Deep in the heart of Africa is a city hidden by mountains and illusion. Where it now stands, a meteor (or a spacecraft, depending on which account you read) crashed during the 19th century, its rays imbuing a gorilla tribe with hyper-intelligence and telepathy. There they now live, in an advanced society using science far beyond our own.

On an exploratory mission, their leader Solovar was captured by humans. Rather than reveal the existence of Gorilla City, he played dumb and allowed himself to be taken to a Central City circus. Grodd came after him, but not for rescue; his intent was to steal Solovar’s secret for controlling others through force of mind. He succeeded, but ran afoul of the Flash for the first time. His plan to create an army of his fellow gorillas and take over the world was foiled.

Since then, Grodd has spent most of his time imprisoned in Gorilla City, breaking out only when he has a plan ready. Often he has gone to Central City, hoping to eliminate the Flash before he could interfere with his plans. At times, he has led a political faction within Gorilla City, sometimes even becoming the dominant force.

One of Grodd’s widest-ranging schemes was to arrange Solovar’s assassination and manipulate Gorilla City into war against humanity. In the course of this, Grodd absorbed too much neural energy from his fellow apes, leaving him with the intelligence of a normal ape (Martian Manhunter Annual #2, 1999). He has since recovered, and a failed attempt to set up a base in Florida led to his capture and incarceration in Iron Heights. Despite recovering his intelligence and force of mind, Grodd has become more savage with each attack.
