PRIMER ON MULTIPLE EARTHS
The DC TV Universe has too many heroes for one dimension to hold…
Home of Barry Allen’s Flash, Oliver Queen’s Green Arrow, and the late Laurel Lance’s Black Canary; as well as Ray Palmer’s Atom and his fellow Legends of Tomorrow.
Earth-Two’s Barry Allen has no powers. Here, Earth-One Barry’s friends Caitlin Snow and Cisco Ramone have (now deceased) evil metahuman doppelgängers. Also holds Gorilla City.
The home of Kara Danvers’ Supergirl and Clark Kent’s Superman.
The home of Jay Garrick’s Flash, whose speed was stolen by Earth-Two’s Zoom.
