In the SOD Universe, there are multiple knightmare frames both mass produced for armies and custom made for the best pilots in the globe. Note that the frames are listed by who uses them and not who created them.
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 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.
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, are introduced, and by 2018 also fall into common use.
In 2018 an advanced float system known as the Energy Wing System was created, but restricted to ten 9th Generation knightmares per nation to reduce possibility of the blueprints of falling into terrorist hands.
