List of Grimm characters

The following is a list of the cast and characters from the NBC television series Grimm.

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. This power 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 some time, but 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 life as a grimm. The two tend to cross when he works cases that involve wesen, which are the creatures of the grimm world. As Nick dives deeper into his grimm heritage, he begins to train with Monroe to learn about the wesen in Portland and to use the weapons that his aunt Marie left behind. As of episode 19, Nick had successfully killed three reapers, creatures that are sent out to kill grimms (hence the grimm reaper title). He kills the first in defense of Marie, and the other two are killed in self-defense after being sent Nick's lead suspect in a case. The latter two have their heads sent back home with a note saying to send the best next time. In the season finale, Nick's worries about a scratch Juliette received from Adalind's cat force him to reveal his grimm heritage to her, which makes Juliette believe he has gone crazy. When bringing her to the trailer is not enough to convince her, they go to Monroe's house so that Nick can show her his blutbad form, though before Monroe can show her, Juliette collapses. Rosalee discovers that Juliette is going through memory loss, but 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 that his mother is alive and well in the first episode of season two. At this time, but he is still does not know her true motives or agenda. At the end of season three, Nick's grimm powers are removed by Adalind as a result of sleeping with her – she had disguised herself as Juliette. He regains his powers in "Highway Of Tears".

Nick later learns that Adalind is pregnant with his child, which is revealed to be a boy when Adalind gives birth. She names the boy "Kelly" after Nick's mother. At the beginning of Season 5, Nick and the group become involved in a secret war between Hadrian's Wall (HW) – a secret government organization that Trubel and Meisner are a part of – and Black Claw, a worldwide wesen revolutionary group. Nick sells his home and buys a secret, fortified loft to better protect Adalind and Kelly. As Nick and Adaind raise Kelly together, they grow closer and Nick shows himself to be a devoted father. At the end of "Wesen Nacht", Nick is shocked to learn that Juliette has survived, as is now working for HW under the new persona of Eve. In "Map of the Seven Knights", Nick comes into contact with Monroe's uncle, who is killed by Black Claw. After avenging his murder, Nick acquires twenty new grimm books, a new cache of weapons and three more map keys. With these, he figures out the location of the Templar's hidden treasure. In "Key Move" and "Into the Schwarzwald", Nick and Monroe travel to Germany to find this treasure. The group discovers that the treasure is a stick of wood with healing properties. Nick learns that Renard is working with Black Claw to become Mayor, and that Renard may use Diana to get to Adalind. By this time, Rosalee reveals that Adalind's hexenbiest powers have returned while he was in Germany, but keeps it a secret until Adalind herself reveals it. Adalind is forced by Renard, Bonaparte and unknowingly Diana, to take Kelly and leave Nick. Nick becomes distraught over losing his son and girlfriend and fights hard to get them back, which culminates to a vicious fight between him and Renard at the police station. Nick is arrested for assault, but is later set free by Eve, Trubel and Wu. Diana warns Nick that Black Claw is coming for them. He subsequently leads the group into an underground tunnel underneath his loft while he stays behind to deal with the attackers. Despite overwhelming numbers and the stick's healing powers, Nick kills all of the assailants before being confronted with Renard and Bonaparte. Before Bonaparte can kill Nick, he is killed by Diana, who learned Bonaparte had tortured Adalind to give up their location.
