Dr. Sarah Chen was conducting hunger-suppression research when a catastrophic spill exposed her to concentrated appetite-stimulating compounds mixed with mutagenic chemicals. The experimental cocktail didn't just restore her appetite - it transformed it into an insatiable craving for human flesh that consumed her rational mind. Now she prowls the laboratory's ruins, driven by an endless chemical hunger that can only be satisfied by hunting down other survivors.

The Compound Cannibal bears the distinctive yellow-green chemical burns across her skin where the experimental compounds first made contact, creating a mottled pattern that glows faintly in darkness. Her enhanced senses can detect human pheromones from incredible distances, while her teeth have grown sharp and elongated from constant gnawing on bone and cartilage. The chemical transformation has increased her physical strength and speed, but left her in a constant state of ravenous hunger that drives her to increasingly desperate measures. Her lab coat, still partially intact, is stained with both toxic chemicals and the evidence of her horrific new diet.

She serves as a roaming threat throughout the facility, representing the personal horror of what any survivor could become if exposed to the wrong combination of experimental compounds. Her presence forces players to confront not just external dangers, but the possibility of their own corruption and transformation into something monstrous.
