I’ve always thought that the Batman villain Poison Ivy is more sympathetic than not, devoting her life to taking care of plants and the environment, even if she doesn’t care much about the human cost. In a brand-new variant cover for her solo series, she’s showing how seriously she takes her goals, cradling a whole human skull (with spine still attached) in her palm.
