Gun-Ru

In an attempt to match the effectiveness of Britannian Knightmare Frames, the Chinese Federation designed the Gun-Ru (鋼髏, lit. Steel Skeleton), a Knightmare both similar to and yet highly different from Britannian models. The Chinese Federation deployed many Gun-Ru's during its attempt to take over Kyushu, the southernmost island of Japan. Initially, even Suzaku Kururugi and his Lancelot were overwhelmed by the sheer number of Gun-Ru sent after him, but the surprise intervention of Black Knight leader Zero in the Gawain turns the tables on the Chinese.

A year later in the second season, it is still shown to be the main Knightmare Frame of the Chinese Federation. Once again, it is used in vast numbers, deployed by the hundreds in the battle between Zero and the Black Knights, and the Chinese Forces led by Li Xingke and the High Eunuchs; their large numbers had prove adept at breaking through formations. A few Gun-Ru were also deployed in the Kagoshima Settlement Battle.

Design and Specifications
Larger than its Britannian counterparts, the Gun-Ru's body is dome-shaped and painted green (though red-colored versions are seen in the second season) (it turns out that the red-colored Gun-Ru's are the ones that are loyal to the High Eunuchs, while the green-colored versions are loyal to Li Xingke) with smaller legs and manipulators that fold into the body, giving it an almost frog-like appearance. The Gun-Ru's armament consists of a pair of machine guns and a pair of cannons, mounted on the shoulders of the main unit. Unlike other Knightmare Frames it does not feature a cockpit ejection system, requiring entry and exit from the front. Though much weaker than Britannian Knightmares, the Gun-Ru's are cheaper to produce, allowing the Chinese to rely upon the strength of numbers when using them.

Trivia

 * On Code Geass: Kiseki's Birthday, it is shown that the Gun-Ru can be disabled with superglue if it is applied in the ignition key.
