One of the Bagua robots that appears in "Pluto Project Zeorymer." Named after "Heaven," the first of the eight trigrams (Heaven, Wind, Water, Fire, Moon, Earth, Mountain, and Thunder), it boasts overwhelming performance that surpasses all the others. Its main pilot is Akitsu Masato, and its sub-pilot is Himuro Miku.

Its greatest feature and the secret to its incredible power lies in the "Dimension Linkage System," a mechanism developed by its creator, Kihara Masaki, that collects energy from different dimensions and redirects it for attack. Its greatest weapon is the "Meiou Attack," which endlessly releases the energy collected by the Dimension Linkage System, powerful enough to annihilate an entire city. Due to its tremendous power, it normally forms an energy field that is concentrated and released at a single point. Conversely, if that power were ever directed at it, it is a double-edged sword, as it will mercilessly burn itself and its pilot to ashes, wiping them from the face of the earth.

Originally intended to be the pinnacle of the Bagua Robots and the core of the "Hades Project," it was removed from Tekkoryu by Masaki and taken into the hands of the Japanese government. Masaki defected from Tekkoryu and was killed by Oki Isao. The remaining Zeorymer was split into four parts—upper body, arms, and lower body—and preserved as research material. (There's even a scene where the parts combine in an elevator.)
