Titan


 * This article concerns Titan combat walkers; for the Grey Knights' homeworld see Titan (moon).

A Titan is any one of several classes of massive, crewed, robotic bipedal combat walkers fielded by the Titan Legions of the Adeptus Mechanicus' Collegia Titanica or by the Forces of Chaos' Dark Mechanicum. Originally, this term referred to many types of combat walkers used by all of the different factions of the Milky Way Galaxy. Xenos Titans have now been renamed by Imperial savants with the same titles for these war engines as the species that created them, such as the Eldar Wraithlord or the Ork Gargants. The only robotic combat walkers considered to be "true" Titans at the present time are Imperial Titans and the Chaos Titans of the Dark Mechanicum. Titans are the most sacred war machines of the Adeptus Mechanicus and they are thought by the Cult Mechanicus to be the greatest physical embodiments of the Machine God. Titans represent the real backbone of the Mechanicus' military might and are the heaviest ground units that can be deployed by the Imperium of Man's armed forces. Every Forge World of the Adeptus Mechanicus is protected by armed forces that include the Skitarii, Praetorian Servitors, and one or more of the Titan Legions of the Collegia Titanica.

Titans are considered the largest and most powerful types of war engines available to the different factions of the galaxy and have primarily featured in the Epic 40,000 series of games, though the 2007 Warhammer 40,000 supplement Apocalypse now allows the smaller Battle Titans to be used in the game. War engines vary immensely in role and size, ranging from the massive Battle Titans to super-heavy tanks and large armoured personnel transports; the only things they share in common are a large size and high damage endurance. In the Winter Assault expansion to the computer game Warhammer 40,000: Dawn of War, an ancient, fallen Imperator-class Titan (the largest type of Battle Titan) can be seen. Its prone and half-buried wreckage stretches across an entire battlefield, and the barrel assembly of its right arm-cannon alone is over 30 metres in diameter.

Titan Overview
The first Titans were built during the Age of Strife on Mars, as a way for the newborn Cult of the Mechanicum (Adeptus Mechanicus) to effectively fight its enemies in the raging Martian civil wars on the Red Planet's irradiated surface. They were later sent with the Martian colonial fleets that established the first Forge Worlds, leading to the creation of the Titan Legions - armed forces made up entirely of Titans specific to that Forge World. Most Titans stand between 15 and 60 metres (about 50 to 180 feet) tall, though the extremely powerful and very rare Emperor Titans can stand up to 150 meters (400 feet) in height. There are a variety of different classes that a Titan can belong to, but all Titan Legions ultimately serve the division of the Adeptus Mechanicus called the Collegia Titanica. Most Titan classes belong to one of three separate physical types, Scout Titans, Battle Titans and the larger and more powerful Emperor Titans. Scout Titans include many smaller, more mobile classes of the great war engines which are used for reconaissance and infantry fire support missions by most Titan Legions. Battle Titans are the most commonly deployed form of Titan and provide the backbone of any Titan Legion's strength. The rare Emperor Titans are the true kings of the battlefield in the Warhammer 40,000 universe, and the two classes of these Titans are used to provide a Titan Legion's primary offensive and defensive power.

Due to their importance and high standing in the Imperium as a result of the advanced technology used in their creation, all Titans are important enough to be given their own High Gothic names when built. This is represented in published materials by giving each one a two-word Latin name, always some venerated title or concept, usually from the Imperial Cult. Examples include Aquila Ignis, Regalis Annihilatus, Vitas Falco, Imperius Eradicus, Imperius Belladon, Apocalyptus Credo, Imperius Brontos, Imperius Excelsior, Dies Irae, Octimus Ligus, Imperius Augusta, and Imperius Dominatus. Similarly, the loss of a Titan is considered tragic and mourned by the Forge World that produced it.

Imperial Titans are unique in the sense that their computer mind-cores are sentient, albeit in a highly-erratic manner. This is in contrast with the usually non-sentient "machine spirits" or onboard computer systems found in many other Imperial war machines like tanks and armored vehicles. In the "Titan" comic, the newly connected Princeps was formally greeted by Imperius Dictatio inside its mental landscape; there was also Laudator Magnificat, which was forcibly reactivated after falling in combat. This proved disastrous: the mind-core had suffered severe psychological trauma from its "death", and began attacking everything in sight in its mindless rage.

Most Imperial Titans are roughly humanoid, but with thick lower legs, a hunched head, and an oversized torso. Forward-oriented main weapons mount directly into where the arms would be, and additional weapons are often found on the chassis. These configurations (called patterns) vary, and most Titans are built on these precepts. However the actual design of the chassis can vary greatly, so only the absolutely basic features (such as leg joints and weapon hardpoints) are constant. This is most evident in the Warhound class of Titans (the Lucius Pattern looks more geometric and broader than the Mars Pattern, which is more rounded and dog-like).

Warhound Scout Titans
Warhound-class Titans are the scouts or flanking elements of a Titan Legion and are the most common form of what are called Scout Titans by the Collegia Titanica. Appearance-wise, the Warhound differs structurally the most from other Imperial Titans; it possesses an anthropomorphized, canine-like shape, reverse-jointed legs and shoulder weapon mounts. Warhounds are lightly-armed and armoured compared to other Titans, although still fearsome compared to the more standard armoured combat vehicles deployed by the various intelligent races of the Milky Way Galaxy. They are the only Titans to be normally deployed by the Titan Legions in packs of two members, as compared to the larger Battle and Emperor Titans which usually operate alone. The Warhound Titans can only operate in a maximum of two as a result of the actions of Chaos Warhound Titans during the Horus Heresy. When the Traitor Titan Legions landed on Terra, Horus let them terrorize Terran civilians in squad-sized (10+) units of Warhounds. As a result of this blood-stained history, the Adeptus Terra during the Reformation of the Imperium after the Horus Heresy ordered the Titan Legions to never allow Warhound Titans to operate in squads large than two Titans to prevent such horrors from being perpetrated upon humanity again.

The Warhound is the first Imperial Titan that has received an official model kit from Forge World in the Warhammer 40,000 scale. Available in several patterns, classes and choice of weapons, they stand over 10 inches tall when assembled, and are 25 meters (75 feet) tall in "real life." The sourcebooks Imperial Armour and Apocalypse gives rules on the Warhound Titan, and have similar points for the Orks' Big Mek Stompa. On the battlefield, the Warhound has been proven to be very effective, with the new rules meaning that the double-barrelled Turbo Laser can destroy super-heavy enemies with ease.

Reaver Battle Titans
The Reaver-class Titan is a medium-sized Titan and the smaller of the two known classes of Battle Titans. They are considerably more durable than Warhounds, and are able to take roughly twice the amount of damage of a Warhound. This extra durability is probably a result of the unusual placement of the plasma generator on the back of the main carapace, where in most Titans the generator is located in the core of the Titan, hence the term "energy core." This placement ensures that the Reaver Titan can take more frontal damage than other Titans of the same approximate class, but is at a severe disadvantage when in cluttered environments (cities or canyons). They stand just under twice the height of a Warhound - approximately 40 metres (121.92 feet). The Reaver is described as an older design of Titan than the Warlord.

The weapons mounted are variable; they can mount some of the more powerful Battle Titan weapons, although Scout Titan weapons are more common. Most of the patterns of the Reaver carry Multiple Rocket Launchers on their carapace mounting. Unlike Warhounds, Reaver-class Titans can use close-combat weapons, which are extremely effective in Titan-scale mêlée battles. However, it is suggested that Reavers are becoming increasingly rare in Imperial armies, and it is possible that the technological secrets to their manufacture have been lost to the Adeptus Mechanicus' Forge Worlds (a common fate for the more advanced Imperial technologies). For these reasons, Reaver-class Titans usually perform fire support, avoiding direct combat.

The Mars Pattern Reaver-class Titan's carapace mounts a Multiple Rocket Launcher and Turbo-Laser Destructors on each arm. The Lucius Pattern's carapace bears a Rocket Launcher, with the arms carrying a Volcano Cannon and Gatling Blaster. There is also a fire support variant of the Lucius, with Multiple Rocket Launchers on all three mounts.

The Reaver is the second Imperial Titan that has received an official model kit from Forge World in the normal Warhammer 40,000 scale. In the (now out-of-print) game Adeptus Titanicus, Reaver Titans were given names to distinguish their weapons load-out; these were the "Goth" (fire-support Titan), the "Vandal" (inspirational/morale-boosting Titan) and the "Hun" (a tactically flexible weapons loadout).

Warlord Battle Titans
Warlord-class Titans are a larger and more powerful type of Battle Titan than its counterpart, the smaller Reaver-class. They appear to be the most common class of Battle Titan in use by the Titan Legions, and many Forge Worlds field their own patterns. The Warlord is approximately 50% larger than the aging Reaver-class Titan, putting its height at around 60 meters (approximately 182.88 feet). The Warlord Titan is also able to withstand considerably more damage than the Reaver. The Warlord-class Titan has four Battle Titan weaponry hardpoints on the shoulders and arms, allowing for a greater variety of weapon configurations. While Scout Titan weapon batteries can be mounted, Warlords usually mount Battle Titan weaponry. There is even a specialist class based on the Warlord design, the rare Psi-Titans, where psychic weaponry is added for use against daemonic entities. Warlord-class Titans can also be organised into mixed Battle Groups with Reaver-class Titans (3 of each class of Titan). These Battle Groups can be armed and used as the group's commanding senior Princeps sees fit, but they work together to complete a common objective. In general, the Princeps of the more powerful or oldest Titan in a group is the commander of the Battle Group.

The Mars Pattern Warlord mounts two Turbo-Laser Destructors on its carapace, with a Volcano Cannon and Gatling Blaster on the arms. A special variant carries a close-combat Powerfist and Gatling Blaster on its arms, plus Vortex Missile and Rocket Launchers on the caparace.

The Warlord Titans were the first to be introduced in the Epic scale, featured as a box set with 6 plastic models and Styrofoam buildings. The accompanying rules were meant for Heresy-era Titan versus Titan combat. Simple rules for interactions with vehicles and infantry were subsequently published, and the Epic Space Marine box set developed the full initial rules for infantry and vehicles. In "The Siege of the Emperor's Palace" diorama for 2000's UK Games Day and since then on display in Warhammer World a Warlord Titan features on each side. Rules for normal Warhammer 40,000-scale Warlord-class Titans were introduced in the 2007 Warhammer 40,000 supplement, Apocalypse; however no model to represent it on the field has been produced by Games Workshop or its subsidiaries thus far, encouraging players to build their own from scratch should they wish to field such a weapon in their army. The expansion Apocalypse presented rules for the Warlord Titan. It can equip with all Warhound-class Titan weapons and has access to a variety of anti-infantry and destroyer weapons, including the Vortex Missile. However, it cannot engage close targets effectively. There is currently no model for the Warhammer 40,000 range, requiring scratch construction for the modeller. If one is to construct a Warlord, it should be approximately two feet tall to be of the proper scale alongside the other models. According to the out-of-print Adeptus Titanicus game, Warlord-class Titans are sometimes differentiated according to their weaponry. A Nightgaunt Warlord has two or more assault weapons, a Deathbringer Warlord has a 'tactical' (i.e. flexible) weapon fit, a Nemesis Warlord has two or more support weapons, while an Eclipse Warlord will have given some weapon hardpoints over to inspiring religious relics of the Imperial Cult such as the Devotional Bell.

Imperius Dictatio of the "Titan" graphic novels is a standard Lucius Pattern Warlord-class Titan.

Emperor Battle Titans
The superheavy Battle Titans called Emperor Titans are subdivided into two known classes, the Imperator-class Titan and Warmonger-class Titan. Of these, the Imperator-class Emperor Titan is a general-purpose assault platform, whereas the Warmonger-class Emperor Titan is a dedicated fire-support unit with advanced fire control and targeting systems. Both are extremely powerful weapon systems and are often unmatched by an enemy force on any battlefield where they are deployed. They are loaded to the brim with pre-installed weapons, and their mounts can handle Titan weapons too big for even Battle Titans (they do not carry any of the close-combat weapons, as their sole focus is on extreme firepower). Emperor Titans are very rare, and can crush many weaker war engines. This type of Titan has legs so large they can house a full company of Adeptus Mechanicus or Imperial Guard troops for defence and assault assistance. These Titans can stand up to 150 meters (approximately 400 feet) tall.

More than a war machine, these tremendous Titans are also icons of worship to the Imperial Cult Mechanicus, as they are seen as an avatar of the Omnissah; the most noteworthy feature of an Emperor Titan is the fortified castle structure that occupies its entire upper half. These cathedrals possess ornate features like spired towers and stained glass windows. The "building" is heavily armed, and more than capable of contributing to combat. Due to the structure's prominent position on the Titan's back and shoulders, the Titan's head is hunched more than usual on the otherwise humanoid body, almost level with the arm weaponry.

Imperial Knights
Imperial Knights are combat walkers that are smaller and less advanced technologically than Titans, though they were built on the same principle, and were built by individual Imperial worlds as part of their Planetary Defence Forces (PDF). They can be seen as one-man mini-Titans. Unlike Imperial Titans, Knights use high-capacity energy cells rather than full-scale plasma reactors. Knights also benefit from power fields, which provide the same protection as Titans' void shields though they cannot be replenished in the course of a battle. Knights are the product of feudal agri-worlds within the Imperium and are, like the similar Sentinel walkers built on such planets, constructed in imitation of machines built by the Eldar - "Eldar Knights". While Sentinels herd sauropoda to be used as food sources, Knights defend them from predators. Three types were introduced in the 1990's - the Warden, Paladin and Lancer. The Wardens are defensive; armed with long-range heavy weapons and well protected with thick armour. The Paladin is fitted with a ranged weapon and a close combat weapon. The Lancer has only a single major ranged weapon but is faster and more mobile than the other types. The range was reworked in look and rules to "Paladin", "Errant" and "Lancer" types with the "Baron" as a superior command unit. A number of Knights were included in the Titan Legions box set (Epic 40,000 2nd Edition) and also feature as a hidden extra in the Final Liberation game.

Titan Armament
The weaponry carried by Titans is usually dedicated to certain tasks. Some are for targeting high-priority and well-armoured enemies, such as fortresses or armoured divisions, others are particularly effective against legions of troops and laying down devastating artillery barrages. Titan weapons are divided into two rough categories:

Scout Titan Weapons, such as the Plasma Blastgun and Vulcan Mega Bolter are weapons normally fitted to light Titans such as the Warhound. Rarely found on the largest Titans, and usually of short range, these are designed to destroy light to medium vehicles quickly, and to deal with huge masses of troops.

Battle Titan weapons have more destructive and longer-ranged weapons mounted commonly on Reaver and Warlord Titans. Most are designed to destroy other Titans, engage enemy detachments, or bring devastation to fortifications. A number of other weapons and add-ons for Titans have been described. Among them are the "Corvus Assault Pod" and "Deathstrike Cannon".

Titan Defences
Imperial Titans become increasingly well-armoured as their size increases. They also have Void Shield generators to augment existing protection, which are able to absorb destructive energy on the Titan's behalf, although there is a limit to how much they can handle. Void Shields always come in sets to maximize the likelihood of at least one remaining up after a barrage, and larger Titans may have as many as six or more fields. They cannot, however, defend against everything. For instance, non-ranged weapons (eg Titan-scale mêlée combat) and special technology like the "Titan Warp Missile", bypasses the shields entirely. It is also theoretically possible for a truly massive amount of small-arms fire to eventually bring down a shield, giving infantry a remote chance of affecting a small Titan.

Emperor Titans are also commonly equipped with point-defence weapons to protect themselves against infantry and aircraft that cannot be effectively acquired by the targetting systems of their larger-scale weaponry. Carapace-mounted Multilasers are often employed in this respect, as are more exotic weapons for dealing with aircraft.

Titan Construction
Very little is known about the methods used in the construction of Imperial Titans. It is known that many Forge Worlds are capable of producing their own patterns of these massive war engines. Of these Forge Worlds, Mars and Lucius produce the most commonly employed patterns of the major Titan classes, and other large Forge Worlds such as Ryza and the recently destroyed Gryphonne IV do so as well.

Often times, the Imperium no longer has the skills required to build new items of advanced technology, as the knowledge of their construction has been lost over the millennia due to the general decay of Imperial society. Titans, however, were not built using STC templates from the Dark Age of Technology (with one exception), and as such the Adeptus Mechanicus has maintained the necessary knowledge of how to build the majority of Titan variants. As the process of building any machine by the Mechanicus currently requires the performance of complex ceremonial rituals, the construction of a Titan is an immense undertaking, and sometimes requires many Terran centuries to complete, drawing on the skills of experienced and talented fabricators and the purest of raw materials.

Standard Template Construct Titan
The completely autonomous and artificially intelligent Castigator-class Titan was the first and only of its kind ever built. Called the Father of Titans, it was first designed during the Dark Age of Technology and its design was stored in the Standard Template Construct database, but became forgotten as time passed. The Castigator made use of highly advanced, long-lost technologies such as rapid self-repair routines, and a synthetic muscle-like locomotive system. Standing larger than even the Imperator-class Emperor Titans, the Castigator notably had its head on top of its body, matched by an elegant yet super heavy and very well-armoured chassis and impossibly-graceful movement, and it was far superior to any class of Titan utilized by the Adeptus Mechanicus or any other intelligent race in the galaxy. Its weapons included an arm-mounted melee weapon and a super-heavy, multi-barrelled cannon that fired daemons. The ability to fire daemons was later found to be due to a pact the Castigator's Machine Spirit (A.I.) had formed with the Chaos Gods. The only known Castigator-class Titan was brought down by the Grey Knights who destroyed its reactor. The portion of the STC database containing the data for the manufacture of the Castigator was destroyed by the Mechanicus because the design had proven so susceptible to Chaotic corruption.

Titan Crew
The commander of a Titan is an individual who is a member of the Adeptus Mechanicus' Collegia Titanica called the Princeps, a rare individual in that he can retain his sanity after connecting with the "Machine Spirit" (computerized artificial intelligence) of the Titan through an MIU (Mind Interlink Unit) neural interface. The Princeps controls the Titan by means of the mental link provided by the MIU. The Princeps is seated on a command throne in the Titan's head, along with several system controllers and second-line bridge officers called Moderati who act as the Titan's command crew. Lower ranking officers called Steersmen often control the Titan's most basic functions like locomotion. The number of Moderati and Steersmen depends on the size of the Titan, and their duties involve secondary tasks like regulating and maintaining the massive walker's weapons and other systems, as well as monitoring and interpreting readings from the Titan's auspexes (complex arrays of various types of sensors). Other Titan crew members include various engineers (usually Adeptus Mechanicus Tech-priests) for repair work and the necessary blessings required by the Cult Mechanicus, and Servitors who are set on the more mundane tasks required by the Titan. Some of the largest Titans also have Adeptus Mechanicus armed forces like Skitarii or Praetorian Servitors on board in case an enemy attempts to board and take control of or destroy the Titan.

Chaos Titans
During the Horus Heresy, half of the Adeptus Mechanicus, including several hundred Titan Legions, turned to the worship of Chaos, taking their mighty war machines with them. Chaos Titans are usually similar to their Imperial counterparts, but their long exposure to the warping influence of Chaos has changed many of them. In some cases, the crew has merged with their machine, making it impossible to tell where one ends and the other begins. Other crews have given themselves and their weapons over solely to one of the four great Ruinous Powers of Chaos.

Feral Titan
Feral-class Titans are twisted versions of the Imperial Warhound-class Titan and are used for the same tactical purposes by the Forces of Chaos. To their eternal shame, the Titan Legions bear the stain of disloyalty to the Emperor like so many other branches of the Imperial armed forces. Like the Legio Astartes, many of the Titan Legions also sided with Horus against the Emperor during the dark days of the Horus Heresy, and eventually fled to the dark refuge known as the Eye of Terror when their master was defeated. Within the Forces of Chaos, the dreaded Chaotic Warhound-class Titans, reclassified as Feral-class Titans by the Imperium, have seen millennia of service in the Traitor Titan Legions' pursuit of the Long War against the Imperium of Man, becoming utterly corrupted by the daemonic powers of the Warp and the fickle favour granted to these vile war machines by the Ruinous Powers. Many of these dreaded war machines easily date back to long before the Horus Heresy and have had their Machine Spirits wholly corrupted and possessed by the Warp-touched powers of Chaos. The Titan's Machine Spirit and its damned crew become possessed by daemons and are doomed to serve the will of the Chaos Gods in battle for all eternity.

Ravager Titan
Ravager-class Titans are the Chaos versions of the Imperial Reaver-class Titan. Within the Forces of Chaos, the Reaver-class Titans are ancient and irreplaceable relics left over from the days of the Horus Heresy. To differentiate these corrupted Reavers from their Imperial counterparts, the Imperium has redesignated these war engines Ravager-class Titans, though this name is rarely used. They are the remnants of those Traitor Titan Legions who sided with the renegade Warmaster Horus during those dark times and whose blasphemous names still echo with dread thousands of Terran years later. The majority of these monstrous war engines have seen millennia of service with the Chaos forces and have long since become utterly corrupted by the touch of the Ruinous Powers and the Warp. Others are salvaged Imperial war engines taken from the battlefield as spoils of war, much to the eternal shame of their former masters. These captured Battle Titans have been subjected to bloody rituals in order to consecrate them to the service of the Chaos Gods. Over time, Chaos Reaver Battle Titans become an amalgam of daemon and machine, their once living crews fused to the controls and their souls subsumed into the Titan's tainted Machine Spirit, the war machine itself now a single being dedicated to destruction and butchery, reborn to spend an eternity of battle in servitude to Chaos. Revered and tended to by the Warp-tainted Hereteks of the Dark Mechanicus, lesser servants of the damned view these towering engines of destruction as incarnate gods of fire and death. Many of the lesser beings who serve Chaos make obeisance to them, offering sacrifices of captives and even their own lives to slake these towering monsters' thirst for blood.

Chaos Warlord Titans
Amongst the Forces of Chaos, Warlord-class Chaos Titans are ancient and irreplaceable relics left over from the days of the Horus Heresy. They are the remnants of those Traitor Titan Legions who sided with the Renegade Warmaster Horus during those dark times and whose blasphemous names still echo with dread thousands of Terran years later. The majority of these monstrous war engines have seen millennia of service with Chaotic forces and have long since become utterly corrupted by the touch of the Ruinous Powers and the Warp. To differentiate these corrupted Warlords from their Imperial counterparts, the Imperium has designated these war machines with different class names that have been happily adopted by these Titans' Renegade crews. The Chaos Warlord-class Titan has 4 different variants depending on which Ruinous Power of Chaos the Titan is aligned with. Even though there are different versions of the Chaos-altered Warlord-class Titan, the most commonly seen variant operating with the Forces of Chaos is the Banelord Titan.
 * The Banelord-class Titan is dedicated to the Chaos God Khorne and has been modified with a long tail that ends in a large cannon of various types, while another such cannon protrudes from the Titan's daemonic mouth. The Banelord also has access to three special weapons: a Havoc Missile Rack, a Hellstrike Cannon and a Doomfist. This is the most common Chaos Warlord Titan.
 * The Plaguelord-class Titan is dedicated to the Chaos God Nurgle.
 * The Painlord-class Titan is dedicated to the Chaos God Slaanesh.
 * The Warplord-class Titan is dedicated to the Chaos God Tzeentch.

Chaos Emperor Titans
Imperator-class and Warmonger-class Emperor Titans are the greatest war engines ever created by the Imperium of Man. Those few Emperor-grade Battle Titans to fall into the hands of the Traitor Legions during the Horus Heresy that still exist today are rarely deployed on the battlefield and only when the Forces of Chaos have decided that they are willing to pay any cost to secure a victory. Most Chaos Emperor Titans have been possessed by Greater Daemons which have transformed these great war engines into towering leviathans of Warp-corrupted steel and Adamantium, a true incarnation of the power of Chaos in the material realm.

Ork Gargants
The Ork equivalent of a Titan is called a Gargant. Gargants are as much idols of the savage Ork Gods, Gork and Mork, as they are engines of destruction. Big Mek Orks receive a divine vision of sorts from Gork (or possibly Mork), and set out to bring that vision to life in the artistic medium of thick armor plates, smoke-belching engines, and lots and lots of very large guns. This quickly spreads amongst other Big Meks in the area, and soon Gargants spring up all over the place. The construction of Gargants is one of the typical signs of an impending WAAAGH! from an Ork-held system.

In an Ork warband, there can exist Gargants and Gargant-like mecha war machines all the way from one-Gretchin (small, greenskinned goblinoid creatures closely related to Orks) Killa Kans which are the Ork equivalent of the Space Marine Dreadnoughts to the vast armoured behemoths of the Mega-Gargants. From smallest to largest, the most typical machines of these type include:

Stompas
Stompas are neither war engines nor Titans proper but rather large, armoured fighting vehicles built as roughly Ork-shaped effigies. They are armed with both long- and short-range weaponry and are used in the same manner as heavy tanks. Supa-Stompas are significantly more powerful than regular Stompas, and count as war engines. They can mount two of the weapons that are carried on the larger Gargants and can be seen as equivalent in firepower to a Warhound-class Scout Titan of the Imperium.

Gargants
Gargants and Great Gargants are the archetypal Ork Titans. They are massive constructions broad and squat compared to an Imperial Titan. They are fitted with many batteries of guns and also tend to have at least one mega-weapon. They are roughly equivalent to Reaver and Warlord Titans, respectively.

Mega-Gargant
The Mega-Gargant is a very rare, super-large Gargant on a par in size with the Imperator and Warmonger-class Emperor Titans, though not as powerful. It carries a large number and variety of weapons including the Mega-Dropper. Unlike the other Gargants which shuffle forward on their short mechanical legs, the Mega-Gargant is actually a tracked vehicle; essentially it is a mobile Ork fortress.

Big Mek Stompas/Gargants
Often a Big Mek Ork will not be satisfied with the production of Battlewagons, and will create his own Stompa or Gargant. These Titan-like monstrosities mount the latest Mek weaponry, such as the 'Lifta-droppa'. The size of the Stompa or Gargant depends on how much influence the Mek has, how much raw materials there are, and who they are 'constructing' it with. Occasionally, two Meks may work together, combining their love of tinkering to produce a new Gargant on their own initiative or because they have been commanded to do so by a larger, tougher Ork Warboss or Warlord.

Construction
Ork Gargants are an extremely varied lot, with no two ever being exactly alike, as is common with seemingly slapdash Ork technology. Thanks to the frenzied imaginations of the Mekboyz building them, Ork weapons tend to be haphazard, unreliable and noisy. When they work, however, they can inflict gruesome damage. Gargants are commonly equipped with at least one close-combat weapon, because charging in and bashing heads is considered to be a very "Orky" thing to do.

For defence, Gargants have Power Fields which are the Ork equivalent of an Imperial Titan's Void Shields; however, while Gargants tend to have more intense and reflective Power Fields that an Imperial Titan, they cannot regenerate these during the battle like a Titan is able to do.

Orks do not rely on auto-systems to the same extent as the other intelligent races, and Gargants carry a large crew of both Orks and Gretchins. The crew is led by a Kaptin, who relays orders through a body of officers. A speaking-tube is the preferred method of communication within a Gargant. Each officer is in charge of one section of the Gargant, be it a weapon, the magazine, the engine room, or any other chambers. Under the officer is a crew of Orks and Gretchins who carry out the orders passed down to them. Repair crews are composed of Gretchins, whose smaller build suits them for crawling through cramped spaces armed with wrenches and oily rags.

Compared to Imperial Titans, Ork Gargants have weaker armour and comparatively shorter-ranged weaponry. Nevertheless, Gargants are extremely difficult to destroy due to their dense (albeit crude) construction (in games, this is represented by Gargants having more structure points). While Gargants do not suffer from potentially fatal plasma reactor meltdowns, they are particularly vulnerable to fires and magazine explosions.

Eldar Titans
Eldar Titans are quick and nimble machines of war. They are thinly armoured but despite their frailty, Eldar Titans can pack a mean offensive punch, and can move about the battlefield with frightening speed, thanks to their Jump Jets.

Instead of the Void Shields used by other intelligent races' Titans, the Eldar rely upon advanced holographic field generators which in conjunction with speed make their Titans extremely difficult to target. However, holo-fields do not actually deflect enemy firepower, so Eldar Titans are even more vulnerable should they suffer hits. Eldar Titans are also unlike those of other races in that they are powered by the actual spirits of individual Eldar contained in a core of psycho-reactive material called Wraithbone, which is a material also used in the construction of the Titan's carapace due to its light weight and great durability. The pilots of the machines link psychically with the Eldar spirits in their core, rather like the Princeps of an Imperial Titan linking to its Artifical Intelligence Machine Spirit; and this allows the Eldar pilot to control the Titan like an extension of his own body. The Eldar spirits, however, enhance the skills of the pilot as well as the Eldar's already superhuman reflexes and reaction times.

There are three types of Eldar Titans:


 * The Revenant is a relatively light war machine, roughly equivalent to an Imperial Warhound, though much more agile. They are best suited for lightning-fast raids on enemy lines, using their speed to retreat before a counter-offensive can be mounted. A model of this Titan has been created by Forge World. It can come armed with either Pulsars or Sonic Lances. Like Imperial Warhound Titans, Eldar Revenant Titans are often deployed in pairs. The pilots of these pairs are usually siblings, their blood ties psychically linking them together for thought-speed communication during combat.


 * The Phantom is a more massive Eldar war machine capable of taking on its Imperial equivalents. What makes Phantom Titans distinctive from those of lesser races is their crew. In addition to the living, the souls and memories of ancient Eldar warriors are maintained in the wraithbone matrix of the Titan.


 * The Warlock is a refinement of the Phantom. Its wraithbone core hosts the spirits of late Seers and Warlocks, focusing their psychic power into a near-unstoppable engine of destruction.

Tyranid Bio-Titans
Bio-Titans are more than exceptionally large Tyranid biomorphs, they are on a par with the Titans deployed by the other intelligent races and were created by the Tyranid Hive Fleets to directly compete with the similar massive war engines they encountered among the other races of the Milky Way Galaxy. Bio-Titans are deployed in the final stages of the assimilation of a planet into a Tyranid Hive Fleet's biomass.

While their supersized biomechanical weaponry is potent, Bio-Titans are feared mainly for their extreme effectiveness in close combat against enemy Titans and other war engines. They are also considerably faster than Titans of other races; as a result Bio-Titans often charge towards the enemy. Their ripper tentacles can neutralize enemy Titan close combat weapons, while monstrous claws will make short work of Titan hulls.

Bio-Titans do not generate void shields like those of the Imperial Titans or Ork Gargants; however they made up for this by being able to "regenerate" or self-heal. Bio-Titans can generate bio-plasma fields to make them less vulnerable to sniping from Imperial Volcano Cannons, though this ability was present in early Bio-Titans produced by the Tyranids but newer iterations of Bio-Titans recently encountered by Imperial forces do not seem to possess this ability.

Examples of Tyranid Bio-Titans include the Vituperator, the terrifying Hierophant and the even more monstrous Hydraphant. They are roughly equivalent to the Imperial Warhound, Reaver, and Warlord Titans, respectively.

Regular Tyranid biomorphs (not war engines, let alone Titans) include the tank-sized burrowing Trygon and the winged Harridan (a war engine but not considered a Titan). The Heirodule was used as the name of the smaller Bio-Titan (the Hierophant was the larger Titan) when the model range was released in November 1997, however the Heirodule is now just a biomorph construction.

A specialist breed of Bio-Titan is the Dominatrix, a powerful Hive node that can use its malign intellect to command the hordes of lesser biomorphs around itself with ghastly efficiency. In the hierarchy of Tyranids, they are the supreme commanders of the battlefield and second only to the shipbound Tyranid Norn-Queens themselves.

Necron
The Tomb Stalker is the most fearsome, tireless guardian machine left by the Necrons to provide silent vigil over their Tomb Worlds. A Tomb Stalker is an enormous centipede-like construct that teems with multiple legs and is possessed of a murderous will, the Necron equivalent of an Imperial Titan. It has the ability to burrow through solid ground and can trail its prey using its powerful senses, detecting the rhythm of a faint heartbeat even through solid rock. Its immense size and innate ability to regenerate because of its Necrodermis shell makes it a nearly indestructible creature, fighting on even when severely damaged or dismembered.
