History

Origin

During the Crisis of the Infinite Earths, a faction of the Guardians brought Guy Gardner to Oa to make him their Green Lantern and empowered his Power Battery with their own energy when the Central Power Batter was not operational. (Green Lantern v2 #195)

During the Infinite Crisis, Superboy-Prime intended to smash through the planet Oa at the speed of light in order to initiate a new Big Bang to kill everyone whilst leaving himself the only survivor. The Corps confronted him in space where 32 of their number were slain by the mad Kryptonian. Superman and his Earth-1 counterpart managed to enter into the fight where they plunged Superboy-Prime through Krypton's red sun and to the surface of Mogo where the star had rid him of his protective armour. The three battled on the surface where Superboy-Prime fatally wounded the Earth-1 Superman thus killing him but had become exhausted in his fight leading to him collapsing. The Green Lantern Corps then encased him in a cell near a junior red Sun-Eater to deprive him of his powers whilst a detail of 50 Green Lanterns kept watch over him. (Infinite Crisis v1 #7)

War of Light

In the aftermath, the Corps proceeded with rebuilding the planet and repairing the damage made by the Black Lanterns. (Green Lantern Corps v2 #48)

It was later attacked by Relic who had come as part of his quest to preserve the Emotional Spectrum by dismantling its use by the Lantern Corps. He dispatched his machines to drain the Central Power Battery of its energy and then destroyed it with the Green Lanterns unable to stop him. (Green Lantern v5 #24) This caused a chain reaction which ultimately destroyed the world though the Corps was able to activate their Escape Protocol that launched the Citadel into space as an escape craft whilst all the prisoners in the Sciencells were allowed to escape and many Green Lanterns managed to evacuate in time before the planetary cataclysm. (Green Lantern Corps v3 #24)

New Oa

The Guardian's then decided to rebuild the planet which they did so in secret and was overseen by Kada Sal until his death due to the secret machinations of Hank Henshaw. With the Cyborg Superman defeated, the Guardians decided to relocate to the rebuilt Oa in order to allow Mogo the chance to recover from the crisis. (Green Lanterns v1 #57) Thus, the Guardians created New Oa that became the Central Precinct of the Green Lantern Corps once more. (The Green Lantern v1 #1)

Overview

Located in the centre of the universe, it was noted for being a strange and unique planet. (DC Comics Presents v1 #60) Oa was a far-distant planet situated in the central galaxy of the universe. (Green Lantern v2 #1) It orbited the star called Sto-Oa which translated to mean "The Light of Oa". (Sandman: Endless Night v1 #1)

Metalline Oamite under constant pressure was nearly unbreakable. (Green Lantern: Emerald Dawn v1 #5)

The Central Power Battery in Green Lantern v2 #200.

The planet consisted of numerous locations which included:

  • Warriors : a bar and restaurant made by Guy Gardner. (Green Lantern Corps v2 #27)
  • Evidence Vault :
  • Foundry :
  • Hall of Great Service :
  • Hazard Simulation Facility :
  • Planetary Citadel :
  • Battery Park : a location situated on the planet. (JLA v1 #86)
  • Sciencells : these were prison cells that were sealed shut by green power and used to hold captives with them being deemed impossible to escape as long as energy was maintained to them. (Green Lantern v2 #195)
  • Subcells : these were solitary cells where the most dangerous prisoners of the Corps were kept sequestered from the general population in the Sciencells. (Green Lantern Corps v3 #11)
  • Crypts of the Green Lantern Corps : situated deep beneath the citadel that followed the old Maltusian burial customs of a single large crypt for all their heroes situated deep beneath the ground but close to the souls of the living so that they could commune with the dead. (Guy Gardner: Reborn v1 #3) Those whose remains were recovered where entombed in the glass coffins whereas others had graves that were empty due to their mortal forms being destroyed or lost. (Green Lantern v4 #12)

Most of the structures of Oa's surface were barely a million years old and thus recent construction. Ancient Oan architecture was said to be capable of withstanding far greater levels of damage and punishment. (Green Lantern Corps v2 #48) Beneath the central Citadel, there was a number of research tunnels situated underground that led out from that location. Within the tunnels were guide posts that indicated the destination to either the citadel or further deeper into the sand deserts on the planet with transportation cars available. (Green Lantern v2 #195)

Chief among the features on the planet was the Central Power Battery that were tapped into by Power Rings which served as a conduit to its main power. To help manage its functions, it was equipped with a form of artificial intelligence. (Green Lantern: Rebirth v1 #3) The Central Power Battery provided crucial life support to the planet. (The Flash v1 #221) After its installation on Oa, its infrastructure became embedded throughout the underground catacombs and reached to the core of the planet. (Green Lantern v5 #24) This great battery of power was attuned to the smaller Power Batteries used by the Green Lantern Corps to charge their Power Rings. It was capable of speech and able to inform others about dangers to its existence. Thus, the Prime Battery were able to notify others of any attempts to siphon its power. (DC Comics Presents v1 #60)

For a time, the world was protected by the battery shell that was a large power battery shaped construct that served as a armored defensive layer until its destruction. (Green Lantern Corps v1 #37)
