Endurance

Endurance is a special recurring match dating back to the first Mortal Kombat in which the player must fight more than one opponent alone.

Overview
Endurance matches are often typically reached near the end of the tournament. Unlike normal matches, the opponent uses two characters to fight you with, though you fight one at a time. Once the first opponent is defeated, the second takes their place immediately. Any damage taken is carried over to the next opponent, hence the term 'Endurance'. The player must defeat both kombatants to win the round. Endurance matches are only possible by computers though modes in future games allow a similar experience for the player

Mortal Kombat
After the Mirror Match is finished, the player must face off in three Endurance matches. The final match always takes place in Goro's Lair. As this battle goes on, occasional tremors and Goro's roar can be heard. After the match is finished, Goro immediately steps in, though the player this time has their health refilled

Ultimate Mortal Kombat 3
Endurance matches return in UMK3, now represented by E portraits in the Tournament Ladder and take place before the battle against Mortaro. Each color pertains to specific opponent sets, though chosen at random. In Shao Kahn's Lost Treasures, it's possible to select the Mega Endurance Kombat in which the player must face off against every secret character: Noob Saibot, Classic Sub-Zero, Human Smoke, Ermac and Mileena

Mortal Kombat 4
Endurance is no longer a match, but now a selectable mode featuring 3 different variations: the normal Endurance featuring 18 matches, Vs. Endurance where both players fight one another in endless matches until the other falls and Ultimate Endurance where the player confronts an endless onslaught of progressively harder foes.
