"Seven is the number of the powers of Hell, and Seven is the number of the Great Evils."


The Great Evils (a.k.a. Greater Evils)[1] are the seven most powerful demon lords of Hell. They are sub-divided into the three Prime Evils, and the four Lesser Evils.


"Seven Evils spawned from seven heads. Seven realms birthed from death. Infested, unending, cycles upon cycles."


The Great Evils waged wars against each other, destroying entire realms in the process.[2]

Tahameth 2
Tathamet The Prime Evil A seven-headed dragon composed of all darkness and vileness that Anu cast off itself before the universe was created. It is known that he was the only reason that the Burning Hells came into existence. 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 Diablo, Mephisto and Baal, and the four lesser heads Azmodan, Belial, Andariel and Duriel. Tathamet's body meanwhile became the foundation for the Burning Hells.

Prime Evils

The Prime Evils comprise the Three Brothers - the de facto rulers of Hell:

Mephisto -


Lord of Hatred

Spirit of Love (as Mefis)

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. His attacks in Diablo II are generally lightning and poison based, which are further compounded by assistance from corrupted Councilmembers.
Diablo -


Lord of Terror

Spirit of Determination (as Dialon)

The youngest of the Three Brothers. Father of Leah. Generally uses fire, lightning and physical in Diablo II. As the main antagonist of the series, 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.
Baal -


Lord of Destruction

Spirit of Creation (as Bala)

The middle child of the Three Brothers. His attacks in Diablo II 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 Lesser Evils are second only to the Three Brothers in terms of power and prestige but are nonetheless beneath them:

Andariel Maiden of Anguish


Demon Queen

"Twin" sister of Duriel. Sent to guard the Rogue Monastery by Diablo 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 hero in melee quickly but is ridiculously weak against fire spells. She is the first of the Lesser Evils to be defeated.
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.
Belial Lord of Lies


Master of Deception

One of the leaders of the rebellion against the Three and a former protege of Mephisto. 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.
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.
