Emotionless Girl - Television Tropes & Idioms

Staring contest!

"I'm sorry I can't be as high-strung and crazy as the rest of you."
- Mai, Avatar The Last Airbender

The enigmatic emotionless character. Sometimes the anchor in the midst of chaos; other times just quietly mysterious. Draws attention to herself simply by her non-reaction. Can be seen as purposeful, cool in a crisis, i.e., "she's all business." May also have some sort of secret special power.

Sometimes used by animators as the comic foil, especially in noisy, chaotic situations.

Not necessarily a fan of pure logic and reason like The Spock, as compassionate under the skin as the Tin Man, as wise and profound as Silent Bob, or as strong and badass as The Stoic.

In certain instances, may be an actual Robot Girl. See also The Quiet One, Strange Girl, and The Daria. Often contrasted with a more Hot Blooded partner to form a Red Oni Blue Oni pair.

An interesting twist on the Emotionless Girl is the Emotionally Repressed Girl. This girl feels the emotions but doesn't express them openly or vividly. These girls can draw the viewers into the scene by forcing one to pick up on her subtle cues - so that when the seemingly Emotionless Girl finally does smile, there's a tremendous amount of satisfaction.

They may suffer from Bad Dreams. Contrast Kuudere, who may initially appear emotionless but in fact has a cute inner side. Will often be the subject of Must Make Her Laugh.

Examples

Anime

Senri from +Anima fits this perfectly, even though he's a boy.
Axis Powers Hetalia: Emotionless Boy Hong Kong. Belarus is a female version, who mixes it with Yandere as well.
Chane Laforet from Baccano!, who actually is mute.
Kazuo Kiriyama from the Battle Royale manga is an Emotionless Boy. He was rendered incapable of emotion when he was brain-damaged at the age of six (since birth in the original novel), and is described in-story as a sociopath. Add to this his phenomenal analytical ability and intelligence and you've got a very tough match-up.
R. Dorothy Waynewright from The Big O. She's an actual Robot Girl. On at least one occasion, she expresses relief on never being programmed with emotions, although arguably she didn't need to be — she demonstrates disgust, loyalty, nostalgia, and numerous other emotions, just not at what a human would call full intensity.
- Never mind the irony of feeling relieved not to have emotions.
Nemu, Mayuri Kurotsuchi's Lieutenant in Bleach, is not just emotionless but seems to have no free will of her own. She exists almost as an extension of Kurotsuchi's will; no matter how horribly he treats her, she never reacts. Mad Scientist Kurotsuchi CREATED Nemu. His "daughter" is really just an Opposite Sex Clone.
Six year-old Rin Kaga of Bunny Drop appears as such at first. It is even used by members of her father's family as an excuse not to take her in. However, Rin is more of a Deconstruction given that she is only like this because of shyness and anxiety around people she does not know. Around other children and Daikichi, Rin is anything but emotionless.
Captain Tsubasa has two male versions: Carlos Santana and Stefan Levin. The first one becomes emotionless after a tragic childhood where he lost everything (from his adoptive parents to his friends), the second lost his emotions after his fiancée Karen tragically dies in his arms. Both start to gradually heal through the series, and Santana even gets to find his Missing Mom.
Fiore from Chrono Crusade, although it's hinted throughout the series that she may not be as emotionless as she claims—and her relationship with Joshua is a partial reason.
Anya from Code Geass. Maybe she was just traumatized from seeing Marianne killed in gory fashion and then getting marianne's consciousness put into her head against her will..
Yin, and others, from Darker Than Black - one plot point of the show is the existence of Dolls, humans brainwashed into (nearly) emotionless mediums that can be used as undetectable spies.
Saki Hanajima from Fruits Basket, and surprise! She does have special powers. Her little brother, Megumi, is also emotionless and can curse people.
- Ironically, both of them are actually familiar and regularly express the one emotion that causes most of these examples to come out of their shell: Love. Saki is extremely protective and (sometimes overly) friendly towards her best friend Tohru, and Megumi behaves similarly towards his sister. Saki's treatment, thus, ends up flip-flopped between Emotionless Girl and Yamato Nadeshiko depending entirely on who she's associating with at that particular moment. Just don't mess with Tohru. Ever.
  - But even when defending Tohru, she does so in a Creepy Monotone.
Vanilla from Galaxy Angel. Used in the anime to comic effect. In the games, her story arcs deal with her coming to terms with expressing emotion.
Feldt Grace from Gundam 00, though she later starts to become more emotional.
Kanna from Inu Yasha most certainly fits this trope, as she was created to be emotionless so that she would be undetectable by any trace of Demonic Energy or Scent. In fact, the translation of her name quite literally means 'void'.
- Though before she die her/ last emotion◊ pretty much tear jerker.
Toyama Sachi from Jubei-chan. In the dub, she is referred to as "the strange, emotionless girl" once.
Yuki Nagato from Suzumiya Haruhi, the girl from the pic above, is also the The Spock, The Stoic and the Badass Bookworm.
- Though as the series progresses, it is clear that (due to Character Development) in spite of her lack of apparent feeling, Yuki is a warm, caring and kind-hearted girl. It could be said that Yuki and Asakura are subversions of this trope (and by extension, Red Oni Blue Oni). Yuki appears emotionless and coldly logical, while her inner workings are clearly fighting in the other direction. Asakura is what could best be described as a Purity Sue on the outside, while she is the creepy, emotionless Knife Nut whose attempted murder of Kyon was actually a calculated act designed to reach a specific goal.
- Kuyou Suou, another alien interface, albeit from a different entity appears in the ninth novel. She appears to be a genuine Emotionless Girl.
Rei Ayanami from Neon Genesis Evangelion is frequently mistaken for being emotionless, but viewers who pay any actual attention to the show know that she's just repressed.
- As Rei's Expy in Dual!, D fits this until the final battle. She's actually frightened about showing emotion.
- Much like the "Spoke eyebrow", the subtle hint that Rei is actually having an emotional reaction is if she bothers to make eye contact with something, which she normally doesn't do.
Ruri from Martian Successor Nadesico is one, arguably. Though she's far cry from being actually emotionless - just emotionally repressed, and sometimes not even that - her voice never seems to reflect her emotions, making her always sound like she just doesn't care. This is a big part of why she used to be the Trope Namer for the Little Miss Snarker.
Mai from Kanon.
Karin's little sister, Anju, in Karin.
Another Anju — the maid Anju Rika, in Magikano.
Sai Jounouchi from Kidou Tenshi Angelic Layer. The anime made her emotionally repressed and gave her a Dead Little Sister, the manga doesn't explore her character enough.
Kirika from Noir spends most of the anime as just this.
- Objection! Normally she just has hard time expressing her emotions, but is clearly a big ball of angst. She becomes a true Emotionless Girl near the end, when her "real" personality takes over, but the her emotional side eventually comes out thriumphant (and despite of being "false", is clearly morally superior of the two).
Most of the eponymous warriors in Claymore, though that makes them more like The Stoic.
Angel Densetsu's expy to Claymore (Ikuno/Claire) is a Deadpan Snarker too.
Ritsuko from Kujibiki Unbalance hides secret feelings for Chihiro behind an emotionless exterior.
In Onegai Teacher and its sequel Onegai Twins, (aka Please Teacher! and Please Twins!) extreme emotion can induce the coma-like "standstill" state. Ichigo Morino, who has experienced this, forces herself to be calm, but the writers sorta didn't get it right: she gives the same lines anyone else might give, but with a HAL-like delivery. She sports Mind Control Eyes but makes otherwise normal facial expressions. In other words, no more the Emotionless Girl than anyone else, but acting like one.
Lumiere from Kiddy Grade is both this and The Spock.
- This troper disagrees; Lumiere was more calm and composed than expressionless (remember "girls should be elegant"!), so it's more of a Yamato Nadeshiko.
A very very rare male version of this trope: Mytho from Princess Tutu, who is literally emotionless thanks to a spell that shattered his heart.
Nozomu from Kanokon. Her gluttony notwithstanding, she is a partial subversion. While she acts emotionless, with a consistent monotone voice and blank expression, she displays an unexplained attraction to the hero. And she is able to easily keep up with Chizuru — who is just shy of being an outright anthropomorphic personification of lust — in flirting and "dirty" tricks. In some of the DVD-only, nudity filled filler episodes she openly talks about lusting after the main character and being in love with him. Due to the length of the anime, and it skipping a book or three of the original series, her character development is more or less completely nill, as well.
- She even has no qualms essentially pimping the main male lead out to Chizuru in order to try and "fix" her stolen magic / breasts, and in the Gecko Ending of the anime it's Nozomu who suggests the Tenchi Solution.
Akira Takano from School Rumble.
- Male example: Oddball Karasuma. Yeah. He had been repressing his feelings from the very beginning in an attempt to distance himself from everyone. When he finally snaps very late in the manga, his bouts of emotion are so expressive, he becomes almost unrecognizable.
Now And Then Here And There has Lala-ru, although she does start to emote more as the story progresses.
Lutecia in Magical Girl Lyrical Nanoha StrikerS. Likely a result of Jail's experiments and/or of growing up without her mother. She becomes more emotional by ViVid.
Lila from Najica Blitz Tactics showcases many characteristics of this trope, being an artificial human, although she can fake emotions to some degree if needed to achieve a certain goal (like seducing men). Later in the series she starts to genuinely warm up toward the protagonist though.
Sai, of Naruto fame, may not be a girl, but he certainly belongs here.
Alissa Southerncross from Keroro Gunsou.
Koihime Musou has Ryoufu, a Gender Flipped version of Lu Bu (yes, ''that'' Lu Bu) who — while being Made Of Iron and flinging other "badass generals turned Moe girls" around without breaking a sweat — is also so unexpressive that she maintains a total deadpan while Glomping a minister who took in her and her canine companions.
- From another Romance Of The Three Kingdoms gender flip, Ikki Tousen, there's Zhuge Liang's reincarnation Shokatsuryou Koumei who mixes this with Little Miss Snarker and Creepy Child...
Akira Okochi in Mahou Sensei Negima has her emotions, but is usually so quiet, her Day In The Limelight chapter was told entirely without dialogue.
- Asuna was also emotionless in the backtory. She was still emotionless upon arrival, but ten years of being bugged by Ayaka taught her emotions, albeit mostly emotions regarding irritation.
- Yue also fits this for the first section of the manga. She hides her emotion so well that her total breakdown upon finally accepting that she has a crush on Negi seems even more shocking.
  - She's more cool-minded rather than emotionless, since she's philosophical girl usually ruled by reason over emotion.
- With a possible exception for the ending fight in the first "season", Zazie Rainyday is completely deadpan. It's worth noting that even in the retelling of Negima!?, nearly all of her lines are puns or wordplay, and naturally are all spoken in a monotone.
- Chachamaru is a justified Emotionless Girl, being a robot. Even so, she's a very caring person whose main fault is My Master Right Or Wrong.
Shizuku, the Token Loli Cute Monster Girl from Omamori Himari.
Otome from Koi Koi 7. It probably comes from being the oldest of the group, but stuck at a young age, since she was the first to become a cyborg.
Ayuki of Kashimashi Girl Meets Girl seems to be one of these in the anime. However, in the manga, she just seems quiet and calm. However, even then she nevers shows much emotion other then some casual comedy moments. Except in a later chapter, where she cries and screams at Hitoshi when she learns that Hazumu will die in 29 days. This only fuels the theory that she is in love with Hazumu, which was never really hinted at in the anime (instead, it was hinted she likes Tomari)
Anthy Himemiya from Revolutionary Girl Utena is a variant on the Emotionally Repressed Girl, in that she is effectively anaesthetized by the circumstances of her... very complicated connection to her brother.
Tomoe Yukishiro from Rurouni Kenshin plays this for tragedy, since she couldn't show her fiancé Akira how happy she was when they got engaged, so he thought he wasn't good enough for her and went to search for his fortune to Kyoto... where he got killed.
Zefiris from Scrapped Princess. Also a Robot Girl - kind of.
Momo from Shinigami no Ballad is a subversion. She appears emotionless, but allegedly feels more strongly than normal humans do. The other shinigami plays this straight though.
Primula in SHUFFLE! is an excellent example of the repressed type.
Sara Werec of Soukou No Strain is an example of an Emotionless Girl main character.
Latune Subbota from Super Robot Wars: Original Generation. Then she gets a crush on the Hot Blooded Ascended Super Robot Fanboy, and clears all that right up.
Yami from To Love Ru, although she has shown the barest hint of emotions other than "I hate ecchi people" on occasion.
Michiru from Uta Kata.
Echo from Pandora Hearts although later on in the manga she changes to more of aKuudere
Laila from Venus Versus Virus, in contrast with her somewhat livelier twin sister, Lola.
Tabitha of Zero No Tsukaima, of the repressed variety.
Miyabi "Professor" Oomichi of GA Geijutsuka Art Design Class.
Marie Kagura of Tona Gura. Subverted somewhat in that this state hides a desire that her older brother Yuuji revert to his pre-puberty self and pay attention only to her.
Aki Izayoi from Yu-Gi-Oh! 5D's.
A Devil In Plain Sight from a manga I can't remember is basically Mandy (specifically Bleedman's teen version). She may have been a terminally Ill Girl but thanks to a love-struck Grim Reaper she will rule the world with an iron fist.

Comic Books

X-Men has Sage, a mutant whose brain works much like a computer, and as such, approaches Rei Ayanami level emotionlessness at times, though occasionally shifting to The Stoic level when really, really worked up. (Naturally, she's such an expert at Perp Sweating that her gaze alone accomplishes what Wolverine's famed "claw on either side of neck; dare me to pop the middle?" approach cannot.) Surprisingly, "computer brain" simply describes her brain works. Despite the functions of her mind often being described in computer terms, it, and the rest of her, are a hundred percent organic.
- She can still say her name in gigantic, colorful letters, though. (Is there a trope for that?)
Raven from Teen Titans. This based out of necessity because if she ever let her emotions go, her demonic father, Trigon would seize control of her and take over Earth's dimension. Her learning to accept and express emotions after the defeat of her father is a major piece of Character Development.

Film

Wednesday forcing a smile in Addams Family Values evokes horror in onlookers.
Lydia in Beetlejuice. In the animated series, she becomes a Perky Goth.
Subverted and lampshaded mercilessly in the Rocky And Bullwinkle movie with agent Karen Sympathy. She tries relentlessly to be an Emotionless Girl Scully, but she's just too sentimental.
Miette starts off like this in The City Of Lost Children.
Margot(Gwyneth Paltrow) in The Royal Tenenbaums

Literature

Susan Calvin from Isaac Asimov's many robot short stories.
Susan Sto Helit of Soul Music, Hogfather and Thief Of Time shows no outward emotion on hearing of the deaths of her parents, and otherwise fits the "cool in a crisis" model. She does occasionally get angry. Don't get in her way at this point.
- Adora Belle Dearheart in the "Moist Von Lipwig" novels also comes across as emotionless, when she's actually repressing a mountain of rage.
  - Alternatively, she comes across as a woman burying her issues under a mountain of bitter sarcasm.
In the Star Wars Expanded Universe novels, Winter Celchu (an aide and childhood friend of Leia's), an Intelligence agent with a holographic memory, has lost her composure perhaps once in the entirety of her appearances—when she thought her boyfriend had been killed and his fellow pilots didn't seem to care (because, of course, he was still alive).
Kahlan of The Sword Of Truth has this as a public persona: A voice to freeze water. Another example is Nicci, who is more in the idea of an impassive Dark Magical Girl hardened by a rather unpleasant life until she no longer cares about life anymore. Richard does manage to get through to her in the sixth book, though, shortly before she does a High Heel Face Turn.
Actually subverted in The Dresden Files. Ivy appears to be totally emotionless for quite a while after we meet her, but it turns out that this is actually one of the Archive's defense mechanisms. Ivy herself is lonely and has to cope with the fact that she has almost no personal identity; even her name is just a nickname Harry gave her. She's also cursed with the Archive's perfect recall, so she knows exactly how her mother felt about her. (Hint: It wasn't real positive)

Live Action TV

Star Trek sports a couple examples, such as:
- Seven of Nine from Voyager is a former Borg drone, so underplays emotions while focusing on efficiently completing tasks. However, she does annoyance really well.
- T'Pol from Enterprise is a Vulcan whose frustration with humans isn't veiled as well as it could be, but otherwise fits this trope.
- T'Pring and T'Pau from the Star Trek The Original Series episode "Amok Time".
- The first officer of Captain Pike, known only as Number One, was one of these.
Cameron, the female Terminator of The Sarah Connor Chronicles fits this quite accurately, though she is quite capable of simulating human emotions when she needs to. The rather sudden shift from emotionless blankness to a laughing, smiling teenage girl is....creepy.
- Of course, some of us have a reaction other than fear.
- Cameron's creepy stoicism gets played brilliantly in the premiere for the second season, when John is trying to remove her processor chip after it gets damaged and she goes berserk. She slowly switches from an emotionless, implacable killer to begging and pleading with John to not remove the chip, even going as far as to cry out that she loves him. The simulated emotion is disturbingly real, and even more so because the audience and John know it's simulated yet real.
  - According to Summer Glau, who plays Cameron, that might not have been simulated...
- This is further pronounced in the same season's eighth episode. Before Cameron enters John's room to discourage him from seeing Riley, she removes her jacket. She then lies on his bed next to him. The audience and John know that neither of these actions is casual, but a calculated decision by Cameron's internal logic. It is this knowledge that creates the tension in the ensuing exchange.
- Prior to this, there are a very few but very deliberate moments where Cameron shows inexplicable emotion - for example, when she hits Charley with a Death Glare for calling her a "very scary robot" in "Dungeons & Dragons", and a momentary tightening of her lips and nervous flicker of her eyes in "Vick's Chip" when John is removing her processor.
- Then it gets completely inverted in "Allison from Palmdale," where Cameron adopts the personality and memories of Allison, a girl her personality was based around. Seeing Cameron suddenly acting like a normal person, showing honest emotions, just amplifies the creepy factor.
Aeryn Sun of Far Scape isn't quite emotionless, but she rarely lets her emotions show and never lets them control her... except in one instance when an outside force actually took that self-control from her, which Chiana noticed when Aeryn freaked out.
The Actives in Dollhouse, when in their wiped state. Although they seem happy in a non-thinking way most of the time.
- Although this is deliberately encouraged by keeping them in a calm and peaceful place. If exposed to more dramatic stimulus they gain emotions quite quickly - terrified and freaked out.

Manhwa

Vera Linus, in the manhwa Veritas, generally shows no emotion except when dealing with something that has to do with Lightning Tiger, the guy who taught her the meaning of "fear".

Video Games

A plot point in the Darkstalkers series of fighting games. Donovan, a half-vampire monk meets Anita, a young girl who is also a half-vampire, who has lost the ability to feel emotions. He decides to try to slay the world's supply of monsters to cure her. He succeeds in restoring her emotions and humanity, but becomes a full vampire himself. This leads to a climactic flash forward cliffhanger showdown between her as the messiah of the human race and him as her main opposition. Especially notable because the creators of the series were sometimes criticized in interviews for using this trope, which was in its peak at the time.
Phoenix Wright Ace Attorney had Lana Skye, who had shut herself off to the outside world. Her control cracks when it appears her sister Ema is being accused of murder; she throws herself on the witness stand in a desperate panic. At the very end, when everything is settled and she finally smiles, several of this wiki's editors teared up.
- Vera Misham in Apollo Justice is of the repressed type. She never changes her facial expression, instead drawing smilies on a notebook she always has. In the good ending, she gives a proper smile at last.
Presea Combatir of Tales Of Symphonia was, among other side-effects, robbed of her emotions when implanted with an Exsphere without a Key Crest. She became so robotically narrow-minded that she didn't even notice her father had died in his bed years ago, though his body lay there decaying the whole time. She gets better when she joins the heroes, who give her a Key Crest, but then she has to deal with the pain of everything that's happened while she was like that.
In Suikoden V, which has Loads And Loads Of Characters (One Hundred And Eight, to be precise), Sagiri nonetheless manages to stand out due to this trope. Rather than having a perfectly straight face, her expression is frozen in a permanent creepy smile, no matter how she feels. Combined with the way she speaks, she comes across as rather spooky, even BEFORE you learn her backstory: She's a former member of the Nether Gate, a clan of fanatical assassins who don't recruit new members - they raise them. Trained from infancy to be an assassin, she was taught to put on a childish, innocent smile to help her approach her unwitting targets... even though she's a grown woman now, and even though she escaped from the cult more than 8 years ago, her face remains set in that same smile.
Ashley from the Wario Ware series. The most emotion she shows outside of her theme tune is a tiny smile at successfully turning a plant into a giant monster.
Amoretta from Grim Grimoire, a recently made homunculus with an angel for a soul. She has emotions, but she's quiet, composed, and probably very depressed by the emptiness of her existence up to that point, so it's understandable that she's less lively than the ghosts who show up.
Latooni Subota from Super Robot Wars: Original Generation starts out like this due to her Break The Cutie past.
- Alpha 3 feature male variant as Ace Gozzo whose consider himself as machine. When he's dying and taunt if he finally feel anything? Ace ask back why he has to feel anything? He fail his purpose and his life function going to cease soon, nothing wrong with that.
Pandora from Mega Man ZX: She's in every way opposite to her berserker comrade, Prometheus.
Marisa from Fire Emblem: The Sacred Stones is an emotionally repressed version. She at first seems to be a stoic, emotionless Blood Knight. Turns out she just doesn't know how to act around people. She opens up to whoever you pair her off with in support conversations.
- Sue of Fire Emblem: The Binding Blade also fits the trope perfectly. Seeing as she's the daughter of The Stoic nomad Rath from Fire Emblem, this should come as no surprise.
- And it's not only Sue there. Idoun the Dark Dragon and Thite the Pegasus Knight also count. The first simply doesn't know what emotions are like, the second is the emotionally repressed type with some dashes of Defrosting Ice Queen.
- Don't forget Limstella, the Dark Action Girl from Fire Emblem. Though to be fair, she can also be seen as a sort-of Robot Girl, since she's one of the morphs created by Nergal.
  - Sonia of the same series could be seen as a subversion, instead being an "emotionless" doll who believes herself to be a perfect human. Limstella puts and end to such illusions, however.
In Grandia II, Tio is an Automata, a humanoid robot built to fight in ancient wars. After the group defeats her and removes the claws of Valmar (read: Devil), Mareg takes the emotionless machine under his wing, believing that she does in fact have emotions. In the end it turns out he was right, but she only really starts to display these after Mareg dies saving the group .
Hisui from Tsukihime seems to follow this trope at first, though it becomes apparent fairly quickly that she just suppresses her emotions very well. The real emotionless girl is actually the ever-smiling Kohaku.
Shanoa in Castlevania: Order of Ecclesia. Justified in that her emotions (and memories) were blown away at the beginning of the game. In fact, when told by a villager that she should smile more often...
Shanoa: "I do not smile."
Somewhere in between this and a fully fledged Robot Girl is Aki Zeta-Five, leader of the Cybernetic Consciousness in the expansion pack to Sid Meiers Alpha Centauri, who would pretty much count as a Nagato expy if the game wasn't 8 years older. She's fully human, but possessed by an artificial intelligence like the rest of her faction.
Princess Katrina of Wild ARMs XF. Although she's said to only not understand the concept of fear, she doesn't seem to feel much in the way of anything else, either.
Vasilios Cosmos(A guy) of Space Colony, withdrawn and doen't consider himself human.

Webcomics

Antimony from Gunnerkrigg Court is both stoic due to a recent tragedy and unflappable in the face of weirdness due to a very unusual childhood. She soon begins opening up to her best friend, but her unnervingly emotionless demeanor shows no sign of abating.
- Recent events suggest that the appearance of emotions on Antimony's face is directly related to her friendship with Kat. Because she gets ''really creepy'' when Kat is in trouble.
- Then there's Jones, who is even more of a blank slate. Whether she's expositing, flirting, intentionally ticking her student off, or even affirming that something was "hilarious", her expression does not change. Antimony herself has speculated that Jones might be a robot masquerading as a human.
For an example of an Emotionless Girl who doesn't overlap with the Shrinking Violet in romantic situations, see the 'Su Cool' LovSit story from the Tsunami Channel. Saki dearly loves the protagonist, but doesn't see why being embarrassed about it - or indeed, why calmly confessing in the middle of the classroom when everyone is having lunch - is likely to give Kei a heart attack.
Sara Amraphel from Errant Story, often lampshaded.
- And made disturbing in a recent sequence where for the purposes of subterfuge, she assumes an appearance and attitude that are very OOC.
Ditto for Wanda Firebaugh from Erfworld, who also lampshades her status.
Wanda: "I don't laugh."

Web Original

Alysia Morales from Arcana Magi, must remain emotionless or she will suffer physically.

Western Animation

Raven from Teen Titans (emotionally repressed out of necessity more than choice). She becomes more and more open as the series progresses.
- Though Raven can actually be intensely emotional- you do not want to see her angry. She needs to stay repressed in order to avoid losing control of her powers and/or unleashing her Superpowered Evil Side.
Mai◊ from Avatar The Last Airbender, who finds everything in life boring and "unbearably bleak"... everything except Prince Zuko.
Mandy in The Grim Adventures Of Billy And Mandy seems to have only three major emotions: indifference, disgust, and anger. She's only smiled twice in the entire series: in "A Dumb Wish", she gave a sinister smirk after accidentally wishing everyone on the planet would "go away", and in "My Fair Mandy", her attempt at a cheerful smile ended up destroying the universe.
- Giving a look of genuine sadness is even rarer; she's only done it once.
- But what about the pilot? She smiles there too.
- She's also shown shock and confusion, but that's understandable given the kind of people/things she hangs out with.
A minor Freakazoid villain, aptly named Deadpan.

Other

Pathologist Madeline Frost in Shadow Unit is the adult version of this trope; no one knows if she's autistic, sociopathic, deeply PTSD, or what, but the hospital where she works has a standing rule about letting her talk to actual living people. (Another character calls her "Cthulhu's Dream Date.")
