Earth-1[1] is one of the many universes in the vast Multiverse.
History[]
Arrival of Enchantress and Incubus[]
In 4358 B.C., the inter-dimensional beings Enchantress and Incubus traveled from their dimension to Earth-1, where they appeared before the people of South America on Earth. They were worshipped by and ruled over a group of ancient humans but were eventually overthrown and imprisoned inside the Tres Osos Caves.[2]
Invasion of Earth[]

Uxas arrives on Earth
When the New God warlord and conqueror Darkseid of Apokolips discovered the Anti-Life Equation on Earth, he orchestrated a large-scale invasion of the planet from "the dark place" so that he could take the power of the Equation for himself. However, he and his army were driven back by the forces of Men, Atlanteans, Amazons, and Old Gods, who had formed an alliance and were being assisted by the Green Lantern Yalan Gur.[3]
Meeting of the Flashes[]

Barry meets an alternate version of himself
At some point, Barry Allen wound up in a memory of S.T.A.R. Labs from another Earth by accessing the Speed Force, accidentally coming across an alternate version of himself in the process. He asks the other Flash if his suit is cosplay and if he wants a selfie, to which the other Flash says no, exclaiming that he is also the Flash. Before the other Barry could explain the situation any further, Barry faded out while saying that he had told Victor Stone this was possible.[4]
Attack of the Retrobots[]

Serena Williams meets Wonderous Serena
At some point, several Retrobots appear from a portal during an game of tennis and attack the audience. Serena Williams defends the stadium by helping the civilians who were being attacked and meets with an alternate version of herself, crossing a portal to another universe.[5]
Flashpoint[]
In 2022, Barry Allen used his powers to travel back in time using the Chronobowl and save his mother from death. He was successful, but ended up creating an alternate timeline where General Dru-Zod's invasion was successful, Bruce Wayne had retired, and Kal-El had been killed when he was an infant, among other changes.

A new timeline is created.
Frantic to set things right, Barry, along with his counterpart from that timeline, engaged with Bruce and Kara Zor-El to save Earth from Zod. When the multiverse began to collapse due to his meddling in time, Barry was forced to go back in time once again and avoid changing anything. However, he again rewrote the history of his timeline, creating a timeline similar in some ways to Earth-1, but completely different in others.[6]
