The Mazinger army was defeated by Dr. Hell when the Million Squad and Venus A decides to use Photonic beam attack to Dr. Hell. Unknown to them, the King of Hell has a Photon absorber that will absorb all kinds of photon attacks thereby giving it more photon energy power. The Photon fortress attacks and the King of Hell absorbed all the photon beam attacks. The Photon fortress is now being sucked into Dr. Hell. It was revealed that Kenzo realized his mistake when he saw the arm of Zeus. Kenzo has built the King of Hell for Dr. Hell to absorb photon energy. Realizing his mistake, he reprogrammed Gamia Q3 to reverse the polarity of photon where the photon energy will be drained from the King of Hell's body. Gamia Q3 went into the Photon Fortress to reverse the flow of photon energy. Suddenly, inside the King of Hell's body, Dr. Hell was surprised to see Kouji along with Baron Ashura.
