ah! truely the single most important event of any day - feeding time!

i figured this was just the start, but as i'm really into the cursed founding stuff i posted it!
the 1st chapter approved book, (1999 or 2000 i think?!) has the list from the earlier white dwarf that had the huge list of 'offically named' gw chapters... plus there's the 100 or so chapters listed in 'how to paint space marines'!

though, i guess we can't go too overboard on the smurfs?!

cheers!

Yes indeed. There's also Mortifacotrs, Relictors, Doom Eagles, Silver Skulls, Sons of Medusa, Howling Griffons, White Panthers, and the Blood Ravens. Some of those are from the 3rd edition codex in the painting section, so I don't know if they count as "official"...

There's also the 13th Dark Founding Chapters, but the only one I know of was the Exorcists.

[Dan296]

lamenters are an official blood angels succsessor. another one thats not included is the angels sanguine
its not emporers scythes, its scythes of the emporer. they also werent wiped out, but almost. little details, but still.

[Cagarner]

Icarus, I think you should update the list.

i've got some background for the lamenters based on the few hints that have been droped about their polluted gene-seed...
the rummor goes that the techpriests, looking to have some fun 'experimenting', combined the blood angel and dark angel gene-seeds in order to breed out the deficiancies known to mare both those otherwise superior gene-seeds!
too bad about the 'side effects' though! (damn techpriests just having to tinker with everything!!!)

and also, both "emperor's scythes" and/or "scythes of the Emperor" are accepted and commenly used names for the chapter... their are rummored to be about 1 company of battle-brothers left after the chapter's near defeat by hive fleet kraken. most are believed to be serving within the deathwatch.

cheers!

ah! the rainbow warriors... they had a little 'encounter' with the sisters of battle...
seeing as the sisters are still around, it's believed that the chapter was wiped out for some unkown reason! (although their cuddly name might have had something to do with it?!!)

cheers!

[Stubber]

Found a massive list of every chapter mentioned by GW. I'll put down as many as possible and chances are there'll be a few already mentioned.

A

Angels Encarmine
A Second Founding chapter of the Blood Angels. They participated in the effort to reclaim the Crimson Fists' homeworld from the Orks. Their power armour is painted red, with black trim and a black backpack. The Chapter symbol is a bat-winged drop of blood.

Angels Porphyr
The Angels Porphyr Chapter was founded in the 31st millennium. Their power armour is halved blue and white (with pad trims matching the pad). The Chapter symbol is the profile of a winged skull, and other skull icons are often incorporated into their armour. The Chapter participated in the Third War for Armageddon.
The Chapter appears almost identical to the 'Eagle Warriors' chapter, the only differences being the chapter badge (Eagle Warriors simply have a blue wing). This leads many to believe the Angels Porphyr and Eagle Warriors to be the same chapter.
According to Insigneum Astartes the Eagle Warriors denote company by the colour of the left kneepad, it would seem the Angels Porphyr denote company by the colour of the right kneepad.

Angels Sanguine
A Second Founding chapter of the Blood Angels. Their power armour is halved red and black. The Chapter's symbol is a winged skull. Librarian Ashok is a member of the Angels Sanguine chapter, and he wears the Shroud of Lemartes, to stave off the Red Thirst. He also is unique in the aspect that he is one of the few Space Marines to dislike his armor, and senses that its machine spirit is not fond of him either.

Angels Vermillion
A Second Founding chapter of the Blood Angels. The Chapter wears dark red power armour. The Chapter's symbol is a winged blood drop, with a small skull at the base of the drop.
Angels of Absolution
A Second Founding chapter of the Dark Angels. The power armour of the Angels of Absolution is painted bone-white, and the Chapter's symbol is a skull superimposed over a stylised wing.
Angels of Fire
A chapter founded during the 36th millennium. The Angels of Fire wear red power armour, decorated with stylised orange flames. They participated in the Third War for Armageddon.

Angels of Redemption
A Second Founding chapter of the Dark Angels. The Chapter's power armour is halved bone-white and dark green, and the Chapter's symbol is a winged skull.

Angels of Vengeance
A Second Founding chapter of the Dark Angels. The power armour worn by this chapter is black, and the Chapter's symbol is a white winged skull. An inverted red V rests over the skull (a hood).
Angels of Vigilance
The Angels of Vigilance wear yellow power armour (including trims) with a black chest eagle. The Chapter's symbol is a winged, flame-filled crucible.
It is suspected that the Chapter came into existence during the Second Founding, but it is unknown from which Legion their gene-seed originates.

Astral Claws
The Astral Claws were created during the 35th millennium to guard against the numerous threats emerging from the Maelstrom. The Chapter was led into Chaos by their traitorous Chapter Master Lufgt Huron (thereafter known as Huron Blackheart), igniting the Badab War. They currently form a group of rebel Marines known as the Red Corsairs, who ruthlessly attack supply lines in the name of Chaos. In the battle that pulled them into Chaos they nearly succeeded in pulling the Mantis Warriors with them. Since turning to Chaos, the rebel Chapter is known for having Marines that have felt the lure of Chaos from other chapters, such as the Crimson Fists, Dark Angels, etc, join them, either individually, or by squad.

Avenging Sons
A 19th Founding chapter from the world of Trækonnis Major. They wear navy blue power armour, and their symbol is a stylised white cross. A white diagonal stripe with a Roman numeral in the centre denotes the company. A strike force of Avenging Sons fought in the war on Taros.

B

Black Consuls
A Second Founding chapter of the Ultramarines. The Chapter's powered armour is black with trim in the company colour. The symbol of the Black Consuls is a white eagle's head.

Black Dragons
The Black Dragons were one of the Space Marine Chapters created during the Cursed 21st Founding. They are censured by the Inquisition due to mutation of the Chapter's gene-seed, which causes certain marines to develop blade-like outgrowths of bone on the head and forearms. Black Dragons afflicted in this way, sharpen these bone growths and sheath them in adamantium for use in close combat. They are then grouped together into specialist jump-pack equipped assault squads know as Dragon Claws.
The Black Dragons suffered heavily during the Third War for Armageddon and suspect Inquisition meddling, although this cannot be proven. Their losses have been so grievous that the Chapter itself is in danger of extinction. Nevertheless, the Chapter remains loyal to the Imperium, and is prepared to fight to the last man no matter the forces arrayed against them.
The Black Dragons wear black power armour, with white chest eagle and shoulder guard markings. Their chapter symbol is a white dragon on a black background, and dragons are often incorporated into their armour and weapons.

Black Guard
A Second Founding chapter of the Raven Guard.

Blood Drinkers
A Second Founding chapter of the Blood Angels. Unlike the other Blood Angels Successor Chapters, the Blood Drinkers are strict followers of the Codex Astartes. The Chapter participated in the effort to reclaim the Crimson Fists' homeworld from the Orks. The Chapter's armour is painted red, with yellow trim. The Chapter's symbol is a drop of blood above a grail.
The name "Blood Drinkers" comes from the Chapter's craving for blood, the result of a mutated omophagea gene-seed.

Brazen Claws
A Second Founding chapter of the Iron Hands. They participated in the defence against the Thirteenth Black Crusade. The Chapter's powered armour is painted in a quartered blue and red pattern. The Chapter's symbol is the depiction of red claws or talons.

Brotherhood of a Thousand
A later-founding chapter of unknown origin. The Brotherhood follow the Codex Astartes and are loyal to the Imperium of Man. Their armour is painted a bluish grey with the trim on the shoulder pads painted a different colour for each company. Their chapter symbol is a black "M" on a slightly undersized white circle, the M representing the number one thousand.

C

Celebrants
A Chapter founded during the 36th millennium. They participated in the Third War for Armageddon. Their armour starts with yellow lower legs then seamlessly blends to orange for the mid body and then red for the upper body/helmet/arms; the chapter badge is a winged five-pointed star.

Celestial Lions
The Celestial Lions were founded during the 38th millennium. Their armour is primarily gold, with blue shoulderpads and helmet. The chapter symbol is a roaring lion, and lion decorations are often incorporated into their armour. The Celestial Lions participated in the Third War for Armageddon, and were almost completely annihilated due to Inquistion treachery.

Children of Purgatos
A chapter that went excommunitcate, their primary color is emerald green highlighted with gold and they decorate their armor with images of flames. Chapter badge is currently unknown.

D

Damned Company of Lord Caustos
A group of Space Marines that turned to the Chaos gods after they were declared traitor by an Inquisitor of the Ordo Hereticus, based on some flimsy and circumstantial evidence. They only turned to chaos to survive in a galaxy hostile to them, they now live their lives as mercenaries.
Their armour is primarily grey/purple, with gold decoration. Their chapter's symbol is yet to be seen.

Dark Hands
A chapter that fought the Hrud at Chinchare. The Chapter's armour is painted dull green, and the Chapter symbol is of an outstretched black hand facing the viewer as if in a halt gesture. The gloves are also painted black. It is possible the Dark Hands are an Imperial Fists successor but that is merely speculation.

Death Spectres
The Death Spectres are a chapter of Space Marines that participated in the defence of the Cadian sector against the 13th Black Crusade. During the Black Crusade, the Death Spectres adopted a fluid style of combat, using jump pack equipped troops to quickly capitalise on any gains made by the Imperial Guard.
Their armour is black (including trim), with the exception of the left shoulderpad (white with black trim) and helmet and chest eagle (both bone). The chapter badge is a pair of black scythes located behind a skull.
All members of the Death Spectres are albinos.

Death Strike
Wearing light blue armour with a yellow winged lightning bolt as a chapter badge, the Death Strike Chapter participated in the Assault on Moros and acted as the rearguard during the Verdan II Extraction.

Destroyers
A Second Founding chapter of the White Scars. Their armour is acid yellow with a red chevron pattern down the arms. Their symbol is two crossed lightning bolts.

Doom Eagles
A peculiar, non-Codex Chapter, whose initiates are selected from the aspirants who survive particularly harrowing trials. At a basic level, all Doom Eagles accept that they are already dead. This is the root of their courage, their unshakeable determination to face the greatest odds. As such the men of this Chapter are almost impossible to deter, but they are dour, grim and depressive, albeit staunchly loyal to the Imperium.
Doom Eagles armour is primarily silver, with red decoration. The chapter's symbol is a stylised eagle, with a human skull replacing the eagle's head.

[Stubber]

E

Eagle Warriors
This Chapter has a white uniform with blue detailing, with a blue wing as its badge. They participated in the Balur Secundus Strike Force.

Emperor's Hawks
This Chapter has red armour, with a yellow trim on the shoulder pads. Their chapter symbol is a single wing. The Hawks specialise in jump pack-assisted assults, followed by squadron-strength units of Landspeeders.

Emperor's Warbringers
This Chapter has a grey-green uniform, with crossed swords as its badge. They are not averse to using camouflage on their vehicles.

Excoriators
One of the chapters founded to make up the Astartes Praeses, twenty chapters assigned to guard the regions surrounding the Eye of Terror. Their chapter is a stout Codex one. Their armour is white with silver gauntlets and trim, and their symbol is a flaming, double-headed axe.

Executioners
One of four chapters that rebelled during the Badab Uprising. The Chapter was believed to have found itself on the wrong side through little fault of its own, and was permitted to continue in its service to the Imperium. The Chapter's power armour is painted in a blue and grey camouflage pattern, with the exception of a single shoulderpad which is painted green for tactical squads, yellow for assault squads, purple/blue for devastator squads or red for recon squads. The symbol of the Executioners is an axe on a red background.

Exorcists
The Exorcists were founded in M36 some time before the Age of Apostasy. They were created through secret Inquisition experiments in which test subjects were deliberately allowed to be possessed by daemons for a time before the daemons were banished by daemon hunters. There were casualties, but the majority of test subjects survived and were versed in the ways of combating daemonkind. The test subjects, two companies strong (200 Space Marines) were released onto a daemon-infested planet where they displayed extremely impressive results. They have since been sanctioned as an official Chapter and are often involved in operations overseen by the Ordo Malleus of the Inquisition. They wear red power armour with black trim. The chapter's symbol is a horned skull. The Exorcists participated in the Badab War, the Gothic War, the Third War for Armageddon and in the defence against the Thirteenth Black Crusade.

Extinction Angels
One of the chapters that turned to chaos after the Horus Heresy, the chapter is famous for its assault skill. During the 13th Black Crusade the chapter fought alongside the Black Legion on the planet Demios Primary, where they scattered the Skitarii forces who were protecting the many forges of the Adeptus Mechanicus. The planet was liberated by the Black Templar space marines and it is believed that the Angels are still hidden in the lower depths.
Their armour is a dark purple with gold details and their symbol is a skull wearing a red hood, behind a grey Scythe.

F

Fire Angels
This chapter wears white with red trim, and displays a red cross bottony as their symbol. They fought in the Badab War and in the Battle of Sagan's Moon.

Fire Hawks
One of the chapters created during the Cursed 21st Founding, from Ultramarines gene-seed. The Fire Hawks disappeared into the Warp during the 41st millennium, and were declared Lost in the Warp.
Shortly after this, ghost Space Marines began to appear on various battlefields. These apparitions came to be known as the Legion of the Damned, 'fading' into existence to support beleaguered Imperial forces, and fading out again as soon as the battle was won. This has caused some to suspect that the Legion of the Damned and the Fire Hawks are one and the same.
The armour of the Fire Hawks is predominantly yellow, with red flame decorations. The Chapter's symbol is a mushroom cloud. The Legion of the Damned armor is black as midnight and marked with symbols of death and damnation; skulls grin cheerlessly from helm and boltgun, bones twist amid the flames of purgatory.
The Fire Hawks participated in the Badab War and in the Assault on Terra at the end of Goge Vandire's Reign of Blood.

Flame Falcons
One of the cursed Space Marine chapters created during the Cursed 21st Founding. Although their earlier successes promised a great future for the chapter, they were almost wiped out by the Inquisition before a hundred years had passed.
The cause of the Inquisition's attack was the fact that during an engagement, members of the Chapter burst into flame. These Marines came to no harm, and believing the flames to be a gift from the Emperor, fought with a fierce savagery that won the day.
The members of the Inquisition did not share this belief, and when the Chapter returned to their homeworld of Lethe to celebrate, they were attacked and almost destroyed by a force of Grey Knights.

Flesh Eaters
In very old literature, this chapter painted their helmets with snarling maws and sharp, blood-dripping fangs. They were loyalists. They have not been mentioned in literature over the last ten years at least, possibly because their fearsome appearance could confuse gamers who would naturally assume the Flesh Eater marines to be Chaos corrupted.
The Flesh Eaters are a Third Founding successor chapter of the Blood Angels. According to the literature, the taint indicative of a Blood Angel successor chapter has manifested itself in a dependency on the blood of others. If not given fresh blood or raw meat, the Space Marines eventually either wither away until they finally die as shrivelled husks, or they succumb to the Black Rage. The Flesh Eaters are strongly distrusted by most forces of the Imperium, with some Imperial Guard regiments and Space Marine chapters refusing to fight alongside them due to their ruthlessness and brutality, their disregard for human life, and the constant rumours of cannibalistic rites. There are also persisting rumours that the chapter suffered from an internal conflict arising from heresy and treachery where an untold number of the chapter succumbed to Chaos, although the truth of this cannot be ascertained, for the secrecy and seclusion of the Flesh Eaters have made any investigations futile.
It is stated in earlier literature that the Space Marines are famous for their blood-drinking and flesh eating rituals. Rather than being an aberrant chapter, the Flesh Eaters would simply possess a common Space Marine trait. This trait comes from the Omophagea implant received during a new recruit's stages of organ implantation. With this implant the Marine can absorb some of the memories of a creature by eating its flesh. This ability has given names to chapters such as the Blood Drinkers, Flesh Tearers, etc.
The chapter's armour was dark red, with white iconography and decoration. This was changed at some point in the chapter's history to black armour with red lower legs. The symbol of the Flesh Eaters is a stylised monstrous jaw.

Flesh Tearers
A Second Founding chapter of the Blood Angels, they are afflicted by a dangerous gene-seed alteration which causes most veterans to succumb to the effects of Black Rage. They are affected by it more than any other chapter, and therefore have dwindling numbers. They favor assault tactics, and they are infamous for their savage style of fighting and rumors of cannibalism and blood-drinking rituals. The Flesh Tearers participated in the Third War for Armageddon where the chapter was nearly declared Excommunicate and subjected to Inquisitorial investigation after they had, in a fit of the Black Rage, slaughtered civilians once they had run out of Orks to kill. Amongst the Orks of Armageddon the chapter became known as the 'Eaters of the Dead'. Later in the campaign, Orks were known to have retreated when Flesh Tearers attacked, a display virtually unheard of.
Notable members include: Chapter Master Seth - Guardian of the Rage and High Chaplain Carnarvon - Watcher of the Lost.
The chapter's colour scheme is primarily red, with black shoulderpads, helmet and backpack. The chapter's symbol is a drop of blood on a white design similar to a circular saw blade.

G

Genesis Chapter
A Second Founding chapter of the Ultramarines. The chapter's power armour is red with yellow details; their symbol is an upside-down "V" on top of a white triangle.

Grey Slayers
Inquisitor Thrax purged them of mutants and daemons, and the Chapter Master took his own life. Untainted officers were raised up to lead the chapter. The Grey Slayers' eventual disposition is unknown.

Grief Bringers
A chapter that suffered heavy losses fighting against enslavers on Valhall II. Their armour is described as "Principally a sickly pea-green, with engrailed chevrons of headachey purple"

H

Harbingers
The Harbingers hail from the Black Planet and are widely respected for their skill at planetary assaults and ship-to-ship fighting. They consider themselves sworn enemies of the Death Guard Traitor Legion, and as soon as word reached them of the 13th Black Crusade, they redirected their forces away from the Orks of the Piscinan Belt towards this new threat.
They are currently led by Nimrod Grudge, and sent eight companies to combat the threat of the 13th Black Crusade. Their chapter colours are white with a yellow helmet and their chapter symbol is falling star, with the star replaced by a skull.

Hawk Lords
A Codex chapter whose armour is coloured purple with gold trim and chest eagle. The chapter symbol is of a hawk depicted in a similar style to the German Eagle. The colour of this chapter is very similar to that of the pre-heresy Emperor's Children.

Heralds of Ultramar
A Codex chapter derived from the Ultramarines. Their appearance is identical to Ultramarines, except for the use of a winged, five-pointed star as the chapter's symbol,and a white trim on their shoulder pads and chest eagle.

[Stubber]

I

Immortal Hearts
One company present after the first Season of Fire during the Third War for Armageddon.

Inceptors
A Second Founding chapter of the Ultramarines.

Iron Champions
The Iron Champions were one of the chapters that participated in the 3rd Armageddon War; they dispatched seven companies. During the war, the chapter launched a massive drop-pod assault to support the Celestial Lions and were it not for the two chapters, Hive Volcanus would have remained in Ork hands.
The chapter's power armour is painted black with the helmet and shoulder pads painted grey. The chest eagle is red and the face of the helmet often has a gold skull painted on it. The chapter's symbol is a skull in the middle of an Iron Halo.

Iron Fists
They are said to "bear shields moulded into the shape of a medieval armoured gauntlet." Their power armour is painted a light blue-grey with gold arms. Their symbol is a gold gauntlet in the shape of a fist upon a field of light blue-grey.

Iron Hearts
Briefly mentioned in the short story "Hell in a Bottle" by Simon Jowett published in a Book entitled "Into the Maelstrom". Their Primarch is mentioned as "Primarch Rubineck", possibly one of the unknown primarchs listed in the space marine codex. The removal of this chapters name may be resultant of the content of the short story where at the end a chaos lord gains entrance to the fortress monastery via the body of a failed space marine.

Iron Knights
A chapter of Space Marines who were on a self-imposed penitence crusade when they were called into action during the 13th Black Crusade. They are described as having "gleaming, blue-grey armour".
The chapter's marines curiously bear their squad marking on both shoulderpads, with the chapter badge relegated to a small shield located in the front corner of their left shoulerpad.
The Iron Knights are a smaller chapter and are primarily a strike force style chapter which focus on attacking with terminators and other heavily armoured units and vehicles.

Iron Snakes
One of the many chapters of Space Marines who participated in the defence against the Thirteenth Black Crusade. The chapter also contributed Marines towards the Sabbat Worlds Crusade. Amongst the battles fought in that Crusade were: the relief of the Guard on Ambold Eleven and the assault on Pelbury Civitas, the cleansing of the daemon-infested Fornax Aleph, the support of the final extermination of the Zoican horde on Verghast and, of course, the destruction of the mechanised mutant army of Presarius.
Their power armour is silver, and the Chapter's symbol is a blue snake on a white background.

L

Lamenters
One of the chapters created during the Cursed 21st Founding. The Lamenters are believed to have been created from Blood Angels gene-seed, modified to remove the effects of the Black Rage and Red Thirst. This appeared to have been in some way successful. However, the Lamenters are noted for suffering from a kind of melancholy, although it is unclear if this is due to some uncalculated flaw in their geneseed or if it is simply a result of the unfortunate events that have repeatedly befallen the Chapter.
The Lamenters are considered an unfortunate, or even cursed chapter. During the early centuries of the 41st millennium, they became involved on the wrong side of the Badab Uprising. Investigation after the event showed that the Lamenters had not rebelled out of treachery, but of pride. They saw the attacks by the Imperium on the Astral Claws as infringing upon the autonomy of the Adeptus Astartes. They were eventually granted forgiveness for their actions and sent on a one hundred year crusade of penance.
Unfortunately, their bad luck seemed to follow them, as this crusade led them straight into the path of the Tyranid Hive Fleet Kraken. Although they were instrumental in slowing the advance of the alien menance, the Lamenters took devastating losses as a result. In one particularly notable battle, a number of Lamenters Space Marines fought a heroic last stand on the planet Malvolion which was being rapidly consumed by Tyranid organisms. The actions of the Lamenters allowed for many Imperial civilians to escape the doomed world, but they lost their lives in the process. As a result of the horrific losses they suffered in their many battles with the Tyranids, barely 3 companies of the Lamenters still remain.
The power armour of the Lamenters was originally yellow except for a red helmet stripe and the right shoulder pad which was decorated with white and black checks, upon which rested the Chapter's symbol: a bleeding heart.
The above scheme referred to MkVI Corvus pattern Power Armour. The recent How To Paint Space Marines book includes a MkVII Eagle pattern Power Armour scheme that darkens the armour to a mustard yellow, and (following standard MkVI to MkVII conversion rules) transfers the chapter badge (and the checked pattern) to the left shoulderpad and drops the helmet stripe completely.

Libators
A Second Founding chapter of the Ultramarines. Their armour is blue with a maroon checked pattern on the leg armour; their emblem is two crossed black pickaxes on a red field. The colour changes to designate the company. Their one peculiarity is that their basic weapon is the storm bolter.

[Stubber]

M

Mantis Legion
Sometimes referred to as the Mantis Warriors, the Mantis Legion was one of the three chapters that joined the Astral Claws in rebelling during the Badab Uprising. However they later rejoined the Imperial forces and joined the attack on Huron Blackheart and the Astral Claws.
Since then they have been treated with suspicion and are under constant scrutiny. Before they rebelled they had an above average induction rate for the Deathwatch, but since rebelling only a handful have been accepted. They are no longer banned from recruiting by the Inquisition, although the chapter size is still dangerously low. The chapter was birthed from the Mordriana System, near the Eye of Terror, though they have had their right to a homeworld revoked and so currently reside in their space fleet.
A current Games Workshop release indicates the Mantis Legion's use of a unique unit known as a 'Tranquility Sniper Squad'. How this relates to their background, if at all, is still unknown. The only other non-Codex troops mentioned are the elite 'praying mantidae'. This elite cadre are selected from the most driven and pious members of the chapter and live for the sole purpose of hunting the Red Corsairs in order to bring honour back to the chapter. They are recognisable by snake-like tattoos covering their body, extending high up their necks.
Though a successor chapter, Mantis Warrior gene-seed is unusual and is rumoured to allow the Mantis Warriors to enter a haze-like state in which the warrior's perception of space and time are slowed down, allowing him to react and fight at an accelerated speed. This battle haze is a permanent state and the marine is caught in it until he dies. Their melee combat is also helped by the notched adamantine blades attached to the lower arm armour.
The chapter colour scheme was orignaly green with their symbol being a flying insect, but has changed to shining green with gold edging. The chapter symbol is a flaming mantis claw. All marines in this chapter appear to have green eyes and long black hair.
A few members who have "unofficially" joined the Deathwatch through death in battle: Librarian Shaidan, Sergeant Ruinus (Devastator Squad), and Sergeant Soron (Assault Squad)

Marauders
A Second Founding chapter of the White Scars. Marauders' power armour is yellow.

Marines Errant
Their chapter colours are a bisected blue and white scheme, with a shooting star, graduating from red to yellow, as their symbol. They participated in the Second Outer Galactic Expeditionary Force and the Badab Uprising.

Marines Exemplar
The Marines Exemplar dedicated all but one reserve company to the efforts against the 13th Black Crusade of Chaos. They were one of the chapters founded to make up the Astartes Praeses, twenty chapters created to guard the regions surrounding the Eye of Terror.
Their power armour is black with red arms and shoulderpads (including trim); their chapter badge is a black skull with spikes radiating from the top.

Marines Malevolent
The Marines Malevolent Chapter was founded in the 32nd millennium. Their power armour is yellow (including trim) with the exception of the torso and backpack which are black. Their chapter symbol is a black winged thunderbolt.
During the Third War for Armageddon, the Marines Malevolent were censured for launching attacks that cost the lives of hundreds of innocent civilians. Apparently this chapter believes that the end justifies the means and are therefore prepared to conduct war as they see fit regardless of who is hurt in the crossfire. Captain Vineyard of the Marines Malevolent and Master Tu'Shan of the Salamanders were involved in a tense altercation in the aftermath of this incident. Some sources imply that one participant went so far as to strike the other - a severe gesture in the ethos of the Adeptus Astartes - but this is unconfirmed.

Mentors
Often referred to as the Mentor Legion. They are the second chapter to be designated number 888 (the first one being the Star Scorpions). The Mentors' armour is painted dark green over the body and helmet, with white arms, shoulders and legs. The chapter's badge was originally the stylised face of an owl, but was later changed to a plain red falcon's head, seen in profile. The Chapter-Master of the Mentors, named Nisk Ran-Thawl, has visited Earth, and is rumoured to have been granted an audience with the God-Emperor.
The chapter enjoys close links with the Adeptus Mechanicus, and is known to be technologically innovative in its own right. Consequently, Mentors' equipment is of a superior standard in terms of reliability and technical complexity.

Metamarines
A Space Marine Chapter that participated in the 13 black crusade. the Metamarines helmets, backpacks, and shoulder guard borders are blue, and every thing else is white. Their chapter symbol is a blue sun with a skull in the center.

Minotaurs
One of the chapters created during the Cursed 21st Founding, the Minotaurs possess a reputation for being extremely xenophobic soldiers, along with being considered an unreliable and unpredictable force by many commanders within the Imperium. This chapter saw action on Rynn's World during the attempt to reclaim it from the Orks.
Minotaur power armour is yellow, with red decorations (usually warning markings). The chapter's symbol is a blue bull's head.

Mortifactors
A chapter founded during the 40th millennium from Ultramarines gene-seed. The Mortifactor's armour is painted bone and black, with the shoulder pad trim being in the company colour. The Mortifactors recruit from the night world Posul, where the nomad population practice cannibalism. The fortress monastery of the Mortifactors is adorned with skulls and bones of those that died in the service of the chapter.
T
