The Yaoguai (Mandarin for "Monster") is a knightmare frame produced and utilized by the Chinese Federation, namely the Chinese Liberation Army (CLA), as their mainstray forces in Code Geass Megiddo.


The Megiddo version of the Gun Ru. No design changes are made.


As the mainline knightmare of the Chinese Federation's Liberation Army, the Yaoguai was a true reflection of its home country at the time of its development. Built primarily for numbers, the Yaoguai lacks most of the refinements that one would associate with the knightmare frame in general, being larger than average (a consequence of Chinese technology level), comprised of cheap and mundane mechanics (which are infamously prone to breakdowns) and having relatively little regard for the survivability of the pilot. Its dome shaped design gives it a larger targeting profile than most knightmares, yet its armor is poorly resistant to modern weaponry. Its Yggdrasil drive is very underpowered, and its landspinners are only capable of propelling the knightmare forward or backward at lesser speeds. Though it is fairly armed, mounting a pair of machine guns and cannons, its weapons are completely fixed forward and in a narrow firing arc, meaning the Yaoguai must turn its entire torso in order to engage targets at its sides or behind. And finally, it lacks the ejectable cockpit that most knightmare frames take for granted, while the only access point is placed toward the front, leaving the pilot vulnerable to enemy fire upon abandoning the frame.

Due to these numerous "qualities", the Yaoguai is well regarded as a death trap among devicers everywhere. The Chinese refer to them as guancai (Mandarin for "coffins"), while the Britannians and Eurasians mockingly refer to them as "tadpoles" for their vaguely frog-like appearance in combination with their tail stabilizers.

Even so, in spite of common belief, the Yaoguai can be utilized as an effective weapon when deployed in large enough numbers, and the Chinese are well aware of this fact. For all of its flaws, the Yaoguai is easy to produce and maintain, while its control system is simple and easier to learn compared to most other knightmare types (a necessity for the heavily conscripted CLA), thereby ensuring the KMF's abundance, with the Chinese fielding twelve Yaoguai for every one Britannian Sutherland or Eurasian Ritter II. Due to these factors, as well as the dire state of Chinese technology level, the Yaoguai has remained in production longer than any other knightmare frame (much to the dismay of their pilots) and so remains the main strength of the Chinese Liberation Army.


Built in the same generation as the Glasgow and the Ritter, the Yaoguai would quickly become the Chinese Federation's weapon of choice. Though an incredibly flawed design, its ease of production would ensure its continued usage within the Chinese Liberation Army (much to the ire of Chinese commanders and pilots) even when later generation knightmares had been produced by Britannia and the EU.

One of the more infamous deployments of the Yaoguai was during Operation Hai Long Wang, the Chinese Federation's attempted false flag invasion of Kyushu, the southernmost island of Japan. The Yaoguai was utilized effectively in this operation, overwhelming the island's initial defenders and even managing to corner Suzaku Kururugi and his Lancelot with their sheer numbers. However, the surprise intervention of Black Knight leader Zero in the Gawain quickly turned the situation around, and the Yaoguai were wiped out to a frame not long after.

After the Chinese Federation was annexed into Britannia, the CLA would go underground to wage a rebellion against the Imperials and their collaborators, and so would continue utilizing the Yaoguai as their main weapon. By this time however, the Yaoguai would be well past its era, with the Britannians holding a large technological advantage over the CLA. Even so, having no other options beyond the Four Beasts, the advanced seventh generation knightmare frames utilized by General Li Xingke and his followers, the Tianshou, the Chinese would continue to make use of the Yaoguai throughout this seven-year war.
