This article is about KOs that occur instantly with no launching or crossing of blast lines. For launching attacks powerful enough to KO in one hit, see One-hit KO.
Two fighters are thrown into a Danger Zone and instantly KO'd.

An instant KO is a type of KO which occurs instantaneously and in-place, without the fighter passing a blast line or being launched at all. A character suffering an instant KO will disappear into a colorful starburst explosion, then respawn as normal (or not respawn, if no stocks remain). Instant KOs were introduced as stage hazards 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. Ultimate also introduced instant variations of Screen KOs. 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.

In Super Smash Bros. Brawl[edit]

Stage hazards[edit]

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

In Super Smash Bros. 4[edit]

Enemies[edit]

Stage hazards[edit]

  • Danger Zones in Smash Run instantly KO the player regardless of damage.
  • Danger Zones in The Great Cave Offensive damage and launch players similarly to lava; however, if the player has 100% or more damage, they will be instantly KO'd.
  • The interior of Master Fortress is lined with acid-like Danger Zones which cause an instant KO at or above 100% damage.
  • After Midgar is cleaved apart by Odin, the two halves of stage will eventually reconnect. Any fighter caught in the middle when this happens will be crushed.
  • When Midgar is flooded by Leviathan, opponents with 100% or more damage will be instantly KO'd if the current sweeps them into the right side of the stage.

In Super Smash Bros. Ultimate[edit]

Playable characters' standard moves[edit]

  • Hero's Kamikazee instantly KO's himself, damaging foes caught in the blast.
  • Hero's Metal Slash will instantly KO metal opponents and an opposing Hero under the effect of Kaclang.
  • Hero's Whack and Thwack have a chance to instantly KO an opponent, with a higher probability the higher the opponent's percentage is.

Final Smashes[edit]

Items[edit]

  • Poké Ball summon Mimikyu will instantly KO the fighter it grabs hold of if they reach 90% damage after its attack.
  • 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.

Stage hazards[edit]

  • Returning stage Midgar features the same crushing and flood hazards it had in Smash 4.
  • Returning stage The Great Cave Offensive features the same Danger Zones it had in for Wii U.
  • New Pork City is a returning stage with a new hazard: the bite of the Ultimate Chimera now instantly KOs fighters, instead of imparting extreme knockback as it did in Brawl.
  • The Red Bulborb on returning stage Distant Planet instantly KOs fighters with its bite, instead of carrying them off screen as in previous games.

Other[edit]

  • Ultimate is the first game in the series where Stamina Mode can be played with multiple stocks. Under these conditions, fighters who lose all HP will suffer an instant KO and respawn as long as they are not out of stocks. 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 after a short pause.

Trivia[edit]

  • In Ultimate, if Inkling suffers an Instant KO, they do not have a standard explosion animation. Instead, as in the Splatoon games, they burst into a puddle of ink and their spirit, in the form of a squid, flies upward briefly before disappearing. Similarly, Mega Man also has a unique instant KO animation, where he explodes into orbs and makes the same sound as when he dies in his home series.
