A '''KO''' ({{ja|撃墜|Gekitsui}}, ''Shoot down'' or {{ja|バースト|Bāsuto}}, ''Burst''), short for '''knock-out''' or '''knock-off''', commonly known as a '''death''' or a '''kill''' or even a '''finishing blow''' by [[Stamina Mode]], occurs when a player is [[knockback|launched]] beyond the [[stage]]'s [[blast line]]s by the opponent's actions used in the ''[[Super Smash Bros.]]'' series. The KO'd player is sent to a [[revival platform]] to re-enter the match. Losing all [[HP]] in [[Stamina Mode]] results in a KO without crossing a blast line, and some attacks and hazards can cause [[instant KO]]s without the target crossing the blast line or being launched at all.

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. However, two characters have use slightly different graphics. [[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). [[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.

Once KO'd, the following may then happen depending on the type of match:
*In a [[Time]] match, the KO'd player loses a point, while the player who made the KO gains a point.
**In ''[[Super Smash Bros.]]'' and ''[[Super Smash Bros. Ultimate]]'', the score indicators are present in both Time and Stock matches but are meaningless in the latter. In other games, the indicators are absent for Stock matches.
*In a [[Stock]] match, the KO'd player loses a stock. If players lose all their stocks, they will receive the following:
**Single-player: A [[Continue]] or a Game Over (the latter if the player doesn't have enough {{b|coin|collectable}}s in ''[[Super Smash Bros. Melee]]'' and ''[[Super Smash Bros. Brawl]]'' or chooses not to continue).
**Multiplayer: Removal from the rest of the match. In a team match, the player can [[Share Stock|"borrow" a stock from an ally]].
*In a [[Coin Battle]], KO'd players lose half their [[Smash Coins and Bills|smash coins]], rounded down. ''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 {{b|Bonus|mode}} match (''Melee'' only), a KO will earn the player 500 [[bonus points|points]], while a fall will subtract 500 points.
*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.
**Characters can also be KO'd in the Subspace Emissary if they are [[crush]]ed by moving walls, ceilings, or floors.

==KO property==
In ''Super Smash Bros.'' and ''Melee'', each character has a "KO property" which starts out empty. When characters are hit by any attack (be it a physical attack, a projectile, an item, etc.), their KO property is set to match whoever made the hit. Stage elements do not change the KO property, except for [[Barrel Cannon|cannons]], which reset it. The KO property is reset once a character lands on the ground and is no longer moving as a result of the attack's [[knockback]]. When the character is KO'd, the KO goes to whoever matches the KO property. If the property is empty, the KO counts as a [[self-destruct]]. In simple terms, it goes to whoever made the last hit. Any statistical data related to the KO property is recorded at the end of a game and is made viewable in the [[Records]] menu, which is possible in all games in the series.

However, this format was altered for ''Super Smash Bros. Brawl''. A character's KO property is now only reset 3 minutes after landing on the ground. This essentially means that a character must refrain from being hit for 3 minutes for a self-destruct to actually count as such; otherwise, a self-destruct will be credited as another player's KO. While this was possibly implemented to avoid griefing in online matches (by self-destructing simply to deprive other players of points), its main effect is preventing players from giving themselves illegitimate data for their records, as the previous exploit of players jumping off the edge a few seconds after successfully [[recover]]ing to register a self-destruct is effectively removed.

There are exceptions to this new rule, particularly during most [[Final Smash]]es. If a player jumps off the stage during a Final Smash such as {{b|Zero Laser|Samus}}, then, unless someone else hit them before landing, it will count towards the user of the Final Smash, instead of the last one to hit them (Samus in this case). Moreover, getting KO'd during the usage of certain Final Smashes such as {{b|Giga Bowser|Final Smash}} will result in a self-destruct instead of a KO, even if players have been damaged by opponents previously. Characters with invincibility from a {{b|Starman|item}} will also self-destruct instead of being KO'd.

''[[Super Smash Bros. 4]]'' retains the ''Brawl'' system, but with one notable change: in matches of two players, any self-destructs are also credited as KOs for the opponent. For example, if a player has been KO'd once and has one self-destruct, the opponent will be credited with two KOs. This change only affects KO-based statistics; it has no real effect on who wins the match. ''Ultimate'' utilizes an identical system, but with an additional rule that [[grab]]s now count towards the KO property, which was not the case in previous entries.

==KO sounds==
In addition to the colorful KO blast, every fighter makes a loud, distinct vocal sound upon being KO'd, though there are some exceptions who are silent due to lacking voice lines. Throughout the series, these exceptions are:
*[[Piranha Plant]]
*[[Steve]]
*[[Samus]] (''Brawl'' onwards; has a Star KO sound effect)
*[[Dark Samus]] (has a Star KO sound effect)
*[[Mr. Game & Watch]] (not in ''Melee'' or ''Ultimate''; Star KO sound effect is still present in ''Brawl'' and ''SSB4'')
*[[Olimar]]
*[[Villager]]
*[[Isabelle]]
*[[Little Mac]] (when using Wire-Frame Mac costumes)
*[[Duck Hunt]] (has a Star KO sound effect)
*[[Mega Man]] (excluding "8-bit explosion" sound effects)
*[[Pac-Man]]
*[[Mii Fighter]]s (not in ''Ultimate'' if voice clips are set).

Every fighter in ''Brawl'', ''Smash 4'' and ''Ultimate'' possesses two KO sounds, with the second being rarer and often a short phrase or line (the second KO voice clip has a 1 in 6 chance of playing). However, there are a handful of characters with only one KO scream, which are:
*[[Jigglypuff]] (due to the English voice being recycled from ''Smash 64'' and ''Melee'' in all games; the German and French voice clips also follow this trait, but has two in Japanese)
*[[Mewtwo]] (as a possible callback to ''Melee'')
*[[Roy]] (as a possible callback to ''Melee'')
*{{SSBU|Mr. Game & Watch}} in ''Ultimate''
*The {{SSBU|Mii Fighter}}s with voice clips set in ''Ultimate'' 
*[[Bayonetta]]
*[[Ridley]]
*[[Sephiroth]]

[[StreetSmash]] gives Pac-Man a KO sound not heard normally: the original "lose a life" sound from ''Pac-Man''. 

Notably, both of [[Ganondorf]]'s KO voice lines 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|Hero}}, {{SSBU|Terry}}, {{SSBU|Byleth}}, {{SSBU|Min Min}}, {{SSBU|Sephiroth}}, {{SSBU|Pyra}}, {{SSBU|Mythra}}, {{SSBU|Kazuya}}, and {{SSBU|Sora}} who instead use their heavy knockback cries, and {{SSBU|Joker}} and {{SSBU|Banjo & Kazooie}}, who use a unique voice clip. 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 ends, their KO scream usually not play or play only very briefly.

===List of unique KO lines===
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, except for Zelda, whose main KO line is spoken in Japanese.

==Trivia==
*In ''Super Smash Bros.'', the sound effect that plays for the blast KO uses the same "[[ping]]!" sound effect from certain moves or items, albeit slowed down significantly.
*In ''SSB4'' and ''Ultimate'', should a fighter be sent flying when extremely damaged (such as at 999%), their KO scream may not play and will be replaced by one of the fighter's "hurt" voice lines or nothing at all. This happens more frequently if the fighter is [[frozen]], or if a character is hit right by a blast line.
*In ''Ultimate'', while the [[Screen KO]] uses the Blast KO effect at the end of the animation, Mega Man will not split up into orbs.
