Here’s a list of characters on the show Grimm, along with some information on each one.

Main Characters

Nick Burkhardt

Nicholas Burkhardt, played by David Giuntoli, is the show’s protagonist and titular Grimm. Nick is a homicide detective who discovers he is descended from a line of Grimms, hunters who fight supernatural forces. Even before his abilities manifested, Nick had an exceptional ability to make quick and accurate deductions about the motivations and pasts of individuals, which has now expressed itself as his ability to perceive the supernatural that nobody else can see. Nick had wanted to propose to his girlfriend, Juliette, for a while, although he felt that he would have to tell her about his life as a Grimm beforehand. Throughout the first season, Nick struggles to maintain balance with his normal life and his Grimm life, both tending to cross when he works cases that involve Wesen, the creatures of the Grimm world. As Nick dives deeper into his Grimm heritage, he begins to train with Monroe to use the weapons that his aunt Marie left behind, as well as increase his knowledge of the Wesen that are present in Portland. As of episode 19, Nick has successfully killed three Reapers, creatures sent out to kill Grimms (hence the Grimm Reaper title). He killed the first in defense of Marie, and the other two were killed in self-defense when they were sent to kill him by his lead suspect in a case. The latter two had their heads cut off and sent back home (with a note saying to send the best next time). In the season finale, Nick’s worries about the scratch Juliette received from Adalind’s cat forced him to reveal his Grimm heritage to her, causing Juliette to believe he has gone crazy. When bringing her to the trailer was not enough to convince her, they go to Monroe’s house so that Nick can show her his Blutbad form, though before Monroe could show her, Juliette collapsed and was brought to the hospital. Rosalee discovers that Juliette is going through memory loss, and when Juliette wakes up it is revealed that the only thing she has forgotten is Nick. Nick, after believing for eighteen years that both of his parents died in a car crash, discovers in the first episode of season two that his mother is alive and well, but he is still unaware of her true motives and full agenda.

Hank Griffin

Hank Griffin, played by Russell Hornsby, is Nick’s homicide partner who, like Juliette, was not aware that Nick is a Grimm until recently. He is somewhat sarcastic at times, and has gone through at least four marriages by the time the series begins, but is nevertheless still Nick’s best friend in the human world. Throughout the season, Hank starts to notice the strange occurrences that have been happening in Portland, and even in some of the cases he works on them with Nick. He was even used by Adalind to get closer to Nick, by consuming a “love sick” potion that caused him to develop obsessive behavior towards her. In episode 21 (Season 1, Episode 21), he accidentally runs into a transformed Monroe, who was leading search dogs away from his friend. Combined with seeing their dead suspect change back into human form from an experimental drug, Hank begins to have nightmares and heightened paranoia when he is home, and is even seen falling asleep with a fire arm. In episode 25 (Season 2, Episode 3) in “Bad Moon Rising“, Hank starts to doubt whether he can continue police work given his state of mind. When searching for the missing daughter of an old friend from high school, Hank learns his old friend is a Coyotl and Nick is a Grimm. After all is said and done, Hank tells Nick that he is comfortable now knowing the truth, reflecting that, while he may be crazy, at least there is someone else who is crazy too.

Juliette Silverton

Juliette Silverton, played by Bitsie Tulloch, is Nick’s girlfriend, a veterinarian. She spent much of her childhood in Spain with her grandmother, and as a result is fluent in Castilian Spanish. She is currently unaware of Nick’s duties as a Grimm. Although Marie suggested that Nick should leave Juliette for her safety, Nick has decided to stay with her. He postponed his original plans to propose to her while he explores his new life as a Grimm. However, in episode 16 (Season 1, Episode 16), Nick decided to propose to Juliette, only for her to turn him down due to her feeling as though he is hiding something from her. In episode 22 (Season 1, Episode 22), Juliette suffers a scratch while treating Adalind Schade’s cat. When Nick reacts with horror, Juliette demands he tell her what’s going on. Nick tries to explain by bring her to the trailer and then to Monroe, but Juliette falls unconscious and is taken to the hospital where she awakens with black eyes, her fate uncertain. She eventually awakens from her coma with a little help from a liquid made by Rosalee used as eye drops (made to try to stop any progressing memory loss, but not to actually wake her). Unfortunately due to a spell, while she remembers everything else about her life, all memories of Nick have been erased. She has also begun to develop an unusual attraction to Captain Renard due to his role in awakening her, but is fighting this attraction due to her complicated relationship with Nick.

Monroe

Monroe, played by Silas Weir Mitchell, is a Wider Blutbad who aids Nick with his cases. He is also a good friend of Nick’s, even though he has some issues with Grimms since a Grimm killed his grandfather (although he acknowledges that the ancestor deserved it for butchering a village). Monroe at first did not know that there were any more Grimms left until he meets Nick. In the first season Monroe is attacked by the Reapers for assisting Nick in his cases. Nick tells Monroe that he won’t ask for his help any more, but Monroe resolves to still help Nick, stating that he enjoys helping Nick disrupt the ‘status quo’ despite his occasional dissatisfaction with the demands Nick places on him. Monroe is knowledgeable about the supernatural creatures that Nick goes up against, serving as Nick’s direct source of insight and information into the supernatural community whenever the second-hand knowledge that Nick acquires from his ancestors’ books is inadequate, as well as assisting Nick when cases require Nick to rely on someone who knows about the threats he faces. He also helps Nick make contact with creatures that would avoid Nick due to his status as a Grimm. In episode 21 (Season 1, Episode 21), when Monroe’s friend was injured and suffering from the side effects of an experimental drug, he takes his friend’s jacket and make the search dogs chase him. While being chased in the forest, he is surrounded by the search dogs and transforms into his Blutbad form to scare them off, but runs into Hank when he heads back to his house. Because he “allowed” his changed form to be seen by normal beings, Hank was able to see it before he runs off. In the season finale, Nick brings Juliette over to Monroe’s place so that he can change in front of her, to prove his Grimm heritage, but before Monroe could “allow” himself to be seen by her, Juliette collapses from the scratch made by Adalind’s cat. Monroe is now exploring a relationship with Rosalee, although they are taking their time due to their pre-existing friendship. While running the Spice Shop, Monroe comes into contact with Sean Renard who is complaining of obsessive behavior. Monroe says he can make the compulsions go away, but he needs both Sean and the person he is obsessed with together. In (Season 2 Episode 11) he discovers that the obsession Sean has been fighting is for Juliette, which puts him in a very difficult and awkward situation.

Sean Renard

Captain Sean Renard, played by Sasha Roiz, is Nick’s politically adept superior officer and a member of the creature community of unknown origin. Nick is totally unaware of his status and he seems to be a potential threat. In episode 12, he is addressed as Your Highness, further implying that he belongs to royalty in the creature community. He is a prince connected to Royal Blood. He also references my canton, implying a leadership role, which is further shown when he appears to police and protect wesen engaging in illicit acts. He seems to want a return to the old ways. In episode 24 (Season 2, Episode 2), he consumed a potion that would make him pure of heart so that he could wake Juliette, wanting to keep her active so that he could ensure Nick’s continued presence in his city. In episode 30 (Season 2, Episode 8), his brother, Eric, mentioned to Adalind that Sean Renard’s mother was a Hexenbiest and that he is only half of a royal (hence one reason why Catherine Schade referred to him as a bastard). Because his mother is a Hexenbiest but his father isn’t Sean is a half-Hexenbiest. It is implied that Sean would have inherited Eric’s position had he been legitimate. He has begun to develop a complicated attraction to Juliette due to his role in awakening her from the coma, but is attempting to resist it due to his artifical nature and because he is, in his own way, an honorable man.The most likely explanation is that separating Juliette from Nick interferes with his plans for Nick. In fact he stated outright that he wanted to awaken Juliette because it served his purposes.

Wu

Sergeant Wu, played by Reggie Lee, is a policeman who works with Nick and Hank; he tends to do the ‘grunt work’ for them, running down facts and information. In episode 15 (Season 1, Episode 15), when Adalind gave Hank some hexed cookies, Wu ate one. This caused him to ingest things that were inedible, such as paper clips, for several more episodes. Finally in episode 17 (Season 1, Episode 17) Rosalee created a potion to save him.

Rosalee Calvert

Rosalee Calvert, played by Bree Turner, is a Fuchsbau and sister to Freddie, proprietor of the herb shop used as a front for the Geier organ trafficking business seen in “Organ Grinder“. After Freddie’s death in “Island of Dreams“, Rosalee comes to Portland to sort out her brother’s affairs and decides to stick around. Prior to her arrival in Portland she spent her earlier years trying to follow up her parents’ profession as an apothecary, but didn’t like the job, in spite of her aptitude for it. She became hooked on a highly-addictive Wesen-oriented drug street-named ‘Jay’ and left Portland to get clean. After deciding to keep her brother’s shop running, Rosalee assists Nick and Monroe in their efforts by providing additional information and remedies to supernatural problems. Rosalee shares a powerful connection with Monroe. In “Quill“, they go on their first date and share their first kiss, after which Rosalee uncharacteristically attempts to seduce Monroe. This seduction attempt turns out to be the manifestation of a common symptom from the Wesen virus Rosalee had been exposed to during their date. After being cured, Rosalee and Monroe agree that the attraction between them was real, but decide to take it slow before becoming intimate with each other. She was first seen in episode 15 (Season 1, Episode 15).

Adalind Schade

Adalind Schade, played by Claire Coffee, is a Hexenbiest who seemed to be working for Renard, who gave her various tasks involving the supernatural world. In Episode 17 (Season 1, Episode 17), after ingesting Nick’s blood, she becomes a completely normal human. Renard tells her that she is no longer useful to him since she is no longer a wesen. Although not a true Hexenbiest anymore, Adalind retains her knowledge and skill with potions; Nick now describes her as a witch. In Episode 22 (Season 1, Episode 22), she poisons Juliette by having a poisoned (or magicked) cat scratch her. Although Monroe and Rosalee are able to retrieve the cat, Nick finds that Adalind has vanished. Sometime later, Adalind resurfaced in Vienna to rendezvous with Eric Renard. It has been revealed that she will return to Portland. Initially recurring, Coffee was promoted to the main cast, beginning with Episode 34 (Season 2, Episode 12).

Recurring Characters

Catherine Schade

Catherine Schade, played by Jessica Tuck, is a Hexenbiest who is Adalind Schade’s mother. She is first seen in episode 17 (Season 1, Episode 17). She taught everything she knows to Adalind about being a Hexenbiest. The very last time she spoke to her daughter was episode 17 (Season 1, Episode 17) when Adalind ingested Nick’s blood, removing her Hexenbiest abilities. She was accidentally killed in episode 24 (Season 2, Episode 2) by Kelly Burkhardt when trying to figure out how to cure Juliette from her coma.

Eric Renard

Eric Renard, played by James Frain, is the brother of Sean Renard. He is fluent in English, speaking with a neutral English accent. He also knows French and appears to reside in a Norman-style castle. He made his first appearance in episode 23 (Season 2, Episode 1) when he is seen approaching a man as he is being tortured. He asks him the names of people in the Resistance. He later gets a phone call from Marnassier. In episode 24 (Season 2, Episode 2), Eric is in bed when Sean calls from Portland to ask if he was involved with sending Marnassier to the United States, chiding him for not being more discreet. Eric responds that “the family” is not as patient as Sean wants them to be. Sean tells Eric that Marnassier is dead. He is a recurring character in Season 2.

Dr. Harper

Dr. Harper, played by Sharon Sachs, is a medical examiner, who occasionally works on Nick and Hank’s cases. In episode 13, she was beaten by a Schakale who was looking for the Coins of Zakynthos. Throughout “Three Coins in a Fuchsbau“, Harper was referred to as “Parker.”

Bud Wurstner

Bud Wurstner, played by Danny Bruno, is an Eisbiber who first encounters Nick when he is repairing his fridge. He is initially frightened of Nick, believing him to be as violent as the Grimms of myth. Because of this, Bud behaves in a subservient manner towards Nick, offering to fix things and giving Nick gifts. It is only after Nick calls upon Bud for help in a murder case that Bud realizes Nick is a good person and the two become friends, although he is still somewhat jittery when he and Nick meet.

Kelly Burkhardt

Kelly Burkhardt, played by Mary Elizabeth Mastrantonio, is a Grimm, who is also Nick Burkhardt’s mother. Her first appearance was in the last episode of season 1 (episode 22). For 18 years Nick had believed that both of his parents had died in a car crash. Only after learning that he was a Grimm did Nick find out that his parents had actually been murdered. In reality, Kelly has been alive this whole time. When Nick reunites with his mother in episode 23 (Season 2, Episode 1), Kelly tells Nick that his Dad was killed in the car crash, but that the woman who had been in the car with him (and had been identified as Nick’s mother) was actually Kelly’s friend who the killer mistook as the intended Grimm (Kelly). Kelly explains to Nick that she had pretended to be dead for 18 years because it was the best way for her to protect Nick from his father’s murderer. Kelly assists Nick with his investigation on the attacks by the Mauvais Dentes. Nick takes his mother to Marie’s Trailer, which Kelly and Marie had bought together after their father had become ill. Later in episode 24 (Season 2, Episode 2), Kelly tries to find out how to cure Juliette by talking to Catherine Schade. Catherine tells Kelly that a prince is in Portland, but Kelly accidentally kills Catherine before being able to find out the prince’s identity. At the end of the episode Nick, thinking that she was going to Zakynthos to destroy the Coins of Zakynthos, takes Kelly to the train station. After Nick drives away from the station, Kelly is seen stealing a car instead of entering the station.

Marie Kessler

Marie Kessler, played by Kate Burton, was Nick’s aunt and a Grimm; she told Nick that she worked as a librarian, but whether she ever had this job or simply worked as a Grimm full-time is unclear. She was injured by a Reaper when she came to visit him, although she was already dying of cancer. Despite assassination attempts being thwarted by Nick and Monroe, she eventually died of her injuries in Season 1, Episode 2—her last words being to remind Nick to fight “the bad ones”. She left Nick her trailer, containing all of her books and tools about the creatures that he would face as a Grimm, which he keeps in a storage lot and consults when necessary.
