A psychic gorilla taking on the Fastest Man Alive may sound ridiculous on paper, but Grodd has shown himself to be a very real threat to Central City on a number of occasions now. Recently he's invaded Barry Allen's home with a whole army of gorillas, and he was a significant enough threat that The Rogues were willing to put their differences with The Flash aside in order to team up and attempt to stop the villain. Making him even more frightening is the fact that Grodd recently managed to tap into the Speed Force, and he's now just as fast as the Scarlet Speedster. Psychic, fast, and super strong? Grodd is truly a force to be reckoned with.
