad.

The B button is either the large, green button on the Nintendo 64 controller, the small, red button on the Nintendo GameCube controller, the rectangular trigger button on the back of the Wii remote, the clear button towards the bottom right of the Classic Controller, the varyingly-colored circular button on the Wii U GamePad, Wii U Pro Controller and Nintendo 3DS, or the bottom dark gray face button on the Nintendo Switch's right Joy-Con and Pro Controller. It is used, by themselves or in conjunction with any direction on the control stick, to activate special moves in Super Smash Bros., Super Smash Bros Melee, Super Smash Bros. 4 and Super Smash Bros. Ultimate. In Super Smash Bros. Brawl, controls and control settings can be changed. By default, though, when using the Nunchuk, Classic, or GameCube control schemes, the B button activates special moves as well. With the Wii Remote alone though, the 1 Button acts as its B button, performing special moves, whereas the actual B button is used to shield the character with default controls. It also appears on the Wii U GamePad and Nintendo 3DS for both installations of Super Smash Bros. 4. When using Joy-Con (R) as a single Joy-Con held horizontally, the B button will become the left button, acting like a Y button and performing jumps.
