The following is a complete list of all Space Marine Chapters created by our authors here on the Warhammer 40,000 Fanon Wiki. This list also includes Renegade Chapters of Chaos Space Marines as well as those Space Marine Chapters considered Excommunicate Traitoris by the High Lords of Terra, whether they serve the Ruinous Powers or not. This list does not include those Space Marine Chapters from the Imperium of Blood or Space Marine Legions of the Legiones Astartes community projects.
The Armor Fiends are a crafty renegade chapter founded in the 20th founding. Rushed out as a stop gap measure, their turn away from the Imperium was inevitable. The chapter was a mess from the start. Being forced in to combat with another chapter that simply were not ready for combat alone. Since then, the Armor Fiends have fought many sieges for and against the Imperium.
The Crimson Dragoons are a Codex Astartes Space Marine Chapter created from unknown gene-seed stock during one of the early Foundings. The Chapter is mostly involved in battling against Eldar, however they also fight against Orks, Chaos and Tau. The Chapter's current location is unknown, however some say they are fighting against the Tyranids in the Ultima Segmentum, which is where they were last seen.
The Axe Brothers are a devoted, noble and mighty Chapter, having battled throughout their millennia long existence from their Ultramarines Legion roots, to the current date and timeline. Forged in the fires of war and betrayal of the Horus Heresy, they were created following the subsequent sundering of the original Space Marine Legions during the Second Founding in 001.M32. The newly created Axe Brothers Chapter were placed under the command of Legion-Captain Roman, the former commander of the Ultramarines' 7th Company. After slaying the World Eaters Chaos Champion Kronlovk, he proved himself a worthy leader and was giving the right to lead his very own Chapter after the Horus Heresy.
The Basilisks are a secretive Chapter created from unknown origins and Founding. This Chapter's arrival is often considered an ill omen by their fellow Astartes, and as a sign of the end for many Imperial Citizens. Allegedly cursed, they specialise only in one form of combat; Scorched Earth tactics. Utilising fire, rad weapons, and chem munitions, they salt the earth and slay any in their path.
The Blood Dragons are a Successor Chapter of the vaunted Blood Angels, and serve as one of the wardens of the far-flung Tyrest Sector, containing worlds of importance to the Imperium, but imperiled by threats on all fronts.
The Brotherhood of the Mammoth was at one point a doomed company, lost and stranded upon a feral death world known as Kor, thought lost to time. They were reclaimed, after generations had passed, and now these feral space marines serve the Emperor once again.
The Castigators are a rare Successor Chapter of the now-extinct Black Consuls Chapter, created during the 14th Founding sometime between 975-991.M31. The Castigators have earned a reputation as staunch and stalwart guardians of the Imperium in the millennia since their inception.
An enigmatic and ancient Chapter of Space Marines, the Dune Dragons have long been a mystery amongst their fellow Astartes. Hailing from the sweeping deserts of the Feudal World of Ak'Une, known as Isisar Majoris in the standard Imperial Lexicon, the Dune Dragons are warriors who prize swiftness, durability, and precision above all else in battle. Soaring into battle within their vast Land Speeder squadrons, or crushing through enemy ranks with their mighty Predator Tank formations, the Dune Dragons place the utmost faith in the Machine Spirit, venerating the Omnissiah equally with the Emperor, holding them as parts of the same being.
The Dragons Sanguinaris are a non-Codex Space Marine Chapter composed entirely of Primaris Space Marines, created in the 27th 'Ultima' Founding, and descended from the Blood Angels. They favour a 'soften-and-smash' approach to battle, deploying Jaberwockis (Hellblaster units) from Wyrms (Land Raiders) alongside Amphitheres (stormraven gunships) and Wyverns (Interceptors). Then in the middle of the fight, once the enemy force has been weakened and diminished by the initial forces, drop pods descend from the sky behind enemy lines, and deploy Kholeghan squads (Primaris Reivers).
Once a fiercely loyal Chapter of the Dark Angel's Unforgiven, the Fire Lions turned from the Imperium they had sworn to uphold during the dark days of the Nova Terra Interregnum, supporting those who opposed the establishment of a theocratic state and succession from the Imperium and its new Imperial Cult. However, after the Ur-Council crumbled, the Fire Lions were forced to flee with scores of refugee fleets to the very borders of Segementum Pacificus. It is said by Imperial scholars that the Fire Lions still reside in the deep space at the edge of the Galaxy, having formed a small fleet based nation-state based on the edicts of the Imperial Truth. Now little more than vagabonds and pirates, the Fire Lions seek to rekindle a rebirth in the Imperium's golden age of reason through brutal terror strikes and by seeding the stars with agents of doubt.
The Golden Reclaimers are an Imperial Fists successor chapter formed in the Twenty-Sixth Founding. A newer group of Space Marines, they have accomplished a great deal in their few centuries of existence and are known for their loyalty towards Mankind. They were created in 738.M41 in order to help seize a number of worlds that the Imperium had lost contact with over the years, hence their title as 'Reclaimers'. The Chapter would end up dealing with a number of foes during their early years and became particularly adept in the art of urban warfare as world after world was reclaimed in the name of the Emperor.
The Grave Bearers are a successor to The Black Templars and despise Psykers. The Grave Bearers derive their name from the ritual practice of engraving the names of fallen brothers on the inside of their armor. The battle brother is cremated and the armor is past on to the next. Since there is no body to bury and no headstone to mark, the armor itself becomes the grave for the fallen brother and the new owner has to carry the burden and honor of those that wore it before him.
The Jade Falcons are a Successor Chapter of the venerable Dark Angels. They were created during the 3rd Founding from the gene-stock of Lion El'Jonson. Like their fellow Unforgiven Chapters, they continue with their secret hunt for the Fallen Angels, scouring the galaxy for their erstwhile kin, so that they can grant them extreme unction at the hands of their forebear's Interrogator-Chaplains.
The Knights of Sanguinor are one of the Second Founding Chapters, created from the vaunted Blood Angels, their initial founding members were primarily made up of Legionaries from the 167th Company. They are well-known across the galaxy for their stealthy nature in battle, and didn't fear for the curse of the flawed gene-seed they carry. The Knights of Sanguinor are amongst the longest-living of the Adeptus Astartes, with some of the Chapter's Space Marines having served the Emperor of Mankind for over a thousand standard years.
The Knights of the Lion are a Successor Chapter of the venerable Dark Angels. They claim to be one of the ancient Chapters created during the Second Founding in 001.M32. They are considered to be amongst some of the greatest of combatants against Chaos and other renegades. Their outwardly rowdy and somewhat friendly exterior for a Space Marine is unusual for a descendant of the First legion, however, their enemies would be wise not to confuse the Knights' jolly demeanour for weakness or mercy. On the battlefield the Knights of the Lion are relentless -- their enemies defeated in battle are often completely obliterated -- as the Knights utilise Terminators, jump packs and Drop Pods to ensnare and engulf their foe. Rarely does an enemy warlord or opposing commander escape the judgement of this Chapter of the Unforgiven. The Chapter has taken record numbers of fallen back to Lionswatch and their Interrogator-Chaplains are second only to the Dark Angels themselves at extracting confessions.
The Phoenix Knights are a newer Founding Chapter, created from the gene-stock of the venerable Dark Angels during the Twenty-Sixth Founding. Initially named the Knights of Vengeance, this Unforgiven Chapter faced an inauspicious beginning, and would have been destroyed in its entirety when they were attacked by a large Chaos warfleet and beset upon by daemons during a routine warp jump. Though the majority of the newly created Chapter's most experienced Astartes perished, they managed to turn the tide and snatch victory from the jaws of defeat. Displaced by the vagaries of the Warp, the Chapter reemerged into realspace after missing for nearly three centuries. Their exposure to the energies of the Warp also caused mutations in the gene-seed, the full extent and implication of which were not yet clear. Therefore, the Knights of Vengeance were declared corrupt and unworthy as inheritors of the Lion, and so, the Dark Angels severed all ties with their former kin. In their darkest hour, the Ultramarines offered to help rebuild the shattered Chapter as well as stabilising the minor degradation in their gene-seed. Thus, the Chapter rose from the ashes like the fiery bird of ancient legends -- the Phoenix -- thus, the Knights of Vengeance forged a new identity and became the Phoenix Knights.
The Scarlet Skulls are a fleet-based Space Marine Chapter of unknown Founding and origin. Shrouded in mystery, this Chapter has served the Imperium of Man for millennia. The Scarlet Skulls do not shrink from battling the enemies of Mankind, and reserve a special grudge for renegades and corsairs. Throughout their millennia of service, their constant enemies have been Dark Eldar and Chaos Space Marine renegade Chapters such as the Red Corsairs. The Scarlet Skulls specialize in boarding actions and planetary raids, but maintain a mechanized company in the event of protracted ground battles.
The Shadow Warriors are a brutal Raven Guard Successor Chapter that was created during the 24th Founding, sometime in the early 38th Millennium. Hailing from the verdant jungle world of Rehua I, located in the Segmentum Ultima, the Shadow Warriors have been ranked among the most brutal and fearsome of the Raven Guard Successors. Inheriting their strategic prowess from the Raven Guard, the Shadow Warriors combine vicious assaults with cunning tactics and guerrilla warfare, exploiting the enemy's weak spots with lightning fast deployment and finishing them off with brutal efficiency. While these marines inherit the logistical aspect of their battlefield doctrine from the Raven Guard, they carry on the violent and cunning traditions of the tribes of their home world. Many observers often remark on the terrible suffering they bring to their enemies, utilizing close combat brutality to tear apart xenos and heretic alike.
The Sons of Mortis are a bellicose and violent Chapter, believed to have been created sometime during the early 32nd Millennium during the 3rd Founding. This Chapter is a rare example where its Astartes' beliefs are in conflict with official Administratum records, as they claim to be descended from the Imperial Fists' Primarch Rogal Dorn. However, the Chapter's gene-seed received by the Magos Bioligis hint at darker origins that harken back to the Age of Darkness, during the tumultuous times of the Horus Heresy in the 31st Millennium. This aloof and often brutal Chapter possesses an unsavoury reputation for having bloody-handed warriors that live to fight for the kill. Their detractors whisper that the Sons of Mortis would turn their backs on the Imperium of Man just for the chance to shed blood, however, this is merely circumstantial and hearsay, but there bloody ways often speaks volumes for them.
The Sons of Odin are a Loyalist Successor Chapter believed to have been created during the 3rd Founding in 001.M32. The Astartes of this Chapter are the proud scions of Roboute Guilliman. Though they share little in common with their forebears' culture and traditions, they have garnered a reputation an unbreakable sense of honour and a history of unparalleled skill at arms. In battle, their ferocious mien has often seen them carry the day, when all odds have been stacked against them. The Sons of Odin are unafraid of battles of attrition or mutual destruction, relying on the abilities of their Battle-Brothers to overcome and endure anything the enemy can throw at them. At times this has proven to be a flaw, as the Chapter has a predilection to fight on once engaged where its better strategic judgment might have otherwise prevailed before its bloodlust was roused.
The Storm Sons are a rare Successor Chapter of the venerable, highly mobile and feared White Scars Chapter. Created sometime during the 24th Founding in the 39th Millennium, the Storm Sons, like their forebears, enact swift and brutal justice against those who transgress against the Emperor and his Imperium of Man.
The Turquoise Protectors are a loyalist, partially Codex Astartes compliant Space Marine Chapter that was founded during the Macharian Crusade, the 25th founding, at 393.M41. They are a successor chapter of White Scars, but a second legion is also suspected of having a connection with them. Turquoise Protectors excel at ship-to-ship warfare, airborne assaults, warfare against daemons and Space Hulk purges as they can resist the effects of the warp more than an average Adeptus Astartes can. Led by Lord-Protector Kür-Shad, Turquoise Protectors vigilantly protect the Imperium of Man against any threat. They never waver, they never resign!
