Grodd is coming! The popular Flash villain has made a few brief appearances throughout the first half of The Flash’s freshman season, but he’ll be coming out in full force soon.

As comic book fans know, Grodd is a hyper-intelligent telepathic gorilla whose eventual appearance was teased back in the show’s pilot, which included a shot of a his damaged and empty cage at S.T.A.R. Labs. Grodd, who was also revealed to be one of General Wiling’s (Clancy Brown) former test subjects, recently took down two maintenance workers in a sewer that had scribblings of his own name all over the walls.
