Kruel KO's are a special kind of KO in All Star Smashers, based on the concept of the same name from Smash Bros. Lawl. To Kruel KO an opponent, you must have only one opponent left on the stage on his or her last stock with at least 120% damage, and KO him/her horizontally, upwards or downwards. You must have less than 120% damage to perform a Kruel KO.
Kruel KO's on Stages
If you Kruel KO an opponent in Talk Room, the opponent will be seen defeated in a massive explosion outside the building, killing him/her. Then, the White Houserz version of Adamp5104 shows up, tragically saying "I'm sad." about the character who died.
