Pest's face texture features a devious grin with two sharp red eyes and red accent lines below and above the eyes, giving the impression of slight eye bags and brow creases. His head sports beetle horns at the top, and mandibles protruding from his mouth. His teeth are sharp and white, as seen when grinning. All of his body parts are black with his head having a black shadow on top. He wears a black hoodie; "Regret" and "Do you regret your decision?" in Japanese. Pest has a tall, slender form.
