From Zelda Wiki, the Zelda encyclopedia
A Final Smash is an attack that can be used in Super Smash Bros. Brawl. A Final Smash is an elaborate and powerful attack that can be used after grabbing an object called a Smash Ball, but can only be used once per Smash Ball. While performing a Final Smash, many characters gain auras around their body and the background darkens. Link and Toon Link use the Triforce Slash while Princess Zelda and her alter ego Sheik use the Light Arrows. Ganondorf transforms into his boar-like form seen in Twilight Princess.
