As a small example, suppose b = 4, C = 0011 2, and k 0 = E k(0) = 0101 2. Then k 1 = 1010 2 and k 2 = 0100 ⊕ 0011 = 0111 2. The OMACs and Brother Eye would have appeared in the abandoned project Justice League: Mortal as underlings of Maxwell Lord and Talia.

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 that leads up to the Infinite Crisis series. The OMACs (One Man Army Corps) appear in Blue Beetle as collapsible powered armors with brain–computer interfaces developed by Kord Industries, with first test subject Ignacio Carapax (portrayed by Raoul Trujillo) as a notable user. [37]ReMAC, the OMAC possessed by the Outsiders, has the same powers and abilities of a regular OMAC. He greatly differs in his physical makeup, being red in color and with a more human-like face even in his armored form. Goals for the standards include improving efficiency, the ability to move operators from machine to machine with less training and reducing downtime.

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. and firing various energy beams from its facial/chest eye and hands with caustic, concussive, or blinding effects. In addition, the OMAC unit can metamorphose their nanobionic forms into various shapes and sizes; e.i. being able to change & 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).A modified OMAC is shown as a part of the new Outsiders team in the 2008 Batman and the Outsiders series. OMAC has almost 60 member companies in North America, Europe, Latin America and Asia. The foundation of OMAC’s success is the collective strength of its members and their commitment to advance manufacturing automation and efficiency. Knowledge, experience and financial support drive OMAC initiatives that make a difference. Brother Eye and the OMAC Project appear in DC Universe Online, with the former voiced by Ken Thomas. Brainiac uses Brother Eye to take over Earth via its OMAC virus, a Defective OMAC, OMAC Drones, OMAC MK II, OMAC Nanosyths, OMAC Sigmas, OMAC Units, OMAC Delta, and an OMAC Incinerator.

In Final Crisis, Darkseid and his prophets from Apokolips have taken new forms as humans on Earth after mass-distributing the Anti-Life Equation around the world. Batman has been captured; Superman is on a journey in the multiverse; and Wonder Woman has become a Female Fury. With most of the world's population under the influence of the equation, they are effectively under Darkseid's control seemingly making him the ruler of the Earth. Brother Eye appears in Injustice 2, voiced by David Loefell. This version is a communications hub linking every satellite and server on Earth designed to warn of impending crime created by Batman after the toppling of Superman's Regime and is based in a new Batcave built in an old Gotham City subway system. Additionally, Brother Eye serves as the game's announcer and its satellite interface the main menu. In the game's "Multiverse Mode", Brother Eye is stated to have Source energy scanners, enabling it to search for threats across the multiverse. Motamayor, Rafael (June 14, 2021).

Retrieved June 14, 2021.In Batman #700 (June 2010) in a vignette within the issue, Damian Wayne as Batman is shown having succeeded at what his father had failed to do: regaining control of Brother Eye. [21] Kevin Kho [ edit ] The OMACs appear in the My Adventures with Superman episode "My Adventures with Mad Science" as robotic foot soldiers for Task Force X. During the Final Crisis events when all seems lost, Lord (Brother) Eye prepares to leave the doomed Earth with his OMACs and the people of Command-D, the bunker underneath Blüdhaven, and start a new society on another Earth in another universe. To this end, he asks Renee Montoya to serve as the head of a to-be-founded Global Peacekeeping Agency, her faceless appearance as the Question being an allusion to the faceless agents of the GPA from the original OMAC series. 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 battled for survival alongside the future versions of the Justice League, but they all are eventually contaminated by a new version of OMACs and one by one become OMACs themselves. Captain Atom is eventually returned to the present, but not before Batman ( Damian Wayne) tells him how to stop Max's ultimate plans. [16] The plan works, and Brother Eye is deactivated. All of the remaining activated OMACs shut down, releasing their hosts. As all of the other heroes evacuate Brother Eye as it begins falling out of orbit to Earth, falling apart in the process, it tries to take Batman down with it, telling him he can never trust the costumed heroes again after what they did to him. Batman, however, says he will take his chances, and accepts Hal Jordan's aid in getting to safety.
