The HBO Max animated series Harley Quinn features an incredibly powerful Poison Ivy, taking elements from several different versions in the comics. Ivy easily counts among the most powerful supervillains in the DC Universe (depending on how she’s perceived), but some Ivy versions possess more power than others.

Ivy generally uses her power to control plants against Batman in relatively low-stakes schemes in the comics, but modern versions connect to The Green, a powerful natural energy source that transforms her into an almost elemental figure. Other versions rely on her cunning and insight, qualities the comics didn’t always value, but have proved invaluable in her relationship to Harley.

9 DC Bombshells

Most Ivy versions in the comics possess superhuman powers, but that’s not the case with the DC Bombshells version. Though she enjoys a natural immunity against most poisons and toxins, she doesn’t have any powers most versions in other media do. Her green skin comes from exposure to a perfume she concocted to drug Nazi soldiers.

This Ivy does maintain other versions’ unparalleled skill in botany. She often uses her skill in tending plants and knowledge of herbs and poisons in the war effort in this alternate reality.

Ivy also seems to lack her typical superhuman powers in the ‘Lil Gotham universe where all DC characters appear as child-like versions. She nevertheless possesses the same criminal ambition and capacity, always scheming to pull off a major score or operation, usually with Harley Quinn in tow.

Ivy’s logistical and practical sense often goes underappreciated in the comics, but underlines virtually all of her and Harley’s successes, especially in the current animated series. Ivy’s cool and clear-headedness often keeps Harley on track.

7 The Original

The original Ivy from pre-Crisis On Infinite Earths continuity gains the power to control men and women with her own pheromones from involuntary genetic experiments. She also contains a toxic poison that can kill on contact that she usually administers through a kiss, though she can deploy it through any physical touch.

Ivy also possesses immunity to any and all toxins thanks to being poisoned with ancient Egyptian herbs. This original origin story, which has been updated many times since, first appeared in World’s Finest #252. Ivy’s first appearance in comics came in…
