Beelzebub is a tall, fox-like demon with insect-like features, such as multiple arms, a pair of antennae attached to her ears, and a small pair of insect wings. She has yellow and pink-striped fur, and black markings that give a dripping appearance down her four arms and digitigrade legs. Her hair and tail seem to be made of either honey or lava lamp fluid and glow bright pink, blue, and orange, with her stomach also being a lava lamp. She has a pink stripe on her head that opens up into a third eye when she enters her full demon form. Her outfit consists of a black choker around her neck, a pink off-the-shoulder crop-top with a heart-shaped cutout, white markings underneath turning into a paw with claws, a black low-cut bra, and a pair of lighter pink short shorts with trim the same color as her top.
