A "Final Smash" is a powerful special move in the Super Smash Bros. video game series. Each character has a unique Final Smash that can be activated when their special meter is filled. This move typically deals significant damage to opponents and can turn the tide of a match. To perform a Final Smash, players must first collect a Smash Ball, a floating item that appears during battles. Once a player breaks the Smash Ball, they can unleash their character's Final Smash by pressing the appropriate button combination. This mechanic adds excitement and strategy to gameplay.
