Arrowverse Earth-X

On this universe's Earth, the Axis Powers won World War II after Nazi Germany successfully developed their atomic bombs before the United States did[203]

Adolf Hitler died of natural causes in 1994.

This Earth's timeline was akin to Earth-1, Earth-2, and Earth-38's to a certain degree, such as its Oliver Queen becoming a trained archer, Kara Zor-El's arrival after the planet Krypton's apocalyptic demise, and Quentin Lance fathering Laurel and Sara Lance.

The Freedom Fighters consist of the Ray of Earth-1, Uncle Sam, the Black Condor, the Human Bomb, the Phantom Lady, a version of the Red Tornado,[204]General Winn Schott, and Citizen Cold (an alternate, heroic version of Captain Cold).

Members of the New Reischmen include Overgirl (an alternate version of Supergirl), the Dark Arrow (an alternate version of the Green Arrow),[204][205] the Black Arrow (a look-alike of the Green Arrow), Blitzkrieg (a variation of the Flash), a version of Tommy Merlyn who operated as Prometheus, an alternate version of Metallo, and Siren-X (an alternate version of Earth-1's Black Canary and Earth-2's Black Siren). Earth-1's Reverse-Flash was also involved with them.

Quentin Lance was a Sturmbannführer of the New Reich.

This universe and its inhabitants were destroyed by an anti-matter wave in "Crisis on Infinite Earths: Part One".[167]
