A new monster appears on Earth! Gonda (Umibozu), a creature that can change from normal size to giant instantaneously, attacks young people and destroys cars and trucks. However, this creature is not Rodak’s! Rodak orders his men to find out what Gonda is and who sent him. Both Rodak and Mathusam feel some kind of unusual energy from the Nastric galaxy. United Press International sends Kita to investigate Gonda. An elderly man named Kazuki (Harada) talks about his grandson, Taro, who was killed by a truck. Kazuki later tells his wife that he is happy that Gonda is destroying motor vehicles. Kita, Gam, and Mikko see Gonda smashing a car. Gam attacks the creature, but nothing happens. Goldar is called, but Gonda retreats. Goldar says that it is true that the monster is not one of Rodak’s, and that it has the heart and mind of a human.
