Star and Screen KOs

A Star KO (星バースト) and a Screen KO (手前やられ) are special types of KO in the Super Smash Bros. series. A Star KO occurs whenever a character is knocked beyond the upper blast line (the top of the screen). They will be seen flying into the background, often uttering a scream before they disappear into a star and then respawn. It is a considerably long "death", and there is an equal chance of a Screen KO happening instead, wherein a character will be thrown into the camera before slipping off the screen and respawning. Certain attacks and enemies, particularly in single-player modes will not trigger Star or Screen KOs if the player is knocked above the upper blast line.

Samus and Dark Samus both utter the same mechanical "scream" if Star KO'd; Dark Samus is the only Echo Fighter with this trait. Zero Suit Samus screams vocally, while Ridley utters a dragon screech. Screen KOs are considerably rarer to occur than Star KOs in all games except Super Smash Bros. for Nintendo 3DS and Wii U, and the Nintendo 3DS version in particular. On Flat Zone in Super Smash Bros. Melee, Samus will hit the screen in her tumbling animation if she is Screen KO'd.
