books. In other media Television A variation of Earth-2 appears in the Lois & Clark: The New Adventures of Superman live-action series episode "Tempus Anyone?" Time-traveling author H.G. Wells takes Earth-1 Lois Lane to a parallel universe version of Metropolis that has Clark Kent, but no Superman. While inspiring this alternate Kent to become the Superman of his world, Lane discovers her counterpart had died years earlier and also encounters James Olsen, owner of the Daily Planet; mayoral candidate Perry White; and Kent's fiancé Lana Lang, who kept him from using his powers. While Earth-2 Kent became Superman, he sacrificed his civilian identity in the process. In the episode "Lois and Clarks", Earth-2 Kent came to Earth-1 following an encounter with the time-traveling sociopath Tempus, who trapped Earth-1 Superman in a time loop. A variation of Earth-2 appears in the Smallville series live-action series. Resembling the Post-Crisis Earth-3, this version of Earth-1 is a dark mirror-universe where Clark Kent was found and raised by Lionel Luthor instead of Jonathan and Martha Kent and helped him take control of the world by turning him into Ultraman. The only known way to access this universe was through the Kryptonian Mirror box, but Lionel escaped to Earth-1 to assume his dead counterpart's position in Luthorcorp while Clark destroyed the box. A variation of Earth-2 appears in live-action media set in the Arrowverse: Earth-2 first appears in season two of The Flash. While possessing some similarities to Earth-1, the architecture, fashion, and entertainment outlets resembled mixtures of contemporary 21st century and 1940s styles. Furthermore, certain areas of science and technology were far more advanced than on Earth-1 and the inhabitants of Earth-2 appear as opposites in regards to personality and circumstances compared to their Earth-1 doppelgängers. Earth-1 and Earth-2 were originally connected by a wormhole after Eobard Thawne was erased in season one finale. After the singularity collapsed, the explosion opened 52 breaches throughout Central City that allowed passage between the two worlds, though only by speedsters or through technological means. This universe was the home of Harry and Jessie Wells, the evil speedster Zoom, and Black Siren (Laurel Lance's doppleganger). Earth-2 also appears in the Arrow episode "Starling City". Oliver Queen visits Earth-2 to retrieve Dwarf Star particles for the Monitor. He succeeds before Earth-2 is destroyed by an anti-matter wave sent by the Anti-Monitor, though Black Siren managed to escape with him.
