With Bruce Wayne (Batman) away, Kal-El (Superman) dead, Diana Prince (Wonder Woman) having gone back to Themyscira to be with her family, Barry Allen (The Flash) busy in Central City, Victor Stone (Cyborg) not answering any calls, Arthur Curry (Aquaman) fulfilling his job as king of Atlantis, and Hal Jordan (Green Lantern) busy training the new Green Lanterns, the younger members of the Justice League get together and pose as the older members when monsters attack Gotham City, Coast City, Blüdhaven, Metropolis, National City and Opal City.
