When Gamu Takayama was proceding in a virtual reality experiment, to discover the will of the Earth, he briefly encountered the mysterious glowing red giant, Ultraman Gaia, at the end of a tunnel of light. He witnessed a fierce battle between Gaia and the snake-like Dragon, inside what appeared to be the center of the Earth itself. Gaia eventually used his finishing move, the Photon Edge, completely obliterating the Vision Dragon before making contact with Gamu.
- Many publications listed the Vision Dragon's subtitle as Underground Dragon.
