History
Project Phoenix King, a highly, advanced weapons program of the Katsuragi Protectorate that had been in development outside of their conventional Katsuragi Protectorate Self-Defense Force arsenal since the Great Voshkod-Aquilan War and the Sundering of 1979 V.C.. The Voshkod was taken especially by surprise, as her borders were among the first to be darkened by the Protectorate's shadow.

When the Protectorate finally revealed its Project Phoenix King high-tech weapons, many top military aides in the Voshkod quickly resigned in embarrassment, while others were incarcerated (or worse) for failing to gather sufficient data on their new enemies. Some maintain that reasonable human error caused the Destroyers' greatest military minds to fail to detect the development of Protectorate's advanced weaponry purely designed for an ambush.

However, there was absolutely no satisfying explanation for how a monstrosity outside of the Yonmaru, the standard SDF equivalent, such as the King Oni could have been overlooked by the global intelligence community's top aides and agents until this massive battle-walker was already being put to use on the front lines alongside the KPSDF standard Yonmaru, the Protectorate's actual counter to Apocalypse tank. How could such a preposterous weapon, which flies in the face of decades of conventional KPSDF mechanized warfare, have been developed purely in isolation without anyone noticing?

The explanation that makes any sense is they are part of the Katsuragi Protectorate's Project Phoenix King, an weapons programs that was created following in the infamous Sundering of 1979 V.C. and that the world leaders were so embroiled in their own conflict that they became oblivious to the storm brewing in Ulthuan; a storm best characterized by the unbelievable visage of the King Oni.

It remains unknown why the Katsuragi military was compelled to design such an unorthodox fighting machine as this humanoid-shaped construct, which stands approximately six stories tall and evokes images of a mechanical, hulking ogre. However, battlefield performance reports of this vehicle are very sobering and suggest that its bizarre form factor is not merely a play against enemy morale. Indeed, the King Oni's combat capabilities alone are more than enough to dampen an opposing army's spirits. Its giant fists delivering devastating blows that can crush anything that gets in the way, while its "eyes" conceal energy weapons that can reduce a tank to molten ruin in seconds, though they are used sparingly to strike down armor from range. After all, the warrior is the weapon; his eyeblasters are merely his allies.

Also, the King Oni is remarkably capable of fighting with its own body, using its massive arms and legs to crush anything that stands in its way. An early battlefield report involving the King Oni suggested that just one of these robots, when faced with an entire tank platoon, simply charged the main battle tanks head-on. Their shots deflected off of the King Oni's white armor (which must be some sort of new compound), even as it barrelled into the tanks, simply crushing them underfoot as though they were children's playthings.

Until recently it was not even known if the King Oni was piloted, remote-controlled, or autonomous vehicle. Still, the only thing that is certain about the King Oni is its combat proficiency. Military strategists surmise that it is almost impossible for the Protectorate to have constructed more than a handful of these remarkable machines. However, their credibility these days seems to be somewhat dubious.
