The Knightmare Frame are humanoid-shaped armored fighting machines developed at first by the Holy Britannian Empire, and then later by other countries, the unit is first deployed in direct combat during the Britannian Invasion of Japan. During this Invasion the Knightmare Frame proves itself to be far superior to any other fighting machine at the time, with it easily able to outmaneuver and outfight Japanese tanks. After the Invasion, the Knightmare Frame becomes the main fighting unit of the Britannian Military replacing the now obsolete main battle tanks of their forces. Over time the Knightmare Frame has advanced to become the main weapon of several different nations.


(Paraphrased from the Code Geass Wiki Knightmare Frame Article)

Knightmare Frames often have a humanoid shape and are usually between four and five meters tall. In addition to the standard range of bipedal movement, Knightmare Frames are equipped with Landspinners, self-propelled roller skates attached to the ankles of the machines, which allow them to achieve high mobility and speeds on most terrain. Visual data is gathered through Factsphere sensors, which have the thermographic capability and an array of other data-collection functions which are collated in real-time. Factspheres are commonly protected under a layer of armor which can be retracted to improve system sensitivity. Knightmare Frames are piloted from a cockpit set in the protruding 'humpback' in the unit. The cockpit is a self-contained control center which can be ejected in case of emergency.

Knightmare Frames are powered by the Yggdrasil Drive, a fictional energy source. Its centerpiece is a Sakuradite device called the Core Luminous, wherein a cube of unknown composition is weightlessly suspended. The cube revolves at high speeds during a state of drive activation known as Yggdrasil Resonance, apparently involved in the conduction of electricity. The technology is named after the Yggdrasil, the world tree of Norse mythology. The drive is recharged through a Sakuradite energy filler.

Knightmare Frames are typically armed with rocket-propelled anchors called Slash Harkens and a number of other weapons. Mass-production models usually carry handheld rifles and a number of Chaos Mines, cylindrical air burst grenades that spray deadly shrapnel over a small area. Less common equipment, though more widespread as the series progresses, are Maser Vibration Swords (MVS), a form of vibroblade which oscillates at a high ratio to cut through almost anything, and Hadron Cannons, powerful energy cannons which can obliterate almost anything in their path. Late in 2017, Float Systems, devices which allow Knighmares to fly, is introduced, and by 2018 also fall into common use.


The creation of Knightmare Frames is roughly divided into nine different ages, which mark the birth of a new kind of weapon platform and its evolution into a full-fledged combat system.

First Age: Infancy[]

The beginnings of the Knightmare Frame came from the creation of 'emergency survival cockpits' for conventional armored vehicles. Equipped with rocket engines to fly the crew away from the wreck, the contraptions were soon equipped with artificial legs to allow greater mobility. The limited room inside said vehicles restricted the number of legs to two. Though not a weapon in any sense of the word, the 'walking cockpits' provided the base form for their successors.

Second Age: Turning Point[]

Several years later, the creation of several common Knightmare Frame technologies, such as the Factspheres and Landspinners, lead to the funding for Knightmare Frame prototypes. However, the new technologies performed erratically, and the research was outsourced to military-based robotics projects and social-oriented programs. The former was assigned to a Britannian Army Special Division, the 'Special Dispatch Guidance System Division', while the latter went in the hands of a private group, the Ashford Foundation. The foundation implemented technologies related to training and education, enabling the entire Knightmare Frame program to make progress fluidly.

The bipedal weapon was nicknamed 'Knightmare' by the Army, but its non-offensive equipment was referred to as 'Frame' by civilians. The union of those two terms gave birth to the name 'Knightmare Frame'. This would become even more notable when the Knightmare Frame became the centerpiece of Knightmare Frame Duels which became ever more popular in the Underground Knight Games in the late twentieth century of the Imperial Calendar and into the Third Age of the Knightmare Frame.

Third Age: Archetype[]

With the results gained from the two separate programs, Knightmare Frames were developed in combat-effective platforms. Use of Sakuradite became paramount in making the Knightmare Frames perform to expectations, resulting in the mineral's value increasing greatly, turning it into a resource as important as fossil fuels in international politics. It would also see the start of the Knightmare Frame becoming quite notable in the Underground Knight Games, which pitted young wannabe Knights against one another in a series of events. Knightmare Frame battles then became ever more popular in these underground games with many teams constructing their own Knightmare Frames. This became ever more popular till the creation of an official leagues for Knightmare Frame Duels across Britannia, and even in some places of Europia. Unlike earlier Knightmare Frame Duels in the Underground Knight Games which had teams build their own hodgepodge Knightmare Frames these now official Knightmare Frame Duels would often have teams sponsored by either a large noble house or just a simple company who would built the required Knightmare Frame.

One such company would be the Ashford Foundation who had been reasonable for a few of the more major improvements in the previous age. The Foundation and its controlling Ashford Noble Family would introduce the brand-new Ganymede Knightmare Frame, one of the first true Third Age Knightmare Frames. The Ganymede and its more famous devicer Marianne "The Flash" Lamperouge would go on to become three time champion of the Knightmare Frame Duel League. Before the Ganymede and Marianne would be used by the Ashford Foundation to further develop the Knightmare Frame. This would include fitting a second Ganymede Unit with a new Yggdrasil Drive which would become standard for further knightmare frames which would become mainly introduced in the Fourth Age of the Knightmare Frame.

Overall, the Third Age of Knightmare are mostly known for their participation in that of the Underground Knight Games, and that of the official Knightmare Frame Duels. Thanks to this, unlike later ages which had several different mass produced models, the Third Age sport dozens of different types of Knightmare Frames all custom built. This would include, as mentioned, the Ganymede built by that of the Ashford Foundation, the Crossbow built by Savage Arms Corporation, the Shamrock built by Steiner Konzern, the Orlando built by the Royal Aeronautical Ordinance Company, and the Cornhall built by the Imperial Panzer Works. Overall, a grand total of thirty-three customized one-of-kind Knightmare Frames where created in the early years of the new Knightmare Frame Duel Association. It wasn't till the Ashford Foundation would introduce their KF7-A3/A Axion an improvement over their older Ganymede Knightmare Frame that would lead to a set standardized model for the Knightmare Frame Duels. However, the Ashford Foundation would only produce a couple dozen of these knightmares before the Foundation would fall in fame thanks in part to the assassination of Fifth Empress Marianne vi Britannia. Later the new Fourth Age Knightmare Frame RPD-10A Prytwen would be introduced by the Imperial Panzer Works based on their new military-rated RPI-11 Glasgow Knightmare Frames.

All in all, the Third Age of Knightmare Frames would introduce the concept of Knightmare Frame to the general public and would start Britannia's overall fascination for the new Knightmare Frame which would jumpstart the development of more military rated versions of the Knightmare Frame leading to the idea of a Knightmare Frame as a military weapon.

Fourth Age: Implementation[]

The Fourth Age saw the introduction of the RPI-11 Glasgow, the first overall mass-produced knightmare frame. Its abilities allowed the Britannian Empire to easily dominate Japan during the invasion of 2010 A.T.B. The Glasgow moved on to become the baseline unit for the Britannian Army, though it is eventually made obsolete a couple years later. Being pretty much replaced by the superior RPI-13 Sutherland by 2013 A.T.B. Some Glasgow units are still used by the Knight Police for law enforcement, and other countries have used it as a base by some smaller countries in the creation of their own Knightmare Frames like Japan's Type-1R Burai or the Middle East Federation's own Mark-3 Ifrit.

Other Fourth Age Knightmare Frames would include the KF7-A4/C Axion Lancer an improved and combat rated version of Ashford Foundation's earlier Knightmare Frame Axion who had developed it for the military contract for the first combat-rated military knightmare frame, and Europia's new Panzer Series of Knightmare Frames starting with the Panzer I which is said to be a borderline Third Age Knightmare Frame with only its inclusion of a Yggdrasil Drive making it a Fourth Age Knightmare Frame. Meanwhile, to continue the previous Age's Knightmare Frames use in Knightmare Frame Duels the Imperial Panzer Works would introduced their RPD-10A Prytwen the new standard Duelist Knightmare Frame for the Knightmare Frame Duel Association.

Overall, the Fourth Age would see the first true combat-rated Knightmare Frames with the introduction of the Glasgow and would also see the overall introduction of the new Yggdrasil Drive. It would also start to see the Knightmare Frame becoming the premier military weapon across the weapon. With many other nations across the planet starting their own development programs for Knightmare Frames, or even using another nation's Knightmare Frame as a basis for their own design.

Fifth Age: Evolution[]

Following the success of the Knightmare Frames against conventional weapons of war, attention was turned to creating Knightmare Frames intended to destroy similar weapons, including other Knightmare Frames. The RPI-13 Sutherland is the result of this. The Sutherland features improvements to cockpit comfort and function, better mobility, and increased close-combat capabilities to emphasize its role as an anti-Knightmare weapon. The Second Princess Cornelia and her bodyguards make use of the Gloucester, a Sutherland variant designed specifically to combat other Knightmare Frames, reflecting the Chinese Federation and the EU's development of their own Knightmare Frames.

Fifth Age, One Half: Development[]

The so-called Fifth Age, One Half or better known as Fifth Age Plus, is actually a series of improvements done to already existing Fifth Age Knightmare Frames using data and improvements from either the Sixth or Seventh Age Knightmare Frame prototypes. This would first be seen with the Sutherland Club which sported improvements from the Seventh Age Prototype Knightmare Frame Z-01 Lancelot. These improvements would include a new sixth generation Yggdrasil Drive, new software and upgrades for the cockpit, and finally the ability to use a Float System without the earlier troubles with the new system. This would lead to further upgrade programs for other Fifth Age Knightmare Frames including the RPI-209E Gloucester Full Production Type, or better known as the Gloucester Plus which includes all of the improvements from that of earlier introduced Sutherland Club but on a cheaper platform. The first full non-upgraded Knightmare Frame of this age would actually be the MBF-M11 Javelin introduced by Morgenroete Engineering for the new Kingdom of Orb. This could become a major development in Knightmare Frames after the end of the Second Black Rebellion and the end of the Second Great War as the Eighth Age Knightmare Frames as a whole were a bit to expensive in Sakuradite for full mass production for some of the powers around the world. This would include not only the newborn Kingdom of Orb, but the Holy Britannian Empire who would have lost the largest Sakuradite source to the newly formed United Federation of Nations. Hence, the need for such a catch up on older Knightmare Frames.

Sixth and Seventh Ages: Missing and Continuation[]

The sixth age features almost no improvements in Knightmare Frame technology, earning it the moniker "Missing Generation". Even then some of the Sixth Generation Knightmares end up becoming notable like the IFX-V3D1 Gawain and the Mk6-W0X Alexander. Both of which end up leading to the development of new technologies and new Knightmare Frames. The creation of the Seventh Generation Lancelot marked the first significant innovation. Sakuradite is not only used in the Yggdrasil Drive but is also scattered throughout the frame, increasing performance dramatically in all areas. This allows the Lancelot to effectively employ the MVS (Maser Vibration Sword) and electromagnetic shielding. In addition to the frame, Sakuradite is also used in the VARIS (Variable Ammunition Repulsion Impact Spitfire), with the intent of giving it the strength to survive a direct hit. This kind of rapid development completely defies the notion of general-purpose and mass production units, resulting in the Lancelot being a unique machine. Soon after the introduction of the Lancelot other Seventh Age Knightmares are developed like the Type-01 Guren Mark I and the Type-02 Guren Mark II. Then there are the handful of Lancelot variants including the Z-01/D Lancelot Conquista and Z-01/F Lancelot Frontier.

Seventh Age, One Half: Succession []

This 'age' continues the older Seventh Generation Knightmare Prototypes and basically evolve them into one-of-kind custom machines built for the use of a single pilot. Though the Knightmares built under this generation are often built from the ground-up for aerial combat with the needed upgrades in the cockpit and the option to mount a Float System, unlike the previous generation knightmares which had to be vastly upgraded. This is passed onto the new mass-produced eighth generation knightmare frames. This generation includes the various machines built for the Britannian Knights of the Rounds, the Black Knight Supreme Commander Zero, and some of his more experienced followers. This also means that these machines are not ever going to be used as a basis for Mass Production Models, and remain as One-Of-Kind Models. That said, unlike previous generations, these units are still quite superior over the following Eighth Generation mass-produced Knightmare models.

Eighth Age: Distribution[]

After the massive development of the various Sixth and Seventh Generation Prototypes, both the Empire and the Order of the Black Knights would develop the so-called Eighth-Age of Knightmares which sees the production of brand new mass-produced models for the common usage. These models usually have scaled-back tech that had been introduced in the various older Prototypes. These eighth-generation knightmares also sport a small limited amount of Sakuradite laced through its frame, something first pioneered by the Britannian Seventh Generation Knightmare Lancelot. Like the previous generation knightmare frames the eighth generation knightmares are built from the ground-up for aerial combat which includes the needed cockpit upgrades, including software, and the option to mount a Float System. During both the Second Black Rebellion, and the Third Great War the Knightmares of the Eighth Age would become the main Knightmare of choice for both the Empire, only recently, and the new United Federation of Nations along with the smaller nation of the Kingdom of Orb with their own recently introduced MBF-M12 Lancer.

Ninth Age: Aspirations[]

The Ninth Age sees the introduction of the Energy Wing, a Float System giving unrivaled agility and allowing for blinding speeds, and the slightly downgraded version known as the Wings of Light System but both are highly difficult to control. Not to mention expensive in not only Sakuradite but power which the downgraded Wings of Light System suffers from in its design which has lead to regular Knightmare Frames being known as pseudo-Ninth Age Knightmare Frames. Currently only two true Ninth Age Knightmares are currently known to exist: the Lancelot Albion and the Guren S.E.I.T.E.N. Eight Elements Type. The latter of which was purposefully downgraded back to a seventh age Knightmare Frame and the Energy Wing components passed over to that of the United Federation of Nations. Of which, has led to the development of the third true Ninth Generation the XT-410 Shen Hu Húdié. Currently, there are some plans to look into further applications of Ninth Age Knightmares which has lead to the development of the so-called "Wings of Light" Float System with both the Empire and the Black Knights, however, as state this system can only be used in short bursts and if a pilot is not careful can drain their energy filler entirely.
