Final Smash
A Final Smash (formerly called a Super Smash or Brawl Move by fans) is a special type of attack shown to debut in Super Smash Bros. Brawl. It is activated by touching the Smash Ball item, which then allows the user to activate an absurdly powerful "Final Smash" attack. Known FSs are a fire cyclone used by Mario, called the "Mario Finale", Link using the Triforce Slash, which involves rapidly slashing an opponent while trapping them between two triforce pieces, Kirby using his Chef ability to cook an enemy in a pot, Pikachu using Volt Tackle, which turns it into a large electric ball which you can control for a period of time, and Bowser transforming into Giga Bowser. [[Samus {SSBB}|Samus]] Final Smash has also been confirmed as a Transformation into [[Zero Suit Samus {SSBB|Zero Suit Samus]] all the Armor will come off and can be used as throwing Items.
It was speculated that the "Wario Waft" was a Final Smash, due to its nuclear weapon-sized power in the first trailer, but a recent update Smash Bros. site confirmed it as his Down-B (it seems the power displayed in the trailer was not actually the move's strength).
