"Poison Ivy" was a poisonous variant of the Ivy B.O.W. accidentally created following exposure to the P-ε gas in the Underground Laboratory in Raccoon City.
Attributes
The Poison Ivy begins existence as a normal Ivy. Unlike most other B.O.W.s, Ivy can adapt to P-ε gas and presumably other airborne poisons. Following exposure, the Ivy develops a reddish or purple hue in its flower and upper body, and it becomes capable of secreting poison in digestive fluids. Though it is tempting to speculate that the poison is related to P-ε, no evidence exists to confirm or deny this hypothesis.
The Poison Ivy is similar to normal Ivy in all other characteristics.
