11[[quoteright:217:https://static.tvtropes.org/pmwiki/pub/images/grissom-quitte-experts-L-1_2509.jpg]]
12-> Played by: Creator/WilliamPetersen
13%%* AgeGapRomance: With Sara.
14%%* BadassBookworm
15* BerserkButton: Drug dealers, especially those who sell to young people, and scientists who sell their integrity for personal gain.
16** Anyone who tries to hurt Sara. Pity that didn't include him.
17** InUniverse, he cites three Berserk buttons:
18---> '''Grissom''': "There's three things I got a real problem with: Guys that hit their wives, sexual assault on children and the scum that deal death to kids."
19* BrokenPedestal: Both his old professor and a colleague he wrote a study with became, to quote him, "guns for hire," [[SellOut selling their forensic skills]] to help rich guilty clients beat the rap.
20* BunnyEarsLawyer: He quotes Shakespeare, loves crossword puzzles, and races cockroaches for fun.
21* TheBusCameBack: He returns to the show after a while off-camera for the GrandFinale.
22* CanNotSpitItOut: His feelings for Sara in the first couple of seasons, even being so unsure about a possible commitment to the point where he rejects her initial advances. He's likewise extremely secretive about his hearing difficulties when he began to develop his mother's condition.
23* CasualKink: Sara asks Grissom to restrain her with duct tape (as part of testing a theory about a crime); before joining her in the lab, Grissom cheerfully asides, "I ''love'' my job!" His close but platonic friendship with [[{{Dominatrix}} Lady Heather]] doesn't make things any better.
24%%* CoolOldGuy
25* DramaticIrony: In the first PC game’s fifth case, ''Leda’s Swan Song'', Gil is left in a storage locker to be consumed by flesh-eating larvae. The irony comes in when you add Grissom’s profession in entomology.
26* EarlyInstallmentWeirdness: He's noticeably different in the first half of season 1, shown to be more light-hearted and emotional. It takes until "Face Lift" late in season one for it to really be shown he's not great with people; and then in season 2 he starts developing into his TheStoic persona more. To the show's credit, they worked this into Grissom's CharacterDevelopment, changing the character more as they delved deeper into his hearing loss.
27* AFatherToHisMen: His paternal leadership style, especially visible with Greg, Nick and Warrick [[spoiler:especially right before Warrick gets killed, and afterwards]].
28* {{Flanderization}}: In regards to his [[TheStoic stoicism]]. In the first season, he was prone to bouts of anger (once slapping a coffee pot out of Ecklie's hand, enraged) and happiness (even--gasp--smiling! With teeth and all!). By Season 3, his character was shaped into being level-headed at all times, even in normal conversation. Justifiable in that he starts to retreat emotionally during his struggle with his hearing loss.
29* FriendToBugs: He's an entomologist who not only studies bugs, but also protects them. He has four roaches named John, Paul, George and Ringo, and races them for fun. In one ep, he tells a subordinate to be sure and feed the bugs they collected at a scene. In another case, he asks two exterminators if it bothers them that their job requires them to kill living creatures. One just stares at him; the other replies, "What kind of question is that?"
30* GameOfNerds: He's a scientist who likes baseball.
31* JarOfTheBizarre: He eeps various insect specimens in his office, but among his collection is also an irradiated fetal pig in a jar. When he leaves the Crime Lab, he gifts it to David Hodges, who later returns it to Gil's office (which a few of the other [=CSIs=] are sharing by then) and says "This belongs in here."
32* InnocentlyInsensitive: His distant approach to social life leads him to sometimes saying the wrong things without realizing it, specifically to Sara before they dated, much to her frustration (she nearly quits over it).
33* IntelligenceEqualsIsolation: Especially in the earlier seasons. Despite his intelligence and expert grasp of human nature, Grissom leads a very isolated life, and rebuffed most opportunities of interaction outside of the workplace. He even turned down Sara's initial dating requests in Season 3.
34%%* LoveRealization: Mixed with WhamLine seen below.
35* MarriedToTheJob : For most of the series, at least until he marries Sara. Catherine used to tell him to take his head out of his microscope once in a while.
36* NotThatKindOfDoctor: He's an entomologist, not a medical doctor.
37* PapaWolf: Pretty much the only way to get him riled up is to either threaten one of his teammates, especially Sara, or do anything to endanger children
38* PlatonicLifePartners: With Catherine. They are obviously best friends, but there's also no hint of sexual chemistry between them.
39* PutOnABus: After season 9.
40** TheBusCameBack: He does have a cameo in season 12's "The Two Mrs. Grissoms," and returns at last for the series finale, which originally aired in September 2015.
41* QuipToBlack: Famous for it -- [[TheyChangedItNowItSucks used to be the]] TropeNamer
42%%* SarcasmFailure: When he doesn't use the above.
43%%* ScienceHero
44%%* SeekerArchetype
45* SeriousBusiness: Racing cockroaches. One of the first times we see him take some time off and put Catherine in charge is when he goes to an entomology conference, and he's most excited about the cockroach races. It doesn't go so well ("Stage fright").
46* SexIsInteresting: Grissom tells Lady Heather he finds all kinds of non-traditional sexual practices fascinating.
47* SilverFox: Despite his nerdiness and aloofness, he still gathers a lot of female admirers (in-universe and out), even when he shies away from the unwanted attention. He had no problems getting dinner dates when he actually sought them out.
48%%* TheSmartGuy
49%%* TheSpock
50* SurprisinglyRealisticOutcome: One early episode has him investigate a friend of the sheriff's as a murder suspect in an apparent suicide, wrongly as it turns out. Grissom swiftly finds out that no amount of being the force's BunnyEarsLawyer will excuse his political cluelessness.
51-->'''Sheriff Brian Mobley''': In other words, you made a suspect out of an innocent man.
52-->'''Grissom''': Obviously, that wasn't my intent.
53-->'''Mobley''': [[SarcasmMode Oh, good]]. Then maybe you'll want to bring that up in the newspaper article.
54-->'''Grissom''': What are you talking about? What newspaper article?
55-->'''Mobley''': The one I'm arranging for your public apology.
56-->'''Grissom''': I'm not making an apology.
57-->'''Mobley''': Oh yes, you are! You don't go after a friend of mine, sully his reputation and then walk away. [[WhatTheHellHero Actions have consequences, Gil. Even yours]].
58* TeamDad: To the boys more than Sara ([[{{UST}} obviously]]), but especially to Warrick and Nick.
59* WhamLine: For seven years, fans noticed an underlying degree of tension between Grissom & Sara, leading them to devise a term for it, "GSR," short for Grissom Sara Romance. In the Season 7 finale, it finally comes to the forefront when he realizes the extent of the Miniature Killer's revenge:
60->''"This girl holds me responsible for the death of Ernie Dell. I took away the only person she ever loved, so she's gonna do the same thing to me.'"''

64[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/catherinewillows_5780.bmp]]
65->Played by: Creator/MargHelgenberger
66
67* ActionGirl: She can stand up for herself when she needs to.
68* AlphaBitch: She reveals in one episode she was like this in high school. Even as an adult she's a bit of a LovableAlphaBitch.
69* BigSisterInstinct:
70** While they aren't related, she seems to feel this way towards Greg (who's about 20 years younger). For one, she seems the most upset when he is nearly beaten to death in "Fannysmackin."
71** When she comes back for Season 2 of the revival, she takes young CSI Penny Gill under her wing, convincing her to express her ideas more often as they are usually good ones.
72* TheBusCameBack: Like Grissom, comes back to Vegas for the series finale case, which starts at the casino she inherited, and decides to stay.
73%%* DeadpanSnarker
74%%* FakingTheDead: With D.B. to escape the bad guys before her departure.
75%%* FieryRedhead
76* GoodBadGirl: Mostly an InformedAttribute, as we only see her have a one night stand once, and she ends up calling it off before they actually have sex.
77* HeroicBastard: It's established early on that she was raised by a single mother, but it's only later that she learns her father is [[spoiler:Sam Braun, who leaves her a chunk of his casino after he dies]].
78* MamaBear: Messing with her daughter? Big mistake. The same applies to her team members.
79* MsFanservice: She used to be a stripper, way back in the day (and not an OldShame for her, even when a DA tries to use it against her in court). She has a couple of ToplessnessFromTheBack scenes and an interrogation where she unbuttons her blouse every time her suspect gives her an answer.
80%%* OfficialCouple: With Vartaan. For a while, anyway.
81%%* PlatonicLifePartners: With Grissom.
82* PutOnABus: Season 12, when she joins the FBI.
83* RevengeBeforeReason: Her automatic hatred towards registered sex offenders and anyone she even suspects of being a child abuser.
84** The long version: Catherine has several times had a very strong reaction to cases where a little girl is the victim, to the point where she will allow her own emotions to cloud her judgement. It is hinted this is because she is the mother of a young girl. Her emotions have caused her to severely jump the gun when it comes to a suspect and showing no hesitation to add her own verbal disgust and disbelief towards a suspect when they tell her their side of the story. Sara even once {{lampshade|Hanging}}d this by snarking that it was "fun" to hear Catherine's theories rather than process the actual evidence. Ironically, every time she has let her emotions take control of a case like this, whom her hatred is focused towards has always turned out to be a mere victim of "being at the wrong place at wrong time," shown by the evidence they were in no way involved with the case, but by the time that is revealed she often has completely ruined said guy's life.
85** ''[[{{Deconstruction}} Brutal]]'' case in point being Leo Finley from "A Thousand Days on Earth." She believes he is a child molester because of his name on the Sexual Predator Watch List though he was only there because of an incident where he got high on hallucinogenics and walked out naked in front of a bus full of children. After the man's fiance finds out about his past (through Catherine vindictively outing him) and that he is using an assumed name, she kicks him out of the house and then gets him fired by telling his boss. The man walks up to Catherine in the parking lot after this, threatening to shoot himself in the head on her front lawn one day, even calling her a "blonde Nazi bitch" when she [[BlatantLies insists]] she was [[JustFollowingOrders just doing her job]]. In her defense though, Finley did build his relationship with his girlfriend on a lie and lying on a job application about your name and being a felon warrants being fired.
86* ScareEmStraight: In response to Lindsey's reckless hitchhiking, her mom drags her into the morgue to view a dead hitchhiker (to Dr. Robbins' disapproval).
87* ScrewTheRulesIHaveConnections: Her being Sam Braun's daughter has gotten things done with her superiors at least once, even after his death.
88--> '''Brass''': Unbelievable! Sam Braun has more influence dead than I do alive!
89* ShipTease: With Warrick, up until his marriage. She even refers to the event as the "end of a fantasy".
90%%* SingleMomStripper: Retired.
91* StacysMom: Gets attention from younger men as well as those her own age.
92%%* TeamMom
93* UnwittingPawn: Catherine meets an old friend of hers who believes that her abusive husband (who is the president of a private military contractor) is targeting her. Knowing the husband's shady deals overseas, Catherine recommends her friend a lawyer who can protect her. Weeks later, the lawyer's firm is attacked by a group of hitmen and Catherine's friend as well as the FBI agent assigned to protect her are killed and Catherine herself is eventually targeted. [[spoiler:It is then revealed that the whole thing was set up by the friend who faked her death in order to frame her husband and Catherine (who will have the motive to do so) will be the scapegoat]].
94* VitriolicBestBuds: Downplayed, but she seems to have a fair amount of friction with Sara, especially in the early seasons. The reason for this isn't entirely clear, but it's implied they both have feelings for Grissom. Despite this, they are still basically friends, and it shows even in the early episodes, as there's one where Catherine is [[OOCISSeriousBusiness notably disturbed by the crime of the week]] and Sara [[PetTheDog makes sure she's ok.]]
95* WellDoneSonGuy: Old-school casino owner Sam Braun, who is shifty to say the least.

103* BuriedAlive: Happens to him when he's kidnapped in "Grave Danger."
104* CurtainsMatchTheWindow: Dark brown hair and eyes.

106* FriendToAllChildren: To the point that the other [=CSIs=] automatically defer to him when a child becomes involved.
107* HeroesLoveDogs: He adopts a former police dog in Season 13.
108* HollywoodHealing: He doesn't wind up with any scars after having had lots of fire ant bites.
109* ManlyTears: Nick cries several times over the course of the show, and it serves to highlight his empathetic nature.
110%%* MrFanservice
111%%* LanternJawOfJustice
112%%* NiceGuy: Undoubtedly the nicest person on the team.
113* PornStache: For a while, before he has enough of everyone's justified ribbing.
114* PutOnABus: To run the San Diego crime lab in the season 15 finale, though it takes him a while to decide [[spoiler: what with Finley in a coma and all, but DB assures him it's what she would want]].
115%%* ShirtlessScene
116%%* SouthernGentleman
117* TaughtByTelevision: "I watch the Discovery Channel," was one of his regular comments, back in the days when you [[NetworkDecay learned things from the Discovery Channel]]. He switches to Animal Planet once or twice.

127* FatalFlaw: His gambling addiction and all of the problems that come with it.
128* TheGamblingAddict: His addiction gets him into trouble early in the series, though he gets better.
129* GeniusBruiser: He's the largest and most physical of the original team, but that doesn't stop him from being a trained Audio/Visual expert who can count cards in his head.
130* KilledOffForReal: [[spoiler: Shot in the throat by Undersheriff Jeffrey [=McKeen=].]]
131* OutOfFocus: Gets hit with this hard and ends up being one of the least developed members of the cast.

139----
140* AgeGapRomance: With Grissom; the actors are 16 years apart in real life. Not that it matters to Sara, who openly admits to having a thing for silver foxes.
141* AlliterativeName: Sara Sidle.
142* BoyishShortHair: In most seasons she has rather short hair, with a bit of a [[TheSixties 60's]] aesthetic.
143* BerserkButton: Domestic violence, especially spouses murdering each other.
144%%* BrokenBird
145* CommutingOnABus: As of Season 10, she's on the line...she's listed as a series regular, but only appears in a certain number of episodes per season.
146** TheBusCameBack: Returns to ''C.S.I.'' full-time in Season 11, and remains aboard for the rest of the show's run.
147* DarkAndTroubledPast: Her mother killed her father, who was abusive to both her and her mother. She ended up in foster care.
148%%* FreudianExcuse
149* HintDropping: Tries this as a tactic while attempting to court Grissom. She once tells Hodges (who is fretting about a possible grey hair) that she finds grey hair rather sexy, ''while standing next to Grissom''. Eventually, she point-blank asks him out, which he refuses. After a couple of more years, he eventually comes around to GladYouThoughtOfIt.
150%%* HotForTeacher: see above
151* JerkWithAHeartOfGold: She often comes across as gruff and bad tempered, but she cares a lot about the victims and her friends.
152%%* TheLancer
153* TheMaidenNameDebate: She still uses "Sidle" now that she is married to Grissom. [[spoiler: They separate in Season 13, making the question seem moot, but get back together again in the finale.]]
154* MarriedToTheJob: At least until she marries Grissom. [[spoiler: Divorced by the time the bus comes back; back with him by the end of the series finale.]]
155* PutOnABus: She's taken a round trip, having come back to assist the team when they're short-staffed in season 10.
156%%* RelationshipReveal: With Grissom.
157* SecondEpisodeIntroduction: Comes in to help the team per request of (who else?) Grissom in the second episode following the death of the NaiveNewcomer and stays on board.
158* {{UST}}: For YEARS with Grissom before Season 6 ends with the [[RelationshipReveal above trope]].

164* AscendedFanboy: From "CSI Wannabe" to actual CSI. He started working as the DNA tech before going into the field.
165* BreakTheCutie: He becomes noticeably more mature after getting beaten to near death in "Fannysmackin'".
166* CasualKink: Has dabbled in every fetish under the sun, including latex wear, S&M, and even [[ChubbyChaser plus-size women]]. This is a man who likes variety.
167* CoolTeacher: Tries to be this in his revival appearances, despite the [=CSIs=] already knowing much of what he tells them
168%%* DeadpanSnarker
169%%* DelinquentHair
170* ExpositoryHairstyleChange: Shortly after becoming a CSI he stops sporting his normally wacky hairstyles, to show how he's matured.
171* GeniusDitz: In earlier seasons. While he does act like an idiot, he's very good at his job and has extended knowledge on coin collection and Old Vegas.
172* HehHehYouSaidX: In "A Bullet Runs Through It", an otherwise very serious episode, Grissom tells him to analyze the position of skid marks. The second Grissom leaves Greg chuckles, "He said skid marks."
173* HesBack: Returns to CSI work in Series 2 of the revival, specifically thye second half when Max needs an extra hand at the lab.
174* TheIntern: He was sort of a trainee in seasons 4 and 5 until passing his field exam.
175%%* TheLabRat[=/=]MisfitLabRat: At first.
176* LikesOlderWomen: If his apparent attractions to a Dolly Parton-lookalike gambling maven ("Revenge Is Best Served Cold") and a fading ex-showgirl legend ("Kiss Kiss, Bye Bye") are any indication...
177* MaybeMagicMaybeMundane: His grandmother had "the Sight" and the psychic who sensed his grandma tells him he has it too. One the one hand [[spoiler: he can't detect anything when he's in the "haunted" slaughterhouse with the killer]], on the other [[WildMassGuessing one could argue]] [[spoiler: the spirits are being really quiet so he can hear the killer's ringtone, which was caught on tape by the psychic before she was killed]].

190%%* CrazyPrepared
191* EnemyWithin: He possesses the same "serial killer" gene that Nate Haskell has.
192%%* ExtremeMeleeRevenge: Does this to Haskell in "In A Dark, Dark House."
193* FreudianExcuse: Played with. His father was apparently violent, and Raymond worries that he may become that way himself. He also has a gene that has been associated with violent behaviour. On the other hand, when faced with SerialKiller Nate Haskell, who has the same gene and his own abusive father, he testifies in open court against his attempt to use this card, and afterwards Haskell admits to him that he decided in his youth he'd blame it on those things if he were ever caught.
194* IAmNotMyFather: Due to his father's violent outbursts when Ray was growing up, he's now trying his best *not* to be like the man.
195* NotThatKindOfDoctor: Inverted, he ''is'' that kind of doctor.
196* TheProfessor: Is teaching college just before he takes the job as a [=CSI=].
197* PutOnABus: After killing Haskell, [[spoiler:he is discharged from CSI by IAB and sent back to the east coast with his former ex-wife. He's mentioned once in the Season 12 opener, but is completely dropped from the series afterwards, essentially completing his character arc. He's one of a handful of living characters that doesn't return for the series finale.]]

212->Played by: Creator/TedDanson
213* BewareTheNiceOnes: He's usually pretty easy to get along with and a decent boss. But threatening his [=CSIs=] or his family is a big mistake.
214%%* BunnyEarsLawyer: Almost as much, if not more, than Grissom.
215%%* {{Cloudcuckoolander}}: Sometimes, at least.
216%%* CoolOldGuy
217* DoNotCallMePaul: Can't stand his given name. See spoiler immediately below for why.
218* EmbarrassingFirstName: [[spoiler:''Diebenkorn Russell.'']]
219* FakingTheDead:
220** Does it with Catherine to escape the posse of hitmen after them.
221** Also in his premiere as he poses as a dead body for "''investigative purposes''".
222* {{Foil}}: He serves as one to Grissom: While Grissom distained the politics of the Supervisor position and made enemies by deliberately refusing to play, DB is much more political and willing to cooperate and play at appeasement. Grissom had an antagonistic relationship with Ecklie at the worst of times, but DB was ''hired'' by Ecklie and has a friendly rapport with him. Grissom tended to allow his team their rogue vendettas and CowboyCop moments as long as they achieved results and avoided crossing certain lines, while DB was hired specifically so he could [[ByTheBookCop reign in]] their wilder actions, and often calls for characters to calm down and rethink things logically.
223* IHaveYourWife: [[spoiler:[=McKeen=]'s people do this to him with]] his granddaughter in the Season 12 finale.
224* HappilyMarried: The only CSI to be this from the beginning, although things get strained later on when his granddaughter is kidnapped (There's Grissom and Sara, but that comes several seasons into the show).
225** [[spoiler: In ''CSI: Cyber'' he's divorced.]]
226* ShipperOnDeck: Seems to be one for Morgan and Greg. In one episode, he tells Morgan to go back to the crime scene and take "boyfriend Greg" with her.
227%%* SuspiciouslySimilarSubstitute: Not for Langston, but rather Grissom.
228* TeamDad: Picking up where Grissom left off, but in a different kind of way since D.B. is a literal father as well. He's especially this way towards Greg and Morgan, the two youngest [=CSIs=]. (Morgan's actual father, Ecklie, practically states this trope directly in ''CSI Down''.) He also acts as this on the fourth series, ''CSI: Cyber''.
229* TrueCompanions: He regards the CSI team as this. They're a little weirded out by it.

235* HeroicBSOD: She shows some signs of this following her [[spoiler: abduction and shooting]] in season 14.
236* MsFanservice: Wears more makeup than the other team members and her clip in the titles involves her running in a tight white T-shirt.
237* ParentalAbandonment: Ecklie left when she was 14. She uses the surname of her stepfather.
238* ShipTease: Several moments with Greg and, believe it or not, Hodges, whom she pretends to date to impress his mother.
239* VitriolicBestBuds:
240%%** A Type II with Greg and Sara is shaping up.
241** Absolutely has this with Hodges. They bicker frequently, but clearly care about each other. Morgan actually flat-out refers to him as her best friend, and even once agrees to pretend to date him in order to get his mother off his back. (And once her father begins dating his mother, well, both the bickering and the caring get more interesting.)

249* ConvenientComa: Ends Season 15 in this spot after being [[spoiler: brutally beaten and stabbed by the Gig Harbor Killer]]. With Elisabeth electing not to come back for the series finale movie, [[spoiler: it seems unlikely she's ever going to wake up. The GrandFinale confirms she died]].
250* DidntThinkThisThrough: She has a really bad habit of running off on her own to confront suspects when she's especially angry. It repeatedly gets her into trouble, ranging from being fired from the Seattle Police Department to being beaten into a coma.
251* DoNotCallMePaul: D.B. is the only person who'll call her 'Jules' and she doesn't like it. She prefers Finn. Interestingly, D.B.'s wife also calls her 'Jules', and she doesn't even react.

268* BrokenAce: He has promotion after promotion and enough commendations to fill the Marina Trench...and has an utterly screwed up life to go with it.
269* SuspiciouslySimilarSubstitute: He serves as a temporary replacement for Grissom both In-Universe and out, since Creator/WilliamPetersen needed time off to star in a play.
270* TakingTheBullet: [[spoiler:He dies doing this to save a hooker from Frank [=McCarthy=].]]

275->Played by: Creator/PaulaNewsome
276* AcademicAthlete: She attended university on a basketball scholarship and has her uniform framed in her office.
277* AmicableExes: While they don't speak often, Max's relationship with her ex husband is still strong enough that he was willing to get on a plane to Vegas the moment he heard her life was in danger from a serial killer
278* MamaBear: Max will not take it well if the safety of any of her [=CSIs=] are threatened. For example, after Folsom is hurt by what appeared to be an undetected second bomb at an explosion scene, she goes straight to the bomb squad officer who cleared the scene as supposedly safe to verbally eviscerate him.

After tricking him into thinking Josh slit his wrists and would bleed out if he didn't tell the truth, Josh finds scratch marks on the mans arm, matching the spot his mom clawed at before she died. This causes Josh to realize ''he'' killed her, and while what happens next is [[AmbiguousSituation intentionally vague]], the CSI's find the man's body dead in a dumpster, the kidnapping scene all but wiped clean, and Max and Chavez are forced to arrest him for the man's murder.]]

316->Played by: Creator/RobertDavidHall
317
318* BerserkButton:
319** He absolutely HATES rats, even if it only shows in one episode, aptly titled "Lab Rats."
320** More commonly seen is his tendency to get incredibly testy when he sees evidence of another medical examiner (or a paramedic, or a police officer) cutting corners or not following protocol. And don't even think about suggesting that he was less than thorough about doing his own job.
321* CoolOldGuy: He's the oldest of the cast, but is still known to rock out in autopsy on occasion and plays in a band himself.
322* TheCoroner: He's the Medical Examiner at the LVPD Crime Lab.
323* FamousAncestor: He is revealed to be distantly related to William "Buffalo Bill" Cody in the season 12 episode "Genetic Disorder."
324* GeniusCripple: He's a medical professional who just happens to be a double amputee with two prosthetic legs.
325* HandicappedBadass: He might need a cane to get around, but he can be a pretty mean fighter when he has to be.
326* HappilyMarried: Besides a few issues, he's one of two CSI employees, the other being D.B. Russell, to be this.
327* TheLabRat: Sort of, although he's a mortuary rat rather than a lab rat.
328* MrExposition: His autopsies often reveal further background on the murder victims.
329* NotThatKindOfDoctor: Played with. He obviously has a medical degree, but he doesn't practice medicine as his "patients" are dead. [[OnlyMostlyDead Well, but for that one time...]]
330* SympatheticAdulterer: Reveals in season 12 that he cheated once, essentially just to see if he had the guts to. It nearly ruined him and his wife, and they've been faithful ever since. It's really kind of adorable.
331* WhyDidItHaveToBeSnakes: Rats. On the one occasion when a rat ventures into the Morgue, he flat-out screams at it and tries to beat it with his cane.
332* WrittenInInfirmity[=/=]DisabledCharacterDisabledActor: Both Robert David Hall and Albert Robbins are double amputees.

351* NotThatKindOfDoctor: Just like Doc Robbins, she's an MD, but she doesn't practice medicine.
352* OneShotCharacter: Since she's the Day Shift Coroner, she usually isn't involved in the cases of the Night Shift. Her one appearance in "Genetic Disorder" came about because the VictimOfTheWeek was found in Doc Robbins' house and neither he nor David Phillips could autopsy said victim without inviting suspicions about inconvenient facts being covered up.

384->Played by: Creator/WallaceLangham
385
386* BornLucky: But only on a single day: April 7th. It's his lucky day. On this day, ''nothing'' has ever gone wrong for him, ever. In "Lab Rats," he takes advantage of it being his lucky day to help crack a case that even Grissom couldn't figure out.
387* BrilliantButLazy: Unlike most Lab Rat characters on the CSI shows, Hodges is quite content to remain indoors and hates going into the field.
388%%* BunnyEarsLawyer
389%%* DeadpanSnarker
390* DirtyCop: Averted. [[spoiler:The first episode of the revival uncovers evidence that, during his time at the lab, he faked results by the truckload, putting any conviction resulting from said fake lab results in jeopardy. Sara believes it to be a FrameUp, but the DA wants Hodges arrested anyway, and every one of the cases he was involved in is now under scrutiny. Sara, Gil, and the new CSI team manage to fully clear his name by the finale, thus saving the crime lab's integrity as well.]]
391* HiddenDepths: Among other things he's a big sci-fi geek, with an undying love for "Astro Quest" (fictional couterpart of ''Series/StarTrekTheOriginalSeries'').
392* LargeHam: Has his moments, but the "Astro Quest" episode (and the dream sequences that have Hodges as TheCaptain of the ShowWithinAShow) are pretty much a chance for Langham to unleash his inner Creator/WilliamShatner in a homage to "''The Gamesters Of Triskelion."''
393* MommasBoy: He is living with his mother when he first starts working at the lab. When she finally appears on-screen, we learn that she's a surprisingly attractive and classy lady, and far from the typical MyBelovedSmother that most mothers involved in this trope are.
394* TheNoseKnows: Has an incredibly accurate sense of smell. In "In Vino Veritas," he leans into a wine barrel that had held a corpse for a few days and deeply inhales, grossing out a co-worker. He explains that he can determine the source of the wine from the various ingredients he detects...over the smell of decomp. In "The Theory of Everything", Catherine has him get down on the floor of a victim's bedroom and smell the carpet for evidence, as he possesses the genetic makeup that lets him smell the presence of cyanide.
395* PetTheDog[=/=]EstablishingCharacterMoment: For the first couple of his seasons, he is portrayed as a through-and-through {{Jerkass}} ProfessionalButtKisser with no redeeming qualities whom all his co-workers hate. In Season 7, however, he gets a surprising amount of CharacterDevelopment in a scene where he has to break bad news to a victim's family, and he's portrayed as a sympathetic character ever since and even joins the main cast. He even gets a wife and by the end of season 1 of the revival, a child.

452
453* AllOfTheOtherReindeer: "A Bullet Runs Through It," where the other cops shun him at the dead officer's funeral.
454* BerserkButton: Bad fathers, likely because he wishes ''he'' [[MyGreatestFailure could've been a better one]].
455* BlindPeopleWearSunglasses: In the revival, he’s wearing them before revealing his eyes which were damaged in an attack. He’s not completely blind but can’t see very well.
456* TheBusCameBack: Comes back for the finale, and for a few appearances in the revival.
457%%* CoolOldGuy
458* DeadpanSnarker: On Vegas' staggeringly-high murder rate: "We're very competitive!"
459* DirtyCop : Originally a big subversion of this, stating how he refuses to be bought or get dirty, but drifts into that territory as of the end of season 11. [[spoiler:He covers for Ray when Ray kills Nate Haskell, and is reluctant to help catch a killer who was killing other killers.]]
460* EtTuBrute: In "A Bullet Runs Through It," he feels this way when one by one, all of the other officers walk away from him at the dead officer's funeral.
461* HandicappedBadass: He's in his 70s and half-blind come the revival series, but it opens with him kicking and killing the ass of a man sent to kill him.
462* HiddenDisdainReveal: Despite trying to help his daughter, even knowing she isn't actually his, every time she gets herself into trouble. [[spoiler:After a crime of hers gets her mother killed, he flatly tells her that she killed the only person who cared about her.]]
463%%zce* JerkWithAHeartOfGold: Eventually mellows out into this.
464* MrExposition: He's the man who gives both the team and the audience information on the latest victim of the week.
465* OutrankingYourJob: Spends a lot of time personally investigating crime scenes and chasing down suspects for a police captain.
466* ParentalIssues: He still loves his daughter despite knowing that she's not genetically his. Her...not so much, to the point that when Brass is shot he gives power of attorney to Grissom rather than to her. Another contributing factor is probably that she has been addicted to drugs and worked as a prostitute for a time, so it would be understandable for Brass to doubt her judgment in general.
467* PutOnABus: Takes a leave of absence for season 15 [[spoiler: after his daughter fakes her kidnapping with the help of a boyfriend, gets Brody involved and almost kills her, kills the boyfriend, and kills her mother (whom she didn't expect to come to Las Vegas) because she would have recognized the boyfriend. Amazingly Brass is helping her with her trial.]]

486->Played by: Creator/MarcVann
487
488* ADayInTheLimelight: The B-plot of one episode features Ecklie handling the investigation himself when the main characters are unavailable.
489* AmbitionIsEvil: The real reason he is such an ass to Grissom and the team was because he thinks that Grissom has the same ambitions he does. Once he realizes that Grissom and the team won't keep him from fulfilling his goals, he eases off considerably.
490** His behavior in the Season 14 episode "Consumed," though, suggests that running for sheriff may cause him to relapse.
491* BigBad: Arguably, of Season 5. He never does anything illegal, but his antagonistic actions drive the overarching plot of that season.
492* CharacterDevelopment: A fairly significant example of this. He's almost a completely different person now than he was in season 1. He makes a pretty seamless transition from {{Jerkass}} to JerkWithAHeartOfGold. After 13 seasons he's still a bit nasty at times, but he has the respect of the team and the department as a whole, and he has absolutely become a ReasonableAuthorityFigure. (He's aware of it, too: when he talks to Morgan about being offered the sheriff position, he admits that part of the reason he isn't sure about it is because he's afraid he'll revert to the manipulative asshole he used to be.)
493* DaChief: He starts out as the day shift supervisor, then becomes director of the lab, and is later promoted to undersheriff of the entire department. By mid-Season 13 he's the new sheriff. He almost doesn't take it at first, because he's worried that he'll revert to the {{Jerkass}} he used to be.
494* DiabolusExMachina: Supplies a rather nasty and completely out-of-nowhere one in [[spoiler:"Fracked"]]. (Though, granted, it's fairly clear that there's not much he can do.)
495* HeroicBSOD: This is debatably the cause of his considering leaving his job in Season 13. He doesn't show any signs of being tired of his job until the corruption of the department and his shooting.
496* JerkWithAHeartOfGold: He goes out of his way to make Grissom and the team look bad, particularly when investigating Gil and Sara's relationship after her kidnapping. However, he develops a "Heart of Gold" and becomes a ReasonableAuthorityFigure pretty nicely afterwards. His statement that he would've helped Grissom and Sara avoid any conflicts because of their relationship certainly sounded genuine, and he's been mostly a lot nicer to the team while still keeping his prickly attitude. Come the later seasons, he's been even better with Morgan around.
497* JerkassHasAPoint: Despite being rude, unpleasant, and power-hungry, he is accurate about Grissom's leadership in Season 5, especially in the way he handled Sara. By that point, she has become very unprofessional, culminating in Sara mouthing off to Catherine (at the time, a superior) in front of coworkers and to Ecklie himself. He was absolutely right to suspend her, something Grissom would not have done due to their relationship.
498* ObstructiveBureaucrat: He's extremely ambitious, and originally sees Grissom as competition. At different points, he would try and undermine the team's work.
499* ParentalAbandonment: He left when Morgan was 14.
500%%* RankUp: To Undersheriff and eventually Sheriff.
501* ReasonableAuthorityFigure: When Nick is BuriedAlive, Ecklie pulls some strings to gather the ransom his kidnapper demands, and relations between him and the night shift have mostly thawed since then. Ecklie comes into his own as Asst. Director, where his talent for juggling the top brass and news media have proven to be an asset to the team.
502** Once he's the new sheriff, he seems to have kept his reasonableness. The only time that he really pushes back against the team is when he's faced with having to give permission for his own daughter to be used as bait for a serial killer. A perfect example of his reasonable attitude is when Finn and Nick clash with a fire investigator at an arson scene. The investigator calls in Ecklie with "concerns" about their methods, and before passing any judgements, Ecklie hears Nick and Finn out and even takes his jacket off and helps them dig through a burnt-out building to prove their theory.
503%%* TheRival: To Grissom, who deplores Ecklie's careerism.
504* SmugSnake: Pre-"Grave Danger." He took utmost pleasure in seeing Grissom's team humiliated, and even worked to get Nick convicted of murder once purely out of spite.
505* TakingTheBullet: [[spoiler:For his daughter when he gets gunned down in ''Homecoming''.]] It's possible that they had been aiming intentionally for him, but given that he [[spoiler: shot [=McKeen=]'s son]], it seems likely that Morgan was the target.

586->Played by: Creator/MelindaClarke
587
588* BrainsAndBondage: A licensed therapist...who also happens to run an S&M club.
589* TheBusCameBack: Really never appears after William Petersen/Grissom stopped starring in the show, only appearing once for a case in Season 11. She returns as [[spoiler:a suspect yet again in one of the most massive cases to hit the show in ''C.S.I.'''s series finale.]]
590* CollateralAngst: Not Heather herself, but in the GrandFinale [[spoiler: her toddler granddaughter is offhandedly revealed to have been killed in a car accident, which serves little purpose other than driving Heather across the DespairEventHorizon so she can be a murder suspect. She pulls the plug on her practice after her granddaughter dies, which helps set up the plot of the GrandFinale]].
591* CreepyGood: For a creepy dominatrix lady she has a surprisingly good heart.
592* DarkIsNotEvil: Though she seems scary at first and is into some pretty dark stuff, she is definitely a good guy.
593%%* {{Dominatrix}}: Her chosen profession.
594* DrivenToSuicide: Sort of. [[spoiler:In one episode, she hires a guy to kill her because she lost custody of her granddaughter.]] She lives, though.
595* DropInCharacter: Cases have a weird way of tracing back to her.
596%%* EthicalSlut: As befits her profession as a {{Dominatrix}}.
597* LovableAlphaBitch: Emphasis on the "alpha" part as she's a {{Dominatrix}} by trade.
598* TheMaidenNameDebate: Strangely enough, she apparently took her husband's name.
599* MamaBear: Do ''not'' mess with her daughter. [[spoiler:She WILL perform her S&M routine on you to make it hurt before she kills you.]]
600* OfCorsetsSexy: Wearing one when we first meet her.
601* TheVamp: Used for good! In her third appearance, she sleeps with [[spoiler:Leon Sneller, the guy who killed her daughter]] to get evidence from him to give the team.
602* WhipOfDominance: She is a professional {{Dominatrix}} who runs an S&M club and in "Pirates of the Third Reich" she's shown to be quite skilled with the whip when she apparently managed to capture her daughter's murderer using [[WeaponsOfTheirTrade the whip she uses for her work]] and by the time Grissom finds her she has him tied to the grill of a car and is planning to whip him to death. Grissom even convinces her to stop by using to safeword, to further drive home the S&M theming.

605[[folder:Sam Braun]]
606->Played by: Creator/ScottWilson
607
608* BigScrewedUpFamily: One son is a murderer, the other a heartless casino shark, and Sam himself might possibly be ''both''. [[WhiteSheep At least there's Catherine]].
609* CainAndAbel: One of his sons kills the other out of jealousy.
610* LukeIAmYourFather: We're informed he was an ex-boyfriend of Catherine's mother in prior episodes, so there's some {{foreshadowing}}.
611%%*CorruptCorporateExecutive:
612* DirtyOldMan: Definitely seems to prefer his women a full generation younger than him.
613%%* DisappearedDad
614%%* TheDon: Gives off this impression, but nothing's ever proven beyond this.
615* DropInCharacter: It's apparently a small Vegas after all, because like Heather, his name comes up in a frankly absurd amount of cases. The difference, of course, being that while Heather usually takes the role of key witness, Sam being who he is is often the prime suspect.
616* KarmaHoudini[=/=]NotProven: He is a suspect in a murder from decades ago, and Catherine wholeheartedly believes it was him, but there is another suspect to whom all the evidence seems to point, and Sam is never charged.
617* KickTheDog: Organizing the bank robbery that gets [[spoiler:Detective Lockwood]] killed. Kept from being a full-on MoralEventHorizon-crossing by the fact that Sam doesn't ''intend'' anyone to die and the AxCrazy head robber foes off the rails, but the fact that he is willing to put innocent people [[spoiler:and lovable supporting cast members]] in a life-threatening situation purely for his own benefit is a pretty huge dick move.
618* MoralityPet: Catherine. He also expresses genuine affection for Catherine's mother and Lindsay, but is not of seen interacting with them on-screen.
619* PetTheDog: Hates himself for favoring his older son, leading to the jealous younger one killing him.
620* RedHerring: No matter how good his motive or opportunity may be, he is ''always'' this.
621%%* EvilOldFolks:
622* VigilanteExecution: [[spoiler:...by the domestic partner of a man Braun had financially ruined]].

625!! Criminals
626[[folder:Paul Millander/The Bathtub Killer]]
627->Played by: Creator/MattOToole
628
629* BigBad: Of the pilot and a good chunk of the first two seasons.
630* ChekhovsGun: The rubber hands he makes in his shop, the hand impression his father had made for him, and the ID his son makes for Grissom all turn out to be crucial to the case.
631* TheChessmaster: Far smarter than the entire team ''put together''.
632* DarkIsEvil: Before going on the run, he is the owner of a shop that sells ''seriously'' grisly Halloween props.
633* EvilCounterpart: To Grissom; bonus points for being the first major ''C.S.I.'' nemesis to ever appear in the franchise.
634* FreudianExcuse: He (or rather, "she" at the time) watched as his father was murdered and the death made to look like a suicide in his own home, and then his testimony was thrown out at the trial and the killers went free.
635%%* HangingJudge: In his SecretIdentity.
636* TheHeavy: For much of seasons 1 and 2.
637* KarmaHoudini: Of a sort; he commits suicide, in the same way he killed his victims no less, to deny Grissom the satisfaction of sending him to jail.
638* MommyIssues: His mother ostracized him after his operation. [[SelfMadeOrphan He repays her with a knife to the gut]].
639* ThatOneCase: For Grissom. One of Millander's victims is the primary victim of the pilot episode.
640* PetTheDog: Revealed posthumously; he honestly loved his adopted son.
641* SecretIdentity: As a judge, complete with a family who know nothing of his murderous ways.
642* SerialKiller: The series' first, and the setter of the standard for season-long arcs focusing on serial killers for both this and the other ''C.S.I.'' shows.
643* SeriesContinuityError: A major plot point in his last episode is that he and his father have the same name... except that the elder Millander's name was given as "John" in a prior episode.

646[[folder:The Miniature Killer (contains spoilers)]]
647->Played By: [[spoiler:Creator/JessieCollins]]
648* ArchEnemy: [[spoiler:Natalie Davis]] quickly becomes this to Gil Grissom, [[spoiler:especially after she kidnaps Sara and leaves her for dead.]]
649* AxCrazy: Key word: [[spoiler:Bleach. Say this to her or make any indication of the thing and you're dead.]]
650%%* BigBad: Of Season 7 and the first episode of Season 8.
651* TheBusCameBack: [[spoiler:Natalie Davis returns in one of Peterson's last episodes for a hearing about whether or not to transfer her to prison, which they do. She has worked over her bleach problem by this time.]]
652* EideticMemory: Can recall the minutest details of a location after a short glance, which helps in making the miniatures.
653* TheHeavy: Has this on Grissom long after being put in prison, only matched by Millander and later Nate Haskell for Ray Langston.
654* SiblingMurder: As a child, [[spoiler:Natalie murdered her sister Chloe by pushing her out of a treehouse, because she was jealous of the attention her sister was receiving after her mother's death. This is also what causes her thing regarding bleach, as her father used it to clean her sister's blood off of the concrete.]]
655* ThatOneCase: One of the most unique villains in the history of the ''C.S.I.'' franchise, their entire M.O. with creating miniatures of future murder scenes then executing the scene to exacting standards became a hot topic both in the show and in real life for the 2006-2007 TV season.
656* TheUnfavorite: Was this as a kid, and it's implied [[spoiler:Natalie's first kill was her older sister, in an attempt to finally get attention]].
657* VillainousBreakdown: [[spoiler:When she's finally arrested, Grissom's attempt to force Sara's location out of her drops her into a catatonic state that requires her to be institutionalized.]]

659
660[[folder:Nate Haskell/The Dick & Jane Killer]]
661->Played by: Creator/BillIrwin
662* AbusiveParent: His father was a drunk who would beat him and his mother.
663* AllGirlsWantBadBoys: This monster has a "bride" fanclub.
664%%* ArchEnemy: To Raymond Langston.
665* AssholeVictim: After all he's done, it's hard to feel sorry for him after [[spoiler:Raymond Langston kills him.]]
666* AttentionWhore: After being caught, he pleads not guilty, but later confesses when his defense claims that his crimes could only have been committed by multiple people working together. He is also the only murderer to accept the opportunity to speak to a class during a lecture.
667* AxCrazy: As Brass puts it, "He's like the Joker from Batman, except without the laughs."
668* BigBad: Of Langston's intro episode halfway through Season 9 (this was also Grissom's final regular story arc as a character until the series finale), and of Season 11. [[spoiler: His death is what ends Langston's character arc and his time at C.S.I.; Fishburne was asked to leave at that point and was replaced by Ted Danson.]]
669* BlatantLies: While torturing his victims, he offers them a chance to survive. They never do.
670* ChickMagnet: While in prison he gets proposed to a few times.
671* ContrastingSequelAntagonist: To the earlier ArcVillain. The Miniature Killer was an isolated individual who was a forensic challenge to the [=CSIs=] to track down, while Nate is a psychological foe who is able to manipulate others into helping with his plans even behind bars. They also contrast physically: [[spoiler:Natalie is a young woman who looks and acts like a stiff breeze would blow her over, while Nate is a middle-aged man who can pose a physical threat.]]
672* TheCorrupter: While other aspects of his M.O. change, he consistently takes pleasure in convincing others to become killers like him, whether it's his accomplices in the original Dick and Jane killings, or the [[spoiler: groupies who bust him out of custody and then murder each other]] or, in the end, [[spoiler: Ray Langston]].
673* DarkAndTroubledPast: Was abused by his father and listened to him kill his mother when he was ''eight.''
674* EnemyMine: Helps the CSI team find Dr. Jekyll. He uses the whole thing to ultimately set up his escape.
675%%* FourEyesZeroSoul
676* FreudianExcuse: His dad beat his mom to death and made him listen to her screams.
677* TheHeavy: This guy's specter hangs over the C.S.I.s from his first appearance to [[spoiler: just past his death when his saga results in Langston being forced out and Catherine and Nick getting demoted back to their original positions from when Grissom dealt with Haskell; this leads to Catherine's own exit from the lab later.]]
678* IHaveYouNowMyPretty: Kidnaps Langston's ex-wife and rapes her, among other things.
679* InTheBack: Stabs Langston in the kidney area in the 10th season finale.
680* KillAndReplace: "Nate Haskell" turns out to have been the name of his first victim, a traveling salesman whose identity he stole. His real name is Warner Thorpe.
681* {{Sadist}}: Brass compares him to the ''Joker!'' Need we say any more?
682* SevenDeadlySins:
683** Pride: See AttentionWhore above.
684** Lust: Takes sadistic pleasure in corrupting others and making them suffer.
685* TortureTechnician: And how! At one point he kidnaps Langston's ex wife and puts her in a torture device that would not be out of place in ''Franchise/{{Hellraiser}}'' films.
686* YouHaveOutlivedYourUsefulness: Kills his final MonsterFangirl, after most of the others kill one another.

689[[folder:Dr. Jekyll/ Chef Charlie Dimasa]]
690->Played by: Creator/MattRoss
691* ArchEnemy: To Ray in Season 10; he loses this position back to Nate Haskell [[spoiler:after he's killed.]]
692%%* BigBad: Of Season 10.
693* TheHeavy: Ray is really troubled by this suspect, especially when they meet in a hospital and Jekyll steals Ray's ID card, which he mails back along with prosciutto that has a Jane Doe number of an earlier botched victim on it; [[NiceJobFixingItVillain this is how they identify him when they match DNA he left]] to [[spoiler:his father's septic appendix]], which is found in his second victim (and the first one he actually killed) earlier in the season.
694* MeatgrinderSurgery: Subverted; he takes great care when performing his surgeries/murders, which does not help the case at all.
695* NonIndicativeName: He is named after [[Literature/TheStrangeCaseOfDrJekyllAndMrHyde Dr. Henry Jekyll]] even though the killer does not have an [[JekyllAndHyde evil split personality]] and Jekyll is supposed to be the good one. Furthermore, while most versions of Jekyll are medicinal doctors, none of them are surgeons who performed gruesome operations on innocent people and neither did Hyde.
696* SecretIdentity: [[spoiler:Dr. Jekyll turns out to not be a doctor at all, but a cook in a luxurious Italian restaurant who had to drop out of medical school to assist his father. He does well as a chef, but does not take the whole thing well at all, hence his literal butchering surgery on the season's victims.]]
697* ThatOneCase: Jekyll's odd surgeries (starting with someone who was already dead, but moving on to actual murder thru surgery after the C.S.I. trilogy) stump Langston and Dr. Robbins throughout the show's 10th anniversary, with Langston taking his work home. They [[DealWithTheDevil eventually have]] to [[EnemyMine enlist Nate Haskell]], the BigBad of Ray's introductory episodes, to finally bullseye Jekyll, but this move [[NiceJobBreakingItHero leads to the Season 11 plotline]] and the events that end in Langston and Catherine's departures from the crime lab.
698* VillainousBreakdown: [[spoiler:When Langston and Stokes find him, he finally turns on the Mr. Hyde persona for the first and only time by grabbing a shotgun, blowing the head off a cop, shooting up his restaurant and trapping everyone there.]]

703* ArchEnemy: Temporarily becomes one to Nick via communications and bombs until he is killed.
704* AssholeVictim: Jason has already killed a bomb technician friend of the team's and injured Vartaan by the time he goes on a short-lived shooting rampage against a police roadblock with Nick and Brass.
