Goldar is assigned to New York to help against an attack from Rodak. Rodak sends his newest creature Gorda (Teravarden) to spread the Zana chemical into all the Earth’s water supplies, causing everyone who drinks it to come under Rodak’s control. The monster’s underground movements also cause volcanoes to erupt. Rodak orders his men to have as many people as possible drink Zana so that he can have an army of spies. Many drink the water and become Rodak’s willing slaves. Rodak orders all the missing guests to return to their hotels and await further orders. Gam, Mikko and Kita go to the hotel to investigate and come face to face with Gorda. Kita is captured by Rodak’s men. Rodak orders Gorda to create more volcanic eruptions. Goldar returns from America and is told by Mathusam that Gorda is responsible for the Zana and must be destroyed.
