The Diclonii from Elfen Lied are masters of this, especially Lucy. The anime opens with her calmly walking through a high-security military unit, stark naked but for a large metal helmet, gently humming to herself whilst hideously ripping apart and mutilating dozens of soldiers.
In the Umi-Bozu arc of Mononoke, each of the characters in turn are shown illusions of their worst fears. After screaming, crying, collapsing and a character throwing up over the edge of the ship, it's the Medicine Seller's turn... and we're treated to a scene of him dissolving into nothingness. Outside of staring at his hands as they disappear, he has no reaction, but quietly closes his eyes and waits for it to finish.
The Medicine Seller actually does this quite a bit- given the things he dedicates his life to hunting are eldritch monsters and people are occasionally slaughtered graphically right in front of him, he has very little emotion to offer. Comparing the earlier example to his common behavior suggests he's not as unaffected as he seems- after the illusion ends, we're treated to a camera shot that lingers on his tightly-clenched hands.
Many of the eponymous warriors in Claymore, but especially Teresa of the Faint Smile, who is named for her habitual demonstration of the trope. She never gets angry and keeps her slight, Mona-Lisa smile even when ripping anAwakened Being'sarm off.
Priscilla's bored facial expression barely changes, even while she's killing Noel and Sophia and ripping off Ilene's arm, or single-handedly wasting Duff, Riful, Alicia and Beth. Emphasised even more in the anime, where she's voiced by the soft-spoken Aya Hisakawa.
Naruto has a group of characters raised on Tranquil Fury (ANBU), but Sai seems to be a special exception that falls into this.
The Fifth Mizukage appears to maintain a smile at all times, even when threatening to kill her bodyguard because she thinks he called her "old" (he didn't by the way).
Grove from Vampire Hunter D: Bloodlust, when he does that spirit attack thing. In his case, it can be justified: When not in his spirit form, Grove is immensely weak and bedridden; using the power nearly kills him every time, but he's free from his crippled body while it's active.
Yu Narukami in Persona 4: The Animation doesn't let anything get to him, in contrast to his more emotional partners. For example, when Teddie bites him through the TV screen in episode 3, he remarks how the pain makes him want to cry, even though he doesn't look to be in any lasting pain. His friends note this as well.
Ultimo from the manga of the same name, is a robot boy that embodies good and is always smiling. Even as he tells he is threatening his mortal enemy, ripping off one of his arms or indirectly killing nearby civilians during their fights, the smile never leaves.
From Code Geass, I give you Schniezel. Seemingly a kindly, reasonable fellow, greatly different from his siblings, he maintains a calm, serene demeanor throughout the entire series. He continues to have this serene manner even while ordering the deaths of millions, announcing to his sister his plans for global domination, and gunning that sister down when she tried to stop him from nuking every major city on the planet, killing billions. What's that about reasonable again?
Rolo fits this trope, as well. In one sequence, he greeted some childhood friends with a warm smile before slaughtering them mercilessly.
Ryoko Asakura in Suzumiya Haruhi No Yuutsu has the unnerving habit of still being the sweetest, nicest girl you've ever met, while attempting to slice you up with a knife. She was also unusually cheerful afterwards, smiling as she politely delivers a stern but calm warning to Kyon while her body was being disintegrated.
Itsuki as well, often creeping out Kyon due to his constant smile capable of resisting the possibility of an "End of the World" Special.
The Lord of Nightmares from Slayers Next embodies this trope, dishing out apocalyptic destruction while never once raising her voice above an emotionless monotone.
Nurse Takano Miyo from Higurashi no Naku Koro ni often talks in a stoned calm, friendly tone about horrible ritualistic murders. Considering that most of the rest of the cast tends to go psychotically Ax-Crazy, her nonchalant attitude sticks out.
And in some scenes of the Trigun Maximum manga, Knives butchers entire communities without any apparent emotion.
Sosuke Aizen from Bleach is the embodiment of this trope. It helps that to all appearances, his belief that he has nothing to worry about is entirely justified. It makes his loss of composure at the end of Deicide all the more stark as a result.
Retsu Unohana definitely fits this trope real well as she always smiles even when she's threatening you.
And Gin is always smiling.
Mizuiro is this when he confronts Aizen. The others are panicking around him. Instead, he simply begins experimenting with molotov cocktails and empty bottles with almost clinical detachment. He's more fascinated than afraid. His companions even point out how scary a person he is.
Tsukishima personifies this trope. He's screwed up Ichigo's friends and family and not only has he made them happy about it, but his polite, gentle manner actually creates the impression Ichigo is being completely unreasonable to be horrified by it.
We'd be lying if we didn't count Reborn in this too.
Several characters in Kara no Kyoukai show this, including the protagonist.
Worth noting is that the protagonist is this while holding a knife to the throat of her love interest, making this easily one of the most chilling moments on this page.
"Yet Shiki only continues to stare, unperturbed and placid. Red butterflies take flight from the wound, and descend lightly on Shiki's face, and on her ghostly kimono. Her blood-soaked lips twist into a shape...is it of fear, or of pleasure? Is she Shiki or SHIKI? I try to say something, but my voice stops, and I fall to the ground just because of the effort of trying to talk. I vomit, my stomach retching out all its contents, all the bile. I wish it retched out this memory as well, but no such luck. I vomit so hard I start to cry. But that doesn’t make me feel any more relieved. The overwhelming smell of the blood is so rich it drowns my brain. And finally, Shiki notices me. She turns her head to look at me, and I see now that the twist on her lips earlier was a smile, a kind of warm, motherly smile that is so at odds with the scene that it makes me shiver."
Anyone with the Will of D in the series always has a wide smile on their faces when faced with death. Gol D. Roger, Jaguar D. Saul and Portgas D. Ace had these smiles before they died, so did Luffy during the Loguetown arc when Buggy was about to execute him.
And one short battle involved Miyu against a Fetish Fuel clad schoolgirl Shinma with a flute who sported a similar grin.
Hakkai in Saiyuki is like this most of the time, utterly calm with a cheerful smile in battle and all other situations.
Mahou Sensei Negima!: One of Evangeline A.K. McDowell's crowning moments of awesome during the Kyoto Arc involved this. Give that girl her powers back for a little while and she'll freeze the world with the snap of her fingers and a smile on her face.
The lead Negi Springfield does this during his Unstoppable Rage against Wilhelm.
Seeing Fate Averruncus display anything other than that look of utter calm on his face is so rare as to be unheard of. Even when he's caught completely off-guard (does not happen often) or is losing a fight (happens even less often), his face betrays only the slightest hint of surprise or annoyance.
Balalaika even more so. Nothing says "I love my job" like grinning while snapping a Yakuza leader's neck, stopping to engage in a philosophic debate about the nature of the human condition with a would-be assassin whom she has just had shot or politely apologizing to Lagoon Company for any inconvenience they may have experienced during their last mission which ends with some unlucky bastard's apartment exploding.
What about Sawyer the Cleaner, who smiles cheerfully when she's gotten across that the smell that people were complaining about was the ooze from some bodies that decomposed badly before she was called in while everybody else is losing their lunch? Or Claude "Torch" Weaver, who wields a flamethrower and casually talks about how he burned his wife to death in five minutes,, or Shenhua, who can calmly carry on a conversation with a woman she's trying to kill?
Mr. Tick Jefferson from Baccano!! is genuinely happy so long as he gets to use his scissors to cut something. This "something" can be anything from hair, to paper, to human flesh.
Ladd's girlfriend Lua always has a perpetually vacant smile on her face, despite her lover's frequent promises to murder her.
Elmer's been through a lot and is a crowning example of this trope.
Shiro from Deadman Wonderland. She's shown completely ripping apart a bunch of guards, and smiling an extremely childish and happy smile.
Takeru (TK) has a touch of this in Digimon Adventure 02. Normally his reaction to seeing Digimon attacked or manipulated by evil is outright anger and fury (a result of the childhood trauma of watching his own Digimon die), but in his confrontation with the Digimon Kaiser, he suddenly gains a strange Dissonant Serenity and calm smile, while catching a whip in his bare hand and turning Crusader From Hell on everyone.
Kirika from Noir: from beginning to end, she never displays anything other than calm concentration while killing hundreds of people.
Altena also qualifies, and her creepy-ass village of Noir worshippers/sacrificial lambs that suddenly pull out guns and start killing elite members of the Soldats could also qualify.
Shou Kano in Kenichi: The Mightiest Disciple has a tendency to occasionally laugh cheerfully and apparently without malice while utterly destroying his opponents. Generally these are the fights that don't really have any personal meaning to him: other fights reveal something more along the lines of a Slasher Smile or at least a businesslike attitude.
Later on, we're introduced to one of the assistant instructors of Diego "Laughing Fist" Carlos, the Meatman, a rather large warrior who was charged with insuring that a bomb on the ship that several of the characters are riding goes off. When asked what he thinks will happen to HIM when the bomb goes off (by the characters who were trying to disarm it and therefore have to get past him first), he responds that he'll "calmly defeat" them and then run away before the bomb blows up.
In "Samurai Deeper Kyo", Kyo scares lots of people with his bloodlust in battle, but he is later repossessed by Kyoshiro, who scares people even more as he calmly slaughters elite mooks without showing any intensity in his expression.
Kasumi Tendo tends towards this in Ranma ½ as the varying antics, feuds and outright wars brought on by Ranma's various fiancees and insecurities take their toll on the Tendo household she never, ever seems to break a sweat or be anything but utterly sweet and smiling (occasionally looking worried when something truly disastrous occurs).
Carol of Project ARMS is a cute little girl with the power to break and twist things with a thought. When she fights Ryo, she happily sets about breaking every bone in his body while laughing. "Yay!" Keith White would also count, when he gently hugs Alice while she cries to him about how she is under so much pressure and just wants to be free for once. He kindly tells her that it's clear that he needs to change how she and the other children are being treated - before signaling for the kids to be shot.
In Full Metal Panic!, this was a defining trait of Sousuke's beautiful mother's death. When she was falling to her death, her face never showed a hint of terror or despair, and she calmly accepted her fate. Kalinin recalls from that instance that she was "surreally beautiful." Interestingly enough, this trait was apparently inherited by her son. As numerous instances afterwards, Sousuke has been described in very similar terms as being "surreally beautiful" the way he calmly massacres people.
D.Gray-Man mostly goes in for straightforward Slasher Smiles, so the exceptions tend to stick out. Such as in Chapter 182, when Allen accidentally wakes up the Fourteenth Noah inside himself.The Messiah should not smile like this when he's impaled on a sword and has a terrifyingly powerful monster less than a foot from his face. His expression barely changes even when Kanda almost stabs him in the head.
While granting that like his other murders, it's kind of unclear whether or not it was intentional, the Claw in GUN×SWORD exhibits this strongly in a scene where he deals with a mutinous subordinate. Personality-wise, the Claw is an affable Friend to All Living Things. So, he offers the subordinate a handshake (cue him squeezing the guy's hand hard enough to crack bone). Then, the Claw says that if the guy doesn't want a handshake, how about a hug. Not only is the hug also hard enough that you hear bones breaking, but when the Claw strokes the guy's back with his clawed hand, it's implied (but not shown) that he is ripping open his flesh. Throughout this horrible scene, the Claw is speaking in a gentle voice.
Russia from Axis Powers Hetalia. He acts rather childish and sweet, even when saying something threatening or disturbing.
Yoshii Kazuho from Texhnolyze always has a calm, pleasant smile on his face, even as he goes around shooting people and blowing them up with bombs.
"My smile becomes more beautiful the angrier I get."
Hosaka of Goshuushou-sama Ninomiya-kun. He always wears a calm smile and speaks in a polite manner even as he throws Shinobu out of a helicopter and curb stomps Shungo with the intent to kill him in the last episode.
The climax of the Kyoto arc in Yami No Matsuei (Descendants of Darkness): Tsuzuki has just stabbed Muraki, and called out Touda to burn down the lab. As the place burns and breaks down, he sits there numbly, doing nothing. It takes Hisoka to get him to even consider not staying there to die.
Contractors of Darker Than Black frequently kill in gruesome ways with little emotion and no remorse.
While not the one perpetrating the violence, as seen here◊, Oora of Sayonara, Zetsubou-Sensei is such a massive space cadet that she can calmly sit down in the aftermath of one of Chiri's rampages and never drops her permanent vacant smile.
Kyubey of Puella Magi Madoka Magica keeps his FrozenCat Smile and friendly voice, no matter what horrors are going on around him. Justified because he's a member of an alien race which is unable to feel any emotions (the ones that do are considered mentally ill).
Natives of the various Countries Of Hats in Kino's Journey often act this way. And then there's Kino herself, who remains eerily calm in the face of things that would send the average person screaming and running in the other direction. Probably because she's seen worse.
The original Ion from the Tales of the Abyss manga gaiden based on him. He almost always has a calm, friendly smile on his face even when he's killing one of his Replicas or talking about how the world is trash.
There's a sequence early on in Death Note where LightYagami sets up criminals to die throughout the day. The animation contrasts scenes of prison inmates collapsing and dying of heart attacks, along with the general panic and confusion of the guards and the other inmates, with scenes of Light going about his normal routine, like casually walking through a shaft of sunlight on his way to school, cheerfully playing a game during gym class, and opening a bag of potato chips at lunch. The effect is magnificently creepy.
This becomes a critical fact at one point. While Light is being monitored by cameras from almost every angle, he still manages to write names on a hidden scrap of the Death Note without so much as batting an eyebrow. Even L remarks that Kira has already elevated himself to the level of God if he can knowingly kill people without the slightest change in expression.
Medaka Box: Both Kumagawa and Zenkichi are the Trope Codifiers; Kumagawa brings a creepy edge to it, while Zenkichi is much more sincere.
Shin demonstrates this in the Area 88 OVA. When confronted by three Paris thugs, Shin just smiles. He remains calm as he snatches a knife from one of the thugs and hurls it into a robber's shoulder. The thugs are completely unnerved. Given that Shin is struggling with war trauma, his Dissonant Serenity is a sign that something is off.
Hao Asakura from Shaman King. Oh, dear god, HAO. He has quite a reputation for having that cheery smile on his face as he slaughters countless lives, especially lesser Shamans, including but not limited to almost all of the "pathetic" X-Laws. He even has his serenity when he does worse to Yoh by pulling out his soul and eating it in the fourth-to-last episode of the anime.
Shiota Nagisa from Assassination Classroom outwardly looks like a sweet little slightly androgynous milquetoast kid. And he will continue to look like that even as he makes elite veteran soldiers shit bricks with the sheer killing intent hiding just underneath the surface.
Natsume from Beelzebub is almost invariably smiling, even while his (albeit short so far) fights.
As shown in Episode 8 of Servant × Service, Saya keeps that sweet smile of hers even with Cross-Popping Veins and a dark aura emanating from her while relaying a message to Jyoji via Yutaka that dragging a female (i.e. Lucy) into a date is awful.
Cyclops of the X-Men frequently displays this attitude in combat. Including, on at least two occasions, while fighting blind. He's just that much of a control freak.
You would not believe the day I'm having.
Victor Ray from 100 Bullets is able to keep his emotions in check and can execute his mission utmost efficiency. One time he was able to give off a lecture about the origins of the trust IN THE MIDDLE OF A GUNFIGHT without even breaking a sweat.
Jan Arrah/Element Lad/the Progenitor in Legion Lost, when he explains to the Legion the horrors he's suffered that drove him UTTERLY INSANE. And then he kills one of them because he forgot who she was.
When Tsuruya is almost thrown out of a school window to her death by one of Kyon's classmate in Kyon: Big Damn Hero, Kyon dangles him out of a window by the ankle and interrogates him, while making Shout Outs to The Dark Knight, among others.
The Condesce and Grand Highblood in Hivefled. Which only serves to make them that much more disturbing.
Used as a plot point in the second Rush Hour movie. Steven Rayne, a hotel billionaire, is perfectly calm and serene when gunfire erupts on Ricky Tan's yacht. Carter notices this, telling Lee that "when the shooting started, (Rayne) was way too cool." They eventually figure out he's in on the plan to launder fake money, and follow him.
This may be a stretch for serenity, but Colonel Kilgore in Apocalypse Now doesn't act like a normal man surrounded by gunfire and explosions. "I love the smell of napalm in the morning."
Another example: a pilot and scientist just went rogue to help two prisoners escape (those are the good guys, by the way.) He pauses just long enough to tell everyone "Masks on" before booting open the atmospherically sealed door, striding into the hangar and opening fire on the fleeing aircraft. After a total of about 45 seconds of taking careful aim, firing, and then looking angry/disappointed that they left, he's FINALLY handed a mask and it's shown that he was holding his breath the entire time while looking focused, if not placid. Colonel Badass indeed. note This gets a Lampshade in the RiffTrax of the film. When Quaritch is handed the mask, Bill, speaking as Quaritch, says "Oh yeah, breathing. I guess some of you pussies have to do that."
There was no pause to say "Masks on", there just happened to be enough time for him to say it in moving from where he was standing to the door. Luckily for everyone else it the room, that space of time was a few seconds and no one died from him gassing the place by kicking the door open. Considering his absolute single-mindedness in stopping that aircraft by any and all means... what if he'd been closer to the door?
(This is actually standard military procedure in a toxic environment. Yell "Gas Gas Gas", close your mouth, mask up, THEN exhale to clear the gas from the inside of your mask. If you can't do that INSTANTANEOUSLY in all situations, you are unlikely to graduate. And that's on Earth, now, on an alien world? They would drill that five times a day).
Loki in The Avengers rarely, if ever loses his cool, looking quietly amused even while committing genocide. It's a sign of his impending Villainous Breakdown when he starts showing other emotions in the final battle, going very quickly from a Single Tear when fighting Thor to a full-on A God Am I rant when faced with the Hulk - which ends as well as you would expect.
He continues this attitude in Thor: The Dark World. His reaction to the other prisoners getting released by Kurse is basic curiosity, and during the later prison riot he can be seen calmly reading in his cell (and looking mildly annoyed at the racket they're making).
A character is disconcertingly calm while being gang raped in Baise Moi.
In Battle Royale all versions include the adviser explaining the rules cheerfully, which all include slaughtering your friends, but it's an even worse scene in the film since there's a video featuring a Genki Girl explaining everything cheerfully. The effect is very creepy.
In Inception, when the dream is collapsing and everyone else is running around frantically, what does Mal do? She calmly walks through the destruction and is amused at how Dom gave Saito the wrong documents.
Dorian Gray in the live-action adaptation of The League of Extraordinary Gentlemen. When The Phantom's soldiers begin wrecking his house, he strides calmly through the firefight, looking utterly bored as he stabs people left and right. When one of the soldiers fills his entire torso with lead, he just stands there, takes a deep breath, and then cuts off the guy's breastplate and stabs him. As soon as the guy falls, he takes the handkerchief out of his breast pocket, wipes the sword clean with it, and puts it back in a dignified manner. To be fair, when you can't die by being shot, you'd be pretty confident and uncaring too.
In The Matrix films, various characters wear completely blank expressions while fighting, often further emphasized by impenetrable sunglasses.
Crazy Wanda, while everyone is being maimed by Bigfoot at the end of Night of the Demon.
In 9, apart from briefly screaming at 9, 6 was very calm before he died.
The death scene of Lord Beckett in Pirates of the Caribbean: At World's End. He calmly walks down the middle of his ship as it's being torn apart by cannon fire on both sides in slow motion, muttering to himself that it's "just good business." Though one could argue that that was less Dissonant Serenity and more a very calm Villainous Breakdown.
Gary Oldman's character in Leon, The Professional when he's killing Matilda's family while cheerfully humming along to the classical music in his headphones.
The Purge: The announcement made by the government to the people about The Purge makes it sound like it's just a minor, adjust-your-clock event. This contrasts starkly with the home invasion that occurs later on.
Captain Miller, in Saving Private Ryan, is astonishingly calm during moments of phenomenal stress, i.e., the Normandy Landings. The problem is, his jitters catch up with him later; No matter how calm he may appear, Miller is a man on the ragged edge who knows he's right on the point of losing it. Ironically, this lends him the serenity he needs to be a Father to His Men.
More appropriately, Amon Göth from Schindler's List fits the description to the tip, as he walks around the camp, casually glancing about while Jews are murdered and tortured. "Can you believe this? As if I don't have enough to do, they come up with this? I have to find every rag buried up here and burn it," he says as he watches the incineration of Jews' bodies.
Kevin, from the movie Sin City. Oh god, KEVIN. He even smiles as his HEAD is being cut off.
Star Trek III features Kirk stuck with a Klingon being about as calm as hammy TOS-era Klingons get (as in, shouting monotonically) either because he's in the catbird seat or in some sort of battle trance:
In Thunderball, Largo calmly glances at a SPECTRE henchmen being electrocuted by Blofeld, then goes back to looking through his notes with a slightly bored expression throughout.
Garland Greene from Con Air. He's a deranged serial killer who rarely changes his expression and speaks in a Creepy Monotone (and also a Deadpan Snarker with shades of Affably Evil). The serenity is most contrasting when the plane crashes, and he hilariously sings "He's got the whole world in his hands".
Kelly's Heroes has 'Oddball'. He's a 'Proto-Beatnik' (it's only the 1940's) and thrives on 'positive waves'. He also settles down for a picnic deep inside enemy territory while his crew tries to fix their damaged equipment, since "...everybody here seems so friendly." Oh, and did we mention he's the best damn tank commander in the whole division?
…Bolli does not kill Helgi on the spot. Instead, he stands quietly by and smiles a little as he listens to the summons. Saga readers know of course what it means to smile a little under the pressure of insult: it means turmoil and violence. The little smile seals Helgi’s fate […] it is only a question of time. (Theodore M. Andersson)
Fiver may have used this trope in Watership Down to defeat a larger rabbit by being overly polite and calm for the situation, freaking the other guy out.
Chiun from the book series The Destroyer matches this. An 80 year old Korean man, he is calm and gentle... as he rips open throats and kills anyone who messes with him.
In the Star Trek novel Vendetta, a survivor of a Borg attack on his world describes having seen the personification of death. Much like many cultures on Earth, his had portrayed death as a skeletal figure in black, but instead he describes death as a smiling child walking and skipping through the scenes of destruction.
Captain Tushin and Prince Bagration exhibited forms of Dissonant Serenity during the Battle of Schöngraben in War and Peace. Captain Tushin might have briefly lapsed into Psychopathic Manchild for his disturbing calm though.
Lara and Thomas Raith, whenever we see them fighting.
Harry himself during a flashback in White Night, while he tortures a ghoul to death.
"Dios." Ramírez breathed. He stared at me for a moment. "I've never seen you like this." "Like what?" "Cold."
Warrior Cats: Everyone. They aren't outright happy or excited (except maybe Lionblaze), but no one seems to be at all fazed by all the bloody battles in the series. Quotes from various characters:
"I'd welcome any cat who'd help me rip out their entrails." "Just a few scratches. Mostly WindClan blood." "Is there any blood?" (Said by an excited little kitten)
Most of the time, their battles are non-lethal. They fight to prove their superiority and defend their homes, not to kill, which even in battle is considered outright murder. When a cat accidentally dies during a border skirmish it is a huge deal. When a life-or-death battle actually happens, they are much more serious about it.
Sol stays calm and composed all the time, even when surrounded by enemies and accused of murder. He is so calm, other cats often find it unsettling. The only times he's lost his cool is whenever he's making a speech (and he's really more "incensed" than angry), and when Hollyleaf apparently pushes his Berserk Button, he recovers in less than half a second.
Jonah in The Bible, with the boat he's on going through a storm and the pagan crewmen about him frantically praying to their deities... is asleep. So, pretty old trope eh?
So was Jesus, one of the times they were crossing the Sea of Galilee. Another time he was so zen he was able to Walk on Water.
Over the course of countless pressures, near death experiences, sacrifices and losses and manipulations, Rand Al'Thor, The Dragon Reborn of The Wheel of Timehad become increasingly volatile, prone to losing his temper at the drop of a hat (oh, and he heard voices a lot), but in book 12 his slow building psychosis reached its zenith when he is almost captured by Semirhage and forced to almost kill the woman he loves, and he becomes this trope for the rest of the book, greatly freaking out those already familiar with his building insanity.
Roose Bolton, Lord of the Dreadfort, is a polite, soft-spoken and unassuming man, as well as the closest thing Westeros has to an Evil Overlord (and a Token Evil Teammate to the Northmen, too). Even when ordering horrible atrocities upon the peasants and prisoners of war, or threatening to cut off his cupbearer's tongue for speaking out of line, he never raises his voice or loses his calm. Bolton believes in purity and self-perfection, practising a strict health regimen for himself, and seems to be of the mindset that emotions are unnecessary, unlike atrocities.
Mace Windu in Shatterpoint. "I don't like Windu... he has the same look cleaning his weapons as he does using them."
In the NUMA Series novel Valhalla Rising, at one point the hero Dirk Pitt is desperately throwing stuff at The Brute, but gets his clock cleaned. In steps his friend Al Giordino. The Brute tries to crush Giordino; his response is to reach out and start strangling The Brute, cool as you like. Eventually The Brute, running out of air, is forced to concede.
Sir Thomas Maculay in Lays of Ancient Rome describes Mars this way:
He smiles a smile more dreadful Then his own most dreadful frown When he sees a thick black cloud of smoke Rise up from the conquered town.
Played with in the Dale Brown novel Warrior Class, where POTUS Thomas Thorn's incredible calmness even in tense situations is comforting to some, annoying to others.
As Rudyard Kipling in "The Ballad of Boh Da Thone" described The Captain remembering old times when he tried to catch his archenemy:
In his eye lit the passionless passion of slaughter
In the Forgotten Realms novel The Making of a Mageresentful Elminster (age 17) witnessed how one magelord summoned and tried to command Dorgon "Stonecloak" Heamiiolothtar, one of few people who didn't won the office of Magister, but was given it by the gods of magic and remained in it longer than anyone save Azuth himself. Dorgon poked "with mild curiosity" the artifact supposed to make him powerless, ascertained that it is a challenge, teleported through the room and diced half of the magelords and they flunkies present at the party before anyone reached the door. Then disabled, judged and beheaded all present magelords one by one. All the while wearing much the same expression, ignoring their spells and complaining about their inability to throw at him something really interesting.
In Discworld's Nightwatch, Carcer is this trope. This man will smile serenely as he's stabbing you, and then with a look of childlike innocence, go "Who, me?" to any bystanders, as if he didn't just kill someone in cold blood.
During Act I, Scene III of William Shakespeare's Julius Caesar, a heavy storm hits Rome, the earth shakes, fire is seen in the skies and lions, ghosts and burning men walk the streets of Rome. And into this, enters Cassius, who smiles contentedly and calls it "a very pleasing night to honest men."
Later Mark Antony imagines a similar situation in which Ceasar's ghost stands beside Ate, the Goddess of Vengance "come hot from hell ", he then yells ""Havoc!" " and she lets go of the leashes to a pack of Hell Hounds borrowed from Mars himself, engulfing the whole country of Italy in a bitter war that drags on so long that the people become so accustomed to the carnage that "mothers shall but smile" at the sight of their children's bodies being brought home so horribly mutilated that they are barely even recognizable anymore. Though the fact that these thoughts fill him with the warm an' fuzzies is another matter entirely, one with elements of several Revenge Tropes involved.
In the Honor Harrington novel In Enemy Hands, when Honor is in State Sec custody, she finds that the "deadness" and "cold-eyed patience" of some is even worse than the others' fiercely delighted hatred. In Echoes of Honor a similar observation is made of Oscar Saint-Just.
Sisterhood Series by Fern Michaels: In the book Collateral Damage, Paula Woodley talks to Lizzie Fox about her husband Karl Woodley. She asks Lizzie if she's being too sadistic, and she says this in the tone of someone discussing the weather. She had been abused by her Domestic Abuser husband for years. No decent person could fault her for wanting to make him pay for that!
In Galaxy of Fear, the shapeshifting Hoole just frowns in concentration while wresting with the controls of a crashing ship. He's that calm and steady when tossing his endangered niece and nephew something that will help. He's less calm in day-to-day dealings with them, not being a fan of children.
In Neuromancer, Molly recounts how she and her companion were stalked by a vatgrown ninja assassin whose face remained serene even as he fought. Later, Hideo is struck blind by a flash attack, yet doesn't even flinch, but proceeds to stalk his enemy by sound, calm as can be.
The Cybermen can apply as well. The Daleks have one emotion (anger), but all that's left of the Cybermen is pure logic.
Series 6 offers both the Antibodies ("You will experience a tingling sensation and then death") and the robots in the Two Streams hospital ("This is a kindness.") Basically, evil robots in the Whoniverse are either absolute monotone or this. No, the Daleks don't count, they're not robots.
The Doctor himself applies as well, especially the Tenth and Eleventh ones. You know he's mad when he starts yelling and screaming, but when he gets quiet again you know it's time to be scared.
A famous example from the classic series episode, "Horror on Fang Rock":
Doctor: [with a toothy grin] Gentlemen, I've got news for you! This lighthouse is under attack and by morning we might all be dead!
In "Dinosaurs on a Spaceship", after learning the fate of the Silurians who built the spaceship, the Doctor informs the space-pirate responsible that he's not going to rescue him from the oncoming missiles. When the villain begs for his life, the Doctor's response?
Doctor: I wonder if the Silurians begged for mercy?
From Joss Whedon's Firefly: River Tam displayed this trait in a few episodes. But then, she was batshit, so that is also to be expected.
A more typical example is Wash, at least as long as he's piloting; check out the scene in the pilot episode when the Reavers are chasing them: he's the only one in the entire ship who's completely calm. Wash's dissonance works both ways: He's very calm when, say, he's being chased by Reavers or has to pull off some crazy ass aerial stunt, but he acts panicked when things really aren't that bad.
He is a leaf on the wind. Watch how he soars.
On Buffy the Vampire Slayer in the finale of season 5 - Dawn realizes that she is going to be sacrificed in a ritual to open up a portal and bring about an apocalypse; she responds by calmly folding her clothing and placing it on a chair, in case that is the only thing left of her after the ritual is done.
Gem and Gemma from Power Rangers RPM have the same cheerful smiles on their faces whether they're talking about friendship, explosions, military strategy, or the horrible conditions at a forced-labor factory they spent several months imprisoned in.
Subverted by a Japanese monk in Lexx, who serenely keeps meditating and is ignored by the wandering alien probe droids. It turns out he's not meditating, just briefly unconscious from having donated half his insides to an organ-harvesting cult... and the probes only ignore him because the surgery sewed shut his "poop chute."
Charlie Crews in Life. Most of the time. When he thinks he's on to the people behind his framing, however, he chucks all that Zen stuff out the window. In one scene.
Snafu in The Pacific. Snafu's usually deadpan calm whether he's just shooting the breeze or prying gold teeth out of a dead Japanese soldier's mouth. When Sledge admits he's scared and Captain Ack Ack states "Everyone is; any man who says he's not is either lying or dead", a quick shot of Snafu makes you wonder what that makes him.
He also manages to sound calm about things when it's apparent that he really isn't. When Snafu talks Sledge out of taking up his own habit of prospecting for gold teeth among dead Japanese soldiers, his warning about "diseases that'll make you sick" is less his worrying about hygiene and more a cover to let him express his concern about the comparatively idealistic Sledge starting down the same road he's traveled.
Despite everything, Okinawa almost breaks him: he nearly starts a fight with Sledge, who's probably the person he's closest to, and it's only after Peck climbs up on an exposed ridge and fires at the enemy and Hamm is shot saving him that he seems to go back to his usual self. Even then, there's still a slight change in his demeanor.
The Sci-Fi Channel's miniseries adaptation of Dune had a minor Harkonnen officer who was a Mook Lieutenant. When said officer's troops get ambushed by the Fremen, he fights back until he sees Paul Atreides calmly walking through all the bloodshed and explosions and coming straight at him. The officer promptly tries to run, but he doesn't get far...
(*Lana grabs her head and smashes it against the wall, then throws her down the stairs*)
Chloe: (*Struggles to her feet*) Lana, what are you doing!?
Lana: Killing Chloe Sullivan.
This is just the start of probably the worst beating Chloe ever got. Lana remains expressionless the entire time. No, they aren't fighting over Clark. Lana is mind controlled by someone who is going to be exposed by Chloe.
Another episode involves Clark and Lionel Luthor switching bodies. In order to lure Lionel-in-Clark's-body back to the prison to reverse the process, they manage to convince him that the change will be permanent if he eliminates his old body. In order to do this, he stages a full scale prison riot, then walks through the chaos with the most supreme confidence.
Cure: A doctor calmly states to Chloe that he is going to cut out her heart.
In Supernatural, a group of pagan gods meet to discuss about the upcoming Judeo-Christian apocalypse. Lucifer finds them, explains his disdain for the pagans to Mercury, and calmly kills each and every one of these gods (except for Kali, who got away).
In The Mentalist after killing the Red John imposter, as everyone in the mall runs screaming Patrick sits down and finishes off his tea while asking for a check.
In many cases Patrick displays far more calm and control than seems sane in tense situations.
Brother Mouzone of The Wire. Whether firing a warning shot into someone's arm, lying on the floor gut-shot, or sitting in a folding chair reading The New Republic, it's all the same to him.
Same for Marlo Stanfield who orders many murders with the same level of emotion you would expect from someone ordering a sandwich.
The little girl in Alien Abduction: Incident in Lake County is disturbingly unemotional, considering that aliens are abducting/killing everyone in her family. In the end, she is so passe about the whole thing that not only does she let the aliens into the house, but she is the only one seen going with them willingly as opposed to the others, who are all put into trances.
Data of Star Trek: The Next Generation displays this as part of his very nature. Despite regularly being in life-threatening situations, he is almost always calm and detached.
As does his spiritual predecessor Spock; though being half-human, strong emotions occasionally show through his cool veneer.
The Female Changeling in Star Trek: Deep Space Nine maintains a calm demeanor throughout the series. Her serene fascade cracks in the final episode.
This is less to do with the aforementioned factions fitting entirely into the trope (plenty of Eldar are quite Axe Crazy in battle and when they speak at all Necrons are more Creepy Monotone) and more to do with how every single other faction is ALWAYS SHOUTING! ALL THE TIME! and as a result they seem positively catatonic in comparison.
Friend Computer in Paranoia can embody this trope, depending on how the game-runner decides to depict its voice.
Friend Computer just wants you to be happy. Happiness is mandatory. Failure to be happy is treason. Treason is punishable by summary execution.
Please report to the nearest Internal Security office for routine brainscrub therapy. Thank you for your cooperation. Have a nice daycycle.
In Dungeons & Dragons Fourth Edition Monks are portrayed this way, at least in the fluff. Although obviously up to the player on how they act, most powers are described as something along the lines of "floating through the chaotic battle like a leaf on the wind." While, incidentally, executing Rapid Fire Fisticuffs or simply sending entire enemy groups (or one giant dragon/demon/abomination) flying with a "mere flick of the wrist."
Nyx Avatar: Let us finish this! It is the path of your choosing!!
The main character when he prepares to summon his Persona for the first time. Just calmly whispering Per so na
The Engineer in Team Fortress 2, who in his Introduction Trailer peacefully plays guitar and drinks beer while 210+ attackers are being slaughtered by his turrets.
Additionally, the end of the "Meet the Sandvich" trailer has the Heavy standing on a ledge and eating the eponymous sandwich while battle rages around him.
And most of the Spy's Man on Fire soundbites, "I appear to have burst into flames" and "I do believe I'm on fire", are delivered far more coolly than the panicked cries and screams of most of the other classes'.
One of Medic's taunts involves him playing his bonesaw like a violin. In the middle of a chaotic battlefield.
Meet The Pyro shows that he views the world as a Sugar Bowl, and spreads rainbows and happiness. In reality, she's torching everything and everyone in sight.
Yuyuko Saigyouji from the Touhou Series, even though she is portrayed as a Big Eater with Obfuscating Stupidity most of times, possibly belong to this trope when she fights seriously. This feature is evident in Perfect Cherry Blossom.
Dimentio of Super Paper Mario fame. What makes it even creepier is that it's never actually revealed whether he's wearing an actual mask, or it's his face.
Suikoden V has Sagiri, a former assassin turned detective who always wears a smile. She was conditioned from a young age to always smile, mostly because the Queen Bitch assigned to training her thought it would be funny to see people killed by a smiling little girl. One other character, Nakula, watched his father get killed as a child, and her smile is the reason he recognized her as an adult.
Eve from Parasite Eve. Her openingact consists of her setting the entire opera troupe and audience on fire through the power of her awakened mitochondria. She continues to sing her aria as calm and detached as she can be, even as the stage itself catches fire and blazes all around her.
The fighting game BlazBlue features a young boy named Carl Clover, whose profession is bounty hunter. He is accompanied by his "sister", a semi-sentient doll/bio-cyber weapon which has long, sharp claws and is fueled by Carl's subconscious hate and desire to kill. Carl lets his courteous manners and innocent smile slip on a single occasion - namely, when Haku-men fills him in on this.
That doll, Nirvana really is his sister. Gotta love alchemical experiments. Cleverly, the game initially implies that Nirvana (the doll) is driving Carl to his madness. Then Valkenhayn talks to Nirvana, and it's revealed that Carl's insanity is hurting her. Meep.
In Dead or Alive 4, both Helena and Christie remain completely calm in their pre-showdown conversation, even though they're in a skyscraper that is being rocked by explosions and is sure to collapse at any moment.
This is even more jarring for Helena, who has just found out that Christie was the one who killed her mother when trying to assassinate Helena.
Walter, the Implacable Man of Silent Hill 4, who never drops that creepy smile of his, not even when his face is splattered with blood or when he's being shot at.
And this song from the same game qualifies. It sounds like something that would play in a safe area. Here's a hint: The section it plays in is anything but safe.
In MOTHER 3, at the end of the game, once you've reached the very top of the tower, before you face the Final Boss, the happiest, most light-hearted songs from the trilogy play. As for the boss himself, the mastermind behind the Crapsack World your home has become, Porky Minch, he's surprisingly calm and cheerful, despite the bombastic battle themes and the fact that he's now an Omnicidal Maniac.
Wilhelm, the Big Bad of the Xenosaga trilogy. He's eternally calm and placid throughout all three games and only appears to exhibit bemused intrigue over everything. His Villainous Breakdown moment in the Grand Finale consists of a single audible gasp. Dude is ice cold.
Neverwinter Nights does not possess the capacity for characters to change their facial expression. So people in combat and close to death have exactly the same expression as people sitting in a garden eating breakfast. The voices and the music do change in combat, though.
Samara from the Mass Effect series fits this one: snarky pilot Joker remarks that she could probably shoot him "in a very tranquil way...which does not make me feel any better about it."
The LOKI mechs also count; their calm and polite "Please reconsider your agressive attitude" lines while being set on fire or shot to pieces are actually quite creepy.
Joker himself. Well, at least in Mass Effect 1, he's dead calm when doing the impossible (with everything on the line). In Mass Effect 2, he's more laid back in such situations, though still pretty stoic.
And during his battle with Cloud in Advent Children. His expression upon being defeated is a look of mild surprise.
In fact, Sephiroth's been made to be a Triumphant Example of this Trope. You will rarely hear him raise his voice or shout (even when he is being struck by a weapon), he never loses his composure, and he will usually have either two looks: an amused smirk or a just a simple frown. Oh, and don't ever expect to see him bleed.
Yuna subverts this trope when you find her in Bevelle. After the Mexican stand-off where Seymour threatens to kill the party if Yuna doesn't calm down and marry him she threatens to jump off a fucking huge precipice to her death. She gets her own way, but threatens to do it anyway, insisting "I can fly." Okay, sure, crazy lady. As she falls, she summons Valefor, proving that her confidence and serenity was perfectly justified after all.
Half-Life's G-man remains cool and businesslike in corpse-littered, alien-ravaged Black Mesa.
In Metal Gear Solid 3, the Cobra Unit each used a codename taken from the emotions people feel on the battlefield. Thus, The Pain, The Fury, The Sorrow, The End. What was The Boss's codename? The Joy. She does stay relatively calm throughout, too, even as she knows she'll die.
Interesting case. Although The Joy remains relatively calm, she is not shown smiling through much of the game. The Sorrow on the other hand is rarely seen unhappy, even as he's sending the ghosts of everyone you killed after you.
This trope is DEFCON's bread and butter. As all of civilization is destroyed in a nuclear war, the player watches things unfold through a tactical computer depicting the carnage through simple wireframe models and numbers. This is accompanied by quiet piano music.
Hear the female trainer spout off all her cheerful motivational lines in Wii Fit and you'll think nothing of it. Hear her say those exact same lines while beating up opponents in Super Smash Bros., however, and you'll come to see her as a surprisingly demented lady.
The Villager, a fellow newcomer, also gives off this impression with that simple, unfitting smile of his. It's so off-putting that many fans started depicting him as having serious problems as soon as he was revealed.
Many of the inmates in Outlast have a very calm attitude despite the living hell around them. Notable examples are the duo you encounter throughout the game who watch you from a distance calmly discussing that they are going to give you a running start before tearing you apart, and who gets what body part. Also the doctor who chats with you like friend even when he is torturing you, cutting off a couple of your fingers, and later chasing you.
She also flies in to impassioned rages at the drop of a hat. I.E. The very next strip.
This the basis of the xkcd "Roller Coaster Chess" (aspired to meme): people taking advantage of cameras on roller coasters to get in pictures of themselves pretending to focus on a game of chess instead of throwing their arms out and screaming like the rest of the riders.
Frankie And Stein has Stein acting this way... a lot. From graverobbing grinningly, to stealing a brain with a grin on his face, to excitedly explaining what he's going to do next half-way through creating his own Frankenstein's Monster with blood all over his face. Only, he's a little more upbeat than serene. This strip, in particular.
Nuzlocke Comics: The creator's White run uses this a lot. Cheren and Bianca are Creepy Children with perpetual smiles even after Hilbert's suicide, and N's Pidove at Nacerene City does nothing but softly coo as it turns Hank the Pansear into a Gory Discretion Shot. Coo.
General Asanee from The Salvation War, whose calm is so scary she doesn't need to swear.
Futurama: Bender's cigar starts a fire in a museum exhibit containing very rare, and flammable, silk tapestries. Soon the whole room is ablaze, with everyone cowering in fear. Except for Fry, who spent the whole episode drinking coffee (spending his $300 rebate on 100 cups of coffee). He drinks the last of the 100 cups and turns from a gibbering mess into a paragon of peace and serenity. He is able to put out all of the fires and rescue everyone while moving in extreme fast motion (Leela would later attest to seeing only a bright, orange blur).
Overlapping with their Casual Danger Dialogue, in the Kim Possible episode "Ill Suited" once they sort out their relationship problems Kim is all smiles while fighting a battle-suited Ron, even though the person remote-controlling the suit is trying to kill her.
Happens several times on Moral Orel, such as Orel standing cheerily in a Blood Bath (made up of his friends' blood) as they stand around him, faint from the loss.
The Disaster Girl meme embodies this to the fullest, the picture being a girl no older than five smiling almost sinisterly into the camera while firefighters are putting out a burning house in the background.
Title of a Sports Illustrated article: "Joe Mauer Will Serenely, Politely Crush You."
In traditional art, angels are often portrayed this way when in battle with demons, they could be exhibiting Tranquil Fury, but the former is more likely.
A fundamental characteristic of Hindu gods. Under absolutely no circumstances are they to be portrayed with anything other than a completely stoic, non-emotional face no matter what the situation is. A god can be neck-deep in demons and oceans of blood and fire, but he's gotta be cool about it.
In a stare-down, the guy who stays composed in the face of bluster, threatening gestures, maybe even a brandished weapon or two can be far more intimidating than the other. Only a fool or someone supremely capable can remain calm in a volatile situation.
An arguable real-life example would be in Canadian Politics; during the recent Leaders' Debate, Stephen Harper (the current Prime Minister) managed to remain very calm even as the debate got increasingly heated and the questions from his rivals increasingly armor-piercing. Sure, it isn't VIOLENT so to speak, but it got pretty intense, and Harper managing to keep as calm as he was is either impressive, or creepy, or both, depending on what you think of the guy himself.
It really helped him that he was being grilled on all the wrong issues and that his\Conservative core values were hardly questioned at all. Just as one example, the PM put forth a plan to buy jets to replace the ones that will be retired in 5 years. Instead of attacking the plan for only researching one company, supposed kick-backs, not a good value, etc, the opposition continuously and passionately argued that we simply shouldn't buy more jets. So Harper calmly explained that a country can't operate militarily without jets. That said, he acts calm under fire too.
From the realm of sports, specifically MMA, Fedor Emelianenko absolutely belongs here. Never has a a man made whaling on another man's face look more serene.
As another Real Life example, military envokes this. For example, radio protocols state what you are to say in most "What if" events. Say, you are a radio operator and you and your platoon are on a patrol, then you have contact, and you are being shot at with RPGs, AK Ms and Dsh K and what not. Company command has reports of gunfire being heard, and contacts you over the radio, asking for sitrep. Your answer? Instead of "Holy shit we a being shot at!" or something, it's "Contact-contact, Wait, Out". Similarly, MEDEVAC 9-liner (my buddies just got shot, get them outta here!), Contact Report (We were shot at, killed bunch of dudes and some of ours were!)... It's justified trope, however, since communication is vital and should be clear and easily understandable at all times, even more so in critical situations.
Police, trauma doctors/nurses, EM Ts and firefighters, as well as other people with high-pressure, intense jobs are often this as well.
