[[caption-width-right:300:Exactly what it says, folks.]]

''Grimm'' is a [[CopsAndDetectives detective series]] with significant {{Fantasy| Series}} and {{Horror| Series}} elements.

Nick Burkhardt, a new on the beat homicide police detective with the Portland Police Bureau in Oregon, is about to propose to the woman of his dreams. He comes home to discover his Aunt Marie has turned up unexpectedly. They take a walk and she hits him with the truth she's been keeping secret from him: he is one of the last descendants of the Grimm family -- as in Creator/TheBrothersGrimm -- and as such, is gifted with the ability to see monsters, or "Wesen", walking among us, and that his family has hunted and slain these monsters for generations.

Now Nick must cope with his new abilities, the knowledge that comes with them, and still do his job as a police officer.

Over the course of the first season, the series has moved away from MonstersOfTheWeek and PoliceProcedural elements wrapped up in self-contained episodes into a more of a ongoing drama with various subplots all running concurrently that happens to be centered around police work and Wesen life. At the same time, the show has branched off from focusing on Nick as the central character into more of a ensemble feel by giving other characters more screen time and involvement in various plots.

There was a web series to hold fans over during the off season (winter hiatus 2012-2013). They deal with the misadventures of Monroe helping Rosalee in the spice shop. Another web series was posted between Season 2 and Season 3 showing Bud the Eisbiber having to deal with a problem of his own.

NBC ordered a fourth season in March, 2014.

----
!! Provides Examples Of:
[[foldercontrol]]

[[folder:Tropes A-D]]
* ActingUnnatural: After realizing Juliette's friend Alicia, who is staying with them while hiding from her abusive husband, is a fuchsbau, Juliette and Nick both decide to say nothing and "act natural" to avoid frightening her with the fact that Nick is a Grimm. Despite being perfectly capable of feigning normalcy on their own, their idea of acting normal together is to stop what they are doing, plaster on benign smiles, and stare silently at Alicia.
* AdaptiveAbility: Nick seems to have this to some degree and presumably other Grimms do as well. After being blinded he [[DisabilitySuperpower develops super-hearing]] and after being zombified he develops a super-efficient metabolism. Nick's increasing strength, speed and resistance over the course of the series probably also derive from this.
* AdultFear:
** La Llorona: a ghost/wesen ''thing'' who kidnaps children and then proceeds to drown them every year on Halloween.
** Blutbaden. The first episode has one who kidnaps a little girl wearing red and hides her in his home, planning on fattening her up and later eating her. According to Monroe, this is common.
** See RapeAsDrama
** The Graussen: Your child becomes afflicted with something that makes them unpredictably violent and seemingly monstrous and there's nothing anybody can do to identify or cure it.
** TheKrampus: An evil Santa that kidnaps naughty children, hangs them in baskets from the highest tree in the area, and then [[spoiler: eats them alive]]. (This may also be wish fulfillment; anyone who is or has ever been a high school or middle school teacher can think of more than a few teenagers he'd gladly turn over to Krampus.)
** Your spouse [[DomesticAbuse hits you]] and you leave him, only for him to start pursuing you. Besides which, you know he really is a literal monster and you can't tell your friends because you don't know that they'd believe you (or that one of them is a Grimm).
** Just the Aswangs. [[spoiler: Especially if you're a pregnant woman. Some creature comes in the middle of the night, drugs you so you can't stop them, and ''devours your unborn child.'' Bonus points in the case in "Mommy Dearest" for the perpetrator being the pregnant woman's ''mother-in-law''.]]
* AggressiveNegotiations: Nick invokes this with Adalind.
-->'''Nick''': Adalind, I think it's time we settled our differences. Violently.
* AlienCatnip: There's a mold that’s poisonous to us humans, but “meth plus helium” to wesen.
* AllGirlsWantBadBoys: In "The Thing With the Feathers" it's mentioned that Klaustreich are very popular with women, but it [[DestructiveRomance never turns out well]] because most of them are [[JerkAss colossal douchenozzles]].
* AllMythsAreTrue: While the wesen have inspired various myths, it's not yet been confirmed or denied if the myths themselves are true.
** In particular, the gods of ancient Egypt were wesen who lived openly among them. Monroe refers to them as "rock stars."
* AlmostKiss: In "Quill," Monroe and Rosalee go on a picnic, talk briefly about relationships and not rushing things, [[HeldGaze look into each other's eyes]] and lean in...and then a Yellow Plague infectee stumbles into the clearing and attacks them.
* AlwaysChaoticEvil: Averted. Some wesen have more violent instincts than others, but all of them are perfectly capable of living ([[BlessedWithSuck somewhat]]) ordinary, moral, law-abiding lives if they try. Even the species with bad reputations often have relatively decent people mixed in.
* AmazinglyEmbarrassingParents: Monroe's nosy parents, especially his dad, who upon finding out Monroe has a girlfriend thinks nothing of tactlessly interrogating him about how old she is and how much money she makes. They are also quite old-fashioned. It then gets PlayedForDrama when [[spoiler: they turn out to be conservative about different kinds of Wesen mixing]]
* AmnesiacLover: [[spoiler:Juliette for a large portion of season 2.]]
* AmoralAttorney: The Ziegevolk lawyer in "One Angry Fuchsbau" uses his abilities to manipulate the witness and jury.
* AncientConspiracy: Marie warns Nick of a secret organization dedicated to defeating the Grimms and their allies (known as the "Grimm Reapers", of course). Season two introduces not just one but several others in a more realistic situation of a number of organizations all with their own particular interests. You have the Grim Reapers, but you also have the Verrat, the Seven Royal Families, the Grimms themselves (loosely organized at best), the Resistance, the Dragon Tongue, and the Wesen Council. And then whatever side Renard's on who, if nothing else, seems to be playing all sides.
* AndroclesLion: ''Last Grimm Standing'' seems to be setting up a situation similar to the aesop after Monroe helps pull a nail from the hand of a gladiator shortly before they are set to fight each other. But the gladiator shows no compunction about killing Monroe and probably would have done so had it not been for Nick's intervention.
* AnimalMotifs: Every Wesen seen so far has had one except for Hexenbiests (eyeless hag-like creatures), Siegbarstes (ogres), Hässlichen (Grimm reapers and/or trolls), Wildermanner (bigfoot), Wendigo ("savage human-like" according to Grimm wiki), Fuchsteufelwilder (imp/goblin), Glühenvolk (alien), Musai (fairy, technically Leannán Sidhe), Koschie (a [[PowerGlows radioactive]] skeleton with some flesh), and well, if you consider the Dämonfeuer as based on dragons that are not really animals but mythical creatures.
* AntiHero: Each of the main protagonists (Nick, Hank, Monroe, and possibly Renard) has racked up a considerable body count, and none of them are hesitant to use lethal force when the situation demands it. Justified though in that three of those four are cops and often deal with violent criminals. While force is not their first option, they will use it to protect others or themselves.
* AntiVillain: [[spoiler:Marty Burgess]], arguably, given that he's a SerialKiller with a very good FreudianExcuse who only kills [[JerkAss assholes]]. Although your mileage may vary on that. The people he killed may have been assholes, but they didn't seem to be in any way evil. And he was terrorizing the girl he loved at the end in a big way. Also he killed people when they saw him as harmless and were about to let him go.
** Captain Renard, who protects Nick, even though he is putting himself at risk to do so, but is looking to take the key entrusted to Nick by Aunt Marie.
** Lena, a Spinnetod (spider Wesen) who has to consume the liquefied organs of three men every five years in order to not undergo rapid aging, who is clearly reluctant to do it. And the men she does choose are all jerks.
** The villain (such as it is) in "The Bottle Imp". [[spoiler: It's not the father, it's the daughter. She's 9 years old and is experiencing the first aspects of her Wesen side a few years early. Though much of it seems like she can't control it, when she's not consumed by her violent tendencies, she doesn't show much remorse either.]]
** Adalind, as weird as it sounds. Since the episode ''Love Sick'', where the quote at the start implies that her evilness towards other people is due to [[spoiler: her mother's actions (and, most probably, her whole upbringing), she is revealed as Renard's LoveMartyr, and Nick gives her, for the first time, a serious reason to be angry at him. ]]
** Before Krampus, there was El Cucuy. While Krampus was about DisproportionateRetribution, El Cucuy's victims were some pretty horrible scumbags.
* AnArmAndALeg: A type 2 example in "Bears will be Bears" when Monroe was fighting the people sent to kill Marie, he literally dis-armed one of them.
* AppealToTradition: In-universe. Wesen have ancient cultures of their own and the more traditional often cling to rituals and conventions that range from charming to archaic to horrifying. Often used as a TakeThat to analogous traditions in RealLife.
* ArmorPiercingQuestion: Renard lands a pointed one in "A Dish Best Served Cold".
--> '''Renard''': Let me ask you something, Nick: what's really bothering you? [[spoiler:The fact that you killed somebody, or the fact that you killed somebody who wasn't Wesen]]?
* ArtShift: Perhaps not an art shift per se, but the show definitely [[DoingItForTheArt takes efforts]] to use color, lighting, shadow and other subtle visual elements to create a quasi-fairy tale/story book appearance within context of realistic visuals.
* AsianAndNerdy: Sgt. Wu, who [[LampshadeHanging lampshades]] the trope.
--> '''Nick''': Can you see who he texted?\\
'''Wu''': Of course I can; I'm Asian.
* AssholeVictim: The Fuchsbau Lena murders at the start of "Tarantella".
** This is the common trait of all the people killed by [[spoiler:Marty Burgess]]
** The attempted rapist Skalengeck [[spoiler:Angelina]] kills in "Over My Dead Body".
** The Klaustreich who stole Monroe's High School girlfriend and later slashed her face at the Prom. Monroe tells Nick that the police never got him, [[spoiler: but ''he'' certainly did!]]
** Not quite a victim in the same sense as above but [[spoiler: the young bully Monroe shows his GameFace in order to scare on Halloween. On the upside, the kid has the best Halloween story ever.]]
** Adrian Zayne from "The Hour of Death" is brutally tortured and killed by [[spoiler: Ryan the Grimm-wannabe intern]], but it is used to force him to confess to where he was keeping the young woman he'd kidnapped. His equally deserving partner also meets a similar but less justified end.
** The Zeigevolk Lawyer in "One Angry Fuchsbau" is essentially chemically castrated by Nick and the group, permanently removing his ability to influence juries into letting killers back onto the street. When he realises they were responsible and tries to attack them, Nick promptly arrests him and gets him thrown into the cell next to his former client.
*** It's actually worse than that. Not only does his ability not work, it actually ''backfires'' if he tries to use it, causing people to get instantly repulsed by him.
** The [[MonsterOfTheWeek wesen of the week]] in "El Cucuy" is drawn to avenge neighborhoods victimized by crime. All of this one's "victims" are violent criminals.
* AssassinOutclassin: The Reapers [[spoiler:are killed by Nick.]]
** This happens so often on Grimm that it would likely need it's own page to document it. Nick, Hank, Munro, Renard, and Meisner have each killed more than one assassin and Nick and Renard are probably each over a dozen by now.
* TheAtoner: Monroe is implied to be one for his previous Big Bad Wolf days.
* AxCrazy: The two Wesen junkies in “Island of Dreams”.
** The Wesen bankrobbers in "Natural Born Wesen".
* BadassBoast: Nick: "Next time, send your best." [[spoiler:It's sent to the leader of the Reapers, along with the heads of two of his underlings.]]
* BadassAdorable: Rosalee, Juliette and Adalind have their moments.
* BadassBookworm: Aunt Marie still fights off assassins while dying of cancer, and with knife scars on her entire body it's fair to assume that this is her typical MO. Profession: Librarian. Monroe repairs clocks, listens to obscure zither players, reads "Decline and Fall of the Roman Empire" for fun and, if push comes to shove, can rip a man's arm off.
* BadassFamily: Nick Burkhardt is the latest descendant of the Grimm family who have been hunting "storybook" monsters for generations. In "Tarantella", there's brief mention of a Grimm meeting an Asian doctor who shares their abilities so it may be that the Grimm family is simply the most well known or the name given to people like Nick.
** It's pretty much stated in "Cold Blood" that the "Grimm" name became popularized by the titular brothers. Before that, they were called "Decapitare" (i.e. "decapitators", since that's their most common method of dispatching Wesen).
* BadBoss: Prince Eric has the Baron turn one of his underlings into a zombie apparently just for the lulz of it
* BadSanta: The Krampus, based on the one from folklore which would arrive before Santa and punish naughty children. In this case, the naughty children were mostly delinquents and the punishment was [[spoiler: eating them alive]].
* BackToBackBadasses: Nick and Monroe in "Last Grimm Standing". Didn't last long when the police arrived to arrest everyone involved in the underground gladiator games.
* BarBrawl: In the season 3 premiere, [[TechnicallyLivingZombie Nick]] goes to a bar and [[CurbStompBattle beats up everyone]].
* BatmanGambit: Stefania and [[spoiler: Adalind]] set one up in "Good Night, Sweet Grimm" to eliminate [[spoiler: Frau Pech.]]
* BeCarefulWhatYouWishFor: In "Blond Ambition" Nick and Juliette both talk about [[spoiler:how hard being a Grimm has made Nick's life and by extension, Juliette's. Sure enough, by the end of the episode, Adelind has stripped Nick's powers.]]
* BeatStillMyHeart: The heart of [[spoiler: Frau Pech]] when it is taken out of [[spoiler: her]] body for a ritual.
* BedTrick: In "Blond Ambition" [[spoiler:Adalind takes on Juliette's form and sleeps with Nick. It ends up taking his Grimm powers away]].
* BeethovenWasAnAlienSpy:
** Monroe implies that several Hollywood actors are Ziegevolk. NBC's website for the show outright states that Casanova, Frank Sinatra, and JFK were.
** Monroe is pretty confident that Santa Claus is both real and not human; being a Gefrierengeber ([[BilingualBonus German]] for "freeze giver", would make him capable of living "up there". Nick doesn't elaborate for the viewers but seems to take the suggestion seriously.
** Monroe also suggests that the mouse creatures introduced in "Of Mouse and Man" are behind Disney - though he doesn't say the company name, he does his usual TakeThat on the subject by bringing up "their cartoon thing".
*** Or this could have been a more general reference to the common cartoon theme of mice outwitting and outfighting larger, stronger predatory antagonists.
** An old film reveals [[spoiler:Hitler]] was a Blutbad (wolf Wesen).
** Steinadlers are described as being involved in the military; there is even a photo of a general included in the book, probably as an example.
** Monroe states in "Big Feet" that Thoreau, Emerson, and (Edward) Abbey were [[spoiler:Wildermann.]]
** [[spoiler:Jeffery Dahmer]] was a [[ImAHumanitarian Wendigo]]
** In "Kiss of the Muse", one of Nick's books reveals that Rachel, the prostitute that Van Gogh infamously cut his ear off for, was a Musai and the source of both his inspiration and mental health problems. Even Monroe says "[[NotMakingThisUpDisclaimer I'm just reading what it says here]]".
** Rasputin was a Koschie, a Russian Wesen with healing abilities that make them notoriously hard to kill.
* BetterToDieThanBeKilled: Inverted, as Ariel Eberhart's plan for her father is for him to be honorably killed in combat rather than die of old age.
* BettyAndVeronica: Rosalee (Betty) and Angelina (Veronica) seemed to be this to Monroe, [[spoiler:although with Angelina's death, the choice seems to have been made for Monroe.]]
* BewareTheNiceOnes:
** Two examples within the Seelengut, a sheep-type creature. Typically they are meek and fearful. [[spoiler:However when they get into a mob mentality they take down a Blutbad.]] The second example is [[spoiler:the Blutbad being thrown to the mob by his accomplice, another Seelengut, who then runs off with the money she and the Blutbad embezzled.]]
** Also, Nick. He's one of the nicest Grimms out there, but he's racked up quite a bodycount of people who've tried to kill him [[spoiler: including several assassins who knew he was a Grimm]]. He also ''really'' doesn't like it when people go after his friends.
** Monroe. He's a mild-mannered clock maker who loves to eat organic. But look the wrong way at his girlfriend Rosalee...
* {{BFG}}: Among Aunt Marie's many weapons is a triple-barrel elephant gun. Its purpose is to kill Ogres. Interestingly, it's relatively realistic (the third, underslung barrel is far smaller than the other two). It still has a massive recoil, hurling [[spoiler: Monroe]] backwards and flying out of his hands when he fired it.
* BigNO: In "Law of Sacrifice" Adalind has one [[spoiler:when she realizes that her baby Diana has been taken away.]] [[UpToEleven It's so big it blows out every car window on the street.]]
* BiggerOnTheInside: In the exterior shots, the trailer looks pretty small. But during the interior shots, it's huge!
* BilingualBonus: Tagalog was used throughout "Mommy Dearest" when the episode tries to explain the background of the Aswangs.
* BindingAncientTreaty: There is a treaty between the Wesen Council and the Grimms to deal with certain situations. [[spoiler:When Nick showed scientific evidence the Graussen was not a demon or spirit, but a parasite that could be destroyed through exposing the host to extreme cold, he added that the boy infected by this was not to be touched by the Council, siting the treaty as his justification. The representative agreed and took the report back]].
* BirdsOfAFeather: Rosalee and Monroe. Rosalee is a rehabilitated drug addict who's cleaned up her act. Monroe himself is also a rehabilitated Blutbad. Both seem to have mellow subdued personalities whilst remaining fiercely loyal to their kind. They both even decorate in a warmly antique style.
* BitchInSheepsClothing: [[spoiler:Lucinda]] in "Happily Ever Aftermath" is also TheSociopath according to Spencer.
** Also the bad guy in “Good Shepherd”.
* BizarreAlienBiology: Some of the Wesen. "The Thing With Feathers" features a bird-like woman that makes a gold "stone/egg" in her neck that shatters like glass with impact.
* BlackBestFriend: Hank.
* BlackComedy: A mild one but Monroe brings up a family reunion during an episode. He goes on to mention that two cousins and a sheepdog ended up dead. Of course, no one missed the cousins.
* BlackDudeDiesFirst: "The Other Side".
* BlackEyesOfEvil: What wesen see when they look at a Grimm while woged. According to Monroe and Rosalee, the Grimm's eyes become pits of infinite darkness where the wesen nature is reflected back at the viewer. Monroe and Rosalee [[NightmareFuel get uncomfortable just talking about it.]] Sunglasses block the effect.
* BladeBelowTheShoulder: The vambrace Nick uses against the Gelumcaedus has a spring-loaded blade that pops up in a clear ShoutOut to ''AssassinsCreed''. Some of Nick's moves (e.g. rolling over a bent-over enemy to strike another) are also eerily similar to those made by Assassins.
* BlessedWithSuck: Various wesen are usually this and/or CursedWithAwesome, depending on which group they come from and how much they're capable of controlling/how much they indulge their more monstrous instincts and traditions.
** Spinnetods. Spider-like beings who are super-strong, super-agile and capable of regenerating any severed limb or appendage. Oh, and they must feed on three human or Wesen males every five years, or they suffer massive rapid-aging. Charlotte, a Spinnetod who refuses to feed, appears to be around seventy years old, when in fact, she's actually ''twenty-six''. The two mature female Spinnetods we see seem very reluctant to perform their kills--while being required to kill in one of the most grotesque ways we've seen all season.
* BlindIdiotTranslation: Much pain and unintended hilarity for [[GermanLanguage German speakers]]. Starts with simple grammar fail like using adjectives as nouns or wrongly cobbled-together compound words, and ends with completely nonsensical/unintelligible words or horrible dictionary slips (e.g. the supposed 'bee queen' is called "bee gay [person]").
** Monroe tries to speak German a few times. Although what he says is comprehensible, he uses weird forms, and his grammar is over the place. This leads to a little FridgeBrilliance when he translates German: It is hard to say something in a language you don't know too well, but translating from that language to a language that you DO know well is considerably easier. "Mr. Sandman" has a good example of him struggling with a wesen name he hasn't encountered before but otherwise able to translate the rest into English.
*** It's also been established that Monroe is at least a second or third generation immigrant which leads to TruthInTelevision as infrequent use of non-English languages outside the household can dramatically diminish the opportunity to practice those languages.
* BloodKnight: Manticores have a tendency to become soldiers in any era they live in. They are strong, dangerous warriors and with lacking any fear of death, makes them all the more dangerous.
** The Taureus-Armenta are stubborn, bullheaded (literally) Wesen who are on the front lines of every major battle. Like Mantirocres, they are not afraid to die.
* BloodMagic: Just so you're sure she’s evil, Adalind is shown using this in a cookie of all things.
** An example of this being used for good is when [[spoiler: Rosalee uses some of Nick's blood to break the [[LovePotion infatuation]] between Juliet and Renard.]]
* BloodyMurder: [[spoiler:The blood of a Grimm is poisonous to Hexenbiests. This is an odd case though, seeing as it doesn’t so much kill the victim so much as it kills their power.]]
* BlueAndOrangeMorality: A borderline case. While Wesen typically do a good job of masking their presence by living according to human society's rules, many of them have deeply ingrained instincts and traditions which are at odds with human laws. This sometimes crosses over with simple GrayAndGrayMorality.
* BodyguardBetrayal: Averted. When the cops were no longer watching Marie, Nick asked Monroe to keep an eye on Marie, despite knowing Monroe's dislike, hatred, and fear of Marie for what she and the previous Grimms did to his kind and other Wesen. When pointing this out to Nick, Nick replies Monroe is the only person Nick can trust with this. So despite his deep anger at the old woman and the fact that he could have tried to kill her in the hospital bed, he did keep his word to protect her from two thugs.
* BodyHorror:
** The murders in "Beeware." Being injected with fifty milligrams of bee venom does ''not'' make for a pretty corpse. Also, the [[GameFace half-transformed creatures]] often aren't nice looking.
** Sgt. Wu eats some cookies that weren't meant for him...and his face breaks out in huge boils. Even worse are his hallucinations, where he sees Nick, Monroe, and Rosalee's faces melt off.
** In general, the show seems to delight in doing this. Deaths tend to be very unpretty, and some of the things they face are equally so.
* BookEnds: The pilot episode begins with a victim listening to "Sweet Dreams" by the Eurythmics before being killed. The ending of the episode has [[spoiler: Nick stopping Adalind from killing Aunt Marie, but being injected by the needle's contents meant for his aunt. As he falls unconscious, he sees Adalind's hag face as she escapes]], with MarilynManson's cover of "Sweet Dreams" playing.
* BoomerangBigot: [[spoiler: Ryan the intern is revealed to be a wannabe Grimm who worships Nick and believes all Wesen must be destroyed. He himself is a Lebensauger, a lamphrey-like Wesen. Justified as Lebensauger are said to suffer from intense self-loathing and are shunned by other Wesen due to their "[[AllOfTheOtherReindeer hideous appearance]]", causing them to adopt other personas]].
* BrainwashedAndCrazy: Hank falls victim to this [[spoiler:thanks to evil mind control cookies from Adalind.]]
** The ''Coins of Zakynthos'' do this, giving the person who holds them delusions of grandeur, charismatic influence over others and an obsessive need to possess them. They are explicitly mentioned as being the reason for it the rise of several tyrannical Roman Emperors as well as [[{{Ghostapo}} the Third Reich]]. We even get a glimpse of this in action when Hank and Renard briefly come into contact with them and begin PuttingOnTheReich.
** Also the power of a frog-eating Ziegvolk can have this effect on people, especially women. So far we haven’t seen anyone do anything violent at a Ziegvolk's request, but they were certainly doing things they never would have done otherwise.
* BreakingTheFourthWall: See {{Cliffhanger}} below.
* BringMyBrownPants: Monroe mentions that some wesen would attempt this on non-wesen during Halloween. No prize for guessing how they might try to accomplish that.
* BrokenMasquerade: As of "Bad Moon Rising" [[spoiler: Hank]] is in on the secret. [[spoiler: It's a relief to him.]]
** Almost happens in "Natural Born Wesen". The Wesen Council is... not pleased.
** As of "The Waking Dead" [[spoiler: Juliette figures it out and takes it rather well.]]
* BroughtDownToNormal: [[spoiler:Apparently a Grimm’s blood has the power to do this to Hexenbiest, turning them completely human. Adalind ends up learning this the hard way.]]
** [[spoiler:This happened to Nick at the Season 3 finale, courtesy of Adalind.]]
* BuddyCopShow: Twice over, no less. Hank is Nick's partner on the muggle side, while Monroe helps with the creature stuff.
** As of season two, [[spoiler: thrice over as Renard is Nick's partner on most things that the other two don't cover.]]
* BusmansHoliday: Poor Monroe. He gets up the nerve to [[spoiler: ask Rosalee out on a date]] and ends up getting sucked into crazy Grimm/Wesen business. To boot, it happens as a [[spoiler: MomentKiller just before kissing Rosalee.]] And later, when Monroe and Rosalee are talking, he gets a call from Nick which prompts Rosalee to Lampshade that if it's from Nick, it must be a life or death situation.
** Inversion, Nick's worried being best man and Grimm will ruin Monroe and Rosalie's wedding so he goes to their house and they immediately assume it's a Wesen problem.
* ButForMeItWasTuesday: Nick has to remind [[spoiler:his mother that she was the one to kill the mother of Adalind, the woman she is now protecting, a few months back. Nick's mom had forgotten about that]].
* BystanderSyndrome: Monroe tries so hard to stay out of Nick's investigations... but it seems that he just can't. [[spoiler:After "Of Mouse and Man", the Reapers basically [[NiceJobFixingItVillain reverse Monroe's stance on the matter instead of warning him off as they intended.]]]]
* CallBack: The Grimm Nick and Hank read about in "To Protect and Serve" initially though he was tracking a Wildermann.
** Monroe is seen doing Pilates in "El Cucuy", which was one of the things to which he attributed his self-control in season 1.
*** Pilar, the Hispanic lady that tells about El Cucuy is the same woman that helped Juliette during her memory trouble during "La Llorona."
** In the Season 3 episode "A Dish Served Cold", Nick notes this isn't the first time a Bauerschwein's killed Blutbad. [[note]]Season 1 episode "The Three Bad Wolves."[[/note]]
** In the season 3 finale "Blond Ambition" Monroe and Rosalee recount the events surrounding their first meeting in season 1's "Island of Dreams."
* CantGetAwayWithNuthin: Nick was warned by Adalind in "Beeware" that he needs to protect her or else his reputation will be called into question if Nick allows her to die on his watch.
* CassandraTruth: The Wesen in "Happily Ever Aftermath" confesses to being able to shatter his victims' eardrums, eyes, and nasal cavities with his [[MakeMeWannaShout sonic abilities]], causing Hank to roll his eyes and tell him that playing the crazy card is not going to get him out of a trial.
* CastingGag: SamWitwer plays a brooding, violent.....[[BeingHumanRemake werewolf]]?
* CatsAreMean: Klaustreich are alley cat-like Wesen with a reputation for being dangerous jerks.
** Of the five ([[spoiler:well, four, as one is a gene-spliced oddity]]) leonine Löwen who've appeared on the show, the males are aggressive, violent, and controlling. The lone female may be an aversion--she comes across as strong-willed and competent instead of vicious and domineering.
* ChekhovsArmoury: Aunt Marie's trailer, which packs a ''literal'' armory of the various weapons, tools, and research material she and the rest of the Grimms used in their long history of fighting monsters.
* ChekhovsGun: "Sweet Dreams" by the Eurythmics is playing on the iPod of the first victim in the pilot. Later, [[spoiler:the killer begins absentmindedly humming it front of the cops, tipping them off]]. [[MarilynManson Marilyn Manson's cover]] of the song later plays during the pilot's CliffHanger.
** Juliet asks Nick to boil some water she'd set on the stove. [[spoiler:When she gets home and finds Nick beaten by Stark the Siegbarste, she runs into the kitchen to get a weapon to defend herself and Nick, and the only thing she can get her hands on is the water that Nick had set to boil, so she scalds Stark by throwing the water over him.]]
** Occasionally a throwaway line by Monroe will be referenced later in the episode as a way to beat the creature of the week.
** In the episode "Lonelyhearts", Nick's partner is shown carefully placing a tracker on the monster of the week's car, only for it to go for a walk instead. Originally this seems to be played for laughs, but then in the end when the monster tries to escape by driving to another state, as he has every other time he is close to being caught, they can track him.
** Rosalee's box cutter. Just before Freddy's murderers return to the apothecary she is shown using it to sift through boxes attempting to find herbs wesen will kill to get their hands on. When one of the murderers grab her she frees herself by jamming the box cutter into his arm.
** In "Leave it to Beavers" there is a [[ChekhovsGun Chekhov's Crossbow]] that Nick uses [[spoiler:to kill a Reaper.]]
* ChekhovsGunman: The first Wesen Nick sees, Adalind, [[spoiler:is working with the forces attempting to kill off Marie, and almost succeeds at the end of the pilot]].
* ChekhovsSkill: Ariel's [[spoiler:fire breathing act which ends with her eating fire. It hints at the fact that she's actually fireproof which comes into play at the end of the episode when she fakes her death.]]
** Monroe's expertise on clocks.
** Rosalee's former experience running an apothecary shop with her parents.
** When first learning to fire a pistol Juliette is revealed to be a natural markswoman. In "Face Off" Nick knows that she wasn't shooting to kill because she would have hit what she was aiming at. Also serves as a CallBack.
* TheChosenOne: Several people believe that [[spoiler:Adalind's baby]] might be one, though for good or bad could go either way. In "Law of Sacrifice" Monroe snarks the trope name in passing.
* CircusOfFear: The Carnival Metamorphosia pretends to be one but really they're just wesen performers trying to get by, for the most part.
* CityOfAdventure: It's amazing how many Wesen there are in Portland.
* CivilianVillain: This trope is played with in the case of Monroe the Clockmaker. He is actually a fairy tale creature--a "Wesen"--of the same type as The Big Bad Wolf, but with a careful regimen of "diet, drugs, and Pilates", he has gone from a ravening beast to a mostly-regular guy leading a mostly-normal life in the 'burbs.
* {{Cliffhanger}}: Both seasons so far have ended with one.
** Season 1 ends with [[spoiler:Juliette being put in the hospital, unconscious due to a curse.]]
** The one for Season 2 really takes the cake. [[spoiler:Nick is hit with Baron Samedi's venom and the episode closes with him in the "death" phase of the poisoning, as Eric closes the coffin on him.]]
** Also, for the Season 3 Episode, ''The Wild Hunt,'' [[spoiler: Monroe and his parents just have a huge fight with Rosalee and not approving of her being a Fuschbau. A few minutes later, Nick appears to ask advice relating to the case, only for Monroe's parents freaking out that he's a Grimm!]] They prepare to fight each other and...the screen fades to black.
* CloudCuckooLandersMinder: Rosalee showed snippets of being this many times.
--->'''Monroe:''' Last family reunion, we lost 2 cousins and a sheepdog. [No one missed] the cousins... \\
'''Rosalee:''' Yeah, yeah...
* ComeWithMeIfYouWantToLive: A very mild version of this happens in “Plumed Serpent”.
* ConspicuouslyPublicAssassination: Two Wesen are killed while being perp-walked in a police station in front of TV news cameras. [[spoiler: The Wesen broke an ancient compact and their actions threatened to expose the existence of Wesen to the human public. ]] The assassination was a message that these types of actions would not be tolerated.
** It's stated at the end of the episode that such displays are necessary about once a generation to keep the other Wesen in line. Oh, and the assassin was a human hired gun.
* CoolCar: Midway through Season One, Nick and Hank switch from a Ford Crown Victoria to a Dodge Charger.
** In a subversion of sorts, Nick's daily drive is a Toyota Land Cruiser station wagon. YMMV though, as it's the cousin of the [[TopGear indestructible Hilux pickup]].
* CoolGuns: The ogre-slaying Elephant Gun in "Game Ogre". Monroe practically [[{{Squee}} squees]] over it.
* CrazyPrepared: Aunt Marie was prepared with certain rare items and weapons for any supernatural threat.
* CruelAndUnusualDeath: Which would you prefer: having a gavel crammed down your throat or dying of an ''ugly'' anaphylactic shock via bee sting overdose?
** Or being fed a corrosive substance and having your liquefied insides sucked out?
** Being sliced in half (and living for a few moments afterwards) doesn't look fun either.
* CulturedBadass: Captain Renard.
** Monroe can be called this too, given some of his hobbies.
* CuteMonsterGirl: Female Blutbaden get fangs and red eyes when they put on their {{Game Face}}s, but are otherwise much more human-looking than male Blutbaden. Same applies when we see a female Fuschbau. Hexenbeistes, on the other hand, not so much. YMMV on Mellifers, Spinnetods, and Daemonfeuer.
** Special mention goes to Rosalee, who is by far the cutest female Wesen seen.
*** Bree Turner, the actress who portrays Rosalee, is recognized for her big BrownEyes.
** Angelina fit the bill too, being very tough, but very cute, and very easy to underestimate. [[spoiler:Her return was one CMOA after another, until she was unfortunately shot and killed]].
** Averted in [[spoiler:"Happily Ever Aftermath"]] so that [[spoiler:you can't tell which one is the murderer.]]
* TheCutie: Elly the Naiad. Also a
** CuteMute: Elly is practically this as she is deaf.
* CycleOfRevenge: This is depicted and discussed A LOT. Related to FeudingFamilies below.
* {{Convection Schmonvection}}: When Nick fights a Daemonfeuer, he grabs a sheet of copper to shield himself from the flames... and somehow doesn't get his fingers scorched off by the superheated metal.
** Soundly averted with the titular MagmaMan in "Volcanis."
* DamselOutOfDistress: In "Plumed Serpent" Juliette is kidnapped by Ariel and she makes her escape by kicking and punching her. That instance is a DownPlayedTrope because she required someone else to [[BoundAndGagged untie her hands]].
* DarkActionGirl: Angelina and Adalind
* DarkAndTroubledPast: Rosalee's led her into drug use and hanging with the wrong crowd. It also left her with a working knowledge of wesen street gangs in Portland and Seattle.
* DarkFantasy:
** UrbanFantasy: It is set in a major US city.
* DatingWhatDaddyHates: Traditional wesen do not approve of interspecies relationships. [[spoiler:Specifically, Monroe's parents ''do not'' approve when they learn that Rosalee is a fuchsbau and that they're living together. Made worse by the fact that they only met her and found out after Monroe proposed to her.]]
* ADayInTheLimelight: "Nameless" is this for Sergeant Wu, who puts his college education in English Literature and online gaming to good use.
** A better example is "Mommy Dearest", the potential victim is Wu's friend from the Phillipines, he recognises the Wesen and helps defeat it by being on scene and a good distraction. Also we finally learn his name.
* DeadpanSnarker: It's quickly becoming a WorldOfSnark.
** Monroe, the first creature Nick suspects of attacking girls in the woods. He ends up helping Nick find the actual creature in question, another of his kind.
** Nick does so a little bit near the end of the second episode.
--->'''Frank Rabe''': It isn't easy to give up your history. You haven't had to give up yours.\\
'''Nick''': Yeah, it's been lots of fun.
** Captain Renard gets a chance too.
--->'''Caller''': Did you get your present?\\
'''Renard''': Where should I send a thank-you note?
** Sergeant Wu gets one in most of his appearances, like in ''The Bottle Imp'':
--->'''Wu:''' I miss the old days when people just shot, stabbed and strangled each other.\\
'''Hank:''' Why, what happened here?\\
'''Wu:''' [[LudicrousGibs None of the above.]]
* ADeathInTheLimelight: Oh, [[spoiler:''Angelina'']].
--->[[spoiler:'''Angelina:''']] Damn.
* DestroyTheEvidence: The fact that Nick is a police detective ''and'' a Grimm occasionally puts him on the wrong side of a case, e.g. if he ends up investigating the scene of a Grimm-Wesen takedown he was involved in.
** In the Season 2 opener, Nick discreetly steals his sidearm back from such a scene. He's later seen throwing it into a river, and using his backup when the FBI demands he hand over his gun for a ballistics check against a shell casing they found at the scene. It clears him, but one of the FBI agents investigating clearly says that something doesn't add up.
** Renard swaps out his cell phone's memory card for a blank, effectively destroying the phone's evidence, after he lost it [[spoiler: when he killed representatives of the Royal Families sent to force him to ''immediately'' acquire Nick's family's key]] and it was taken as evidence.
** [[spoiler:Angelina]] tries this after murdering a guy who was trying to rape [[spoiler:her]]. Unfortunately for her, the guy was a Skalengeck who'd just been hired to do a certain job ([[spoiler:kill Monroe]]) and his friends aren't far behind.
** After fighting [[spoiler:kill four Verrat footsoldiers]] in the Season 2 mid-finale, Nick and Monroe rob them of all wallets and ID. This doesn't sit well with Monroe, but it does help a little that about the only identification the police can go on are their Verrat tattoos.
** At the start of Season 3, Renard steals the hard drive from "Tippy Canoe"'s surveillance system, to hide Nick's involvement in the bar fight.
* DestructiveRomance: Monroe and Angelina's relationship was depicted as this in episode six of season 1 with her presence pushing him to fall off the wagon.
* DestructoNookie: Subverted with [[spoiler: Juliette and Renard]]. It looks like they're going this way, then they start fighting, then they start going for it again...[[spoiler: until she empties her handgun at the walls and ceiling around him and he runs out before the cops come.]]
* [[spoiler:DidNotDieThatWay]]: Nick discovers that his parents' car crash 15(ish) years prior [[spoiler:wasn't an accident, but rather an assassination]]. He also later finds out that [[spoiler:his mother is still alive]].
* DidNotSeeThatComing:
** Most wesen when they first meet Nick and realize he is a Grimm have between this and terrified reaction. Bonus points for it being worse when they also realize he's a cop.
** In "El Cucuy," we get an example when ''both'' Nick and [[MonsterOfTheWeek the culprit]] get this. [[spoiler: El Cucuy is shocked to see the nice cop she just met is a Grimm. And Nick is shocked to find out the sweet old lady he was bringing in to question is a SerialKillerKiller.]]
** The representative of the Wesen Council [[spoiler:didn't see Nick giving him scientific evidence about the Graussen, and then releasing him from being questioned. When he returns and reports to a leader in the council about Nick and his actions, both agree he is something new and should be watched]].
* DidWeJustHaveTeaWithCthulhu: Most Wesen have this reaction to meeting [[TheDreaded Nick]]. Monroe and Rosalee have it to meeting [[spoiler:Nick's mom.]]
* DisabilitySuperpower: When Nick was blinded by a Wesen attack in Season 2, his other senses compensate by being ramped up several levels. The upgrade stays with him even after he's cured.
** While not a clear example, being temporarily zombified by Baron Samedi allows Nick to have a much greater control over his metabolism. This is shown when he goes for a vigorous jog, and Juliette notes that he hasn't even broken a sweat.
* DoesThisRemindYouOfAnything:
** In "Three Bad Wolves", Monroe's ex-girlfriend suggests that Monroe let his wild side out and [[TheAlcoholic offers him a drink.]]
** When Nick tries to explain Wesen and Grimms to [[spoiler:Julliette]] he sounds like a rabid fan trying to explain his favorite TV show to someone who never watched the show and is not a fan of the genre. He gets bogged down explaining small details and fails to realize that the other person does not have the same enthusiasm as he is not convinced of the basic premise. Naturally by the end the other person thinks that he has gone off his rocker.
* TheDogBitesBack:
** Or rather, the mouse bites back--with some fairly disturbing results.
** Or rather "herd" when a group of Seelengut (sheep-beings) go after one person with a mob mentality.
* TheDogWasTheMastermind: In "El Cucuy" the wesen of the week was[[spoiler: a 77 year old woman who changes into]] a powerful monster to hunt down evil doers. When the person is caught by Nick when he saw El Cuycuy killing the last victim, the wesen just smiled and claimed on the police record they were there to help and got blood on the clothes because of that. [[spoiler:She got away with it too]].
* DomesticAbuse: One of Juliette's friends leaves her abusive husband and comes to stay with Juliette and Nick to get away from him. [[spoiler:It turns out that the friend is a fuchsbau and her DomesticAbuser husband is a klaustreich.]] Nick tries unsuccessfully to talk the guy down over the phone:
-->'''Nick:''' I am not speaking to you as a cop ...yet.
* DomesticAbuser:
** Klaustreich tend to be irresistible to women but also have a nasty reputation of mistreating them. In "The Thing With Feathers" a klaustreich is married to a seltenvogel, bird wesen, but he keeps her a virtual prisoner and is only interested in harvesting the extremely valuable golden egg growing in her throat.
** In "One Angry Fuchsbau" Don Nidaria, a Lowen, is seen being violent and furious when his wife Katherine, a Mauzhertz, didn't wear her black dress to a party. Then [[spoiler:he kills her by throwing her off the balcony of their mansion]].
* DontGoInTheWoods: Ties into the entire mythos of Grimm fairytales that ominous activity happens in the woods. You can guess where [[CaptainObvious most of the drama happens in this show.]]
* DoubleStandardRapeFemaleOnMale: Downplayed, concerning Adalind and Hank. Hank specifically voices his belief she roofied him, and is understandably annoyed enough to not want anything else to do with her, but besides a concerned comment from Juliette no one acts like it was a big deal, and is quickly dropped without much else comment. Except that after Adalind [[spoiler: has her child taken away]] Hank is notably the only one who doesn't show an ounce of sympathy towards her.
** Adalind goes back for seconds when she poses as [[spoiler: Juliette]] to sleep with [[spoiler: Nick]] in the season 3 finale. The reaction of the characters involved still seems rather tame compared to what would be expected if the genders were reversed, including the victim shown apologizing to an unsympathetic [[spoiler: Juliette]].
* DramaticIrony: Nick and the Grimm gang have absolutely no idea that Captain Renard has a key to Nick's trailer, although the audience has known it since the middle of Season 2.
--> '''Hank:''' Do you think we should bring the Captain here?\\
'''Nick:''' ''No.''
* TheDreaded: Grimms have a nasty reputation among the supernatural species and merely being in the presence of a Grimm can cause some of the meeker ones to go into panic mode. For the Grimms that have gone up against the more nastier aspects of Wesen society such as that featured in "Organ Grinder" on a regular basis, their cynical KillEmAll mentality is perhaps justified/rationalized in their minds simply due to the infrequent instances of running into people like Hap and Monroe.
** The Grimms are even the monsters of Wesen fairytales.
--> '''Monroe''': ''You're'' the monster under the bed! [...] You're not ''real!'' You're a scary story we tell our kids! Be good or a Grimm will come and cut your head off...
** The Endezeichen Grimms are even ''worse''. They are the torture technicians of the Grimm world, who loathe Wesen with a burning passion and their entire goal is simply to KillEmAll; but not before ritually branding them and dismembering their limbs, fingers, testicles, etc. Compared to them, the Grimms who cut off heads are downright ''cuddly!''
** Furthermore, given their similar methods and outfits, it's subtly implied that the [[HeroKiller Reapers]] were created [[BeatThemAtTheirOwnGame as a reaction]] to the Endezeichen Grimms.
** The Wildsheer are dreaded among the dreaded. In Wesen fairy tales, these are the ones who kill Grimms. They are nigh-invulnerable juggernauts. According to Monroe's father, the fact the came back is a portent for a great change or evil to come.
* DueToTheDead:
** In 'Over My Dead Body" Monroe honors [[spoiler:Angelina]] in the traditional Blutbad way, which seems to involve burying the dead under a pile of rocks in the woods.
** The ''Beati Paoli'' strongly believe in this and, as wesen radicals, will attack any who desecrates tombs or steals Wesen artifacts. In "Once We Were Gods" shows their deep hatred at the ancient Egyptian pharaohs because for how to ensure the Pharaoh became one of the gods, they would torture and drug Anubis-shaped Wesen so they remained woged after death, so the form holds when they mummify them. In the end [[spoiler:Nick and Hank allow Alexander of the Wesen Council keep the stolen mummified wesen so they could give it a proper burial with a funeral pyre]].
* DyingMomentOfAwesome: Near death from cancer, Aunt Marie still manages to fight off one of the men sent to ensure she dies before talking to Nick again, and then give Nick some parting advice before she goes.
** Just before that, after Nick leaves Monroe to protect her, she senses Monroe standing over her, opens her eyes, and goads him to attack her, spitting out "Blutbad" like a curse, despite the fact that he hasn't woged in front of her yet.
[[/folder]]

[[folder:Tropes E-H]]
* EarlyInstallmentWeirdness: In the first couple of episodes Nick was a master of the SherlockScan, instantly and accurately profiling whomever he came across.
** Also, just being in sniffing distance of another blutbad is almost enough to send Monroe into a frenzy in the pilot. This weakness is never mentioned again. However, his behavior could have been chalked up to being in the direct light of a full moon. The "never go out in a full moon" weakness has been maintained throughout the series.
* EnhanceButton: Somewhat averted in "The Bottle Imp," where the police are able to zoom in on a security camera's footage of a man's car in order to get the license plate number, but both it and the man's daughter who they spot in the car, are noticeably blurry.
* EngineeredPublicConfession: More or less the finale of "A Dish Best Served Cold."
* EvenTheGuysWantHim: Almost occurs when Monroe spies on the Ziegevolk, who can generate lust-inducing pheromones, for Nick.
-->'''Monroe''': I can't be around that guy -- I almost bought him a drink!
* EverybodyLives: "Bad Moon Rising" doesn't involve anyone dying, but there is a brief scene advancing the investigation of a murder from the previous episode.
* EveryManHasHisPrice: Monroe disliked being used by Nick for tracking ... until Nick offered him a bottle of 1978 Bordeaux for helping out. Monroe had no complaints from there on.
* EveryoneHasStandards: Bart, Monroe's traditionalist father [[spoiler:for all his seeing Bauerschwein as prey, would never be happy to see his son help a Grimm hunt one down]].
* EvilCannotComprehendGood: The villains of "The Thing With Feathers" just can't get that Nick is trying to protect the Seltenvogel from them, not trying to steal her golden egg for himself.
* EvilCounterpart: Though you can't exactly call her "evil", [[FieryRedhead Angelina]] is this to [[HeroesWantRedheads Juliette.]]
** "Over My Dead Body" compares Angelina (Monroe's amoral and violent ex) to Rosalee (Monroe's current stable girlfriend)
* EvolvingCredits: the opening credits sequence for season 2 changes as more episodes air such as with the inclusion of Captain Renard's GameFace following its much-anticipated reveal during episode 2.
* ExactWords: Reginald really should have been careful of how he worded his bargain with Edgar Waltz.
--> '''Reginald''': You promise you won't hurt my family!\\
'''Edgar Waltz''': Of course not! You kept your end of the bargain. I wouldn't dream of torturing your ''family''.
* ExplainExplainOhCrap: Nick called Monroe to ask about the Yellow Plague. As Monroe explains the symptoms, [[spoiler:Rosalee is getting frisky with him.]] Monroe then realized [[spoiler:''Rosalee'' was matching the symptoms and realizes she is ill with an illness that wipes out any Wesen infected with it.]]
* {{Expy}}: DJ Retched Kat in "Danse Macabre" is one of [[http://en.wikipedia.org/wiki/Deadmau5 deadmau5]].
* EyelessFace: The hexenbiests display this trope when woged.
* EyeScream:
** A dead victim in ''Organ Grinder'' gets his eyes pecked out by a raven as he's floating down the river.
** And in "Happily Ever Aftermath" several victims get their eyeballs ruptured by the Murcialago's sonic scream. Very bloodily, at that.
** "Mr. Sandman." Holy God, "Mr. Sandman." Here the bad guy is a fly Wesen from Africa, who breathes parasite-laden sand into his victims' eyeballs, blinding them so he can lap up their tears. [[FromBadToWorse And if the parasites stay in the eye long enough, the eyes are quickly destroyed.]] We know this because the show doesn't just imply it through exposition but also has one victim tear off her bandages as the infection grows to that stage in order to show us her empty eye sockets laden with wriggling worms.
*** [[spoiler:The only way to cure the parasite infection is to take one of Andre's eyes from him - while he's in full Wesen form!]]
---->[[spoiler:'''Monroe:''' Oh Nick, dude, you don't wanna be seeing this.]]
* FairyTales: Each episode is at least partially based off of one (if not a WholePlotReference). Those that aren't are based off general folklore or creepy stories and factoids from around the world.
** The Pilot's main plot is based on "Literature/LittleRedRidingHood".
** "Bears will be Bears" is partly based on "Literature/{{Goldilocks}}".
** "Beeware" is partly based on "[[http://en.wikipedia.org/wiki/The_Queen_Bee The Queen Bee]]".
** "Lonelyhearts" is based off satyrs, with the Grimm tie-in coming from the tale of "Literature/{{Bluebeard}}" (or more specifically "[[http://en.wikipedia.org/wiki/Fitcher%27s_Bird Fitcher's Bird]]", because of [[spoiler:the monsters' abilities to induce lust in a victim through touch, and other habits]] [[spoiler:and his many wives]] (based on both the teaser quote and the name of the {{monster of the week}}).
** "Danse Macabre" is based on "Literature/ThePiedPiperOfHamelin".
** "Three Bad Wolves" is based on "Literature/TheThreeLittlePigs".
** "Let Your Hair Down" is very loosely based on "Literature/{{Rapunzel}}". Loosely in that she's a WildChild Blutbad who strangles someone in her first appearance.
** "Game Ogre" is loosely based on "Literature/JackAndTheBeanstalk".
** "Of Mouse and Man" is an aversion, since it's taken from Creator/JohnSteinbeck's book ''Literature/OfMiceAndMen''
** "Organ Grinder" is based on "Literature/HanselAndGretel".
** "Tarantella" is based on the Japanese fairytale "Jorōgumo"
** "Last Grimm Standing" is based on Androcles [[spoiler:but with the idea averted as the "lion" does not repay the kindness it was shown.]]
** "Three Coins in a Fuchsbau" has a quote from "The Master Thief".
** "Plumed Serpent" has a quote at the beginning from "The Two Brothers".
** "Leave it to Beavers" is based on "Literature/TheThreeBillyGoatsGruff".
** "Happily Ever Aftermath" is based on "Literature/{{Cinderella}}" [[spoiler:but inverted, with the stepmother and stepsisters being terrorized by the entitled, sociopathic Cinderella expy ]]or on other fairy tales where [[spoiler: there is just one evil stepsister, despite there being numerous good siblings, like, possibly The Three Princes and their Beasts]].
** "Big Feet" is about Big Foot [[spoiler:but not really. It's more like Dr. Jekyll and Mr. Hyde]], although the official website states that it was based off the story of ''Hans the Hedgehog''.
** "Nameless" is based off of Rumplestiltskin. The serial killer demands that people try to guess his named after each murder, and he's [[spoiler:doing it because he fixed the code an MMORPG designer wrote, and she stood him up on the payment date.]] After he's caught, he throws himself off a building, unable to handle the idea that he 'lost'.
** "One Night Stand" is based off of ''Literature/TheLittleMermaid'', with the Ariel expy being deaf.
* {{Fanservice}}:
** The decontamination ShowerScene between Nick, Hank and Wu in "Red Menace." There were [[FemaleGaze a few closeups.]]
** Rosalee in the carnival costume. Invoked in-universe for Monroe's benefit in their bedroom.
* FantasticRacism: This trope tends to be one of the big subtexts that courses through the show and few characters escape it.
** It's explored in an unusual amount of depth however. FantasticRacism is never used simply for a "Racism Is Bad" aesop and it is far more frequently used to focus on where racism comes from, how it is perpetuated and how it is experienced from the point of view of perpetrators and victims, as well as how those positions can be reversed.
** In "A Dish Best Served Cold", Captain Renard calls Nick out on this, as he's still feeling guilty about accidentally killing an innocent:
-->"What's really bothering you? The fact that you killed somebody, or the fact that you killed somebody who wasn't Wesen? Because God knows you've killed plenty of them. [[VanHelsingHateCrimes That's what you Grimms do]], isn't it?"
* FemmeFatale: Adalind Schade, and possibly all the Hexenbeist who are said to be lovely in human form, and are loyal servants to royalty.
* FeudingFamilies:
** The Grimms have been killing Wesen for centuries, and the families of the dead hold grudges. Monroe's grandfather was killed by a Grimm and he is afraid that he will be disowned if his family finds out that he is helping Grimms instead of killing them. Of course this is somewhat one-sided since the KillEmAll mentality many Grimms have means that while most wesen dread and hate Grimms, for many Grimms [[ButForMeItWasTuesday it was just Tuesday]].
** Some of the supernatural species really do not get along and have been fighting feuds for a long time. Bauerschwein are a major victim of Blutbad violence and in "Three Bad Wolves" one of them has had enough and kills the brothers of the Blutbad who killed the Bauerschwein's brothers. In "A Dish Best Served Cold", the chef of a restaurant intentionally prepares an appetizer that contains a mushroom that is deadly to Blutbaden, which is given to all customer.
** Other species tend to operate more on natural animal lines - the snake creature that appears in "Of Mouse and Man" suggests that they are natural predators/antagonists towards the mouse creature that also appears.
** Bridge trolls and beaverfolk don't get along too well either. In this case, it's due to mutual territory - one creates what amounts to bridges and the other likes to profit off them.
* FieryRedhead: Angelina.
* FiveManBand: One is beginning to take shape:
** TheHero: Nick
** TheLancer: Monroe for the Wesen stuff, Hank for the cop stuff
** TheSmartGuy: Rosalee and Juliette. When it comes to Wesen science Rosalee will be the one to examine things. Juliette becomes this when needing to use formal empirical sciences, Juliette uses her expertise.
** TheBigGuy: Monroe when he put his GameFace on.
** SixthRanger: Captain Renard, [[spoiler: after his Wesen nature is revealed and is cured of his obsession with Juliette]].
* FlashBack: Nick gets them to things Aunt Marie told him, and to earlier experiences with Adalind.
* FlashMob: "Beeware".
** FlashMobCoverup: One of the participants used it as a way to cover up the murders of Hexenbiests.
* FlashStep: Andre, the fly Wesen in "Mr. Sandman." He also makes a very faint buzzing sound when doing this, which only Nick with his DisabilitySuperpower can hear. The scene where this is first shown is slightly hilarious, as Andre is flash-stepping from window to window, trying to get them open, making it seem like a fly trying to get out.
* ForcefulKiss: Ariel plants one on Nick in "Plumed Serpent" after tackling him and pinning him to the ground.
** Nick himself forces a kiss on [[spoiler: Adalind to make her bite him since the blood of a Grimm can take away her Hexenbiest powers]].
* FriendshipMoment: When Monroe is beaten up in "Of Mouse and Man" for "messing with the status quo" by helping a Grimm, Nick says [[ItsNotYouItsMyEnemies he won't ask Monroe for help again]]. Monroe declares that [[NeutralNoLonger Nick can ask him for all the help Nick needs]], and they toast the moment with a beer.
-->'''Monroe:''' I've never been much of a status quo guy. And next time, we'll be ready for them.
* FrightDeathtrap: The 'Run to Your Doom' version is used in the opening of "Sweethearts". The VictimOfTheWeek is suffering terrifying hallucinations that cause her to run onto a bridge and into the path of car. She might have survived, but the Wesen shows up to finish her off.
* GallowsHumor: Oh, ''hell'' yes.
* GambitPileup: Nick is in the middle of multiple gambits by various groups in the Wesen world. The Dragon Tongue organization wants the Coins of Zakynthos. The Verrat is trying to destroy the Wesen resistance movement. The Reapers want to kill all Grimm. Renard's family want [[spoiler: the key/map Aunt Marie gave Nick]] so they can find an ancient artifact. Renard seems to have his own agenda that might not exactly match that of his relatives.
* GameFace: All Wesen can show one, though the extent of their change ('woging') and whether humans can see it depends heavily on individual master and emotional state. Wesen with greater mastery over woging can invoke a broader spectrum of change and even change some or all of themselves on demand while those with less mastery are more at the whims of their emotional state. Regardless of whether they're showing, wesen retain the many of their physical abilities such as as strength and toughness while claws and more monstrous abilities are unavailable unless they woge. Wesen also have no innate ability to detect other wesen other than seeing another wesen woge. This hasn't always turned out well for those that pick on the wrong wesen.
** Adalind and Monroe, both of whom regularly engage in non-human activities, demonstrate considerable physical ability with no transformations while the family of bears (who have suppressed their non-human natures) seem to prefer transformation for any sort of show of ability.
** Nick and the other Grimms are not shown to have telltale physical traits themselves, but can see a wesen's GameFace regardless of whether an individual wants them to or not, which is one of many reasons wesen fear Grimms. Because of the reaction Nick and other Grimms have to seeing a wesen woge, most wesen can identify them as a Grimm if they're watching someone when they woge. On the flip side, this also means that wesen can occasionally mistake someone for or not realize that someone is a Grimm.
*** "Synchronicity" finally reveals just how Wesen identify a Grimm. Monroe and Rosalee explain that upon seeing a Wesen woge, a Grimm's eyes [[BlackEyesOfEvil turn utterly, infinitely black]], and the Wesen sees its own true nature reflected back at them from those eyes--a deeply unsettling experience for the Wesen. This explains why all the Wesen Nick has encountered have failed to recognize him as a Grimm until after ''he'' recognizes ''them'' by seeing them woge.
** Non-Grimms/non-wesen can also see a wesen's GameFace if the wesen in question wants them to or they're in a high enough emotional state. However, Monroe points out that doing so is usually a bad thing if only because humans generally aren't prepared for the sudden shock to their WeirdnessCensor. Some wesen deliberately show their GameFace to their human prey in order to panic them.
** Monroe elaborates further for Hank; a normal change as a sign of recognition among wesen can't be seen by humans; an aggressive fighting mode game face is readily apparent. He demonstrates: Hank doesn't see the first change, but sees the second... and is equal parts freaked out and impressed. [[CrowningMomentofFunny And then wonderingly asks Monroe to do it again.]]
*** Also, as Hank demonstrates in later episodes of Season 2, it's possible for a normal human to build up tolerance to the GameFace. Contrast Hank's first exposure to a wesen, and how he freaked out at Carly's GameFace, to how calm and confident he is when facing the wesen in "Nameless".
** Wesen law prohibits the deliberate showing of a Wesen's GameFace to humans in a public setting for personal gain. In the past these types of deliberate provocations resulted in witch hunts and massacres of Wesen by humans. The breaking of this law is considered one of the worst transgressions a Wesen can commit against other Wesen and is punished by death.
*** This is one of the purposes of the Wesen Council, whose leader mentions once that an attempt to violate the law happens once a generation by some of the younger Wesen who consider these laws ancient and obsolete. A public display is usually engineered by the Council to scare the rest into submission.
* GenreBlind: Nick. He doesn't understand the purpose of wolfsbane or walking through water when trying to track down [[spoiler:a Big Bad Wolf in human clothing]]. That said, this is justified in he is new and used to only going after human suspects. Or not, in that he seems never to have read fairy tales or seen a horror movie. Those are also pop culture references.
* GenreBusting: Starts out as an UrbanFantasy PoliceProcedural, then gradually adds HeroicFantasy, {{Dramedy}}, SpyFiction, and a touch of Supernatural Horror.
* GenreSavvy:
** Being both trained police officers ''and'' involved in the Grimm-Wesen conflicts in general, Nick and Renard have a few moments of making sure they don't accidentally leave evidence (e.g. fingerprints) behind at a given scene. For example, when [[spoiler:discovering Aunt Marie's Grimm trailer]] in the Season 2 opener, Renard calls a Wesen locksmith rather than try to break in, wears gloves, and is careful not to disturb anything when he's looking around.
** In the Season 1 episode "Beeware", Monroe constantly compares it to a horror movie.
-->'''Monroe:''' Oh, this is usually the part in the movie where the sidekick gets it!
** Not so GenreSavvy in season 2 episode Mr. Sandman. [[spoiler: You're chasing a Wesen whose modus operandi is blinding its victims with horrible eye parasites. Let's not wear any goggles.]]
* TheGhost: The King, [[spoiler: Captain Renard's father. That is, until Season 3 episode "Nobody Knows the Trubel I've Seen" when he finally makes an appearance.]]
* {{Ghostapo}}: The coins in "Three Coins in a Fuchsbau" are stated to be responsible for this.
* GladiatorGames: The Lowen, a lion-like species of Wesen, enjoy running them to the modern day. [[spoiler:Captain Renard sanctioned the event with a list of approved targets to snatch and fight. He is not happy when they deviate from the list.]]
* GoMadFromTheRevelation: Based on Monroe's testimony and [[spoiler:Hank's freak-out upon seeing two wesen in their game faces,]] most normal humans tend to go mad from seeing a wesen in their other form as their minds cannot handle such a break from reality. A really good example can be seen in the first murder of "Happily Ever Aftermath", though in that case, the darkness and the fact that said wesen was trying to kill the victim didn't help matters.
** On the flip side, when [[spoiler: Nick is forced to reveal the truth in order to protect a young girl who just GameFace'd on Hank, Hank ultimately ends up returning to some semblance of sanity due to the affirmation that what he saw wasn't his mind going.]] In his words: "I may be crazy, but at least I'm not alone."
*** And it wasn't just any [[spoiler:girl but the daughter of an old friend of his; he has known her since she was a baby]].
** Also, thanks to some help from Monroe, Hank demonstrates it's possible to build a tolerance to the effects of the GameFace. Of course, knowing that there are threats out there, and that you can prepare yourself to fight them also helped a lot.
** Wu doesn't handle it well at all when he comes face to GameFace with an Aswang. It doesn't help that Nick and Hank know what they're up against and don't give him a heads-up, even after he recognizes the legend on his own. [[spoiler:He ends the episode having checked himself into a mental ward.]]
* GoodIsDumb: Hap is easily the nicest Blutbad encountered so far ... and also the dumbest.
* GoodIsNotSoft: Nick demonstrates this more and more as the series progresses. Monroe gets several instances of this as well.
* GratuitousForeignLanguage: The names of Wesen are usually [[GratuitousGerman German]], which is to be expected since they were discovered and classified by a pair of German authors. Some are normal pre-existing words re-applied as a monster name, while new word creations usually end as [[BlindIdiotTranslation Blind Idiot Translations]].
** Some Wesen names have roots in other languages, such as Greek.
** There's also some GratuitousFrench, as Renard talks to his cohorts/superiors in French occasionally.
** An episode in season two gives a little more context: what we would consider 'modern' Grimm stories and social structure started before the Fourth Crusade (1202–1204) and the Sack of Constantinople of 1204 plays an important part in the show's mythology. Long enough in the past to be fairly mysterious but not so long ago as to prevent much older things from existing and having been established elsewhere.
*** We also find out what the Grimms were called before the brothers made the name synonymous with "Wesen-hunter". The original name, derived from Latin, was "Decapitare" (i.e. "decapitator"), given their preferred method of killing Wesen. A few Wesen still refer to them with this term.
** The episode dealing with a Russian Wesen has a lot of GratuitousRussian, including Renard showing off his fluency in the language much to Nick and Hank's surprise. He explains that he spent some time in Moscow with his mother. The actor only shows a slight bit of accent, thanks to his parents being Russian Jewish immigrants.
* GreatBigBookOfEverything: Actually several, but whenever Nick needs information on a new Wesen, one of his ancestors has probably already archived such an encounter; Nick is currently taking up the family tradition of archiving his own experiences with various Wesen. Monroe joked that he was Nick's living "Grimm-o-pedia."
** The books are written in different languages. Nick is able to read the ones in English, but he needs Monroe's help with the German ones, and he was forced to bring the Latin book to Renard, who appears to be fluent in the language.
*** Why Aunt Marie didn't teach Nick German and Latin, or see that he took them in high school or college, is never explained.
* TheGrimReaper: Played with. In this continuity, it isn't the ''Grim'' Reaper, but Reapers of the ''Grimms'', an organization of (as-yet-unidentified) Wesen dedicated to wiping out the Grimms and who use scythes as weapons. According to TheOtherWiki the Reapers of Grimms are an organization of trolls with strong evidence from the name of the first to appear (Hulda).
* HealingHands: Koschie are a type of wesen able to cure with their hands [[spoiler:by emitting some form of radiation]] to cure anything from tumors to cuts on the face. [[spoiler:They can reverse this and kill with the same radiation]].
* HeartIsAnAwesomePower: Reinigen. Suddenly the ability to control rats with music doesn't seem so harmless anymore...
* HeldGaze: Naturally occurs between Nick and Juliet.
** Also a variation of this trope is played with between Rosalee and Monroe in "Island of Dreams". To confirm that Monroe did in fact know Freddy, Rosalee grabs onto his arm and looks him square in the eye before revealing herself to be a fuchsbau. Monroe's gaze does not falter when he reveals himself to be a blutbad.
* HeroicBystander:
** [[spoiler:[[TheNoseKnows Monroe]] helps Nick track down the rogue Blutbad and the little girl]].
** Also, [[spoiler: [[CuteBruiser Rosalee]], when she saves Monroe by using a brick to knock out a gun-wielding junkie.]]
** Once more with [[spoiler: Carly in "Bad Moon Rising"]] though played with since you'd think it was [[spoiler: her dad since he starts the fight with one of the guys holding her hostage.]]
* HeroicSacrifice:
** [[spoiler: Angelina]] in "Over My Dead Body."
** In "The Good Soldier", [[spoiler:OldSoldier Colonel Desai, dying of lung cancer, allows himself to be fatally stabbed by a private military contractor right in front of Nick and Hank. The man had participated in the rape of one of the colonel's soldiers three years previously in Iraq, but it was covered up. With evidence found elsewhere, Desai set it up to look like the [=PMC=] killed him to maintain the cover-up--because it was too late to try the criminal for the rape, and impossible to pin him for the murder of one of the other rapists, who had wanted to come forward and confess]].
* HeroKiller:
** Stark from "Game Ogre" is about as close as a one-shot character can get without actually killing anyone.
** [[spoiler:Baron Samedi, [[BadassInDistress who captures Nick]] at the end of Season Two.]]
** A Wildesheer, also known as caccia morta, is this to Grimms as well. In Monroe's childhood storybook, these were the guys who killed Grimms.
* HesDeadJim: Aunt Marie fights off another would-be assassin, then delivers LastWords to Nick: "Follow your instincts, believe nothing else" before the scene changes to Nick and his girlfriend at the cemetery.
* HiredToHuntYourself: Nick investigates homicides for a living, so on occasion he gets called in to examine the scene of his battles with wesen.
* HiveMindTestimonial: The interviews with the "flash mob" come out like this. Nick even comments on it, asking the last suspect why it sounds like there's an echo in the room. (Of course, they're bees. It IS a hive.)
* HoistByHisOwnPetard: Baron Samedi really should’ve thought things thru before [[spoiler: turning a Grimm into a zombie]]
* HollywoodHealing: Typically averted, as when Nick gets into a fight, he tends to carry about the results for a while.
* HollywoodSatanism: In one episode, the medical examiner remarks that Satanic cults of this type were popular during the 80's. (In real-life, there was a [[WitchHunt moral panic]] at the time that resulted in many innocent people tried and convicted for nonexistent "Satanic" crimes.)
* HomoeroticSubtext: "Organ Grinder" Has Nick pulling out his cell-phone, asking the person on the other end if they have plans for dinner, and smiling fondly. You'd think it's his girlfriend, right? Nope! Cut to dinner at Monroe's house, complete with white wine and jazz playing in the background. In fact, the entire ensuing conversation reeks of homoerotic subtext, with Monroe complaining about how Nick never asks about other aspects of his life, mentioning testicles and claiming that "everything works great" in regards to his private parts.
** That same episode starts with coffee at Monroe's house in the morning, with Monroe asking Nick when he was going to tell his girlfriend. He means about Wesen and Grimms, but the viewer might be forgiven in thinking that they started sleeping together.
** In "Leave it to Beavers" this happens when Juliette wants Monroe to come to dinner. Nick immediately panics trying to figure out what Monroe and he are going to say to keep the nature of their (working) "''relationship''" secret from her. The whole scene plays out like they're trying to hide an affair.
** And then in episode 12 of season two, Nick's living with Monroe. But not for this reason and it's not particularly amusing.
* HoneyTrap:
** Implied in "Cold Blooded" as the main reason why Breslau sold out Renard's safehouse in Vienna, Austria.
** In "Blond Ambition" [[spoiler:Adelind magically disguises herself to look like Juliette and lures Nick into bed, in order to affect him with a Grimm-depowering spell.]]
* HorribleCampingTrip: The couple at the beginning of "Let Your Hair Down" had no idea what was coming... and it wasn't even [[HumansAreTheRealMonsters a supernatural threat.]]
* HorrifyingTheHorror: Grimms are ''so'' well-known for hunting and killing Wesen that they scare the ''living hell'' out of the creatures on which fairytale monsters were based, to the point that Grimms are the monsters of Wesen stories. Wesen who could dismember a person with their bare hands get [[OhCrap nervous]] at the sight of Nick, not because he looks or acts threatening but because of the reputation his ancestors have earned. [[spoiler: Monroe, who is strong enough to rip a man's arm off by accident and brave enough to think crashing through a glass window in full GameFace to scare Nick is funny, is outright scared of Nick's mom.]]
* HowlOfSorrow: Monroe does this [[spoiler: over Angelina's HeroicSacrifice for his life.]]
-->'''Monroe''': No. Don't call anyone. We're doing it our way.
* HumanMomNonhumanDad: {{Inverted}} with the Naiads. The men are all infertile so the women have to mate with human men. In the olden days, males resented the fact that they have to raise the children of other men so much that a tradition sprung up of killing the human fathers. Modern naiads don't necessarily engage in the practice, but it does happen.
* HumansAreSpecial: Not in the traditional way, but wessen tread lightly around humans because if discovered, humans have the numbers and violence necessary to eradicate wessen completely. And as shown with humans who know about wesen, continual exposure all but eliminates the psychological effects of seeing a woging wesen.
* HumansByAnyOtherName: As revealed in "The Good Shepherd", Wessen call them "Kehrseite".
* HybridMonster: Though uncommon, it seems interbreeding Wesen can produce these. Monroe and Rosalee vaguely and awkwardly mention this being the possibility of the two of them having kids.
* HypercompetentSidekick: All of Nick's sidekicks/allies/helping hands, except Hank, who is often just as competent as him.
** Monroe nearly as strong as Nick [[GameFace if he goes wolfy]], which admittedly isn't his favorite thing, [[GeniusBruiser and knows way more about Wesen traditions and the supernatural than Nick does]].
** Rosalee [[TheSmartGuy knows Wesen herbalism]] (unlike Monroe), and also about Wesen history (less than Monroe) and is a somewhat capable fighter [[BewareTheNiceOnes when provoked]], while having a lot of connections with the current Wesen world, including "old world stuff".
** Juliette is not only [[TheChick a kind and diplomatic person who comforts Nick and Hank]]. She is a vet, [[ScienceHero with skills in science]] and an impressing knowledge of Spanish. [[CombatPragmatist Also, she can take down an ogre]].
*** Well if by take down you mean be smart enough to [[GenreSavvy toss a pot of boiling water (which she didn't put on) over it instead of going a kitchen knife]] which distracted and hurt it long enough for Nick to retrieve his gun and continually shoot it in to retreat.
** Renard has connections, political influence, charisma, strength, and the will (and possible evilness) necessary to say IDidWhatIHadToDo.
** Later Nicks partner Hank now in the know, is just as though as Nick, and knows some proper police procedures for them to catch Wesen.
* HystericalWoman: Averted with [[NervesOfSteel Juliette]], Rosalee the apparent EmotionlessGirl, [[TheBaroness Adalind]] who only plays the WoundedGazelleGambit occasionally, and Angelina, who is more HotBlooded than hysterical. Ariel is a borderline case of subversion. She is very emotional and out of control, but she is much stronger than she is vulnerable. This is a better track than most action shows at subverting it.
[[/folder]]

[[folder:Tropes I-N]]
* IAmNotLeftHanded: Rosalee was being held hostage and she called for help. When the help in the form of Monroe arrives, the guy asks what a Fuchsbau could do against him. Rosalee replied, “I didn’t call a Fuchsbau” - cue Blutbad attack.
* IHaveThisFriend: Bud says this almost word for word in a series of webisodes when he comes to Rosalee and Monroe for a cure for baldness. [[spoiler: Subverted when it turns out he really did have a friend, who's much worse off than he is with the uncontrollable hair growth they're both suffering]]
* IJustWantToBeNormal: Nick asked, almost immediately after realizing his abilities as a Grimm, how to stop it.
** Rosalee tells Juliette that denial and self-loathing are not uncommon among wesen coming to terms with who they are. She implies that it fueled her drug addiction and illegal activities in the past. She even calls the trope nearly by name:
-->'''Rosalee:''' ...You have no idea how badly you just want to be normal.
* INeedADrink: Monroe’s response to finding out that a hardcore Grimm might be in town, he keeps drinking a glass of red wine like it’s a life line while telling Hank and Nick about it.
** Also, in "The Three Bad Wolves", after finding out that Hap was willing to cooperate with a Grimm (and also that none of them were trying to kill each other), this was Angelina's response.
** Happens a lot to Monroe in "Season of the Hexenbiest", though the circumstances are more emotional than physical in the above cases.
** Nick and Monroe both do this in ''Face Off'', Nick after [[spoiler: seeing Renard kissing Juliette and being told they're probably under a spell]] and Monroe a bit later. They're having that kind of day--at the end of that kind of week.
** Monroe does this when he and Nick are trying to figure out how to undo the spell on Renard and Juliette. The reason he needs one is because all the twists and complications in the process pretty much involve every character in the show.
** A lighter version occurs in "Mr. Sandman" as Nick, Hank, Monroe, and Rosalee talk about Captain Renard and his... complex backstory.
** In "The Waking Dead", Juliette, Monroe, Rosalee, and Bud are unanimous on this point after [[InternalReveal events in the spice shop]].
* IfYouEverDoAnythingToHurtHer: Rosalee's sister shows her reconciliation with her sister by popping up behind Monroe in full woge and telling him that if he breaks her heart, she'll kill him.
* ImmuneToBullets: Some Wesen are highly resistant to Muggle tactics to taking them down. Nick even referenced when he tried macing a teenage Wesen who just enjoyed it.
** Having said that, as a general rule, most Wesen do not react well to handgun rounds. And when that doesn't work, there's always [[ShotgunsAreJustBetter shotguns]].
** And if you're facing a [[OurOgresAreHungrier Siegbarste]], forget the above firearms and go straight for your trusty triple-barreled elephant gun.
* ImperiledInPregnancy: One of Sgt. Wu's Filipino friends gets attacked by an aswang, which nearly kills her fetus while she was sleeping. Nick and Hank were able to resolve the situation and save her again from the monster.
* ImprovisedWeapon: [[spoiler: Nick's mom]] uses a rolled-up magazine as a baton while defending herself from the knife-wielding Catherine.
** Less improvised and more creative use of one's gifts, but Nuckelavee (a horse-like Wesen) use their hooves as clubs. As can Seelenguter, though they're less inclined towards violence.
* IncrediblyLamePun: In "The Twelve Days of Krampus" Monroe jokes that clock repairs have to be ''timely''. When Rosalee doesn't laugh, he admits that the joke was ''second hand''.
** When describing one of the holes in the wall of their home from a fight, Nick says "Crossbow, actually. But that's beside the point."
* InfantImmortality: Although the show seems to delight in showing [[AdultFear kids in terrible danger]] and seems to imply infanticide in the past, there have not been any children deaths within the show itself.
* InsistentTerminology: Zaubertrank are magic potions, but are almost always referred to as Zaubertrank. [[LampshadeHanging When Nick asks Monroe why they aren't just referred to as potions]], the answer is basically "because Zaubertrank sounds cooler".
** Weirdly not to long after this Rosalee starts calling them potions
* InstantBirthJustAddWater: The birth scene in “Endangered” is extremely quick, and there is a minimum amount of gore, but this might be Justified by the fact its technically a different species, and their biology is stated to be different on some accounts.
** Jocelyn's labor is implied to have started much earlier in the day while her and her husband are still in their vehicle. She even tells him that she needs to rest or she'll have the baby right there. Then her husband leaves her in the abandoned cabin and the Grimm gang (and the viewer) don't see her until well after dark. She could have been having continuous contractions which stepped up in intensity at that moment.
* InterspeciesRomance: While it isn't known how taboo it is, the ziegevolk in "Lonelyhearts" was able to reproduce with humans, so humans and Wesen are genetically compatible. [[spoiler:While it isn't known how human-Wesen lovers are seen, to the Old Land wesen wedding outside their species is a big no-no and will result in being hunted down and killed.]]
** Renard reveals that [[spoiler: at least for Royal and Hexenbiest, they can breed and have a kid. But said kid ends up with a GameFace that's literally half human and half Hexenbiest. That is, parts of them remain human, other parts change. At this point it is unclear if Royals are simply powerful Grimm or if they are a separate group from the Grimm.]]
** Occurs in "The Good Shepherd". [[spoiler: As a byproduct, it also reveals that yes, wesen of different types can have children together with no real issue.]]
** It is the norm for naiad women to seduce and mate with human males, as naiad men are infertile. However, it's usually the naiad men who they marry and raise the children with. Some ultra-traditional naiads follow misogynistic rituals as a result of their resentment over this.
* InvisibleToNormals: Most Wesen do their best not to be seen woging by humans, as this tends to drive them mad.
* {{Irony}}: The spinnetod in "Tarantella" ends up getting caught by Nick because she becomes entangled in a web that's over water.
* ItsNotYouItsMyEnemies: Aunt Marie's reason for being an old maid; she suggests it to Nick when she reveals the truth to him about his lineage.
** She was engaged at one point, to a Wesen no less. She broke it off, though.
* ItsAllMyFault: Monroe (mostly) and Angelina in "The Three Bad Wolves" [[spoiler:after Hap was assassinated by Orson while the two were away]].
* JoggersFindDeath: Odds are they do.
* TheJuggernaut: Wildesheer are nigh invulnerable fighters. They can take punches from both Nick and Monroe like they were hit with flower petals. However, their weakness is [[spoiler:cutting their hair, which strips them of their strength and will to fight]].
* JumpingOffTheSlipperySlope: In "Hour of Death", [[spoiler: Ryan the Grimm-wannabe intern]] initially tortured and killed the two [[AssholeVictim Asshole Victims]] since they had kidnapped a young woman, but then goes after Bud the Eisbiber, an innocent bystander not even involved in the case.
* JuryAndWitnessTampering: In the episode "One Angry Fuchsbau," AmoralAttorney Barry Kellogg is influencing both the witnesses and the jury via MindControl.
* JuxtaposedHalvesShot: Juxtaposed halves was a common motif used in the opening montage of ''Series/{{Grimm}}'', first we see a half-and-half shot of Monroe; the right hand side is his human form and the lefthand side he's in his wessen (monster) form. A few seconds later we see it again but with another character, Rosalee.
* KavorkaMan: How ''ziegevolk'' appear to the world: unattractive (or at least, not handsome) men with a knack for landing incredibly attractive women.
* KickTheDog: Renard's brother Eric sells out an apparently loyal retainer of seven years' service solely so he can see [[spoiler:the Cracher-Mortel]] in action. He takes particular delight in the knowledge that the man is suffering terribly.
* KissingUnderTheInfluence: [[spoiler:When Rosalee is infected with the Yellow Plague, she kisses Monroe, as increased libido is one of the symptoms. Thankfully Monroe realizes very quickly something is wrong with her.]]
** In the episode ''Face Off'' [[spoiler:Juliette and Renard are at each other like no there's no tomorrow, a result of the after-effects of Renard awakening Juliette from her coma. Due to what this does to their self-control and sanity, their encounter alternates between [[KissKissSlap the two of them half a minute away from full-blown sex, trying to stop and turning violent]]. ]]
* KnightTemplar: While we don't know how Grimms operate in the modern world, previous generations are possibly implied to have fallen under this category, judging from [[OhCrap the reaction]] of many creatures when they realize what Nick is. Monroe's description of what [[VanHelsingHateCrimes they did]] to his grandfather certainly paints a vivid description of their form of justice. Although we know that grandpa deserved it. As we know that nearly all blutbaden are killers, or at least dangerous. Even Monroe admits to having killed before he became reformed, its very hard to say if it was or wasn't justified. So far all the creatures recorded in the Grimm books that Grimms killed deserved it. So mileage may vary on this.
** Averted, and takes a sharp right turn into VanHelsingHateCrimes as of The Other Side, wherein a Grimm on Charles Darwin's voyage to the Galapagos Islands documented a peaceful, gentle, thoroughly nonviolent species of wesen who had no cultural history of contact with the Grimms and hence, no fear of them, "which made the dispatching of them quite easy."
* LadyInRed: Blutbaden are provoked by the color red. Which is worrying, since Nick's girlfriend Juliette often wears red.
** And [[HeroesWantRedheads is a redhead]].
* TheLancer: Hank Griffin in law-enforcement matters and Monroe regarding Grimms and the supernatural.
* LaResistance: There is a resistance movement among Wesen that opposes a powerful wesen conspiracy that has been infiltrating human governments and advocates racial purity.
* LamePunReaction:
** From "Beeware":
--->'''Hank:''' The beekeeper just buzzed me. [[LampshadeHanging That's right. I went there.]]
** From [[Literature/ThePiedPiperOfHamelin "Danse Macabre"]]:
--->'''Sergeant Wu:''' Looks like they're gonna have to face the music.\\
'''Hank:''' ... [[LampshadeHanging Really? You went there?]]\\
'''Sergeant Wu:''' [[ForTheFunnyz Somebody]] [[ObligatoryJoke had to.]]
* LampshadeHanging:
--> '''Nick:''' He's a Wesen.\\
'''Renard:''' Isn't everyone these days?
* LaserGuidedAmnesia: Due to Adalind's curse, [[spoiler:Juliette]] for much of season 2 could remember everything else about her life except for [[spoiler:Nick]].
* LaserGuidedKarma:
** In "Beeware", [[spoiler:Nick guns down a Mellifer queen. At the end of the episode, he's stung by a bee. What makes this look a lot like direct payback is the fact that the bee first lands gently on the back of his right hand, ambles around harmlessly for a moment, and then ''stings his trigger finger'']].
** In "Best Served Cold" Monroe gets the positive version: [[spoiler:His non-violent vegetarian lifestyle lets him avoid being poisoned.]]
** In "The Good Soldier" [[spoiler:the wife of a rapist soldier. He wrote a confession and showed it to her, explaining he kept secret because of peer pressure and his fellow rapists calling him a coward and weak. After a moment, she agrees ''with the other rapists'' and demands he burn the confession. Not a minute later, she is killed by the lead rapist]].
** In "Synchronicity" and "Law of Sacrifice" Adalind's past misdeeds finally catch up with her. Every bad thing that happens to her in these episodes is an ultimate consequence of choices and actions we've seen her undertake in the course of the series. [[spoiler:It culminates with her baby being taken away from her.]] And it happens even with everyone she's screwed over trying to help her instead of taking revenge.
* TheLastDance: Invoked in "The Good Soldier" with [[spoiler:Col. Desai, dying of cancer, against a rapist private military contractor. As both are manticores, the other has no qualms with it, considering it to be part of their nature]].
* LastStand: [[spoiler:Sebastien covers Meisner and Adalind's escape and gets one against Viktor and his men. He takes out all the foot-soldiers but runs out of bullets before he can shoot Viktor.]]
* LatinoIsBrown: Averted. Fair-skinned, redhead Juliette is Spanish, bonus as she is fluent in the language as well. Also counts as an ActorAllusion since Bitsie comes from mixed Scottish/Spanish descent.
* LonersAreFreaks: The ostracized teenager in "Danse Macabre" was treated like this. In the same episode, Nick empathizes with the teen and implies that he was once a loner, too.
* LongerThanLifeSentence: In "Game Ogre", Stark was serving a 300 year prison sentence when he escaped and came looking for revenge.
* LovableCoward: Bud Wurstner, since Eisbiber are friendly and non-confrontational by nature. That said, he is willing to help his friends when the need arises.
* LoveIsInTheAir: Ziegevolks have the power to charm anyone with their touch.
* LoveTriangle: Enforced by [[spoiler: Adalind]] on Nick, Juliette, and [[spoiler:Renard]] by [[spoiler: wiping all Juliette's memories of Nick and]] enchanting the latter two into obsessive feelings for each other.
* {{Masquerade}}: Initially, it seems like there is a fight between the Grimms (and their allies) against the creatures who aren't as concerned with humans. By the second season, it's clear that the conflict is very convoluted and not nearly as straight forward.
** Unlike many universes, there's actually a formal Masquerade in play that was written and codified by a meeting of all wesens across the world sometime around the 13th century with jurisdiction over it given to a Wesen Council. Breaking of it is grounds for death as previous {{Broken Masquerade}}s resulted in things like the Witch Trials.
** The penalty of death is also distinct among Masquerades since the punishment is not dealt to witnesses but to those that broke the masquerade. All of which makes it much more like a code of honor (it's practically called as such by Monroe) and less a pragmatic reality or arbitrary ruling compared to other such universes.
* MadeOfIron: Ogres are ridiculously hard to kill, but they're not immortal. The simple way to kill them is with an extremely rare poison that calcifies their bones and makes them brittle enough to shatter from the inside out; or, simple overwhelming force can be applied. Both of these approaches get combined when [[spoiler:Monroe poisons the rounds he fires through Marie's antique triple-barrel elephant rifle, taking Stark down in one shot]]. Presumably, anything invoking the ChunkySalsa Rule would also work.
** Grimms are also this to a degree. That Nick was capable of taking a beating from a Skalenzahne in "Last Grimm Standing" and ''still'' manage to easily best it, heavily implies that Grimms have far superior strength and stamina than most ''Wesen''. The aforementioned Ogre however, is something clearly beyond even their limits.
* MagicKiss: The kiss of the musai instills an obsessive attraction that fuels artistic passion then leads ultimately to obsession and death.
* MagicalSecurityCam: [[ImpliedTrope Implied]] in 'Beeware' when Nick asks if they can "do anything" (answer: "no, the camera's stationary") with recorded footage of a [[FlashMobCoverup flash mob murder]].
* ManHug: Bud the Eisbeber hugs both Nick AND Hank after [[spoiler: they had saved him from the Grimm wannabe]] in "The Hour of Death".
* MaybeMagicMaybeMundane: It is never said for sure if the coins in "Three Coins in a Fuchsbau" are really magical or the people holding them are suffering from delusions caused by arsenic and mercury poisoning. The irony of the situation is that this is a universe with dragons who can breathe fire, ogres who are almost impervious to normal weapons, and satyrs that can charm you with their touch. Given instances of Wesen activities (human organs as herbal remedies) and Adalind's special cookies, it may be quasi-magical by our perception but mundane chemistry with a Wesen touch in the Grimm universe.
** Although, if you look carefully, Hank, who was affected by the coins, never came into skin contact with them...
** Not to mention the fact that the coins bring out the ''exact'' same [[PuttingOnTheReich symptoms]] in the people who possess them...
** And then of course, there's the Halloween special in which we see what may or may not be a ghost. All we're told is that it's mostly likely not a wesen or if it is, not like any other wesen ''any'' Grimm from Nick's family has ever seen.
** In ''Volcanalis'', the titular creature is most definitely not a Wesen, but the jury's still out on what exactly he is.
* MeaningfulName:
** Gilda Darner is the name of the victim of the week in a Goldilocks-themed story. Gilda as gilded or gold. She also is a blonde.
** More groan-worthy is the young Jägerbar named Barry. Whose last name is Rabe, an anagram of "bear".
** One of Barry's friends Jägerbar friends is named 'T.B.', as in 'Teddy Bear'.
** In "Beeware" the Queen Bee of the Mellifers is Melissa, which means "honey bee" in Greek.
** In "Lonelyhearts" the antagonist of the episode is a creature based off satyrs. The antagonist is named Billy Capra. As in billy goat, which satyrs have the legs of. And Capra which is the genus of goats.
** Lieutenant Orson in "Three Bad Wolves" shares a name with a pig character from [[USAcres U.S. Acres]].
** Oleg Stark[[note]]"Stark" means "a stern, determined or physically strong man", literally German for "strong"[[/note]] in "Game Ogre."
** "Organ Grinder", an episode loosely based off of "Literature/HanselAndGretel", had two central characters named Hanson and Gracie.
** Leo Taymor the Lowen in "Last Grimm Standing". Nick actually [[LampshadeHanging Lampshades]] this one.
** A bird based wesen named Robin.
** The antagonist of "Nameless". Of course, given the story the episode draws from, it's a given. [[spoiler: Not Rumpelstiltskin but an anagram of it.]]
** "Renard" is the French word for fox, and the Captain is certainly a clever and tricky one.
** Adalind Schade pronounces her last name as "Shade", but as "shah-duh" which sounds similar to the German word "Schaden" for "damage/harm". "Schade" however means "It's a pity".
*** The Austrians and the Gypsies prefer the German pronunciation, even scolding Adalind for using the Americanized pronunciation.
* MegatonPunch: Hank delivers one in "Bad Moon Rising" to [[spoiler: the Coyotl who lunged at him and his goddaughter.]]
** Hank's pretty good at these, actually. He took down a [[spoiler: male naiad in "One Night Stand" and a crazed zombie in the web series "Meltdown".]]
* MemeticBadass: Grimms to Wesen, InUniverse. While it is important to note that not only do Grimm's have the ability to see Wesen in their true form. But also have heightened speed, agility and strength as well to gain other abilities if circumstance allow such as Nick's enhanced hearing. It's is also the centuries of hunting and thus the downright mythical stories told of Grimms by Wesen to each other and their children that give Grimms their fierce reputation and legendary status.
* MenAreTheExpendableGender: Overwhelmingly, victims tend to be male. Even the initial multi-victim attack in "Bigfoot" ends up with the sole female still alive.
* MentorOccupationalHazard: Aunt Marie ends up in a hospital bed after an attack by Hulda the Troll, and a nurse reveals Marie's body is CoveredWithScars. Nick fends off another attempt to kill her while visiting her. [[spoiler:She dies in the second episode]].
** The wesen mentor in "Happily Ever Aftermath" ends up like this too [[spoiler:at the hands of his mentee, no less.]]
* MermaidProblem: Averted by the female naiads, who not only have sex with human men in their non-woged form but keep their legs in woged form as well.
* MindOverMatter: [[spoiler:Adalind's baby]] is rapidly showing to be proficient in this, even forcing a Verrat to commit a PsychicAssistedSuicide. Presumably, all [[WitchSpecies Hexenbiests]] and Zauberbiests have this to a limited extent, but [[spoiler:the baby]] turns this UpToEleven having been supercharged by [[spoiler:the ritual that returned Adalind's powers]].
* MindScrew: In-universe this happens to Hank. Warning to the wary, never eat cookies from a hexenbiest.
* MistakenForCheating:
** After Nick was tackled by Ariel in "Plumed Serpent" when at her house, she takes his ringing phone and answers with Juliette on the other end, to make it seem like Nick was cheating on her. Fortunately, once Nick explained what had really happened, Juliette believes him.
** And in "El Cucuy", the email from [[spoiler:Nick's Mother]] Juliette read had her furious. [[spoiler: Thankfully, the misunderstanding doesn't last long.]]
--> '''Juliette''': Want to tell me who M is and why she loves you? I'm assuming it's a she.
* MomentKiller:
** In "Endangered" Nick, needing Monroe's help, walks into his place, up to the fridge and grabs a beers, sipping from it before realizing Monroe and Rosalee were in the middle of a date. He quietly excuses himself from the room.
** Monroe returns the favor with a well-timed phone call in "Kiss of the Muse." Considering that he phoned just as the musai's seduction of Nick was starting to work and brought up Nick's dinner plans with Juliette, this is a good thing.
* MonstersAnonymous: Monroe is a member of a group of Wesen trying to suppress their more violent natures.
* MonsterOfTheWeek: Looks like that's going to be the format here. That said, the show does seem to make an effort to have recurring creatures outside of the MythArc creatures like blutbaden. As the series has progressed and matured to the point where much of the initial world building has already taken place, it has become less about new monsters and more about the drama. To a certain extent, the PoliceProcedural aspects have been toned down as well, serving more as an excuse for Nick to get involved/informed about the situation than as an actual story line where someone gets arrested.
** As the show progresses, more episodes devote time to the underlying Royals arc, even the Monster of the Week ones.
* MoralityPet: From the perspective of wesen, Monroe and Rosalee are this. Had Nick not encountered a few of the good ones first, he could very well have ended up more like his ancestors. [[spoiler: For Nick's mom, on the other hand, Monroe and Rosalee are more like [[MoralityChain Morality Chains]] in regards to whether or not she'll kill them and otherwise actively hunt in Nick's turf.]]
* MuggingTheMonster:
** Human criminals going after certain Wesen are going to be in a world of hurt. Even the peaceful Monroe is capable of ripping a man's arm off without much effort. In "Bears Will Be Bears", this happens to three different groups of human criminals. Even those species that aren't gifted with physical capabilities or supernatural abilities tend to have quirks that make them hard to deal with. The mouse creature in "Of Mouse and Man" is shown crawling through small spaces far faster and better than a human could.
** Played with when Wesen attempt to fight Nick, as ''he'' is the monster that ''they'' fear. Given that he's been revealed to be stronger than Monroe (who can rip a man's arm off), this starts to make sense.
** A milder, more comedic example shows up in ''La Llorona'', when some young bullies smash [[RetiredMonster harmless]], [[WolfMan eccentric]] [[BewareTheNiceOnes Mr. Monroe]]'s window because he stopped them from picking on a smaller girl. Borders on BullyingADragon because he's much bigger than all of them and had already twisted one's ear to make them give her back her Halloween candy.
** Quite literally, at the end of "El Cucuy". It was a bad idea for that punk to [[spoiler:grab that sweet old lady's purse, seeing as how she's the "boogeyman" that punishes the wicked]]...
* {{Muggles}}: An ordinary human--that is, anyone who isn't a Wesen or a Grimm--is called a "Kehrseite" by Wesen. Kehrseite who know about Wesen are called "Kehrseite-Schlich-Kennen," but [[{{Masquerade}} the secret]] is strictly guarded against wider exposure. Nick has to deal with not only solving Wesen-related crimes but explaining away the weirdness to those not in the know, particularly his normal human partner, Hank, [[spoiler: until Hank becomes a Kehrseite-Schlich-Kennen.]]
* MurderTheHypotenuse: Goes right along with Ariel's StalkerWithACrush antics.
** Since naiad males are sterile, they have to raise the offspring their women conceive with human men. This led to an old tradition, now mostly abandoned, of killing off their women's human partners after the act.
* MyGreatestFailure: In "The Good Soldier" [[spoiler:Col. Desai feels this way about his inability to get military justice for a woman raped under his command by three soldiers and a private military contractor in Iraq]].
* MySpeciesDothProtestTooMuch: The actual term for a wesen who subscribes to this is "weider," or "against." The degree of difficulty wesen have at maintaining this state varies from species to species, and from individual to individual. Most of the wesen in Portland are "weider" to one extent or another, since most of them are law-abiding citizens, but ([[MonsterOfTheWeek due to the nature of the show]]), lots of ''non''-law-abiding wesen show up too, many of them from out of town and subscribing to "the old ways."
* NakedInMink: In "Bears Will be Bears", Gilda seduces her boyfriend by suggestively opening a fur coat she's wearing to reveal her lingerie-clad body.
* {{Names to Run Away From Really Fast}} : If you know German (and can get past the BlindIdiotTranslation pain/giggles), then names like Blutbad and Daemonfeuer are this in spades. (Means “Blood Bath” and “Demon Fire” respectively). Some of the other Wesen names are none too cuddly sounding as well.
* NaziGold: The eponymous coins from "Three Coins in a Fuchsbau" were assumed by Hank to be this because of the swastikas on them. Turns out [[spoiler: they were much older (dating back to AncientGreece, though they ''did'' fall into Nazi hands for a while and may have been [[{{Ghostapo}} partially responsible]] for [[BeethovenWasAnAlienSpy Hitler's]] delusions of grandeur and aggressive charisma.]]
* NeverHeardThatOneBefore: Monroe warns Nick not to make "heel" commands to him while he helps scenting out the MonsterOfTheWeek. Nick replies with "good boy" instead, to Monroe's dismay.
* [[NeverMessWithGranny Never Mess with Auntie]]: Aunt Marie really puts the English on the trope given she's ''dying of a terminal illness'' and still takes on Hulda with only a knife (a knife concealed in the handle of [[SwordCane her cane]], that is) and her BaldOfAwesome. We find out later she was a BadassBookworm, having been a librarian by trade. She also stares down Monroe while she's clinging to life in a hospital bed. Considering we see Monroe rip off a man's arm a few scenes later, that took no small amount of guts.
* NeverSmileAtACrocodile: Two types of wesen - the crocodilian skalenzahne, and the alligator-like gelumcaedus.
* NeverTrustATrailer: One of the Season 2 episodes advertised Juliet getting her lost memory back, and the return of ex-Hexenbeast Adalind Schade. What actually happens? [[spoiler: Juliet's recovery was AllJustADream, and Adalind only appeared in the context of phoning police chief Renard to ask about who killed her mother. She didn't actually return to Portland for another five episodes.]]
* NewsTravelsFast: Even a Grimm involved in a stealth hunt has heard of those two Reaper heads mailed back to France.
* NoodleIncident: In “Bad Teeth” Monroe makes an offhand mention about how (badly) family reunions can go, mentioning that one of his ending in the death of two cousins and a sheepdog. Apparently nobody missed the cousins....
* TheNoseKnows: Various Wesen have a supernatural sense of smell, particularly Blutbad like Monroe.
* NonHumanSidekick: Monroe.
* NonIdleRich: Though not exactly rich, Monroe is affluent enough to indulge in fairly niche hobbies and has enough spare time to help Nick out on a regular basis. Given his occupation though, it's perhaps justified as people of his skill and talent are few and far between so he can charge a premium.
** Though it seems he fixes clocks more as a paid hobby/passion/something to keep himself occupied, rather than an actual livelihood to support himself.
** Captain Renard seems to be doing rather well for himself, though he ''does'' [[spoiler: [[RoyalsWhoActuallyDoSomething hail from a royal line]].]]
* NotSoDifferent: Orson confronting Nick when the latter knows that he's of Bauerschwein origin. The former believes that they should work together as police officers and not in the Grimm - Monster hunting view. Nick doesn't agree, [[spoiler:considering Orson's involvement in Hap's death]].
* NoSell: For wesen, the voge (GameFace) is one of their go-to trump cards against normal humans, who usually GoMadFromTheRevelation of their monstrous faces. Practically every wesen has tried this on Nick, who as a Grimm is immune to the effect. [[SmugSnake The formerly smug]] wesen [[OhCrap don't react well]].
** Hank initially started going crazy, but repeated exposure (thanks to Monroe) has allowed him to build his immunity to the effect.
** [[spoiler: Juliette]] is also working up a tolerance. When [[spoiler: her friend's abusive husband]] woges in an attempt to intimidate her, she doesn't even blink and proceeds to keep on fighting him and ''win''.
--> [[spoiler: '''Juliette:''']] I'm not impressed.
* NoSwastikas: Averted. Renard goes into detail about the history of the Swastika, and what it originally meant.
[[/folder]]

[[folder:Tropes O-S]]
* ObligatoryJoke: In "Danse Macabre" while examining the body of a high school orchestra conductor:
-->'''Sgt. Wu''': Looks like they'll have to face the music.
-->'''Hank''': ...You really went there?
-->'''Sgt. Wu''': ''Somebody'' had to.
** Again in "Leave It To Beavers" after [[spoiler: the two reapers [[OffWithHisHead are beheaded]],]] Nick says "they got angry, kinda [[OffWithHisHead lost their heads.]]
* OddFriendship: Some of Nick's closest friends are Wesen. To say this is unusual amongst Grimms is an understatement.
** Inverted/averted in the case of [[spoiler: Hank and his coyotl best friend. Granted Hank didn't know at first that his friend was a wesen but ''his'' friend didn't seem to think it particularly odd to be friends with a human.]]
* OffWithHisHead: Reapers traditionally kill Grimms by decapitating them with their large scythes. [[spoiler:Nick is able to best two of them and does the same - then sends their heads to their commander as a message.]]
** Also traditionally, Grimms prefer this method of dispatching Wesen. Prior to the Brothers Grimm popularizing the name, Grimms were known as "Decapitare", meaning "decapitator" in Latin. Some isolated Wesen still use the term.
* OhCrap: The reaction of various creatures upon learning that Nick is a Grimm has basically been "oh god oh god please don't kill me." Nick has used this to get information, but other times he's clearly getting exasperated at having to explain that he's not the indiscriminately beheading type.
** In "Leave it to Beavers", the look the Reaper in Germany has when [[spoiler:he discovers his parcel contains the severed heads of the two Reapers tasked with eliminating Nick. As well as a note from him.]]
-->'''[[spoiler:Nick]]:''' [[spoiler:Next time, send your best.]]
** It also seems to be the immediate reaction of more timid Wesen to the more naturally predatory kind, as shown when Monroe causes a minor panic in a church full of Seelengut just by walking in and sitting down. Though slightly justified on their part since Monroe was in partial GameFace so they knew/felt right away that a strange blutbad just arrived. And given the typical reputation of blutbaden combined with seelengut being literal sheep, they could not know what might happen.
** Monroe and Juliette get a mutual one at the end of "To Protect and Serve Man" when [[spoiler:Monroe catches Juliette and Renard kissing in the throes of their potion-induced obsessive passion.]]
** A particularly hilarious and well-deserved one appears in "Endangered"
-->'''Victim:''' (woges)\\
'''Villain:''' You're worth a lot.\\
'''Monroe:''' How much is a Blutbad worth? (woges)\\
'''Villain:''' (smiles) A good amount.\\
'''Rosalee:''' What about a Fuchsbau? (woges)\\
'''Villain:''' (grinning) A whole lot more than a Blutbad.\\
'''Nick:''' What about a Grimm? (doesn't woge)\\
'''Villain:''' {{Oh Crap}}...\\
'''(Cue tag team attack by Monroe and Nick)'''
** Monroe and Rosalee share one when Juliette reveals that she remembers Nick telling her about Wesen and she now believes him.
** Juliette's fuchsbau friend Alicia has one when Juliette too-casually throws out that Nick is a Grimm. Followed shortly thereafter by Alicia's [[DomesticAbuser abusive klaustreich husband]] crashing into the house and (after getting his ass kicked by Juliette and Alicia) belatedly realizing the same thing. He agrees to leave Alicia alone after this.
** ''The Wild Hunt,'': [[spoiler: Monroe's parents encounter Nick and discover he's a Grimm]] They prepare to fight each other and...the screen fades to black, [[PaintingTheMedium with]] the words [[OhCrap Oh $(*@&]], followed by ToBeContinued.
** In "Synchronicity" Adalind has a profound and gratifying one when she realizes that her protector has [[spoiler:brought her to Nick and Juliette's house and is Nick's mom]].
** ''Many'' toward the end of "Blond Ambition". Particularly Renard, once he realizes what Adalind has been up to, Trubel when she bursts into a wedding chapel full of Wesen, and most importantly, [[spoiler:everyone present when they find out that Nick has been BroughtDownToNormal]].
* OmniscientCouncilOfVagueness: The Wesen Council, which oversees and enforces Wesen laws. They seem to be a sort of GodzillaThreshold, because lots of Wesen-committed crimes pass completely under their radar.
* OnceAnEpisode: Each episode begins with a quote from a story, fairytale, or poem relevant to the episode in question. Nick also ends up calling on Monroe for ''something'' in every episode (whether Monroe likes it or not), even before Monroe officially decides to partner up.
* OneDialogueTwoConversations: Nick and Adalind in Season 1's ''Beeware'', since he knows she's a Hexenbiest, and she knows he's a Grimm. When he has to question her for his case, they discuss it but take subtextual shots at each other with their word choice.
* OneDrinkWillKillTheBaby: When a pregnant [[spoiler: Adalind]] tries to take a drink to seal a deal [[spoiler: to sell her unborn child]], another party immediately snatches the bottle from her and demands, [[HypocriticalHumor "What kind of mother are you?"]]
* OneGenderRace: The satyr-like Ziegevolk, who impregnate human women. [[spoiler: Although as of the web series, "Love Is In The Air," this may be subverted.]] The Spinnetods are not a one gender race, but only the females have the degenerative condition that makes them prey on young men, and the males are, as a rule, killed by their mates (the husband Spinnetod in "Tarantella" being an exception).
** Hexenbiests seemed to follow this, until a male example in [[spoiler:Captain Renard]] was revealed. Rosalee later clarifies in "Mr. Sandman" that Hexenbiests are exclusively female, and males are known as Zauberbiests (literally "wizard beast," to compare with "witch beast.")
* OneHourWorkWeek: Monroe, who doesn't have a regular job, and only works when he is hired by someone. He has enough time to hang out at the spice shop and help Rosalee, who also doesn't have a lot of customers come in unless it's relevant to the plot.
* OnlyThePureOfHeart:
** To awaken from her coma, Juliette needs to be kissed by someone "pure of heart". But since such people are very rare these days, there is a nasty potion that purifies the drinker's heart, quite painfully if he's not that pure to begin with. [[spoiler: With the aid of the potion, Renard fulfills the requirements and wakes her]].
** Because of the above, [[spoiler:Juliette and Renard slowly become obsessed with each other and come close to killing each other. Part of the process to cure them requires Nick to drink the same purification potion Renard did.]]
* OpeningNarration: In this case, it seems, as of the first episode, to be a quote from the fairy tale the villain of the week comes from.
** Season 2 adds an opening narration for the opening credits along with an actual open credits sequence. Though apparently YMMV on the shows part since while the visuals have remained mostly the same, the narration itself has changed, been absent, and had multiple voice over actors.
* OpiumDen: Nick and Monroe track a couple of Wesen junkies into one specifically for Wesen (if a human were to smoke the stuff, they’d die). The smoke messes with Monroe’s nose.
* TheOtherRainforest: Set and filmed in Portland, Oregon. There are a lot of little in jokes that are funnier if you're a Portlander or an Oregonian (two eisbibers being really big OSU fans, for instance)
* OurDragonsAreDifferent: Daemonfeuer, Wesen descendent from a dragon-like lineage. They can breath fire by vaporizing their body fat and igniting it, seem to hoard copper, and are [[spoiler:fireproof]]. As with the werewolf entry below, Monroe makes the important distinction that dragons are a myth while the wesen that inspired them are real.
* OurMonstersAreDifferent: Called 'Wesen' in-universe. TheOtherWiki has a more complete list.
** For many wesen, their abilities are natural and can be detected through mundane means, particularly purely physical attributes like strength (blutbaden), hair growth (wildermann), or toughness (ogres). Others like the wesen from "Mr. Sandman" don't have any special powers per se, but do share a symbiotic relationship with something fairly mundane (a parasite in that specific case). Still others like the mellifers and the jägerbärs are shown to use use tools similar to their animal counterparts. Suffice to say, there's a lot of variation among wesen as to the extent of supernatural abilities.
** The Blutbaden are the basis of TheBigBadWolf.
** The Bauerschwein are the basis of the Literature/ThreeLittlePigs. Needless to say, Blutbaden and Bauerschwein typically aren't on friendly terms.
** The Jägerbärs are the basis of the {{bears|AreBadNews}} of Goldilocks and the Three Bears.
** The Mellifers are the basis for ''The Queen Bee''.
** The Reinigen are the basis for The Pied Piper.
** Hexenbiests are the basis for several evil witches, including the Evil Queen from ''Snow White'' and the witch from ''Donkey Cabbages''.
** The Nuckelavee are based off the nuckelavee of Orcadian lore. For those unfamiliar, they're a horse-like creature.
** La Llorona from the episode of the same name comes from Mexican folklore.
** The Fuchsteufelwild is based off of goblins, as well as ''Literature/{{Rumpelstiltskin}}'', whose name all of their own names are {{Significant Anagram}}s of.
** The Musai is an elfin creature based off the legend of the leanan sidhe, a type of fairy muse who inspires artistic passion but ultimately leads her victims to madness and death.
** El Cucuy is a Spanish/Portugese variation of the boogeyman, said to take and devour disobedient children. The ''Grimm'' version is attracted by the outcry of victimized women and kills violent criminals.
** Koschei (spelled "Koschie" in the show, for some reason) is an undead villain in the RussianMythologyAndTales (his full name is Koschei the Deathless). While in the folklore he's impossible kill unless the hero finds his carefully-hidden death, the show's Koschie is a radioactive partly-skeletal monster who can take away and give sickness and has a HealingFactor, making him difficult to kill (Rasputin was a Koschie).
* OutrunTheFireball: Nick does this in “Plumed Serpent”
* [[OutsideContextVillain Outside Context Ghost]]: [[GhostStory La Llorona]]. Not even Grimms, the expert hunters of Wesen, know what she is exactly. One that went after her never came back. She is the first "undead" creature to appear in Grimm.
** Soon followed by an [[OutsideContextVillain Outside Context Demon]] with [[OurDemonsAreDifferent Volcanalis]]. A fiery creature that can fry you from the inside out if you anger it by stealing the rocks in its domain. One of these things [[PersonOfMassDestruction caused Mount Vesuvius to blow up and bury Pompeii in ash.]]
* OutWithABang: [[spoiler:Adalind’s potion was intended to cause this in Hank]].
* PaintingTheMedium: Literally. The Writers of Grimm apparently got bored with "To be Continued" and since the season 2 mid-season finale have been using messages such as "To be continued... sorry", "It ain't over yet" and "[[SymbolSwearing Oh #@&%!]]".
* PapaWolf: Bart, Monroe's father, is this. [[spoiler:When he followed his son to Nick's trailer and they were attacked by Cacia Morte, insanely powerful and believed to be unbeatable Wesen, he jumped right in, fighting next to Nick and Monroe against these ancient foes]].
* PhraseCatcher: The first two things usually said to Nick after a wesen figures out what he are [[CaptainObvious "You're a Grimm."]] and ''[[OhCrap "Oh God PLEASE DON'T KILL ME"]]''.
* ThePlague: The Yellow Plague is very deadly to Wesen that comes from pigs. Entire villages have been wiped out from it and the bodies are burned. Thankfully, though, it requires physical contact that breaks through the skin to pass onto the other victims.
* PlayingWithFire: The Wesen in “Plumed Serpent”, known as Daemonfeuer, have [[BreathWeapon fire breath]]. They apparently do this by vaporizing their fat, “vomiting” that vapor into the air, then somehow igniting it through static electricity. The family includes [[MundaneUtility two flamethrower operators, a welder, and a fire dancer]], so they obviously quite like fire.
* PoliticallyIncorrectVillain: The Naiad villains in "One Night Stand" were [[{{Misogyny}} misogynistic]].
* ThePowerOfBlood: There are several kinds of potion that include blood of the maker and blood of the target as ingredients; these potions can only be cured by killing the person who made it. Futhermore, [[spoiler:if a Hexenbiest ingests the blood of a Grimm they [[BroughtDownToNormal become human]].]]
* PoisonedWeapons: The [[spoiler:bullets]] in Game Ogre were poisoned.
* ProductPlacement:
** iPod, iPhone, and Nike, all within the first five minutes of the first episode.
** "Beeware" has the sounds particular to Android phones.
** There’s also product placement for obscure products you’ll only find in Oregon. In one episode you see a box of Voodoo Doughnuts, a shop that’s only in Portland, Eugene, and Seattle (and rather famous locally) and in "Lonelyhearts" the beer Monroe orders, Double Dead Guy, is brewed in Bandon, OR.
* ProfessorGuineaPig: the psychiatrist in "Big Feet"
* PunBasedTitle: "Game Ogre" (Game over), the episode about a Siegebarste named Oleg Stark.
* [[CatScare Raccoon Scare]]: Early in “Of Mouse and Man”, Juliette and Nick get out of the house to investigate strange noises. It’s a raccoon looking for its dinner in their trash can.
--> '''Nick:''' I am not eating what he’s eating.
--> '''Juliette:''' Sure you are, you just got to it first.
* RecordNeedleScratch: A modern version but in "Leave It To Beaver", Juliette cozies up to Nick and the background music begins to play romantic music. When she reveals she actually just wants to invite Monroe over for dinner, the music stops abruptly.
* RewindReplayRepeat: "Beeware" has Nick repeatedly rewatching the FlashMob videos taken by various security cams in hopes of finding the person killing people at each FlashMob event.
* RapeAsDrama: The entire episode of "Lonelyhearts" was about a satyresque monster called a Ziegevolk, making him a serial rapist by human standards.
* RasputinianDeath: Rasputin himself suffered this. [[spoiler:He was a Koschie, a type of wesen that have incredible healing abilities and are incredibly hard to take down. He was killed by a British Intelligence Officer who happened to be a Grimm]].
* RealLifeWritesThePlot: Russell Hornsby, the actor who plays Hank, sustained a serious foot injury during Season 2. Naturally, there's no way to work around this on a cop show, so instead they sent Hank on vacation for an episode and had him return with a similar injury.
* RecruitedFromTheGutter: A [[MonsterOfTheWeek Bad Guy of the Week]] recruits homeless young women, dresses them in fine clothes, then sends them out to shoplift from high-end fashion boutiques.
* RecurringExtra: Bud Wurstner, the Eisbiber plumber. He starts out being terrified of Nick, but they soon form an odd friendship and Bud eventually helps out on occasion.
* RedEyesTakeWarning: When Blutbaden get pissed, their eyes turn red.
* RedemptionEqualsDeath: In "Red Menace" [[spoiler:the alleged reformed FSB wesen assassin-turned-healer heals his murderer, a maid of the house, when his wife took a chunk out of her neck for trying to kill her husband. The former FSB had previously killed the maid's father when she was 10 and her brother this episode]].
* RetiredMonster: Implied to be the majority of the creatures, at least among the more predatorial species. In the second episode, when one of the Jägerbärs is told that his family is performing the traditional manhood ritual (which involves hunting down and killing someone), the first words out of his mouth are, "What? No one does that anymore." It also explains why Blutbaden, whose hungry urges are triggered by the color red, haven't eaten everyone. For other Wesen like Spinnetods, they're rare because the particular demands of their biology aren't compatible with a normal life.
** The term 'wieder' Wesen has come up as a way of describing those wesen who are capable of controlling/mastering their Wesen aspects such as Charlotte and Monroe.
* {{Retcon}}: Initially, Marie told Nick that Grimms inherit their powers when the Grimm of the previous generation dies and passes them on. In season 2, [[spoiler:Nick's mother]] tells him that the powers awaken at a random age to those in the family line, with girls getting the powers younger than boys. This explains away certain headscratchers and justifies why Nick received the sight so late in life.
** In the first episode Monroe states he avoids other Blutbaden because bad things happen when they get into packs. Later in said episode he shown to be physically affected by the other's presence, starting to lose control over himself, forcing him to leave or else he might attack someone. However, in a Dish Served Cold, almost every Bludbad in Portland in shown in the same spot with no ill effects on any of them.
** In early episodes wesen weren't automatically aware that Nick was a Grimm when he saw them woge, they had to intuit it based on his reaction to them. As the show progressed it became an instinctive recognition. In "Synchronicity" it's described as something the wesen see in the Grimm's eyes.
* TheReveal: Captain Renard, Nick and Hank's superior, knows about the existence of Vesen and is somehow tied to them.
* RevengeByProxy: In "Three Bad Wolves", one Bauerschwein (a pig wesen) decides to get even with a Blutbad (a wolf wesen), who had murdered his brothers for fun. So he targets said Blutbad's brothers.
* TheRevolutionWillNotBeCivilized: A major theme of the series is that the relationship between oppressor and oppressed is fluid, and that those on the bottom will often be just as selfish and exploitative as those currently on top if they are given power.
-->'''Edward Waltz''':''You may think I'm a monster but what I am is necessary. No society can survive without order. Free thought is not free - there is no such thing as revolutio - the oppressed always become the oppressors and the cycle repeats itself over and over. The only way to win is to stay out of the cycle.''
* RunningGag: Monroe's introduction in each episode seems to always revolve around him doing a very normal, very mundane activity and trying very very hard to ignore Nick and the inevitable creature-related problem. In "Organ Grinder", he brings this fact up and tries to have a normal conversation--it rapidly and awkward devolves into Monroe's favorite color (red), how human organs are like homeopathic remedies for Wesen, and Nick and Monroe talking about human testicles as the Wesen equivalent of Viagra.
-->'''Monroe''': Maybe I should just get you your own key.
** Becomes HilariousInHindsight by episode 12 of season two because [[spoiler: Nick decides to stay at Monroe's place due to the complicated situation with Juliette and Renard.]]
* RoaringRampageOfRescue: Nick goes on one of these in “Plumed Serpent."
* RoaringRampageOfRevenge: [[spoiler:Adalind's]] currently on one. "Hell hath no fury like a woman scorned" indeed. The fact that [[spoiler:she's also trying to avenge her mother's death]] is the icing on this particular cake.
* SacrificialLion: [[spoiler:Angelina]], killed making a HeroicSacrifice to save [[spoiler:Monroe's]] life.
* SarcasticConfession: The FBI, who found a hair with partial DNA match to Nick's at a warehouse where two FBI agents and their killer died, ask him who he's protecting.
--> '''Nick:''' [[spoiler:"My mother."]]
* SamusIsAGirl: [[spoiler: El Cucuy]] is actually [[spoiler: a 77-yo old grandmother, despite the masculine El.]] Though in the original folktales, there is actually both a female and male version of the creature.
* SantaClaus: According to Monroe in "Let Your Hair Down", he's real, and he's a Wesen called a Gefrierengeber that can survive in the cold of the North Pole.
* SaveThePrincess: {{Invoked}} and [[Conversed {{Discussed}}]] when [[spoiler:Juliette is kidnapped by a Daemonfeuer.]]
* ScienceMarchesOn: In-Universe. Graussen were originally believed to be human children possessed by a demon and later subject to a genetic mutation that gave them a feral, wesen-like condition. This led the Wesen Council to make these children "disappear." [[spoiler:Juliette figures out that it's really a parasitic infection that can be treated and Nick turns the information over to the Council's bag-man.]]
* ScrewTheRulesImDoingWhatsRight: Monroe is breaking all kinds of taboos by helping Nick, but he is not going to let that stop him from doing what he thinks is right. This point is made clear when, in Episode 9 ("Of Mouse and Man"), he's [[spoiler:ambushed by a group of creatures who beat him bloody and unconscious, then scrawl a Reaper scythe emblem on his car; Nick says he won't ask for any more help, but Monroe refuses to knuckle under to threats]].
-->'''Monroe:''' I'm not really a status quo kind of guy.
** Standard operating procedure for Graussen children is for the Wesen Council to make them disappear. Rosalee contacts the Council as she's obligated to do but when their representative shows up in town, Monroe alerts Nick instead and offers to help identify the guy, despite the risk to himself and Rosalee. (Nick tells him to stay put.)
* SecretWar: See Masquerade.
* SeldomSeenSpecies: A lot of Wesen are inspired by animals. While you have your usual lions, tigers, and bears, there are also some that take cues from more unique species. There are pufferfish, lamprey, porcupine, Saber-toothed cat, badger, otter, and gecko-like wesen. And while it's never been seen in the show, the books in Nick's trailer have images of a platypus wesen.
* SelfSurgery: In "Island of Dreams", a Wessen who had a chunk bitten out of his leg during a robbery gone wrong stitches up the wound himself.
* SerialKillerKiller: El Cucuy, basically a boogeyman wesen of Hispanic origin, comes to a region by hearing the cries of women in trouble because of the rampaging evil abound. It seeks to end the evil doers by murdering them. And it isn't just one. This is the operating style of the entire species.
* SexyCoatFlashing: In "Bears Will be Bears", Gilda seduces her boyfriend by suggestively opening [[PrettyInMink a fur coat she's wearing]] to reveal her lingerie-clad body.
* ShaggySearchTechnique: Averted, though to be fair, it is a cop-related show. Hank and Nick typically search for hidden stuff the way you'd expect.
* ShellShockedVeteran: In "El Cucuy" a man who keeps popping up at crime scenes is revealed to be a Marine who is suffering [=PTSD=] from his tours overseas. All he wants is to keep his neighborhood safe [[spoiler:so he goes and tries to kill a wesen who was causing trouble when he was released, as said wesen was innocent of the murders in the episode]].
** In "The Good Soldier" Frankie Gonzalez initially looks like an unhinged stalker-type who's willing to harass and murder over a grudge. [[spoiler:Subverted in that her PTSD was due to being raped and her attackers escaping justice. She only wanted them to confess to what they'd done. It was her former C.O. and one of the conspirators doing the killings.]]
* ShipTease: From the moment she showed up, this has been happening between Rosalee and Monroe.
* ShoutOut:
** In episode 1x06, a Blutbad, in other words a werewolf of sorts, by the name of [[MercyThompson Adam Hauptmann]] is mentioned.
** In Episode 11, they meet a friend of Monroe's, a [[BlackWidow Spinnetod]], named [[Literature/CharlottesWeb Charlotte]].
** Ariel Eberhart claims she got her dragon tattoo "long before [[Literature/TheGirlWithTheDragonTattoo that book]] came out."
** Episode 19 episode is titled [[LeaveItToBeaver Leave it to Beavers]].
** In "Happily Ever Aftermath", the name of the businessman that perpetrated the Ponzi-scheme is Bernard Eidekoff, which is reminiscent of real-life criminal Bernie Madoff, convicted of a Ponzi-scheme.
** The bigfoot investigators in "Big Feet" are named Patterson and Gimlin, after the [[http://en.wikipedia.org/wiki/Patterson-Gimlin_film Patterson-Gimlin film]].
** The Opening Narration in Season 2 is one big ShoutOut to Series/BuffyTheVampireSlayer.
** In episode 2x16 a video game designer uses the character alias of [[{{Farscape}} Aeryn Sun]].
** The title of the episode “One Angry Fuchsbau" is a shout out to “Twelve Angry Men”, a drama about a jury.
** Though the episode "Cold Blooded" draws most of its influence from the myth about alligators living in the sewers, Nick is able to find the MonsterOfTheWeek's hideout by following the sound of [[Literature/PeterPan several ticking clocks]]. Of course these are alligators and not crocodiles, but the connection is clear.
*** The ''wesen'' in question also bears more than a passing resemblance to [[{{Franchise/Batman}} Killer Croc]].
*** The Vambrace Nick uses to take on the Gelumcaedus [[Franchise/AssassinsCreed has the appearance of the Hidden Blades used by Assassin-trained agents.]]
** Nick, Hank and Wu are dressed in decomination clothes aside being accidentally exposed to some minor doses of radiation, which resulted in a {{Ghostbusters}} reference.
** In "Stories We Tell Our Young", Renard tells Nick and Hank that if anyone wants to reach him on an important matter, he told them that he'll be in "[[Series/AgentsofSHIELD Tahiti]]" for the meantime.
** The koschei wesen are a reference to the tales of Koschei the Deathless with a side-order of Rasputin the Mad Monk.
* SickEpisode: "Game Ogre" kind of functions as this for Nick, given that he spends two-thirds of it hospitalized after a fight with a siegbarste.
* SignificantAnagram: Trinket Lipslums in "Nameless". [[spoiler: Rumplestiltskin]].
* SingleTear: Monroe has one in "Over My Dead Body" [[spoiler:just before drinking the dead faint Zaubertrank]]. Easy to miss since it's not called out and the scene is more focused on [[spoiler:him trying to reassure Rosalee slash almost sorta tell her how he feels, despite the date they had before]].
* SinisterMinister: [[spoiler:One of Captain Renard's allies is a Catholic priest who serves as "God's Wrath" and will kill those who go against Renard's rule over the Wesen in the area.]]
* SinisterScythe: Seems to be the WeaponOfChoice for the Reapers of the Grimms.
* SoftGlass: ''Heavily'' averted in the case of [[spoiler:Catherine Schade]].
* SoreLoser: Fuchsteufelwild ''hate'' losing at games. [[spoiler: To the point where [[SignificantAnagram Trinket Lipslums]] would rather throw himself off the roof, rather than be caught and admit that Nick beat him.]]
* SoundtrackDissonance: In "Mr. Sandman," the titular song plays as background music while Andre's recently blinded first victim blunders around her apartment, crying and in severe pain, and ultimately pulls a bookshelf down onto herself and is crushed to death.
* SpiritualSuccessor: So Nick is essentially TheChosenOne who protects people from the forces of darkness, his mentor Aunt Marie is a librarian with a weapons cabinet and a giant book of demons (and she can kick ass). And the monsters have a GameFace that looks oddly familiar. And David Greenwalt is the executive producer. [[Series/BuffyTheVampireSlayer Remind you of anything?]]
** The premise (the monster hunter is the mythical creature to the mythical creatures) also draws heavily from ''Literature/IAmLegend'' (the original story not the movie).
* SpotTheThread: In "Blond Ambition" Theresa notices [[spoiler:Adalind!Juliette isn't the right Juliette when she doesn't recognize her and says she doesn't like bacon, when Juliette is an admitted bacon-addict]].
* SpyFiction: Most of the plotlines directly concerning the royals or Verrat tend to GenreShift into this, heavy Stale Beer flavor.
* StalkerShrine: Happens to Nick in "The Hour of Death" when he finds the bedroom of the Grimm vigilante where dozens of pictures of himself are posted all over the walls.
* StalkerWithACrush: Ariel Eberhart somehow manages to come across as this, even though Nick was the one stalking ''her'' (well, following her for a case, technically speaking). [[spoiler:Of course, it's all part of her plan]].
* StatusQuoIsGod: In-universe example. The Reapers don't take kindly to anyone messing with the status quo of the supernatural system and alliances. Nick's crossing lines and making certain allies is not well liked as a result.
* StepIntoTheBlindingFight: An episode had a [[AnimalMotif fly]] [[MonsterOfTheWeek Wesen]] capable of spewing a certain parasite into his victims' eyes which blinded them (and after a while the parasites would completely [[EyeScream eat out their eyes]]). After he blinds Nick, the Wesen later tries to use this to his advantage in an attack, but Nick's developed [[SuperSenses enhanced hearing]] and ends up winning.
* StockSoundEffects: Several of the over-the-top type, probably to enhance the "supernatural creatures out of folk tales" feel.
* StraightEdgeEvil: The villain of the pilot episode is a [[spoiler:soft-spoken mailman who wears loafers, fluffy sweaters and aprons and owns a cozy cottage in the woods. And eats people.]]
* StupidCrooks: The two kidnappers in "The Hour of Death" left hair samples of their victim, chloroform and the rag they used to apply it, and ''the victim's purse containing a wallet with her photo ID'' in one kidnapper's car. A bit of a subversion as by the time they find this evidence one of the kidnappers had been tortured into confessing and killed by a Grimm vigilante, and the other one was released from custody while Nick and Hank were being shown the evidence by the same vigilante who then killed him.
* SublimeRhyme: "Don't let your womb be your tomb."
* SuperpowerfulGenetics: With a magical element. The death of the previous generation passes on the powers to the next. Because Marie has terminal cancer, the abilities were passing to Nick a little at a time. Upon her death, though, the rest showed up.
** Though, this is questionable as it's revealed that [[spoiler: Nick's mother is still very much alive.]]
** Retconned slightly in the second season. Grimms are now said to receive their powers at a random age, although females gain theirs sooner than males. Marie's terminal cancer didn't so much cause Nick to inherit the Grimm abilities as make it imperative that she tell him what he needs to know while she still could.
** In "Stories We Tell Our Young" Nick and Hank get a primer in wesen genetics from Monroe and Rosalee but the GratuitousGerman obfuscates much of the meaning. Basically, same-type wesen-wesen pairings always produce wesen children. Wesen-human pairings have a 50% chance of producing a wesen child unless the human carries wesen genes (kehrseite-genträger), in which case it's always wesen. Pairings of different wesen types produce a special kind of offspring, which Monroe and Rosalee are very vague about. The term they use, ''vorherrscher'', implies that it's a matter of dominant genetic expression of traits.
* SuperSenses: A number of wesen have particularly keen senses, such as Monroe with his [[TheNoseKnows sense of smell]]. [[spoiler: As of "Mr. Sandman", Nick acquires super hearing, as a result of his body's apparent innate power to compensate for damage caused by Wesen attacks (in this case, being blinded)]].
* SuperpoweredEvilSide: Pierce Higgins, who's normally a relatively docile turtle-like Wesen, starts to randomly turn into a [[spoiler:Lowen]] and killing his competitors [[spoiler:who happen to be his friends on the Academic Decathalon team]]. [[spoiler: His mother experimented on his genetics in utero to make him better able to defend himself (as their people had been victims of VanHelsingHateCrimes in the past), and this was the result]].
** The Krampus from "The Twelve Days of Krampus" is a harmless photographer most of the time, but turns into the powerful monster that eats naughty children for a few days every year around Christmas. He has no memory or knowledge of what he's done during his "blackouts".
* SwarmOfRats: In "Danse Macabre", an unlucky music teacher becomes a meal for a pack of hungry rats, and a Reinigen can actually control them.
[[/folder]]

[[folder:Tropes T-Z]]
* TeethClenchedTeamwork: Nick and Angelina in "Over My Dead Body"
* TelevisionGeography: Portland is divided into five geographic sectors -- North, Northeast, Northwest, Southeast and Southwest. Every street name is preceded by one of these sector names (i.e., Northeast Tenth Avenue) except for Burnside Street which is labeled "East" or "West." East-west streets can run through two sectors of the city; the names of north-south avenues (which are numbered) can exist in up to four sectors of the city. Therefore, it's important to not only say the name of the street, but also the sector where it exists. In ''Grimm'', names of streets are given without their corresponding sectors. (Probably to keep viewers from visiting RealLife addresses.)
** in Episode 1x18 there is a brief shot of the city of "Mannheim, Germany" which is actually shot in another German city, Hannover. Glaringly obvious to anyone who has ever visited Hannover. Probably Mannheim didn't look German enough?
** In Episode 3x01 they claim that they can't stop a plane because "in a few minutes it'll be over international waters". Except... they're in Portland. And it's going to Austria. So no, it really wouldn't be. It doesn't help that MANY minutes later [[spoiler: the plane goes down in flames, but apparently still lands in America. So much for international waters?]]
* TerrorHero: Nick has been known to play on the murderous reputations of past generations of Grimms in order to intimidate Wesen into backing down or giving him information. Renard does this on occasion too, though not because he's a Grimm but [[spoiler: because he's both a royal and a zauberbeiste, either of which gives most wesen pause.]]
* TitleDrop: in the episode "Island of Dreams" the title turns out to be a term used for a Wesen OpiumDen, which is featured in the episode.
** The show title is said pretty much every episode, which is a given really.
** If an episode title is named after a wesen featured in the episode, this will inevitably happen.
** Eric Renard quotes both the show title and episode title in the Season 2 finale (Goodnight, Sweet Grimm), as he [[spoiler:closes a zombified Nick into a coffin.]]
* TitleOnlyOpening: All the first season. In the second season they added an opening.
* ThereShouldBeALaw: Hap in "The Three Bad Wolves" is surprised that it's legal for a Grimm to be a police officer. He is not the brightest guy.
-->'''Hap''': He's a cop ''and'' a Grimm? Is that even legal?
* TheThreeFacesOfEve: {{Genderflipped}} with the DeadpanSnarker[=/=]{{Adorkable}} Monroe, the seductive HandsomeDevil[=/=]TheCharmer Renard and the [[NervesOfSteel wise]] [[AlwaysSaveTheGirl and faithful]] boyfriend Nick.
** Played straight with the three main girl characters and the way they use their very similar abilities. [[{{Muggles}} Juliette]] [[BadassAdorable Silverton]] is the more vulnerable Child and knows only how to heal animals, and is thus unambiguously positive and not implicated in the main storyline. [[GeniusBruiser Rosalee]] [[SugarAndIcePersonality Calvert]] is the [[TheSmartGuy most cerebral of them all]], is both able to create potions to heal and to poison people, being in the same time good and involved in the main storyline, and Monroe's LoveInterest as the Wife of the trio. [[FemmeFatale Adalind]] is the Seductress, who has been seen using her powers only to poison, and is [[TheVillainMakesThePlot involved in the storyline]] as [[TheBaroness a seductive but harmful antagonist]].
* TheyDo: In "Good Night, Sweet Grimm" [[spoiler:Nick and Juliette finish reconciling their relationship with Juliette a full partner in the Grimm side of things, while [[BetaCouple Monroe and Rosalee]] consummate their own relationship.]]
* TheyLookJustLikeEveryoneElse: To anyone but a Grimm, that is.
* ThingsThatGoBumpInTheNight
* ThisIsNotMyLifeToTake: After successfully [[KillItWithIce freezing]] Volcanalis, Nick hands Markus Hemmings the sledgehammer so he can land the [[LiterallyShatteredLives killing blow]] on his wife's murderer.
* ThoseWackyNazis: AdolfHitler was a [[TheBigBadWolf Blutbad]] according to one of the producers.
* ToBeContinued:
** "Season of the Hexenbiest" which has "To Be Continued. Sorry."
** And also the season 2 finale "Goodnight, Sweet Grimm" which has "To Be Continued. [[BreakingTheFourthWall Oh, come on. You knew this was coming.]]"
** And the season 3 premiere, "The Ungrateful Dead" has "This ain't over yet."
** "The Wild Hunt" drops [[OhCrap "Oh #*@% !!!"]] before "To Be Continued..."
* ToBeLawfulOrGood:
** Nick runs up on this trope in "Beeware" when he has to protect Adalind from Melissa. In the eyes of the law, Melissa is a murderer, and he's a cop. In the eyes of the supernatural, Adalind is a Hexenbiest and Melissa a Mellifer, messenger and helper to Grimms. This time, Nick chooses the law.
** He faces this again in "Cat and Mouse" when [[spoiler:he let Ian, the head of the Resistance, go after Ian killed a defenseless man in front of Nick and had Monroe dump the body away from Rosalee's shop all to protect his friends. So in sum, he picked Good.]]
** And again in "Endangered", [[spoiler:when he allows the killer he'd been chasing all along to go free... because the death was accidental and the killer is a new father, whose family are all members of an endangered Wesen line.]]
* TooCleverByHalf: The Genio Innocuo, a Galapagos tortoise Wesen featured in "The Other Side." They're highly intelligent but extremely docile (thus allowing themselves to be hunted to near-extinction by highly prejudicial 19th-century Grimms), and in the present day, [[spoiler:a Genio Innocuo mother gives her son partial Lowen DNA to enhance his fighting ability, only to cause severe split personality that leads him to murder his classmates when they challenged him academically and not remember doing so.]]
* TooDumbToLive:
** In "El Cucuy" it is revealed the Wesen Hollintier, a jackal/neanderthal-like type who have big egos but not brains, were around in ancient Egypt. The ancient Egyptians could convince them to guard the tombs of Pharaohs ''from the inside'' because the wesen thought it to be a ''promotion.''
** In "Blond Ambition" Weston Steward [[spoiler:shoots Renard in Nick's house with Trubel as witness. He then chases her down and -- instead of [[WhyDontYouJustShootHim just shooting her]] -- puts away his pistol and woges to finish her off with his bare hands. Whereupon he discovers the hard way that she's a Grimm and winds up on the business end of her machete.]]
* TookALevelInBadass:
** Nick several times.
*** In "Organ Grinder", for the first time, we see him intentionally threaten creatures with his status as a Grimm and exactly why that means they should be treading ''very'' carefully around him. He also pointedly warns the Geier in the clinic that he's ''NOT'' being a cop at that moment.
*** In "Last Grimm Standing" its revealed that Grimms have superior strength to that of ordinary humans, allowing Nick to easily defeat an adversary that several well-trained Wesen failed to do. Monroe's comment about digging down deep and channeling previous generations of Grimms could indicate that they might potentially have more abilities.
*** In "Leave it to Beavers", Nick ends up [[spoiler:killing ''two'' Reapers tasked with eliminating him. He sends a parcel containing their severed heads back to their handler in Germany, along with a note]].
---->'''[[spoiler:Nick]]:''' [[spoiler:Next time, send your best.]]
*** In "Season of the Hexenbiest" Nick takes out [[spoiler:four Verrat soldiers]] with a kanabo and only nominal assistance from Monroe.
---->'''Monroe:''' So do you wanna arrest these guys or what?\\
'''Nick:''' Or what.
** Juliette, repeatedly. The first season gives her a storyline where she takes shooting lessons. In Season 2, she [[spoiler: becomes aware of wesen and decides to build up her tolerance by getting her friends to woge for her]]. And in Season 3, she has clearly been taking self-defence lessons and moves up to CombatPragmatist ActionGirl by once again fighting a [[spoiler: Klaustreich]] intruder who has incapacitated Nick, kicking his ass [[spoiler: even when he's in full woge]].
* TragicVillain: Spinnetod females. Due to the demands of their species, they're cursed to age incredibly fast (starting at puberty) with the only way to avoid this being to kill and eat young men... which may include spinnetod males.
* TrailersAlwaysSpoil: The promo for "The Wild Hunt" [[spoiler:shows Monroe proposing to Rosalee.]]
* TriggerHappy: The bad guys in “Island Of Dreams” only meet the ‘shoot at the slightest provocation’ part of the trope description.
* TrueCompanions: Nick, Juliette, Monroe, Rosalee, and Hank look to be shaping up this way. Not only is a Grimm friends with the beings who were raised to fear him, Hank and Juliette are two normal people who have accepted their friends, not run away in fear or try to kill them. This group is truly a rare find.
* TrueLovesKiss:
** Played with at the start of season 2. For Juliette to wake from her coma, she needs a kiss from someone pure of heart... and her long-time boyfriend is one of the nicest, most genuinely decent guys you will ever meet, constantly visiting her in the hospital. It ends up being Renard, a virtual stranger to her--but also a prince, apparently another requirement--who takes a potion to make him pure enough of heart to deliver the kiss himself. This has major implications later in the season, as breaking Adalind's curse causes both Renard and Juliette to become obsessed with each other.
** Played straighter in "Kiss of the Muse" although there's not an actual kiss. [[spoiler: Nick is infected by the kiss of a Wesen called a musai and becomes obsessed with her, for which there is no known antidote. Juliette recovers her memory in time to reach out to him and cure him.]] Might be more accurately described as True Love's HeldGaze.
* UndergroundRailroad: For Wesen who are trying to escape the Old World controlled by [[AristocratsAreEvil The Seven Families]], there is this as a means of escape in United States.
* UnreliableNarrator: Farley Kolt in “Three Coins In A Fucshbau”. He seems to be on the level when he says that [[spoiler: he and Aunt Marie where engaged before she had to leave him to take care of Nick]] but in light of the fact that he [[spoiler: was after the coins for himself]], how much he can be trusted is thrown into question.
* UselessSecurityCamera: Subverted. They couldn't find the perp with the security cams, but they were able to identify the murder victim and the people standing closest to her so they could question them about the crime. They were also able to nudge an uncooperative witness by reminding him he'd been caught on camera.
** Of course in "Three Coins", the camera didn't help much because [[spoiler: the perps ripped it out of the wall and took it with them.]]
* UrbanLegend: "Cold Blooded" isn't based on a fairy tale, and rather the popular tale that there are alligators living in the sewers of various big cities. The wesen in question, gelumcaedus, guarded the aqueducts in ancient Rome. When the empire fell, they retreated to the underground pipes to avoid persecution, and ever since have dwelled in the pipes and sewers below cities.
** Their isolation also explains why they still use the old Roman name for Grimms, "Decapitare" (i.e. "decapitator").
* [[VegetarianVampire Vegetarian Wesen]]: Wieder Wesen. Monroe is one now, but wasn't always. Charlotte in "Tarantella" is an example of what happens to Spinnetod women if they succeed in resisting the urge to kill every five years. The result is [[YoungerThanTheyLook rapid aging]].
* VerbThis: "Tweet this" from Doug the Mellifer.
* VillainHasAPoint: The ''Beati Paoli'' in "Once We Were Gods." Although they use theft, arson and murder to achieve their ends, they're not wrong that looting ancient cultures and desecrating remains are disrespectful to the dead and the native cultures, even in the name of science.
* VisualPun: Nick and Monroe at a dog park.
* WackyMarriageProposal: [[spoiler: Monroe proposes to Rosalee in "The Wild Hunt" by making a cuckoo clock that pops out with a ring and asks, "Will you marry me?"]]
* WalkingSwimsuitScene: The Naiads.
* WallOfWeapons:
** Nick has one in his trailer. Monroe finds it--and the rest of the Grimm 'lair'--to be appropriately cool and scary from his perspective as a blutbad.
** Later repeated when Nick shows Hank around the trailer and admits that he actually ''does'' have a crossbow.
--> '''Hank''': Are you kidding me?!
* WelcomedToTheMasquerade: Nick is a Grimm and when he comes into his powers, his dying aunt did not have much time to explain to him what that entails or teach him about the world he is about to become part of. It is up to Monroe, a Blutbat Wesen, to become Nick's mentor in Wesen matters. Later on Nick brings in his Muggle [[spoiler:partner Hank]] and [[spoiler:fiance Juliette]] into the Masquerade because they are put in danger by not knowing what is really going on.
* WellIntentionedExtremist:
** Melissa and her minions, killing Hexenbiests because they're evil.
** El Cucuy, basically a boogeyman wesen of Hispanic origin, comes to a region by hearing the cries of women in trouble because of the rampaging evil abound. It seeks to end the evil doers by murdering them. They see nothing wrong with their actions.
* {{Wendigo}}: Your standard [[ImAHumanitarian cave-dwelling cannibal]]. Likes to eat their victims and bury their remains near their lairs.
* WhamEpisode: "Three Coins in a Fuchsbau." [[spoiler:Aunt Marie was once engaged to a Wesen, but had to break it off when her sister (also a Grimm) was killed by another Wesen, who had stolen coins she was protecting--coins responsible for Nero, Caligula, and the Third Reich]]. Also, [[BeethovenWasAnAlienSpy Hitler was a Wesen.]]
** "Woman in Black." [[spoiler:Adalind has afflicted Juliette with some unknown poison. To get her to seek medical treatment, Nick tells her everything, but she falls unconscious before he can show her definitive proof. Hank is starting to GoMadFromTheRevelation after seeing both Monroe in his Blutbad form and a Wildermann turn back to human when he died. Oh yeah, and Nick's mother is alive.]]
** "Season of the Hexenbiest." [[spoiler:Monroe discovers Renard and Juliette's feelings for each other and tells Nick. Adalind returns to Portland and has Hank beaten severely enough to be hospitalized. She then learns about the trailer from Juliette and passes this information to Renard. Nick and Juliette break up and Nick moves out of the house. Monroe reveals Renard to Nick as Juliette's obsession. Renard discovers the trailer.]]
** ''Face Off''. [[spoiler: Nick and Monroe find out that Juliette and Renard are under a spell and Renard is the Royal in Portland. Renard is in an alliance with the anti-Royal rebellion. Renard finds Nick's aunt's key but, instead of giving it to Adalind, comes clean to Nick and proposes an alliance. And Adalind is pregnant.]]
** "Goodnight, Sweet Grimm". [[spoiler: Eric comes to Portland [[AndThenJohnWasAZombie And Nick gets turned into a zombie.]]]]
** "Blond Ambition", the season 3 finale has gotta top all of them. [[spoiler:All the guests at Monroe and Rosalee's wedding learn that they're friends with a Grimm, Adalind takes away Nick's Grimm abilities and buggers off to Europe on the promise of Renard's cousin to return her baby ([[ManipulativeBastard whom he doesn't actually have]]), Captain Renard is on the edge of death due to having been shot by a Verrat agent, Trubel beheads the guy that shot Renard and calls the police, leading to Wu finding some of Nick's books and learns about Grimm and Wesen.]]
* WhamLine:
** From "Love Sick".
--->'''Adalind:''' [[spoiler:You killed me.]]\\
'''Nick:''' [[spoiler:You don't look very dead.]]\\
'''Adalind:''' [[spoiler:I'm human.]]
** From "Woman in Black".
--->'''Woman In Black:''' [[spoiler:Nick. Nicky, it's me.]]\\
'''Nick:''' [[spoiler:Mom?]]
** From "Nobody Knows the Trubel I've Seen".
--->'''Monroe:''' [[spoiler:She's a Grimm!]]
* WhamShot: In the season 3 finale "Blond Ambition" [[spoiler:Wu sees one of the Grimm books showing a wesen and a grimm beheading it. While standing in Nick's house where someone has been decapitated.]]
* WhatHappenedToTheMouse:
** In "Let Your Hair Down", the last we see of the doggie-wash guy, he's tied up in a basement.
** So, as of the end of "Tarantella", there's a prematurely aged young woman in jail who is missing no fingers, but the cops have a detached finger that matches her DNA. How did the law process this one?
* WhatMeasureIsANonHuman[=/=]VanHelsingHateCrimes: Subverted. Unlike some of [[Series/{{Supernatural}} its brethren]] in the genre, Nick is fine with letting supernatural creatures live their own lives as long as they're not breaking the law, and so far has treated them as he would human beings in comparative situations. This has come to shock some of them as this approach seems unheard of for a Grimm (on the other hand, Marie very specifically said "Hunt down the bad ones"). Conversely, it turns out that some of the supernatural creatures are either (usually) harmless and not involved in any real trouble or are allies of the Grimms. The former still tend to be wary of Nick while the latter tend to be surprised that Nick seems to ignore the traditional feuds. Nevertheless, the reputation of the Grimms is enough that most creatures that recognize Nick instantly expect him to kill them on the spot.
** The peaceful ones that get to know him, however, ([[spoiler: Monroe, Rosalee, the Beaverfolk]]) often appreciate having a Grimm as an ally, because that gives them an edge over their more AxeCrazy counterparts in Wesen society, especially if they were traditionally on the lower end of the StatusQuo.
*** Also comes in handy when [[spoiler: a very old school, very militant Grimm shows up.]] Nick's rapport with them is [[spoiler: probably the only thing preventing the wesen community from being any more panicked than it was.]]
** On the other side of things, [[spoiler: Nick's mom has trouble with this as well since she was raised under the belief that all wesen were dangerous and should be killed (well, the non-allies anyway). So it's justified that she has trouble understanding Nick's relationship with Monroe and Rosalee, but given the clear signs of trust, she's at least willing to accept it if not understanding it.]]
** One episode had Nick and Hank looking up a prior Grimm's journal entry regarding a race of turtle-like wesen, who were described as very intelligent and peaceful. The very next sentence was about how their docile natures made them easy to kill.
** "The Hour of Death" deals with the seeming reemergence of a particularly brutal sect of Grimms whose exploits are what earned the Grimms their place as Wesen boogeymen. Apparently back in the day they would go from place to place torturing and branding any Wesen they come across, regardless of whether they were innocent men, women or even children.
** Rosalee is highly intrigued by the contents of the trailer, right up until Monroe reminds her that it's all dedicated to the hunting and killing of their kind.
* [[WhyDidItHaveToBeSnakes Why Did It have to be Rats?]]: "Danse Macabre."
* WomanInBlack: The titular character of, well, "The Woman In Black".
* WitchWithACapitalB: In "Season of the Hexenbiest" we have this line, with a slight emphasis put on the last word.
-->'''Nick''': "I guess you don't have to be a Hexenbeist to be a witch."
** In the episode "Nobody Knows the Trubel I've Seen", Viktor refers to Adalind as "the Hexenbitch".
* WomanInWhite: La Llorona, the titular ''something'' in "La Llorona". Nobody's quite sure what she is, though the legend she's based on has her as the ghost of a woman who drowned her children after her husband left her for a younger woman, but she appears as a beautiful woman in a long white dress.
* WomanScorned: A Blutbad reverend is accused of stealing from his Seelengut church and trying to pin it on the accountant, but his Seelengut girlfriend vouches for his alibi. Then she finds out that he's knocked up another woman in the flock. [[spoiler: She turns him in to the irate flock, who gang up and beat him to death, and she and the other woman go to [[TropicalEpilogue live the good life]] on the money he stole.]]
** Adalind, especially in Season 2.
* WouldHurtAChild: Whenever a case of Grausen--a rare phenomenon observed in children, theorized to be demonic possession or some kind of mutation--is reported, the Wesen Council takes quick and decisive action to make the victim "disappear". Since Grausen-afflicted children who are allowed to grow up become terrifying psychopaths, it's easy to understand why they take such a hard line. However, when Alexander, a panther-like Pflichttreue who loyally serves the Council, is sent to deal with one such case, it's very clear that he doesn't ''want'' to harm a nine-year-old boy.
* WouldntHitAGirl: In ''Face Off'', Season 2, there's a lot of violence between [[spoiler:Renard and Juliette, but almost all of it is directed against Renard: He get's pushed, bitten, pistol-whipped and shot at. Renard himself is close to loosing control, but the worst he does is grab Juliette or push her away.]]
* WrongGenreSavvy: Nick mixes Blutbaden with werewolves, and asks if he might need silver bullets. Granted, he was just told that he would be harder to smell if he rubbed wolfsbane on his clothes.
-->'''Monroe''': What, are you an ''idiot''?
* YankTheDogsChain: In "The Bottle Imp," there's a scene where Juliette suddenly regains her memories while at the sink and claims to believe that Nick is a Grimm. Then it [[AllJustADream turns out to be Nick's dream]].
* {{Yandere}}: Ariel Eberhart from "Plumed Serpent" quickly demonstrates an intense obsession with Nick.
* YouAreWhatYouHate: [[spoiler: In "The Hour of Death" Nick suspects that another Grimm is killing Wesen in Portland. It is actually a Wesen who is in denial about what he is and believes that all Wesen must be killed. To provide context since it isn't explained on the show, the person in question is a Lebensauger - a Wesen based off lamprey eels. Complete with sucker mouth and eel-like skin. The Grimm wiki provides more information.]]
* {{Youkai}}: Spinnetods are the inspiration for Japanese Jorogumo, or spider-demons.
* YouCannotGraspTheTrueForm: Munroe's explanation of why it's a really bad idea to show [[{{Muggles}} normal humans]] a Wesen's true form. He said that people can handle fantastic concepts like angels, demons, God, and the Big Bang because they don't experience it firsthand. People seeing living myths with their own eyes, on the other hand, might very well make the recipient...
** GoMadFromTheRevelation
** It seems that people whose sanity withstands the initial shock tend to go mad because they ''think'' they're going crazy. [[spoiler:Hank]] starts [[SanitySlippage slipping]] over the several weeks after he sees two Wesen's [[GameFace true forms]]. [[spoiler:Nick has to talk him down from shooting his own goddaughter in a blind panic when she accidentally reveals her GameFace, but once he's been given a quick explanation, he quickly recovers from his previous SanitySlippage and is very glad to discover he's not insane.]]
*** One of Hank's goddaughter's abductors tries to invoke this trope on Nick and Hank by showing the two interfering cops his GameFace, only to discover that [[spoiler:Hank is already aware and has a handle on it and]] Nick is a Grimm. Cue OhCrap.
** A mild version occurs in "La Llorona" when [[spoiler: Nick is fighting the titular character. Since she/it isn't a Wesen, isn't human, and at least some of the time, isn't even a physical being, Nick is clearly taken aback when he discovers this. It seems like he almost forgets that he's ''underwater''.]] Like Monroe noted before, people can handle some things but when they encounter other things up close and personal, it can be a little shocking.
* YouGoGirl: Juliette has this storyline going on, which increased her popularity drastically. She is currently insisting upon being reognized as a capable person (and demonstrates that she is one) and wants Nick to explain things to her instead of over-protecting her. Notably averted with Rosalee, who immediately became accepted as a competent ally and member of the team.
* YouHaveOutlivedYourUsefulness:
** Renard to [[spoiler:Adalind]] sort of. It is more that she not only failed to get the key, but lost her powers. Sean doesn't kill her, just kicks her out of his uses.
** Sean also says this of the Lowen gladiator in "Last Grimm Standing".
** When the head of the Verat failed [[spoiler:in getting the baby back, failed in getting Adalind, killing a resistance member, and lost six agents despite knowing where the Resistance was taking Adalind and baby]] Viktor told him his services would no longer be required and he is dealt with.
* [[YouKilledMyFather You Killed My Parents!]]
* YouKillItYouBoughtIt: What happens to Angelina in "Over My Dead Body" when she kills a Skalengeck attempting to rape her. It turns out that the Skalengeck was hired to kill Monroe and since she killed him, she was told she would be the one to do the deed instead.
* ZanyScheme: The scheme Nick, Hank, Monroe, Rosalee, and Bud pull in "One Angry Fuschsbau" to get [[spoiler: the Ziegevolk lawyer]]'s sweat to create an antidote that will nullify his ability to tamper with the jury, then get him to ingest that antidote. The craziness of it is later lampshaded when their target walks in on them having a celebratory dinner afterwards and Nick just tells him, [[RefugeInAudacity "Try telling that to a jury."]]
* ZombieApocalypse:
** The Yellow Plague is effectively this for Wesen, though they're not actually dead just hyped up on adrenaline. And boils, sores, and other things. Fortunately, it's curable.
** A variation occurs in the two-parter finale of Season 2. A pufferfish Wesen (Cracher-Mortel, French for "deadly spit") called Baron Samedi can spit bright-green venom into people's faces and put them into a deep death-like coma. When they awaken, they are basically voodoo zombies under the Wesen's command. The zombies (who aren't actually dead) also double as the rage zombies of the ''Film/TwentyEightDaysLater'' series.
