Male Demon Names: 100 Brutal & Infernal Ideas for Fantasy

A male demon's name should feel like it was scratched into stone in a language humans were never meant to read — brutal, infernal, and ancient, thick with hard consonants and the grand menace of something that's been collecting souls since before your gods were born. Demon men in fantasy are demon lords and warlords, infernal princes and brutal fiends: proud, hungry, and dangerous, ruling burning kingdoms or rampaging across the mortal world. His name needs that harsh, dread quality — growling and grand, often grimoire-flavored, the kind of name carved above the gates of a burning city. Where an angel's name soars, a demon's name drags — down, into smoke, shadow, and fire.

The appeal of male demon names is the menace plus age. He might be a mighty demon lord, a brutal war-fiend, an ancient infernal prince, or a scheming deal-maker — and the name should sound harsh, ancient, and powerful, often paired with a dread title that hints at how he tricks, rules, or destroys. The harder and more grimoire-authentic it sounds, the more terrifying the demon.

Below are 100 male demon names — brutal and infernal — sorted by style, plus titles and a quick how-to. Whether you're naming a world-ending archfiend, a brutal warlord, or a scheming infernal prince, there's a suitably sinister name here. Don't read them aloud three times. Tips at the end.

Demon lord & infernal prince names

Grand, ancient, and terrible — these suit demon lords, infernal princes, and archfiends of dread authority:

Malphas, Abaddon, and Asmodaeus carry genuine grimoire weight (they echo names from real demonology, which is why they ring so authentically infernal). Abaddon literally means "destruction," and Xaphan (a demon said to stoke the fires of hell) suits a lord of the infernal forges — names dripping with dark authority.

Brutal & savage demon (war-fiend) names

For brutal war-demons and savage fiends — harder, blunter names built for destruction:

Vorgath, Karrnoth, and Brakthul lean into pure brutal destruction — harder and blunter than the scheming lords, with growling consonants that promise violence. These suit war-demons, siege-fiends, and savage horrors that rampage rather than scheme — the kind of demon your heroes fight with steel, not words.

Lesser demon & imp names

For lesser fiends, imps, and summoned horrors — shorter, sharper, nastier names for the smaller terrors:

Grix, Skarn, Vurk, Nix, Crule, Gnash, Vexil, Skritch, Maug, Zann, Snarl, Vryk, Pox, Crege, Snik, Gorr, Mavlik, Krell, Drix, Hagor.

Grix, Skarn, and Gnash are perfect lesser-fiend names — short, ugly, and quick to say (which suits things that move in swarms). These suit the imp bound to a warlock, the lesser demon doing a lord's dirty work, or the horror your party fights on the way to the real archfiend.

Demon titles & infernal epithets

Demons love a grandiose title almost as much as a name — stack one on for instant dread:

the Devourer, the Unspoken, Lord of Ash, the Soul-Eater, the Pit-Born, Prince of Lies, the Hollow King, the Bringer of Ruin, the Crimson Hunger, Master of the Burning Throne, the Thousand-Eyed, the Faceless, Keeper of Broken Oaths, the Wormtongue, the Defiler.

A title turns a name into a legend: Malphas, Prince of Lies; Abaddon, the Bringer of Ruin; Vorgath, the Devourer. Demons are obsessed with status and dread, so a fitting epithet — especially one hinting at how he tricks, rules, or destroys — does a ton of storytelling in just a few words.

How to name your demon

Menace, age, and harsh infernal grandeur:

• Use hard, harsh sounds. Growling R's, hissing S's, hard K/G/X/Z — Vorgath, Skarnax, Xaphan, Grix. The name should feel rough and dangerous in the mouth.
• Borrow from demonology. Malphas, Abaddon, Asmodeus, Valefor, Baphomet come from real grimoires, which is exactly why they ring so authentically infernal.
• Scale the name to the demon. A world-ending archfiend gets a grand, multi-syllable name (Asmodaeus, Belphemor); a brutal war-fiend gets something blunt (Vorgath, Karrnoth); a lesser imp gets something short and nasty (Grix, Nix).
• Add infernal endings. "-oth," "-eus," "-as," "-ax" give that ancient demon-lord ring (Azkaroth, Mortheus, Malphas, Skarnax).
• Crown it with a title. "the Devourer," "Prince of Lies," "Lord of Ash" — demons adore dread-soaked epithets, and they make any name legendary.

A great male demon name should feel genuinely uncomfortable to say — like the syllables themselves are sharp, and speaking it might attract attention you don't want. Lean into the harsh, grimoire-authentic sounds, scale it to the demon's power, and crown it with a dread title, and your demon will feel every inch the ancient, hungry, infernal terror he is.

Match the name to the demon's domain

Male demons fill several infernal archetypes, and matching the name to his domain and role makes him far more menacing. The classic is the demon lord or infernal prince — the grand, ancient ruler of a burning kingdom or layer of hell, proud and scheming, commanding legions of lesser fiends, suiting a grimoire-grand name (Malphas, Abaddon, Asmodaeus) and a dread title (Prince of Lies, Lord of Ash). The name should sound like it's carved above hell's gates. Then there's the brutal war-demon or warlord — the savage fiend of destruction who rampages rather than schemes, fitting a blunt, growling name (Vorgath, Karrnoth, Brakthul) and a violent title (the Devourer, the Bringer of Ruin).

There's also the scheming deal-maker or tempter — the cunning demon who destroys mortals with contracts and whispers rather than claws, suiting a smooth, sinister name (Valefor, Nerathul) and a sly title (Prince of Lies, Keeper of Broken Oaths). And there's the lesser fiend or imp — the small, nasty terror doing a lord's bidding or bound to a warlock, fitting a short, ugly name (Grix, Skarn, Gnash). Don't forget the ancient elder demon either — a primordial horror so old it predates the infernal hierarchy (Azkaroth, Dis), suiting a vast, archaic name. Deciding which kind of demon he is — lord, warlord, schemer, lesser imp, or ancient elder — and his domain (lies, war, decay, fire) instantly tells you how grand, how brutal, or how nasty the name should be. Pick the domain, harshen the sounds, add a title, and your demon will feel like a true infernal power rather than a generic horned monster.
