"I think you're remembering that from another time. Another Earth, perhaps."
Lex Luthor[src]

Earth-38[1] was one of the many universes in the multiverse. It was the home universe of Superman and Supergirl. During the Anti-Monitor Crisis, the entire universe was engulfed in a wave of antimatter, with 3 billion of Earth's citizens surviving due to evacuation to Earth-1, making them refugees. Unfortunately, the antimatter wave would later reach Earth-1 as well, killing all surviving inhabitants except Supergirl, J'onn J'onzz, and Lex Luthor.

After Oliver Queen died while battling the Anti-Monitor and reformed the universe, Earth-Prime was formed, which contained most elements of Earth-1, Earth-38, and Earth-TUD5. As such, while this Earth may be physically gone, its people live on as part of Earth-Prime.

History

"You know J'onn J'onzz from Supergirl's Earth?"
"Of course I know J'onn! Wait, go back...Supergirl has her own Earth?"
"Not anymore.
"
Sara Lance, Ray Palmer, and J'onn J'onzz[src]

Alien life was common knowledge for over a decade on the Earth of this universe - in particular, the Kryptonian heroes Superman and Supergirl. Barry Allen accidentally traveled to the Earth of this universe while testing out his tachyon device and was able to return home with Supergirl's aid.[2]

A few months later, Barry and Cisco traveled to the Earth of this universe to recruit Supergirl's help[3] in facing the Dominators.[1]

When Cisco and Gypsy had a duel over the life of H.R. Wells, they crossed the dimensions and landed on this universe's Earth, in the office of James Olsen. They were seen by Eve Teschmacher fighting before vanishing into another breach.[4]

Recently, the atmosphere of Earth-38 had been seeded with a trace amount of lead, making the planet uninhabitable to Daxamites.[5] Though by the 2400's of a now erased future, a cure was invented by L-Corp, allowing said species to stay on Earth without any problems.[6]

Earth-38 being destroyed by antimatter

In 2019, a wave of antimatter sent by the Anti-Monitor destroyed this Earth, however, with the help of Lena Luthor and heroes of Earth-1, the heroes of Earth-38 manage to evacuate 3 billion inhabitants to Earth-1. The Monitor predicted that one third of all survivors were saved by Oliver Queen, sacrificing himself to protect the quantum tower protecting Earth-38 from destruction before the tower, the Earth and Queen himself fell,[7] however, with the help of Paragons and the Spectre, the Earths-38, 1 and TUD5 were merged into Earth-Prime.[8]

After running them by Kara Danvers and looking them up online, it appeared that Harrison Wells, Cisco Ramon, Caitlin Snow, Green Arrow, Black Canary, the Atom, Firestorm, Zoom and even himself, as the Flash, all either did not exist or at the very least didn't share the same names and identities of their counterparts.
