Editing KO

All characters have the same KO explosion, namely, a gigantic colorful blast that extends in the direction the victim was KO'd, in the color of the player's [[port]]: Player One's explosion is red, Player Two's is blue, [[CPU]]s are grey, and so on. Only two characters have slightly different KO explosions, {{SSB4|Mega Man}} and [[Luma]]: Mega Man will split up into orbs the color of his costume (alongside the normal explosion), like he does when he dies in the ''Mega Man'' series (they will sometimes not appear if many Mega Mans are KO'd at the same time), while Luma's explosion is smaller and creates colorful stars. A [[One-hit KO]] occurs when the target suffers a KO even when their damage is at 0%, while an [[Instant KO]] completely bypasses knockback and damage.

**Single-player: A [[Continue]] or a Game Over (the latter if the player doesn't have enough [[coins (collectable)|coins]] in ''[[Super Smash Bros. Melee]]'' and ''[[Super Smash Bros. Brawl]]'' or chooses not to continue).

*In a [[Coin Battle]], KO'd players lose half their [[Smash Coins and Bills|smash coins]], rounded down. [[Super Smash Bros. Brawl|''Brawl'']] prevents a player from losing more than 100 smash coins at once. The lost coinage flies into play if the KO was made off the side.

*In a [[Bonus (mode)|Bonus]] match (''[[Melee]]'' only), a KO will earn the player 500 [[bonus points|points]], while a fall will subtract 500 points.

Every fighter in ''Brawl'', ''Smash 4'' and ''Ultimate'' possesses two KO sounds, with the second being rarer and often a short phrase or line. However, there are a handful of characters with only one KO scream, which are:

*The {{SSBU|Mii Fighter}}s in ''Ultimate''  

[[StreetSmash]] gives Pac-Man a KO sound not heard normally. Notably, both of [[Ganondorf]]'s KO voice line in ''Brawl'' and ''SSB4'', female [[Corrin]]'s and female [[Inkling]]'s secondary KO voice lines are much longer than most other characters. ''Ultimate''{{'}}s [[Stamina Mode]] also uses one of these sounds for almost all characters except for {{SSBU|Mario}}, {{SSBU|Dr. Mario}}, {{SSBU|Joker}}, {{SSBU|Hero}}, {{SSBU|Banjo & Kazooie}}, {{SSBU|Terry}}, {{SSBU|Byleth}} and {{SSBU|Min Min}} who instead use their heavy knockback cries (in the case of Joker and Banjo & Kazooie, a unique voice clip plays instead). An [[instant KO]] from Hero's [[Command Selection|Kamikazee]] also always uses the primary KO voice clip. Another peculiarity specific to ''Ultimate'' is that, should a fighter be sent flying during their last stock and the current match end, their KO scream usually not play or play only very briefly.

While most characters simply emit pain sounds of various kinds when KO'd, from ''Brawl'' onward, a few such as [[Pit]] and [[Robin]] can speak phrases. All of these are used as secondary KO clips.
