Codex/Demons

Zombies
Possessed by the influence of Hell, these once-human underlings that follow in Hell's ranks are those that have been corrupted and deceived by its power, forsaking their own humanity. Those who have fully succumbed to Hell's control cannot be saved, becoming mindless, grotesque contortions of their former selves.

Imp
Scavengers of the underworld, Imps are among the most common of beasts found on the scorched surface of the Hellscape. Lesser demons of Hell, the Imp possesses limited intelligence, drive only by a hunter's impulse to seek out prey - a task for which the Imp is naturally suited due to its innate capacity for violence. As a result of these attributes, the Imp makes for an ideal footsoldier and is oft deployed in the warring legions of Hell, easily manipulated and controlled by commanding highborne demons at the behest of the sovereign chapters. It is common for the Imp to appear at the frontline of an offensive attack, an expendable resource unleashed in great numbers to overcome and break through the enemy front.

Soldiers
Once frontline infantry fighting to protect Earth from the demon invasion, the Hell Soldiers have been claimed by darkness, turning them against their fellow soldiers in the midst of battle.

Gargoyle
Like their Imp brethren, the Gargoyle is an agile, relentless pack hunter. Native to the Sentinel world, this beast has plagued the Sentinel Guard for centuries. As one of the few demon breeds that could bypass the walled defenses of Sentinel Prime, the Gargoyle could appear without warning and claim hapless townspeople before disappearing into the wasteland. Only the most skilled marksman of the Night Sentinels could intercept this aerial threat, a peril which demanded an ever vigilant watch over the city's perimeter.

Lost Soul
The Lost Soul has its origins among the Damned - former humans who have fallen from the mortal world, doomed to an unliving eternity as sin-branded slaves of Hell. The Damned are seemingly endless in number, their populations growing by the thousands with each rise of the black sun. For many, the tortuous existence of crushing slave labor is all that awaits. The bodies of the Damned are brittle, and those who become broken in labor - their bodies ruined, dismembered, or otherwise incapable of servitude - are transported to the pits where their souls must be extracted for further use. Those fortunate enough to escape this process are what inevitably become Lost Souls; their spirits transmogrified into physical form. The Lost Soul knows only madness, its memory a haunted image of its former mortal life. These creatures live a fleeting existence, roaming mindlessly, seeking only that which can grant them a final death.

Maykr Drones
Urdak's population is mainly comprised of Drones, beings that exist as extensions of the Khan Maykr's will. Though each is endowed with their own unique identity they remain biologically unable to resist a command from their Khan, and so function in a perfectly synchronized colony system. Drones never leave Urdak, their bodies not yet mature enough to avoid harm while crossing dimensions.

Arachnotrons
Arachnotrons are built with genetic material recovered from the remains of the original Spider Mastermind, bio-engineered for cyber-augmentation. While it's actual body exhibits only limited mobility, the oddly cerebral qualities of the Arachnotron make it a prime candidate for the impulse-controlled prosthetic frame that it now permanently inhabits. The UAC facility responsible for the Arachnotron's creation, intending to engineer and weaponize demons of their own design, was overrun after an outbreak occured inside of it's assembly plant, killing everyone inside. The facility, still operating under the directive of the administrative AI, continues to manufacture Arachnotrons autonomously.

Cacodemon
Hunters of the Sloughlands, the Cacodemon lurks in the bottomless and murky depths of Hell in search of easy prey. An aimless wanderer, the Cacodemon is mostly devoid of cognitive ability, sensory awareness, and otherwise commonly occuring impulses. Driven only by a singular desire to feed, the Cacodemon is likely to appear wherever there is flesh to be consumed, bringing with it an insatiable propensity for hunger. It is said that the Cacodemon bears some resmblance to the cycloptic titans of ancient Hell lore, leading Sentinel scholars to believe that the forgotten titans may yet live on in some disembodied form.

Carcass
The product of inhuman bio-mechanical engineering, the Carcass was created in the remote labs of the Cultist enclave. Neither truly living nor dead, it exists in a state of partial re-animation - it's cybernetic armature simulating a living impulse within a decaying organic host. Devised as a means of extending the soldier's usefulness in combat after death, the unliving host can only be destroyed by severing the body from it's cybernetic implants.

Dread Knight
A variation of the Hell Knight breed, the Dread Knight has been modified and hardwired for aggression. Armed with an exo-prothesis powering energy blade augments, the Dread Knight is the lethal result of UAC Cultist engineering. Epinephrine regulations modulate the Dread Knight with an unbroken flow of rage-addled ardenaline, while it's endorphin receptors have been synchronized to respond with the use of it's arm-mounted blades. With each kill, the Dread Knight is injected with a flood of artifical dopamine. As a result of it's augmentation, the Dread Knight is driven by a biochemically engineered state of pure, unbroken rage - a suffering for which respite can only be found in the act of the kill.

Hell Knight
The Hell Knight, warrior beast among demons, has earned it's place over the millennia in service of the eternal Archdemons. As imposed by the sovereign houses, Hell Knights have long served as barbaric enforcers of the netherworld, impelling lesser demons by way of brutality. Rare among demon-kind for it's innate regard for primal orders of hierarchy, the Hell Knight exhibits adherence to the prevailing rule of it's demonlord masters. Requiring little compulsion on behalf of it's highborne masters, Hell Knights readily serve the Elder Hell-gods for the extent of their lifespans, reaping great satisfaction in the way of war and desecration.

Mancubus
The Mancubus, hulking behemoth of the demon world, bears notable difference from those of it's kind first encountered by the UAC expedition team on Mars. Unlike it's brethren which wore a naturally occuring armored carapace, this variation shows clear signs of pre-existing man-made modifications. Armor-plating augmentation to it's exterior and a sophisicated arm-mounted weapon system indicate a clear intent to upgrade and weaponize the fighting capacity of the Mancubus, whose heavy stature and resilience make it a formidable threat in battle.

Pinky
As Hell emerged on Earth, the Pinky began to appear on terrestial soil in great number, rapidly becoming the bane of existence to ARC military fortifications. Utilizing it's armored frontal carapace, the Pinky is able to penerate defensive encmapments, breaking through walled defenses and using it's ramming ability to upturn and immobilize armored vehicles. ARC deployments, dependant on their ability to hold the line against enroaching forces of Hell, could be disrupted and even overtaken by a single Pinky, were it able to penerate and break through their defensive matrix, allowing a greater demon influx to pour in after it. The ARC rapidly prioritized the target status of the Pinky, issuing high-range bombardment to prevent the Pinky from gaining proximity.

Prowler
A creature of darkness, the Prowler hunts from the shadows, preferring stealth and concealment to open conflict. Imbued with parietal infravision, the Prowler is able to see that which is unseen to the naked eye. Known among the Sentinels as 'the Nightstalker', the Prowler's preternatural sense of sight makes it a lethal hunter, capable of tracking it's prey even in the pitchest black of dark. Believed to be peripherally descendant to the lesser Imp broodling, the Prowler is rarely seen in groups, forsaking pack-hunting for the precision of the solitary pursuit.

Revenant
The Revenant program, a bio-weapon experiment utilizing re-animated necrotic human tissue, was believed to have been destroyed with the collapse of the UAC facility on Mas. However, the emergence of the Cultist enclaves on Earth - former UAC deviations now under Hell's direct control - have begun work on a second wave of production of the Revenant program. While much of the platform's existing weapon payload is preserved as originally designed, the cyber-neural programming has undergone modification. Patterned signals are wired to the host's frontal cortex, which in turn simulate a state of frenzied, unrestrained bloodlust. While these signals are active, the host is incapable of thinking or feeling anything but a singular compulsion to inflict death and violence on the living.

Whiplash
A scavenger of the Hellscape, the Whiplash creature was first discovered by UAC expedition teams in the black desert of the Sanctum Wastelands. These elusive, serpentine demons move with great speed and agility. They are capable of striking from a great distance with retractable bladed whips concealed from within their forearms. This particular demon breed became an object of great interest to the UAC engineers on Earth, while attempts to capture live specimens of this nimble and unpredictable creature proved to be exceptionally dangerous. After successfully acquiring living specimens, researchers implemented cybernetic augmentations designed to enhance the Whiplash's innate strength and lethality.
