People belonging to the Ultramarines, both on the Tabletop game, the animated film, and in the novel series by Graham McNeill.
One of the twenty Primarch created by the Emperor of Mankind, he and his brothers were scattered to the stars by the Chaos Gods to preventing the coming of the Imperium. Landing on Macragge, the boy was found by Konor Guilliman, one of the two Consuls of Macragge, who named him Roboute and raised him as a son. Quickly growing to manhood, Roboute helped to pacify Macragge's wild men. After returning from a campaign, Roboute found that his father's co-consul had launched a coup and killed Konor over his anti-aristocratic policies. Roboute avenged his adoptive-father and became sole Consul of Macragge, rewarding those who showed merit and skill and ignoring aristocratic privileges. By the time the Emperor found Macragge, Roboute had ruled for five years and established an alliance of mutual aide with eight other star systems, forming the future realm of Ultramar. Roboute was made commander of the XIII Legion of the Adeptus Astartes, redubbed the Ultramarines.
During the Great Crusade, the Ultramarines and the Luna Wolves were the largest and most efficient of the Space Marine legions. However, Guilliman earned the eternal hatred of Lorgar of the Word Bearers when the Ultramarines were ordered to destroy the city of Monarchia as part of the Emperor's rebuke of Primarch Lorgar spreading the Cult of the Emperor. The Word Bearers would launch a surprise attack on Calth, but were eventually repulsed, delaying Guilliman from reinforcing the Emperor at the Siege of Terra. As his Legion suffered few losses during the Horus Heresy, Guilliman emerged as the most powerful Primarch in the aftermath of the Emperor's ascension to the Golden Throne. Assuming the post of Lord Commander of the Imperium, Guilliman formed the High Lords of Terra to rule in the Emperor's name and published the Codex Astartes, breaking down the nine loyalist legions into one thousand strong chapters. During a battle with the fallen Primarch Fulgrim of the Emperor's Children, Guilliman was slashed across the throat. He was placed in a stasis field and placed in a shrine on Macragge, where pilgrims visiting hold that he is healing.
In the 8th edition of the tabletop game, he was finally returned to life after twenty five years of teasing. He proceeded to launch a century-long campaign of non-stop conquest, driving back the daemons and opportunistic aliens that had been preying on the nearly-bankrupt Imperium since the successful 13th Black Crusade.
- Aristocrats Are Evil: Guilliman's back story has this. His adoptive father's rivals, specifically.
- Badass Boast: In Know No Fear:"What does not kill me is not trying hard enough."
- Badass Bookworm: He did found a lot of libraries.
- Badass Bureaucrat: Organisation was his strong point. The Emperor and even his brothers considered him the galaxy's best logistician. When Konrad Curze captured Vulkan, Guilliman raising an army to defeat Curze was Vulkan's first thought. His Indomitus Crusade brought more of the galaxy back under human control than any war the galaxy had seen in nine thousand years.
- Badass in Charge: Outright refuses to be an armchair general, and takes to the field all the time. By the time of Know No Fear, Lorgar's men consider him the seventh or eighth best swordsman in the entire Imperium of several trillion.
- Big Book of War: The Codex Astartes.
- Cultured Badass: You bet. Quotes Hamlet, can identify string instruments by their tone, and can punch through eight feet of solid concrete.
- Hollywood Tactics: See Big Book of War. Thing is, unlike most Hollywood Tactics, it actually contains tons of useful advice. The problem is that it also hasn't changed in ten thousand years, while everything else did.
- Four-Star Badass: He briefly held a military rank after the Emperor was enthroned that only the Emperor himself could revoke: Lord Commander Militant of the Imperium.
- Jerk with a Heart of Gold: Guilliman may have been autocratic and personally unlikable (sometimes, he was fine when he wasn't mad about something) but he actually cared about the common people, believing anyone could rise to greatness regardless of social status.
- King in the Mountain: His body is perfectly preserved in a stasis field in the Ultramarines fortress-monastery, where pilgrims insist that he is healing. Many point out that this is impossible, but those who insist he is healing ascribe it to the power of the Emperor. It says something about the Imperium that the doubters concede that this is a good point. It says something about the setting in that the fans also believe this is a good point.
- He's Back: In Gathering Storm.
- Heartbroken Badass: You can feel the pain when reading his words about how far the Imperium has fallen:"Why do I still live? What more do you want from me? I gave everything I had to you, to them. Look what they have made of our dream. This bloated, rotten carcass of an empire is driven not by reason and hope, but by fear, hate and ignorance. Better that we had all burned in the fire of Horus' ambition than lived to see this."
- Hope Bringer: Desperately needed in the closing days of the 41st millennium.
- Power Fist: The Gauntlets of Ultramar.
- The Good King: The Eldar themselves decided he was the best option as a new ruler for Mankind who may be capable of joining forces with them to fight Chaos, it speaks volumes of Guilliman's virtues as a ruler that the Eldar have such a good opinion from a (super)human.
- Slashed Throat: Courtesy of Fulgrim. It must have been a hell of slash to endanger the extremely tough and massively redundant biology of the god-like Primarchs, not to mention the massive healing factor he must have. On top of that, consider that the enormously potent medical science of the Imperium was unable to save him. And despite the Imperium's technological atavism, their medicine must still be enormously advanced, especially considering they'd almost certainly break out all the good stuff they don't have the resources to provide to all one quadrillion humans for a literal son of their god. And people insist it's healing.
- The Strategist
Marneus Augustus Calgar
Marneus Augustus Calgar is the Chapter Master of the Ultramarines and Lord of Macragge, leading both the Ultramarines and the realm of Ultramar. He has served in this position for over three hundred years.
- Cyborg: Older editions state that he lost all four limbs and most of his body during the First Tyrannic War, leading him to replace them with augmetic limbs and a bionic eye.
- Dark Secret: He told the Ultramarines that he banished Mkar, when it reality he merely imprisoned the daemon in the Indomitables warp core. When the truth comes out, the Ultramarine captains are shocked that Marneus Calgar lied to them about something so important.
- My Greatest Failure: Failing to kill M'kar, and simply binding it in the Indomitable.
- And failing to stop Hive Fleet Behemoth from slaughtering the Entire First Company during The Battle of Macragge.
- Nice Guy: Hell yes, especially by Imperial standards.
- Nice to the Waiter: Will treat you with dignity and respect, whether you are a Marine, a Lord, or even a Common Human Serf.
- Reasonable Authority Figure: Not always, but the majority of the time. He's also one of few First Founding Chapter Masters who is willing to tolerate not being the highest-ranked person in a given room.
- Retcon: Older editions of the game stated that he was captured by the Tyranids as a child before being found and recruited by the Ultramarines, while more recent editions state that was already Chapter Master of the Ultramarines by the time the first Tyranid hive fleets appeared.
The Chief Librarian of the Ultramarines. So far he is the only psyker in the Imperium who has been able to make contact with the Tyrannid Hive Mind.
- Incendiary Exponent: The Hood of Hellfire, which amplifies his psychic powers and gives an appearance that his head is on fire.
- Psychic Powers: He's a Librarian. Interestingly, he also seems to be able to read the same skeins of fate that some Eldar can, and used the ability more than once during the Dark Imperium.
- Sole Survivor: The only psyker who has been able to make contact with the Tyranid Hive Mind and survive the experience.
- "Praise the sun that brings the dawn of our final doom."—Captain Invictus Famous Last Words
Captain Saul Invictus commanded the Ultramarines 1st Company when it was destroyed in the defense of the polar fortresses in the Battle for Macragge, during the First Tyrannic War.
- Last Stand: He and the First died holding the northern polar fortress against the Tyranids.
- Meaningful Name: His name means "The Unconquerable Sun".
- Number Two: As Captain of the First Company.
Captain of the First Company, and by virtue of his post Regent of Ultramar. Former Captain of the Second Company, he was promoted to First Captain after the Battle of Macragge saw the death of the entire First Company.
- Ascended Extra: One of the default models for an Ultramarines First Company Captain is now confirmed to be Severus.
- Number Two: Officially, as First Captain...
- Passed-Over Promotion: ...but Calgar's more likely successor is Sicarius. Which doesn't please Agemman at all.
- The Rival: With Sicarius..
- Reasonable Authority Figure: Actually sympathized with Uriel's decisions over violating the Codex Astartes, but realised that the Codex is needed to keep them on the straight and narrow, or risk becoming like Chaos Space Marines.
- The Stoic: Unless you do something to dishonour the Ultramarines or the First Company, in which case he gets really emotional.
- You Are in Command Now: Of the First Company. Still in command of most of its assets after Guilliman got off the Throne of Corrections.
Captain of the Second Company, he was promoted to his position after Agemman was promoted to First Captain.
- BFS: His Tempest Blade.
- Beyond the Impossible: He killed what amounts to a god, in single combat; a Transcendent C'tan By cheating and using a Vortex bomb.
- Glory Seeker: Some suspect him of this in trying to succeed Marneus Calgar as Chapter Master. He's pretty defensive about such implications, though.
- It's Personal: His dislike of Ventris is due to blaming him for the death of Idaeus who Cato served as Champion.
- My Greatest Failure: the fall of Damnos.
- Names to Run Away from Really Fast: "Sicarius" in High Gothic translates to "man of the sicae". Sicae means a small dagger, the sort that could be concealed and carried within the Imperial City, where bearing arms was restricted to the Emperor and his agents. Colloquially, the best translation is "assassin" or "terrorist".
- The Rival: With Agemman.
- Sword and Gun: A simple plasma pistol in one hand, the Tallassarian Tempest Blade in the other.
- Try to Fit THAT on a Business Card!: Cato Sicarius, Captain of the Ultramarines Second Company, Master of The Watch, Knight Champion of Macragge, Grand Duke of Talassar, High Suzerain of Ultramar, and Master of the Household.
The Master of Sanctity (head of the Chaplaincy) of the Ultramarines. Having served in the position for over four hundred years, he is one of the few people who can still refer to Lord Calgar as "young Marneus".
- Absolute Xenophobe: Part of his job, but he has a special hatred of the Tyranids. Not surprising, given what the Tyranids did to Ultramar.
- Drop the Hammer: His Crozius Arcanum.
The Veteran Sergeant of the 10th Company, having served under three Chapter Masters and many of the Chapter's greatest heroes.
The Protagonist of the Ultramarines novels by Graham McNeill. He became Captain of the 4th company after the death of his predecessor, Idaeus.
- The Atoner: For violating the Codex Astartes on Tarsis Ultra.
- Country Mouse: Being from Calth makes Uriel seem unsophisticated in the eyes of Macragge natives like Learchus, which contributed to the friction between them when they were aspirants.
- Electronic Eyes: After surviving a shot to the head by the Newborn, all he gets for it is a shiny new bionic eye.
- Field Promotion: Received one from Idaeus, which was confirmed by Calgar.
- Heroes Prefer Swords: Uses a power sword.

- It Was a Gift: His power sword was previously wielded by his predecessor, Idaeus.
- Made of Iron: Even by Space Marine standards Uriel has the habit of surviving things which should outright kill him. These include being shot in the face at point blank range, being tortured by the Iron Warriors and having all the blood in his body simultaneously clot.
- Nice Job Breaking It, Hero!: Partially responsible for unleashing the Nightbringer back on the galaxy. And for your information, the Nightbringer is the entity who instilled the fear of death in sentient beings at the dawn of creation.
- Suicide Mission: Is sent on a death oath to destroy daemon wombs on Medrengard. And succeeds.
- Was It Really Worth It?: Asks himself this after meeting a normal Guardsman on Tarsis Ultra, in giving up the chance of a normal life, and decides that yes, it was.

- The Rival: With Uriel when they were Aspirants.

- Would Not Shoot a Civilian: Came within a hair's-breadth of killing an inquisitor for wiping out a planet of innocent civilians to slow the Tyranid Invasion in Warriors of Ultramar.
- You Are in Command Now: Was made Master of the Fleet, a title which would have gone to Uriel.
Chaplain of the 4th Company.

The Apothecary of the 4th Company.
- Combat Medic: As most Apothecaries are.
- Deadly Doctor: Uriel notes that his knowledge of the body's weak points makes him very dangerous.

The former Captain of the 4th company, and mentor of Uriel Ventris.
- BFS: Wielded a power sword which he gave to Uriel before his death.
- Combat Pragmatist: Unique among the Ultramarines, Idaeus considered the Codex Astartes to be a guide for Space Marines, and not something they were to follow by route.
An Adept of the Administratum, sent to assess Pavonis's inability to pay its tithes to the Imperium. Secretly a member of the Inquisition.
- Obstructive Bureaucrat: Subverted, as he's not obstructive. And he's not a bureaucrat.
- Reasonable Authority Figure: Even for a member of the Inquisition, he's willing to perhaps sacrifice any opportunity to take down the Nightbringer in order to perhaps save the planet.
The Governor of Pavonis in Nightbringer.
- Cruel and Unusual Death: Is beaten to death by Prelate Culla. Even Sharben, who notes that she would have died anyway, thought it was a cruel punishment and that she should have died quickly.
- FaceHeel Turn: In Courage and Honour.
- Nice Job Breaking It, Hero!: Her attempts to get the Tau to repair Pavonis only led to the planet becoming a permanent military outpost.

An Adept of the Administratum sent with Ario Barzano.
- Simple Staff: His cane. And it's housing a transmitter.
Kasmir de Valtos
The head of the de Valtos cartel on Pavonis. Was tortured by the Dark Eldar but survived.
- Asshole Victim: He dies, begging for the Nightbringer to make him immortal.
- Didn't Think This Through: His whole plan revolved around freeing the Nightbringer in the belief it would make him immortal as a result. Kasimir realises too late the Nightbringer is as far removed from him as he is from an insect, and the creature doesn't even acknowledge his existence...at first.
- Evil Is Not a Toy: He spends the entire novel working to free the Nightbringer in the belief that it will reward him with immortality, only for it to kill him within moments of being released.
- Fate Worse than Death: Tortured by the Dark Eldar. And he still makes an alliance with them.

An Inquisitor Lord of the Ordo Xenos, who has persecuted the war against the Tyrannids for two hundred and fifty years.
- Absolute Xenophobe: The whole point of his order.
- Well-Intentioned Extremist: As far as he's concerned, nuking a planet and killing its entire population is an acceptable sacrifice to slow the Tyranids down.
A Captain of the Imperial Fists and leader of the Deathwatch kill team on Tarsis Ultra.
- Absolute Xenophobe: It's his job.
The Fabricator-Marshal of Tarsis Ultra.
- Hidden Depths: The Ultramarines, Learchus in particular, dismiss him initially as a preening aristocrat, but he turns out to be extremely skilled at logistics, and manages to get the Imperial forces on his planet fully armed and supplied ahead of the Tyranid invasion.
- Honor Before Reason: Decides to pick up a gun and join the front line after the fighting starts.
A Magos of the Adeptus Mechanicus serving Kryptman on Tarsis Ultra. Later returns to help the Ultramarines fight the Bloodborn.

- Cyborg: Like any tech-priest, he's heavily augmented with cybernetics.
- Electronic Eyes: His right eye is is a cybernetic replacement. It glows red.
- Machine Worship: As a member of the Adeptus Mechanicus, he naturally worships the Omnissiah.

- HeelFace Revolving Door: From Loyalist to Renegade to Chaos Space Marine to Loyalist again.
- Irony: Had to be prevented from killing Grendel for apparently betraying Honsou during the Skull Harvest. Grendel ultimately dies because Vaanes betrays Honsou.
- Honour Before Reason: Notably defies this - he outright tells Uriel that he is no longer a servant of the Emperor, and doesn't care about redeeming his honour.
- I Work Alone: He never felt the brotherhood of the Space Marines.
- Meaningful Appearance: Paints a red cross over his Chapter's symbol, in recognition of his rejection by them ( Also hinting at his Chaos-aligned past with the Red Corsairs). Later, both symbols end up being scraped off to leave the metal bare - Vaanes himself notes it reflects the fact that he no longer has a past, and is motivated solely by survival. Eventually has his Chapter's symbol reappear on his body as a tattoo, reflecting his unwilling return to the Emperor's service.
- Noodle Incident: We never find out what caused his exile - Vaanes himself calls it "a moment's madness" during one of his internal monologues, and never elaborates on what he means.
- Peaceful in Death: Dies looking far more at peace in death than he did in life.
- Wolverine Claws: Most Raven Guard Captains have them.
The Lord of the Unfleshed
The leader of the Unfleshed, once a human boy who was a failed birth of the Daemonculaba on Medrengard.

- Large and in Charge: He is both the largest of the Unfleshed and the leader of their tribe.
- Mercy Kill: Uriel puts the Lord of the Unfleshed out of his misery after the latter is possessed by the dead and used by Sylvanus Thayer to kill dozens of innocent (and not-so-innocent) people.
- Mouth of Sauron: Unwillingly becomes this for Sylvanus Thayer in The Killing Ground.
- My God, What Have I Done?: He is horrified by the terrible things he did while possessed by the dead of Khaturian, and believes the God Emperor will never forgive him for these crimes. Uriel reassures him that the Emperor still loves him before putting him to sleep.
- Was Once a Man: He's a hulking, skinless monstrosity who was once a human child, before the Iron Warriors took him from his home and performed horrible experiments on him in a failed effort to turn him into a Chaos Space Marine.
The Governor of Salinas and former CO of the Achaman Falcatas.
- A Million Is a Statistic: As a quartermaster, he was used to thinking of war in terms of mathematics and statistics with little regard for the human element. This mindset carried over to both his command of the Falcatas and his governorship of Salinas.

- Egopolis: He renamed the capital of Salinas 'Barbadus' after he installed himself as Planetary Governor.
- Governor Evil
- Karmic Death: Is ripped to shreds by the dead of Khartuian.

- Demonic Possession: He inflicts this upon the Unfleshed using the ghosts of Khaturian.
- Expy: A charismatic warrior who was horrifically burned to the point he needs machines to carry out all his bodily functions, and whose natural psychic powers grew stronger because of the trauma? He's basically Gideon Ravenor without his chair.
- Necromancer: His psychic powers allow him to control the ghosts of Barbaden's victims, compelling them to take bloody vengeance on the Achaman Falcatas.
- Not Quite Dead: Survived the final battle with the Falcatas, but was horribly injured.
- Psychic Powers: Developed some after his injuries.
- Psychic-Assisted Suicide: A downplayed example. Thayer used his psychic powers to torment the soldiers who took part in the Khaturian Massacre with visions of the atrocities they committed, driving many of them to kill themselves out of guilt.
- Revenge Before Reason: Anyone who was present at the Killing Ground must die, no matter how many innocents are harmed in the process.
- Traumatic Superpower Awakening: His latent psychic powers only awakened after a combination of Barbaden razing the city of Khaturian (where the families of the Sons of Salinas had been living), and the horrific injuries he received after leading the Sons into a suicidal charge against the Falcatas.
The former commander of the Screaming Eagles company of the Achaman Falcatas, promoted to Colonel of the Salinas PDF after Barbaden became Governor.

A Warsmith of the Iron Warriors, and villain protagonist of McNeill's Iron Warriors series.
- An Axe to Grind: Took one from a dead Black Legion member somewhere between Hydra Cordatus and Dead Sky, Black Sun.
- Arch-Enemy: To Uriel. Honsou hates Uriel for destroying Khalan-Ghol, so he destroys Tarsis Ultra and invades Ultramar to spite him.
- Artificial Limbs: Lost his right arm at Hydra Cordatus. And later replaced his right arm with Pasanius's Necron arm.
- Asskicking Equals Authority: Kills Warsmith Berossus, allowing him command of the latter's Grand Company.
- Bald of Evil: Has close-cropped hair, and is very definitely evil.

- Never Found the Body: The Ultramarines are unable to find Honsou's corpse after he's seemingly buried alive when the tomb of Ventanus collapses on top of him. Sure enough, he's still alive by the end of the series.
- Smug Smiler: And it drives Uriel nuts every time he gives one. Which is probably why he's doing it.
- The Strategist: Responsible for many of the Grand Company's plans throughout the series.
- Taking You with Me: He blows up the tomb of Ventanus while still inside it in a last ditch effort to kill Uriel. They both survive, however.
- Villain Protagonist: Of the Iron Warriors series.
- Visionary Villain: Desires to see the whole of Humanity united under Chaos, as he believes it's the only way for them to survive in a galaxy of threats. Also has some kind of plan that requires him to speak with Perturabo himself, as The Corpse Road implies.

- Commander Contrarian: Continually argues with Honsou, and loves reminding Honsou of his failures and mistakes.
- Death Ray: Uses a meltagun.
- Delinquent Hair: Has a mohawk.
- The Dragon: Ironically, in any other situation, he would be The Brute.
- Facial Horror: Suffers this during the battle for the Indomitable after taking a shot from an Inferno Pistol to the face. He explicitly states he can feel his flesh "running like molten pitch" when it hits.
- Fake Defector: Infiltrates Pashtoq Uluvent's warband on Honsou's orders, then betrays him at the last minute.
- Good Scars, Evil Scars: Has a lot of scars, particularly on his face.
- I Fight for the Strongest Side: He initially serves under Berossus and fights against Honsou, only to switch sides after Honsou kills his boss.
- Irony: He tells Pashtoq Uluvent that he's siding with Honsou because he thinks he can live through the fight Honsou will lead him to. He's wrong.
- Neck Snap: On the receiving end of one from Adaric Vaanes.
- Suspiciously Similar Substitute: As a Khornate Iron Warrior who butts heads with Honsou at every opportunity, he comes across as a more stable version of Kroeger from Storm of Iron.
- Weapon of Choice: He likes the chainsword, but he loves his meltagun.
- Your Head Asplode: Vaanes punches Grendel in the head with enough force to snap his neck and shatter his skull, killing him instantly.
A possessed Chaos Space Marine among the Iron Warriors.

- The Dragon: To Honsou, serving as his bodyguard.
- Glowing Eyes of Doom: His eyes and veins are constantly glowing silver.
- Hero Killer: Rips through Adaric Vaanes' warband, outright killing well over a dozen Space Marines in moments, and almost kills Uriel, stopping only because Honsou wants him alive.
- I Know Your True Name: Freely gives it to Honsou as a sign of fealty. Probably because Honsou couldn't pronounce it.
- Lightning Bruiser: Quick enough to outmanoeuvre Space Marines, and more than capable of tearing their spines out.
- Transformation of the Possessed: Can take on a more overtly Daemonic form when he lets the Daemon possessing him take over.His claws swelled to become monstrous golden swords... his face swelled and rippled, black horns curling from his temples and gleaming lines of augmentic body parts becoming visible as the Daemonic entity took complete control of his body.
A Warsmith of the Iron Warriors, who engages in a war with Honsou for refusing to share gene-seed from Hydra Cordatus.

- Badass Cape: It's stronger than Adamantium!

- Exotic Eye Designs: Both eyes are entirely gold-coloured, without iris or pupil.
- Gorn: Refuses to clean the blood off his gauntlets as a sign of his ability. He's been alive since the Horus Heresy. That's a lot of blood.
- Non-Action Big Bad: Which is how Honsou convinces Berossus's men to join him.
- Red Oni, Blue Oni: The blue to Berossus's red.
- Uncertain Doom: Attacks Khalan-Ghol at the head of his top warriors, only for them to be attacked by the rampaging Heart of Blood. It's never explicitly confirmed as to whether he died or escaped back to his citadel, but Honsou certainly thinks him dead.
- White Hair, Black Heart: Has white hair, and is quite evil.
A Chaos Dreadnought and vassal Warsmith of the Iron Warriors, who engages in a war with Honsou for refusing to share gene-seed from Hydra Cordatus.
- Ace Custom: His Dreadnought shell is notably bigger than standard, and possesses a lot more weapons than normal.
- Bearer of Bad News: In the Horus Heresy novella The Crimson Fist, he served as adjutant to Perturabo, and later had to tell Perturabo that Sigismund was not in command of the Imperial Fists Retribution Fleet, but Alexis Pollux. Perterabo responded by hitting Berossus twice, which is heavily implied to be what put him in the Dreadnought.
- The Berserker: Throws his warriors against Honsou's walls, has all captives disembowelled to taunt the defenders, displays incredible glee while murdering everything in sight - yep, he's one.
- Bullying a Dragon: Spends the majority of his face-to-face meeting with Honsou insulting him, while having a large amount of Iron Warriors aiming weapons at him.
- Cruel and Unusual Death: Gets torn apart by Honsou and Onyx, solidified when Honsou rips Berossus's skull and spine out and shatters them.
- Drop the Hammer: One arm is a piston-driven siege hammer.

- This Is a Drill: One of his main arms is a siege drill.
- Man in the Machine: Entombed in a Dreadnought, sometime during the Horus Heresy.

- Be Careful What You Wish For: Wanted a confrontation with the Heart of Blood. Gets killed and devoured by it, after it powers up via Bloodstorm.

Heart of Blood
A Bloodthirster of Khorne, imprisoned in Khalan-Ghol to make the fortress unconquerable.
- An Axe to Grind
- Berserk Button: Sorcery, and Psykers in general.
- Big Red Devil: Like most Bloodthirsters, it's a giant, red-skinned daemon with horns and bat-like wings.
- Bloody Murder: The Bloodstorm.
- The Juggernaut: Near completely unstoppable, especially when angry. Toramino's army found that out the hard way.
- The Rival: With The Omphalos Daemonium.
- Sealed Evil in a Can: Sealed in Khalan-Ghol by the Warsmith to prevent sorcery from breaching the walls.
- Whip It Good: Wields one of these, as well as An Axe to Grind.
A daemon prince imprisoned by Marneus Calgar sixty years ago.
- Arch-Enemy: Of the Ultramarines in general and Marneus Calgar in particular.
- Bad Boss: It kills an underling and devours their soul simply for approaching Mkar without observing the proper rituals.
- Big Bad Duumvirate: With Honsou in The Chapter's Due, and neither is happy about it.
- Butt-Monkey: For the longest time, it was something of a running gag within the fluff that M'kar was easily defeatable. The Chapter's Due and Codex: Grey Knights helped fix that perception.
- Deader Than Dead: Mkar dies a true death from Uriel saying its true name and Marneus Calgar stabbing it with the shard of Erebus.
- Demon Lords And Arch Devils: It's a Daemon Prince of Chaos Undivided, and brings forth legions of daemons to besiege Ultramar. The text even refers to M'kar as "the daemon lord" at several points.
- Demonic Possession: After being freed from the Indomitables warp core, Mkar possesses the Ultramarine Dreadnought Brother Altarion to gain a physical form. Altarions tortured soul still exists within Mkar, powerless to fight back.
- The Fundamentalist: Not that surprising. He was a Dark Apostle of the Word Bearers.
- I Have Many Names: As Moriana the Chaos Witch claims, M'kar changes his names every few centuries to protect his true name.
- I Know Your True Name: "I name thee Maloq Kartho."
- It's Personal: Hates the Ultramarines (and Calgar in particular)for imprisoning him in a Warp Core - The fact he was a Word Bearer, and thus potentially witnessed Monarchia, also plays a part.
- Red Baron: The Thrice Born, the Reborn, Father of the Blue Sun.
- Sealed Evil in a Can: Marneus Calgar imprisoned MKar in the star fort Indomitables warp core sixty years before the events of the novels. Honsou frees him shortly before The Chapters Due.
- Time Abyss: He's been alive since the Horus Heresy.
- Timey-Wimey Ball: Thanks to the Warp he did stuff while imprisoned, including sending the Grey Knight Supreme Grand Master into the Warp.
An Iron Warrior who was made from the genetic material of Uriel Ventris. Even people who semi-willingly work for Honsou are creeped out by it.
- Body Horror: Its skin is made from flayed slave skins, stitched onto its muscles - and this was after its original skin was removed from him by the Daemonculaba.
- Cloning Blues: It is not grateful for Ventris's gene-seed.
- Death Seeker: Actually thanks Ventris for killing it.
- Facial Horror: This official art of it should say an awful lot.◊ It later tears off its face before fighting Uriel.
- Genuine Human Hide: Has the skin of dead slaves stitched onto its muscles, due to the Daemonculaba process.
- Healing Factor: The Newborn can regenerate from horrendous injuries. Pasanius blows its chest open at one point, only for it to regrow the destroyed bones, organs, and muscles. Its Healing Factor fails when Uriel stabs it with the shard of Erebus, however.
- Impaled with Extreme Prejudice: Dies this way.
- I Know Your True Name: "Samuquan!" But instead of freeing him, it drives it over the edge.
- It Is Dehumanising: Consistently referred to with "it" pronouns.
- Tortured Monster: Being the Newborn would not be a fun existence. Sure, you get incredible power and a Healing Factor, but you live in a constant state of torturous pain and incipient madness. It's small wonder it lashes out at whatever Honsou directs it towards.Grateful? My life is fragments. I am the broken shards of two people and I live in pain with every moment that passes. Grateful? No, Ventris cursed me to the agony of a life I didn't ask for. He made me what I am and there is not enough pain in the world for what he will suffer in return.
- Was Once a Man: It was a normal boy until the Iron Warriors kidnapped him and shoved him inside a Daemonculaba, transforming him into a monster.
A former Magos of the Adeptus Mechanicus who turned to Chaos.
- Body Horror: The Obliterator Virus infected him, so this is a given.
- The Cracker: His speciality; he sits in command vehicles behind the lines and launches Scrapcode attacks from afar.
- The Evil Genius: See above.
- FaceHeel Turn: Was an Adeptus Mechanicus Adept, turned to Chaos' side after being infected with a modified version of the Obliterator Virus.
- Impaled with Extreme Prejudice: How he meets his end, shortly before the Black Basilica blows up.
- Was Once a Man: Now a blob like man...thing.
A member of the Dark Mechanicum who has been bonded to a fragmentary artificial intelligence and connected to his war machines.
- Demonic Possession: Specialises in Daemon Engines.
- General Failure: He's a piss poor general, but what he lacks in strategy, he can make up for in sheer numbers.
- Man in the Machine: By the time of the attack on the Indomitable, he's little more than a bunch of ruined flesh swirling in amniotic suspension while connected to his spider-like war machine.
- Mad Scientist: As a member of the Dark Mechanicus, this is a given.
- Tank Goodness: He can turn anything into a tank.
- The Unintelligible: The only time he speaks, it comes out as a frothing mess of scrapcode.
The Master of the Blade Dancers, a group of swordsmen devoted to Slaanesh.
- Combat Pragmatist: Very occasionally. The astonishingly callous manoeuvre he comes up with on the Indomitable namely sending a ship on a suicide mission so that it crash-lands on the Imperial defensive lines and devastates them even impresses Honsou.
- Combat Sadomasochist: Actually thanks Honsou for driving shards of bone into his lungs at the Skull Harvest, because apparently the pain was...exquisite.
- The Hedonist: Slaaneshi. That says it all.
- Double Entendre: Cracks a BDSM joke at the climax of the Skull Harvest.
- Go Out with a Smile: Dies screaming 'Incredible!' and convulsing in pleasure as an Eversor's poisons kill him.
- Honor Before Reason: Expects the etiquette of a duel to be obeyed, even when facing an Eversor Assassin. This eventually gets him killed, when an Eversor kicks him in the head then poisons him.
- Master Swordsman: Able to go toe-to-toe with an Eversor Assassin. For a time, at least.
- Sense Freak: He's addicted to sensation, but what do you expect with a follower of Slaanesh?
Etassy's successor as The Mistress of the Blade Dancers.
- The Brute: If it weren't for Kaarja Salombar, she'd be the Dark Chick.
- Dodge the Bullet: The Ultramarines and Raven Guard fire three volleys of bolt rounds at Xiomagra and her Blade Dancers. Thanks to her incredible reflexes, not a single round touches her.
- Dual Wielding: She wields a pair of swords.
- Master Swordsman: She completely outclasses Uriel in swordplay, inflicting dozens of wounds upon him without taking any in return. When Uriel tries to go for her heart, she disarms him effortlessly, and would have taken his head off if not for Petronius Neros timely intervention.
- Scary Black Woman
- Slashed Throat: Her brief but intense duel with fellow Master Swordsman Petronius Nero ends with him slitting her throat.
Leader of a group of Corsairs. Joined Honsou's army after he won the Skull Harvest.
- Defiant to the End: She uses the last of her strength to spit at Cato Sicariuss feet before he decapitates her.

- Space Pirate
- You Gotta Have Blue Hair: She has a mane of azure hair.
