Warning! Spoilers for Batman #114 by DC Comics below
DC Comics just confirmed that Poison Ivy could become one of the greatest heroes ever but chooses not to. In Batman #114, Miracle Molley and Queen Ivy have a conversation about the state of Gotham City, where the former tells Ivy if she let go of her anger and baggage, she could become one of the world's best heroes. However, Poison Ivy has no interest in doing so.
Poison Ivy is at an interesting place in current DC Comics stories. The longtime villain has become Queen Ivy after being experimented on by the Magistrate and splitting into two bodies and personalities. Harley Quinn has made it her quest to reconnect both versions of Poison Ivy and get her girlfriend back in one piece. In the meantime, Queen Ivy has taken over Gotham's underground, creating Eden, which is her own city of the green. With Gotham City falling to pieces above her, Queen Ivy had no intention of helping those above her. But, thanks to Quinn's convincing, she's taken in the Unsanity Collective under her protection.
In Batman #114 by James Tynion IV, Jorge Jimenez, Tomeu Morey, and Clayton Cowles, the comic opens with Miracle Molly and the Unsanity Collective in Queen Ivy's home in Eden. Queen Ivy notices Molly tinkering with a radio, which is transmitting propaganda from the Anti-Oracle. After asking her if she's angry, Molly responds that she's angry about the trauma and disinformation being spread in Gotham. Molly tells Poison Ivy if she let go of her baggage and anger, she could become one of the world's greatest heroes, while also suggesting she has the power to topple Gotham and chooses not to.
Of course, Queen Ivy doesn't want to lose her baggage and anger, as she reveals it gave her the necessary tools to survive in Gotham City. She tells Molly she's too optimistic and to cater to people who have succumbed to fear countless times is not something she wants to do - not after how they shaped the world to how it is.
Molly Miracle is right that Poison Ivy could be one of the greatest heroes Gotham City has ever seen if she focused her abilities on good. However, Queen Ivy's become disheveled in what the world has become and has no interest in dropping her baggage and anger to make that happen. Poison Ivy could be a hero on the level of Superman, Batman, and Wonder Woman, but her experience in see what has become of the world has led her to believe some people aren't worth saving. Batman #114 is in comic book stores now.
