The current-day adventures of Justice League Unlimited meet the past heroics of Batman/Superman: World’s Finest in the first crossover of the DC All In era, We Are Yesterday!

The sinister psychic powers of the devious Gorilla Grodd have the Man of Steel and the Dark Knight in their sights, but all is not as it seems to be! There’s something strange going on here…some monkey business that the World’s Finest can’t quite put a finger on. It’s almost as if this Gorilla Grodd has…knowledge of the future?

A brand new, six-part event storyline brings the Justice League Unlimited face-to-face with some of their most infamous enemies in a time-bending showdown! Legendary writer Mark Waid and superstar artists like Clayton Henry and Travis Moore have teamed-up to tell an event story like none other, bringing super villains like Gorilla Grodd, the Cheetah, Lex Luthor, and the Joker into the spotlight in a brand new way, and up against a brand new incarnation of the Justice League!

Collects Batman/Superman: World’s Finest #38-39, Justice League Unlimited #6-8, and Batman/Superman: World’s Finest 2025 Annual #1.
