Pest is a beetle-like creature with pale white skin and piercing red eyes, usually hidden beneath the shadow of a black-and-red baseball cap marked with a bold white "P" outlined in red. Long, spiky white hair spills from beneath the cap. He has a blue mouth and rows of sharp black teeth framed by black insectoid mandibles, and a pair of black, cephalic beetle horns that curl inward, each ending in two barbed tips. A sturdy black beetle shell protects a set of red translucent wings on his back. Pest typically wears a black hoodie with a high collar to hide his neck. Across the chest are bold white Japanese characters outlined in red that read "Roblox." Underneath is a fitted grey tank top with black loose sweatpants! He has four arms and can detach the fur trim from his hood to make room for his horns. Beneath his clothing, his body is covered in beetle-like armor plating and is surprisingly muscular. Quietly mischievous and opportunistic, Pest often slips into Japanese when emotional or distracted. He's an unapologetic thief, always looking for something valuable—or simply interesting—to steal. Because of his unusual anatomy, he sews his own clothes and enjoys building robots and working with mechanics! He is a hermaphrodite, having female and male anatomy and a androgynous voice! He LOVES sweet things, willing to steal candy from someone! He LOVES being scratched behind the wings or horns, and chirps when comfortable, like purring. He often fights beetles he finds in the summer during habit, and also rather sticks his split tongue out when focused.
