- "I was sent here to protect my cousin. Turns out, he didn't need my protection. But there's a whole planet full of people who do. Earth doesn't have just one hero anymore. Now it has me. Now it has... Supergirl."
- —Kara Zor-El[src]
Earth was the third planet orbiting the solar system's yellow sun. It served primarily as the home planet of humans, but eventually became home to countless aliens, including a number of heroes such as Superman, Supergirl, Martian Manhunter, and Dreamer.
The planet was sometimes referred to as Earth-38 in reference to its location in the multiverse. This name was often also used to refer to the universe this planet was located in.
In 2019, the entire planet was vaporised by a wave of antimatter, presumably killing all of the residents that were not relocated via transmatter portal to Earth (Earth-1).[1]
History[]
In prehistoric times, Earth-38 was populated by dinosaurs, before they were wiped out by Rama Khan and the Jarhanpurians.
At some point, Kal-El and Kara Zor-El were both sent to Earth due to Krypton's impending destruction.[2]
It was home to vigilantes like Superman, Supergirl, Martian Manhunter and Guardian. Aliens were given all human rights as citizens with the Alien Amnesty Act by the former U.S. President Olivia Marsdin, who is also an alien.[3]
The Earth was also the target of several alien invasions, such as the Kryptonian army invasion using the Myriad,[4] the Daxamite invasion,[5] and the invasion and terraformation of the Worldkillers, but all of them were defeated by the heroes of the Earth, including Superman, Supergirl, and many others.[6]

During the sabotage of Venture, as the spacecraft fell to Earth, both Supergirl and Superman saw the report on the news, coming to the aid of the ship in their first joint effort. Superman put out the flaming oscillator, before the two of them moved it at such an angle that the Venture was able to land relatively smoothly.[7]
Supergirl managed to revert the Claymore satellite's attack into a different location so that it would not directly attack the White House in Washington, D.C. (Earth-38), and saw it destroyed.[8]
Anti-Monitor Crisis[]
Following the rest of the Solar System, the planet was later destroyed when the antimatter wave destroyed all of Earth-38 during the Anti-Monitor Crisis. However, three billion people evacuated through the transmatter portal to Earth-1, before the quantum tower fell.[1]

Erased future[]
In a future timeline, a mass extinction caused by the Blight led to the loss of much of Earth's history and population;[9] Mon-El came to live on this future time after going through a time wormhole to form the Legion.[9] By then, 25th-century L-Corp develops a cure for lead poisoning, allowing him to survive in the atmosphere of Earth;[9] he returned to the 21st century to defeat Blight's predecessor. The timeline was likely subsequently erased afterwards.[10]
