The up special move (commonly referred to as Up-B) is a special move that a character may perform that involves by pressing the designated button while holding the up key. It is usually used for recovery purposes as it usually launches the character upwards, but there are few exceptions to this, such as Jigglypuff's move Sing. Super Smash Flash has an equivalent attack, refered as the up attack, who is infamously known for it finshing properties when attacking incoming airborne opponents, launching them to the sides of the stage.
