Our resident obscure Devil Lords, the lesser-known Dukes of Hell, were also very popular on the poll. I do not have any pictures of them (with the exception of Glasya who is in the original Monster Manual II). They originated in Dragon Magazine #75-76.
Alastor
Alastor the Grim, the greatest pit fiend of all, serves Asmodeus as Hell’s executioner. It is said that if the Hell’s were swept away and Asmodeus could choose but one devil as a companion, that it would be neither consort nor lieutenant, but Alastor the Grim.
Alastor appears as a normal pit fiend standing about 16 feet tall. His body is scarred and his wings are broken. Alastor never speaks.
Baalberith
The great pit fiend Baalberith acts as the Major Domo of Asmodeus’ palace in Nessus. He leads a small detail of eight pit fiends that safeguard the Keeper of the Records, Adramalech, at the behest of Asmodeus. Neither Adramalech nor Baalberith are pleased with this arrangement, as there is no love lost between them. Both keep their true feelings hidden, however, for fear of repercussion by the Overlord of Hell.
Baalberith appears as a normal pit fiend.
Baalzephon
The great pit fiend Baalzephon is the Prime Minister of Dis, leading the vassals and armies of Dispater. He is almost always found in Dispater’s palace or at the right-hand of the arch-devil himself.
Baalzephon appears as a normal pit fiend.
Caarcrinolaas
Caarcrinolaas appears as a gray-brown furred humanoid with a dog’s head and yellow eyes. He has scarlet bat-like wings and upright, scarlet horns. His hooves are black and his forked tail is scarlet. In the center of his brow is a third horn. Taller than the other two, it stands straight up, and Caarcrinolaas can use it in combat, though he rarely, if ever, does. He wears +3 chainmail.
Focalor
Focalor appears human—a thin, bearded, and middle-aged sage with power and heavy concerns—until he unfurls his feathered wings from his flowing robes or reveals his brown cloven hooves. He wears an iron gauntlet on his right hand as his badge of office.
Melchon
Meclhon stands 6 feet tall and appears as a red skinned humanoid with upturned, bull-like horns; black, curling brows and beard. His hooves are black and he has large crimson wings.
Zimmimar
The great pit fiend Zimmimar leads 6 companies of osyluths in the service of Mammon. He serves as “protector” of Mammon’s palace on Minauros, and is thus almost always found there, or in the company of Mammon himself. Zimmimar does not like nor trust Bael or Focalor, though he keeps his suspicions to himself.
Zimmimar appears as a normal pit fiend.
Baalphegor
Baalphegor is a very beautiful cinnamon-brown skinned devil standing about 6 feet tall. Her eyes are the color of rubies and her small, leathery wings are black in color. She has no horns, but sports a small, slim forked tail. By folding her wings against her back and hiding her tail, she can pass for an exquisitely beautiful human.
Glasya
Glasya, as consort to Mammon, is one of the most influential and powerful of female devils. The fact that she is also the daughter of Asmodeus, the ruler of the Hells, strengthens her influence among the devils. She appears as an incredibly beautiful female with coppery skin and green eyes. Large bat-like wings protrude from her shoulders, and two small horns sit above her eyes.
