The Flash Season 2: 28 Easter Eggs & References You Might've Missed
21. Gorilla City
Oh. My. Grodd!
One of the highlights of Season 1, Gorilla Grodd made his return early in Season 2 with the episode Gorilla Warfare. It maybe wasn't quite as spectacular as his previous outing, but the sheer fact that they can even pull off a giant psychic gorilla is impressive enough.
At the end of the episode, Grodd is shipped off to Earth-2, to be with his own kind. The place he's sent to is Gorilla City - home for super-intelligent gorillas like himself. In the comics, Barry is the first person on Earth to encounter the city, and while Grodd is often trying to take over it, ruler King Solovar is an ally of the Flash.
