Manhunters 'Platinum'

The Manhunters were constructed by the Guardians of Oa billions of years ago as their first attempt to police the Universe. When the robots’ programming was corrupted by the renegade Oan, Krona, the units developed emotions—especially pride and arrogance—and mutinied. After they eradicated life in Sector 666, most Manhunters were scrapped, but many escaped and went into hiding.
