Oa is the secondary homeworld to the Guardians of the Universe, also known as the Oans. Originating on the planet Maltus, (which in the previous continuity is severely overpopulated in the present time), the Oans, then known as the Maltusians, conducted a variety of experiments on life, forces, and the wider universe. One of their number however, a scientist named Krona, conducted a long forbidden experiment to see the beginning of time and the universe. This caused a number of negative effects upon the universe at large, which according to legend included the creation of evil, entropy (causing the universe to be born 1 billion years old), formed the Anti-Matter Universe, and a variety of other things which may or may not have happened as a result of the experiment. It is certain however, that this experiment did take place, and that horrific consequences occurred as a result of it. Feeling guilty, a number of Maltusians relocated from Maltus to the centre of the universe to the planet Oa, and named themselves the Guardians of the Universe, in order to stem the flow of chaos and discord alledgedly caused by the experiment. They disassembled Krona, atom by atom, and scattered him across the cosmos, and began a series of attempts to build an effective peace keeping method, which included the building of the manhunters, and finally the creation of the Green Lantern Corps. circa 3 billion years prior to the present.

Oa Then and NowEdit

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. Oa's star is called Sto-Oa (the Light of Oa) by the children of the planet's inhabitants. 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 Superman-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 Sinestro Corps. Afterward, the Corps doubled its defenses. The planet-wide defence-systems were later destroyed by Scar utilising the Book of the Black, though she mentally updated the Oan central intelligence systems with information that unknown seismic activity caused the shell to rip itself apart

The Blackest NightEdit

Oa itself has come under attack once again. As Scar kidnaps the Guardians and takes the to Ryut, the Black Rings descend upon Oa, and ressurrect the Crypts and all of the dead prisoners from the failed Sciencell riot. The Black Lanterns are continuously reinforced by multiple reanimated beings, including the Black Lantern Corphans, and nearly succeed in destroying the Central Power Battery. However, the planet Green Lantern, Mogo, jumps from trnas-luminal travel, and uses his gravity field to suck all of the Black Lanterns into his core, removing them as a threat forever. The remaining Lanterns are summoned by Indigo-1 as Nekron, mastermind of the Blackest Night has appeared and begun his assault on the living universe on earth. All the other Lanterns of the Universe travel immediately to the newly relocated Black Lantern Central Battery to help stop Nekron once and for all, appearing over the Earth and engaging the reformed Black Lantern planet Xanshi and its horde of Black Lanterns.
