Poison Ivy has poisonous lips, one kiss being instantly fatal, able to produce pheromones to seduce any man, gains nutrition via photosynthesis like a plant meaning being deprived of light weakens her and a psychic connection to plants called the "green".
Poison Ivy spends her time creating monsterous plant organisms, these freakish vegetables are more animal then plant. Some have vines for strangling or constricting others produce poisonous and paralysing pollen.
Some of her most infamous experiments were, the vagina mouth plants, the plant hulks that melt in contact with water, (I'm meltiiing! I'm melting! Oh what a cruel world! Who would have thought a small drop of water would ruin my beautiful wickedness?) and many others.
Clayface, all of them.
