Revenge on Gorilla City

After an attempt with a Hallucinogenic vapor that makes fears appear to take over Gorilla City, Grodd is detained and teleported back to the Legion of Doom by the city's ruler, Solovar. 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. They get through the invisible force field and connect the device on the telpathic communicators. Solovar, the ruler of Gorilla City, teleports away and convinces Flash, Apache Chief, Batman and Robin to help him free the minds of the Gorillas. The four heroes get caught by Black Manta's ray taking away their powers and must escape being hunted, call for help, and free the Gorillas from the mind control with Solovar's help. With the Super Friends and the Gorillas after them, the Legion retreats from Gorilla City.
