A '''one-hit KO''', commonly abbreviated as '''OHKO''' (also referred to as an ''Instant KO'' in ''Melee''), is an attack in the ''{{b|Super Smash Bros.|series}}'' games with such high base [[knockback]] that it [[KO]]s an opponent at 0%. Such attacks currently exist in every installment of the series.

A '''one-hit KO''', commonly abbreviated as '''OHKO''', is an attack in the ''{{b|Super Smash Bros.|series}}'' games with such high base [[knockback]] that it will [[KO]] an opponent at 0%. Such attacks currently exist in every installment of the series.


In general, a move is considered a one-hit KO if:
==Definition==
In general, a move is considered a one-hit KO if it inflicts enough knockback to KO [[Mario]] at 0% from the middle of [[Final Destination]] ([[Dream Land]] in ''[[Smash 64]]'').


*It is capable of KOing [[Mario]] at 0% ''through sheer knockback alone'' from the middle of the respective game's [[Final Destination]].
As a result, moves and situations like the following are not considered to be one-hit KOs:
*It is not a [[meteor smash]] unless the hitboxes are also capable of OHKOing onstage (meteor smashes like those [[Beast Ganon]] are therefore OHKOs, while [[Luigi]]'s down taunt is not).
* [[Meteor smash]]es that only work offstage, such as [[Luigi]]'s down [[taunt]]
*It deals damage and/or does not cause a KO by forcibly re-positioning the opponent (such as [[push]] effects and dragging [[Final Smash]]es. There are some exceptions, such as [[Jigglypuff]]'s [[Puff Up]] in ''[[Brawl]]'' which has both sheer OHKO power and an extreme push effect, and [[Samus]]' [[Zero Laser]] in the same game, which has dragging hits before the final hit).
* Moves or hazards that inflict no [[knockback]], such as being flown off the screen by the [[Landmaster]] or eaten by the [[Summit]]'s [[Fish]] or [[Distant Planet]]'s [[Bulborb]]
*It is not extremely situational (such as the first hit of [[Roy]]'s [[Blazer]] against [[Jigglypuff]] in ''Melee'', or Jigglypuff's uncommonly high [[shield jump]]).
* [[Sacrificial KO]]s such as [[Bowser]]'s [[Flying Slam]], due to also inflicting no knockback
* Moves that only work on certain light characters (such as the first hit of {{SSBM|Roy}}'s [[Blazer]] against {{SSBM|Jigglypuff}} on specific [[stage]]s in ''[[Melee]]'')
* Moves that only work on certain stages (such as [[Ike]]'s [[Great Aether]] on [[75m]]), with stage hazards being an exception
* [[Instant KO]]s such as [[Hero]]'s [[Whack]], due to inflicting no knockback


Another common standard is to compare the move's knockback to the [[smash attack]] of the [[Home-Run Bat]], one of the few moves intended to be the quintessential OHKO by the developers.
Conversely, a one-hit KO move may fail to KO if the standard conditions are not met, such as the stage being large or having [[wall]]s; the opponent being at the far end of a stage; the move being weakened due to [[stale-move negation]]; or the opponent using [[DI]], [[momentum cancel]]ling, [[crouch cancel]]ling, or various other techniques to reduce the knockback or alter the trajectory of the attack.
 
Moves with the potential to OHKO are not necessarily guaranteed to do so, and may fail to OHKO under the following circumstances:
*The opponent [[tech]]s, [[DI]]s, utilizes [[momentum cancel]]ling, and/or [[crouch cancel]]s to reduce the knockback or alter the trajectory of the attack.
*The opponent is flung into a wall, which absorbs enough knockback to prevent the OHKO.
*Knockback may be insufficient to KO at 0% on very large stages (e.g. [[Temple]], [[New Pork City]], and [[75m]]), or from the far edge of a stage.
*Knockback may be insufficient to KO at 0% if the attack had already been landed previously (due to [[stale-move negation]]).
*Knockback may be insufficient to KO [[Weight|heavy]] characters at 0%.
*Opponents are under an effect that makes them more resilient (such as being [[Super Mushroom|giant]], [[metal]], or in an event that reduces the knockback they sustain), or the player is weakened (such as being [[Poison Mushroom|tiny]] or given a lower [[handicap]]).
*The [[launch rate]] is lower than standard, reducing knockback.
 
=Trivia=
 
*The [[Home-Run Bat]] is the only [[item]] able to perform a guaranteed OHKO in every ''Smash''game.
*[[Marth]]'s [[Critical Hit]] is the only [[Final Smash]] to mantain its OHKO power in every installment. In [[Brawl]], it is also the most powerful playable attack ever of the ''Smash'' serie, without any external buff.
*[[Tabuu]] on Intense [[Difficulty]] in the [[Subspace Emissary]] has more [[OHKO]]s than every other [[boss]] or [[enemy]] in all the "Smash" games: even 10, beating [[Galleom]]'s 5. They are reduced to 8 in [[Boss Battle]], although some of them are not always guaranteed anymore, needing [[sweetspot]]. Several other Tabuu's attacks are an invariable KO as low as 20% on higher [[Difficulty|difficulties]].
*[[Tabuu]]'s [[Off Waves]] or touching [[Winged Tabuu]] on Intense [[Difficulty]] in the [[Subspace Emissary]] and [[Boss Battle]] are the most powerful [[OHKO]] attack in every ''Smash'' game, both for damage (over 100% to 200%) and immense knockback. The [[Ultimate Chimera]]'s bite in [[Brawl]] also inflicts enormous knockback and 100% or 200% damage (if sweetspotted).

=List of One-Hit KOs=
This page lists the moves that can OHKO within the rules mentioned above.
 
Certain moves and situations are '''not''' considered to meet the definition of one-"''hit''" KO's:
 
*Moves or hazards that inflict no knockback (for example, being flown off the screen by the [[Landmaster]] or eaten by the [[Summit]]'s [[Fish]] or [[Distant Planet]]'s [[Bulborb]]), as they simply move opponents into the blast lines.
*[[Sacrificial KO]]s and [[instant KO]]s (such as [[Bowser]]'s [[Flying Slam]] or [[Hero]]'s [[Whack]]), as they do not deal any conventional knockback.
*Moves that hit an opponent who is close to a [[blast line]] (such as [[Pikachu]]'s [[Thunder]]), as almost any typical attack ingame will be able to KO opponents at that point.
 
Some [[stage hazard]]s or [[enemies]] are capable of OHKOing on their respective stages, and will be listed below.


==In ''[[Super Smash Bros.]]''==

==In ''[[Super Smash Bros. Brawl]]''==
==In ''[[Super Smash Bros. Brawl]]''==
''Brawl'' continued the trend of adding several OHKOs into the game, resulting in a huge number of them (especially in [[The Subspace Emissary]]). However, the majority are [[Final Smash]]es, [[item]]s, [[stage hazard]]s, [[enemy]] and [[boss]] attacks, with relatively few being standard moves of playable [[character]]s.
Despite [[The Subspace Emissary]] automatically increasing the player's [[gravity]] and [[falling speed]] by up to 19% from normal brawls (making OHKOs less likely), ''Brawl'' features the largest amount of OHKOs, with the vast majority being from [[boss]]es.
In higher [[Difficulty|difficulties]] of [[The Subspace Emissary]] (often Very Hard or Intense), several [[enemy]] attacks are invariable OHKOs, as well as many [[boss]] attacks. Also, most of [[Tabuu]]'s moves are guaranteed OHKOs in every situation, some of them even in the higher [[Difficulty|difficulties]] of [[Boss Battle]] (where the player has only one life).


===Playable characters' standard moves===
===Playable characters' standard moves===
*{{SSBB|Ike}}'s stage 8 [[Eruption]]. If Ike gets [[Inhale|inhaled]] by [[Kirby]], the latter's stage 8 Eruption loses its OHKO power (except when reversed or used in midair).
*{{SSBB|Ike}}'s stage 8 [[Eruption]]. Requires the [[stale-move negation|freshness bonus]] and therefore does not work in Training mode.
*{{SSBB|Mr. Game & Watch}}'s fully loaded [[Oil Panic]] after absorbing three strong projectiles (such as [[PK Flash]]) or a very strong one.
*{{SSBB|Mr. Game & Watch}}'s fully loaded [[Oil Panic]] after [[absorb]]ing three medium power [[projectile]]s (such as three [[PK Flash]]es) or a very strong one.
*The following [[counterattack]]s:
*The following [[counterattack]]s:
**{{SSBB|Ike}}'s Counter (sword and body hitboxes) upon countering a hitbox that deals at least ~40% damage.
**Ike's Counter (sword and body hitboxes) upon countering a hitbox that deals at least ~45% damage.
**{{SSBB|Marth}}'s Counter (sword and body hitboxes) upon countering a hitbox that deals at least ~45% damage.
**{{SSBB|Marth}}'s Counter (sword and body hitboxes) upon countering a hitbox that deals at least ~50% damage.
 
*Any sufficiently strong or repeatedly [[Reflector|reflected]] projectile when reflected or countered, such as {{SSBB|Zelda}}'s [[Din's Fire]], or a [[Green Shell]].
Contrary to common belief, Mr. Game & Watch's [[Judge]] #9 is not a OHKO, having very high knockback but not quite enough to qualify under the required conditions (it usually KOs [[Mario]] starting from 10%). The same applies to {{SSBB|Ike]}}'s stage 7 [[Eruption]], which can KO [[Charizard]] as low as 8% but doesn't respect the general definition.
{{SSBB|Sheik}}’s [[Chain]] with the [[Chain Jacket glitch]] can also copy another hitbox, including a hitbox of OHKO power.


===Final Smashes===
===Final Smashes===
*{{SSBB|Marth}}'s [[Critical Hit]]. It is also the most powerful player attack of all ''Smash'' games in term of knockback, without any exterior factors or buffs.
*Marth's [[Critical Hit]].
*{{SSBB|Jigglypuff}}'s [[Puff Up]] both by [[push]] and simple contact (the hitbox when Jigglypuff begins deflating has extremely high base knockback in ''[[Brawl]]'').
*{{SSBB|Lucario}}'s [[Aura Storm]] at high enough [[Aura]] (Lucario's damage must be at least 95%) if all hits connect, including the initial take-off.
*{{SSBB|Ganondorf}}'s [[Beast Ganon]] (if most hitboxes land). If a character paralyzed by Beast Ganon is not hit by the charge afterward, they will be inflicted a [[meteor smash]] of OHKO power.
*{{SSBB|Pokémon Trainer}}'s [[Triple Finish]] if most hits connect, including the last one.
*{{SSBB|Lucario}}'s [[Aura Storm]] at max [[Aura]] if all hits connect.
*{{SSBB|Ganondorf}}'s [[Beast Ganon]] if most hitboxes land (at least one stomp and charge).
*{{SSBB|Zelda}}'s [[Light Arrow]] (barely in OHKO threshold, easily [[DI]]ed).
*Zelda's [[Light Arrow]] (first opponent only).
*[[Pokémon Trainer]]'s [[Triple Finish]] (barely in OHKO threshold).
*{{SSBB|Samus}}' [[Zero Laser]] if all hits connect.
*{{SSBB|Samus}}' [[Zero Laser]] if all hits connect.
*{{SSBB|Olimar}}'s [[End of Day]] if all hits connect (bury, ascent, and explosion). Offstage opponents hit by the rocket's thrusters will also experience an OHKO via [[meteor smash]].
*{{SSBB|Olimar}}'s [[End of Day]] if all hitboxes land (bury, ascent, and explosion).
*[[Wario-Man]]'s fully charged [[Wario Waft]].
*{{SSBB|Captain Falcon}}'s [[Blue Falcon]].
*[[Wario-Man]]'s [[Wario Waft]] fully charged.
 
While close, {{SSBB|Luigi}}'s [[Super Jump Punch]] during [[Negative Zone]] is not quite strong enough, only KOing Mario at 5% and Bowser around 7%. Negative Zone inflicts incremental damage and can easily break these thresholds, but this damage does not consist of "hits" due to inflicting no knockback.

*[[Suicune]]'s Aurora Beam. The beam will not [[freeze]] at 0%, but still deals more than enough knockback to invariably OHKO.
*[[Electrode]]'s Explosion when smash thrown. If an Electrode fails to burst, it can still be picked up and smash thrown with OHKO power.
*[[Deoxys]]'s Hyper Beam or touching Deoxys, both the initial hit and the following multi-hitting laser.

*If {{SSBB|Wario}} runs over a buried [[Pitfall]] while riding on his [[Wario Bike]], he will be sent flying at OHKO power.
*If a [[Pitfall]] is thrown on a flying character, he will be [[meteor smash|meteor smashed]] with a OHKO potential if he is midair.
*If an uncharged Hothead is hit by an [[electric]] or [[flame]]-based hitbox that deals at least 30% damage (such as {{SSBB|Ike}}'s stage 6-9 [[Eruption]]), it will OHKO when smash thrown or launched. Coming into contact while it is sparking will also OHKO.
*When an [[Hothead]] reaches its full power for the last seconds (emitting sparks), any contact will be a OHKO. If an uncharged Hothead is hit by a [[flame]]-based hitbox that deals over 30% damage (such as Ike's stage 7-9 Eruption), it will OHKO when smash thrown. Any sparks it gives off while traversing the stage at this strength will also OHKO.
*If a [[Soccer Ball]] is launched at enough speed (after either being hit by an extremely powerful attack such as [[forward smash]] or a Home Run bat swing, or simply being launched after receiving enough damage), it will OHKO anyone it slams into.
*If a [[Soccer Ball]] is launched at enough speed (after either being hit by an extremely powerful attack such as [[forward smash]], a Home Run bat swing, or being launched after receiving enough damage), it will OHKO anyone it slams into.

===The Subspace Army (enemies and clones)===
===Bosses===
The following will usually cause a OHKO on Intense [[difficulty]] only:
Due to [[Boss Battles]] mode weakening bosses (to compensate for the player's single [[stock]] and lack of continues, items, or [[sticker]]s), all of the following apply only to {{SSBB|Classic Mode}} or [[The Subspace Emissary]], and cannot OHKO in Boss Battles mode on any difficulty with a single exception. [[Tabuu]]'s Off Waves will still OHKO in Boss Battles on Intense difficulty.
*[[Big Primid]]'s and other [[Primid|Primids]]' punch.
* {{SSBB|Master Hand}} and {{SSBB|Crazy Hand}}'s Reverse Throw (Intense).
*The [[forward smash]] of all four [[R.O.B.]]s.

*[[Spaak]]'s thunder.
*[[Towtow]]'s charge.
*The most powerful attacks of [[Shadow Bug|Shadow Clones]], such as [[forward smash]] and [[up smash]].


The following will cause a OHKO on both Very Hard and Intense [[Difficulty|difficulties]]:
===Other===
*[[Armank]]'s main attack.
* In [[Cruel Brawl]], the Red Alloy's forward smash can OHKO from the center of the stage even on {{SSBB|Bowser}}.{{fact}}
*[[Autolance]]'s slash.
*Touching a [[Bombed]].
*[[Floow]]'s mind attack (if most hits connect or at full health).
*[[Bytan|Giant Bytan]]'s full power charge (at low health).

The following will cause a OHKO on every [[difficulty]]:
*Multiple [[Floow|Floows]]' combined mind attack (together, if most hits connect or at full health).
*[[Scope Primid]]'s most powerful projectile.
 
Touching a [[Trowlon]] on every [[difficulty]] is not a OHKO in conventional terms, since it simply carries the player beyond the top blast line, KOing regardless of damage.
 
Many other enemies and several [[Shadow Bug|Shadow Clones]] are also capable of OHKOs.
 
===The Subspace Army (bosses)===
The following will usually cause a OHKO on Intense [[difficulty]] only:
*[[Rayquaza]]'s Blast at low health (25%).
*[[Rayquaza]]'s Lightning Strike if most hits connect or at low health (25%).
*[[Porky Minch]]'s Lightning (if most hits connect).
*[[Ridley]]'s Background Ram (sweetspot).
*[[Ridley]]’s Slamming Rush.
*[[Duon]]'s Jump Crash.
*[[Duon]]'s Vacuum Spin (if most hits connect).
*[[Galleom]]'s Shockwave (first hit only).

*[[Galleom]]'s Falling Body Slam.
*[[Galleom]]'s Tornado Spin (if most hits connect).
*[[Tabuu]]'s Pinpoint Explosion.
*[[Tabuu]]'s Bullet Rain (second attack).
 
The following will cause a OHKO on Hard or higher [[Difficulty|difficulties]]:
*[[Tabuu]]'s Golden Bracket. Due to perfectly horizontal knockback, this attack is a guaranteed OHKO for poor [[recovery]] characters even on Easy [[difficulty]].
*[[Tabuu]]'s Dragon Laser.
*[[Tabuu]]'s Chain of Light. When two [[Player|players]] fight, Tabuu will attempt to smash them together with the Chain, resulting in a potential double OHKO.
 
The following will cause a OHKO on Normal or higher [[Difficulty|difficulties]]:
*[[Tabuu]]'s [[Off Waves]] or touching [[Winged Tabuu]] (invariable).
 
The following will cause a OHKO on every [[difficulty]]:
*[[Porky Minch]]'s Energy Laser if most hits connect or Porky has low health (25%).

*[[Meta Ridley]]’s Falcon Flyer Stamp.
*[[Tabuu]]'s [[Off Waves]] or touching [[Winged Tabuu]] (sweetspot).
 
[[Meta Ridley]]'s Falcon Flyer Pull on every [[difficulty]] is not a OHKO in conventional terms, since it simply pulls the player beyond the bottom blast line, KOing regardless of damage. The only way to survive it is jumping.
 
Other [[boss|bosses]]' attacks are also capable of OHKOs.
 
===Classic Mode (bosses)===
The following will usually cause a OHKO on Intense [[difficulty]] only:
*[[Master Hand]]’s Finger Drill (if most hits connect).

*[[Crazy Hand]]’s Fake-Out Slap.
*[[Crazy Hand]]’s Power Punch.

*[[Master Hand]]’s and [[Crazy Hand]]’s Jestream (sweetspot).
*Combined [[Master Hand]]’s and [[Crazy Hand]]’s Sandwich Punch (invariable).
 
The following will cause a OHKO on both Very Hard and Intense [[Difficulty|difficulties]]:
*Combined [[Master Hand]]’s and [[Crazy Hand]]’s Applause (if most hits connect).
*Combined [[Master Hand]]’s and [[Crazy Hand]]’s Sandwich Punch (sweetspot).
 
===Boss Battle (bosses)===
The following will usually cause a OHKO on Intense [[difficulty]] only:
*[[Duon]]'s Sword Blast (sweetspot; the hit itself, not the shockwave).
*[[Meta Ridley]]’s Mega Fire Ball (sweetspot).
*[[Galleom]]'s Tank Rush and Slam (sweetspot; only used by [[Galleom|Tank Galleom]] at very low health).
*[[Galleom]]'s Falling Body Slam (sweetspot).
*[[Galleom]]'s Tornado Spin (if most hits connect).
*[[Tabuu]]'s Chain of Light. When two [[Player|players]] fight, Tabuu will attempt to smash them together with the Chain, resulting in a potential double OHKO.
*Touching [[Tabuu]] through Electrical Shield (sweetspot).
*[[Tabuu]]'s Shark Blade (sweetspot).
*[[Tabuu]]'s Pinpoint Explosion.
*[[Tabuu]]'s Bullet Rain (second attack).
 
The following will cause a OHKO on both Very Hard and Intense [[Difficulty|difficulties]]:
*[[Porky Minch]]'s Energy Laser if most hits connect or Porky has low health (25%).
*[[Tabuu]]'s Golden Bracket. Due to perfectly horizontal knockback, this attack is a guaranteed OHKO for poor [[recovery]] characters even on Normal [[difficulty]].
*[[Tabuu]]'s Dragon Laser.
 
The following will cause a OHKO on Hard or higher [[Difficulty|difficulties]]:
*[[Tabuu]]'s [[Off Waves]] or touching [[Winged Tabuu]] (invariable).
 
The following will cause a OHKO on Normal or higher [[Difficulty|difficulties]]:
*[[Tabuu]]'s [[Off Waves]] or touching [[Winged Tabuu]] (sweetspot).
 
The following will cause a OHKO on every [[difficulty]]:
*[[Meta Ridley]]’s Falcon Flyer Smash.
*[[Meta Ridley]]’s Falcon Flyer Stamp.
 
[[Meta Ridley]]'s Falcon Flyer Pull on every [[difficulty]] is not a OHKO in conventional terms, since it simply pulls the player beyond the bottom blast line, KOing regardless of damage. The only way to survive it is jumping.
 
Other [[boss|bosses]]' attacks are also capable of OHKOs.
 
===Others===
 
In [[Cruel mode|Cruel Brawl]], several attacks of the [[Fighting Alloy Team]] are powered so much that they can easily OHKO every character. These moves include, for example, [[forward smash]] and [[up smash]], but also punches and kicks. Each of the [[Fighting Alloy Team|Alloys]] has more powerful specific attacks, such as kicks for the [[Fighting Alloy Team|Blue Alloy]] or punches for the [[Fighting Alloy Team|Red Alloy]], which are both a guaranteed OHKO from the center of the stage even for [[Bowser]]. The same strengthening, or maybe a bit less, was already seen in [[Melee]].

*In ''[[Melee]]'', {{SSBM|Roy}}'s trophy refers to [[Flare Blade]] as an "instant KO".

*While the majority of OHKOs will fail to work on characters under the effects of a [[Super Mushroom]] or [[Metal Box]], a few attacks have such high knockback that they will still OHKO under these circumstances. In ''Brawl'', this includes [[Suicune]]'s Aurora Beam, Marth's Critical Hit, the [[Ultimate Chimera]]'s bite, and several [[boss]] attacks.
**Starting from ''Smash 4'', a few Final Smashes have hitboxes that negate the effects of such buffs, such as Marth's Critical Hit.
*Tabuu on Intense difficulty in [[The Subspace Emissary]] has more OHKOs than any other boss or enemy in any ''Smash'' game, with 7.
*The most powerful moves in the ''Smash'' series are Tabuu's Off Waves (waves and contact with his body) on Intense difficulty in The Subspace Emissary and Boss Battles, and the Ultimate Chimera's bite in ''Brawl''. Both these attacks are the most damaging moves, dealing 100%-200% damage and having immense knockback.
*Master Core's final explosion on 8.0 difficulty or above is the only OHKO that will never KO the player, since the battle is always already won by the time the hitboxes land.
**Galleom's Tank Rush and Tank Rush & Slam can also hit the player after the boss is defeated, with OHKO power on the higher difficulties.

Latest revision as of 11:52, December 16, 2024

This article is about attacks with enough knockback to KO in one hit. For KOs that occur instantly and bypass all knockback, see Instant KO.
"OHKO" redirects here. For the smasher sometimes known as "OHKO", see Smasher:Okoru.
Roy’s Flare Blade is an example of a one-hit KO move.

A one-hit KO, commonly abbreviated as OHKO, is an attack in the Super Smash Bros. games with such high base knockback that it will KO an opponent at 0%. Such attacks currently exist in every installment of the series.

Definition[edit]

In general, a move is considered a one-hit KO if it inflicts enough knockback to KO Mario at 0% from the middle of Final Destination (Dream Land in Smash 64).

As a result, moves and situations like the following are not considered to be one-hit KOs:

Conversely, a one-hit KO move may fail to KO if the standard conditions are not met, such as the stage being large or having walls; the opponent being at the far end of a stage; the move being weakened due to stale-move negation; or the opponent using DI, momentum cancelling, crouch cancelling, or various other techniques to reduce the knockback or alter the trajectory of the attack.

In Super Smash Bros.[edit]

Moves that KO at 0% are almost nonexistent in the original Super Smash Bros. In fact, aside from the Home-Run Bat, only one move in the game is able to OHKO, and only under uncommon conditions involving items.

Items[edit]

Video[edit]

The following video demonstrates the main moves that KO at 0% in Smash Bros. for the Nintendo 64:

In Super Smash Bros. Melee[edit]

Playable characters[edit]

While close, Mr. Game & Watch's Judge #9 is not quite strong enough to KO at 0%.

Items/Enemies[edit]

Stage hazards[edit]

  • Rapid laser shots from the Great Fox on Corneria, as well as the turrets while the Great Fox is charging.
  • On Flat Zone, if a falling tool is launched at enough speed (after either being hit by an extremely powerful attack such as a Home-Run Bat swing, or being launched after receiving enough damage), it will OHKO anyone it slams into.
  • Banzai Bill's explosion on Princess Peach's Castle (if all hits connect).
  • Touching a blue Klaptrap on Jungle Japes.

1-P Mode[edit]

Video[edit]

The following video demonstrates nearly all the moves and hazards that KO at 0% in Melee:

In Super Smash Bros. Brawl[edit]

Despite The Subspace Emissary automatically increasing the player's gravity and falling speed by up to 19% from normal brawls (making OHKOs less likely), Brawl features the largest amount of OHKOs, with the vast majority being from bosses.

Playable characters' standard moves[edit]

Sheik’s Chain with the Chain Jacket glitch can also copy another hitbox, including a hitbox of OHKO power.

Final Smashes[edit]

While close, Luigi's Super Jump Punch during Negative Zone is not quite strong enough, only KOing Mario at 5% and Bowser around 7%. Negative Zone inflicts incremental damage and can easily break these thresholds, but this damage does not consist of "hits" due to inflicting no knockback.

Items[edit]

  • The Dragoon.
  • A smash attack with the Home-Run Bat.
  • Touching Moltres.
  • Suicune's Aurora Beam.
  • Deoxys's Hyper Beam.
  • Electrode's Explosion when smash thrown. If an Electrode fails to burst, it can still be picked up and smash thrown with OHKO power.
  • If Wario runs over a buried Pitfall while riding on his Wario Bike, he will be sent flying at OHKO power.
  • If an uncharged Hothead is hit by an electric or flame-based hitbox that deals at least 30% damage (such as Ike's stage 6-9 Eruption), it will OHKO when smash thrown or launched. Coming into contact while it is sparking will also OHKO.
  • If a Soccer Ball is launched at enough speed (after either being hit by an extremely powerful attack such as forward smash or a Home Run bat swing, or simply being launched after receiving enough damage), it will OHKO anyone it slams into.

Stage hazards[edit]

  • The Ultimate Chimera's bite on New Pork City.
    • If the bite lands on the mouth's edge, it deals immense knockback, comparable to Marth's Critical Hit. If the bite traps the character inside the mouth (or the Ultimate Chimera turns around to inflict a reverse bite), the attack hits twice, dealing even more knockback.
  • Corneria's laser beams.
  • Touching the hull of the Pirate Ship.
  • The first and fourth spikes on Rumble Falls (can easily be teched).
  • Touching a Klaptrap on Jungle Japes.

Bosses[edit]

Due to Boss Battles mode weakening bosses (to compensate for the player's single stock and lack of continues, items, or stickers), all of the following apply only to Classic Mode or The Subspace Emissary, and cannot OHKO in Boss Battles mode on any difficulty with a single exception. Tabuu's Off Waves will still OHKO in Boss Battles on Intense difficulty.

  • Master Hand and Crazy Hand's Reverse Throw (Intense).
  • Rayquaza's Iron Tail (low HP, sweetspot/tip, Intense). Can be teched.
  • Galleom's Collapse (sweetspot, Very Hard).
  • Galleom's Collapse (sourspot), Double Lariat (all hits connect), Giant Jump (landing directly on opponent, low HP), Uppercut (sweetspot, low HP), and Rush & Slam (against grounded opponents, low HP) (all Intense).
  • Meta Ridley's Mega Fire Ball (low HP) and Falcon Flyer Pull (giant fireball at point-blank) (all Intense).
  • Tabuu's Off Waves (any difficulty at less than half HP, Normal at any HP).
  • Tabuu's Movement Throw (Hard), Tabuu Shot (Very Hard), Blade Charge (less than half HP, Very Hard), Shadow Laser (Intense), Discharge Attack (body, Intense), Tabuu Fire (Intense).

Other[edit]

Video[edit]

The following video demonstrates some moves and hazards that KO at 0% in Brawl:

This video shows some other OHKOs, including more boss attacks.

In Super Smash Bros. 4[edit]

Playable characters' standard moves[edit]

Contrary to its name and intention, Little Mac's KO Uppercut does not KO until above about 30% damage. At 0%, it falls short of the necessary amount of knockback, KOing a character as light as Jigglypuff at 12%.

With Rage applied[edit]

Final Smashes[edit]

Items[edit]

  • The Dragoon.
  • A smash attack with the Home-Run Bat.
  • Electrode's Explosion after being smash thrown.
  • If a Hothead is powered up significantly by a flame- or electric-based hitbox (30% total or higher), it will gain OHKO power when smash thrown or emitting sparks.
    • Equipment can increase the player's damage, increasing the amount of damage a Hothead can be charged by and thus making it easier to reach OHKO power.
  • The Black Knight item from Smash Tour will cause smash attacks to have a 30% chance to have 5 times knockback, occasionally turning them into OHKOs.

Stage hazards[edit]

Bosses[edit]

  • Master Core's final wave attack (on 8.0 or higher intensity only[citation needed]). Ironically, the chances to survive are higher if the player is closer to the blast lines.
  • Master Core's self-destruction after unleashing the last wave (very small hitbox). However, this knockback can never defeat the player as they have already won by the time the hitbox lands.

Other[edit]

While it isn't accessible in regular battles, the bomb used in the Target Blast stage has enough power to OHKO.

Video[edit]

The following video demonstrates all the moves and attacks that KO at 0% in Smash 4:

Playable characters' moves[edit]

With Rage applied[edit]

Final Smashes[edit]

Final Smashes executed using Final Smash Meter always lose their OHKO power, with Critical Hit KOing Mario at 20%.

Items[edit]

  • The Dragoon.
  • A smash attack with the Home-Run Bat.
  • Electrode's Explosion when smash thrown.
  • A Hothead when brought from no charge to significant overcharge by a single flame or electric attack that deals over 50% damage. If the Hothead hits while sparking, it can OHKO from attacks closer to 30%.
    • Spirits can increase the player's damage, increasing the amount of damage a Hothead can be charged by and thus making it easier to reach OHKO power.
  • The Deku Nut's explosion on a grounded target that cannot be stunned, such as Sandbag, or Kirby in his Stone transformation.

Stage hazards[edit]

Other[edit]

While inaccessible in a regular fashion without hacking, the gun found on the Free the Spirit screen's stage is programmed in as its own usable item, inflicting 30% damage with OHKO power (mainly because the Free the Spirit stage is very small with close blast zones).[1] This situation is similar to Smash 4's Target Blast bomb.

Video[edit]

The following video demonstrates all the moves and hazards in Ultimate that inflict enough knockback to KO at 0%, alongside some powerful moves that don't. However, it also includes a few moves and hazards that do not inflict any knockback, such as Instant KOs:

Trivia[edit]

  • In Melee, Roy's trophy refers to Flare Blade as an "instant KO".
  • The Home-Run Bat is the only item (and by extension, the only attack) able to perform a guaranteed OHKO in every Smash game, at least on its sweetspot.
  • Roy's Flare Blade and Counter are the only moves to maintain their OHKO power in every installment.
  • At least one playable character from the Fire Emblem universe possesses a move with OHKO potential in every game. Other main characters appear as items with OHKO power (Black Knight in Smash 4).
  • Marth's Critical Hit is the only Final Smash to maintain its OHKO power in every installment. Throughout all games, it is also the most powerful attack of any character's standard moveset (in terms of knockback) without any exterior factors or buffs, being impossible to survive if in direct sight of a blast line, even on the largest stages of each game.
  • While the majority of OHKOs will fail to work on characters under the effects of a Super Mushroom or Metal Box, a few attacks have such high knockback that they will still OHKO under these circumstances. In Brawl, this includes Suicune's Aurora Beam, Marth's Critical Hit, the Ultimate Chimera's bite, and several boss attacks.
    • Starting from Smash 4, a few Final Smashes have hitboxes that negate the effects of such buffs, such as Marth's Critical Hit.
  • Tabuu on Intense difficulty in The Subspace Emissary has more OHKOs than any other boss or enemy in any Smash game, with 7.
  • The most powerful moves in the Smash series are Tabuu's Off Waves (waves and contact with his body) on Intense difficulty in The Subspace Emissary and Boss Battles, and the Ultimate Chimera's bite in Brawl. Both these attacks are the most damaging moves, dealing 100%-200% damage and having immense knockback.
  • Master Core's final explosion on 8.0 difficulty or above is the only OHKO that will never KO the player, since the battle is always already won by the time the hitboxes land.
    • Galleom's Tank Rush and Tank Rush & Slam can also hit the player after the boss is defeated, with OHKO power on the higher difficulties.
