Hamatula

Hamatulas, also called barbed devils, were the guardians of the Nine Hells, entrusted with important duties such as defending infernal fortresses or prisons, guarding vaults, and serving as bodyguards to the most powerful denizens of the Nine Hells.

Description
As their name implied, a barbed devil was covered in a mass of sharp barbs. Their hands ended in long, razor-sharp claws. A barbed devil was about 7 feet tall and weighed about 300 pounds. Barbed devils were constantly alert and were not easily surprised.
