Hell gigas are gargantuan giants of enormous strength and heat who wear a second skin fashioned of bone, muscle, and iron that serves as armor. These creatures are covered in scars and wounds from innumerable battles. A hell gigas generally stands about 50 feet high and weighs at least 20 tons.
Habitat and ecology
Most hell gigas dwell in the mountains and wilderness of Avernus, Phlegethon, and outside the city of Dis, in fiery demesnes running with lava in which they can focus on their petty tyrannies over lesser devils and lost souls. Hell gigas hate fire giants, but delight in enslaving them. Although they live in Hell, hell gigas avoid devils to avoid entanglements with the infernal hierarchy.
