The relationship between Quinn and Isley did not happen spontaneously nor upon a "love-at-first-sight" moment of epiphany. They first met on January 18, 1993, during the Batman: The Animated Series episode titled "Harley and Ivy," and their inevitable meeting was the beginning of their history to follow.
Poison Ivy is 21 years old. Her birthday is on December 4, 2001.
In a desperate hope to break free, Harley kissed Ivy, believing true love would free her from Dr. Psycho's control.
Given what we know about the character, despite story nomenclature, the killer kiss is more accurately described as poisonous, not venomous. Regardless, the result is the same. Contact with Ivy's lips delivers a toxin capable of killing the recipient.
Harley and Ivy make their love HBO official
Ivy realizes her feelings for Harley in the second season finale, after being ditched by her fiance Kite-Man after he deduces she loves someone else.
Harley then joined Ivy atop the truck and began to badger Ivy for an answer about why Harley was Ivy's biggest fear. Fine! You want to know what my biggest fear is? Finally allowing myself to count on someone and then having them ditch me.
They have affectionate nicknames for each other, with Ivy calling her "peanut," and Harley giving her gal a peck under the mistletoe or as she calls it "the kisstletoe." This signifies they're more than just besties, especially as Ivy is adamant about the "no exes" rule.
Harley and Ivy are never stated to be poly in so many words in the comics themselves, but it seems that they are. They flirt a ton and have often implied relationships with other people. Regardless, it's never a fight between them.
Harley and Joker break up because Harley is sick of living in Joker's shadow. She was more intelligent than the Joker and often planned their major heists. However, Joker always took all the credit.
The couple got together on Harley Quinn's first season, with Season 2 following the engagement of Poison Ivy and Kite Man. Unfortunately for Kite Man, Harley (voiced by Kaley Cuoco) burned their marriage to the ground after finding out she was in love with Ivy.
Poison Ivy's ex-girlfriend Bella Garten, also known as the Gardener, makes an unexpected reappearance at the end of DC's Harley Quinn: The Animated Series - Legion of Bats #1.
Ivy leans in for a kiss with a love-struck Robin. She quickly cornered him on the railwalk before he could help Batman and blew Love Dust in his face again.
Ivy successfully delivered her two sporelings in secret, naming them Rose and Hazel.
Ivy repeatedly calls Harley stupid, recklessly hurts her feelings, hits her several times and at one point is bashing her head against a tiled floor. It's all presented as comic relief, but if you stop to seriously consider this behaviour, it's incredibly abusive and violent - on a physical and emotional level.
Background. Poison Ivy, aka Pamela Iseley, came from an abusive home. Her father beat her mother every night until one night he killed her, hiding the body in the garden. He was later arrested for her murder.
But with both Gotham villains currently headed down different paths of self-discovery in the comics, they quietly called it quits. “Our story…it's not over,” Harley tells a teary Ivy in Harley Quinn #10. “But you need to find your own path, too.
Poison Ivy is depicted as being a seductive temptress who is fully aware of her beauty and will use it to get what she wants, aided by the pheromones her unique biology provides for her.
Batman: Hush
Soon after her deal with Hush Ivy found Catwoman to steal the money for her and forcefully kisses her to keep her under control.
Mental instability: Due to Poison Ivy's obsession with plants, when she thinks that they are being threatened, she becomes unstable, destructive, and filled with rage. She is willing to save her plants at all costs, even if she has to surrender to Batman or ask for his help.
Weakness: A lack of sunlight will progressively weaken Poison Ivy's powers as she is a human-plant hybrid. Perhaps even more important, however, is her mental instability. When Poison Ivy became a supervillain, she was driven insane and is often portrayed as a mad genius.
Poison Ivy hates all humans because they have hurt her and they have contaminated the world. During her time in Arkham Asylum, she can't stand her psychiatrist, Harley Quinn, then known as Harleen Quinzel.
