Gorilla City was the name of the Brain's headquarters in Bwunda. It consisted of a series of Quonset huts. It was destroyed after the Brain activated its self-destruct system.
The first Quonset hut was built in 2008 for use as a laboratory by a thin man and an old woman. There they enhanced the intellect of a captured gorilla named Mallah; inserted the woman's brain into the body of another gorilla, Tolifhar, to create the Ultra-Humanite; and inserted the man's brain into a mechanical construct to create the Brain. More huts were erected. The site was named Gorilla City, and from there a whole troop of gorillas was captured and enhanced.
The Brain, Ultra-Humanite and Monsieur Mallah saw the Team approaching through the jungle on a monitor in their headquarters. They sent Gorilla Grodd to capture them.

Grodd and his squad of gorillas brought most of the Team, unconscious and fitted with inhibitor collars, to the compound. The Brain and Ultra-Humanite were unhappy Miss Martian and Wolf had not been captured. They sent Grodd out to find them.
In one hut, Grodd, Solovar, Boka and Primat held a telepathic conference with Miss Martian. In the main hut, Brain and Ultra-Humanite discussed what to do with their new captives, who were shackled to a wall. Later, Miss Martian knocked out the guards to another hut, where the troop's children were being held hostage, and took the children to safety. In the main hut, Robin escaped, detonated a smoke grenade and freed his teammates. The Team and their gorilla allies defeated the Brain, Ultra-Humanite and Mallah, so the Brain activated the base's self-destruct on a five-minute timer. The base was evacuated before being destroyed in a series of explosions.
Later, when asked about his troop's future, Solovar suggested they might build a Gorilla City of their own.
