Sleep is an attack effect that has appeared in every game in the Super Smash Bros. series. Grounded fighters hit by a sleep attack fall asleep for an amount of time based on the victim's total damage. If a fighter that is already asleep is hit by a sleep attack, its current sleep condition will not be increased in duration or reset.
Since enemies are immune to all status conditions, sleep attacks instead trip Smash Run enemies. In Super Smash Bros. Ultimate, the Support Spirit skill Slumber Immunity prevents the equipped fighter from being put to sleep by Spirit Battle slumber floors.
