Nothing says "Comics!" like a telepathic, super-intelligent gorilla in a purple cape. Honestly, if you need more than that to understand what makes Grodd such an amazing villain, I don't know what to do for you. But more than just representing another perfectly executed, yet simple concept for a Flash villain, Grodd has strong ties to Flash's mythos. Hailing from Gorilla City, a hidden society of highly evolved apes with ties to the Speed Force, Grodd has tried time and time again to infiltrate and conquer man's world, butting heads not just with numerous Flashes, but the Justice League, Wonder Woman, and the rest of the cream of DC's super-hero crop. Most recently, Grodd appeared in the New 52 largely intact, though with his powers boosted by the speed force.

Will such an outlandish character appear in the TV series? You might be surprised...
