Editing Screen KO

A '''Screen KO''' ({{ja|手前やられ|Temae yarare}}, ''Forefront defeat'') is a special type of [[KO]] which has a chance of occurring when characters are launched past the upper [[blast line]]. In contrast to a [[Star KO]], the character instead falls into the foreground and appears to [[wikipedia:Fourth wall|crash into the screen]], before they are KO'd at the bottom, which is how these KO's got their name.

Whether a character is Star KO'd, Screen KO'd, or merely blast KO'd is mostly random. In the first three games, Screen KOs are considerably rarer than Star KOs; as a result, Screen KOs rarely involve two or more characters at once. From ''[[Super Smash Bros. 4]]'' onward, the frequency of Screen KOs has been increased, especially in the 3DS version of Smash 4, to be about as common as Star KOs.

In ''Smash 64'', characters yell out their Star KO scream and fall down between the front of the stage and the camera, getting KO'd by the bottom blast line afterward. Depending on the camera angle, this may not always be visible. The distance the character is from the camera is chosen randomly — sometimes doomed characters appear to be falling normally, while at other times they are just a quick flash of color going down the screen. Screen KOs have the same duration as a Star KO. Unlike the other games of the series, Screen KO'd characters do not actually hit the screen in any way.

In ''Melee'', all characters, with exception of {{SSBM|Mr. Game & Watch}}, have a unique [[tumbling]] animation for when they crash into the screen; upon striking the camera, the character also exclaims one of their two strong knockback yells (with the exception of {{SSBM|Samus}}), then gets KO'd by the bottom blast line without making any sounds. How close a character being KO'd is to the camera is no longer determined by randomness, but by the stage being played on. On {{SSBM|Mushroom Kingdom}} and [[Mushroom Kingdom II]], for example, Screen KO'd characters are very close to the camera and thus appear much larger. With the introduction of [[Coin Battle]]s, Screen KO'd characters also visibly drop numerous coins when they hit the screen.

While Screen KOs in ''64'' were roughly the same length as star KOs (around 2 seconds), Screen KOs in ''Melee'' are significantly faster than Star KOs (around 1 second). This difference is significant, and can potentially affect gameplay. For example, when a character is KO'd by {{SSBM|Jigglypuff}}'s [[Rest]], getting a Star KO means that the character will not [[respawn]] fast enough to [[punish]] the sleeping Jigglypuff, due to the length of the Star KO animation. However, if a character is instead Screen KO'd, this provides them with more time to potentially get a solid hit on the vulnerable Jigglypuff. The Screen KO's shorter duration can also influence the outcome of matches that have gone to a last [[stock]] situation. If both characters are KO'd off of the top at around the same time and one is Screen KO'd instead of Star KO'd, the Star KO'd player will win the match due to random chance and the lengthier animation.  

A [[Bonus points|bonus]] exists for getting Screen KO'd, Foresight, which grants the receiver 500 points for every time they are KO'd this way.

With strong knockback yells being scrapped and unused in ''Brawl'', characters now either use their regular pain yells or remain silent when they hit the screen.

In ''SSB4'', instead of using their tumbling animation, every character now uses a unique Screen KO animation depicting them flying towards the screen, hitting it face-first, then staying in place briefly before sliding down. Due to this new separate animation, several characters pose during their Screen KOs in a manner referencing their series, such as {{SSB4|Kirby}} reusing a pose from ''Kirby: Triple Deluxe'', {{SSB4|Cloud}} using a pose similar to his official render, and {{SSB4|Shulk}} hitting the screen with his back in order for the [[Monado]] to be visible. Characters who share the same base model tend to share the same Screen KO poses, such as {{SSB4|Ness}} and {{SSB4|Lucas}}. While ''Smash 4'' re-added strong knockback yells that were absent in ''Brawl'', Screen KO'd characters in ''SSB4'' no longer make any vocal sounds when they hit the screen, and instead, a comical "thud" sound effect is played.

As a direct result of the new Screen KO's "pause", Screen KOs now take a very slight amount of more time to resolve than a Star KO, which is seemingly a change made to not affecting gameplay as much compared to ''Melee'' or ''Brawl''. Furthermore, Screen KOs and Star KOs are both disabled during the [[Match timer#Final countdown timer|final five seconds of a match]] and [[Sudden Death]] — characters will simply create the usual colorful blast after crossing the blast line. Blast KOs can still occur even if the match has no [[Match timer|time limit]] or if it is in an early part of a [[time]]d match.

Several characters have different Screen KOs between both versions. The maximum amount of characters that can be Screen KO'd at one time is three. If the 3D slider is turned on in the ''Nintendo 3DS'' version, the stage's field of view will momentarily "flatten" during a Screen KO while the KO'd character appears at the forefront, slightly protruding from the screen.

In {{forwiiu}}, Screen KOs are disabled on [[Super Mario Maker]], [[Jungle Hijinxs]] (normal form only), [[Flat Zone X]], {{b|Duck Hunt|stage}}, [[Wii Fit Studio]], [[Pac-Land]], and [[Umbra Clock Tower]], and players instead are either Blast KO'd or Star KO'd on these stages. Screen KOs are available in all stages except Super Mario Maker and Umbra Clock Tower in {{for3ds}}.

Screen KOs retain their unique animations from ''Smash 4''. They once again complete faster than Star KOs, which will affect gameplay. For the first time in the series, one attack can cause [[Instant KO|instant]] Screen KOs, which is [[Giga Bowser Punch]], and the [[Beetle]] item will now always cause a Screen KO. At the end of the animation, the colored blast from a Blast KO now appears off the bottom blast line. However, there are still stages where Screen KOs can't occur. These stages in VS. mode are:

*{{SSB|Mushroom Kingdom}}

*[[WarioWare, Inc.]]

*[[75m]]

*In both ''Melee'' and ''Brawl'', it is possible to see a character about to hit the screen right before they are KO'd by pausing and then zooming out. This can be seen particularly in larger stages such as [[New Pork City]] and [[75m]]. This is also possible in ''Ultimate'', albeit zooming out makes the character disappear.

**Similarly in ''Wii U'', it's possible to see the white lines just when a character impacts the screen when pausing (though the character can't actually be seen). Unlike the trivia point above, this can be seen even in small stages.

*In ''SSB4'' and ''Ultimate'', [[Pit]] has two subtle Screen KO differences, depending on how his bow was last used: one with him holding his bow in his right hand, and the other with him holding the two separated parts of his bow as blades. This aspect is shared with [[Dark Pit]].

*In the Wii U version of ''SSB4'' and in ''Ultimate'', Mario, Kirby, Pikachu, and Dr. Mario use unique models during their Screen KO since their bodies are pressed flat as if hitting a glass pane; however, Mario and his clone Dr. Mario only have a model for their heads, while Kirby and Pikachu have their bodies.

**Kirby's model in this instance appears to reference ''{{s|wikirby|Kirby: Triple Deluxe}}'', which has a similar gimmick when Kirby is hit by certain attacks.

*In ''SSB4'', {{SSB4|Bowser}} and {{SSB4|Donkey Kong}} are the only characters to fall back when Screen KO'd, as all the other characters just slide off the screen. ''Ultimate'' later adds {{SSBU|King K. Rool}}. Notably, these characters are the [[weight|heaviest]] in the series.

**Bowser's Screen KO in ''SSB4'' and ''Ultimate'' may be a reference to the ending of ''Mario & Luigi: Superstar Saga'' where, after his airborne castle explodes, he's launched out of it, thereby "literally" breaking the fourth wall.

*Fighters KO'd with a Screen KO while under the effects of a [[Super Mushroom]] or [[Special Smash|Mega Smash]] may clip through the camera, making their models transparent. If this happens, the other side of the model will be invisible, showing the stage behind them.

*The instant KO from Giga Bowser Punch is the only instance where characters can be Screen KO'd without having to cross the upper blast line; instead, they are punched straight onto the screen.

*Notably, Bayonetta, Snake, and Incineroar show no actual emotion when Screen KO'd in ''Ultimate''.

*{{SSBU|Shulk}} and {{SSBU|Sephiroth}} are the only two characters in ''Ultimate'' to hit the screen with their back.

**{{SSBM|Bowser}} hits the screen with his back in ''Melee''.
