Bebilith

A bebilith, otherwise known as a creeper of the Abyss or barbed horror, was an arachnid tanar'ri demon that for its own inscrutable reasons preyed upon other demons. Their kind often roamed the Abyss unimpeded as their strange mystique caused other demons to leave them alone.

Description
Bebiliths looked like massive, misshapen spiders, with a body the size of a plow horse and legs stretching some 14 feet (4.2 meters). A tough, chitinous exoskeleton covered their two ton (1814.3 kilograms) forms. Their two forelegs ended in razor sharp barbs, and their fangs dripped globs of odorous liquid. They were seemingly incapable of speech, conducting all their communication in silent telepathy.

Personality
While some accounts of bebilith behavior claimed they hunted other demons for the fun of it, others purported that they were punishing them. Their targeting system was inexplicable and once they decided on a a group to exterminate they would not stop until its utter obliteration. It was especially confusing given how almost all tanar'ri were beings of such complete moral bankruptcy, that they had specific targets. While not stupid their intellects were limited, furthering the incomprehensibility of their actions.

Combat
These claws were used to penetrate and rip armor plating from the bebiliths' foes. Just as with spiders, bebiliths had a lethal bite, but rather than a venom (to which demons were immune), they injected a vile fluid, a necrotic liquid that caused accelerated rotting of the flesh.

Bebiliths were incredibly aggressive and would attack anything they saw.

History
Bebiliths originated from the realm of Lolth.
