Screen KO

A Screen KO is a type of KO in the Super Smash Bros. series and Super Smash Flash 2 where a character falls and crashes into the screen while making a sound when they're sent flying above the blast line. Unlike in the main Smash games up until Super Smash Bros. for Nintendo 3DS and Wii U, characters normally hit the screen with their back. In SSF2. characters hit the screen with their front and make facial expressions. The screen will also crack, adding to the effect that the player is breaking the camera. Unlike in the main Smash games, only one character can be Screen KO'd at a time, any other upper blast line KOs will be Star KOs until the Screen KO is finished.

There is a fair bit of controversy surrounding the idea that, since the choice of Star KO and Screen KO is random (50-50% of chances for both), two players may end up being KO'd at different times even though they hit the top blast line at the same time. If both players are on their last stock, this can determine the match.
