OMAC

OMAC (Omni Mind and Community)s are cyborgs who take over human bodies via a virus (created from Brainiac-13-derived nanotechnology acquired by the U.S. Department of Defense and Lexcorp, which was then secretly introduced into general vaccine supplies) in order to assassinate any and all beings with superpowers. They still retain OMAC's familiar crest and Brother Eye symbol on their chest.

The new OMACs are controlled by the Brother I satellite. Brother I was created by the Batman to keep an eye on all metahumans, both villain and hero, after he grew distrustful over the Justice League's mindwiping. Alexander Luthor later gave the satellite sentience as part of his plans, and Maxwell Lord subverted the original mission of the Brother I satellite by inculcating a fear and suspicion of all metahumans when he rose to the top rank of the government agency Checkmate.

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.

It was revealed that Alexander Luthor was the one who wrested control of Brother Eye away from Batman. He used it to calculate the coordinates of where the multiverse Tower would concentrate its energy as part of his attempt to re-create Earth-Two. Brother Eye continues to aid Alex Luthor and helps guard the tower.

Abilities
Metahuman Database: An OMAC unit has archives on almost every metahuman on file.

Power Simulation: It can simulate the powers of a variety of superheroes and supervillains in order to target its opponent's weaknesses. Among the powers displayed were the ability to fly, shoot fire, needles of artificial cellulose (against Alan Scott), dispense flame-retarding foam, and fire various energy beams from its eyes and hands, with caustic, concussive, or blinding effects. Nano-morph: In addition, the OMAC unit can morph its extremities into blades and pincers. It is also able to simulate Shazam's lightning and force Mary Marvel to revert to her human form. It can disable the Eradicator effortlessly.

Weakness
T-Mask Blinded: OMACS are very vulnerable to Mr. Terrific, as he cannot be detected by technology.

Human: The only weakness an OMAC has are that they are human, beneath their shells (which was meant as a deterrent for heroes from using lethal force against them).

Threat Assessment Countermeasure: Other than that, the OMACs are dependent on their assessment of individual heroes. When fighting multiple opponents, they require a few seconds to adapt their countermeasures for each hero. Atom Smasher was able to stop an OMAC attacking the JSA, by stomping it before it could assess his threat level.
