When "Grimm" returns with its second season on Monday, August 13 at 8 P.M., Nick will first face off Mauvais Dentes. The first look at the beastly creature has made its way out via Entertainment Weekly, featuring the villain showing his saber teeth and vicious look.

Executive producer David Greenwalt gushes that the monster, which will appear in the second season premiere, is one of Nick's greatest foes yet. "He's the worst thing that's ever come; he can kill a whole village," he adds. "And he acts like a cat, so he likes to rope you in and play with you a little bit and observe you. He'll never be predictable."

As for the second season in general, executive producer Jim Kouf explains, "It's more focused on Nick now. Before, it was catch what [monsters] came across his desk. These are more directed toward him." He continues sharing, "There are forces at play who would like to see Nick proven to be an uber-Grimm - or dead."

A clip from the upcoming episode recently was released, giving a look at Nick introducing his mother to his friends Monroe and Rosalee. Rosalee later explains to Nick what happens to Juliette and what they need to do to save her.
