Editing Instant KO

An '''instant KO''' is a type of [[KO]] which occurs instantaneously and in-place, without the fighter passing a [[blast line]] or being [[knockback|launched]] at all. A character suffering an instant KO will disappear into a colorful [[Obliviate|starburst explosion]], while letting out one of their blast KO cries, and then (if they have any [[stock|stocks]] left) [[respawn]] as normal. Instant KOs were introduced as [[stage hazard]]s in ''[[Super Smash Bros. Brawl]]'', and a greater variety of attacks and conditions causing instant KOs were added in ''[[Super Smash Bros. 4]]'' and ''[[Super Smash Bros. Ultimate]]'', the latter game introducing instant variations of [[Screen KO]]s, [[Blast zone]] and [[Star KO]]s. Several instant KOs require the opponent to be at a certain [[damage]] threshold in order to be instantly KO'd; otherwise they will be launched as usual.

*Several levels in [[The Subspace Emissary]] feature moving walls, blocks, elevators, and similar solid platforms. If they are caught between two of these objects as they collide together, the player will be [[crush]]ed and instantly KO'd.  

* If {{SSB4|Bayonetta}}'s [[Infernal Climax]] completes, any opponent caught by Gomorrah with 100% or more damage at the end of the attack will be instantly KO'd.

* Danger Zones in [[The Great Cave Offensive]] damage and launch players similarly to [[lava]]; if they have 100% or more damage, however, the player will be instantly KO'd.

* On [[Midgar]], when the main platform is cleaved apart by [[Odin]], the two halves of the stage will eventually reconnect. Any fighter caught in the middle when this happens will be crushed.

* {{SSBU|Hero}}'s [[Command Selection|Kamikazee]] uniquely instantly KO's ''himself'', damaging foes caught in the blast.

* Hero's [[Command Selection|Whack]] and [[Command Selection|Thwack]] have a chance to instantly KO an opponent, with a higher probability the higher both the user and opponent's percentages are.

* {{SSBU|Bowser}}'s [[Giga Bowser Punch]] can instantly [[Screen KO]] fighters with 60% or more after being punched (80% when using the weaker version via [[Final Smash Meter|FS Meter]]). In situations in which a Screen KO cannot occur, it instead forces the opponent to be KO'd via the upper blast line, resulting in a [[blast KO]] or [[Star KO]] instead.

* {{SSBU|Joker}}'s [[All-Out Attack]] can instantly KO fighters with 100% or more damage at the end of its animation. If the last stock is taken with this attack, the game instantly ends and a unique victory screen is played.

* {{SSBU|Sora}}'s [[Sealing the Keyhole]] can instantly KO fighters with 100% or more damage at the end of its animation.

* [[Death's Scythe]] will instantly KO when striking a fighter at or above 70% damage with the tip of the scythe using a fully charged smash attack, 80% damage using an uncharged smash attack, and 120% using a tilt attack.

* ''Ultimate'' is the first game in the series where [[Stamina Mode]] can be played with multiple [[stock]]s. Under these conditions, fighters who lose all [[hit points|HP]] with more than one stock left suffer an instant KO and [[revival platform|respawn]], taking away one stock. When the last stock is lost, the standard Stamina Mode KO occurs with the fighter falling to the ground and lying there motionless, then exploding and disappearing for good (unless they can use [[Share stock]] in a team battle) after a short pause.
