Volvemon

The Digimon known as Volvemon came into existence back when the Digital World was still an experimental environment unmanaged by a central operating system. Having created the test space to observe digital lifeforms, researchers managed to simulate a survivable environment, but they were unable to induce any changes in primordial lifeforms that had been designed to be equivalent to present-day In-Training Ⅰ Digimon. That was when they introduced an environmental AI—what would later be called Volvemon—to cycle the world through stages. It would use the halo on its back to convert the digital environment to pure data and absorb it, then use the generator on its chest to compress the data for emanation, thereby perpetuating the world. Day and night, temperature and atmospheric pressure, tidal forces, the changing seasons, and even the three phases of water, all the world's cycles were thus established and sustained. Following Volvemon's introduction, the test space underwent diverse environmental cycles that stimulated the digital lifeforms to ultimately achieve the transformation known as Digivolution. The evolution of digital lifeforms ushered in an expansion of the experimental environment, causing it to eventually become the vast realm that is the Digital World. Because no combat test logs exist, this is purely conjecture, but the maelstrom generated by Volvemon's Revolutio Rerum—the process of absorbing all nearby matter for subsequent emanation—must certainly bring total annihilation to anything that gets caught up in it. Records indicate that after control over the Digital World was transferred to the central operating system, it became capable of functioning without Volvemon. No longer needed, Volvemon was sealed within the system as two separate entities—one possessing the power of absorption and the other of emanation.
