The OMACs (/ˈoʊmæks/; Omni Mind And Community, originally Observational Metahuman Activity Construct and alternatively One Man Army Corps.

The OMAC reimagined as collapsible powered armor with brain–computer interfaces appeared in the 2023 live-action film Blue Beetle, set in the DC Extended Universe.

Brother MK I was created by Batman and programmed by Pseudopersons, Inc., scientist Buddy Blank, who in this retelling of the story is a partner of Wayne Industries.

Batman had grown distrustful of metahumans after remembering that the Justice League altered his memories following an altercation with Doctor Light in Identity Crisis.

Maxwell Lord, recently promoted to the top rank of Checkmate, subverted the original mission of the Brother MK I satellite by inculcating a fear and suspicion of all metahumans.

Specifically designed to be used in the event of Lord's death, it ordered all of the OMACs (all 1,373,462 of them) to attack and kill all the metahumans on Earth and destroy Checkmate.

[6] A group superhero effort stopped the attack, using an EMP blast as well as a "Shut Down" command given by Sasha Bordeaux, who had become a third-generation cyborg linked to Brother Eye, now designated Blacknight 1.

In response, the satellite broadcast footage of Wonder Woman executing Maxwell Lord, preceded by the word MURDER, to media outlets all over the world, destroying her reputation.

After this, Brother Eye initiated the final protocol, "Truth and Justice", by having all the remaining OMACs invade and attack her homeland, Themyscira, to wipe out all of the Amazons.

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.

Batman leads a collection of superheroes, consisting of: 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's hidden location above Earth by negating its vibrational frequency.

Sasha, linked to Oracle, goes to upload every computer virus on Earth into Brother Eye's system as well as trying to prevent the artificial gravity from shutting down.

[7][8][9] 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, who has also been led there.

This complete lack of personality makes ReMAC the perfect infiltrator, using its advanced shapeshifting abilities and its unquestioning obedience for the Outsiders' sake.

Realizing this, Brother Eye accepts Mister Terrific's terms and reveals that there are still millions of people infected with OMAC nanotech.

In Justice League: Generation Lost, the resurrected Maxwell Lord controls the squad of OMACs attacking Jaime Reyes's home and his family.

[15] When Captain Atom absorbs the energy from Magog's spear, he is propelled forward through time 112 years in the future, where Max, while long dead, has plunged humanity into a massive metahuman war that is ruled by OMACs.

Captain Atom is eventually returned to the present, but not before Batman (Damian Wayne) tells him how to stop Max's ultimate plans.

[16] Afterward, Max gains new mental powers that can allow him to transform his targets into cadaver Black Lanterns, and then into OMACs after being fully restored to life.

[28] OMAC is fighting King Shark and Kamo while Amanda Waller attempts to activate Belle Reve's failsafe through the Thinker's computer.

Having killed Kamo, OMAC is able to defeat Power Girl, Steel, Unknown Soldier, and King Shark and heads further into Belle Reve.

An OMAC unit has access to archives on almost every metahuman on file, and can simulate countermeasures to the powers of a variety of superheroes and supervillains for the purpose of targeting the weaknesses of an opponent.

Among the many inbuilt powers an OMAC drone possesses include flight, enhanced modular physicals pertaining to strength, speed, agility, reflexes, stamina, etc.

being able to change and alter extremities, its limbs into pincers and razor blades or even self generated cannonry, recombine upon and atop of one another to take on gigantic proportions as well as interface with technology using onboard micromachinery (regularly used amongst one another as a hive mind collective).

Said drones can also repurpose their microtech towards disabling and simulating the advanced technological capacities of other innovative creations, like the protective shielding of Themyscira.

Such as shooting fire, project needles of artificial cellulose (against Alan Scott; an approximation of his weakness to wood), dispense flame-retarding foam, even once simulating Shazam's lightning power forcing Mary Marvel to revert to her human form.

A very powerful and extremely deadly new class of O.M.A.C's were designed and employed by Maxwell Lord using the various resources of Checkmate, Project's Cadmus and M, the Metal Men responsometer tech, Amazo's absorption cell engineering and the xenomachinery of a Reach Scarab to fashion an all robotic legion of automatons which were easier to OMACtivate and conduct their motions while using the JLI to search out his ultimate goal.

A type of super android that could assess and exploit weaknesses, as well as implement psychological warfare using Max Lord's vocal patterns to offset his adversaries.

Unlike other O.M.A.C's, Prime had the unique ability to mimic and combine the meta-abilities and utilities of other super types into itself, steadily making it stronger during battle through the acquisition of new powers and technology assimilated into itself via observational stimulus.
