Harley Quinn #5

Harley Quinn trades her mallet for a giant syringe and a blood-spattered nurse's outfit on Amanda Conner's delightfully unhinged cover to issue #5, where she poses triumphantly beside an armored, Hawaiian-shirt-wearing elderly man riding a flame-decaled mobility scooter — perfectly teasing the story inside, "The Hunt for Red Octogenarians." Written by Conner and Jimmy Palmiotti with interior art by Chad Hardin, this 2014 New 52 entry leans hard into Harley's anarchic charm, mixing dark comedy with just enough menace to remind you she's still very much in charge of whatever chaotic situation she's wandered into.
