This week's "Flash" episode ended with Barry Allen (Grant Gustin) making a bold decision: Team Flash is going to Earth-2! So far the travel from the parallel Earth to the "Flash" reality has flowed one way, with a villains stepping through the rifts to torment the Flash and his friends. All that's changing in "Welcome to Earth-2," which will see the Flash, Cisco and Harrison Wells mount a rescue mission -- and bring them face-to-face with their friends' counterparts.

These pics from the episode feature Killer Frost and Deathstorm, the villainous Earth-2 alternates of Flash allies Caitlin Snow and Ronnie Raymond. The pics also show off the Art Deco stylings of Earth-2 Joe West and Iris West.
