DC reveals Poison Ivy’s kryptonite, which powers her upgraded powers

WARNING: CONTAINS POTENTIAL SPOILERS FOR GOTHAM CITY SIRENS #3!

Sam Ivy Has gone through many transformations over the years, evolving from one of Gotham’s most formidable metahumans to attaining literal god status, only to lose her plant-controlling powers completely and then regain them once again. It’s been a wild ride for the Gotham City siren, and now that her overpowered ability to control plants has returned, she faces a newly revealed weakness.

Leah Williams, Matteo Lolli and Triona Farrel’s Gotham City Sirens #3 continues the Wild West adventure of Catwoman, Harley Quinn and Poison Ivy as they attempt to take down Punchline and her violent, highly illegal, energy drink-sponsored hunting operation that threatens the wildlife and residents of Gotham City.

Despite the trio’s efforts, Punchline gets the best of them, imprisoning them in one of her prison cells. She cranks up the heat, hoping to dehydrate the Sirens enough to force them to drink her mind-controlled energy drink. It is during this heated prison cell scene that DC reveals Poison Ivy’s kryptonite – excessive heat.

DC Reveals Poison Ivy’s Kryptonite Is Excessive Heat (And It Makes Perfect Sense)

Ivy’s vulnerability to excessive heat goes hand-in-hand with the return of her plant control powers

While all three sirens suffer from the excessive heat, it is clear that Ivy is the most affected and at risk of dying. As Selina and Harley search for a way out of the cell, Evey lies curled up on her side on the floor, slowly wilting away, prompting Harley to do, “We are running out of time. Ivy will not survive much longer. Harley’s comments, along with Ivy’s lack of movement and verbal response, emphasize that the plant-loving Siren is in critical condition and just as susceptible to excessive heat as her beloved plants.

With Ivy recently regaining her plant control powers in G. Willow Wilson’S. Sam Ivy Flow, the discovery of this new weakness is particularly well timed and makes sense. As any current or former plant owner knows, one of the quickest ways to kill a plant is by subjecting it to excessive heat. therefore, Ivy’s renewed plant powers come with a plant-specific weakness that feels particularly fitting. It’s also neat to see this vulnerability revealed in a series written by a different writer than Ivy’s main run. This highlights DC’s overarching brilliance, making their separate stories feel more interconnected.

Poison Ivy’s vulnerability to excessive heat goes perfectly with her other plant-inspired weakness

Evey’s final weakness also proves why Arkham is the worst place for her mental and physical health

Poison Ivy has relatively few weaknesses, but in addition to her sensitivity to heat, previous canon establishes that she relies heavily on sunlight – making sunlight deprivation another potential vulnerability. This weakness suits Ivy, as it aligns with her plant-based powers, much like her sensitivity to excessive heat. It’s also worth noting that Evie’s need for sunlight makes Arkham Asylum one of the worst places for her, as the lack of natural light would negatively impact her physical and mental health. together, Poison Ivy’s Vulnerability to sunlight deprivation and her sensitivity to heat add depth to her character and powers.
