MULTIVERSUS COLLISION DETECTION #3

MAYHEM IN THE CITY OF TOMORROW! Metropolis's newest city-wide battle has everything: Green Lantern, Hawkgirl, a child with a gem on his shiny round tum-tum, a sprite-sized Dark Knight, and...the Head. (It's that thing where Brainiac's code gets overwritten by an inebriated scientist who couldn't be bothered to hang around for the entire issue!)
