A tough new deputy will come to town when Season 4 of NBC's "Grimm" kicks off next month.

According to TVLine, "Franklin & Bash" star Toni Trucks will play Deputy Janelle Farris, a strong county lawwoman who seeks Nick and Hank's help in order to solve a highway-crime scene that seems a bit strange.

The "Grimm" official Twitter account also hinted that Farris "finds herself pushing her resilience to the limit."

The "Hostages" actress will make her debut on the show during Episode 6 of the upcoming season.

In addition, "Warehouse 13" actor Erick Avari will guest star as a salvage-yard owner. His business will grab Nick's attention in regard to several highway disappearances.

Last week, NBC unveiled details and photos about the new Wesen Nick and Hank will face when the Season 4 kicks off next month, reports Entertainment Weekly.

Gedächtnis Esser, or Octo-man, is an evil Wesen who "steals your identity but in a very disgusting way," reports the Los Angeles Times' Hero Complex. The Wesen, which is part-man and part-octopus, attaches its tentacles to someone's head in order to steal their memories and leave them with dementia.

"A lot of what we do is try to explain real-world problems, like in this case, identity theft," Kouf told EW. "Our best Wesen ideas come when we have an emotional core that explains something in life."

The Schinderdiv is a demonic beast that represents "people who are only out for themselves and do anything to achieve a goal," teased executive producer David Greenwalt. In a photo, the ruthlessness and selfishness Wesen appears to have long-bottom fangs.

In the meantime, the Heftigauroch is a bull-like Wesen that morphs into rage when provoked. On the show, he's a peaceful boxer who does not like to fight who transforms into a raging bull once provoked. "When a bull is brought into a ring it doesn't necessarily want a fight, it requires being hit with picadors to get mad - this Wesen requires the same treatment," Kouf says.

And lastly, the EP described the Golem as a 10-foot Wesen made of clay that was made to protect the meek but is dangerous to try to control. "The twist with our Golem is how it gets destroyed," Kouf said.

Season 4 of "Grimm" premieres on NBC on Friday, Oct. 24 at 9 p.m. ET.
