Belhemous is a huge snake-like dragon made of dark metal covered with glowing green lines. Its body consists of 6 parts: the head, the tail, and 4 identical middle parts that each hide a weak point. It has two pairs of upper and lower jaws, and several rows of pointy teeth. It has a bright white crystal on its forehead, that reveals its weak points when hit.
Belhemous can fly in the air, and also move under the sand. It can launch homing missiles out of its mouth.
- The music heard during the Belhemous fight, Danger Lurking, uses quick, high pitched violin notes, and, along with the fight's concept of a drawn out battle against an enormous, sharp-toothed beast, seems to be a nod to the 1975 film Jaws.
