Summary
At the Photon Power Laboratory, Sayaka is testing Aphrodite A. Dr. Yumi is informed that missiles have been installed on the robot so she will be able to better defend herself when attacked by Mechanical Beasts.

Meanwhile, Koji is introduced as a new student in Boss and his gang's school. Boss challenges Koji to a motocycle contest. The entire class goes outside to watch their competition which Koji ends up winning.

Sayaka goes to the school to see Koji. Aphrodite A then goes out of control and runs away. Boss and Koji go after her. Turns out Mechanical Beast Gaia Q5 is using elotromagnetic waves to disrupt the robot's controls.

Koji brings Mazinger Z to defeat Gaia Q5. After being hit, Koji is unable to properly control Mazinger Z. Baron Ashura sends several Iron Masks to invade the Photon Power Lab. Boss takes Shiro to Mazinger Z after Dr. Yumi gives the boy a anti-eletromagnetic staff to nullify the Mechanical Beast's powers.

With help from his brother, Koji is able to regain control. Mazinger Z defeats Gaia Q5 and Aphrodite A succeds in fending off the iron Masks' attack to the lab.
