Summary
Dr. Hell shows Baron Ashura his newest Mechanical Beast, Deimos F3. It has the ability to split itself apart and come back together at the touch of a button. The doctor wants Ashura to sneak Deimos F3 into the Photon Power Lab and have it reassembled there.

At the lab, Dr. Yumi leaves the Three Scientists in charge as he goes to attend a conference in New York. Later that the day, the three decide to go bowling. Sayaka scolds them for leaving the lab unguarded, but Koji offers to stay there so they can go have fun.

The three scientists end up getting kidnapped. Baron Ashura brainwashes them into believing they are his servants. After returning to the lab, they place Mazinger Z outside.

The next day, Ashura shoots Deimos F3's disassembled parts at Mt. Fuji. This causes tremors that are felt by Koji and the others. They go investigate and end up being attacked when Deimos F3 reforms. The three scientists guide the Mechanical Beast to the lab. Koji rushes back home to get the Hover Pilder while Deimos F3 attacks a inactive Mazinger Z. Sayaka sorties in Aphrodite A to fight the Mechanical Beast.

Koji gets attacked by Iron Masks, but Boss and his gang save him. They stay behind to fight the Iron Masks while Koji rushes to Mazinger Z.

Aphrodite A gets defeated, Shiro knocks out the three scientists and Koji arrives in time to save everyone. After the Mechanical Beast is destroyed, Nossori, Morimori and Sewachi are confronted about what happened but don't seem to remember anything. Koji deduces they were brainwashed and asks them to fix the damaged pilder.
