Oa is the planet at the center of the universe, home to the Guardians of the Universe and headquarters of the Green Lantern Corps.
History
The Guardians built the Manhunters on Oa, but soon decommissioned them.
Oa was seemingly destroyed by Amazo, but was actually sent to another dimension by it, claiming it was in its way as it was returning to Earth. At John Stewart's request, Amazo brought it back.
