- Mortal Kombat X: "Erron Black's exact origins are unknown. Born on Earth, he somehow found himself in Outworld. There he spent years wandering its vast territories, selling his amazing weaponry skills to local warlords. Now in the employ of the emperor, Kotal Kahn, Black shows no inclination to return to Earthrealm--or aid them in their present struggles."
Erron Black was present during Sonya Blade's interrogation of Kotal Kahn. During this interrogation, Kotal repeatedly tries to convince Sonya and the Special Forces to ally themselves with him and the rest of Outworld. Later on, D'Vorah grows impatient and breaks from her chains to attack Sonya but stops when she sees Sonya pull her gun out. Before the situation escalates any further, Kotal Kahn breaks his chains (as well as Erron's) and shouts at them both, claiming this was no place for combat. During the whole exchange, Erron Black remains silent and doesn't act.
Sonya then pins D'Vorah on the ground and threatens to shoot her if Kotal takes one more step. Angered and provoked, Kotal tries to attack but is interrupted when Raiden appears and shocks everyone within the room. After Raiden gets everybody to stop, Erron helps his emperor up as Kotal warns them that Earthrealm will experience Outworld's pain then escapes via Portal Stone, with Erron and D'Vorah by his side. Later on, it was revealed that Erron assisted Black Dragon members Jarek and Tasia in capturing Cassie Cage and Jacqui Briggs.
Erron appears again observing Kotal Kahn alongside his trusted warriors D'Vorah and Reptile as Kotal Kahn makes his speech to the citizens of Outworld. Erron, alongside D'Vorah and Reptile, can be later seen following Kotal Kahn and his father Kotal K'etz back into the palace after Kotal announces his father's mission to find Goro and Mileena in the Golden Desert.
Erron Black is revealed to be the Black Dragon's liaison for Outworld and orchestrated the kidnapping of Cassie Cage and Jacqui Briggs without acting on Kotal Kahn's orders. Black rendezvous with Kano and his Black Dragon soldiers who have Cassie and Jacqui and demands Kano not blast them his optic beams anymore, as well as belaying Kano's orders to mutilate the girls if they try to escape again, citing they're worth more intact.
After Kano explains how he got his new implant, Erron notices they are no longer alone, and moments later two of their soldiers holding Cassie and Jacqui's unconscious bodies are killed, and Red Dragon forces led by Mavado make themselves known, demanding the girls. Black draws his pistols as Mavado and Kano face each other.
Erron Black made it clear he would not bargain with Mavado and that the girls belonged to Kotal Kahn. After Kano killed one of Mavado's soldiers, an all out brawl erupted between the two factions, with Erron Black firing both of his pistols into Mavado's forces. Black quickly realizes that the Black Dragons are outnumbered and after spotting Cassie and Jacqui attempting to run, he frees them from their bonds, promising that he can get them all out of there, but if they want to live they must fight.
Unfortunately for Erron, Jacqui decides to attack him instead, sucker punching him across the jaw and beating him down to the ground, despite Erron trying to reason with her. Kano eventually punches Jacqui off of Black, telling him they need to fall back and asks for the Portal Stone. Erron tells him which pocket the stone is in and after telling Kano that they still need to get the girls, Kano chooses instead to mock Erron for trying to save people instead of exploiting them, saying that is the reason he could never be a Black Dragon.
With that, Kano flees through a portal, leaving Erron cursing at him as he vanishes. Mavado mocks Erron for trusting Kano and then cuts the gunslinger's chest with both of his hook swords in a spray of blood, badly wounding Black. Erron survives however, and after Mavado is killed by Cassie and Jacqui, he is bound by to a tree top by the surviving Red Dragon forces, and is told to pass along a message to whoever comes searching for them.
Later, Black is found by Johnny Cage as he, Sonya Blade and a Special Forces team are led into Outworld's jungles by D'Vorah and Reptile. After being cut down and telling them of the battle between the Dragon factions, Erron Black tells them the message he was to pass along: They were invited to Shang Tsung's Island, where Reiko's spiritual adviser, Havik, is holding the girls.
A still wounded Erron Black pleads before Kotal Kahn that he was only trying to serve him, and begs for his emperor's mercy. Kotal Kahn briefly considers killing Black before harshly reprimanding Erron and telling him his actions almost caused another war that Outworld cannot afford. Kotal then orders Reptile and D'Vorah to take him back to the dungeon.
Erron remains in the dungeon for some time until D'Vorah returns to Outworld from Shang Tsung's Island, needing reinforcements. She frees Erron and takes him with her alongside Reptile, Ferra and Torr, Sheeva, and Kintaro. When they arrive in Shang Tsung's Palace, Erron shoots Shinnok's amulet from Havik's hand, making it clear that was only a warning shot.
As Havik and his Blood Code enslaved champions confront D'Vorah and her forces, D'Vorah asks the gunslinger if he is ready for redemption. Erron simply tells her to tell him who to fight, and after D'Vorah orders him to keep Raiden occupied, and even die to do so, an annoyed Erron comments that he believed this to be a rescue mission. Opening fire on Raiden with both of his revolvers, Black states, "Feels more like a suicide squad!"
Erron continues to fire at Raiden, but is soon overwhelmed by the thunder god, who electrocutes the gunslinger with bolts of red lightning. Raiden is soon freed from Havik's control and ceases his attack on Erron, who weakly asks if that's all the god has before collapsing unconscious.
Erron Black is seen leading Kotal Kahn's convoy through Outworld with Ermac. When Mileena's army ambushed the convoy, Erron is seen fighting the Tarkatans with his fellow teammates. After Kotal Kahn incapacitates Rain, Erron is sent to finish him. Just as he is about to pull the trigger, Mileena throws her sai into his hand, knocking his revolver out, Rain then quickly retreats as Mileena fights Kotal Kahn.
Later, Erron "greets" Cassie Cage, Jacqui Briggs, Takeda Takahashi and Kung Jin as they arrive in Outworld seeking Kotal Kahn to confirm what Li Mei reported to Earthrealm; Mileena obliterating entire villages with Shinnok's Amulet. When Cassie tries to show him Raiden's Blessing, Erron doesn't believe them claiming that he could get a fake one in the marketplace. However, Jin convinces Erron that he'd get punished if they are who they say they are, and could possibly get paid more if he does bring the four to Kotal. Erron agrees and starts to bring them to him.
However, while the group passes a large gathering of Outworlders preparing for the public execution of a thief, Jin gets upset at the overkill of the punishment. He ignores Erron's warning and goes to free the thief. Erron begins Kombat with him, but ultimately fails to stop Jin. After Jin and his teammates incapacitate the opposing force, D'Vorah brings Kotal Kahn who gets upset when it is revealed to him that Mileena is in possession of Shinnok's Amulet. After Jin defeats Kotal in kombat, Kotal Kahn and his associates are indebted to Earthrealm to work together to stop Mileena.
After D'Vorah's betrayal of Kotal Kahn, where she kills two guards and steals Shinnok's Amulet for Quan Chi, Erron, Reptile and Ermac discovers the bodies and deduce that it was D'Vorah's handiwork. When the Earthrealmers escape their cells, they run into the Outworlders and try to stay silent but quickly get detected by Reptile. Erron has a brief fight with Takeda, but is defeated.
Erron, Reptile, and Ermac are present with their meeting with Kotal Kahn, informing him of D'Vorah's betrayal and apparent allegiance to Earthrealm. Kotal Kahn, saddened and angered by her betrayal, orders his men to prepare the armies with the intention of invading Earthrealm and taking the amulet back.
Shortly after Shinnok corrupts the Jinsei, Erron and his associates enter Earthrealm and run into Cassie and her team, who run off into the woods. The team set up an ambush on Kotal's forces and take out a majority of the fighters, however they are soon surrounded by the rest of Kotal's army. When Jacqui informs Kotal of Shinnok's presence, Kotal says that Earthrealm is doomed and decides to kill the Earthrealmers, hoping to appease Shinnok and buy time to build up Outworld's defenses. Just as the army, including Erron, are about to execute the team, Sub-Zero and his clan attack the forces allowing the Earthrealmers to escape. Erron Black and the rest of the Outworlders' fate is unknown after this, but it is likely that they were driven back to Outworld.
- Mortal Kombat X: "Nearly 150 years ago, Erron Black had been hired by Shang Tsung to assassinate an Earthrealm warrior. In return, Shang had slowed Black's aging process. He could therefore afford to be patient. If an employer wanted someone dead, they would be in time. A team of young Earthrealm warriors had caused Erron Black's current employer, Kotal Kahn, much inconvenience. With the patience of a viper, Black eliminated them all."
