Archdevil

The archdevils were the rulers of the Nine Hells. They were also called the Lords of the Nine, the Archdukes of Hell, and the Lords of Hell. They each controlled one of the plane's nine layers and were the most powerful and highest-ranking devils. Unlike the chaotic evil demon lords of the Abyss, the Lords of the Nine (and all the baatezu of the Hells for that matter) were arranged in a strict hierarchy. The lord of the first layer had the lowest rank of the nine archdevils, while the lord of the ninth layer had the highest rank. While the demons of the Abyss answered only to their own basic instincts, every single devil, at least in theory, answered to the Lord of the Ninth, Asmodeus.

Each archduke was a unique devil of immense power and influence, with his own resources: military, magical, and political, to rely on in the endless scheming that characterizes devilish politics.

Lord of the First: Zariel the Warlord
A former angel, Zariel the Warlord ruled Avernus, the first layer of Baator. She is also the lead general in the Blood War.

Lord of the Second: Dispater, The Iron Duke
The Lord of the Second, Dispater, appears as a tall humanoid with dark hair, tiny horns, and a single cloven foot (the other foot is normal). He always dresses well and carries the badge of his office, a rod of great power. He is also paranoid and rarely leaves his Iron Tower in his layer of Dis.

Lord of the Third: Mammon the Viscount
Mammon rules the layer of Minauros. He resembles a thirty-foot-long serpent with a humanoid upper body. He is duplicitous and considered untrustworthy by the archdukes. Mammon represents greed and lust for treasure.

Lords of the Fourth: Lady Fierna and Archduke Belial
Fierna and Belial rule Phlegethos, the fiery fourth layer of Baator, jointedly- in a way. Fierna is the official ruler, while her husband, Belial, makes the decisions. Both husband and wife resemble sensual humans with small horns and glowing red eyes.

Lord of the Fifth: Prince Levistus
Levistus appears as humanoid male with pale skin, black hair and entirely black eyes, and pointed teeth. However, he was imprisoned in iceberg by. After Geryon, the former ruler of Stygia, was nearly deposed, the Lord of the Ninth appointed Levistus as the new Lord of the Fifth, but did not release him for a while. Thus, Levistus was forced to transmit all instructions telepathically to his minions.

Lord of the Sixth: The Archduchess Glasya
The Archduchess Glasya is the daughter of Asmodeus and rules the layer Malbolge. She appears as a supremely beautiful humanoid with copper skin, wings, a forked tail, and small horns.

Lord of the Seventh: Baalzebul the Lord of Flies
Also called the Lord of Lies, the Fallen One, and the Slug archduke, Baalzebul rules the seventh layer of Baator, Maladomini. He has an angelic body but when he lies to be a devil, Baalzebul changes into a slug-like form.

Lord of the Eighth: Mephistopheles, Archduke of Cania
Mephistopheles, the ruler of Cania, is a tall humanoid with red skin, wings, and horns. He is often confused with Asmodeus by mortals, a fact that frustrates him to no end and amuses Asmodeus. Despite having failed Asmodeus, he was not demoted out of rulership.

Lord of the Ninth: Asmodeus, Supreme Ruler of the Nine Hells
Asmodeus, the sumpreme ruler of the Nine Hells and the Lord of the Ninth, was the most powerful archdevil. He is also a god of sin and order. Asmodeus rules the layer of Nessus. He appears as a handsome, thirteen-foot-tall human with black hair, crimson eyes, and small horns. Underneath his finery, though, constantly bleeding wounds cover his skin.
