Kai Ro will be among the group with Micron, we probably need our stronger players to try and wreck the machine the infected are constructing and deal with Barda and Mr. Miracle. Superman will be guarding the Lantern's ring in the same control room where Brainiac is located and assimilating the technology. Batman, Aquagirl, Static, Warhawk, Starfire, and the Martian Manhunter are all presumably around the JL Watchtower somewhere.
