|Bio: While on his way to return to earth, Amazo ran through Oa, the
headquarters and home planet of the Green Lanterns. Though
thought to have been destroyed, Oa was simply "moved" because it
was in Amazo's way.
The leader of the Corp seems to be none other than Kyle Rayner,
the young rookie from earth. Though John Stewart has long since
replaced Kyle as the head Lantern for Earth, Rayner has
expressed feelings of being homesick for his original home.
