in this reality batman failed to stop the music meister and got turned into one of his puppets, with all of the hero's under his control all hope appears to be lost, except for one thing that he overlooked, his power has no effect on death people. since some of them can read lips they have the gist of whats going on, now they have to take back their world from the meister or be destroyed by his puppets for defying their musical master.
