storyline Batman went to the JLA headquarters and met with Booster Gold, Wonder Woman, and Superman. He told them Brother I was stolen, and what it could do (super-intelligent spy satellite created in response to his mind-wipe). He told them Blue Beetle was dead. He also clued them in on the real Checkmate, which had stolen Brother I.
Maxwell Lord was furious that Batman had Blue Beetle's goggles and knew it must have been an inside job. Lord initiated a hit on Overthrow - a Russian metahuman. An OMAC (One Man Army Corp) appeared and killed the man. As Sasha walked in, the computer told Lord an assassination attempt would be made on him. They had a meeting - both kings and queens, with their knights. The Black Queen's Knight (Midnight) pulled a gun on Lord, but he used mind control and had her kill both the White King and White Queen. Midnight would take the fall for the assassinations.
In Chicago, Sasha met Batman. Lord saw them kiss and sent OMACs to retrieve them.

Issue The OMAC Project #6
Subtitle Loss of Signal
Date November 2005
Writer(s) Greg Rucka
Artist(s) Jesus Saiz, Cliff Richards, Bob Wiacek
storyline The nanobot virus - what turned people into OMACs was in full swing. Sasha worked at a way to stop them without killing the hosts as Batman attempted to contact the league. Fastball and Firefly were some of the first casualties.
Sasha put a call out to all of the former Checkmate for help and explained the Black King - the person who perverted the organization - was dead. They immediately began getting response. Midnight contacted Batman on the two possible stops: a virus that would disable communication between Brother Eye and the nanobots, or an electromagnetic pulse big enough to destroy most of the life on earth. Batman said he'd handle it and cut communications. He called in the Green Lanterns - Hal and John. He gave them an EMP creator that the OMACs had originally wanted to steal when they got the Kryptonite - they didn't get it because it hadn't been delivered. Max knew Ted was getting it, but didn't know when. He had no use for the K since he already controlled Superman. The GLs took it to a remote location in the Sahara. They called in all the metas they could so to create a big enough target for all the OMACs to follow them.
Sasha spread the virus; Brother Eye shut down communications causing OMACs to revert to human. Batman's plan also worked, the EMP destroyed enough of the nanobots to revert the rest of the OMACs to human form. Somewhere around 200,000 OMACs were still under Brother Eye's control. Brother Eye broadcast a video of Wonder Woman killing Max Lord throughout the world.
