Batman: Arkham Asylum Episode 9: Poison Ivy Boss Battle - The island is dying. Ivy’s corrupted plants are surging out of the ground like veins of venom, twisting steel and stone into a living nightmare. Her connection to Titan has grown beyond comprehension, turning her into something more monster than human. If Batman doesn’t stop her now, Arkham will be swallowed whole — and Gotham soon after. With the antidote secured and the contamination halted, Batman races back to the Botanical Gardens. The once-beautiful greenhouse is now an overgrown fortress, pulsing with unnatural life. Every corridor is infested with mutated spores and thorned vines that lash out violently at anything that dares to enter. The gardens have become Ivy’s kingdom — and she knows he’s coming. Ivy’s mind-controlled "flower children" — reanimated guards wrapped in plant matter — attack with unnatural strength and abandon. The closer Batman gets, the more violent nature becomes. Finally, at the heart of the gardens, Ivy emerges — fused into a grotesque floral monstrosity. Towering above, seated within a monstrous, blooming pod, she lashes out with massive vines and spits barrages of toxic spores. The ground trembles with each of her attacks. Batman must dodge and strike at the right moment, waiting for Ivy to expose herself before launching Batarangs into the core of her monstrous bloom. The battle escalates. Ivy’s vines thrash harder, her attacks more frenzied. Batman uses every tool at his disposal — dodging, gliding, striking — until finally, with one last well-timed explosive, Ivy's mutated form collapses, and the titan-fueled infection recedes.
