Poison Ivy


Protect the world's natural environment by any means necessary


Usually defeated by Batman

Life endures. It adjusts and grows stronger. The weeds you try to kill become super weeds, immune to your poison. And so you increase your toxins and poison the world in a cycle of madness. I call it forth, the power of the plants, even from the terminator seeds that should not grow. I am the guardian of the Green. I am Poison Ivy.
~ Poison Ivy

Pamela Lillian Isley, known better as Poison Ivy, is an antagonist in the Batman comics. She is a botanical biochemist with an obsession with plant life, and is one of the world's most dangerous and prominent eco-terrorists. She uses toxins from plants and her own bloodstream to aid her in her criminal activities.


Once a college student in botany and toxicology, Pamela Isley was seduced by her professor, Doctor Jason Woodrue, and used as a human test subject in his experiments. The experiments left Isley with a changed physiology, the toxins in her bloodstream making her immune to poisons and and bacteria, and leaving her with a poisonous kiss. She also gained the ability to produce pheromones that she could use to seduce men. 

Moving into Gotham City, Isley took on the moniker of Poison Ivy and became a dangerous criminal and eco-terrorist, dedicated to "purifying" Gotham and protecting the worlds ecosystem. She has had multiple battles with Batman, usually ending with her incarceration.

During her criminal career, Ivy became allies with Harley Quinn, the Joker's sidekick and lover. Harley is one of the few humans that Ivy genuinely loves, and she despises the callous way the Joker treats her. She has made some attempts to save Harley from her abusive relationship.

No Man's Land

Poison Ivy 0010

Poison Ivy during the events of No Man's Land

After the destruction of Gotham in an earthquake, Ivy and the rest of the inmates in Arkham Asylum were released and allowed to run amok. Ivy took up residence in Robinson Park, and took in several orphans, in spite of her hatred for humanity. During the winter, Clayface visited Ivy, planning to bargain with her. Clayface proposed that Ivy and the children work for him in producing fruits and vegetables, and then he would sell them to the highest bidder. When Ivy refused, Clayface imprisoned her and the orphans for several months in a chamber under the lake. Eventually, Batman rescued her, and the two worked together to defeat Clayface.

After Gotham was reincorporated back into the United States, the city tried to evict Ivy from the park and return her to Arkham Asylum. Ivy initially refused, but surrendered herself after Rose, one of the orphans, was poisoned. She later had Batman treat her to reverse her condition and make her a normal human being again. However, this wouldn't last, as Ivy was later convinced by Hush to take a serum that restored her powers.

One Year Later

After the events of the Infinite Crisis, Ivy's flora powers had increased, and had restarted her crusade to protect the environment. She also began feeding unfortunate people to a giant plant which digested them slowly and painfully. However, this proved to be Ivy's undoing, as the souls of her victims merged with the plant to create a giant monster called Harvest, which sought revenge against Ivy. Though she was saved by Batman, Ivy was left in critical condition.

After recovering, Ivy caught the Trickster and the Pied Piper eating one of her fruits. Capturing the two, Ivy would have killed the two if not for the intervention of Deathstroke. Ivy later helped Catwoman in seeking out Hush to exact vengeance upon him.
