A No KO Custom Stage is one confined by objects which cannot be passed through, where it is generally impossible to be KO'd or SD. These types of stages provide a different twist on the normal setup, as players fight continuously in an inescapable area, without re-spawning and with high damage percentages. They would generally only be used for matches with various externally generated goals, such as being the first to reach a certain amount of damage, or having the least damage at the end of a time match, and are also conducive to the more traditional Stamina mode. A No KO stage might also be used simply for sparring without the need for recovery.
