For months, the threat of Grodd has loomed in the background of The CW's hit superhero series, and on tonight's episode of "The Flash," Det. Joe West comes face to face with the fearsome psychic simian.

In a new clip from the episode, aptly titled "Grodd," West finds himself cornered in the gorilla's sewers-based home, and attempts to reason with the not-yet-super-smart DC Comics icon, only to discover some of the super-ape's dislikes.

"Grodd" airs tonight at 8 p.m. on The Cw.
