KO
From SmashWiki, the Super Smash Bros. wiki
A KO, short for Knock-Out or Knock-Off, is the term used to describe the situation where a player is knocked back beyond the stage's blast lines by the opponent's actions. The KO'd player is sent to a revival platform to re-enter the match. The following may then happen depending on the type of match:
- In a Time match, the KO'd player will lose a point, while the player who made the KO gains a point.
- In a Stock match, the KO'd player loses a stock.
- In a Coin match, the KO'd player loses half their coins (if the number is odd, the "smaller half" is lost). SSBB prevents a player from losing more than 100 coins at once. The lost coinage will fly into play if the KO was made off the side.
- In the Subspace Emissary, the next character in the lineup is loaded and teleported into play without a revival platform. One stock is also lost.
If a player has no stock remaining, then they do not reappear. They are then either removed from play (multiplayer matches) or receive a Game Over (single player modes).
