Grodd, also known as Gorilla Grodd, is a hyper-intelligent ape, native to Gorilla City.
Grodd was a scientist in Gorilla City. He developed a helmet that allowed him to control the minds of others. The Gorilla City security force stopped him from using it in the city, but he escaped capture and eventually wound up in Central City, where he ran afoul of The Flash and Green Lantern. Grodd was seemingly rendered harmless after Flash "crossed a few wires" in his mind control helmet and tricked him into using it. The monkey, however, not only recovered from this, but no longer needed the helmet to control minds.
At some point, Grodd met a female gorilla named Giganta, who he trasformed into a human, who could grow to many times her normal size. It is unknown if she always had this ability or if it was as a result of Grodd's work.
Grodd and Giganta would later recruit Shade, Parasite, Sinistro, Killer Frost, and Clayface into the first Secret Society. They attacked, and nearly destroyed the Justice League, but were defeated in the end.
Grodd then put together a second Secret Society, organizing nearly every supervillian on Earth into one group. He was overthrown as leader of the Society by Lex Luthor, and was later blown out of an airlock in deep space after failing to depose Luthor. It is probable that Grodd was killed, but as he tumbled into space, Grodd swore to Luthor that he would find a way to survive and take his revenge.
As a gorilla, Grodd possessed strength and stamina much greater than that of even the strongest normal human being. In addition, he possessed a hyper-developed brain, and was one of the most intelligent beings on Earth. His advanced brain developed incredible mental powers (with some accidental help from The Flash's tinkering), most notably mind control and telepathy. With these abilities he could manipulate a person's movements or simply terrorize them into helplessness.
