Batman’s rogue gallery has long been revered for featuring some of the most complex, nuanced villains in the history of pop culture. Characters like Two-Face and The Riddler have displayed mental health conditions that skew their perspectives of the world and another character who belongs in that category is Poison Ivy.
Poison Ivy is traditionally portrayed as a seductress who uses her powers to make others do her bidding. But to only see this side of her does a disservice to the character. Ivy is motivated to protect nature against humanity, a crusade that’s exacerbated by her suffering from Seasonal Affective Disorder (SAD).
