Earth-12 is one of the realities in the Multiverse, home of Harrison Wolfgang Wells. This universe is patrolled by the Green Lantern Corps, a space police force which is based on planet Oa, under the control of the Guardians of the Universe.


Pre Crisis

In ancient times, the Guardians of the Universe created the Green Lantern Corps to protect the peace in every corner of the universe. The Guardians also stored the Book of Oa which contains the secrets of the Multiverse.

At some point in 21th century, Harrison Wolfgang Wells became an important figure in science.

In 2019, when the Anti-Monitor's Crisis erupted, Phantom Stranger led Felicity Smoak, escorted by the Ray and Nyssa al Ghul, to this universe, on planet Oa, to retrieve the Book of Oa in order to discover the identities of the Paragons.[1]

The Guardians expressed their opposition to the use of the Book but they were interrupted by Shadow Demons of the Anti-Monitor. Led by Sinestro, the Green Lantern Corps battled the multiversal fiends and overpowered them; at the same time, a Guardian, Ganthet, guided Felicity to the Book, that showed her every event ever happened so she discovered the identities of some of the Paragons.[1]

Later, this reality was destroyed when an anti-matter wave was unleashed upon it by the Anti-Monitor[2]. After the Paragons rebooted the multiverse, Earth-12 was restored along other Earths of the multiverse.[3]


After the restoration of Earth-12, it was still protected by the Green Lantern Corps, with the addition of the Earthling Hal Jordan. The new recruit helped the Corps defeat the embodiment of Fear, Parallax.[3][4]





  • After the Crisis, it is also shown to be home to something similar to the movie Green Lantern.
    • The cameo scene could also be inteded to be a pun of the incoming HBO Max series Green Lantern Corps.
