Erron Black is a mercenary from Earthrealm, but in the service of Outworld. Depicted as a 19th-century gunfighter from the Old West, his backstory reveals that his body's aging was slowed by Shang Tsung in exchange for murdering an unidentified Earthrealm warrior. As a result, he utilizes 19th century weaponry. He serves Kotal Kahn in Mortal Kombat X, which puts him into conflict with Earthrealm's warriors. Mortal Kombat 11 features a past version of Erron Black who serves Shao Kahn, while his present counterpart assists Kitana in defeating Shao Kahn's forces. The character placed 10th in Den of Geek's rating of the series' 73 characters in 2015, the highest of any fighter not introduced in the first three games, which described him as "the Boba Fett of Mortal Kombat".
