A '''sacrificial KO''' (also called a '''kamikaze''' or a '''suicide''') is a technique that has appeared in all installments of the [[Super Smash Bros. (series)|''Super Smash Bros'' series]], where one character [[KO]]s both him or herself and an opponent with a single move. In most cases, this involves grabbing the opponent and dragging him/her downwards to the bottom [[blast line]], though self-damaging attacks can also prove effective. Most sacrificial KOs result in the user [[self destruct]]ing, either by directly KOing them alongside the opponent, or by preventing them from potentially returning to the stage.

Sacrificial KOs are useful if the user has a high percentage and the opponent has a low percentage; as the user is likely to be KOed soon, taking down a comparatively fresh opponent at the same time can even out the match. If the user has a lead in stocks, sacrificial KOs accelerate the match and can even score victories if the victim only has one stock remaining. In the same way, low-damage or trailing players should avoid using sacrificial KOs, as this simply brings them closer to losing. If both players have only one stock remaining, then the user can win, lose, or enter [[Sudden Death]], depending on the exact characteristics of the individual technique.

In ''Smash 4'', most sacrificial KOs were nerfed so that an attempted sacrificial KO causes the attacker to be KO'd before the victim, potentially allowing the victim to return to the stage if their recovery is good enough and making sacrificial KOs much less useful. This discourages the abuse of special moves to perform a sacrificial KO to win a game. The only exception to this rule is {{SSB4|Ganondorf}}'s [[Flame Choke]], as it is more commonly used as Ganondorf's only decent horizontal recovery option, and would see no use off-stage if it caused Ganondorf to be KO'd first.

Sacrificial KOs are typically named by combining the suffix "-cide" with the first part of the character's name; this convention was popularised by American smasher {{Sm|t1mmy}} and his [[machinima]] entitled "[https://www.youtube.com/watch?v=phVFKAxETlg 1-800-KIRBYCIDE]".

!Character!!Applicable games!!Execution!!Last-stocks behaviour
|-
|All characters
|All games
|If one character grabs another character while standing on a piece of terrain that is moving towards a blast line, both characters will be KO'd, as long as the grab is not broken. Stages where this can happen include [[SSB]]'s {{SSB|Mushroom Kingdom}}, [[Great Bay]] (on the turtle), [[Icicle Mountain]], [[Delfino Plaza]], [[Halberd]], [[Mushroomy Kingdom]], [[Rumble Falls]], [[Town and City]], [[Kalos Pokémon League]], [[Wily Castle]], [[PAC-LAND]] and any [[Stage Builder]] stage that has falling platforms that have nothing below them.
|If the platform is rising or falling towards the top or bottom blast line, Sudden Death always occurs. If the platform is moving towards the side blast lines, whoever is closer to the blast line will always lose. The character that landed the grab in a losing position can mitigate a loss by opting to throw the other character instead.
|-
|[[Bowser]]
|''Melee''
|"Bowsercide" is executed by grabbing an airborne opponent with [[Koopa Klaw]] and falling to the blast line with them in hand. Not exceptionally useful; the move can be escaped, and Bowser is unlikely to recover if the opponent does so.
|
|-
|[[Bowser]]
|''Brawl''; ''Smash 4''
|"Bowsercide" is executed with [[Flying Slam]], with Bowser grabbing the opponent and diving off the side of the stage. The move cannot be escaped, but as the lower-damage player has more control over the pair's flight, it is not useful for evening out percentages. While the technique initially returned for {{for3ds}}, [[List of updates (SSB4-3DS)|version 1.0.4]] changed Flying Slam so that Bowser is KO'd before the opponent when the move is performed onto a blast line, making it less useful than in ''Brawl''.
|In PAL and Sudden Death for ''Brawl'', Bowser always wins. In NTSC's ''Brawl'', [[port priority]] determines whether Bowser wins or Sudden Death occurs. In ''Smash 4'', as of 1.0.4, Bowser always loses.
|-
|[[Diddy Kong]]
|''Brawl''; ''Smash 4''
|"Diddycide" is done by using [[Monkey Flip]] on an airborne opponent and letting the pair fall to the blast line. As Diddy jumping during the grab will [[meteor smash]] the opponent, this Sacrificial KO is regarded as impractical, especially due to Diddy Kong's below-average recovery in ''Brawl''.
|In ''Brawl'' and ''Smash 4'' pre-1.0.4, Diddy always wins. In ''Smash 4'', as of 1.0.4, Diddy always loses.
|-
|[[Donkey Kong]]
|All games
|"Kongocide" is executed with Donkey Kong's forward throw, carrying himself and his victim off the stage. This is typically not used as a straight sacrificial KO, as the technique KOs Donkey Kong first; it is generally more useful to throw opponents under or against the stage for a [[stage spike]].
|DK always loses.
|-
|[[Ganondorf]]
|''Brawl''; ''Smash 4''
|"Ganoncide" is done by using [[Flame Choke]] on an opponent with both characters in the air, causing both to plummet downwards. Fast-acting once it connects and inescapable, but very risky to use, as the move causes [[helplessness]] if it misses, and the attack has unpredictable properties when both players are KOed in ''Brawl''. 
|Unpredictable in ''Brawl''; can either be a win or a loss for Ganondorf, as well as potentially causing Sudden Death. It is theorized this has to do with how the upside-down victim's physics bones are located in relation to the right-side up Ganondorf's during their plunge. In ''Smash 4'', Ganondorf always wins.
|-
|[[King Dedede]]
|''Brawl''; ''Smash 4''
|"Dededecide" is executed by [[Inhale (King Dedede)|inhaling]] an enemy and walking off-stage. Dedede can easily recover should the opponent escape, but simply spitting the victim underneath the stage is generally more effective.
|In ''Brawl'', Sudden Death always occurs. In ''Smash 4'', King Dedede always loses.
|-
|[[Kirby]]
|All games
|"[[Kirbycide]]"s are the most famous form of sacrificial KO. Using {{b|Inhale|Kirby}} on enemies and walking off-stage (or inhaling them in mid-air, in ''[[SSB]]'') is highly effective, and in ''Melee'', Kirby can even survive after larger opponents are KO'd out of his stomach; Kirby's long recovery can also prevent him from being KOed in the process, though the efficiency of these KOs were nerfed in later games, with ''Brawl'' generally causing Sudden Death, and ''Smash 4'' causing Kirby to almost always lose, though a Kirbycide with Jumping Inhale will cause a Sudden Death. As such, it is more practical for Kirby to release his opponent before crossing the blast line, then performing another action on them if possible, such as a [[footstool]].
Kirby can also use his forward, back, and up throws as Kirbycides in ''Melee'', though the former two can be escaped (leaving Kirby to simply [[self-destruct]]), and the lattermost is difficult to execute; the back and forward throws cannot Kirbycide in later games, and if the floor underneath Kirby vanishes while he performs the throw, he will automatically let go of the opponent while throwing them. Kirby can also use the sacrificial KOs of Dedede and Wario by copying their abilities.
|Inhale: Kirby almost always wins in ''Smash 64'', and ''Melee''; almost always Sudden Death in ''Brawl''; almost always loses in ''Smash 4''<br>Forward and back throws: Kirby always wins<br>Up throw: Kirby always loses in ''Melee''; [[port priority]] determines the victor in ''Brawl''
|-
|[[Meta Knight]]
|''Brawl''
|"Metacide" is executed by using Meta Knight's up throw when against an edge and under a solid ceiling, possibly causing him and his victim to fall off the stage (possibly influenced by the user's movement). The technique is considered impractical, as it requires precise positioning to perform.
||Meta Knight always loses.
|-
|[[R.O.B.]]
|''Smash 4''
|"Robocide" occurs when R.O.B. uses his up throw when on a moving platform or near an edge, possibly causing him and his victim to fall off the stage, KOing both R.O.B. and his opponent.
||R.O.B. always loses.
|-
|[[Wario]]
|''Brawl''; ''Smash 4''
|"Wariocide" occurs when Wario uses [[Chomp]] while falling, taking his opponent down with him. Difficult to escape from, but not very practical, due to Wario's below-average recovery and the technique's property KOing Wario first.
|Wario always loses in both ''Brawl'' and ''Smash 4''.

==Other sacrificial KOs==
{|class="wikitable"
|-
!Character!!Applicable games!!Execution!!Last-stocks behaviour
|-
|All characters
|All games
|The usage of self-damaging explosives in close ranges is a sacrificial KO, though such instances are often unintentional. Items such as [[Motion-Sensor Bomb]]s, [[Bob-omb]]s, [[Gooey Bomb]]s, [[Electrode]], and other explosives can cause this, as can items spawned by characters, such as Snake's [[Hand Grenade]]s or Duck Hunt's [[Trick Shot]].
|Depends on who suffered more knockback. Sudden Death if both are KO'd at the the same time.
|-
|[[Cloud]]
|''Smash 4''
|"Cloudcide" is executed with [[Climhazzard]]. If Cloud uses the downward slash offstage and hits an opponent with the meteor smash hitbox, both characters will plummet to the bottom blast line.
|Cloud usually loses, but may cause Sudden Death or even allow Cloud to win if he is low enough when he hits the opponent or if either character has high enough damage.
|-
|[[Ike]]
|''Brawl''; ''Smash 4''
|On certain stages built with the [[Stage Builder]], the usage of [[Great Aether]] can result in the move's diving conclusion falling through a hole and KOing Ike and all of his victims. This Sacrificial KO can potentially be negated if enough opponents are trapped in the attack, as they will cause the "tip" of the Final Smash to hit the edge of the pit. If Ike performs a sacrificial KO by using his standard [[Aether]] he will always be KO'd first.
|Sudden Death always occurs. 
|-
|[[Little Mac]]
|''Smash 4''
|Using [[Jolt Haymaker]] offstage to hit an opponent can result in the foe getting KO'd at the side blast line due to the move's high knockback scaling. Little Mac is forced into helplessness once Jolt Haymaker is initiated, and unless the opponent is at medium-high percentages, this results in a net loss for Little Mac if his foe survives the hit and has a good recovery move. Results in only Little Mac self-destructing if he mistimes the attack or the opponent airdodges.
|
|-
|[[King Dedede]]
|''Brawl'', ''Smash 4''
|King Dedede can perform another type of Dededecide via [[Super Dedede Jump]]'s falling portion, which is a [[meteor smash]] that launches enemies downward at the same speed at which King Dedede himself falls. 
|In ''Brawl'', King Dedede always wins. In ''Smash 4'', sudden death always occurs. 
|-
|[[Olimar]]
|''Brawl''; ''Smash 4''
|Similar to Ike's, certain custom stages can cause [[End of Day]] to force Olimar's ship to fall through a hole and KO him. Unless an opponent gets hit by the Meteor Smash of the ship's ascent, this is extremely likely to result in a net loss for Olimar.
|N/A
|-
|[[Jigglypuff]]
|''Smash 4''
|In ''Super Smash Bros. 4'', hitting an opponent with [[Rollout]] will cause Jigglypuff to bounce off the opponent and constantly spin in the air as it falls down to the ground; if no floor is available for it to land on, it is a form of a sacrificial KO, as the player cannot modify Jigglypuff's trajectory unlike in ''Melee'' or ''Brawl''.
|
|-
|[[Mii Brawler]]
|''Smash 4''
|The Brawler's heel in their [[Soaring Axe Kick]] can drag down opponents along with them when it is used off-stage, resulting in both of their stocks lost. It should be noted that an Axe Kick used above a stage's edge is technically not a sacrificial KO, as the Brawler will safely land on the ground while their victim is left to plummet into the abyss.
|Sudden Death always occurs.
|-
|[[Mii Swordfighter]]
|''Smash 4''
|Much like Climhazzard and Aether, the descent of [[Stone Scabbard]] will meteor smash opponents, but the Mii Swordfighter will sacrifice its stock if they do not grab the ledge after connecting the move. Mii Swordfighter will often be KO'ed first.
|
|-
|[[Shulk]]
|''Smash 4''
|Shulk can use [[Back Slash]] offstage to hit a recovering opponent with the move's high range. However, as Back Slash causes Shulk to fall extremely quickly, this often results in a net loss for Shulk unless his active [[Monado Art]] is Smash and the opponent is at an extremely high percentage. Positioning to hit an opponent's back as they recover can [[stage spike]] them and cause them to be KO'd faster than Shulk's falling speed, although the opponent can be sent back onto the stage again if they do not hit the stage's sides. [[Air Slash]] can also cause a sacrificial KO when using the Jump Art after a chain of forward aerials, which can KO opponents at the side blast lines and leaves Shulk helpless regardless if it is successful.
|
|-
|[[Wario]]
|''Brawl''; ''Smash 4''
|When Wario uses his Final Smash to become Wario-Man, if the opponent is at 40% or higher, he can use his [[Wario Bike]] to suicide into the opponent. (Wario can jump off if quick enough, but jumping off will still shoot Wario forward a little, so Wario needs to jump off before he reaches the edge of the screen.)
|Wario always wins.

*Risky [[meteor smash]]es or off-stage aerials generally do not count as sacrificial KOs; the term implies that it is the move that KOs the user, not the fact that the user could not recover after using the move.
*Using a move that KOs an opponent in addition to one's teammate (or one's partner Ice Climber) can be considered a sacrificial KO in some ways, with the main difference being that it is not self-sacrificial.
*Sometimes, Olimar's Pikmin-based attacks will require him to throw a Pikmin off the ledge in order to land a KO. In this case, the loss for Olimar is not equivalent to a stock, and it is generally not considered a sacrificial KO, though it involves a level of "sacrifice".
*Though very uncommon due to how it's set up, characters with throws that send them and their opponents briefly above the upper blast line ({{SSB4|Charizard}}, {{SSB4|Kirby}} and {{SSB4|Meta Knight}}) can be used to perform a Sacrificial KO if an item or projectile acts on the characters at the apex of the throw. An example is if {{SSB4|Mega Man}}'s [[Crash Bomber]] is attached to either character and explodes at the right time during the throw.

==In tournament play==
While rare due to a relatively limited character pool, sacrificial KOs have their own rules within tournaments: If both the victim and initiator are KOed on their last [[stock]] because of a sacrificial KO, the [[results screen]] is ignored and the initiator is deemed the winner. This rule, however, has been disputed, with a minority of players claiming that the winner of the game should be determined by the game and not by observers. 

Additionally, as mentioned earlier for ''Smash 4'', every character except Ganondorf, releases their opponent after they SD, allowing some characters to return to the stage, making this ruling even more questionable. One rule that is seen in some tournaments states that if both players die at the same time (whether a sacrificial KO or not), a tiebreaker match (usually 1 stock, 3 minutes) is to be played on the same stage played before to determine the official winner of the match, ignoring sudden death altogether. Another rule that forgoes tiebreaker matches favors the initiator if the KO results in Sudden Death, but the win is otherwise awarded to whoever is declared the winner on the results screen.

==Trivia==
*If a Sacrificial KO is performed on a [[False character#In the Great Maze|Subspacial clone]] in [[the Great Maze]] while the player is on their last stock and holding an item, the player will reappear in the area they were previously in, no music will be played, and after a few seconds, the screen fades into the Continue screen.
*[[Donkey Kong]] performs a Sacrificial KO on [[Kirby]] in his section of the Super Smash Bros. Melee [[Special Movie]].
