Main article: 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 that leads up to the Infinite Crisis series.

Brother MK I

The new OMACs are controlled by the Brother MK I satellite. 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.[1] Its sole purpose was to gather data on all metahumans, both villain and hero. Batman had grown distrustful of metahumans after discovering that the Justice League altered his memories following an altercation with Doctor Light in Identity Crisis. Alexander Luthor, Jr. later gave the satellite sentience as part of his plans.[clarification needed] 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. The first OMAC test subject was renamed "Buddy Blank", after the scientist who programmed the satellite.[2]

The OMACs' history may be more recent than Brother MK I's itself. Equus and Pilate, formerly featured in Superman: For Tomorrow, are later denounced as former iterations of the OMAC concept. In JLA: Classified an all mechanical OMAC is an enemy of the Metal Men. Since then, the design has improved to the current form, with little to no changes to the base model.[clarification needed]
Brother Eye

When Maxwell Lord brainwashed Superman to kill Batman, Wonder Woman, and possibly the rest of the JLA, Wonder Woman broke Lord's neck to free Superman from his control. Because Lord proffered this solution while held by her Lasso of Truth, Diana believed this was the only course of action possible; she was fiercely criticized from many quarters.

Brother MK I, rechristening itself Brother Eye, initiated the "KingIsDead" protocol. 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. 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. These measures effectively freed the majority of the OMAC hosts from their nanotech forms and reduced the number of OMACs to roughly 200,000."
