Armored Geass: Project Requiem/Mecha

Knightmare Frame is a mechanical, often humanoid war machines, suit that makes extensive use of Metatron-based technology. Kinghtmare Frames were developed and are most often used by the Holy Britannian Empire, who use it to the extent such that most people who encounter Knightmare Frames in general believe one to be owned by the organization. Unveiled during the invasion of Japan, Knightmare Frames are almost exclusively used in place, and sometimes on par with the practically obsolete main battle tanks. The name "Knightmare Frame" is a play on the word nightmare and a knight's mare. There also exists a derivative type of war machine based on the Knightmare Frames called Knight Giga Fortress.

Overview
Like the original counterpart, Knightmare Frames often have a humanoid shape and are usually between four and five meters tall, about twice the height of an average main battle tank, giving them a significant height advantage, although unnecessarily range advantage. 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 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 'hump back' in the unit. The cockpit is a self-contained control center which can be ejected in case of emergency. Although Knightmare heads seem to have no real function besides housing Factsphere sensors, it seems they are required to pilot the Knightmare, as seen when a pilot ejects himself when his life in danger and the Knightmare's head is knocked off.

Knightmare Frames are typically armed with rocket-propelled anchors called Slash Harkens (スラッシュハーケン,Surasshuhāken) and a number of other weapons. Mass-production models usually carry handheld rifles, which are able to fire micro ordinance as well, 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 rate to cut through almost anything, and Hadron Cannons, powerful energy cannons which can obliterate almost anything in their path. Late in 2017, Float Systems (フロートシステム, Furōto Shisutemu), devices which allow Knighmares to fly, are introduced.

Unlike this canon, Knightmare Frame doesn't meant to retire or collapse when Britannia's plans ongoing, not only than Knightmare Frames, even the other Knightmare Frame known as NEXT or Advance Knightmare Frame.

Normal
Normal KFs, usually shortened to Normals, are in essence the first generation of Knightmare Frames within the Armored Geass Universe. Unlike in earlier Code Geass anime, Normals are relatively low cost, mass produced, and non-customizable mechanized units, similar to Wanzer from Front Mission. They are used as the primary ground forces of the companies, usually deployed with conventional units and saw widespread use in the National Conquestion War.

Normals do not use Kojima Particles. They have been shown in battle to be ineffective against NEXTs unless deployed in massive numbers, and even then are still ineffective against skilled Lynx.

Original
An Original is a LYNX who has been piloting NEXTs since the time of the National Conquestion War - the time of the creation of the 'original' NEXT technology.

Originals consider themselves to be the 'chosen' few; only 26 pilots are classed as Originals. They are ranked from 1 through 26 in the order of their accomplishments on the battlefield. Most of the Originals were killed during the Lynx War, either in conflict with one another, or at the hands of the new generation of Lynx (such as Rai).
