The past and present of the DC Universe are colliding in the upcoming story We Are Yesterday, in which Justice League Unlimited and Batman/Superman: World's Finest will crossover as heroes of multiple eras take on Grodd, the psychic gorilla warlord, and his new/old incarnation of the Legion of Doom.
Mark Waid is writing both titles, and along with artists Travis Moore, Clayton Henry, Dan McDaid, and Dan Mora, he's crafting a four part event that brings the underrated Grodd to the forefront, pulling together threads that have been dangling throughout his Justice League Unlimited run as well as World's Finest.
