VANDAL SAVAGE PUTS IVY IN THE CROSSHAIRS! Somewhere in the headquarters of the Gotham City Police Department, Vandal Savage hides a chemical weapon designed to kill Poison Ivy...but if Ivy dies, there will be no ending the bad night of Bad Seeds, for Gotham City or anywhere else. No power. No comms. A heavily-armed private militia tasked with bringing him down on orders of the worst person in Gotham. All holed up together within an impenetrable fortress. This sounds like a job for Batman.
