Breach was an ancient warrior. He lived his life deffending Outworld from evil while he could, until Shao Kahn, Shang Tsung and many other evils took over. Breach was angered that Shao Kahn had murdered alll of Breach's allies, and took it upon himself to murder Shao Kahn, despite his oath not to kill. He was defeated and exiled away in The Flesh Pits.
Mortal Kombat: RevolutionWhen Shao Kahn's armies stormed the Earthrealm, they unleashed all living things from the Flesh Pits to attack Earthrealm. This army included Breach. Breach attacked the Washington monument but was attacked by the government. Raiden saw the Earthrealms military failing and struck Breach with lightning, which only made the creature grow. Breach tried stabbing Raiden with his arm-blade, but Raiden dodged it and blew up the monument, causing a chunk of it to go flying and strike Breach in the head. The creature fell down into the water below and moaned in pain. Later, inside the Statue of Liberty, Shao Kahn has all the Flesh Pit creatures gathered as Kahn stands across from a defeated Liu Kang chained to the wall. When the creature looks at Raiden flying in the sky, Raiden reminds him of all the innocent men Shao Kahn killed. The creature had a flash-back at his past life, and went into a fit of rage. Before Kahn can kill Liu Kang, Breach's arm-blade reached into the statue and stabbed Kahn in the stomach. He took out his arm-blade and saw Shao Kahn impaled on it. He smashed Kahn's gutted body to the ground and growled. After killing Shao Kahn, Raiden sent Breach back to the Outworld to once again live in peace.

When Zod and Darkseid entered the Mortal Kombat Universe, they met Breach. They offered Breach the chance to rule Outworld, but he declined. Breach's DC Universe counterpart is Deimos. After being captured by Zod, he was brain-washed and helped Zod and Darkseid revive Shao-Kahn. After this mission was over, they were about to "expose" of him, when Sub-Zero and Kitana rescued him. Breach joined the 2 in tracking down Zod, but they were attacked by Killer Croc whom tried eating Beach alive. Breach constantly tried to stab Croc but was defeated and dragged into Croc's under-ground lair while the others were distracted by Shokans. The 2 finally defeated the Shokans and went underground to find Breach. Breach was seen surrounded by baby Alligators, and then Croc noticed them. Croc charged at Sub-Zero and Kitana, but was frozen by Sub-Zero and smashed by Kitana. They woke up Breach and helped him escape. Later, along with Nightwing, Scorpia, Tremor and The Atom, he is seen watching Taven battle Mammoth in an arena.
