This is the YMMV page for Poison Ivy, a DC Comics character and nemesis to Batman.
- Alternative Character Interpretation: LOADS of it. Even writers can't quite determine what type of person she is, underneath, whether she's really a decent soul twisted by past abuses and Lovecraftian Superpowers, or if she's a megalomaniacal terrorist and unrepentant murderer. Even her thoughts on Batman are inconsistent between writers, whether she's attracted to him despite being willing to kill him or is genuinely in love with him.
- Audience-Alienating Era: Her Post-Heroes in Crisis characterization, which amounts to Ivy being Stuffed in the Fridge to give Harley Quinn motivation, only to be brought back from the dead within the same series as more plant than human. Not only has she been effectively turned into a blatant rip-off of Swamp Thing to the point she looks like she's been skinned alive and has no nipples or genitalia, but her killer (and the person who brought her back) was Wally West, of all people. The follow-up series Harley Quinn & Poison Ivy only made this more of an Audience-Alienating Era when it was supposed to fix the damage done to Ivy. After six issues of Harley trying to help Ivy deal with her trauma (as in, trauma she received at a place that was supposed to help her pre-existing trauma), it turns out there are now two Ivys (one calm and gentle, the other angry and vengeful). The calm Ivy tells Harley to escape as she fights and later merges with angry Ivy, in the process only kissing Harley on the forehead before she departs. So after brutalizing Ivy and dehumanizing her, DC treated her fans to six issues of queerbaiting between her and Harley. It then turned out the two Ivys never actually merged at all, with the angry one becoming Queen Ivy while the calm one was abducted and put in stasis so drugs could be harvested from her biochemistry over in Catwoman.
- Best Known for the Fanservice: Her status as a half-naked plant woman is easily her best-known attribute.
- Cant Unhear It: You're likely to hear either Diane Pershing, Tasia Valenza, or Uma Thurman while reading comics. Time will tell if Lake Bell and her deadpan take on the character shakes things up.
- Complete Monster: Not usually, but in Batman & Robin, Ivy, formerly Dr. Pamela Isley, relishing in her newfound power, she declares herself Mother Nature and wishes to start anew for the world. Delighting in murdering numerous men with her painful poison kiss, Ivy tries to turn Batman and Robin against one another with her pheromones, seemingly murdering the sleeping Nora Fries to provoke Nora's husband to true despair. Deciding to help him kill every living thing in the world after freezing Gotham solid, Ivy intends to enact her own fantasies of creation upon the new world she creates.
- Ensemble Dark Horse: One of Batman's best-known and most endearing archenemies, she has gained a massive fanbase among "nontypical" people, particularly LGBTQ people, both for her fluid sexuality and for her flawed morality, which many feel is closer to their own than the cut and dry moralities of Superman and Batman.
- Foe Yay Shipping: Has tons of it, due to her seduction powers. Her attraction to Batman is canon and he is the most prominent male she's paired with, but she's also had it with: every Robin, Batgirl, Superboy, Superman, and Supergirl.
- Les Yay: Her sexuality has been speculated upon for years, especially due to occasions where she has deliberately attempted to seduce female characters as well as men. That's not to even mention her relationship with Harley Quinn, which was later canonized. Given that she's part plant, it's arguable she's biologically bisexual.
- LGBT Fanbase: After Harley and Ivy's relationship was confirmed, Harley's popularity exploded within the LGBTQ community, as well as the Polyamory community.
