Zandor rescues a young boy from a vulture; the Herculoids then take the boy back to his heavily-shadowed home because he can not live in sunlight. The insect-looking creatures attack the Herculoids on their way out.

Zandor briefly frees Dorno with his shield but is soon captured with Dorno. After a stalemate, Zandor calls the Herculoids to action for one concentrated attack.

Zandor was captured by Gorvac, leader of the Android People, and created a giant evil clone of Zandor with plans to create an army of Zandor clones.
