!Main Characters
[[folder:Special Agent in Charge Leroy Jethro Gibbs]]
->'''Played By''': Creator/MarkHarmon
[[quoteright:325:http://static.tvtropes.org/pmwiki/pub/images/LeroyJethroGibbsNCIS_5376.png]]
->'''Tony:''' ''What have you heard? That suspects would rather confess than be interrogated by him? That his steely gaze can cool a room by five degrees? That he can only be killed by a silver bullet, like a werewolf? Well, it's all true, except the silver bullet part. Might give him indigestion or heartburn, but I don't think it'd kill him. Any other questions?''

Not to be confused with [[LudicrousGibs Ludicrous Gibbs]], though he does pull some pretty crazy stunts to get the bad guys. The team leader, a former Marine sniper, and interrogator extraordinaire.

* ActionDad
* AffectionateGestureToTheHead: Only Gibbs could turn his repeated [[DopeSlap dope slaps]] to [=DiNozzo=] into this.
* AlwaysGetsHisMan: Highlighted in ''Mind Games'': The serial killer featured in that episode was the boogeyman of D.C. when he was active, evading metro cops and terrorizing the female populace. When explaining the case to [=McGee=], Tony and Paula Cassidy finished by saying "But he made one crucial mistake: He killed a Petty Officer."
* AmnesiaDanger: In "Hiatus", a bomb blast knocks Gibbs back to his Marine days. He has critical information that he doesn't remember. Luckily, [[EasyAmnesia remembrance]] is just a DopeSlap away.
* AtonementDetective
* {{Badass}}: There's a good reason why he has MemeticBadass status in-universe.
** BadassGrandpa
* BadBoss: Gibbs leans toward this when he's really angry or upset, as his already-considerable impatience skyrockets, his tolerance for the team's personality quirks goes right out the window, and he gets a lot snippier and DrillSergeantNasty-ish.
* BerserkButton: Do not insult, desecrate or harm the US Marines or anyone associated with them to the Nth degree. Do not hurt any member of his team or anyone else he cares about. And seven ''thousand'' times never hurt Abby (though Abby usually has the situation well in hand).
** People who do harm to kids, especially their own.
** Messing with his coffee, although his reaction to this is fairly minor in comparison to the others.
* [[BornInTheWrongCentury Born In The Wrong Decade]]: Fairly consistent throughout the series. Example: he tried to get a USB drive to work by biting it.
** He also refers to computer chips and the like with terms such as "doo-da" and "deweywhacker."
** It's hard to keep track of how many cell phones he's destroyed during the run of the series, either because they malfunctioned or just generally annoyed him. One even wound up in a jar of paint thinner. His agents now keep plenty of spares in their desks, ready to hand to him at a moment's notice. When the stash ran out, the tech department went crazy.
** When a Roomba vacuum cleaner was about to suck up some of the evidence from a crime scene, he didn't even bother picking it up or trying to turn it off. ''He stomped it to pieces.''
* BrokenBird: [[spoiler:He has never fully recovered from the murder of his wife and child. Three ex-wives and dozens of girlfriends that didn't go anywhere are what remains of his love life.]]
* BunnyEarsLawyer: In a more dramatic than comedic fashion. He has some serious quirks that if not for the fact he gets the bad guys and never gives anything but his best, he wouldn't be employed. For instance, in early seasons, he once interrogated some people by talking with them ''in autopsy as Ducky was working on their alleged victim''. It's acknowledged that except for his impatience for dealing with politics, he could be the ''Director''.
* ByronicHero
* CartwrightCurse: With his first wife and [[spoiler: Jenny Shepard.]]
* CatchPhrase: "Ya think?", "What's the point, [=McGee=]?", "Yeah, Gibbs" (default phone answer), and "That's a good question, [Character]. Why don't you find me an answer?", "Grab your gear."
* ChestOfMedals: Subverted, he's {{Badass}} enough to have earned numerous medals and citations to be this if he wanted but he doesn't care for medals, Tony apparently keeps track of his accomplishments. He even gave away his Silver Star which is the second highest honour that a US serviceman can get for valour in the face of the enemy.
* ColdSniper: Marine sniper previous to his current employment.
* CoolOldGuy
* CowboyCop: But he always gets away with it. He's ''Gibbs''. And "he only uses his powers for good".
* CrazyPrepared: As shown in the blackout, he has a kit with three polaroid cameras, Band-Aids, food, and clean socks.
* CrusadingWidower: He didn't rest until he hunted down and [[spoiler: killed the man who slaughtered his first wife and their eight-year-old daughter]]. Actually, he didn't rest after that either.
* DeadpanSnarker: More than half of what he says is pure snark.
* DeathGlare: Has one that is very effective in breaking a suspect or stop Tony when he was being an idiot. This is his default look when his Berserk Buttons are pressed.
* {{Determinator}}: Few things will stop him from getting Justice for those harmed. He will even break some laws if need be.
* DopeSlap: Aka the "Gibbs Slap" done to all of his agents, but to Tony the most. He's even self-inflicted when he knew he was doing something he'd slap any of his agents for.
* DrivesLikeCrazy: Kate at one point describes his driving as "Apparently Gibbs is trying to kill us." He's also the only one on the team unfazed by the motoring antics of Ziva, another crazy driver.
* {{Embarrassing First Name}}: Though it's never stated that he's embarrassed by it, [[DoNotCallMePaul no one except residents of his hometown or his ex-wives call him 'Leroy']].
* FairCop
* AFatherToHisMen: Ziva directly calls him "the closest thing she has to a father". (Note that her father is very much alive.)[[spoiler:He ''was'' at the time]]
** Later, he explicitly refers to [[TheTeam his team]] as his "kids."
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Choleric
* FriendToAllChildren: Probably has something to do with Kelly. If there's a child involved, he will take the case very [[ItsPersonal seriously.]]
* GuileHero: Just as guile as a MagnificentBastard is magnificent.
* GutFeeling: It's legendary. Some fans consider his gut an extra character. His gut has MemeticBadass status ''in-universe.''
* TheHero
* HasAType: See below.
* HeroesWantRedHeads: His four past wives, and Jenny Shepard (who the two had a past relationship) are all redheads. He's dating a redhead in the series.
** When Tony learns about Gibbs flirting with a suspect, his immediate response is "Is she a redhead?" She is.
* HeterosexualLifePartners: With Ducky.
* HonoraryUncle: To Fornell's daughter by their mutual ex-wife. Also with Mike Franks' half-arab granddaughter (who is also his goddaughter).
* HopelessWithTech
* ItsPersonal: He has a tendency to do this. As said, anything involving children (or otherwise reminding him of Shannon and Kelly) automatically becomes this. Hurting anyone from his team also pushes him to this point. But every criminal that is disgusting enough to him can trigger this.
* JerkWithAHeartOfGold
* KnightInShiningArmor: To the women in his team, especially Abby.
* LastNameBasis
* LaymansTerms: Does this at least once an episode, mostly to Abby, Ducky and [=McGee=].
* TheLeader: Of the Major Response Team.
* MagneticHero
* MemeticBadass: In-universe.
* MilitaryMaverick
* MustHaveCaffeine: In the form of coffee.
* NoodleIncident: We still don't know the identity (or much of anything) about one of his ex-wives...
* [[OldSoldier Old Marine]]
* PapaWolf: Do ''not'' endanger his people. Just don't. ''Epecially'' Abby.
-->'''Abby''':(telling Gibbs why she didn't tell him about an ex she got a restraining order on) "I wanted him restrained, Gibbs, not beaten to a bloody pulp."
** He extends these tendencies in the episode "Requiem" to his deceased daughter's now grown friend Maddie. Twice he's asked if he's her father. He shrugs it off. But ultimately, it's evident he views her in the same light as the rest of his team...as family.
* PerpSweating: A master of interrogation.
** Especially when applying his DeathGlare.
** Don't make Gibbs slap the table. [[YouWouldntLikeMeWhenImAngry You wouldn't like Gibbs when he slaps the table.]]
* PhraseCatcher: "On it, Boss."
* RatedMForManly
* RightBehindMe: Tends to evoke this reaction from his agents.
* RuleNumberOne: "Never let suspects stay together," or maybe it's "Never screw over your partner." There's a lot more "Gibbs Rules", but it's hard to keep track, since he tends to make up NewRulesAsThePlotDemands.
** "Never let suspects stay together" is not actually a Gibbs rule, or at least not exclusive to Gibbs. It's generally considered by investigators to be rule number one when interrogating suspects. Gibbs still includes it in his rules.
** The ones shown tend to be consistent: Never let suspects stay together, Never go anywhere without a knife, Never involve lawyers, Never get personally involved, Never screw over your partner. Rule 44 was sent to Mike Franks to get him away from his house before he was attacked. We only see 15 out of 51 rules for the most part.
** Tony mentions that any situation that requires Gibbs to invoke any rule in the 40s is serious business.
* SexyMentor
* SemperFi: And Gibbs always remembers it.
* SilverFox
* TheStrategist
* SugarAndIcePersonality
* SympatheticMurderBackstory: He killed the killer of his first wife and daughter.
* TeamDad: To his agents, but especially to Abby.
* TechnologicallyBlindElders: It's a RunningGag that he doesn't know how the digital gadgets work.
* TenMinuteRetirement: Took a little longer than most but he had one.
* UltimateJobSecurity: It may change with Vance, but it seems this man can never get canned.
** And, now Vance and Gibbs are friends of a sort, ''and'' Vance knows that Gibbs has the ''unaltered'' copy of Vance's personnel file - even if he's never opened it. ''Yet''. Nope, Gibbs has yet again armor-plated his job security in adamantium.
** When Gibbs "retired" at the end of season 3, it later was revealed that Director Shepard had "neglected" to file his retirement. His job security is so great he can't quit even if he wants to!
** It has been implied on occasion that before Vance, and possibly even during Vance's tenure, Gibbs would be Director if he ever decided he wanted the job; the sheer havoc he could cause if denied means only a fool would try to stop him.
*** It has been implied more than once that Gibbs knows how to deal with politics and how to act as a proper Director. He just doesn't care to do so. The one time Gibbs acted as Director while Jenny was away we found out he doesn't the patience for the politics.
--->'''Director Shepard''': Jethro's a great field agent, a great team leader, and he deals more efficiently with difficult politicians than I do.\\
'''Captain Todd Gelfand''': Then why isn't he the...\\
'''Director Shepard''': He shoots them.
* UltimateShowdownOfUltimateDestiny: [[invoked]] The team has had discussions pitting Gibbs vs. the likes of TheTerminator, Franchise/{{Godzilla}}, Mothra, and [[MirrorMatch himself]]. They tend to [[MemeticBadass give the edge to Gibbs.]]
* WorkingWithTheEx
[[/folder]]

[[folder:Senior Special Agent Anthony "Tony" [=DiNozzo=] Jr.]]
->'''Played By''': Michael Weatherly
[[quoteright:325:http://static.tvtropes.org/pmwiki/pub/images/TonyDinozzoNCIS_6560.png]]
->'''Ziva:''' ''Tony, your dying words will be 'I've seen this film'.''

* AccidentalMisnaming: Of course, there's the [=McNicknames=], but Tony gets his own share of this from Fornell, who pronounces his name [=DiNotso=] (he says the double z's like 'pizza') and occasionally [=McGee=] calls him [=DiNosey=].
* BecomingTheMask: In season four when he went undercover.
* BelligerentSexualTension: With Ziva.
* BerserkButton:
** Don't '''ever''' betray NCIS or the USA in general (like [[spoiler:Agent Lee]]) or [[HypocriticalHeartwarming make fun of people he makes fun of but you don't know]] (like Det. [=McCadden=]).
** Oh... and don't try to kill him and then think you can work with him.
** And for the love of all things military, leave Ziva alone.
* BewareTheSillyOnes: Do ''not'' let the Cassanova-like personality with all the jokes and snark fool you. He is a trained interrogator and can break anyone given the right leverage.
* BunnyEarsLawyer: Very often Gibbs catches him apparently slacking off, only to then reveal all the investigation and work he's been doing.
* ButtMonkey: In the early seasons, this was his position for the most part. In the pilot, he was thrown out of a car onto a highway and in the second he was thrown out a plane, he had a parachute in this case.
* TheCasanova: Especially in early seasons, he was seen as wooing a lot of women. After his time with Jeanne, it slowly stopped.
* CatchPhrase: "On it, boss."
* ClearMyName: Twice. First [[spoiler:the lab assistant Chip hated him for getting him fired in the past]] and sought out a complicated, nearly forensic-proof case. Second [[spoiler:Jeanne Benoit]] claimed to have seen him [[spoiler:kill her father, the arms dealer René Benoit ("La Grenouille")]].
* CrouchingMoronHiddenBadass
* DeadpanSnarker: Almost every sentence contains some snark.
* DistressedDude: Generally, Tony is the resident dude in distress, but he usually manages to get himself out of his situations by himself.
* ExasperatedPerp: His preferred method of interrogation. Most prominent when he doesn't ask questions, but just sits there, chewing on his tie and playing ''VideoGame/{{Tetris}}'' on his phone.
** He once inverted the trope, pulling it off while ''he'' was the one being interrogated. [[SugarWiki/MomentOfAwesome By the director of Mossad,]] who he successfully aggravated into admitting that he had [[spoiler: sent the agent Tony had killed to spy on a meeting of several law enforcement agencies, which were discussing an operation regarding Israel.]]
* FairCop
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Sanguine
* FreudianExcuse: One that's something of a TearJerker: It turns out the reason Tony's such a movie buff is because his mother took him to movie theaters a lot when he was a kid before her death; they were even watching a movie when she passed away in the hospital. Ziva notes the {{irony}} that this is the first time Tony's ever mentioned his mother to her.
* GenreSavvy: He's a big movie buff, and will very often find a way to compare the current case to a movie he's seen.
** Occasionally, however, he turns out to be WrongGenreSavvy.
* HandsomeLech: From "Hung Out to Dry":
-->'''KATE''': "Your mind, [=DiNozzo=], runs the gamut from 'X' to triple 'X'."
* HeyYou: Calling [=McGee=] Probie or one of many [=McNicknames=].
* JerkJock: He did graduate with a major in Phys Ed you know...
* JerkWithAHeartOfGold: If you dig deep enough, you may find it, somewhere.
* LadykillerInLove: With Jeanne Benoit; he was undercover at the time, so it wasn't supposed to happen.
** [[spoiler:And now, with Ziva, apparently.]]
* TheLancer
* [[LastMinuteHookup Last Minute Kiss]]: [[spoiler:With Ziva, ending 8 seasons of UST in her final episode.]]
* LockedInAFreezer: With Ziva in "Boxed In".
* MockMillionaire
* TheMovieBuff
* MrFanservice
* MyFriendsAndZoidberg: Is on the receiving end of this ''twice'' in the episode "Last Man Standing."
* NumberTwo: Abby at one point claims he "becomes Gibbs" when Gibbs is not around.
* ObfuscatingStupidity: In the rare times when he's totally serious, it's almost scary.
** Watch his interrogation room time in "Iced." He may have majored in Phys Ed, but he paid attention in his core classes.
* PersonaNonGrata: After the events of "The Admiral's Daughter," he can never go back to Marseilles again (Despite the fact that the mess in question wasn't his fault).
* PluckyComicRelief: In the first few seasons.
* PornStash: We've never seen it, but it must require a C-5 Galaxy to carry.
** However, in "Bikini Wax," he reveals that he has a subscription to "GSM" ("Get Some Magazine"), and brings in one of the issues from his collection because the victim had a photo shoot in it.
* ReplacementGoldfish: Owns a literal one. Her name's Kate. (See below.)
* ReferenceOverdosed: His movie references turn this show into this all on his own.
* SharpDressedMan: Several episodes reveal that his wardrobe is a who's-who of expensive name brands. His grousing during the shower scene in "SWAK" is one of the best examples:
--> '''Tony''': This very instant, someone is incinerating my Ermenegildo Zegna suit, my Armani tie, my Dolce & Gabbana shirt, and my Gucci shoes!
* SensitiveGuyAndManlyMan: Manly Man to [=McGee=]'s Sensitive Guy.
%%* SmallNameBigEgo
* SpannerInTheWorks: Tony is often so unpredictable that he can screw over the best laid plans of the villains by simply being his annoying self. This is also his preferred method of interrogation, thinking so far out of the loop that rehearsed defenses are useless, and being so annoying or weird that the suspect is unable to think clearly. This methodology also proves useful when he is being interrogated by the FBI or the Director of Mossad. He even called himself one in the season 7 opener:
--> '''Tony''': I'm the wildcard. I'm the guy that looks at the reality in front of him and refuses to accept it.
* TallDarkAndSnarky
* TenMinuteRetirement: Between seasons 10 and 11, to get the case against Gibbs dismissed.
* TookALevelInBadass: ''Multiple'' levels between seasons three and four, then smaller yet still noticeable levels between seasons five and six, then multiple levels again between seasons six and seven.
* UnresolvedSexualTension: A little with Kate, but to a much greater degree with Ziva.
** TheyDo: [[spoiler:With Ziva.]]
* UrbanLegendLoveLife: Starting in season five. He acknowledges in Season Six that he's going through a dry spell since falling in love while undercover. He just doesn't want anyone to know.
* VitriolicBestBuds: Type 2 with [=McGee=]. They act almost like [[SiblingRivalry brothers]].
** Tony is also very close to Gibbs, but you wouldn't say so from their [[JerkWithAHeartOfGold normal]] [[DopeSlap interactions]]. It's the same story with Kate (which appears at first like a type 1), and with Ziva.
* WellDoneSonGuy:
** Mostly in the early seasons, with Gibbs.
** Also clearly present with his biological father. They're improving.

[[folder:Field Special Agent Caitlin "Kate" Todd]]
->'''Played By''': Sasha Alexander
[[quoteright:208:http://static.tvtropes.org/pmwiki/pub/images/Kate_Todd_1145.jpg]]
->''"Hack into the servers. I can't believe I just said that. I would have never suggested that before I started working here."''

* ActionGirl
* AloofDarkHairedGirl: Can be cold, especially towards Tony.
* BoomHeadshot
* BrainyBrunette
* BlatantLies[=/=]{{Hypocrite}}: She and her friends conducted themselves with dignity on spring break, she says. College fraternities are bizarre, she says. Tony's MaleGaze habit is sick and wrong, she says. But then they walk in on a photo shoot for the [[MrFanservice US men's water polo team]] and she gets DistractedByTheSexy about as easily as Tony ever did.
* CatholicSchoolGirlsRule: Tony imagines her dressed as such.
** Also an {{homage}} as she was dressed as [[Film/KillBill Gogo]].
* DroppedABridgeOnHer
* DeadpanSnarker
* DiesWideOpen
* EmotionlessGirl: You can feel a breath of cold air when she talks, especially to Tony.
* FairCop
* FamousLastWords: [[spoiler:''(after Tony told her that she did well and Gibbs said he was right)'' [[KilledMidSentence "Wow, I thought I'd die before I ever heard..."]]]]
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Melancholic
* FormerTeenRebel: [=DiNozzo=] finds out that when she was a university student, she once engaged in (and won) a wet T-shirt contest. This also falls under BlatantLies / {{Hypocrite}} since she lied to Tony about what she did during Spring Break.
* HorribleJudgeOfCharacter: She thinks she is a good one but has helped more than one murderous psychopath because they look sympathetic. [[spoiler:One nearly kills her, another actually does.]]
* ImGoingToHellForThis: In the episode where the victim and attacker were on the same "dating" site
--->'''Abby:''' Care to guess what their fetish was, Kate?\\
'''Kate:''' Oh, no. I'm going to hell just listening to all this.
* InformedAbility:
** Ari comments on her freakish observation skills - but the next episode Gibbs corrects her recreation of room. And on a different occasion this former Secret Service agent couldn't kill Ari because his eyes looked kind...
** Not to mention the time she was so sure Gibbs hadn't seen a bomb she told him he needed glasses. It was a delayed-explosive.
* LadyOfWar
* MoodWhiplash: Causes two cases back to back in the Season 2 finale when she [[spoiler: takes a bullet for Gibbs]] only to reveal [[spoiler: she was wearing a bullet-proof vest]] only to then [[spoiler: immediately get shot in the head]].
* MsFanservice: A major subplot in "Conspiracy Theory" revolved around Tony finding a (real) picture of her in a wet T-shirt contest and using it as blackmail material.
* OnlySaneWoman: She felt like this at times with Gibbs and Tony at the beginning.
* RavenHairIvorySkin
* SugarAndIcePersonality
* TomboyAndGirlyGirl: The Tomboy to Abby's Girly Girl.
* TonightSomeoneDies
* TwoFirstNames: Applies to her actress too.

[[folder:Abigail "Abby" Sciuto]]
->'''Played By''': Pauley Perrette
[[quoteright:325:http://static.tvtropes.org/pmwiki/pub/images/AbbySciutoNCIS_8845.png]]
->'''Tony:''' ''Abby Sciuto, resident NCIS forensic scientist, heart and soul. [[ARiddleWrappedInAMysteryInsideAnEnigma A paradox wrapped in an oxymoron, smothered in contradictions in terms.]] Sleeps in a coffin. Really, the happiest goth you'll ever meet.''

* AllWomenArePrudes: Subverted. She has no problem with sex, just certain expressions of it (like Palmer's foot/shoe fetish AND how carefully he takes note of his coworker's footwear...)
* AwesomenessByAnalysis
* BadassAdorable: Once, she was AloneWithThePsycho, [[spoiler:who was her current assistant,]] and he tried to kill her. The team figured it out, and came running, [[RedundantRescue only to find that she had kicked his ass, hog tied him, and gagged him.]] She wasn't even winded. There's also the time she [[spoiler: was taken by a hitman hired to kill her to prevent her from testifying.]] By the time Gibbs and company arrive, she's using a taser on him.
--> '''Abby:''' ''(To the hitman, lying on the ground [[ScreamsLikeALittleGirl squealing]] while she stands over him) And don't look up my skirt!'' **zaps**
** Implied by Ducky to the corpse in "Toxic": "You messed with the wrong forensic scientist."
* BadassBookworm
* BerserkButton: Abby's two biggest pet peeves are people who claim to be vegetarians but still eat chicken, and poorly handled evidence.
** She is this to all of Team Gibbs. If she's missing, off they go to find her.
** In "Toxic," (Season 6, Episode 21), she insists, "What is Abby's rule #1? Do not lie to Abby."
* BewareTheNiceOnes:
** She once threatened Agent Lee that she's one of the few people in the world who can kill someone and leave absolutely no forensic evidence.
** And a couple times people tried to hurt Abby, the scene cuts to agents running to help her, and when they arrive, Abby has taken her attacker down, and is clearly coming down from a major adrenaline rush (see BadassAdorable).
** She can verbally dress you down as well as Gibbs, and in a way it's even more harsh just because it's coming from ''her''.
* BoringButPractical: Her job as TheLabRat.
** Abby would vehemently disagree.
* BrainsAndBondage
* BrainyBrunette
* BreakoutCharacter
* BunnyEarsLawyer: See PerkyGoth. Can also be something of OneOfTheKids at times.
* TheCastShowOff: Pauley Perrette has a Masters Degree in Criminal Science.
* CatchPhrase: "I hate it when he/she/they does/do that."
* CharacterizationMarchesOn: Go back and watch some Season 1 episodes, and you'll see that Abby isn't nearly as bubbly or talkative as she would later become. She also got a slight GirlinessUpgrade over time.
* CheekCopy: Admits in "Left for Dead" (Season 1, Episode 10) that she did this once.
* CheerfulChild: In a flashback we see she was an ''extremely'' cheerful tomboy with a knack for science and detective work.
* ClingyJealousGirl: Abby plays the halves of the trope title separately with [=McGee=]. The "clingy" can kick in when she's upset or worried. The "jealous" can kick in if there's a non-team member around who pulls [=McGee=]'s attention away from her (e.g. an ICE agent played by Jaime "''{{Hustle}}''" Murray). You'd swear at times that they were still dating...
* CrouchingMoronHiddenBadass
* CuddleBug
* DespairEventHorizon: When she thought [[spoiler: she isn't doing enough good to counteract all the bad]] she was horribly detracted and ''even called in sick''. Triggered when she was reminded of her very first "case": [[spoiler: When she was a child she found a little girl's teddy bear and went to return it, but due to family drama (the girl's dad hated his father-in-law who had given her the bear) the girl couldn't take it back; she even found the girl's grandpa who told her it was impossible. Eventually Abby secretly gave her one of her own toys instead and kept that bear until it fell apart.]]
* EeriePaleSkinnedBrunette
* EmbarrassingFirstName: She doesn't much care for being called "Abigail" by Ducky.
* FakeFood: The giant cup of the Caf-Pow soda that Abby frequently drinks is actually sugar-free cranberry juice; it was orginally Hawaiian Punch up until around the fourth season, when Pauley Perrette gave up eating or drinking anything that contained refined sugar.
* FirstNameBasis: Besides his wife and Gibbs, she's the only one who calls Director Vance "Leon".
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Melancholic.
* FreakyFashionMildMind
* FryingPanOfDoom: Used to great effect while helping Ziva to subdue an intruder at Gibbs' place. She even lampshades her choice of a weapon.
--> '''Abby''': It's a frying pan. It's a little cliché.
--> '''Ziva''': Works for me.
* GenkiGirl: If this were a manga, she would be most likely to SayItWithHearts.
* GirlishPigtails
** "Hit and Run" shows that she had these even as an ''actual'' young girl.
* TheGlomp
* HappilyAdopted: [[spoiler:Nine seasons in and we learn she was this to her deaf parents.]]
* TheHeart: As indicated in the character quote, again. Even those who ''know'' she isn't an easy mark will go after her first for that reason.
* HotScientist
* ICallItVera: "Major Mass Spec" and her other lab equipment. She also names her own teeth, though they appear to be masculine names - one is Frank.
* ImprobableAge: Abby was stated as being in her late twenties during season 7. And it's also been heavily implied she has a [=PhD=] in chemistry.
* IWorkAlone: For the sake of ''everyone'' involved. Including the bad guys.
* IllPretendIDidntHearThat: When Michelle Lee suggests that NCIS is better off without Gibbs in the episode "Escaped":
-->'''Abby:''' I like you Michelle, so I'm going to pretend you didn't just say that.
* KillerRabbit: See below.
* LabcoatOfScienceAndMedicine: usually unbuttoned to frame her goth outfits. Whenever she is showing her {{Wrench Wench}} attitude, she swaps it for red NCIS overalls.
* TheLabRat
* LetsGetDangerous: People who target Abby tend to wish they hadn't (via [[OffScreenMomentOfAwesome off-screen mayhem]]).
* LoveYouAndEverybody: She's a big-time hugger.
* MoralityPet: To Gibbs. He refers to her as the team mascot.
* MotorMouth: And how. It seems the more stressed she is, the faster she'll talk and the more tangents she'll go off on. Usually Gibbs has to pull her back on track.
* MsFanservice: FetishFuel, indeed.
** At the same time, her youth and ceaseless energy makes her a true KidAppealCharacter both InUniverse and out.
* MustHaveCaffeine: In the form of "Caf Pow" soda.
** She's tried to break the addiction before. It never works.
* NerdsAreSexy
* NightmareFetishist: She sleeps in a coffin.
-->'''Marty:''' You wouldn't happen to have an unhealthy obsession with death, would you?\\
'''Abby:''' Oh, no. It's just a hobby.
* OlderThanTheyLook: Pauley Perrette is 44. Abby looks maybe 25-30.
* ParasolOfPrettiness: Has a black, lacy one, that she carries in a few episodes. Speaking of which...
* PerkyGoth: If you put [[Literature/TheMillenniumTrilogy Lisbeth Salander]] and [[WesternAnimation/ThePerilsOfPenelopePitstop Penelope Pitstop]] in a blender...
* PowerEchoes: "...and I will rise up, and I will ''find'' the man that did this to Tony, and I will ''crucify him!''"
* RavenHairIvorySkin
* ReallyGetsAround: Abby's sex life hasn't gotten much attention since the early seasons, but it is known to be... eclectic.
* ARiddleWrappedInAMysteryInsideAnEnigma: See her character quote.
* SavvyGuyEnergeticGirl: Energetic Girl to [=McGee=]'s Savvy Guy.
* SheCleansUpNicely: Most notably in the HalloweenEpisode, "Witch Hunt", from Season 4, where she dresses up as Creator/MarilynMonroe in ''Film/TheSevenYearItch'', causing speechlessness in [=McGee=] and [=DiNozzo=] when they first see her.
* SherlockScan: When Abby's teaching a class on forensics for the Mexican government, one of her students looks at her and snarkily asks if she forgot when The Day of The Dead is. Abby proceeds to tell the woman that she has a cat. When the woman isn't impressed, Abby reels off a list of things she's observed that range from the woman having ''three'' cats of two different breeds, all the way to the fact that she's currently ovulating. The woman quickly shuts up.
* ShesGotLegs: "And ''don't'' look up my skirt!"
* SignLanguage: Her parents were deaf, so she's equally proficient in English and ASL.
* TeamPet
* TechnoBabble
* TomboyAndGirlyGirl: The Girly Girl to Kate and Ziva's Tomboy. Being a WrenchWench puts her in {{Tomboy}} territory, too.
* TooKinkyToTorture: Implied with Abby in "Bloodbath":
-->'''[=McGee=]:''' Now, you stay here and don't answer the door, or I will tie you up!
-->'''Abby:''' ''Really?''
* {{Tsundere}}: On any given episode she can be the sweetest, most loving and caring ball of fluff on the series and turn around to threatening anyone with the fact that she can kill them and leave no forensic evidence. Witness her Dere to Tsun turn around in the season 5 episode "Dog Tags" with [=McGee=] when she first sees [=McGee=] hurt, only to wanting to never have met him when she realized he shot a dog. Never mind that [[CrimeOfSelfDefense It Was Self-Defense]].
* WillTheyOrWontThey: Rather, will they or won't they ''again''; she and [=McGee=] used to date, and still have chemistry, up to and including being jealous of whoever the other one is currently seeing.

->'''Played By''': David [=McCallum=]
[[quoteright:325:http://static.tvtropes.org/pmwiki/pub/images/DuckyNCIS_4041.png]]
->''"I look forward to [[ImpliedDeathThreat weighing your liver]]."''

* AndStarring
* BadassGrandpa
* BowtiesAreCool: Predating Creator/MattSmith by about seven years.
* BerserkButton: In "Seadog", Ducky goes ballistic on a local LEO who contaminates a crime scene so he can get in good with the news reporter on the scene. Later in "Conspiracy Theory" we see him going at a psychiatrist whose poor standards led to one of his patients being murdered.
* BrokenBird: OK, he's not a woman. But goodness, that was even the actual name of the episode when we see just a glimpse of his past.
* BunnyEarsLawyer: His tendency to go on long speeches during work is lampshaded by Palmer when he does his first dissection. "I'm suddenly overcome with the desire to share a story of only a peripherally relevant nature."
* ClearMyName: Subverted, Ducky didn't want to clear it, but Gibbs did.
* CombatMedic: he served in the Royal Army Medical Corps and was stationed in Afghanistan and Bosnia.
* CombatPragmatist / ImprovisedWeapon: In [=S11E01=], Ducky took down a random mook with a random bowl, saving Palmer in the process.
* CoolOldGuy
* CoolTrain: Occasionally visible in the background, displayed on a small shelf is a scale model of [[http://classicstreamliners.deviantart.com/art/At-last-clear-shot-of-Mallard-169049780 LNER #4468 "Mallard"]]
** Ducky is carefully maintaining it in one episode and comments on the relationship between his name and its name.
* TheCoroner
* CreepyMortician: A very lovable kind of creepy, but still damn creepy. Gibbs finds it a useful way to break some suspects by showing them what will happen to their bodies if they refuse to cooperate and end up dead as a result. It works too.
** He is kidnapped and nearly killed by one, who begins to drain his blood before Gibbs and company arrive to save him.
* GentlemanAndAScholar: Rarely has he ever raised his voice in anger or struck someone. He uses non-physical forms of intimidation.
* HeroesWantRedHeads: The very lovely Dr. Jordan Hampton.
* LabcoatOfScienceAndMedicine: he is often shown wearing one, complete with the aforementioned [[{{BowtiesAreCool}} Cool Bowtie]]. He wears blue-green scrubs when performing autopsies and blue overalls on crime scenes.
* TheMedic: In addition to being the Medical Examiner.
* TheMunchausen: Subverted, as it seems to be generally accepted by those who know him that his stories are true.
* MyBelovedSmother: His mother had Alzheimer's and drove him crazy in early seasons; she was put in a home [[RealLifeWritesThePlot shortly after the death of her actress in late 2008]] and died a year later.
* NonActionGuy
* NoSenseOfDirection: He blames his assistants but he's always the one giving directions.
* OnlyKnownByTheirNickname: Which leads to...
** PunnyName: With a name like that, what did you think he'd be called, Mousey?
** Ari actually first thinks of the locomotive, mildly surprising Ducky.
* TheProfiler
* QuintessentialBritishGentleman: He is, of course, Scottish, but he was schooled at [[{{Oxbridge}} Oxford]]. This trope, therefore, naturally applies.
* RhymesOnADime: "Witch Hunt" has this one:
--> The sky is blue, the grass is green,
--> May we have our Halloween?
* UsefulNotes/{{Scotland}}
* ShownTheirWork: A meta-version. To prepare for the role, David [=McCallum=] went to coroner and medical examiner's conferences to learn the trade. He became so good the producers were tempted to pay him a consulting fee.
* TalkingToTheDead: He routinely does this with his "patients." TruthInTelevision: RealLife medical examiners have been known to do this.
* WhyDoYouKeepChangingJobs: He became a licensed psychologist in later seasons after we see him studying for his exams and is occasionally called-upon to profile a suspect.

->'''Played By''': Sean Murray

->'''Abby:''' ''I love it when you talk geek!''
->'''[=McGee=]:''' ''I love it that you love it.''

* AccidentalMisnaming: Suffers from all of Tony's Mc-names and being called "Probie."
* BewareTheSillyOnes: Don't let the husky size and geek-personality fool you, he is a skilled interrogator and hacker.
* BigBrotherInstinct: Will do some irrational things to protect his college-age sister, some of which have jeopardized his career once.
* BunnyEarsLawyer
* ButtMonkey
* CatchPhrase: "On it, boss." He hates it when he ends up using this for Tony, knowing he will never let him live it down.
* ClearMyName: In "Probie" he was charged with killing another cop.
* CoolCar: Had one in high school, much to the surprise of Tony. He shares in lamenting the car's demise when [=McGee=] told him of its fate.
* DeadpanSnarker: In later seasons.
* EmbarrassingNickname: He is particularly ashamed when his colleagues call him "Elf Lord" (his online gaming name).
* FairCop: Sean Murray as Agent [=McGee=] would seem to be the only one to avert this, but then he lost a good amount of weight entering Season 7, and now we can pretty much include him.
* FakeGuestStar: In season 1.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Leukine.
* HiddenDepths: A tech head, hacker and best selling author.
** Who loves the outdoors and has various skills from the scouts, including tracking abilities.
* HollywoodNerd: He plays role-playing games online, prompting the others to occasionally call him "Elf Lord."
** Somewhat justified in that his online character is named "Elflord".
* IdiotBall: When his sister showed up to his apartment obviously drugged, in a stupor saying she killed someone, and covered in blood, the seasoned investigator grabs this with a dose of BigBrotherInstinct as he doesn't take her to NCIS or even the hospital. He lets her shower and by the time she does get her blood tested, the drugs had metabolized. The Director calls him out on this, hoping it would trick him into resigning.
* LastNameBasis
* LoserHasYourBack: Plays this role once or twice in early seasons, but he's no longer enough of a loser to pull it off.
* MilitaryBrat
* MostWritersAreWriters: He's a successful author of novels inspired by his workplace and coworkers, which he writes under the name "Thom E. Gemcity." (It's an anagram of Timothy [=McGee=].)
* MrFixit: "Special Agent Goodwrench," season two, episode four.
* MysteryWriterDetective: [=McGee=] is a special agent, who wrote a best selling novel... that he would have preferred his coworkers never found out about. Later on, he was able to use his fame to get into a club that other undercover agents couldn't get in to.
* NameMcAdjective: Tony gives him a lot of Mc-nicknames to work with.
* NerdsAreSexy
* PromotionToOpeningTitles: Starting season 2.
* ProperlyParanoid: [=McGee=] never tells anyone where he works. He'll give out cell numbers, pages, etc, but he never mentions NCIS. Which is how he knows, when his new girlfriend shows up to pick him up after work, that she's not who she says she is. Overlaps with INeverSaidItWasPoison.
* RecurringCharacter: In season 1.
* RoaringRampageOfRevenge: [[spoiler:Not his own, but Ziva's, against Bodnar.]]
* SavvyGuyEnergeticGirl: Savvy Guy to Abby's Energetic Girl.
* SensitiveGuyAndManlyMan: Sensitive Guy to Tony's Manly Man.
* TenMinuteRetirement: Between seasons 10 and 11 to get the case against Gibbs dismissed.
* TheSmartGuy
* TechnoBabble
* TookALevelInBadass: Between seasons six and seven. Big time. Most exemplified in the episode "Need To Know" when he was giving the young Special Agent Dorneget tips onto how he could possibly join the Major Case Squad as well as some of Gibbs' rules.[[note]]And then Dorneget reveals he forgot his service weapon.[[/note]]
** The extra levels in badass arguably started with the sixth season episode "Caged", where he has to solve a murder case in a [[GirlsBehindBars women's prison]] pretty much on his own. Compare the phone calls he has with a car mechanic [[BookEnds at the start and at the end]] of the episode.
* VitriolicBestBuds: With Tony, behaving much like a pair of [[SiblingRivalry squabbling brothers]] at times.
* WhamEpisode: [[spoiler:Ziva is not hunting Bodnar on her own. [=McGee=] has been helping her track Bodnar's movements. The scene in which Tony finds out what they're doing is played [[DoesThisRemindYouOfAnything like he caught them sleeping together.]] ]]
* WillTheyOrWontThey: As noted above with Abby.

[[folder:Special Agent Ziva David]]
->'''Played By''': Cote de Pablo)
[[quoteright:325:http://static.tvtropes.org/pmwiki/pub/images/ZivaNCIS_3255.png]]
->'''Eli David:''' ''Use her well, Leon. Ziva is the sharp end of the spear.''

->''"Have you ever been tied up by a woman before? Did you like it? Then today's not your lucky day."''

* AccidentalMisnaming: As a trainee NCIS agent, Tony had started calling her "Probie". Gibbs had called her "Probie" on at least 2 occasions.
* ActionGirl: Ziva is (ex-)Mossad. The show frequently implies she ''used'' to be a DarkActionGirl.
* AloofDarkHairedGirl: Ziva started out this way. She gradually mellows.
* AmbiguouslyBi: Ziva [[GirlOnGirlIsHot enjoys dropping casual hints]] to Tony that she likes girls as well. [[ButNotTooBi So far she's only been seen with male lovers though]]. Mostly played for laughs or titillation.
* {{Badass}}: Early on in Ziva's tenure at NCIS, she is not allowed to participate in taking down suspects. Another woman comments on the presumed chauvinism of this. Ziva replies that Gibbs is actually afraid she'll ''kill the suspect by mistake''.
** Then it [[FunnyAneurysmMoment happened]]. Several times. [[labelnote:First]] Once when chasing an overweight suspect who has a heart attack when climbing some stairs. She's chastised despite it not being her fault, but mostly out of frustration at losing a lead and it doesn't last the scene.[[/labelnote]] [[labelnote:Second]] And again, much more serious, when she punches an obnoxious suspect in the neck, causing him to drop dead despite her insisting that she does know her own strength and couldn't have killed him. [[spoiler:Ducky finds a blood clot in his brain that could have been released and gotten lodged there by the punch, but ultimately rules Natural Causes.]][[/labelnote]] [[labelnote:Third]] Ilan Bodnar, but whether that was accidental is debatable.[[/labelnote]]
* BadassIsraeli: ''Mossad''.
* BecomingTheMask: [[spoiler:It is suspected by Leon Vance at the end of season 6 and confirmed by Ziva in early season 7 that she was ordered by her father to kill Ari in order to gain Gibbs' trust and spy on the team. By the end of season 3, her crying over Gibbs' life threatening condition shows she has become closer to her targets than a cold assassin ought to be.]]
** From "Broken Arrow"
-->'''CHASE''': "Does Agent David carry a weapon?"
-->'''GIBBS''': "She is a weapon."
* BelligerentSexualTension: With Tony.
* BerserkButton: A couple, but ''God help you'' if you hurt Tony.
* TheBigGuy:
* BookEnds: In Ziva's debut episode, the first character she meets is Tony. In Ziva's final episode, the last character she interacts with is Tony.
* BrainyBrunette
* BrokenBird: [[spoiler: Considering she was held captive in Somalia and tortured for months]], she covered it ''extremely'' well. [[spoiler: In the season 11 opener, she finds that she no longer can, and this leads to her leaving NCIS for good.]]
* BluntMetaphorsTrauma: A RunningGag is her regularly messing up american figures of speech.
-->"American idioms are driving me up the ''hall''."
* BunnyEarsLawyer:
* ClearMyName: The first episode of season 4 dealt with this issue.
* ConflictingLoyalty: As of the end of season 6, she is torn between her loyalty to Mossad and her father, and Gibbs and [=NCIS=]. [[spoiler:She picked Mossad and ended up caught by a terrorist and tortured to be saved by Gibbs and the team. In retrospect, she realizes she made the wrong choice, and decides to stay in the United States from then on and becomes a US Citizen so she can become a bonafide NCIS agent.]]
* DefrostingIceQueen
* DoesNotKnowHerOwnStrength: See Badass.
* DrivesLikeCrazy: Director Shepard once said of her, "I think she was an Eastern European cab driver in a past life."
-->'''Vance:''' Most fathers teach their daughters to drive. I have you to blame for this?\\
'''Eli David:''' This she learned from her [[JewishMother mother]].
** One of her notable driving habits is doing 80 in a 40 zone, as was noted on her speeding ticket.
* ExtremeMeleeRevenge: [[spoiler: How Ilan Bodnar bites it.]]
* FairCop
* FakeGuestStar: In season 3.
* FeminineWomenCanCook: Averted. While very much the manyl ActionHero, she can cook quite well. According to Abby in the episode "Caged", "Her cooking rocks!"
* FireForgedFriends: With the exception of Abby, Ziva truly became close to the team after enduring some difficult investigations.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Phlegmatic
* FunnyForeigner: Downplayed. She's serious except for her tendency to butcher English-language quotes or figures of speech.
* HeroicBSOD: [[spoiler:The final straw is an attempt on her life by a terrorist cell that drives her off the grid. This leads to her departure from NCIS in the Season 11 opener.]]
* [[IHaveNoSon I Have No Father]]: To the point of changing nations just to give him a TakeThat.
* InformedJudaism: Though considering her former profession as a Mossad operative, strict adherence to almost ''any'' religion would be tough. Pointedly, she has on occasion turned down food allegedly because it's not kosher, but she has no problem with pepperoni pizza.
* ImprobableAge: Ziva David is less Improbable Age and more Impossible Age. She joins the show in her early twenties, supposedly after she's graduated high school, served her two years in the IDF, attended college, applied for Mossad, become immediately tapped for inclusion into an elite and highly competitive special operations unit with a training period of several years, and still have enough time to become "an experienced agent" with multiple missions under her belt. And this is at a age the youngest CIA intelligence officers would be beginning training. (It's worth pointing out, however, that she is the daughter of the Director of Mossad, and it is heavily implied that she was all but [[TykeBomb raised from the cradle to be a Mossad operative]].)
* ItIsPronouncedTroPAY: As she has pointed out, her last name is pronounced "Dah-VEED," not "David."
* KillTheOnesYouLove: Ziva is forced to do this to her half-brother Ari.
* KnifeNut: Ziva is one of the few people in the world who can kill you reliably with a thrown knife. She has demonstrated this.
* TheLadette: She rotates between this and;
* LadyOfWar
* [[LastMinuteHookup Last Minute Kiss]]: [[spoiler:With Tony in her final episode.]]
* [[LockedInAFreezer Locked In A Shipping Crate]]: With Tony in "Boxed In".
* MaamShock: Another BerserkButton.
* MacGyvering
* {{Malaproper}}: Her messing up quotes, again; this is the main reason she qualified as a FunnyForeigner.
* MataHari
* MilitaryBrat
* MsFanservice: Sort of. She's had some big moments, but much less frequently than Abby.
* MyNaymeIs: "David" has the earlier pronunciation (just as it appears, and as an iamb), rather than the Anglicized, trochaic "Dei-vid."
* [[NiceHat Nice Orange Cap]]: Her TragicKeepsake.
* OneOfTheBoys: She likes to hang around men in a nonromantic wolf-in-the-pack sort of way and she takes great pride in her skill at [[ARealManIsAKiller manly things]].
* {{Omniglot}}: She speaks ''at least'' nine languages, including the language of love.
* PhotographicMemory: ''Very'' useful in her line of work as agents who don't develop this tend not to last long in Mossad.
* [[ProudWarriorRace Proud Warrior Race Gal]] : Because she is a BadassIsraeli.
* PutOnABus: Cote de Pablo left the series after season 10, unable to come to terms with her contract. Ziva, emotionally torn up by the attempt on her life, decided to leave NCIS and stay in Israel off the grid.
* [[ARealManIsAKiller A Real Woman Is A Killer]]
* RoaringRampageOfRevenge: against Ilan Bodnar, and unsubtly enough to draw attention from the CIA. [[spoiler:And roped [=McGee=] into helping, behind Tony's and Gibbs' backs. But in the end, she gets him in a NoHoldsBarredBeatdown.]]
* ScrabbleBabble: Subverted one time she played [=McGee=] in Scrabble. With the last Q at a corner of two Is, she makes Qi twice, read 'Chi'. Doubles as UnderdogsNeverLose as she came back from a 50 point deficit earning 62 points.
* SuspiciouslySimilarSubstitute: In season 3.
* TomboyAndGirlyGirl: The Tomboy to Abby's Girly Girl.
* TragicKeepsake: Ziva's orange cap; [[spoiler: it's a reminder of the victim from "Dead Man Walking".]]
* UnresolvedSexualTension[=/=]WillTheyOrWontThey: Done ''to death'' with Tony. (The writers seem to enjoy dropping hints that in fact they ''have'', but this is ''probably'' not canon.)
** TheyDo.
** Michael Weatherly has stated that a kiss was filmed quite a while ago, and was never aired.
* VerbalTic: Has a slight habit of forming questions as statements with "yes?" tacked on the end.

* GeniusBruiser: He was once a boxer, but can compete with [=McGee=] in knowledge of cryptology.
* HappilyMarried: [[spoiler:Until his wife is murdered.]]
* DeadPersonImpersonation: It's heavily implied in one episode that he is not the real Leon Vance, but an old boxing acquaintance thereof, and that the two switched identities at some point in the past.
* ItsPersonal: Twice he has caused an interrogation to get out of hand because someone close to him was murdered and a suspect was in the hot seat.
* MysteriousPast: Subverted, not all of it has been explained...yet.
* OralFixation: Chewing on toothpicks.
* ScaryBlackMan: He can be absolutely terrifying when he wants to be, which is probably one of the reasons he gets to boss Gibbs around. Taken to severe extremes when he put a fire safety axe through a metal table in the interrogation room to intimidate a teenage suspect who was suspected of killing one of Vance's friends.

* ActionSurvivor: He works out in a gym but he isn't combat proficient.
* {{Adorkable}}
* BrainyBrunette
* ButtMonkey: If there's a chance for a character to be insulted or put-upon in any given episode, there's at least a 75% chance it'll be Palmer.
* TheConsigliere: It's revealed in one episode that whenever Tony is left in charge of a case, he secretly has meetings with Palmer to help point him in the right direction whenever Tony feels that he's lost on what to do next.
* CrouchingMoronHiddenBadass: Is very intelligent and a good assistant to Ducky, but has problems with self-confidence.
* ExactWords: He uses this on Gibbs during his CrowningMomentOfAwesome (see the page), pointing out that he technically stayed in the car as he was ordered.
* FakeGuestStar: Might as well be a TropeCodifier. Dietzen was credited as a recurring guest star for the first 5 seasons and as "Also Starring" from season 6 onwards. Is even on the cover art for the Season 8 DVD but wasn't made a main cast member until Season 10.
* {{Fetish}}: He apparently has a thing for boots.
* TheGlassesComeOff: During his CrowningMomentOfAwesome.
* HappilyMarried: To Breena in Season 10.
* HollywoodNerd
* LovedINotHonorMore: He tells his love that while he loves her more than anything, his TrueCompanions were in trouble and he needed to go and help them, even if it meant moving the wedding up to a sooner date (within the hour) and then come back for the honeymoon. She completely understands.
* {{Megane}}
* MyHovercraftIsFullOfEels: His story about spending time in France features a downplayed example: He was trying to tell some French friends of his how his mother used to hunt squirrels when he was a child, but he mixed up the French word for "squirrel" with the word for "shark".

* PersonAsVerb: In a CallBack to his CrowningMomentOfAwesome, an [=NSA=] agent is mentioned as having "pulled a Palmer" in an 11th season episode.
* PromotionToOpeningTitles: After eight seasons on the show, Brian Dietzen was finally upgraded to a series regular in season ten.
* RecurringCharacter
* RecklessGunUsage: Palmer has no actual firearms training so it almost results in IJustShotMarvinInTheFace with Ducky in the season 10 episode "Detour".
** Ducky, whose military training may be decades old, is smart enough to carefully push the gun away from his face and avoid being accidentally shot.
* {{Retirony}}: Subverted. One moment, Jimmy's talking with Agent Barrett about his recent engagement. Seconds later, the Port-to-Port Killer is loose and violently kidnapping Jimmy and Barrett. However, Gibbs saves the day, and Jimmy ends up surviving the episode with only a few scratches.
* ThatCameOutWrong: Happens to him a lot, and when he tries to explain, [[DiggingYourselfDeeper he just looks worse]].
* TooKinkyToTorture: When he helps Abby solve a problem, Gibbs gives Abby a peck on the cheek and Jimmy [[DopeSlap a Gibbs slap]]. He looks just as pleased at this as Abby. Though that might have been because the slap meant that Gibbs considered him part of the team.
** In an earlier episode, Ducky mentions that his attempts to emulate the [[DopeSlap "Gibbs' Slap"]] on Palmer were ineffective, as he seemed to enjoy it.

* AwesomeByAnalysis: What she did at the NSA.
* AmbiguousDisorder: Has several signs of AspergersSyndrome.
* BunnyEarsLawyer: Tends to create "nests" where she works, which is often on the floor rather than a desk (or sometimes ''on'' her desk). Also associates key details of situations and her surroundings with foods she was eating at the time.
* DumbBlonde: Inverted. She's a brilliant NSA analyst who predicted several security breaches years in advance.
* HappilyMarried: Points out to Tony that she has a ring when he asks if she's married.
* HollywoodNerd: Almost always has a notebook computer with her.
* [[spoiler:HoneyTrap]]: Implied to be how Bishop became the NSA's expert on Benham Parsa. (Arguably subverted though - the NSA does number crunching, not field work, so this got Bishop yanked off the case.)
* MotorMouth: When she gets going, she could give Abby a run for her money.

An up-and-comer in the [=DoD=] Office of the Inspector General. He has Gibbs arrested for his questionable methods, hoping to use his prosecution as a launching pad for his own career.

* {{Blackmail}}: [[spoiler:Engaged in lots of it to worm his way into his current lofty position.]]
* CondescendingCompassion: To Ziva in the tenth season finale. He tells about how much he "sympathizes" with her over the murder of her father right before taunting her about his about his ultimate goal of bringing down Gibbs, who he acknowledges is the only father figure she has left.
* EvilCounterpart: Tony quips that he's like [=McGee=]'s evil twin. [[spoiler:He turns out to be less "evil" and more "too ambitious for his own good".]]

* HeelFaceTurn: After he [[spoiler: gets a front row seat for the bomb that killed [=SecNav=] Jarvis and seriously injured DHS Secretary Morrow.]]

* ItsAllAboutMe
** BreakTheHaughty: [[spoiler:Coming within feet of being blown up can do that.]]
* JerkAss
* ObfuscatingStupidity: So freaking much. He starts off seeming nice but comically annoying. He ''quickly'' shows that he is not to be taken lightly and stays one step ahead of the team.
* OutGambitted: [[spoiler:Gibbs is conveniently sent on assignment abroad before having to testify, and his team all [[TenMinuteRetirement turn in their resignations]] to accept responsibility for him. Documents about Mike Franks and the murder of the drug lord that killed Shannon and Kelly are burned and shredded, effectively yanking the rug out from under Parsons' case.]]

* BadassGrandpa

* HeroOfAnotherStory
* LikeAnOldMarriedCouple or maybe HeterosexualLifePartners with Gibbs. This scene from [[http://www.youtube.com/watch?v=BF-qyJGAvCI "Short Fuse"]] says it best...
** Then there's this exchange in the Season 11 premier:
-->'''Fornell:''' You know I'm not going to kiss you goodnight.\\
'''Gibbs:''' What?\\
'''Fornell:''' You're walking me to my car. We breaking up?\\
'''Gibbs:''' If I could, I would. Unfortunately, I trust you.

[[folder: Army CID Agent Lt. Col. Hollis Mann]]
->'''Played By''': Creator/SusannaThompson

-->''"If this is going to turn into a pissing match, you'd better bring an umbrella."''

* DistaffCounterpart: To Gibbs. She's even a team leader in the Army's corresponding agency, Army Criminal Investigation Division - [[FunWithAcronyms yes, that spells what you think it does]]: usually referred to as Army CID.
* EveryoneCanSeeIt: Her {{UST}} with Gibbs is noticed by the whole team.
** Upon meeting Mann for the first time, Vance asks Gibbs if she's one his ex-wives.
* [[FieryRedhead Fiery Strawberry Blonde]]
* GirlOfTheWeek: Subverted; she appears to be this at first, but it takes her and Gibbs two episodes to get together and they remain together for almost a year. In fact, she's easily the most long-term love interest Gibbs has had on the show.
* HandsOnApproach: Gibbs does this to her in "Grace Period." She doesn't seem to mind that much.
* HeroOfAnotherStory: Her career with CID could easily have been the basis for a SpinOff.
* JurisdictionFriction: This is how she meets Gibbs and what brings them back together.
** It happens again when she returns from Unretirement.
* LoveInterest: To Gibbs in her first run of apperances. [[spoiler: She later married someone else.]]

[[folder:CGIS Agent Abigail Borin]]
->'''Played By''': Diane Neal

* AmbiguouslyBi: In "Oil and Water", she and Tony are chasing a suspect, which she [=KOs=] with a left-handed swing of an oar. Her explanation is...interesting.
-->'''Borin''': College softball.
-->'''Tony''': Southpaw?
-->'''Borin''': I swung both ways.
* {{Badass}}
* BerserkButton: Don't joke about blowing stuff up. Her temper's much more explosive.
* BrokenBird: [[spoiler: Her lover was killed in an IED explosion with two other marines. She had to pull his mangled body out of the water.]]
* CoastGuard
* DistaffCounterpart: To Gibbs, to the point that the ''entire team'' lampshades it. So naturally the following apply:
** DeathGlare
** DopeSlap
** GutFeeling
** MustHaveCaffeine: It's implied she and Gibbs even take their coffee the same way.
** RuleNumberOne: Never make excuses.
** RightBehindMe
* {{Expy}}: This is an extreme case of ActorAllusion, but Borin is pretty much [[Series/LawAndOrderSpecialVictimsUnit ADA Casey Novak]] as a cop, minus the emotional trainwreck [[spoiler: but it looks like she could be headed that way]]. It's more than likely some of her lines are recycled. Bonus points for the softball playing and [[AmbiguouslyBi commentary on her swinging]].
* FairCop
* HeroOfAnotherStory
* PerpSweating: At one point, she and Gibbs double team someone.
* OnceASeason: She proved to be so popular that her appearances tend to be this. [[LampshadeHanging Lampshaded]] really, really hard at the end of one of them:
--> "Same time next year, Gibbs?"
* OneSteveLimit: Conspicuously averted with a not exactly common name. Causes some confusion occasionally when both she and Sciuto are in the same room.
* StatuesqueStunner

[[folder:Dr. Samantha Ryan]]
->'''Played By''': Creator/JamieLeeCurtis

At work, a creepy-as-hell [=DoD=] psy-ops expert who's almost a match for Gibbs in the mindgames department. At home, a single mother with a divorce from an abusive husband in the past. Needless to say, she and Gibbs hit it off very well. As of the end of season 9, in hiding after CEO-turned-terrorist Harper Dearing got her abusive ex sprung from prison.

* BelligerentSexualTension: With Gibbs. They match very well, but they put each other on the defensive so frequently that some of their interactions can be quite angry.
* {{Gaslighting}}: What Ryan does for a living, and not just to military targets.
* PutOnABus
* RiddleMeThis: She always tells Gibbs what she thinks he needs to know, but for some reason always does so in the most infuriatingly roundabout ways possible. (One tip was delivered on the inside of a pizza box.) Gibbs does not like this.
* SilverFox: Jamie Lee may be the most triumphant example for women right now.

!Mossad
[[folder:Mossad Director Eli David]]
->'''Played By''': Michael Nouri

-->''"Tell me, Leon. Are we winning?"''

Ziva's father and head of the Mossad. He is utterly ruthless in his pursuit of Israel's enemies, often using the same illegal tactics as them to hunt down and kill them.

* [[AbusiveParents Abusive Parent]]: He uses his own children as tools in his schemes. [[spoiler:One (Ziva) ends up killing another (Ari Haswari). On Eli's orders.]]
* AccidentalPublicConfession: [[spoiler:Performs one because Tony goaded him not just on Ari turning traitor but an apparent habit for his agents to go rogue in general. He admits none of his men ever do something without his say, including the one Tony just killed in self-defense. The second worst part for Eli, first being Ziva saw this, is Tony was originally being interrogated by him and the guy turned it around without Eli realizing it.]]

** BadassGrandpa
** BadassIsraeli
** BadassLongcoat
** CulturedBadass

* FallenHero
* FatalFlaw: PatrioticFervor.
* HeWhoFightsMonsters: Eli is easily as bad as the terrorists that he fights, to the point that [[spoiler: he drives his own son into becoming one]].
* KnightTemplar
* MoralMyopia: He has repeatedly violated Israel's treaties with the USA by ordering operations on US soil, which have resulted in Mossad agents killing a number of American federal agents. When Tony is forced to kill a Mossad agent who resisted being arrested for the murders he committed under Eli's orders, Eli treats it as a horrible offense against Israel by the USA and tries to have Tony extradited.
* RatedMForManly
* RedemptionEqualsDeath: [[spoiler:To what extent is arguable, considering that before his death, he murdered a witness to his entry into the US as part of his "redemption".]]
* ShellShockedSenior: He shows weariness with the world of intrigue with every breath.
* TheSpymaster
* TwoFirstNames
* WasItReallyWorthIt: Seems to be asking himself this. His actions ultimately turn both of his children against him.

[[/folder]]

[[folder:Orli Elbaz]]
->'''Played By''': Marina Sirtis

Eli David's replacement as the head of Mossad. She doesn't get along with Gibbs right out of the gate.

* YourCheatingHeart: Had an affair early in her career with Eli David that led to David's divorce from his wife, and years of bad feelings from Ziva. Ziva had considered Elbaz to be sleeping her way to the top, but reluctantly admitted that she may have genuinely loved him when she came to the US to see what was going on with the murder investigation.

* EvenEvilHasLovedOnes: Ziva still loved him, even after what he had done. [[spoiler:And he had an Israeli doctor and childhood friend he loved and planned on proposing to before BecomingTheMask.]]
* EvenEvilHasStandards: He found Gerald's inability to drive Ducky's vintage Morgan painful to listen to or see.
* EvilCannotComprehendGood: His fatal mistake was that it didn't even occur to him that Gibbs would really trust Ziva to watch his back and assumed Gibbs was alone when he confronted him.
* GeniusBruiser
* GoneHorriblyRight: His father raised him to be a monster... who hated him for it and did everything he could to destroy what his father had worked for.
* HeroKiller: The series' first. [[spoiler: He even killed Kate to prove it.]]
* RevengeByProxy: He [[WomenInRefrigerators stuffs]] [[spoiler:Kate]] into the fridge and tries to do the same to Abby, aware that it's the best way to make Gibbs suffer. He also tries to kill Jenny, snipes at [=McGee=] (who lucks out by unknowingly moving out of the way at the last second), and tries to kidnap Ducky. The only member of Team Gibbs he doesn't single out is Tony.

* FakingTheDead: Tries this to escape NCIS in the premere of season ten by blowing up a car with his brothers remains inside. Gibbs doesn't buy it and manages to uncover the truth.
