- Badass Bookworm: She killed her own assassin, while dying of Cancer and was a librarian after all.
- Bald Woman: Because she's dying of cancer.
- Covered with Scars: Her doctor reports this to Nick.
- Crazy-Prepared: Aunt Marie was prepared with certain rare items and weapons for any supernatural threat.
- Dying Moment of Awesome: Dies, killing an Assassin sent to murder her, with her bare hands.
- Hidden Depths: If Farley Kolt is to be believed, she was willing to buck both their families and quit the Grimm life to marry him. Then she had to give that up to take care of Nick.
- Interspecies Romance: She was once engaged to Farley Kolt, a Steinadler.
- It's Not You, It's My Enemies: Aunt Marie's reason for being an old maid.
- Maiden Aunt: She never married due to the responsibilities of raising Nick and being a Grimm.
- Mentor Occupational Hazard: Teaches Nick what it means to be a Grimm, and is dead within 3 episodes.
- Never Mess with Granny: While dying of cancer, she manages to hold her own against a scythe-wielding monster using a knife and the cane she was using to walk. While bedridden in the hospital, she stares down someone strong enough to later rip someone's arm off by accident. She later fights off her human would-be-assassin and kills him with his own knife before she dies.
- Parental Substitute: To Nick, who lost his parents when he was twelve. In his words, she is his family.
- Secret Keeper: She knew that her sister was still alive, and kept the secret for eighteen years.
- We Hardly Knew Ye: Is truly dead by the third episode.
Marie's sister and the source of Nick's Grimm genes, killed along with his father in a car crash when Nick was twelve. It later turns out that she was murdered by Wesen in an attempt to steal the Artifact of Doom she was entrusted with guarding. Turns out that she hadn't been killed, but she took the opportunity to fake her own death in order to hunt down the critters responsible for her husband's murder, leaving Aunt Marie to take care of Nick. She turns up again in the Season 1 finale tracking down Kimura.
- Action Mom: Kicks just as much ass as Nick, being that she's also a Grimm. Kelly is clearly the most Badass of the main cast, with Nick, Meisner and Renard competing for a distant second place.
- Back for the Dead: In "Headache" she's killed by Kenneth and his goons with Juliette's help.
- Back for the Finale: She appears as a spirit alongside her sister to help Nick defeat the Zerstorer.
- But for Me, It Was Tuesday: She's killed so many Wesen that she can't even remember them all. Best exemplified in Synchronicity when Nick has to remind her that she killed Adalind's mother and she responds with a chipper "Oh yeah, I'd forgotten about that."
- Crusading Widow: She's spent the last couple of decades or so hunting down the Wesen who killed her husband and best friend.
- Death by Irony: Grimms are most notorious among Wesen for beheading their opponents. This is not lost on Kenneth.
- Determined Widow: Shows signs of the advisor kind to Nick.
- Determinator: Willing to go to incredible lengths to achieve her goals, including pretending to be dead for decades to keep her enemies eyes off her son.
- Dramatic Irony: Kelly has a soft spot for Adalind and her baby. However, she unwittingly killed Adalind's mother in an earlier episode.
- Freudian Excuse: Her father impressed on her the brutal and horrifying nature of the Wesen she would face as a Grimm, starting when she came into her heritage at age ten; she was too terrified to sleep properly for months. Small wonder she grew up to hunt them as monsters.
- Heroic Comedic Sociopath: Kelly seems to enjoy what she does, and the show gets a couple of funny moments (as noted above) from her sheer casualness with killing Wisen.
- Hunter of Monsters: Her father took her and her sister on "hunts" starting when she was eighteen. Presumably, she kept it up.
- Improbable Weapon User: Makes good use of a rolled up news paper in "The Kiss".
- Knight Templar: Much more extreme than her son.
- Mama Bear: Her introductory scene in the series involves saving Nick from a bad guy.
- Meaningful Name: Kelly can be translated to mean "Warrior" or "Fighter," and she's the best of both in the entire series.
- Missing Mom: To Nick for complicated reasons.
- Mommy Had A Good Reason For Abandoning You: She realized people were trying to kill her and she wanted to keep Nick safe, since he hadn't developed his powers yet.
- Offscreen Teleportation: Apparently her favorite way to enter a room.
- Quirky Curls: Her standard hair style.
- Spanner in the Works: Her involvement in "Synchronicity" is what sets off the Comedy Of Errors that brings all of the seasons plot threads together without any of the characters involved realizing what's going on:
- Renard arranges for the Resistance to extract Adalind from Switzerland, not knowing that Kelly is the agent or even that she is working for the resistance.
- Kelly rescues Meisner and Adalind from the Verrat, but since Adalind and Kelly have never met face-to-face neither recognizes the other.
- When Kelly realizes that the resistance operation has been compromised, she arranges for the flight to divert to Portland, hoping that Nick will protect Adalind not realizing that Adalind is originally from Portland, that she and Nick have a history, and never having heard the name Sean Renard. For operational security she doesn't tell Adalind that they're going to Portland.
- When they reach Portland, Adalind assumes that Kelly was working for Renard all along, only to be as surprised as anyone when Kelly brings her to Nick's house. Realizing what a colossal mix-up there has been, she goes to Renard for help, where a surprised Renard lets her in.
- Meanwhile in Europe, based on sketchy evidence, Prince Victor correctly guesses for the wrong reason that Adalind and Kelly have flown to Portland, figuring that Adalind wanted to go home, not knowing of her connection to Nick, the involvement of Kelly, and having only a sketchy idea of Adalind's relationship with Renard.
- Stuffed in the Fridge: The Royals leave her decapitated head in a box for Nick to discover.
- Sugar-and-Ice Personality: Is usually very cold and aloof, but she clearly loves her son and later shows a soft spot for Adalind and her newborn daughter.
- Van Helsing Hate Crimes: She doesn't seem to have been nearly as careful as Nick is at making sure the Wesen she kills are completely deserving. She tries to kill Monroe just because she sees he's a Blutbad, and it takes Nick pulling her off and physically blocking her from reaching him to keep her from finishing it.
- Walking Spoiler: Is this for first season, but becomes more a case of It Was His Sled in later seasons.
Theresa "Trubel" Rubel
A young Grimm who drifts into Portland at the end of Season 3. Unaware of her nature as a Grimm, she thinks the monsters she keeps seeing means she's gone crazy. Nick takes her under his wing to help her cope. She's later revealed to be Nick's third cousin from his mother's side of the family.
- Action Girl: When she first arrives in Portland she's already very handy with a machete and an accomplished killer of wesen, even though she doesn't know what they are or why they attack her.
- Adorkable: She's very earnest towards Nick and Juliette
- Anti-Hero: She's brutal in a fight and not opposed to shaking people down for an interrogation.
- Big Eater: Anytime we see her at the dinner table, expect her to have huge portions and then seconds afterwards. Understandable as a street urchin who often didn't have enough to eat.
- Boyish Short Hair: Most likely done to exemplify her status as Tomboy and an Action Girl.
- Broken Bird: She's actually a Grimm, and never knew what those strange creatures were.
- The Bus Came Back: A few times. Trubel makes a habit of returning to the story right when all hell breaks loose, such as in "Headache" after The Royals made a move to capture Diana and killed Nick's mother.
- This happens again in the penultimate episode "Zerstorer Shrugged" after the titular monster escapes from the mirror and wreaks all sorts of havoc on Portland.
- But Now I Must Go: Voluntarily leaves Portland at the end of The Grimm Who Stole Christmas to help keep Joshua Porter safe.
- Leaves again early in season 6 to help Hadrian's Wall eradicate Black Claw entirely.
- Character Development: Goes from a mentally unstable drifter with trust issues to confident and knowledgeable warrior who'd do anything to protect her friends.
- Chess Motifs: Has a black knight piece that she carries with her at all times. She feels a connection to it since it moves in unpredictable ways and is different from the other pieces, just like her.
- Comically Missing the Point: After she, Monroe, and Rosalee go to the latter two's home to give a potioned Juliette looking like Adalind and Nick some privacy in order to complete a ritual to re-power Nick which involves consummation, the following exchange takes place:Monroe: ...Because I gotta stop thinking about Nick and Juliette and Adalind or Adalind with Juliette because the whole thing is like some bizarre, convoluted ménage à trois.
Rosalee: Monroe, we have a guest!
Trubel: Oh, I know what convoluted means.
Rosalee and Monroe gulp beer.
- Cool Bike: Gets one courtesy of Hadrian's Wall. Nick and Hank are impressed by it.
- Covered in Scars: She has claw and slash marks all over her back, probably from all her unexpected Wesen attacks.
- Contralto of Danger: Despite being the youngest major female character, she's got the deepest voice.
- Deadpan Snarker: Makes several sarcastic comments about the weirdness of her life.
- The Drifter: She's drifted across the whole US over the course of her short life.
- Eerie Pale-Skinned Brunette: A lot like Nick and his mother. In fact, it's beginning to look like the go-to physical trait of Grimms at this point.
- Guile Hero: Quite clever and good at thinking on her feet to manipulate people when the situation calls for it.
- Hell-Bent for Leather: The only consistent part of her wardrobe has been a leather jacket.
- Knife Nut: She has a switchblade on hand as backup in case she doesn't have her machete.
- Little Miss Badass: She's effectively viewed as such by Nick, despite her being 21.
- Machete Mayhem: Her Weapon of Choice.
- Mind Rape: Inverted. When the Gedachtnis Esser attacks her to take her memories, it only gets so far into her memories before realizing she was a Grimm. By taking her memories of the horrific wesen suddenly attacking her in her youth, it alleviated her of those troubling memories and made her a bit more mentally stable person while he goes Mad From The Revelation.
- No Social Skills: Years of being on the run and having random people turn into monsters and try to kill her have left her this way.
- Parental Sexuality Squick: Due to Nick and Juliette's growing status her Parental Substitutes she becomes incredibly uncomfortable when they're having sex and leaves the house for an entire day.
- Ping-Pong Naïveté: Goes from pragmatically saying that Nick and Juliette should stop focusing on the awkwardness of the magic ritual to restore Nick's Grimm powers via sex, but becomes incredibly awkward when it actually happens and has no clue what a ménage à trois is. If she was being serious.
- Put on a Bus: Leaves Portland with Joshua Porter to help him get his life back together and protect him from the Verrat at the end of The Grimm Who Stole Christmas.
- Sanity Slippage: Since she never had a Grimm mentor to explain things to her, she's been getting steadily more unhinged since she started seeing "monsters." But it seems to have reversed itself. See Mind Rape.
- She Cleans Up Nicely: She really does look nice when dressed to the nines.
- Statuesque Stunner: Is tallest major female character in the series, being only a few inches shorter than Nick. Likewise see She Cleans Up Nicely.
- Steven Ulysses Perhero: Theresa Rubel, aka TRubel/Trouble.
- Strong Family Resemblance: Jacqueline Toboni could easily be David Giuntoli's little sister. Taken with other similarities in the character's personalities this may be an indication that Nick and Trubel are related a little more closely than "some time in the last six hundred years." David Giuntoli has even acknowledged this in interviews. They're eventually revealed to be third cousins on Nick's mother's side.
- Sherlock Scan: A couple of times in "My Fair Wesen"
- Shower Scene: Two of them in her introductory episode. However, since she spends the majority of them crying and trying to clean off blood, they're a definite case of Fan Disservice.
- Too Spicy for Yog-Sothoth: When a Gedatchnis Esser, a Mind Flayer-like Wesen, attempts to steal her memories, he ends up a screaming wreck on account of absorbing all of her traumatic experiences, and she sleeps well that night for the first time in years.
- Troubled, but Cute: Her name is Trubel. She's also an adorable punk-rocky girl in her late teens/early twenties.
- Unkempt Beauty: But she's also acknowledged as attractive when covered in dirt and posing as a homeless person.
- When She Smiles: Her rare smiles are incredibly adorable.
An elderly Grimm on his deathbed who arrives in Portland not long after Trubel. He seeks Nick to give him his collection of Grimm-related things, as his own son hasn't inherited the family powers.
- Cool Old Guy: He's in his sixties and dying of an unspecified illness, but still manages to kill a Verrat assassin with a sword.
- Heroes Prefer Swords: His weapon of choice, a medieval broadsword.
- I'm Dying, Please Take My MacGuffin: The whole reason he came to Portland in the first place. His son is a Muggle Born of Mages, so Nick's the only other Grimm he knows of who's qualified to protect his family's key to the mysterious treasure the Royals want.
- Incurable Cough of Death: Naturally has one as a symptom.
- Soap Opera Disease: What's killing him is never really specified. He just keeps coughing.
- He appears to be suffering symptoms of angina, which cause pain and shortness of breath, therefore creating an urge to cough.
Not technically a Grimm, but since he's involved the Grim Treasure Key Myth Arc, he best fits here. The son of Rolek Porter. Because he didn't inherit the family's Grimm powers, he thinks his dying father is going crazy when he takes him on a cross country journey to fight monsters. (Nick points out that Josh's Grimm abilities might be latent, as his own didn't manifest until he was an adult.)
- Action Survivor: Despite being a Muggle, when he's attacked, he's able to escape thanks to quick thinking and some carefully thrown objects.
- The Dutiful Son: Despite not believing his father's stories about monsters and a treasure map, he helps his father across country to fulfill his dying wish. He is later seen returning his father's ashes home.
- I Just Want to Be Normal: Once he discovers that his father's stories are real, he's glad he can't see Wessen, as he enjoys his mundane life. This comes back to bite him in the 4th season when the Verrat chase him out of his house and force him into hiding in an attempt to steal a key he no longer has.
- Muggle Born of Mages: His dad's a badass Grimm and comes from a long line of Grimms stretching back to the Middle Ages. Josh is completely normal.
- Non-Action Guy: He's completely unsuited for action.
- Puppy-Dog Eyes: He seems to constantly look sad or scared by the news he receives. It adds to his Woobie status.
- Resigned to the Call: Seems to develop the attitude, knowing he's going to get attacked by Wessen, even if he can't see them, so he might as well learn about them.
A hapless Eisbiber who was fixing Nick's fridge when he found out that Nick was a Grimm. Subsequently, he's been a source of comic relief (for us, the viewers) and frustration in Nick's life. The latter because he's hilariously misinterpreting the situation and the former because he shows up at very awkward times trying to be very, very nice so that Nick doesn't kill him (or so he thinks). After several comic appearances, he has an episode proper that establishes more about both Bud and Eisbiber. Subsequently, he shows up again in Season 2 multiple times with far bigger appearances than before almost getting killed in one of them.
- Adorkable: Easily flustered and having a tendency to put his foot in his mouth when he inadvertently blurts out whatever he's thinking at the moment.
- Call-Back: When he shows up in season two, he asks about the blanket and pies that his wife made for Nick and Juliette in season one. The blanket itself shows up as the blanket Nick is using.
- Distressed Dude: He and Monroe are kidnapped by the Wesenrein in Season 4.
- The Ghost: Bud's wife. He frequently refers to her but we've never seen her on-screen, even when her presence would be fully expected. Bud often describes her as The Dreaded.
- Grew a Spine: Throughout the series, Bud is building one, iota by iota. It appears full force in "The Tribunal," when he calls the Wesenrein the sick fanatics he knows they are.
- Incredibly Lame Visual Pun: he and his family are all big fans of Oregon State University's football team.
- Lovable Coward/The So-Called Coward: Ironically he's one on the braver members of his species.
- Meaningful Name: A friendly and humble family man named "Bud."
- Motor Mouth: Has a habit of speaking incredibly fast, normally show to show how nervous he is to the present situation. Which considering company he keeps, comes up a lot. He often ends up with his foot in his mouth.
- My Species Doth Protest Too Much: When his fellow eisbibers choose to not have one of their own testify against a man who's not only murdered another eisbiber but has been extorting the entire community for years, he admits that for the first time he was ashamed to be part of a race that is so cowardly in nature. Nick admits that Bud himself was very brave to continuously help Nick out with small favours even though for all he knew Nick planned on killing him.
- Open Mouth, Insert Foot: It's practically his mother tongue.
- Plucky Comic Relief: How plucky he is can be up for debate, but so far his only major impact on the show has been comic relief, and he is rather persistent in his bugging Nick.
- Recurring Extra: Has something of a Sixth Ranger vibe to him as well as he starts to get more involved in the gang's antics.
- Starred in a web series, "Meltdown," which involved Bud having to fend off a cracher-mortel zombie.
A fuschbau that first appears in "Organ Grinder". He runs an apothecary. Unlike many, there's the stuff up front for the humans and then there's the stuff in the back for the Wesen. He reappears in "Island of Dreams" only to get killed by two drug-addicted Skalengecks.
- Back for the Dead: Was first introduced in "Organ Grinder". When we see him again in "Island of Dreams", his first and only scene (not counting flashbacks) is the one where he's killed.
- Big Brother Mentor: Freddy was the only member of Rosalee's family to maintain ties with her while she was on the streets and was the one to help her recover from her addiction to J.
- Dark and Troubled Past: After his death, Rosalee and Munroe find an envelope of fake passports with his face on them.
- And was apparently part of the resistance.
- Wasn't just his past; he was also a well-known vendor of Wesen drugs and human organs up until he died.
- He was also the liaison to the Wesen Council (sort of like the Reapers, only they put down any "unruly" Wesen who run the risk of exposing the others to the world).
- Not to mention his shady business dealings with Geiers; he sells their product... human organs from teens.
- La Résistance: He helps those Wesen trying to escape the Old World by providing means to fake documents.
- Underground Railroad: He is the last stop for runaway Wesen.
Monroe's ex-girlfriend from his pre-Wieder days. She sees him again for the first time in years after her brother, Monroe's friend Hap, is almost killed when his house is blown up. Unlike Monroe, she makes no attempts to deny her more violent urges or to fit into human society.
She died in "Over My Dead Body", when she sacrifices herself to save Monroe - and by extension Nick, and is shot by a Skalengeck, bleeding out in Monroe's arms.
- Back for the Dead: Came back in "Over My Dead Body" only to die protecting Monroe.
- The Big Bad Wolf: Played out this scenario with three Bauerschwein brothers, only for the surviving brother to do it to her brothers.
- Biker Babe: First introduced riding on her bike, and normally dresses the part.
- Cute Monster Girl: Angelina fits the bill, being very tough, but very cute, and very easy to underestimate.
- Dark Action Girl: Angelina is a dangerous fighter, and incredibly strong. So much so she believed she could handle Nick (who was new and inexperienced at the time, by the time a rematch becomes possible its clear that ship has long sailed), she's likewise very morally shady
- Destructive Romance: Her relationship with Monroe is treated this way. She makes him slip towards old habits, and his new lifestyle of self-control pisses her off as much as his influence tempers her.
- Died in Your Arms Tonight: In Monroe's in her final episode.
- Evil Counterpart: To Juliette, though she's not really "evil", per se, but more prone to fits of anger and certainly more abrasive and agressive.
- Fiery Redhead: Again, not exactly evil, but she's definitely not an angel.
- Heroic Sacrifice: Dies saving Monroe, by taking the bullet for him.
- The Lad-ette: Drinks? Check. Has casual sex? Check. Aggressive personality? Picks fights? Check and check.
- New Old Flame: She and Monroe still have feelings for each other, despite the many issues that make it clear they're wrong for each other.
- Sherlock Scan: She performs one when she pretends to be Nick's partner. The other cop present is greatly impressed by her ability to deduct exactly how a man was killed and she even finds evidence the other cops missed. She is cheating because she is the one who killed the man.
- Teeth-Clenched Teamwork: With Nick in "Over My Dead Body".
A daemonfeuer who appears in "Plumed Serpent". She loves her father such that she would rather have him die in combat versus homeless and in bed. To this end, she lures Nick into a fight with him before faking her own death. Though she has yet to show up again, the episode strongly suggests she will.
- Beauty Is Bad: "Hot" puns aside, she's a very enthusiastic femme fatale and a spectacular bitch.
- Evil Redhead: She kidnaps Juliette so Nick will have to fight her father.
- Manipulative Bitch: Plays Nick in order to rope him into a battle to the death with her father; she also takes advantage of her father's confusion to motivate him into playing the dragon to Juliette's damsel in distress.
- Our Dragons Are Different: A daemonfeuer, a dragon-like Wesen.
- Proud Warrior Race Girl: A firm believer in Daemonfeuer warrior traditions, she sincerely wants her father to die according to them rather than living on in misery.
- Stalker with a Crush: She follows Nick home and answers his phone when Juliette calls.
- Yandere: Shows signs of this towards Nick, partially down to her kinds near admiration and respect for Grimms.
- Bitch in Sheep's Clothing: Initially appearing bubbly and cheerful in her initial meeting with Adalind, Catherine quickly begins showing her inner bitchiness; on top of following suit in kicking her depowered daughter aside, she also has no problem using her Game Face to frighten Rosalee into cooperating with relatively minor requests.
- The Dragon: To Renard during Season 1.
- Evil Matriarch: To Adalind.
- Evil Is Petty: Willing to woge out and threaten death if it means getting a discount of fifty dollrs.
- Eyeless Face: When Woged.
- Femme Fatale: Even gives her daughter tips on living up to the role.
- Hot Witch: Like mother like daughter - Catherine has no problem in keeping herself looking pretty and fashionable.
- Stage Mom: Her affections toward her daughter seem very dependent on Adalind's success; true to form, once Adalind is depowered, she's cast aside as a failure.
- Witch Species: She's a Hexenbiest.
Juliette's college roommate, she temporarily shelters with Nick and Juliette while fleeing her abusive husband, Joe. Once she arrives Nick realizes she's a fuchsbau, though she doesn't notice that he's a Grimm. Juliette tries to get her to open up about her wesen nature but Alicia is reluctant. She's frightened when she learns about Nick's Grimm status but makes peace with Juliette and herself when Nick and Juliette help get Joe out of her life for good. She moves into an apartment in Portland but we haven't seen or heard about her since.
- Adult Fear: She runs away from an abusive husband only to have him pursue her and she doesn't know that she can trust her friends with the truth about who she or her husband are.
- Curb-Stomp Battle: Juliette and Alicia beat the tar out of Joe when he pushes his way into the house, without assistance from Nick.
- Domestic Abuse: Alicia's husband Joe is a klaustreich, a serial abuser and he stalks her from their home in Washington to Portland.
- Oh, Crap!: When Juliette tosses out that Nick is a Grimm, Alicia panics and makes a run for it. Nick is only just managing to talk her down when her abusive husband sucker punches him and crashes into the house.
- You Are What You Hate: The secretive kind. Alicia has a serious hang-up about being wesen and refuses to even acknowledge it to Juliette. It probably doesn't help that Juliette starts stammering and crying when trying to bring it up. She finally seems okay once Juliette and Nick help her get rid of Joe.
An old friend of Renard's Mother and wise and powerful Hexenbiest. Other Wessen go to her for magical advice.
- Back for the Dead: She returns in "You Don't Know Jack" to help with Renard's phantom bleeding, only to have her throat slit by Jack the Ripper (who ironically turns out to be a possessed Sean) before she can find a solution.
- The Last of These Is Not Like the Others: Is the latest Hexenbiest introduced on the show and the first non-white one.
- The Vamp: She shows the ability to take a confrontational and enraged Nick and get him about two seconds from making out. She then says Juliette will be able to a lot more than just that when her powers become fully developed.
- Witch Species: Is a Hexenbiest.
A Resistance Movement opposed to the Royal Families and the Verrat.
Renard's friend and a mole within the Royal Family. Currently tracking down Adalind and heavily implied to be the one who killed Prince Eric Renard. He didn't actually do it - that was Meisner - but he facilitated it.
- Badass Long Coat: Almost always seen wearing a cool trench coat.
- First-Name Basis: For the longest time, he was known as "Renard's Confidant" or "Castle Spy". He only gained a first name after several appearances.
- Forgotten Fallen Friend: Although he gave his life to ensure Adalind and Diana made it to safety, not one word is spoken of his heroic sacrifice after the fact by Renard, Meisner, or Adalind.
- Heroic Sacrifice: In "The Show Must Go On" still suffering from his beating, he takes a gun and waits to ambush Viktor and his men. He takes out all but Viktor, and would have killed him too, if he didn't run out of bullets.
- The Mole: For Renard in Europe.
- Omniglot: Seems to speak almost as many languages as Renard as it has shown he can speak English, French and German so far.
- Sensitive Guy and Manly Man: Is this with Captain Renard. No points for guessing which one's which.
- Spell My Name with an "S": Is it Sebastian or Sebastien?
An acquaintance of Renard who murdered Prince Eric Renard by planting a bomb in his car and later murdering Eric's father, King Frederick, by pushing him out of a helicopter.

He also has a shadowy role regarding the events of Season 5.
- Delivery Guy: For Adalind.
- Icy Blue Eyes: As befitting his role as the "tough guy".
- It's Personal: Personally executed Konstantin Breslau after he found out he betrayed him.
- Last Stand: Mounts one when Black Claw attacks Hadrian's Wall headquarters, killing any Black Claw member he comes across until Bonaparte and Renard show up.
- Meaningful Name: Martin, comes from the Latin root for Mars, god of war. Quite fitting for such a mighty warrior.
- Mercy Kill: Renard eventually shoots Meisner after Bonaparte, the leader of the local Black Claw chapter and a Zauberbiest, begins torturing Meisner to death.
- Mr. Fanservice: Nicely sculpted chest complete with tattoos.
- Unfinished Business: After his death, he haunts Renard to make him atone for his betrayal.
- Wild Card: Other characters have repeatedly spoken about how he's only interested in solidifying his own power base, and that he's a Loose Cannon.
The Wesen Council
A Wesen organization separate from the Seven Houses and Grimms that govern and enforce Wesen law.
- Enemy Mine: Despite not working with or even seeming to like Grimms and the Royals, the council worked with them to write a law dealing with Grausens, a type of dangerous human with Wesen-like traits, despite not being a Wesen.
- Kill 'Em All: All of them (except for Alexander) are gunned down by a single Black Claw associate.
- Knight Templar: Their focus on maintaining secrecy has caused them to try and carry out murder on a number of occasions. Monroe especially seems to view them this way.
- The Masquerade: They're the ones most focused on maintaining it.
- Reasonable Authority Figure: Despite everything, they can be reasoned with, especially once it turns out the threat isn't what it appears to be.
- Well-Intentioned Extremist: Theyll uphold The Masquerade at any cost, and not without reason; whenever the masquerade is broken, bad things happen (Monroe states that some Witch Hunts were because someone woged on purpose.
A member of the Wesen Council, who ordinarily gives Alexander his assignments.
- Back for the Dead: He's killed by Black Claw along with the rest of the Wesen Council representatives.
- Beleaguered Bureaucrat: Some of the Councils decisions are really boneheaded, but he has to implement them anyway. He even brings up that they don't actually care about his opinion.
- Deadpan Snarker: In Maréchaussée he cuts loose with the snark about the Portland situation, not to mention his own lack of importance to the Wesen Council as anything other than being the one to implement their plans.
- Dirty Business: Whenever the Council decides to do something illegal, he's the one to make the arrangements.
- Only Sane Man: He is smart enough to know that going after Nick is a very bad idea, but the Council wont listen to him.
- Punch-Clock Villain: Hes responsible of enforcing the Councils law, but takes no pleasure in ordering regrettably necessary things to be done.
- Reasonable Authority Figure: When presented with a good alternative that avoids bloodshed he will take it.
- Those Two Guys: With Alexander.
An employee of the Wesen Council, performing assassinations, enforcement, theft, and all sorts of other Dirty Business.

- Dirty Business: Whenever the Council needs something illegal done, he's their man.
- The Dragon: A non-evil version to the Council. He is responsible for dealing with their work outside of headquarters, such as handing out jobs (in "Natural Born Wesen") and occasionally taking care of said jobs himself, like the Graussen incident (in "Stories We Tell Our Young").
- Evil Brit: Although he's not strictly evil.
- Glowing Eyes of Doom: When woged, he gains glowing yellow-green eyes.
- O.O.C. Is Serious Business: When he arrived and asked Nick for help dealing with a murderous wesen, the team felt something was off. They were right.
- Panthera Awesome: He's a Pflichttreue, a wesen that turns into a kind of snow leopard when woged.
- Punch-Clock Villain: While a career criminal, he works in the service of a quasi-governmental body and usually only fulfills actions he deems regrettably necessary.
- Reasonable Authority Figure: He has a job to do but is not without a free thinking mind. When Nick showed him evidence that the target for assassination was not as he thought and didn't need to be killed, he followed the old treaties and left.
- Sole Survivor: He manages to escape as the rest of the Wesen Council is gunned down by a member of Black Claw.
- Those Two Guys: With De Groot.
- Wild Card: He has very different goals from Nick and friends but cooperates with Nick when it suits him.
The Seven Royal Families
The Seven Royal Families
A group of seven powerful families who control the Wesen world from the shadows. For centuries, they've been competing to find the pieces of a map that leads to a powerful and mysterious treasure their former servants, the Grimms, hid away from them after discovering it during the Fourth Crusade.
- Badass Normal: Despite being the apparent de-facto rulers of the Wesen world, they appear to be mere humans, as none of the Royals have been seen to woge like normal Wesen species, aside from Renard, who is of Mixed Ancestry. May be a subversion as comments early on in the show's run from various actors and writers implied that they are actually "Royal Grimms," which may explain this. Prince Kenneth's ability to fight Sean Renard to a standstill was very reminiscent of a Grimm's ability to fight Wesen hand-to-hand, lending credence to this theory.
- The Chessmaster: What many of them seem to be by default.
- Dysfunctional Family: Just ask Sean.
- Hufflepuff House: While there are technically seven royal families, we've so far only met the House of Kronenberg, Renard's family, leaving the other six a case of Take Our Word for It.
- Kill 'Em All: All of the major Royals seen so far (with the exception of Sean and Viktor) are dead by the end of Season 4:
- Eric is killed with a car bomb by Meisner.
- Kenneth is stabbed in the throat by Nick.
- King Frederick is thrown out of a plane by Meisner.
- Meaningful Name: Subverted. Once expects that that "Renards" will turn out to be Fuchsbau, in keeping with the old folklore figure of Reynard, an anthropomorphic fox. At least so far, this appears not to be the case.
- Non-Action Big Bad: Aside from Renard, none of the Royals we've seen have been in a fight.
- Averted with Viktor, who is quite willing to get out there and kill good guys himself.
- Further averted with Prince Kenneth who curbstomps Sean Renard.
- Shadow Archetype: If they are in fact Royal Grimms, they'd be this by default to the more active and nominally heroic Grimms.
- Succession Crisis: Bound to have one. King Frederick is dead and was predeceased by his only son Eric, Fredericks other son Sean is a bastard, their cousin Kenneth is also dead, and while Viktor is still alive and in command of the family, its mentioned that hes sterile, which could set them up for crisis.
- Super Powerful Genetics: Throughout the show's run, there have been hints that there's some special about being a Royal, just like there is for being a Grimm or a Wesen, but it is mostly a Downplayed Trope.
- What Happened to the Mouse?: Despite the Royal Families being the overall Big Bads of the first four seasons they completely disappear in Season 5 in favour of Black Claw. Presumably they are recovering from King Frederick's death and Viktor's usurpation of the throne however considering that their keys were stolen and Diana was found in Season 5 it's odd that there isn't even a representative of the Royals present to resolve these matters. Especially since their are six other Royal Families besides the House of Kronenberg and you would think the loss of three of their keys would be an important matter they'd want resolved.
A Wesen organization that serve the Seven Royal Families as enforcers to maintain order in the Wesen world.
- Ancient Conspiracy: Has been secretly serving the bad guys for at least 100 years.
- Conservation of Ninjutsu: The first Verrat we meet is a solo agent and a legitimately badass Sociopath. Since then we've never seen them except as groups of half a dozen or more who get easily slaughtered by Nick, Renard, or Meisner.
- The Dragon: The leader of the Verrat seems to be the defacto Dragon to the royal family, but they've been so minor so far that they're more like a Mook Lieutenant.
- Secret Police: Seem to serve as this to the Royal Families.
Eric Renard, Crown Prince of House Kronenberg
Captain Renard's older half-brother, who is the heir to their Royal House.
- Ambition Is Evil: His plans are to restore his family to there former position as rulers of Europe.
- Bad Boss: In the finale for season 2, he offers up a man who has worked with him for seven years to a Cracher-Mortal, just to see what the process of the Lazarus Syndrome production looks like. He cheerfully asks if it is painful, and upon being told it is excruciating, he just shows his enthusiasm to start in earnest.
- Big Bad: Of Season 2 as a whole.
- Deadpan Snarker: By way of Gentleman Snarker and expressing mild disdain over just about everything he encounters.
- Disc-One Final Boss: He isn't seen after Season Two when he gets blown up.
- Does This Remind You of Anything?: The Heir to an Austrian royal family is assassinated in his car, sparking off a war.
- Dropped a Bridge on Him: Few people were expecting that the apparent Big Bad would be Killed Offscreen due to Sean making a phone call.
- Establishing Character Moment: The first time we see him, he is in a dungeon very politely interrogating a man who is being so horribly beaten his skin is hanging in ribbons. Eric then answers a phone call and when the tortured man cries out in pain in the background, Eric's response is exasperated at best, "I'm on the phone!"
- Faux Affably Evil: Always polite, never raises his voice (unless he's on the phone) and will watch you writhe in agony with glee.
- Hoist by His Own Petard: It's not clear how much of a role he had in the various assassination attempts against Nick and Renard, but Renard is happy to show him how to do an intercontinental assassination right.
- Out-Gambitted: He underestimated his half-brother's influence, and therefore died in a car bombing in his city of Vienna.
- Really Gets Around: Apparently sleeps around with a lot of women, and never got married.
- Royal Blood: He's a prince, the heir apparent until his untimely demise.
- Royals Who Actually Do Something: An evil version. Although he occasionally visits the opera, he seems to spend most of his time quelling the Resistance and visiting other locations to consolidate his power. When he finally gets his hands dirty with a "zombie apocalypse" as a cover to capture Nick, he fails despite his plan being well-thought out, and loses his life for it.
- Wicked Cultured: Just like his brother, Eric has a taste for the finer things in life. He enjoys classical music (especially from his native Austria), Opera, fine dining and even paraphrases Shakespeare while putting the finishing touches on his plan to kidnap Nick.
- Villainous Friendship: Seemingly with Baron Samedi. Ironically, they both die as a result of the "Zombie Nick" plot crashing.
A Cracher-Mortel that first appeared in "The Waking Dead".
- Badass Baritone: A very deep voice that only deepens when woged.
- Bald of Evil: Often concealed by his hat.
- Beard of Evil: Specifically, a black goatee.
- Character Tics: Samedi has a habit of quietly singing to himself in French when bored.
- The Dragon: For Eric Renard.
- Evil Laugh: Quite a good one, probably best shown in the season 2 finale.
- Lack of Empathy: Really cares nothing for the people he infects and imprisons, content to cause countless deaths to achieve his goals.
- Large Ham: Especially when rousing his zombie minions to battle.
- Meaningful Name: Also the name of a Loa of Haitian Voodoo.
- Nice Hat: A brown top hat worn at a jaunty angle.
- Pre-Mortem One-Liner: "Bonsoir, Mon Ami." (SPIT!)
- Scary Black Man: Certainly dangerous enough to be scary, and boy does he play the part.
- Sword Cane: His distinctive skull-tipped cane turns out to conceal a blade, as revealed in the second-season finale.
- Underestimating Badassery: The Baron thought his mind-control saliva and a locked steel coffin would keep Nick from escaping before he reached Europe. He was wrong.
- Villainous Friendship: Seemingly with Eric Renard. Ironically, they both die as a result of the "Zombie Nick" plan crashing.
- Wicked Cultured: Appears to be a species trait, he has a thing for smart suits, top hats and cigars. He's bilingual and enjoys singing in French.
Stefania Vaduva Popescu
Queen of the Schwarzwald Roma, who are aware of the existence of Wesen and the Royals. It is she who Adalind comes to in order to sell her unborn child. Her true intentions remain unclear.
- The Chessmaster: Particularly in arranging Frau Pech's demise.
- Evil Sounds Deep: Probably the lowest, raspiest voice possible from a non-Wesen female.
- Faux Affably Evil: Despite being devious, manipulative and thoroughly vicious, Stefania manages to make it all the more unsettling by being unfailingly polite and almost genial throughout the worst of her activities.
- God Save Us from the Queen!: She doesn't seem especially tyrannical towards her fellow Roma, but she's undoubtedly more than prepared to kill if it means getting her way.
- Hypocrite: For someone who openly remarks about how untrustworthy and unpredictable Hexenbiests are, Stefania takes great delight in being deliberately obscure about her motives and plans even to her apparent allies.
- Karma Houdini: Has completely gotten away with her cruel actions since she hasn't appeared since halfway through Season 3.
- Manipulative Bitch: Very much a schemer at heart, especially when it comes to getting Adalind and Frau Pech to dance to her tune.
- Psychotic Smirk: Especially noticeable when she forces Adalind to sign her contract.
Viktor Albert Wilheim George Beckendorf
A second cousin to Eric and Sean Renard who comes to take over the family after Eric's death. He is much more proactive and direct in his actions against Sean than Eric was, and takes a particular interest in Adalind's baby.
- Aristocrats Are Evil: On the side of the Royals, and not a nice person.
- Beard of Evil: As his actions get worse and worse, (torturing people, hunting down babies) he now sports a goatee.
- Big Bad: Replaced Eric Renard in this role, and is proving to be much more competent as the prince. Although he hasn't moved fast enough for King Frederick's taste. In the middle of Season Four he was sent back to Vienna and his cousin Prince Kenneth has taken his place. While both Frederick and Kenneth were killed in the Season Four finale (with the former partially by Viktor's hand), Viktor never returned to the Big Bad role.
- Faux Affably Evil: Is nowhere near as good at is as his Cousin was, and certainly doesn't try as hard. However he never the less is not above charm to get what he wants, and to lure others in to a false sense of security.
- I Have You Now, My Pretty: Downplayed. He mentions how pretty Adalind is when he has her captive, and flirts with her rather shamelessly, but has yet to act on it.
- Karma Houdini: Viktor gets away with being responsible for Nick's de-powering in the Season 3 finale, being behind Kelly's death, and killing the King and becoming the King, as neither he nor the major members of the royal families appear after Season 4 and the Big Bad role shifts to first Black Claw in Season 5, then Captain Renard in the first episodes of Season 6, and finally the Zerstorer in the last episodes of the series.
- Kick the Bitch: Tricks Adalind into de-powering Nick by letting her think he has her child (he doesn't) and when she comes to get her child, he throws her in the dungeon and cruelly rubs his deception in her face. That being said, no one could argue that Adalind didn't bring it on herself.
- Manipulative Bastard: Has absolutely no trouble tricking Adalind into thinking he has her baby and doing his bidding.
- Mistreatment-Induced Betrayal: King Frederick, removing him from the operations and replacing him as Crown prince, with Kenneth. Led to him conspiring to have the king killed.
- No-Nonsense Nemesis: Viktor doesn't share Eric's foppish persona or taste for the dramatic. He also has no patience for Renard's bullshit.
- Overly Long Name: Wu seems to think so.Renard: Does the visitor have a name?
Wu: Uh... Quite a name. [takes out a piece of paper with the name on it] His Royal Crown Prince Viktor Chlodwig Zu Schellendorf Von Konigsburg. I may have inadvertently dropped a "von" or a "dorf" or two.
- Put on a Bus: Was shuffled back to Vienna by the King's men at the end of the Season Four episode "Double Date".
- Royals Who Actually Do Something: Is very focused on hunting down Adalind's baby and even joins the chase in the wilderness himself. And unlike Eric, he is willing to get his own hands dirty, like shooting Sebastien and threatening Sean, Sean's mother and Adalind with death if the baby is not returned to him. Then he manipulates Adalind into depowering Nick, and then makes a deal with Meisner to have his uncle killed so he can take over the family.
- The Starscream: It was him who planned his uncle, King Frederick's death, by cutting a deal with the Resistance. Thus he's now taken the throne.
- Took a Level in Badass: Was dangerous before but come Season Five he's taken over as the new King of the house of Kronenberg, making him more dangerous than ever.
- Unreliable Narrator: He tells Adalind that he and Eric were quite close, and then in another scene Sean Renard says that Eric never trusted Viktor.
- Weapon of Choice: A Heckler & Koch P7M13, which he uses to execute Sebastien.
- Wicked Cultured: Less so than Eric, however he still clearly enjoys the finer things in life, he even smokes a Distinguished Gentleman's Pipe while watching Meinser be tortured.
- You Have Failed Me: Has the incumbent head of the Verrat eaten alive by his own minions after he screws up one too many times.
Kenneth Alun Goderich Bowes-Lyon
Another member of the Kronenberg Royal Family, sent to continue Viktor's work in retrieving Diana. He made his first appearance in the Season Four episode, "Heartbreaker." As Viktor was a step up from Eric in his actions, Kenneth is very much a step up from Viktor, in all the most unfortunate ways for the good guys.
- Authority Equals Asskicking: Seems to be the King's new golden boy and spends his entire introductory episode beating the crap out of people.
- Badass Normal: Unlike Sean Renard, who's part Wesen, and Nick, who's a Grimm, Kenneth is merely a normal man who's really good at kung fu.
- Evil Is Bigger: Kenneth is a tall man (his actor is 6ft 5), he literally towers over all others except for Sean (whose actor is 6ft 4).
- Faux Affably Evil: Carrying on the trend, Kenneth is charismatic, and often soft spoken. But he's even more ruthless than Eric or Victor.
- Foil: Kenneth is this to Nick, being a pretty brutal fighter who gets Juliette on his side and has a relationship with her.
- Genius Bruiser: It takes him about two seconds to know that Renard's double agent is loyal to Renard and not the family and he...acts accordingly. He tricks Renard into coming along to a warehouse by using Renard's own spy against him and then killing said spy and then proceeds to hold his own against Renard in a fistfight, including getting back up from a mighty blow without flinching.
- He also sees through Adalind's lie about her second baby being from Viktor, due to knowing he is sterile, and figures out it's actually Nick's, information he uses to turn Juliette against him.
- Hero Killer: Arranged a trap to have Kelly Burkhardt killed in order to retrieve Diana. It worked.
- Kick the Dog: Not only does he kill Nick's mother, but he puts her head in a box and leaves it in the house for him to discover. And then he continues to brag about it in their final confrontation.
- The Last of These Is Not Like the Others: All of the men of the Kronenberg family we've seen so far have been dark-haired middle-aged men with a love for the finer things. Kenneth is fair-haired, young, and seems much more interested in fighting than the arts.
- Made of Iron: He is able to rouse himself from receiving even Renard's worst blows (including ones that actually knock him across the room) without much damage.
- No-Nonsense Nemesis: He doesn't even try to negotiate with Renard. After beating Renard into submission he pretty much lets him know it's his way or the highway.
- Royals Who Actually Do Something: Is just as dedicated as Viktor, in there assigned task, but is even more competent. He also happily does his own fighting and killing.
- The Scapegoat: When a survivor of an attack by Jack the Ripper reports the killer's (Renard's) description to the police, Kenneth (recently killed by Nick) just so happens to fit the description given.
- Too Dumb to Live: Bragged about killing Nick's mother to his face. Three guesses how that turns out for Kenneth.
- Warrior Prince: An evil version, Kenneth is a brilliant and brutal fighter, and happily does his own killing.
King Frederick Renard
The King of the Kronenberg royal family, father of Sean and Eric, and uncle of Viktor.
- Beard of Evil: Has a short grey beard.
- Disney Villain Death: Meisner snuck aboard his escape chopper when he leaves with Diana, and pushes him out of the helicopter and into a freefall.
- Even Evil Has Loved Ones: King Renard is still clearly saddened by the death of his son Eric. Its also implied he still cares about Sean as well.
- Faux Affably Evil: Originally comes across a cheerful, friendly old guy, who is just inquiring about Viktor's progress in finding his granddaughter and the killer of his son. And then he resorts to outright threating to brutally execute his own nephew if he fails him all without changing the tone of his voice. Its says something in the fact that Viktor is clearly terrified of him.
- The Ghost: Is often mentioned, but does actually appear until "Nobody Knows The Trubel I've Known."
- Greater-Scope Villain: As king of one of the Royal families (specifically the one who gives the heroes the most problems) he is top of the villains hierarchy and the most powerful opponent. However he doesn't often get involved in the events himself, instead leaving the planning and plotting to other members, normally the princes.
- Pet the Dog: Its implied, he still holds a level of fondness towards his illegitimate son Sean.
- He also spends most of his appearance in "Cry Havoc" simply playing/being with his granddaughter.
- Out-Gambitted: King Frederick really underestimated Viktor, him stripping him of his title led to Viktor betraying him and organizing his death.
- Really Gets Around: Apparently had several lovers in his younger days, though Sean Renard is his only known bastard.
- You Have Failed Me: All but states this will happen to Viktor is he fails to find baby Diana. Frederick ultimately doesn't kill Viktor when he comes to Portland and pulls him out, replacing him with Kenneth. This turns out to be a mistake when Viktor does an Enemy Mine with Meisner and has him killed.
- And later, after Kenneth is arrested after he was connected to Sam Damerov's death, he leaves the prince to be killed by Nick.
- Your Cheating Heart: How Sean was born, he had an affair with an Hexenbiest and she fell pregnant. Apparently he did this several times (although Sean was the only child born).
The Head of the Verrat whom Prince Viktor installs after the, erm, demise of his predecessor Danilov. He is Prince Viktor's constant companion in the search for Diana until Viktor was sent back to Vienna, after which he serves Kenneth and eventually the King.
- Bald of Evil: In his human form.
- Bald, Black Leader Guy: Fits all the first two and is the leader of the Verrat, although this only makes him Mook Lieutenant to the royals.
- The Dragon: To Viktor and Kenneth.
- Mook Lieutenant: For whoever is in charge of the royal operations.
- Even Evil Has Standards: He is less than pleased to find the more reasonable Viktor replaced by Kenneth, who has a vicious reputation. He is also horrified to witness the fight between Kenneth and Sean Renard.
- Killed Off for Real: Killed in the skirmish by Hank throwing him over the side of staircase.
- Undying Loyalty: To the House of Kronenberg, although he seems to favor Viktor and is not thrilled when Viktor's place in the operation is taken by Kenneth.
- The Spymaster: As head of the Verrat, this is one of the positions he holds for the Royal families.
An organization devoted to hunting down Grimms due to the actions of less discerning ones against peaceful Wesen.
- Demoted to Extra: The Reapers play an important role in the first season, but are only mentioned a couple of times in the second, as the Royals and the Council take center stage as antagonists. They disappear completely after that.
- The Grim Reaper: Turned in a weird way to "the Reapers of the Grimms".
- Off with His Head!: How they typically kill Grimms.
- Sinister Scythe: Their Weapon of Choice, a foldable version.
A ruthless Zauberbiest and one of the major bosses of Black Claw, the Wesen Uprising.
- Bad Boss: Bonaparte casually sacrifices his loyal followers to further his plan, including purposely setting up several agents to die just to provide a distraction for his real plan. Truthfully he doesnt care how many die, as long as their deaths serve his agenda.
- Big Bad: Of Season 5; he and his Black Claw operations drive all the non-one shot cases, and eventually, Black Claw becomes top priority.
- Character Death: Renard is forced by Diana telepathically to stab him after he choked her mother to find Nick.
- The Chessmaster: All of the leaving behind and subsequent deaths of three of his operatives at the safe house Diana was kept at, Zuris capture and breaking for information and Hanks kidnapping, were all part of his plan to lure the three greatest threats (Nick, Trubel and Eve respectively) away from Hadrians Walls base so it would be vulnerable to an attack by his soldiers.
- Diabolical Mastermind: Being one of the leaders of Black Claw, Bonaparte has incredible resources under his control, including an army of Wesen fanatics, several assassins and multiple agents who have infiltrated virtually every major government and civil organization.
- Evil Orphan: Mentions that he grew up without a mother or father, and is the Big Bad of Season 5.
- Evil Sorcerer: Bonaparte is a pureblood Zauberbiest and one of the most powerful magic users to appear, possessing powers that go beyond what most Hexenbiests and Zauberbiests are capable of. He was even able to beat Eve in a magical duel. Bonaparte uses his vast powers solely to further Black Claws, and thus his own, agenda.
- Fantastic Racism: Being a Wesen supremacist, Bonaparte holds a dislike for humans; when Renard offers Meisner a place in Black Claw, Bonaparte declares "There are no exceptions" and starts choking Meisner.
- Faux Affably Evil: Always suave and soft-spoken, conversations with Bonaparte normally start off friendly and end with him threatening to murder your children all without ever changing the tone of his voice. However, when too many things go wrong for him the entire act goes straight out of the window.
- Impaled with Extreme Prejudice: Diana forces Bonaparte's ally Renard to stab him to death with a sword after Bonaparte choked the location of Nick's safehouse out of Adalind, and threatening either of Diana's parents is a big no-no.
- Lack of Empathy: Bonaparte doesnt even pretend to possess a single drop. Not just towards humans but also towards other Wesen, including his own loyal followers. When Diana kills Rachael, his only response is to be impressed she was able to at such a young age.
- Neck Lift: Can choke his opponents without touching them, similar to Darth Vader. It is shown to be extremely painful, as shown when he uses it on Meisner.
- Red Eyes, Take Warning: His eyes turn red when woged.
- Sadist: He seems to take pleasure in hurting others, as shown by his Slasher Smile while choking Meisner.
- Slasher Smile: His woged form has this as a default expression.
- Soft-Spoken Sadist: Rarely raises his voice.
- Taken for Granite: Does this to Adalind to force her to comply more with Black Claw.
- Torture Technician: Bonaparte uses his vast magical powers for amongst other things, torturing people for information. When searching for the volume of Grimms lineage, he tortures Nick for its location with a combination of extreme physical pain and nightmarish hallucinations of his son for its location.
- Villain Respect: Acknowledges he underestimated Nick, after Nick singlehandedly kills Conrads entire army, before immediately trying to kill him himself.
- Virtue Is Weakness: Dismisses Renards mercy towards Meisner as weak and a danger to their cause.
- Wizard Duel: Gets into one with Eve at the Northern Precinct. He wins.
- Would Hurt a Child: Threatens Adalind with the phrase "There is no word for a parent who loses their child".
A Lowen media relations director for Andrew Dixion's mayor campaign. She is secretly a Black Claw agent.
- Cats Are Mean: Rachel is a Lowen, and likewise a firm supporter of Black Claws agenda.
- Dies Wide Open: Found by Renard like this inside her bedding.
- Evil Redhead: Rachel is a murderer, conspirator and a Wesen supremacist who also has long red hair.
- Character Death: At the hands of Diana.
- Cruel and Unusual Death: Diana kills her, by having her own bedding slowly wrap around her, until it covers her whole body and suffocates her; with Rachel awake and begging for her life the whole time.
- Dark Chick: She fulfils this role for Black Claw operations in Portland, and especially for Conrad Bonaparte.
- Fantastic Racism: Just like other members of Black Claw, Rachel sees Wesen as the Master Race, and believes they should rule the world.
- Girl Friday: Subverted, she appears to be this to Andrew Dixon and later Sean Renard, being their media relations agent. However, she is truly loyal to Black Claw, and directly involved in Dixons murder.
- Smug Snake: She greatly underestimates the danger she is in from Diana, right up till she kills her.
- The Vamp: Rachel starts a relationship with Renard to help convince him to join Black Claw. Potentially Subverted, as its implied she genuinely did have some feelings for him but valued the organisations agenda over them.
A Steinadler who was once engaged to Marie Kessler. He shows up in "Three Coins in a Fuchsbau" seeking the titular coins.
- Ambiguously Evil: It's hard to tell which side of the fence this guy is really on.
- Unreliable Narrator: There's very good reason to think that he's on the level about the things he tells Nick. But then all that gets thrown in doubt when it comes out he wanted the coins for himself all along.
- Though we can now at least be reasonably sure that he wasn't directly involved in the deaths of Nick's parents.
A Schakal hunting for the Coins of Zakynthos at the behest of the the Dragon's Tongue, a Japanese Wesen organization. He is responsible for the death of Nick's parents.
- Facial Markings: He has a vaguely snowflake-like Norse tattoo on his temple that is supposed to signify invincibility. He's not actually invincible, but it does make him more recognizable.
- The Worf Effect: Inflicts this on several characters only to fall prey to it himself. Upon arriving in Portland he murders several bystanders, then succeeds in taking Renard prisoner after ambushing him in his home. He then gives Nick the fight of his life, only to be speedily dispatched when Momma Grimm arrives on the scene. He's then taken to the precinct, where Renard poisons his lunch, causing him to unceremoniously choke to death.
A detective from Albuquerque (and also a Balam) who lost her nephew to the mysterious La Llorona and has spent years tracking his killer, before tracing the woman to Portland.
- Berserk Button: The loss of her nephew was a sensitive issue on its own, but the implication that she might be affiliated with the abductor made Valentina visibly lose her temper.
- Cat Folk: In her Wesen state, Valentina looks like a blue-furred jaguar.
- Determinator: She has spent years tracking a mysterious killer who defies everything even she knows about the world.
- "Get out of Jail Free" Card: She was briefly arrested for lying about her current status, but after Nick and Hank basically break her out to help them with La Llorona, once the three return with the missing children Renard confirms that all charges will be dropped since she was of vital help in the case.
- Jerk with a Heart of Gold: Valentina can be stubborn and get extremely focused on her goal, but in the final confrontation she prioritises saving the latest children over trying to punish her nephews killer.
- String Theory: She has a wall of this in her apartment.
A wesen who is coveted by Royals, Resistance, and Grimms alike. She demonstrated incredible powers even shortly after birth. This is but one reason she is coveted.
- Berserk Button: Diana is hell-bent on having her biological parents Adalind and Sean Renard together, and anybody who even gets in the way, much less threatens the life of one of them, will find out how her powers work lethally. She kills Renard's mistress/confidant Rachel for sleeping with him and then forces daddy to kill Big Bad Bonaparte after he choked Adalind to find Nick.
- BrotherSister Team: Diana has become the wesen in a Grimm/wesen team with her brother Kelly in the Distant Finale at the end of the series finale.
- Bullying a Dragon: In "Blind Love", a disgruntled lieutenant who was promised a promotion to captain kidnaps her to get back at Renard. Before long, he's beaten to a bloody pulp and begging Renard to come and retrieve her and put him out of his misery.
- The Chosen One: Implied to be this at the end of Revelation. Monroe's father talks about how Wildesheer supposedly only appear as an important sign of things to come. We then cut immediately to Adalind giving birth to her.
- Creepy Child: When she is an adolescent, she can communicate telepathically, project scary eyes, force her mother and father, who are no longer on good terms with each other, to kiss via voodoo dolls, and kill people by wrapping them in bedsheets like a mummy or telepathically making her biological father (Sean Renard) stab them without his consent.
- Dark Messiah: But considering Monroe's father said it was a sign of something bad coming, the baby could be this as well.
- Enfant Terrible: An example of this, if her impressive powers at such an early age are anything to go by. It only becomes clearer when she appears as a pre-teen in Seasons 5 & 6, where she is very powerful but also now willing to kill anyone who gets in the way of her parents being together. To her credit though, a lot of her more troubling behaviors can be attributed to being mentally 2-ish in the body of an 8-ish year old with the powers of a god, rather than any innate evilness...probably
- Mama's Baby, Papa's Maybe: Due to Adalind sleeping with both Eric and Sean Renard, the baby's definitely a Royal, the only question is who her father is and how close her connection to the throne is.
- Pay Evilunto Evil: Frequently does this. She's killed 2 members of Black Claw, and tortured a cop who kidnapped her.
- Soap Opera Rapid Aging Syndrome: Invoked. By the end of the fourth season, she's less than a year old but already big enough to walk around on her own. Lampshaded by The King when he first meets her.
- Justified in that the ritual Adalind went through while pregnant with her is said to have sped up her aging process along with increasing her Hexenbiest powers.
- Red Eyes, Take Warning: Her eyes glow purple when her powers activate.
- Shipper on Deck: In an...unusual sense. For example, using her voodoo dolls to force Renard and Adalind to kiss. She eventually kills Rachel, Renard's current girlfriend, to get her out of the way.
- Spoiled Brat: Diana constantly demands that things go her way, disobeying adults when it suits. It's safe to assume that with her powerful magic, as well as doting guardians, that she is used to getting what she wants.
- Story-Breaker Power: She's bar none the most powerful character in the series. Aside from the usual set of Hexenbiest powers (which were starting to blossom in utero), she can also use voodoo dolls, mimic voices, foresee people's deaths, project her image to people from far away...and that's just a fraction of what she can do.
- Walking Spoiler: Knowing about her existence spoils much of the third season on, as she becomes the second primary Macguffin of the show alongside Nick's key (the latter of which is replaced with a magic stick when it's used in the 100th episode).
- You Are the Translated Foreign Word: The Shaphat, which roughly translates to "child bride." Zerstorer is seeking out Diana for the purpose of taking her as a bride and bearing a hundred children with her.
Captain Renard's mother. Referenced several times in the first three seasons, she finally appears in Season 4.
- Blood Magic: Uses an impressive spell to transfer her blood to her son seconds after his death to bring him back to life.
- The Chessmaster: Although we haven't seen her run her own game (yet), she effortlessly deduces most of the relevant plot points involving Adalind's actions and Diana's situation. Basically, she's the polar opposite of Adalind in this regard, highly observant and thinking things through before acting.
- Defector from Decadence: At some point in her past, she was involved with the royal family and the lover of the King, but fled from them after the birth of Sean (and the King's wife tried to kill her and Sean). Now, Elizabeth just wants them to leave her and her son alone.
- Glamour Failure: Deliberately, once Rosalee realizes she's impersonating Adalind she drops the act and it briefly sounds like Adalind has an English accent.
- Good Counterpart: To Adalind and Catherine Schade. While Monroe is uneasy around her, so far she's been nothing but helpful to the heroes and cares about her son.
- Hair of Gold: In further contrast to Adalind and Catherine.
- Hell-Bent for Leather: Always seems to wear a stylish leather jacket.
- Hot Witch: As acknowledged inverse, she's really good for her age.
- My Species Doth Protest Too Much: Seems to be the only Hexenbiest shown so far that isn't an utterly self-centered asshole that blames everyone else for her own mistakes.
- Nice Job Breaking It, Hero!: Brought Renard back to life with a spell and helped Nick regain his Grimm powers by having Juliette undergo the hat ritual. Unfortunately, both of these plans backfired horribly: Renard got possessed by Jack the Ripper, who followed him from the afterlife, while Juliette turned into a Hexenbiest as a result of the ritual and betrayed Nick to work for the Royals.
- Older Than They Look: She looks to be at most the same age as her son, though she's obviously not.
- Playing Gertrude: Probably because her actress is only 3 years older than the actor who plays her son.
- Shadow Archetype: To Kelly Burkhardt. Both are mothers who are mentor figures to their sons and like to wear black but the similarities mostly end there. Both were driven into exile when their sons were young children but Kelly abandoned her son so that he could have a normal life where Elizabeth took hers with her. Elizabeth is blonde and young-looking where Kelly is brunette and old-looking. Elizabeth appears to be the best magic-user in the series where Kelly is the best fighter, etc.
- Showing Off the New Body: Briefly, after using a potion to transform into Adalind, she uses one of Monroe's shirts as a makeshift blouse. She mockingly jokes that she inexplicably felt a little slutty after turning into her, before sheepishly noting that that was probably a bit of a rough thing to say about the mother of her grandchild.
- Silver Vixen: Thanks to Diana, she's a grandmother, but she definitely doesn't look it.
- Supernaturally Young Parent: The Captain was born in 1970, which should put her somewhere in her early 60s at the youngest. Instead, some think she looks younger than her son. This is achieved through magic.
- Time Master: Briefly time-freezes the medical staff (or possibly just petrifies them for a few seconds) in order to get close enough to save Sean with Blood Magic.
- Vain Sorceress: If her son's comments about "having some work done" were serious.
Kelly Schade BurkhardtThe son of Nick and Adalind; born during the end of Season 5's premiere.
- Big, Screwed-Up Family: In addition to having one half of the family tree being Grimms and the other half Hexenbiests, his parents were mortal enemies until Adalind turned to Nick for protection from the Royals and Juliette, so the living arrangement is awkward to say the least; and his half-sister Diana is a powerful Wesen who may or may not be a Dark Messiah.
- His paternal grandmother, whom he was named after by his mother, killed his maternal grandmother.
- BrotherSister Team: When he and Diana reach adulthood, they start working together to keep the evil Wesen at bay.
- Dead Guy Junior: Named after his grandmother Kelly Burkhardt.
- Morality Pet: For both his parents- Adalind just wants to raise him right and wishes to permanently get rid of her powers to do so, and according to the interviews, Kelly is the one thing that is keeping Nick from going off the deep end now that both Juliette and his mother are dead. Well Juliette's not dead, per se, but she's not the same anymore.
