Overview

  • On July 28, James Gunn released high-resolution images and a character breakdown of the Hall of Justice mural, revealing a 300-year timeline of 26 DCU metahumans.
  • The mural spotlights both iconic and obscure heroes—ranging from Justice Society veterans like Wildcat and Dr. Fate to lesser-known figures such as Sister Symmetry and Super-Chief.
  • Production designer Beth Mickle said the artwork drew on WPA-era murals and Cincinnati Union Terminal architecture to inspire rather than prescribe future storylines.
  • Gunn described the piece as a tribute to DCU’s legacy, intended as an Easter egg-rich world-building device rather than a strict project roadmap.
  • Several characters have already been assigned to upcoming DCU projects, with Maxwell Lord confirmed for Peacemaker and two others linked to an unannounced script.
