The OMAC Project
The OMACs are cyborgs, human bodies transformed by a virus into living machines to assassinate any and all beings with superpowers. The virus was created from Brainiac 13's nanotechnology, which had been acquired by the U.S. Department of Defense and Lexcorp, and was then secretly introduced into general vaccine supplies. The OMACs are featured in the mini-series The OMAC Project, one of several preludes to the series Infinite Crisis.
Brother MK I
The new OMACs are controlled by Brother MK I, a satellite that was created by Batman, programmed by Buddy Blank, and designed to gather data on metahumans. Batman had grown distrustful of metahumans after remembering that the Justice League altered his memories following an altercation with Doctor Light in Identity Crisis. Alexander Luthor Jr. later gives the satellite sentience as part of his plans. Maxwell Lord, promoted to the top rank of Checkmate, subverts the original mission of the Brother MK I satellite by inculcating a fear and suspicion of all metahumans.[3]
Brother Eye
When Maxwell Lord brainwashes Superman to kill Batman, Wonder Woman kills Lord to free Superman from his control. Brother MK I, rechristening itself Brother Eye, initiates the "KingIsDead" protocol, which was specifically designed to be used in the event of Lord's death. It orders all of the OMACs (numbering more than one million) to attack and kill every metahuman on Earth and destroy Checkmate.[4] A group superhero effort stops the attack, freeing most of the OMAC hosts from their nanotech forms and reducing the number of remaining OMACs to roughly 200,000.

Truth and Justice
The satellite broadcast footage of Wonder Woman executing Maxwell Lord, preceded by the word MURDER, is spread to media outlets all over the world, destroying her reputation. After this, Brother Eye initiates the final protocol, "Truth and Justice", by having all the remaining OMACs invade and attack Wonder Woman's homeland, Themyscira, to wipe out all of the Amazons.
It is revealed that Alexander Luthor Jr. wrested control of Brother Eye away from Batman. He used it to program his multiverse tuning fork and redirect its energy to where he needed it as part of his attempt to re-create Earth-Two, and in turn, a perfect Earth. Brother Eye aids Luthor by remapping out the multiverse and helping to guard the tuning fork with its OMACs, reasoning that it would eliminate the need for heroes like those who Batman had created it to monitor by aiding in the creation of a perfect Earth.

Downfall of Brother Eye
Batman leads Hal Jordan, John Stewart, Green Arrow, Mister Terrific, Black Lightning, Black Canary, Blue Beetle, Metamorpho, Booster Gold, and Sasha Bordeaux to Earth's orbit using intel from Booster Gold and Ted Kord's spaceship. Blue Beetle's scarab allows him to find and reveal Brother Eye by negating its vibrational frequency. Brother Eye sends the OMACs and the two groups clash.
With the two Green Lanterns fighting off most of the OMACs and Brother Eye's defenses, the heroes' ship crashes into Brother Eye. Sasha Bordeaux, linked to Oracle, uploads a series of viruses into Brother Eye's system. Black Lightning and Mr. Terrific go to the memory banks so that Black Lightning fries as much circuitry as possible while Mr. Terrific, invisible to machines and electronics, delivers the fatal blow by knocking Brother Eye out of orbit using its orbital thrusters. Brother Eye tries to download its system into Bordeaux as a means of self-preservation, but Bordeaux destroys the satellite, freeing herself from the nanobots infecting her.
Michael Costner
Brother Eye was not fully destroyed and lies in a NORAD facility. Michael Costner is the last OMAC unit, kept as emergency backup, and Brother Eye calls to him.
This Brother Eye has corrupted programming and now believes all humans need to be subjugated or exterminated whether metahuman or not. The 2006 limited series OMAC follows Michael Costner as Brother Eye attempts to make him rebuild it. Costner regains control of his body and destroys Brother Eye again, although a small part of it is still active.
Countdown to Final Crisis
A portion of Brother Eye is retrieved and rebuilt by Buddy Blank. This portion meets with the time-traveling Karate Kid who is seeking a cure for Morticoccus, a 31st-century illness that evolved from the OMAC virus. Announcing that "the Great Disaster has come to me", Brother Eye directs him to Blüdhaven. Soon after, it reactivates its offensive protocols and assimilates the hangar it is being held in, turning the people within the hangar into new OMAC cyborgs. It then travels to the ruins of Blüdhaven and assimilates the city's infrastructure and the people within it using the Atomic Knights and Firestorm as power sources.[5][6][7] Later, it activates a Boom Tube and travels to Apokolips, where it assimilates the planet and attempts to obtain the Morticoccus virus from Karate Kid.[8] Brother Eye is forced to flee Apokolips after the Pied Piper attacks it.
Batman and the Outsiders
A modified OMAC is shown as a part of the new Outsiders team in the 2008 Batman and the Outsiders series.
When a team from the Justice League attempts to seize a partially active OMAC, a leftover from The OMAC Project events, Batman takes the opportunity to reclaim it for himself—having Francine Langstrom create a clever forgery to leave in care of the League.
The OMAC, renamed ReMAC, is a husk devoid of any personal identity, with Langstrom being unable to uncover who it was before being turned into an OMAC. This complete lack of personality makes ReMAC the perfect infiltrator, using its advanced shapeshifting abilities and unquestioning obedience for the Outsiders' cause. Batman creates a telepresence system turning ReMAC into an advanced drone for Langstrom's assistant Salah Miandad, enabling operation from the Outsiders HQ, the Batcave, or other secret locations.
While testing a new neural interface to control the former OMAC, Miandad is knocked into a coma. His mind comes to reside in ReMAC, supplanting the missing personality of the drone. Due to the machinations of Simon Hurt, ReMAC is fed a malicious self-destruct code that destroys it, killing Miandad.[10]
Final Crisis
In Final Crisis, Darkseid and his prophets take new forms as humans on Earth after mass-distributing the Anti-Life Equation around the world. Mister Terrific and Checkmate work to mount a resistance against Darkseid, but seemingly do not have the means to do it. Sitting in despair in a Checkmate stronghold, Snapper Carr gives Mister Terrific an idea. Using Sasha Bordeaux to make contact with Brother Eye, he convinces the A.I. to help them, explaining that it will be destroyed if Darkseid captures the world.
Realizing this, Brother Eye accepts Mister Terrific's terms and reveals that there are still millions of people infected with OMAC technology. These people, now mindless drones of Darkseid, are overwritten by Brother Eye and become OMAC soldiers under the command of Mister Terrific. This gives Checkmate and him the means to resist Darkseid. Brother Eye prepares to leave the doomed Earth with his OMACs and start a new society in another universe.
Generation Lost
In Justice League: Generation Lost, the resurrected Maxwell Lord controls the squad of OMACs attacking Jaime Reyes's home and his family.[11] After Lord escapes from the JLI, Booster Gold's robot Skeets informs the JLI that he has the locations of the four formerly-dormant Checkmate cells which he had placed inside robotics laboratories that Lord has been in contact with.[12] The JLI travel to Chicago beneath the hidden robotics laboratory and learns that the OMAC variants were pure robots that are human/machine synthesis of the originals.[13]
Lord sends his newest OMAC known as OMAC Prime, to which he had given both sentience and his voice, to attack Diana and the JLI.[14] This new OMAC could assimilate the abilities of metahumans, initially overwhelming the heroes it fought. During the final battle, Prime takes Blue Beetle's power, causing it to become nearly unstoppable, but Blue Beetle mentions to OMAC Prime that it cannot control the Scarab's power. Blue Beetle uses this to paralyze Prime with crippling system failures before attacking and destroying it.[15]
Kevin Kho
In 2011, The New 52 rebooted the DC universe. A Cambodian-American man named Kevin Kho is introduced as the new O.M.A.C. (One-Machine Attack Construct) and had worked as a genetic researcher at Project Cadmus.[16] Maxwell Lord is revealed to have had a hand in Kho's transformation in addition to using New Genesis technology.[17][18] O.M.A.C. starred in a self-titled series that was cancelled after eight issues due to DC's introduction of a "Second Wave" of new titles.
During the "Forever Evil" storyline, the Crime Syndicate of America captures Kevin Kho, intending to use him as a weapon.[19] Harley Quinn, who is working for the
