Stamina (stat)
From SmashWiki, the Super Smash Bros. wiki
At the start of a match, each Pokémon has 120 points of stamina. When a Pokémon is in battle, its stamina drops by one point every second. (This equates to about 2 minutes of stamina.) The Pokémon also loses a point of stamina for every attack it attempts. Once a Pokémon's stamina drops to 36 (that is, 30% of its maximum), its standing animation switches (see image) to signal fatigue. When the Pokémon's stamina reaches 0, its attacks drop in damage and knockback. Pokémon regain 2 points of stamina per second when not being used, and all Pokémon are restored to 120 (the maximum) when any one of them is KO'd.
