The monstrous man appearance of the moth experiment, with its wings dragging on the ground, is a chilling sight. Its wings, resembling tattered, leathery membranes, are covered in a grotesque mosaic of scales that shimmer in an eerie bioluminescent glow. The creature's elongated, hunched body is adorned with twisted, jointed limbs that end in sharp, claw-like appendages. Its head is dominated by bulbous, multifaceted eyes that gleam malevolently in the darkness. The moth experiment's overall visage exudes an unsettling blend of fragility and menace, as if it's ready to take flight into the realm of nightmares.
