Up Smash Attack

Up smash, abbreviated "usmash," is a smash attack performed by any character by tapping the control stick upward and pressing A, or (in Melee's versus mode) by pressing up on the C-stick. The up smash can be charged by holding down the A button for up to two seconds in conjunction with the C-stick, resulting in higher damage and knockback.

Notable up smashes include:
 * Pikachu's up smash, which is often considered one of the best in the game because of its knockback and well-spaced hit box.
 * Sheik's up smash, which is the strongest in the game when sweetspotted.
 * Fox's up smash, which is very quick and a very good vertical kill move.
 * Lucas's up smash, which has a very high knock back and is very powerful, although slow.
 * Ivysaur's up smash, which is possibly the most powerful up smash in Brawl, very high power and knock back.
