The Guren Mk-II (紅蓮弐式, Guren Nishiki?, lit. Crimson Lotus Type-02) is a unique Knightmare Frame model designed by Indian engineer Rakshata Chawla, manufactured by Japan, and built by the Kyōto House. In keeping with its name, the Guren's armor is predominantly red. It is radically different from its Britannian counterparts, and its technology is on par with seventh generation Knightmare Frames, such as the Lancelot. The Guren Mk-II's speed and strength can easily match the Lancelot's, but its lack of long-range weapons relegate it to a defensive close-combat role. Unlike Britannian-made Knightmare cockpits, the Guren Mk-II features an unconventional pilot seat, shaped like a motorbike, and a helm-like outgrowth surrounding its retractable head. Its Landspinners fold out from within its legs instead of being attached to the ankle. It is given to the Order of the Black Knights and piloted by Kallen Stadtfeld.
The Guren Mk-II's main weapon is its right arm. The arm is silver from the elbow down, and terminates in clawed fingers. Stored within the palm is the radiant wave surger (輻射波動, fukushahadō?, lit. radiation surge), a powerful microwave radiation emitter. By grabbing onto an enemy Knightmare and activating the emitter, the Guren Mk-II can fry the enemy's electronics and warp the frame itself, causing it to explode after a brief pause. The warping effect can also fuse the cockpit to the frame, preventing ejection. The arm can unhinge at the elbow to extend the Guren's reach. While not designed as such, the radiant wave surger can also function as a shield capable of blocking almost any attack, only failing against the Lancelot Conquista's Hadron Blaster. The arm is destroyed in the first season by Suzaku Kururugi, but is replaced in the second season with a slimmer, three-fingered version. The Guren Mk-II also possesses a fork-shaped knife, a grenade launcher on its left arm, and a single Slash Harken.
