Oa is a fictional planet located at the center of the DC Comics Universe in Sector 0.

History

One of the oldest planets, Oa serves as the home and headquarters to a race of blue-skinned powerful humanoids who have dubbed themselves the Guardians of the Universe who administer the Green Lantern Corps. According to the story "Heart of A Star" in the Sandman: Endless Nights graphic novel, Oa's star is called Sto-Oa (the Light of Oa) by the children of the planet's inhabitants. Its location has been firmly established by numerous references in Green Lantern comics over the years.

Oa's history is not clear; according to some stories, the Guardians originated in a planet called Maltus. These evolved Maltusians later moved to Oa and named themselves Oans. Oa became a convenient base of operations. Other stories had the Oans living there from the beginning.

Oa appears to be mainly a desert-like, lifeless planet. The main feature is the Guardian's city which includes, among other things, the Main Power Battery that is charged by the Guardians with their own unique green energy. The Battery then broadcasts this energy to the personal Power Batteries of all Green Lanterns. The Green Lantern Hal Jordan, under the influence of the evil entity Parallax, killed all but one of the Guardians and most of the Corps before draining the battery of its energy. The planet was later destroyed during a battle between Jordan and his successor, Green Lantern Kyle Rayner.

The planet was reformed sometime later by Jordan's old friend and associate Tom Kalmaku in the graphic novel Legacy: The Last Will and Testament of Hal Jordan. The Central Power Battery was later recharged and the Guardians resurrected shortly thereafter by Kyle Rayner after he spent some time as the near-omnipotent "Ion".

After attacks by Superboy-Prime and the Spider Guild, the Guardians refortified Oa by creating a planetwide armour and defensive system to prevent successful attacks against them. The full capability of the new systems are still unknown. They were not however able to prevent an assault by the Sinesto corps. Afterward, the Gorps boubled its defenses.
