Overview[edit]
In the default controller layouts of all installments in theSuper Smash Bros. series, the B button is used mostly for executingspecial moves. This includesneutral specials,side specials,up specials,down specials,Final Smashes and somecommand-input moves. Outside of gameplay, the B button is also the standard "back" button when navigating menus.
When playing with the Wii Remote held sideways, the1 button acts as a substitute for the B button, performing special moves, whereas the actual B button is used toshield the character with default controls. When using Joy-Con (R) as a single Joy-Con held horizontally, the B button will become the left button, acting like aY button and performing jumps, while the B button's menu and battle functionalities are given to theA button.
Super Smash Bros. Brawl introduced thecontrols menu option introduced in this game allows non-default actions to be mapped to the B button. This option has returned in every subsequentSmash release. While not directly related,Nintendo Switch hardware version 10.0.0 introduced the ability to map the functionality of any button to any other button from the console options menu, further diversifying how the B button can be used inUltimate.
