Revenge On Gorilla City

Back at a general meeting in the Legion of Doom's HQ, Grodd decides he would like to use Brainiac's brain wave amplifier to take over Gorilla City. Lex Luthor cites that Grodd's plan (turning everyone in Gorilla City into mind controlled apes) might work since everything else they tried has failed. Solovar, the ruler of Gorilla City, convinces Flash, Apache Chief, Batman and Robin to help him free the minds of the Gorillas. The four heroes get caught and must escape being hunted, call for help, and free the Gorillas from the mind control. With the Super Friends and the Gorillas after them, the Legion retreats from Gorilla City.
