Koji shows Mazinger Z to a Photon Power Lab's guest, Dr. Gordon. He turns out to be a old friend of his late grandfather as well as brilliant scientist himself.

After learning about it from the news, Sayaka warns the others about all the shipwreckings happening on the pacific ocean. This revelation makes Dr. Gordon go pale: his wife and daughter are coming to the Photon Power Lab in a cruise. Just as he feared, the ship transporting his family gets sunk. Although Mary, Gordon's wife, drowns, their daughter manages to escapes in a lifeboat. Suspecting the shipwrecking was Hell's doing, Koji and Sayaka leave to investigate.

Just after rescuing an unconcious Lisa, Mazinger Z gets attacked by the one responsible for the shipwreckings: the Mechanical Beast Glossam X2. Glossam drags Mazinger Z underwater, but Koji manages to escape.
