OMAC units became a threat after Batman™ constructed the artificially-intelligent Brother Eye satellite to monitor metahuman behavior. Corruption by Maxwell Lord caused Brother Eye to infect more than a million human agents with a nanotech virus and initiate a sweeping campaign against metahumans. Although Batman destroyed his creation during the Infinite Crisis, the OMAC Project lived on in the form of its single surviving agent, Michael Costner.
