[[caption-width-right:300: From left to right: Train, Sven, Eve, and Rinslet.]]

''Black Cat'', by manga artist Kentaro Yabuki, centers around a pair of {{bounty hunter}}s, also known as "Sweepers", Train Heartnet and Sven Vollfied. Perpetually struggling for cash and jobs, they each harbor a secret: Sven is a former agent of an international police force, and Train used to be XIII, a deadly assassin for the world-spanning organization Chronos.

They would be content to just live out their lives chasing bounties and living a carefree lifestyle, but Train's old life has a habit of catching up to him: former partner Creed Diskenth is attempting to overthrow Chronos and take over the world with his own group, the Apostles of the Stars. And Creed wants Train to join him, no matter the cost. And did I mention that Creed killed the woman who convinced Train to abandon the assassin's lifestyle?

Allied with world-renowned cat burglar Rinslet Walker and living bioweapon Eve, Train and Sven try to live a carefree life even as both Creed and Chronos attempt to drag both into an escalating global conflict.

Now available on [[http://www.hulu.com/black-cat Hulu]] in subbed and dubbed format. ([[NoExportForYou If you live in the U.S.]])

Not to be confused with the same-named MarvelComics character. Or the horror movie ''Film/TheBlackCat''. Nope, not even Creator/EdgarAllanPoe's poem.

----
!!This series has examples of:

* AbsurdlySharpBlade: Eve turns her hair into two of these in the final assault, but the first time she used it she overdid the work and rendered two mooks naked instead.
* AdaptationExpansion: At the cost of cutting out certain aspects of the manga plot, the anime added an entire arc towards the end of its run that sought to tie together the significance of Eve's origins and the work Dr. Tearju did, along with providing some background on The Doctor. Add to that several of the Chrono Numbers who appear in the anime only and it's kind of sad that they had to sacrifice much of the manga's character development. It truly could have been awesome. On the other hand, Train and Saya's relationship was much more developed in the anime, making Train's motivation more moving.
* AllLoveIsUnrequited: This series really actually has very complicated romantic relationships, and pretty much every one of them is unrequited. Most of it is [[StupidSexyFlanders Stupid]] [[EvenTheGuysWantHim Sexy]] [[CelibateHero Train's]] fault, though...
* AmbiguouslyGay: Creed is never stated outright to be gay... but... well, you know.
* AGodAmI: Creed in the story´s final.
* AncientConspiracy: Subverted, Chronos is actually out to ensure peace and prosperity and most of the members that are met are quite nice and caring.
** Their methods do tend to be on the KnightTemplar side of things however, even Train refers to the organization as a necessary evil.
** ...and played straight in anime where [[spoiler: some members are trying to achieve an AssimilationPlot.]]
* AnimalMotifs (Oh, have a ''guess''. Here's a hint: [[ExactlyWhatItSaysOnTheTin It's right there in the title of the series]].)
* TheAntichrist: Creed, who compares himself to Lucifer.
* {{Anticlimax}}: In the manga, Train getting turned into a kid via nanomachines is a serious issue, requiring him to visit Eve's creator to figure out how to reverse it. In the anime, Tearju is missing from the series until the anime's GeckoEnding, so Train just...gets better. Somehow.
* AntiHero or AntiVillain: Most of Chronos numbers, varies Between UnscrupulousHero, NominalHero and WellIntentionedExtremist.
* ArmorPiercingSlap: Sven to Train, Rinslet to Jenos. Remember that the receivers are Chronos numbers.
* AwesomeMcCoolname: [[SharpDressedMan Charden Flamberg]], [[AxCrazy Kranz Maduke]], [[PosthumousCharacter Zagine Axelox.]], [[TeamDad Sven Vollfied]] and [[IdiotHero Train Heartnett]] all have very cool sounding names.
* AxCrazy: There are a number of these in the series. Creed has more than a bit of Ax-craze, Durham and Gyanza qualify, and two of the Numbers [[spoiler: are obviously insane and bloodthirsty, and will even attack their own comrades]]. Neither Creed's gang nor the Numbers like their bloodthirsty comrades.
** [[spoiler:The two aforementioned Numbers are far and away the most psychotic. At one point in the manga, another number mentions that they’ve wiped out towns in order to kill their target.]]
* BadassBeard - Many male characters have beards, and most that do are good guys.
** In the original pitch of the series, Sven had a beard, which was degraded into (still BadAss) PermaStubble.
* BadassBookworm: Eve, who reads hundreds of books and remembers each one.
* BadassLongcoat: Belze, Train (while still with Chronos) and Sven (while still with the IBI.)
* BadassInANiceSuit:
** Sven.[[note]]Fedora included.[[/note]]
** Train on Occasion.
** Even Eve gets a few shots of her wearing Sven's suit.
* BadBoss: Creed, although Chronos is rather Machiavellian at times, and Sephiria says that she'll become the devil himself if she has to.
* BaldOfAwesome - Nizer
* {{BFG}}: Beluga's rather large bazooka, "Verethragna."
* {{BFS}}: A very subtle subversion. Creed's Imagine Blade can easily slice through helicopters, but doesn't actually have a blade. It's only the hilt of a blade broken by Saya.
* BigEater: Train actually manages to use up millions of dollars from hard earned bounties on food.
* BishieSparkle: Charden when he takes off his glasses, Train a few times in his more lighthearted bits.
* {{Bishonen}} : [[http://static.tvtropes.org/pmwiki/pub/images/train-animestocks-090.jpg Train]], [[http://static.tvtropes.org/pmwiki/pub/images/blackcat_creed_25.jpg Creed]], and [[http://static.tvtropes.org/pmwiki/pub/images/janus.jpg Jenos]] may all fit this description. The winner of them all is chipper assassin [[http://static.tvtropes.org/pmwiki/pub/images/lin_shao_lee_grin.jpg Lin Shaolee]], who is the prettiest person in the series (including the girls).
** What about [[http://static.tvtropes.org/pmwiki/pub/images/charden_6779.jpg Charden?]] Kyoko goes all blushing fangirl when he takes off his glasses the first time.
* BlandNameProduct - the Playcube video game console that Train and Eve use to get a message from Glin.
* BlastingItOutOfTheirHands: Train does this a lot.
* BloodyMurder - Charden's Tao power is the manipulation of blood, usually his own.
* BountyHunter: The three central characters, plus a lot of secondary ones.
* BreadEggsMilkSquick: It is stated that the Doctor's hobbies include playing go and vivisection.
* BulletTime: Sven gained this ability near the end of the series
* CaptainErsatz - Many characters appear to have been borrowed wholesale from other manga. Train is a lot like [[RurouniKenshin Himura Kenshin]], [[CowboyBebop Spike Spiegel]], and [[{{Trigun}} Vash]]... ''CowboyBebop'' seems to be the most obvious one: Creed is a bit like Vicious, Jet is like Sven, Faye is similar to Rinslet...
** Eve and Kyouko get [[{{Expy}} Expies]] of themselves in ''ToLoveRu''. More recently, Train received an expy in ''ToLoveRu''.
*** Understandable, of course, because the two have the same artist, and an assistant on ''Black Cat'' is the writer for ''To-Love-Ru''.
** [[http://images1.wikia.nocookie.net/__cb20090710200558/blackcat/images/c/cb/Creed%3B_Alternate_Profile.jpg Let's be honest.]] [[VideoGame/FinalFantasyVII Who's the first character you think of when you see Creed?]]
* CareBearStare - In the anime, apparently Train's Orihalcum bullet from his railgun shot against Creed acted as this, causing [[spoiler: Creed's sudden HeelFaceTurn]].
* CatSmile - Train, during more comedic moments, and Kyoko, occasionally.
* CelibateHero - Train isn't attracted to Rinslet, Kyoko, Creed, or pretty much any girl or guy he ever meets. And even with Saya, it is revealed canonically that he only saw her as a close friend.
* ChickMagnet - Train. Kyoko, Saya (what "close friend" invites a guy to a (romantic) evening looking at fireworks?), and even Rinslet develop very obvious feelings for him. You just know that Jenos wouldn't even have a chance with Rinslet if Train showed at least the smallest sign of reciprocating her feelings.
* ClassyCatBurglar - Rinslet.
* {{Cloudcuckoolander}} - Apostle of the Stars member Kyoko Kirisaki, who seems to have only the vaguest idea what is going on around her at any given point. It's cool, though, she [[GenkiGirl doesn't let that get her down]].
* ContractOnTheHitman - Train
* CrazyJealousGuy: Creed to Train, especially with his attitude towards Saya.
* CrazyPrepared: Belze´s (Number II) [[spoiler:fireproof]] coat, Sephiria´s (Number I) bracelet. [[spoiler: It explodes upon her death, killing the target.]]
* CrystalDragonJesus - Given the alternate-universe nature of the world it takes place in, this is surprisingly averted. The first scene of the anime (ignoring the foreshadow sequence that precedes the opening sequence) explicitly takes place in a church, with a man praying to Jesus for mercy.
* CuteBruiser - Eve is tiny, adorable, a bookworm, and she can kick your ass.
* CuteLittleFangs - Train, again.
* DeathDealer - Number IX David Fapper in the anime
* DefeatMeansFriendship: Whenever Train or the other main characters beats one of the Apostles of the Stars, they convince them to give up their life of crime and some even come back to help later.
* DisguisedInDrag - Both Train and Sven end up in women's clothing at one point, Train because his body got de-aged for a while and Eve's clothes were all that fit him, and Sven because he had to pose as a woman to lure out a bounty. AttractiveBentGender is very much averted, as he points out.
* DisposableWoman - Saya was pretty much introduced just to give a reason why Train is at odds with Creed.
** More so in the anime than in the manga, where her spirit visits Train and helps him out.
* DistractedByTheSexy - Leon, [[GirlsHaveCooties weirdly]]: during his fight with Eve, she emerges from underwater transformed into a mermaid, wearing only a SeashellBra and sporting a surprisingly developed body for her age (however, it may be just her shapeshifting abilities in action). [[http://www.youtube.com/watch?v=nz1VtXbsbh0&feature=player_detailpage#t=107s His reaction and the following shot, showing Eve from his perspective, tell everything.]]
* DoesThisRemindYouOfAnything - Quite a few fight scenes between Train and Creed, and the dialogue between them doesn't help. "That's it... my Heartnet..."
** Let's now forget Kyoko vs Belze in the manga. While caressing and licking his spear she says "So hard, so dangerous, but it'll melt in my mouth."
* DogFoodDiet: Train and Sven have this (especially in the anime, where it's shown they rely on eating bread crust leftovers from a waitress).
* DoNotDoThisCoolThing - Anime-only: How Train was shown to be much cooler and {{Badass}} before he became a pacifist.
* EffeminateMisogynisticGuy: Dean Slakthy is considered so {{bishounen}} that it's hard to tell he's male until he starts ranting about how much he hates women.
* ElegantGothicLolita: Eve has a particular predilection for black lace dresses, tights and silver cross jewelry.
* EpicFlail: Baldor from Chronos not only uses a flail, but one that is powered by rockets for additional awesomeness.
* EvenTheGuysWantHim - Train has many female admirers and one very obsessed male admirer who refuses to take "no" for an answer.
* EvilCannotComprehendGood: Played straight and inverted. Creed just can't understand why Train wouldn't want to join him... or why Train would be upset at all his attempts to MurderTheHypotenuse. Meanwhile, in part due to being ObliviousToLove, and in part due to leaving his own time as a sociopath behind him, Train can't understand just why Creed would do the various evil acts he does throughout the series.
* EvilHasABadSenseOfHumor
* EvilutionaryBiologist - Tao, nanites... whatever can give him power, Creed wants it and wants to use it on his followers.
* ExtremeDoormat: Train in the anime was this for quite a few episodes during his time in Chronos.
* EyepatchOfPower: Sven's eyepatch isn't there because he's missing an eye, but because he has a magic seer's eye that can see a few seconds into the future.
* FaintingSeer: Early in the series, since Sven never really used his precognitive powers much and doesn't have much control over them, he gets noticeably exhausted no matter ''what'' he sees. As the series progresses and control over his abilities becomes more important, he gradually starts to get over the FaintingSeer syndrome.
* FatalAttractor: Train isn't very lucky when it comes to love interests... this might be a contributing reason to why he [[CelibateHero isn't interested in romance]].
* FountainOfYouth: Creed [[spoiler:wants to use nanites to make himself immortal forever.]] Also Train [[spoiler:gets temporarily deaged by nanites...]] which is less fun than it seems, since he can't [[spoiler:fire his gun properly.]]
* FourEyesZeroSoul: Averted with Charden, who's probably the most sane member of the Apostles. The Doctor, on the other hand, plays this straight.
* GeckoEnding: A very bizarre case, as the anime actually does get to the end of the manga, and then suddenly a new arc comes out of nowhere with only one very minor piece of foreshadowing ([[spoiler: Rinslet finding a CD with the word "Eden" printed on it,]]) to keep it from being a complete AssPull.
* GentlemanThief: Rinslet could be seen as a female version of this.
* AGlassOfChianti: Creed has one of these in the manga, complete with a rose in it.
* AGodAmI: Creed does this after he [[spoiler: uses nanomachines to make himself immortal]].
* GondorCallsForAid: Final few episodes of the anime, during the Eden arc. [[spoiler: Train literally calls upon every single character ever introduced that isn't dead and/or directly allied with Mason to assist with Eve's rescue.]]
* GoodGuyBar: The bars where Sweepers can trade information on targets.
* GreenLanternRing - Eve's shapeshifting powers wind up turning into this as her imagination develops and she thinks up new ways to make herself useful.
* GunKata: Train's fighting style.
* GunsAkimbo: Kevin's fighting style.
* TheGunslinger: Mostly Train, but Durham fits the classic Western image (minus the beast mask).
* HandicappedBadass: Kranz is completely blind...[[ImplausibleFencingPowers and can slice bullets in half]]...[[KnifeNut with a knife.]]
* HandsomeLech: Jenos. He tries so much to be TheCharmer, but always fails despite his above-average looks.
* HeelFaceTurn: Eve, [[spoiler:Kyoko]] and [[spoiler: in the anime, Creed.]]
* HellishPupils: Train's eyes, even in their normal state, are this. Presumably to maintain the "cat" theme.
* HeterosexualLifePartners: Sven and Train are definitely this.
* HeWhoFightsMonsters: Baldor and Kranz definately, Sephiria may even apply, in fact the entire organization of Chronos can pretty much qualify.
* HitmanWithAHeart: Train, ''definitely''.
** Describes most of the Numbers, actually. Except for the AxeCrazy ones, the Numbers tend to be rather nice compassionate people (Belze, Jenos, Shaolee, Sephiria) who still kill their targets.
*** Err... in the manga at least, Shaolee ''seems'' kind of nice and caring, especially to River and the Sweeper Alliance thing, until you finally see him fight... and gratuitously dismember one of his opponents, leaving him alive long enough to tell him basically "well, aren't you just unlucky to fight ''me''." ''Then'' he kills him. Jenos is freaked out, which tells you something for a Number. And Jenos is a guy who uses RazorFloss for a weapon!
*** Also, Sephiria [[spoiler: has some [[ManipulativeBastard Manipulative Bitch]]-like tendencies: such as reminding Train about what happened to Saya so he would hunt down Creed, using the Sweeper Alliance as a decoy, knowing full well that some of them might die and acting like a total bitch towards Rinslet. Her polite moods are a reminder to BewareTheNiceOnes.]]
* HyperactiveMetabolism - Train manages to eat huge amounts of food (including a giant plate of deep-fried bread crusts) and still remain stick thin.
* HyperspaceMallet: reconstructed by Eve since the mallet doesn't actually come from hyperspace
* IAmNotLeftHanded: Although he's trained himself to be ambidextrous, Train switches to his originally dominant left hand in a fight with Creed to incrementally increase his speed.
* IDidntMeanToTurnYouOn - Numerous times, Train unknowingly causes Creed to be aroused when he kills. In the anime, he even gets turned on when Train smashes his sword with his orichalcum gun. Train even SITS on Creed with his legs spread , and belatedly realizes that Creed is practically having an orgasm over Train's awesomeness, and moaning "Oh Train, you are the best!" (In the English dub: "That's it... my Hartnet..." which is arguably even worse).
* IdiosyncraticEpisodeNaming
* IDontKnowMortalKombat - Train is lousy at video games - even first-person shooters and light gun games (the latter particularly perplexes him, as he notes the similarity between them and target practice).
* IfICantHaveYou - Creed eventually tells Train that, if Train is unable to "break away from that woman's curse" and join him, he will kill him.
* ImplausibleFencingPowers - As mentioned before, Kranz is a blind man who can cut bullets apart with a knife. The first appearance of Sephira's weapon, a stylized broadsword, involves her using the blade to juggle a glass of water without damaging the glass or spilling a drop as fencing practice.
* ImprobableAimingSkills - Train can shoot down bullets in midair with ease.
* ImprobableWeaponUser - Sven's attache case, which basically contains whatever he needs.
** Its also a SwissArmyWeapon with all sorts of useful gadgets.
** Several of the the Chronos Numbers also use some really ''odd'' weaponry, including a RazorFloss glove and some kind of bizarre rocket-powered flail. The winner would have to be Number X, Lin Xiao Li, who uses what can only be described as a weaponized ''blanket''. It has Orichalcum fibers woven into it to make it bulletproof and razor-edged... but it's still a blanket, and he still uses it as a weapon. Somehow.
* InLoveWithYourCarnage - Creed gets really aroused whenever he sees Train go berserk and kills. Uh, REALLY aroused.
* ItsPersonal: Train's reason for wanting to kill Creed. [[spoiler: He gets over it.]]
** Eventually Train turns out to want [[spoiler:Creed to redeem himself and "rebuild this world as a human."]] Creed actually pays attention to this, which could be seen as a baby step.
* JustInTime: Train does this a LOT when rescuing people. Quite a few times on purpose, as it is later revealed in a few instances that he had arrived earlier but wanted to wait for dramatic effect.
* KarmaHoudini: [[spoiler: Train allows [[BigBad Creed]] (who at least ends up in psychosis-induced a coma), [[TheDragon Shiki]], [[TheBrute Maro]], [[TheDarkChick Echidna]], [[EvilGenius The Doctor]], [[PyroManiac Kyoko]], and [[NobleDemon Charden]] to escape]] Whether getting the crap beaten out of them first and (in some cases at least) finding a new lease on life is enough of a punishment is left up to the reader.
** Whether or not it is personally satisfying, it fits with the tone of the manga, given that Train (and some others) sees 'himself' as a KarmaHoudini of sorts. He may be doing his best to repent his days as an assassin, but even he thinks he got off pretty lightly.
* TheKlutz: [[spoiler:Professor Tearju]], who also has elements of the LethalChef.
* KnifeNut: Kranz from the Chrono numbers wields a vibrating knife as his primary weapon.
* KnightTemplar: Chronos is an orginization of these.
* LadyOfWar (Chronos Number 1, Sephiria Arks. Quiet, dignified, wields a relatively small, ladylike weapon, and one of the deadliest people in the series.)
* {{Leitmotif}}- Train has one for whenever he makes a dramatic entrance. And it is [[CrowningMusicOfAwesome awesome]]
* LikeAnOldMarriedCouple: Eve points this out to Rinslet and Sven at one point in the anime, much to Rinslet's irritation (and Sven's pain).
* LittleMissBadass and LittleMissSnarker: These tropes ''are'' Eve.
* LoveAtFirstSight: Creed is revealed to have fallen for Train at first sight (as shown in a short excerpt in the manga, where the scene of their first meeting is shown). This also cements Creed's status as a masochist, considering that his first interaction with Train consists of Train glaring disdainfully at him and basically telling Creed to shove off because he's useless to him. And Creed, being Creed, ends up [[TooKinkyToTorture getting aroused by this]] and becomes Train's StalkerWithACrush.
* LoveDodecahedron: This trope happens to go hand in hand with the AllLoveIsUnrequited trope. It's incredible how intricate and complicated the character's romantic feelings (or lack thereof) for each other are.
* LoveMartyr: Echidna is this way for Creed. How she can put up with Creed's obsession with Train and insanity is a mystery.
** She [[spoiler:does end up getting him in the end, albeit as a nurse/mommy substitute.]]
* MagicBullets: Train ''never'' misses his target, or fails to do damage, except when his shooting is used as a [[TheWorfBarrage Worf Barrage]].
* MagicalEye - Sven's right eye, which can see up to 5 minutes into the future ([[spoiler:and eventually speed up his perception of motion]]). Comes with an EyepatchOfPower.
* MasterOfDisguise: Lin Shaolee can convincingly make himself look like Train, Creed and a number of other people. His disguises are so good that even when minimal, Train didn't recognize him as [[spoiler: [[PaperThinDisguise Glin]]]]
** A bit funny when you consider that the first time Train meets Lin, who was in a disguise that don't look like him at all, Train recognize him immediately, but when Lin disguised himself as [[spoiler:Glin]], [[PaperThinDisguise he looks like his normal self so much, but this time Train doesn't recognize him. Some kind of inverted effectiveness disguise is working here]].
** Nothing of the sort. Lin notes that he doesn't need a fancy disguise, since no one knows what he really looks like anyways.
* MeaningfulName: Saya - an alternate translation for the name is 'scabbard'.
* MrFanservice: Creed likes to wear chest-baring shirts a lot, and even has a long lingering pan of his body as he lounges naked in a bathtub with only strategically placed roses. Not to mention the shot of him getting OUT of the bath.
* MurderTheHypotenuse: Creed plays it a little too straight in his murder of [[spoiler: Saya]] (I've killed her, see, now you can join me!), and when Train still doesn't come around, he [[spoiler: attempts it on Train's [[HeterosexualLifePartners Heterosexual Life Partner]] Sven]].
* NamesToRunAwayFromReallyFast: Jenos '''Hazard''', Chronos' VII, who is depicted as a very dangerous fighter armed with RazorFloss.
** Although in French, "hasard" just means "fortune", which is consistent with his first name (spelled Janus in the French edition, as in the Latin deity) and makes it a regular MeaningfulName (... except, WhatDoYouMeanItsNotSymbolic ?)
** What about a guy who goes by XIII?
* {{Nanomachines}}: The most commonly used [[AppliedPhlebotinum Phlebotinum]] of the series. They can heal, turn body parts into weapons, mutate people into strange creatures, and in the final battle [[spoiler:turns Creed into an indestructible god-man]].
* NiceHat: Sven's. After it's destroyed, within a page he has it back (cited as an "emergency spare").
** And Charden's.
* NietzscheWannabe: Creed
* NobleDemon: Charden, the blood-controlling Apostle who realizes that he doesn't approve of Creed's methods. He's still determined to do the right thing for the world, but he has to do it alone. He also jettisons his sidekick Kyoko because he doesn't want her to get hurt.
* NoSenseOfHumor: Creed Diskenth
* NumerologicalMotif: the top operatives of Chronos are the Chrono Numbers. Train, the titular Black Cat, was XIII.
** Additionally Jenos Hazard VII can be considered very lucky. Not with the ladies, but professionally speaking.
** Not just numerological, but time-based as well, as in the hours on a clock. Befitting of a group called Chronos. XIII Is the wildcard.
* TheObiWan: Saya, [[spoiler:complete with ObiWanMoment]].
* OhCrap: Creed, when accidentaly hitting Train with [[spoiler: nanomachine "Lucifer"]] bullet. Again, Creed seeing Train's charging [[spoiler: Burst Railgun]].
* OlderSidekick - Sven, to Train.
* OlderThanTheyLook - Sven, who is comfortably within the CompetenceZone, ages from 28 to 30 over the course of the series. He looks a bit closer to mid 20s, but that doesn't stop him from getting called an old man more often than he'd like.
* TheOmniscientCouncilOfVagueness - Chronos.
* PartialTransformation
* PerpetualPoverty - Train, Sven, and Eve are almost always strapped for money (if it's not because they can't claim the bounty, it's because Train [[DestructiveSavior destroyed things]] or [[BigEater eats too much]]).
** And when they do actually score a large bounty, [[StatusQuoIsGod Train will often turn down all but around 20% or less of the reward money...]]
* PistolWhipping - Train's gun even has a cord on it to let him do this from a distance.
* PoliceAreUseless - The police in Sangeles City did not notice the completely conspicuously-dressed people that were the Apostles of the Stars. This got them killed.
* PosthumousCharacter : Manga-verse Saya and Lloyd, both only seen in flashbacks (or ghosts/hallucinations on Creed's part...)
** Train and Sven also feel the presence of their deceased friends at appropriate points, although it's left up in the air if it's their actual spirit or just their imaginations.
* PrettyInMink: The first episode shows a number of {{Socialite}}s wearing fur wraps.
* PsychoForHire: Subversion. Chronos Numbers Kranz and Baldorias aren’t actually for hire, being as they've worked for Chronos all their life, but they do seem to eh...[[AxCrazy enjoy their work]] [[JerkAss a little too much.]] Also [[{{Cloudcuckoolander}} Kyoko]] who signed up with Creed so she could [[PyroManiac burn things]], and [[InterplayOfSexAndViolence kiss people]]. At the same time.
* RazorFloss: Jenos' weapon Excelion uses this. He's capable of slicing stone pillars into rubble and defeating dozens of opponents, although he can also snatch people out of the air without harming them, or tying them up.
* TheReasonYouSuckSpeech: In the manga, Train delivers one at the end: [[spoiler: when Creed is in shock at his defeat, wondering why Train could follow Saya's way of life even though Creed and Train are NotSoDifferent, Train notes that Saya had just as terrible a life in her past as both Train and Creed. She just refused to use it as a FreudianExcuse and instead tried to make the world better in her own way, without destroying anything.]]
* ScarfofAsskicking: Train wears a red one in the last four episodes of the anime (episodes 21-24).
* ShapeshifterWeapon: Eve's modus operandi in combat. She starts out only able to turn her hands into blades on account of the lack of imagination that comes with her initial {{Tykebomb}} status, but as the series progresses she starts to branch out into other types of transformations, like turning her body into steel, growing wings, turning her hands into shields, and turning into a mermaid. Her ultimate technique turns her hair into a mass of monomolecular blades.
* ShowerScene - In episode 14, Train is seen having a shower at the end. When he comes out, he is [[http://static.tvtropes.org/pmwiki/pub/images/Topless_Train.jpg only wearing a towel]]
** Rinslet gets a shower scene as well in the tenth manga volume, with her bare butt quite visible, as if to reward readers for sticking so long.
* SingleTargetSexuality - Creed is "Train-sexual." Train could be a man, woman, cat, three-eyed Martian and Creed would still be hot for him.
* SoundtrackDissonance - At the end of the first episode, Train is having a flashback about when his parents died, to the tune of Konoyo no Uta (the song Saya sings).
* SpellMyNameWithAnS - Sven Vollfield/Borfield/etc, Sephiria Arks/Axe, Jenos/Janus, Sharden/Chalden/etc, Lin Shaolee/Xiao Li, Grin/Glin/Green...
* SproutingEars - Again, Train in more lighthearted moments.
* StalkerWithACrush - Creed is reeeaally interested in Train and refuses to accept that Train just ain't interested. If Train says no, Creed thinks he must be being influenced by someone evil. [[spoiler:Kyoko becomes a more humorous example after her HeelFaceTurn.]]
* StateSec: Chronos has got this one covered.
* {{Stripperiffic}} - A one-off nameless character that Charden and Kyoko run into. Kyoko asks her [[LampshadeHanging if she's cold, since she dresses so skimpy]]. (And then refers to her as "the girl that's cold all the time" before [[spoiler: burning her to death]].)
* SuckMyRose - Creed carries a rose many times, and sometimes even puts it in his wine (in the manga). This is exaggerated in the anime, where he even lies in a bath of roses.
* TeamDad - Sven
* TechnicalPacifist - Train, which is why he will occasionally throw his gun instead of firing it. Even when he does fire, it's usually something like a "freeze bullet" that doesn't kill but immobilizes.
** All the sweepers go to extreme lengths to avoid actually killing anyone, regardless of how much they deserve it. This is explained by a rule that says if anyone dies during the capture, they only get half the reward (except for the highest class of criminals, usually violent murderers).
*** Even some of the Chronos Numbers, who are assassins, avoid killing. Jenos manages to slice up and pile up a large number of attacking thugs without actually killing them, and Shaolee prefers to slice off hands or guns rather than actually kill (and he likes manipulating people bloodlessly even more).
**** ... though as mentioned earlier, Shaolee really comes across more as needlessly cruel and does end up destroying his targets (but they're actually [[CyberneticsWillEatYourSoul cyborgs...]] [[TheDarkSide and the transformation was voluntary]])
* TechnicolorEyes - Notable in that for the most part, Black Cat is pretty good about using realistic hair colors. Eye colors, however, not so much.
* TeenGenius - [[spoiler:Professor Tearju]] Graduated from university when she was 14. With a double Ph.D.
* TheyWereHoldingYouBack
* ThirteenIsUnlucky - Train has the number 13 etched on the side of his custom-made gun. He also has this number tattooed on his collarbone. His catchphrase? "I'm here to bring some bad luck."
* ThouShaltNotKill: Train practises this after the first few chapters.
* TokenMiniMoe - Eve
* TookALevelInBadass - Eve is a textbook example of how to do this the right way through character development. At the start of the series her shapeshifting powers are largely undeveloped and limited to turning her hands into blades, and Eve herself is an emotionless {{tykebomb}} taking orders from a scumbag weapons merchant. By the end of the manga she's [[TakingTheBullet taken a bullet]] and [[NormallyIWouldBeDeadNow lived to tell about it]], used {{Heroic Resolve}} on at least one occasion, [[ThrowingDowntheGauntlet thrown down a gauntlet or two]], and her developing imagination has shown her dozens of other ways to use her powers. She ends the series as the strongest of the main heroes aside from Train (...maybe) and arguably the most {{badass}}.
* TrademarkFavoriteFood - Train is pretty much a milk junkie.
* TriggerHappy - Train, although, being a [[TechnicalPacifist pacifist]], he's the non-lethal kind.
* {{Tsundere}} - Rinslet is reduced to this in the anime, rather than the kickass thief out for herself. Not to mention that she, instead of having dere moments for Train, has them for Sven or Jenos.
** Train himself is definitely one as well ( though most notably in the anime).
* {{Tykebomb}} - Eve [[spoiler: and little Train]]
* UnexplainedRecovery: After getting age regressed by nanomachines, Train has to seek out Dr. Tearju in the manga to help him get back to normal. In the anime, he sort of just goes back to normal after a while [[spoiler: because the writers apparently needed to save Tearju for the Eden arc.]]
* UnguidedLabTour: Rinslet sneaks into Tornero's lab to steal information and discovers human experiments that look like chimeras.
* {{Unobtainium}} - Each Chrono Number has a weapon made of indestructible Orichalcum. These weapons bear the Number of its user, and have [[WhatDoYouMeanItsNotSymbolic a mythological name]]. Train's gun is called "Hades".
* VillainousBreakdown: [[spoiler:Creed. The breakdown's so bad that in the end, he can't even move or talk, although both Echidna and Train imply that he can get over it]]. He does seem to improve a little just at the thought that somebody cares about him without his power.
* VillainsOutShopping: Kyoko does this a lot.
* WeCanRuleTogether: Creed spends the ''ENTIRE SERIES'' telling Train this. Train doesn't seem tempted.
* WhatBeautifulEyes: Train's cat-like, yellow eyes. Both Creed ''and'' Saya mention how beautiful they are.
* WhatIf: The anime works as a What If story to the manga in some ways, starting with "What If... Train had met Sven while still an assassin [[spoiler:and was sent to kill Eve?"]]
* WhenAllYouHaveIsAHammer: Durham's answer to a lot of things is to simply shoot them. [[YouHaveFailedMe It comes back to bite him]].
* WickedCultured: Creed is definitely one of the more "cultured" characters in the series.
** Lampshaded by the author in a side story where he's enjoying a glass of wine in rich surroundings... and goes bananas because of a cockroach.
* {{Yandere}}: Creed certainly goes crazy whenever anything has anything to do with Train. He loses all sense of rationale despite normally being a calm, ManipulativeBastard.
* YouCantFightFate - Sven may be able to see the immediate future, but he's never been able to actually change the outcome. Although [[BlessedWithSuck given the very limited timeframe he can actually see]], it's debatable whether it's because YouCantFightFate, or because it just happens too quickly for anyone to be able to do anything about it.
** Lloyd could originally see further in the future, but explicitly chose not to fight it in at least one instance... which is how Sven got his eye in the first place.
* YouGottaHaveBlueHair: Most hair colors in Black Cat are fine, as it's set explicitly not in Japan. Leon's and Jenos's dark green is probably just stylized black and Echinda was blonde before her Tao mutation, but Sven's green and Rinslet's purple just deny explanation.
** Also, Kyoko, who is explicitly stated as being from the in-universe equivalent of Japan ("Jipangu"), does have black hair and dark eyes.
** River's hair was inexplicably turned from blond to ''pink'' in the anime, though. And I think Leon's hair was light purple in the manga...
** The eye colors, however, are [[TechnicolorEyes considerably less realistic...]] (Orange, red, yellow, gold, pink, purple...)
* YouHaveFailedMe: Happens to various people like Durham [[spoiler: whom Creed killed because he left on his own, screwed up and vowed to kill Train]] and Gyanza [[spoiler:who wasted all his power until he died.]] Also happens in a much lesser way to Train during his Chronos days, when he was imprisoned for awhile because he [[spoiler:stopped killing his targets.]]
