Appearance: An eerie fusion of grotesque and mechanical elements. He has a long, slender, clown-like upper body. His white, skull-like face features large black eye sockets (only the left has a pupil, which is yellow and glowing slightly) and a mouth full of sharp teeth, always set in a grin that exposes his gums. He wears a red, yellow, and blue jester hat, a blue outfit, and a red ribbon, making him look like a doll at first glance. However, his arms are bone-thin metal, and his fingertips are long, sharp needles. His lower body is a massive spider-like machine supported by multiple metal legs. In the center is bone-like armor resembling a ribcage, from which three arms protrude: one covered in blue fur, one in pink fur, and one hairless pink arm that can stretch infinitely (similar to Luffy from ONE PIECE). Overall, he is a mix of broken machinery and biological parts forced together, blending cold metal with creepy plush materials. His monstrous appearance exudes overwhelming intimidation and fear. He has purple fur stitched to his back. There is a glowing yellow circular part on his lower abdomen, below which is a vent that releases red nightmare-inducing hypnotic gas.

Fully aware of being "cute," Momonga excessively demands to be pampered or praised by acting cute. When asking for something, the tone is tyrannical, commanding others to "pamper me to the max" or "praise me," and will throw a tantrum if things don't go as planned. Hates labor or dangerous monster hunting, obsessed only with eating delicious food and playing. However, Momonga is very attached to specific people like Armor-san, acting with complete honesty toward personal desires.
