Poison Ivy

Poison Ivy is the third boss faced in Batman: Arkham Asylum.

Description
After Batman's second visit to the Botanical Gardens, Ivy is faced in a large grassy atrium, locked inside a colossal tentacled plant monster gouging out of a large hole in the ground. These tentacles will continously fire streams of explosive spores at Batman that do major damage. Simply roll away, quick fire your batarang (which auto-targets Ivy, causing damage), and roll back. This small pattern will be the majority of the fight, and will only be interrupted by three things: Ivy spawning a horde of brainwashed guards who function like generic enemies, Ivy spawning a patch of tall grass that'll entangle and trap Batman, squeezing the life out of him, which can only be escaped by button mashing, and Ivy getting stunned upon losing enough health, causing her to collapse. This allows Batman to spray some explosive gel on the pod containing her, and the detonation causes major damage. Repeat this entire pattern again and Ivy will be beat.
