Grodd

Origin: Gorilla Grodd is a member of the hidden Gorilla City in Africa. They are a society of super evolved Gorillas who are as intelligent if not moreso than humans. Grodd was a criminal of Gorilla City, and he blames the city and it's inhabitants. He's desire is to destory Gorilla City and with his mind control helmet and technology, he certainly has the power to do so.

Comments: In the comics, Grodd has primarily been a Flash villian. As the end to The Brave and the Bold indicates, we likely have not seen the end of Grodd, and there have been rumors that he will return in the second season.

It is unknown what role Sarah Corwin, the doctor who is in love with Grodd, plays, and if she will return.
