Poison Ivy (The Batman)

Poison Ivy is a villain in the The Batman series.

Pamela Isley is charming, clever and quick-tempered schemer, known to go to extreme measures in order to get her environmental message heard. After a tragic accident which transformed her into a Human/Plant hybrid known as Poison Ivy, she is able to control anyone who gets a whiff of her plant pheromone spores.

Pamela is still a High School student and obsessed with plants (she is also seemed to be best friends with Barbara Gordon). Anything or anyone that harms Mother Nature is an enemy to Ivy.

In order to carry out her plans against the industries that are harming plants in Gotham City, Pamela hires Temblor to do her dirty work. After Temblor's payment for his jobs doesn't come through and he learns his "boss" is really a teenage girl with a voice scrambler, he attempts to get rid of her. During the fight, Batman shows up to detain Temblor, but before he can completely save her, she is exposed to a powerful dosage of plant growth accelerator which begins her transformation as Poison Ivy.

Ivy then captures Commissioner James Gordon and attempts to kill him; before she can, Batman shows up to stop her. She quickly puts him under her command with her mind-controlling dust. Batgirl shows up and manages to save her father but is overpowered by Ivy and Batman; despite this, Batgirl was able snap Batman out of the control and then the duo take down Ivy.

A period of time later, the Mayor planned to tear down Gotham Park and its Plants in order to build a new Childrens Hospital. His choice was despised by many people within the city including Poison Ivy herself. So, she hit the city's most powerful people and infected them with a flower that put them in plant pods stasis them and infecting them with a virus that made them think they were enjoying nature. She also managed to capture the Penguin. Meanwhile, plant clones took their place in the real world. Batman, however accidentally killed the clone of Penguin, only to find out that it wasn't Penguin, but his plant double. After saving Batgirl, they found Poison Ivy, and her plans were foiled.

She was one of the many prisoners of Rumor. After being released, she was defeated by Batman and Robin alongside the other criminals.

Also, she was later captured by Superman's arch-enemy, Lex Luthor, who was able to obtain from her mind-controlled spores that were laced with Kryptonite dust which allowed him to control Superman.
