Ermac is a character of the Mortal Kombat series of Fighting Games, starting with Ultimate Mortal Kombat 3. He is known for speaking as if he is in a group, despite being a simple unit.
Fanon Ideas so Far
Ermac was created by the MK Team because of fan mythology. It was said that by overplaying the Sega version of Mortal Kombat with Scorpion, the screen would eventually flaw and flash an alert message on the screen. The message read "ERror MACro" and it would turn Scorpion's yellow outfit red. This was proven to be completely false. Despite repeated references that tried to inform the player that Ermac did not exist, they eventually decided to create him and include him in Ultimate Mortal Kombat 3. This actually refreshed some of the speculations regarding this rumor.
