A Kruel KO is a new stage mechanic that, while specific to execute, ends a match in an awesome or funny way. The requirements of pulling off a Kruel KO are:
- The opponent must be at 120%+ and on their last stock (I guess that means this can only be pulled off on Stock matches).
- The KO must be the last in the match, i.e. the game-finishing KO
- The opponent must be KO'd either upwards, downwards or sideways, depending on the stage.
- You must be at less than 120% damage.
