Editing Sacrificial KO

A '''sacrificial KO''' (also called a '''kamikaze''', a '''suicide''' or a '''trade-off''') is a technique that has appeared in all installments of the ''{{b|Super Smash Bros.|series}}'' series, where one character [[KO]]s both themselves and an opponent with a single move. A majority of sacrificial KOs involves attacks that can [[grab]] opponents in midair, though a number of other attacks, such as [[stall-then-fall]] aerials and self-damaging attacks with self-knockback, can also be considered sacrificial KOs. 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.

|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 closest to the blast line will always lose. The character that landed the grab in a losing position can evade a loss by opting to [[throw]] the other character instead.

|Bowser always loses.

|"Dededecide" is executed by [[Inhale (King Dedede)|inhaling]] an enemy and walking off-stage. While generally safe due to King Dedede's long, safe recovery, spitting the victim underneath the stage for a stage spike is generally more effective.

|"[[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 was 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 via mashing (leaving Kirby to [[self-destruct]]), and the last 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, Wario, and K. Rool by copying their abilities, with identical behavior involving the last stocks.

|"Robincide" is executed by using [[Nosferatu]] on an opponent while off-stage, causing both to fall downwards slowly. This is impractical, as it is hard to land, can be mashed out of, and can only be used four times per tome (three in ''Ultimate'').

|Chrom's up special move [[Soaring Slash]] contains a powerful meteor smash, which can reliably KO opponents at any percentage, although Chrom must sacrifice his stock to meteor smash with the move provided there is no ledge to grab, as both characters will plummet to the bottom blast zone. This is called "Chromicide", and is very similar to Aethercide, due to Soaring Slash being incredibly similar to Aether.

|"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. In certain stages built with the [[Stage Builder]], Cloud can use [[Omnislash / Omnislash Ver. 5]] to plummet to the blast zone as the victim and Cloud dive.

|In ''Smash 4'', 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.

 

In ''Ultimate'', Cloud always wins as long as the downward slash deals enough knockback.

|"Incinicide" is executed with [[Cross Chop]]. If Incineroar uses Cross Chop hits an opponent with the meteor hitbox and plummet offstage, both characters will plunge towards the bottom blast zone. Incineroar can easily set this up with a down throw.

|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. Results in only Little Mac self-destructing if he mistimes the attack or the opponent air dodges. One of the custom special moves, Grounding Blow, can also act similarly to Cloudicide or Aethercide, as it meteor smashes the opponent while also having Little Mac plummeting.

|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'', King Dedede usually wins, but certain situations can cause him to cross the blast lines before the opponent, typically if they are at relatively low percents. In ''Ultimate'', King Dedede always wins, as long as the falling portion deals enough knockback.

|[[Soaring Axe Kick]]'s heel can drag down opponents along with them when it is used off-stage, resulting in both of their stocks lost. [[Head-On Assault]] can be used the same way, either offstage or after a [[jab cancel]]. It should be noted that using either special move while facing and positioned close to a ledge is technically not a sacrificial KO, as the Brawler will grab the ledge while their victim is left to plummet into the abyss. Note that in ''Ultimate'', the descending attack of Soaring Axe Kick is optional.

|Dependent on the height, damage percentage, and falling speed of the Brawler and their victim in ''Smash 4''. In ''Ultimate'', Mii Brawler always wins as long as the falling portion of both moves deals enough knockback.

|Much like Climhazzard and Aether, the descent of [[Stone Scabbard]] will meteor smash opponents, but the Mii Swordfighter can be KO'd first if they do not grab the ledge after connecting the move.

*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. It should be noted that with [[stall-then-fall]] attacks the user is nearly guaranteed to be KO'd unless they perform the aerial very high up.

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 some players claiming that the winner of the game should be determined by the game and not by observers.
