The RZX-8SR Safir is the chosen knightmare frame of Nena Gurlukovich, the Holy Britannian Empire's Knight of Eight in Code Geass Megiddo.


Inspired by the OZ-13MS Gundam Epyon from Mobile Suit Gundam Wing, but as a Knightmare Frame. It has noticeably sharp and ridged armor, giving it a demonic profile, while a pair of short wings (similar to the Okinawa ver. Altron Gundam's) are placed on its back on either side of the cockpit pod. It is armed with an ornate, elaborate scythe that is based on Marluxia's Fickle Erica from Kingdom Hearts 358/2 Days, but colored to match the rest of the frame. Slash harkens are mounted on its forearms, with Blaze Luminous generators further back. Colors are dark red and black with grey highlights.


Designed at the auspices of Nena Gurlukovich, the eccentric Knight of Eight, the Safir is one of the more unorthodox designs to be produced by Britannia, even for a Knight of the Round. Like most Round units, the Safir was designed around close-combat capability, and as such possesses far greater speed and mobility than average (which are further emphasized by its somewhat lighter weight), while its light but durable armor provides it a fair amount of protection. Alongside, it features the advanced electronics and mechanical systems of its generation, by themselves granting the Safir performance above and beyond those of most knightmare types.

However, what truly sets the Safir apart, even from its brethren within the Rounds, is that it only holds a very unique type of weapon: a large, ornate Maser Vibration Scythe. Though forwardly looking underequipped, as its only other weapons are a pair of forearm mounted slash harkens, this scythe is actually all that the Safir and its devicer require to fight. As Nena's fighting style is set around executing a series of dance-like maneuvers, namely those involving spins, twirls and other elaborate movements, the scythe is the perfect weapons to utilize, as its fluidness, reach and versatility allow the Safir to engage its foes from multiple angles, in both offensive and defensive advances. Alongside, the Safir's combat computer has been programmed with a series of combat techniques (or "dance steps" as Nena calls them) in order to bring out the weapon and its host knightmare's full potential.

Beyond those, the Safir's only other defining point is its demonic profile. As Nena specifically requested for her stede to be fashioned around a "true nightmare", the Safir holds notably ridged, scale-like armor and draconic texture. This, combined with the Safir's elegant yet deadly performance in battle alongside the knowledge that it is piloted by the Knight of Eight, has instilled terror into more than one enemy pilot.


  • SCW650 Maser Vibration Scythe
The Safir's primary weapon. Essentially a polearm with a large, angular blade, the scythe functions by channeling extremely high oscillation through said blade, giving them the famously high cutting powers of their weapon type while retaining unconventional fluidity and reach. Through the former, Nena can engage a series of dance-like maneuvers, through which the scythe can be used offensively and defensively, from cutting into enemy units to "swatting" bullets and missiles from the air. For greater efficiency, Nena has programmed the Safir's combat computer (which can directly control and maneuver the scythe) with several of her "dance steps", such that the computer can guide the scythe along accordingly as Nena executes one of these maneuvers. And finally, the scythe is equipped with a built-in thruster within its "head", allowing for augmented speed attacks as well.
  • ESH500 Slash Harken
The Slash Harken is the signature weapon of the Knightmare Frame, and is used by almost all KMF models. Slash Harkens are wire-guided projectiles with some form of anchor-like blunt object at its tip. They can be used in multiple ways varying from offensive to defensive, or as a means of transportation via anchoring them in an object, and retracting the cable. The Safir's harkens, mounted on the knightmare's forearms, are larger models meant as backup weapons and utility units, while also retaining the generators for its Blaze Luminous shields.

System FeaturesEdit

  • FSC8X Dual Factsphere Open Sensor Camera
As with most Britannian knightmares, the Safir has a pair of miniature factsphere sensor cameras mounted within its shoulders. The factsphere is essentially an advanced camera that relays live thermographic images and data to the pilot. Due to its sensitivity, both due to its intended purpose and to physical damage, the factsphere is usually kept behind a set of armored plates and only deployed for in-depth scans of a targeted item or area. As the Safir carries two units, it can literally scan at double the depth and range of a standard factsphere.
  • EDC8X Dual-Eye Sensor Camera
As traditional with most later generation knightmares, the Safir is equipped with a dual-eye sensor camera system, taking the form of a pair of human-like emerald "eyes" within its head. These cameras are decidedly more advanced than quad cameras equipped on preceding fourth and fifth generation knightmares, and were capable of visualizing the Safir surrounding to the best amount of detail and focus.
  • ECR8X Multispectral Sensor System
The Safir carries a standard sensor package, not unlike those of most knightmares. One small deviation, however, is that the Caius' sensors are designed to be rugged and highly durable, such that they may still function even after a direct hit from enemy weaponry.
  • LSP8X Landspinner Propulsion System
Designed from the beginning for high mobility, the Safir is equipped with higher grade landspinners, which are designed to produce much greater revolutions than standard units as well as holding reinforced tires for increased durability, especially against rougher terrain.
  • EVB8X "Blaze Luminous" MSV Particle Shield System
Based on data obtained from the original Z-01 Lancelot, the Safir is equipped with a standard Blaze Luminous system. Mounted in the Safir's arms in similar arrangement to the Lancelot, the Blaze Luminous provide the Safir a secondary defense against enemy weapons and attacks, notably energy weapons such as hadron cannons, radiant wave surgers or blitz weaponry. Otherwise they hold no defining function beyond the standards of its type.


Created for Nena Gurlukovich, Knight of Five and aptly titled "Reaper of Britannia", the RZX-8SR Safir would make its debut during the Great World War. Notably it would see service on the Western European Front, in which Nena took a direct role in the invasion of Spain and France, and later on in Area 22 (China), where he would fight against the Chinese Liberation Army (namely against General Li Xingke himself and his Tianshou Team) alongside the newly returned Black Knights.
