She is often portrayed in the comics as a supervillain, but hardcore environmentalists might disagree with that judgment call. Poison Ivy is obsessed with plants, botany and environmentalism — so much that her passion often leads to acts of eco-terrorism.

She can also use plant pheromones to make her sexual advances irresistible, though her green, form-fitting one-piece bathing suit helps, too.
