Goldar arrives and attacks Nardo! As the two titans fight, Rodak’s ship appears overhead and Rodak announces that Nardo will keep Goldar busy while the insects do their job. Nardo eventually retreats and the boys inform the authorities what has happened. The radar units scan for the bugs, with no luck. American scientist Dr. Reed is coming from New York with a plan to stop the bugs by using shock waves. Using a hidden transmitter, Rodak learns of the arrival of the doctor and his plan. Tom Mura goes to the pier to greet Dr. Reed who is arriving by boat. Rodak sends Nardo to destroy the ship. However, Dr. Reed is actually travelling by submarine, ruining Rodak’s plan. Silvar is sent by Mathusam to find out where the insects are and what sustains them on Earth. She discovers a plant (Nesugiras) that gives the insects their energy. Moving closer, the plants come alive, catching her. Goldar rescues Silvar, but finds out that his ray does not damage the plants.
