Oa (Earth-7642)

**Oa** is a planet that lies in the center of the universe. It is used by the Guardians of the Universe as the home base to the Green Lantern Corps.

## History

### Ancient History

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. When the scientist Krona tried to discover the creation of the Universe a wave of evil engulfed the worlds and created an Anti-matter Universe of evil. He was exiled for this crime and the Oans tried to protect the Universe.

### Oa Then and Now

One of the oldest planets, Oa serves as the home and headquarters of 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 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.
