The Three Prime Evils (Art from Diablo)

Seven is the number of the powers of Hell, and Seven is the number of the Great Evils. Seven Evils spawned from seven heads. Seven realms birthed from death. Infested, unending, cycles upon cycles.
Adria, a servant of Al'Diabolos.

The Great Evils, also known as the Greater Evils, are the seven powerful Demon Lords that rule over the Burning Hells.


The Great Evils once ruled all of Hell before being defeated by Mundus and his knight Sparda after the former wish to unite Hell under his control. They are sub-divided into the three Prime Evils, and the four Lesser Evils. Even if they are brothers, the Great Evils always waged wars against each other, destroying entire realms in the process.


The Prime Evils, who held absolute power over all of hell, and thus over the Lesser Four. They were both respected and feared by their minions and enemies. Although they were back-stabbed by the Lesser during the Dark Exile, they later used their help in the mortal plane.

The Lesser Evils controlled their own Domains in the Burning Hells, but were always striving for more power. Belial and Azmodan united themselves to overthrow the Prime Evils, in a battle that became known as The Dark Exile. It was later revealed that this was actually a plan to obtain the power of the Soulstones, in order to enter the mortal plane with their full power, as Andariel and Duriel were acting on the Three's behalf.



They were created by from the seven heads of the Progenitor Tathamet. A seven-headed dragon god composed of all darkness and vileness that God cast off itself during the beginning of Creation. It is known that he was the only reason that the Burning Hells came into existence. Tathamet had battled one of God's avatar, Anu and died against him with his seven heads becoming the seven Great Evils.

Tahameth 2.png Tathamet The Prime Evil A seven-headed dragon composed of all darkness and vileness that God cast off itself before the universe was created. Tathamet battled Anu, and when the two beings died the seven heads of Tathamet became the seven Great Evils. The three most prominent heads became Al'Diabolos, Dul'Mephistos and Tor'Baalos, and the four lesser heads Azmodan, Belial, Andariel and Duriel.

Prime Evils

The three most prominent of Tathmamet heads became the Prime Evils. The Prime Evils comprise the Three Brothers which are the rulers of the Burning Hells.

Image Name Aspect Description
Mephisto2.png Dul'Mephistos (Mephisto) Lord of Hatred
Spirit of Love (as Mephis)
The oldest of the Three Brothers. Father of Lilith and Lucion. Arguably the most intelligent and cunning demon in existence, though physically the weakest of the three brothers.
Diablo2.png Al'Diabolos (Diablo) Lord of Terror
Spirit of Determination (as Dialon)
The youngest of the Three Brothers. Generally uses fire, lightning and physical. He is believed to be the most dangerous of them all and has been described by Cain as an "artist of terror" who enjoys sowing fear into people's hearts the way a painter would make brushstrokes.
Baal2.png Tor'Baalos (Baal) Lord of Destruction
Spirit of Creation (as Bala)
The middle child of the Three Brothers. His attacks are mostly magical and of an assorted variety, likely due to having Tal Rasha as his host. Due to his corruption of it, he was also indirectly responsible for the destruction of the Worldstone.

Lesser Evils

The four lesser heads of Tathmamet became the Lesser Evils. The Lesser Evils are second only to the Three Brothers in terms of power and prestige but are nonetheless beneath them.

Image Name Aspect Description
Andariel2.png Andariel Maiden of Anguish
Demon Queen
"Twin" sister of Duriel. Sent to guard the Rogue Monastery by Al'Diabolos himself. Her second title is a reference to being the first female demon in existence. She specializes in mid range poison attacks and is capable of killing a human in melee quickly but is ridiculously weak against fire spells. She is the first of the Lesser Evils to be defeated.
Duriel2.png Duriel Lord of Pain
Maggot King
"Twin" brother of Andariel. Though Duriel had his part in the Dark Exile, he has once again aligned with the Three. Sent to guard Tal Rasha's Chamber. His secondary title is a sobriquet pertaining to his status and appearance as a monarch among a certain kind of insect. Specializes in heavy melee attacks and radiates the grave chill. He is the second of the Lesser Evils to be defeated.
Belial2.png Belial Lord of Lies
Master of Deception
One of the leaders of the rebellion against the Three and a former protégé of Dul'Mephistos. He somehow comes to take over Caldeum and controls its Emperor. Uses unholy locust swarms for both phases of his fight with heroes: on the 2nd phase, he'll dig his massive claws into the ground, breathe huge gusts of fel locust flame and make fiery eruptions. His powers are so great that he manages to fool everyone (including himself) into thinking that he is invincible. He is the third of the Lesser Evils to be defeated.
Azmodan2.png Azmodan Lord of Sin
General of Vices
One of the leaders of the rebellion against the Three. Brother and rival of Belial. Throws fire boulders, summons demon gates to call upon minions and call forth dark magic in a large area of effect. He is the greatest military tactitian in the Burning Hells, although such a claim is very much in doubt considering his arrogance and repeatedly telling his enemies his next plan is what cost him his victory during the Battle of Bastion's Keep and Arreat Crater. He is the fourth of the Lesser evils to be defeated and the last Great Evil to be sucked into the Black Soulstone.


They are ancient demons, rulers of the Burning Hells where only the worst of demons and the cruelest of sinners are damned to. Rumors said that they're scheming to overthrow Lucifer and take over hell, but their plans always fail because of internal conflict.
