The super-stoic Amasawa Yuuko from Dennou Coil breaks down crying when it is revealed that her brother has been Dead All Along, and all her efforts to revive him from his "coma" have been for nothing.
Just one chapter in the Black Jack manga, but the "Black Queen", a female surgeon known for her cool, unemotional efficiency in amputations. Even her fiance is freaked out by how cold she is about her work. But then she has a drunken emotional outburst all over Black Jack — and later learns that she'll have to amputate her lover's leg, which sends the woman into complete emotional collapse. Black Jack sedates her and manages to save the leg.
While Zelgadis Graywords of Slayers isn't entirely stoic - he enjoys good company and can occasionally be as mischievous as Lina and Amelia - he certainly never lets himself be vulnerable, and his default mood is a mix of stoicism and condescending snark. Come the fifth season of the anime, he learns that he can never turn his chimeric body back to its original human state, ever, from his great-grandfather, a man he loathed, he starts to openly weep and yell.
Ciel Phantomhive from Black Butler hits this trope hard when he has a panic attack in the manga.
Phonsekal Laure from Tower of God usually appears as a very reserved, lazy but kind of high and mighty guy. Turns out he is one of the most childish whenever it concerns his Safety Blanket and Companion Cube.
L from Death Note who is usually even talkingwithout any emotion, freaks out when he watches the 2nd Kira's video tape mentioning Shinigami. Also, the one instance he actually smiles...
When L tries to reason with an increasingly irate and determined Aizawa during a argument between the two after Ukita's death in the middle of the second Kira's first broadcast, Aizawa angrily grabs L's shoulder and discovers to his surprise that L is trembling with fear and anxiety despite the near-absolute calmness in his voice and the impassive expression on his face. He's just as upset about the situation as Aizawa, but hides it and refuses to let it cloud his judgement.
The biggest example is Robin. She showed little to no emotion from the first time she was introduced as The Dragon, and continues being stoic even after joining the Straw Hats. Then comes the CP9 saga, the majority of which is dedicated to this trope; when Robin's Tear Jerker past comes to bite her, she starts showing genuine fear, anger, and sadness. The apex comes after seeing her companions declare war on the World Government for her sake, after which she tearfully screams "I WANT TO LIVE!" She goes back to being The Stoic at the arc's conclusion, though, as though nothing had ever happened...though she's gradually started showing more and more emotion since then.
And it seems that she's slowly slipping into a lesser Stoic status as of the Dressrosa arc: after several hundred chapters of being the calmest person in the world, she has finally adopted her crew mates' habit of showing overreactive faces. Those dwarves just don't get it. And she has another, even biggerWild Take a bit later in same arc when talking with some toy solders.
Zoro has only cried about three times thus far in over 700 chapters, and two of them were when he was a kid. This is because Zoro is SO STOIC that he can make a Tear Jerker out of standing there, staring off into the distance, and saying "Nothing happened!" While covered in blood. Though as stoic as he is, he's had his fair share of wild takes alongside the other Straw Hats...except for Robin, of course.
Marco, the first Commander of the Whitebeard Pirates, usually maintained a stoic reaction throughout the battle. However, he visibly lost his cool when Whitebeard was stabbed by one of their allies, when Ace dies and when Whitebeard himself dies.
Jimbei is usually one of the most focused characters in the series. But he lost his cool in regards to Ace's death and cried Manly Tears when Nami forgave him. On a lighter note, he got a Wild Take when he saw Princess Shirahoshi and an injured Hachi with Luffy.
He got another Wild Take when Luffy is more concerned about food than the important information Jinbe was telling him. After getting angry with Luffy who cheerfully tells him that he likes to leaves things to chance, Jinbe then goes into a minor depression.
In Chapter 597, Dracule Mihawk thinks that training the man who wants to take his life in battle is hilarious, so he actually laughs when Zoro begs him for training.
On the next page, it shows Mihawk agreeing to train Zoro. The look on Zoro's face also falls into this trope. He looks so happy and bright-eyed, like a little kid that got exactly what he wanted during the holidays.
Doflamingo is always seen smirking, and almost never stops pre-Time Skip. Even then, it was only due to puzzlement. However, when Law cuts the SAD, Vergo, and practically the entire island of Punk Hazard, all while giving a New Era Speech to him, Doflamingo actually shows frustration for the first time ever.
But nothing can compare to the sheer rage he exhibits when Law gives him a Sadistic Choice after taking Caesar Clown hostage. He was stuck between a rock and a hard place: either he would give up his position as a Warlord and get Caesar back, or keep the position and be unable to produce SMILEs. If he takes the former, the Admirals won't stand idly by anymore and hunt him down. But if he takes the latter, he'll anger Kaido of the Four Emperors and get wiped out. After being given this choice, Doflamingo loses it and starts going on rampage on Punk Hazard, slaughtering G-5 marines and giving Smoker a severeNo-Holds-Barred Beatdown, all while demanding the heads of the Straw Hats and Law. Forget the SAD thing; this is when he really got pissed off.
Trafalgar Law is seen as a lesser example of The Stoic; he's smug, smiling, takes battles casually, and is not above showing emotion at times. However, he is unmistakably serious in all aspects, which leaves him rather bothered by the Straw Hats' quirks after they form an alliance. Examples include tying Chopper to his head, Luffy not following his plans, and the Straw Hats' absurdly nonchalant behavior in the calm before the storm. The first instance of this trope is shown after their victory on Punk Hazard, when instead of fleeing, they throw a party. Law is shocked, but ultimately joins in, albeit managing to keep his Stoic appearance intact. 4 chapters later, however, when he realizes that he's grown too used to the Straw Hats' casual pace, he is FLABBERGASTED.
A particularly heart-wrenching example in Wolf's Rain, when resident tough guy Tsume breaks down and openly weeps after Toboe's death.
In the same series we also have Darcia, the cool, quiet and enigmatic noble who completely loses it when he returns home with Cheza, (she of the Healing Hands) to save his Ill Girl fiancee, only to find that his fiancee was murdered shortly before his return. He doesn't take it well.
Victor of Medabots prided himself on his totally professional, detached approach to battling and expressed little save cold distaste for the rest of the world. He managed to keep this up when the family of one of his opponents invited him round for dinner but we get to hear his internal monologue for the first time, and during their actual match he completely loses it when his opponent refuses to give up. At the end of the series his Medabot is destroyed protecting him and his mask breaks noticeably, leading to him actually giving the main character a smile at the end.
Faye Valentine appears at first to be calm, collected, and manipulative. However, seeing a tape she made as a child (which she can't remember) and not having a home anymore clearly affected her deeply. The last we see of her is her crying her eyes out after Spike has gone to fight Vicious.
Gundam 00 gives us The Stoic hero Setsuna F. Seiei screaming his lungs out of grief over a certain comrade "LOCKOOOOOOOOOOOOONNNNN!!!!!"
Aila Jyrkiäinen from Gundam Build Fighters is introduced as an icy, detached super sportsgirl who curbstomps her opponents with her Qubeley Papillon model. Later episodes, however, show her as anything but detached when it comes to food and those who come between her and food. This is especially the case whenever she bumps into fellow Big Eater Reiji.
Rei of Neon Genesis Evangelion is heavily implied to have fallen in love with Shinji by the end. Either that, or developed motherly feelings for him since she's partially a clone of his mother, and is choosing him over his father Gendo to become the "Messiah" of instrumentality in End.
Gendo himself does this twice in the series proper. The first is when Rei's Eva goes berserk, and he severely burns his hands in his rush to get to her afterwards (opening the superheated release mechanism for her entry plug). The second time is when he orders the activation of Unit-01's dummy plug (autopilot) when his son's life (as well as the Eva, which contained the soul of his wife) was threatened by the 13th Angel. The look on his face shows it in the Japanese version, but the English dub has him swearing and yelling at his subordinates.
An interesting instance, as in the Rebuild, Gendo still orders the activation of the dummy plug but as the frenzied Evangelion proceeds to tear the Angel/Evangelion-03 to gibs, we see a satisfied smirk from Gendo in spite of the carnage that forces Maya to turn away and bury her face in her hands, and the others on the bridge to watch in silent horror. It is also one of the few (or possibly the only) time Gendo has ever really smiled since Yui died.
In End of Evangelion Gendo flat out panics on a level not seen before when Rei absorbs the Adam embryo in his hand into herself and initiates Third Impact on her own with both actors in English and Japanese making it clear from their tones of voice just how screwed Gendo knows he is now that his Laser-Guided Tykebomb slash surrogate daughter slash clone of his dead wife has effectively told him to fuck off and die. And in his final scene he flat out states that the reason he has been so distant to Shinji is because he was afraid he'd only hurt him.
Rei meanwhile looks at what happens with the dummy plugs, and she looks pretty freaked out (for her,) at least as much as she does when she sees Shinji rip apart an Angel and it's hinted that she would find the truth about them horrifying enough to turn on Gendo.
Let's not forget Ritsuko's breakdown in the Dummy Plug Plant, where she starts screaming and crying for her mother. Bear in mind she's somewhere between Rei and Gendo on the scale of stoic-ness. Ironically, her reaction upon realizing that Caspar, the Magi who represents her mother as a woman, has chosen Gendo over her when she attempts a Taking You with Me by blowing them all up is tearful but fairly composed after the initial shock wears off, with her simply stating "Liar" in response to what Gendo tells hernote the exact words of which have only ever been revealed to the actress playing Ritsukobefore shooting her dead.
At the end of Season 1, he turns purple after Nanoha suggests that he's quite nice despite his stoic exterior for suggesting that the TSAB will be lenient with Fate by taking her circumstances into account, and immediately claims that what he said isn't necessarily his opinion.
Heck, Chrono does this several times in the first season and a few times in the second. The kid acts stoic, but the second a cute girl smiles at him (or a cute catgirl shoves him into Marshmallow Hell...) the facade falls to pieces. He's even shocked enough to call Lindy, his mother and superior officer, "Mom" while on duty (before correcting himself) when she allows Nanoha and Yuuno to help them recover the Jewel Seeds.
Signum gives us two more examples from the same season:
She loses her cool and punches the wall when the Wolkenritter find out that Hayate's illness is life-threatening.
She sheds a tear after this exchange:
Signum: "Had we not met like this... we may have been really good friends." Fate: "There's still time for that!"
He also had a truly epic one throughout a good portion of The Second Raid. Beginning when he was ordered to immediately cease guarding Kaname and ending with anotherHannibal Lecture from Gauron, he spiralled downhill into a 10-Minute Retirement and a full-blown Heroic BSOD.
Interestingly enough, in the anime, he never cries. However, in the novel, he actually does break down crying and showing vulnerability... not over Kaname, not over any of his comrades dying... but over his shame and hurt pride that the hostage situation (during the Behemoth Arc) failed to go the way he planned.
On a smaller scale, he also unintentionally breaks his stoic image by, amazingly enough, acting like a Tsundere in regard to Kaname. During the party on the Tuatha De Dannan, Kurz tells Sousuke, "She's pretty, cute, and has a nice sense of style. Any man would fall for her in an instant." Sousuke quickly and coldly responds, "I wouldn't know. I'm not interested." Certainly a response very unlike his normal stoic, clueless attitude.
Ulquiorra Cifer becomes more and more infuriated with Ichigo during their battle in Hueco Mundo, to the point where he actually starts to yell. It's only as he dies that he finally understands the truth about emotion and the value of the heart.
Byakuya Kuchiki had a Hair-Trigger Temper as a kid and, as an adult, his temper is hidden, not cured. He's furious when he learns Ichigo's method of learning bankai has violated shinigami tradition and becomes pure Tranquil Fury when Zommari tries to kill the almost-dead Rukia. However, it's only when he fights As Nodt that his stoic mask shatters completely and the consequences are so devastating it leads to the most brutal defeat in this story's history.
Ghost in the Shell: SAC 2nd Gig. Batou is riding in a vehicle with Gohda when the latter starts questioning Batou about his relationship with the Major, openly asking if he's in love with her. Batou (who clearly is in Unrequited Love with his female superior) keeps his usual stoic expression until Gohda turns to look out the window, whereupon Batou's face twists with anger and he snarls over his comlink: "This guy's a real comedian!"
The Major herself falls into this category as well. She usually is a complete hardened super-woman with a rather dark sense of humour, but she can and WILL break face if you push her far enough. She goes into a murderous rampage against a mech-operator in season one after he nearly broke her body and cries at certain points in season two, mostly involving her feelings towards Kuze.
In Ouran High School Host Club when Kyouya first meets Idiot Hero Tamaki he takes all of his strange antics and outbursts relatively well. Until he blows up at Tamaki and unloads all of the pent up rage and insults he had been keeping inside. It turns out Tamaki was (at least part of the time) deliberately playing up his Idiot Hero side, in order to force Kyouya into this so that he could find out what Kyouya was really like Beneath the Mask. After the outburst, they're closer than ever, and Kyouya knows he's free to occasionally tell Tamaki how stupid he is without ruining their friendship...just like everyone else does.
Mori is also quite stoic, but when the moments where he truly Face Faults are few and far in between, but when he freaks, he freaks.
Tooya from Ayashi no Ceres, who even took the Badass Longcoat to stride, breaks away from his poker face for the first time when the subject of his relationship with Aya is brought up.
Taken even further in one episode where he cries, fearing Aya may die.
And taken even further than that towards the end of the series when he learns that Aya is carrying his child, and he cries again. This time, fangirls swoon.
The Shinigami/Reaper is a quirky example. While not exactly stoic, he usually brushes off any and all situations by being/looking/talking/acting goofy, putting him firmly in comic relief territory. That is, until the Kishin gets loose. Just as the Big Bad is about to flee outright, the Reaper shows up. There's some brief banter, where the Kishin calls the Reaper out on his goofiness, to which the Reaper offers some terse explanation and cuts loose. His voice drops to a low growl, his goofy mask takes on a thoroughly pissed off expression (which is actually more effective than his previous "scary face"), he actually starts swearing at the Kishin and shows everyone exactly why he's the boss.
To be reminded that the Cloudcuckoolander and the usually low-key boy are father and son, just point out something (significant) which goes against their sense of order. Kid also counts for the moments when his calm, matter-of-fact attitude towards being a god is broken by his occasionally hysterical concerns over not being a ''good enough'' god.
Deneve, Clare, and Miria from Claymore were all devotedly stoic up until the Pieta battle, when all three experienced emotional breakdowns over the deaths of their comrades.
Karasu from the Dark Tournament saga of YuYu Hakusho initially seems to be the calmest and most reserved member of Team Toguro. During his battle with Kurama however, he turns out to be much more malicious and brutal than expected.
Kurama tends to be calm most of the time, but after winning a game against Amanuma/Game Master that costs the poor kid his life, he becomes enraged under his stoic facade, instantly decapitating Makihara/Gourmet with his Rose Whip and setting up a plan to defeat Elder Toguro (who was controlling Makihara's body after killing him) while he is still unable to read his thoughts through his rage. Hoo Lee Shit.
All over the place in Darker Than Black, since while Contractors are generally pragmatic sociopaths, they're perceived as emotionless. Thus, they act stoic most of the the time, but there's usually that onething that gets a rise out of them. Particularly memorable moments included Hei completely flipping out at the mention of his sister and the time when Yin started crying.
Hei's character tends to play around with this trope. Compared to other contractors, he's extremely empathetic towards the people around him, and is known to act irrationally based on his feelings.
For a human example, Kirihara starts crying when she hears her team laughing and talking about how they'll support the chief and catch the villain without realizing that their section has been disbanded.
Princess Arika of Mahou Sensei Negima! mostly acts like The Stoic, but finally shows some emotion after Nagi rescues her from execution and tells her he loves her.
In a Lotus-Eater Machine that showed Negi what life would have been with his parents, Arika remains extremely distant and aloof even to her own son. It is very obvious that she cares about him though, and when she holds his hand while walking down the street with him and Nagi counted as a serious Crowning Moment of Heartwarming.
Rather than "distant and aloof", she was more nervous and awkward having absolutely no idea how to treat her own child. Regardless, this still underlines her graduation from The Stoic.
Also, Tsukuyomi managed to sends Fate in a fit of rage by threatening to "steal his kill".
Silver from Pokémon Special. Cool and composed, except for the one time he got a Heroic BSOD when he found out who daddy was. The one moment that really sticks out though, is when he falls over when he sees his wanted poster.
Throughout 90% of Kino's Journey, Kino was the definition of The Stoic. Then, in the last episode (which takes place before the first) she stops in a town, befriends an adorable little girl and is welcomed warmly by the rest of the people. She comes to love it so much that she considers settling down and living there. Eventually, however, the townspeople begin insisting that she leaves, to the point that they all but force her to. Reluctantly, she complies, only to end up watching from a safe distance as a volcano erupts, completely destroying the town and killing everyone in it...including the aforementioned adorable girl. Made even worse when a letter she was given before she left reveals that they knew it was going to happen, but loved their town so much they decided to stay regardless. Quite understandably, Kino flipped out.
Nabari No Ou: Miharu is adorable, and loves to use his sweet smiles and ability to blush at will to his advantage; still, unless it's just to mess with someone, he's extremely apathetic towards basically everything. ...And then he meets Yoite, whom Miharu finds impossible to not care about. Miharu has a few good outbursts here and there concerning Yoite, and even laughs genuinely, but the turning point is his not so stoic breakdown, which leaves him openly sobbing. It's... yeah.
Yoite himself counts. He shows almost no emotion when first introduced, but over the course of the story he has more and more emotional moments, usually concerning his impending death, his desire to be erased, or Miharu.
Used in Naruto to the point where pretty much every developed character who tries to being emotionless (as ninja are expected to be) fails at some point. Shino tries to be cool and calm, but on several occasions is irritated by being left out or unrecognized. Zabuza spent the entire Story Arc priding himself on being an emotionless killing machine, but in-spite of himself flat-out cried when Haku died. Danzo's policy is that emotion just cause trouble, but he outright flies into a rage when it's suggested Kakashi be promoted to 6th Hokage ahead of him. Itachi gives what appears to be a raging Villainous Breakdown but states that is really how he always feelsthen it turned out he was actually a former pacifist feeling so horrible for his Necessary Evil that he's rather happy when he thinks it's all oversubverted Itachi had such a powerful grip on his emotions that his believable act of hysteria may fool any character and even the viewer. Sasori claimed to be as emotionless as his puppets, but at several point when fighting seemed anything but calm. During the present storyline Konan is avoids expressing herself even the entire time she fought her former master, but is vocally upset several time when [[spoiler:Nagato starts pushing his body beyond its limits. I think I'm sensing a theme.
Gaara gets a special mention. When he's first introduced, he speaks in a dull monotone and barely shows any reaction to, well, anything. This seemingly impenetrable stoicism is shattered absolutely spectacularly when he wakes up Shukaku for his fight with Rock Lee, and, later, Sasuke and Naruto; and also when he tries to deal with Might Guy's defense of Rock Lee and his horrible emotional background (thank you, Yashamaru). Sasuke making him bleed for the first time got quite the reaction.
He's also had his moments post-Time Skip, such as when he broke down in tears when his temporarily revived father told him that his mother did love him, contrary to what he was told.
And Pain in episode 167 of Shippuden, what with some of the bizarre facial expressions he pulled.
Sasuke, calm and cool in almost any sitution, even when all the other characters are panicking, laughing uncontrollably, or cheering. But push his Berserk Button (the Uchiha and their fate) and look out.
Kakashi is for the most part very stoic, never really shedding tears at the mention of his dead father and closest friends, but read/watch the Kakashi Gaiden special, especially the end where he breaks down crying at the death of Obito. It's truly heartbreaking to see that. In chapters 599 and on Kakashi discovers just who Obito actually is, which leaves him completely shocked to the point where Gai actually has to shake him back to the real world. Cue chapter 608, where he barely even tries to defend himself from Obito's attacks... The poor guy is completely out of it.
Can't leave Hiashi out either - beneath that icy demeanor is a man who will get on his knees to beg his nephew to reconcile with him.
Chapter 518 has Sai finally lose his ever-present control over his emotions and fly into a rage when Zombie!Deidara blows up Sai's zombified older brother, threatens to do it again and again after the guy reforms, and insults Sai's art.
Madara remained fairly cool and level-headed despite being in the middle of a massive war where his side consists of two people and a barely-controlled monster. Then Hashirama shows up and Madara slips into Blood Knight mode. He soon goes back to his normal personality, only for it to slip twice when he goes mad with power on being resurrected and then joy when realizing Guy is a Worthy Opponent.
Haguro Dou from Wolfen Crest is an unsmiling and absolutely gigantic middle-schooler who, as the violent son of a Yakuza boss, serves as werewolf protagonist Inugami's main enemy for the first arc. When Inugami shows him just how powerless he really is, Haguro starts busting out Slasher Smiles like nobody's business and goes on a psychopathic rampage that still shows no signs of stopping, all to regain his original image as a "monster."
In School Rumble's later chapters, we learn that Karasuma's lack of facial expressions was all an act. Once he does start showing emotions, he becomes almost unrecognizable.
Mai from Kanon is very much The Stoic at first, and seems pretty much emotionless up until the middle of her story arc. Sayuri gets attacked when Mai is not around, and Mai's reaction to this is absolutely heart-wrenching. She first collapses in shock at the sight of the wounded Sayuri. Once Sayuri is admitted to the hospital, Mai then tries to kill herself, feeling guilty for not having been able to protect her friend. When her suicide attempt is foiled by Yuuichi, she breaks down into tears.
And if at first you don't succeed...
In Code Geass C.C. is generally a rather stoic character, but the facade is broken when Lelouchcalls her real name and she smiles happily.
Paul in Pokémon normally has a scowl as his trademark expression with a condescending smirk or intense concentration thrown in during a few battles. The one time that he has ever flipped out completely is in A Pyramiding Rage! when he battled Brandon and Brandon kept knocking out his Pokemon with no sign of his even taking damage.
Nando the Pokemon minstrel, in his early appearances, was so calm and polite that even getting arrested and framed for robbery failed to rile him. Then came the Grand Festival, where when Zoey begins shutting down his combinations, he drops the facade and gets even more intense than she is.
Hun from The Legend of Thunder! likewise. Usually he remains calm and blah, including telling his partner to stop joking around. Then the fighting starts and he gets, shall we say, into it.
Van of GUN×SWORD has a sort of breakdown after facing a particularly powerful enemy. Not only does he show real fear for what may be the only time in the series, but the breakdown leads him to finally talk to his closest companion about his horrible past and his love for his dead fiancee. During this conversation, his voice shakes, his hand trembles, and he covers his face in a gesture more heart-wrenching than tears would have been.
Ai Emna of Hell Girl is usually the picture of stoic, bordering on being emotionless. Then the season one finale rolls around, when she confronts Hajime and his daughter about being descendants of the boy who betrayed her, and got her killed. Lets just say an angry Ai is something you definitely don't wanna meet.
Haku from Spirited Away is normally calm and emotionless, even when Yubaba was breathing fire inches away from his face and wrapping her hair around his neck and body. But when he is around Chihiro, he reveals many more emotions, such as concern, a hint of snarkiness and happiness.
Takayama from Witchblade kisses Masane after she visits him following his forced resignation from Doji.
The Major normally shoots once to incapacitate and kill, dealing with her missions calmly and coolly. At least, until she meets the guy who shot Togusa and damaged her body. Then she got scary.
Motoko: FORK OVER THAT GUN!
Shows in small pieces earlier, but in episode 8 of Puella Magi Madoka Magica Homura breaks down crying over how Madoka refuses to understand that others like her the way she is.
A lesser example, also from episode 10. Mami, who is second only to Homura in the stoic department, snaps into a sobbing mess when the Sayaka of that time line turns into a witch. She so breaks from the revelation that they'll all eventually become witches, that she shoots Kyoko's soul gem, killing her, and would have killed Homura too, had Madoka not killed her first.
Barnaby of Tiger & Bunny is normally a very restrained individual, but after the discovery and subsequent loss of a lead on the organization responsible for his parents' murder he completely loses it — physically attacking his partner Kotetsu, snapping at everyone who talks to him, and briefly going AWOL before his mentor manages to get a hold of him and calm him down. Likewise, any mention of his parents' killer makes him almost unrecognizable in his fury.
From episode 18 onwards the story is littered with such moments on Barnaby's part — so much so that it counts as a complete subversion of the Stoic Spectacles archetype he previously represented; the screaming in The Stinger of ep.18, a number of crying (nay, sobbing) scenes in ep. 19, and the Tender Tears in ep.s 20, 24 & 25.
Ken Washio on Science Ninja Team Gatchaman is extremely controlled. Except when it involves his father. Who was undercover for most of Ken's life. Then killed for real before the two could develop any sort of relationship. And angered Ken enough that he dragged the entire team into an enemy trap.
Guts is stoic to point of lacking emotions in Berserk, until he becomes a member of the Band of the Hawk. He finally begins to open up, but his emotions are mainly limited to mirth and anger, never showing anything tender. Then, during a touching scene when he and Casca make love, he breaks down completely and despairs over his abusive relationship with his stepfather. The following night, he has another Not So Stoic moment when he finds Griffith in the dungeon and sees the horrible suffering that had been inflicted on his friend.
Although Holo from Spice and Wolf may not seem stoic at first glance, her trickster and teasing antics cover serious issues. It's almost impossible to tell what she's really thinking... unless she's shocked into dropping her act, and as Lawrence quickly learns, what's she's usually thinking is something like "Please Don't Leave Me."
Erza from Fairy Tail has had quite a few moments, both comedic (the play episode) and dramatic (the Tower of Heaven arc, anyone?).
Kurama from Elfen Lied spends his early appearances as a professional, businessman, and Benevolent Boss. After chasing Lucy for a while, his facade breaks down, as she starts to destroy his life, dismembering his adopted daughter, and getting his biological daughter killed, and several members of his staff. By the end of this, his mind snaps, he grows a Beardof Sorrow, and lives disheveled in a hut on the beach with one of his hitmen. His mind continues to break down after seeing the dying clone of his biological daughter, and being taunted by Lucy over it. he eventually recovers.
The Agent is also a stoic character, hanging around in the background, and fighting off numerous Diicoloni while keeping a calm demeanor. She saves a scientist from an Army of them, and sacrifices herself to get her to safety. Once the scientist is gone, she begins crying, afraid to die, as the creatures advance towards her.
Vincent Nightray of Pandora Hearts usually manages to keep up his cheerful disposition quite flawlessly, even while torturing and killing people. The first time his facade slips, which is Played for Laughs, is when Adaintroduces him to herspecial collection. The second time is much more serious: Vincent confronts Duke Nightray after Elliot's death and loses his temper when the duke doesn't express any remorse over his son's death. Vincent beheads Duke Nightray along with his two bodyguards, thereby ending the legitimate Nightray bloodline. He Lampshades this trope when he comments that it isn't like him to lose control like this.
Louise of Zero no Tsukaima gets this during the rescuing of the Staff of Destruction in the first season. When Louise tries to defeat the giant golem and is more of a hindrance than anything what with her spells not doing any damage and Saito having to push her out of the way of an attack by the golem, Saito tries to get her to leave and run to safety, which she absolutely flat out refuses to do and tells Saito to let her continue, despite both of them knowing she's doing nothing to help. After a wake up slap, Saito tells her that her life isn't worth anything if she throws it away on pride, where upon Louise immediately breaks down and admits the reason she doesn't want to quit is because all the bullying due to the lack of talent and constant explosions from failed spells really has gotten to her deep down, and in reality she is outwardly tough but inwardly she's emotionally damaged from verbal bullying, name calling, and her own failings as a mage, and doesn't want to be labeled a coward on top of already being labeled as a no-talent mage, and even admits that in reality the name Louise The Zero "hurts (her) feelings" despite her visually brushing it off until this point. This doesn't change her personality in the slightest, however, but at least the audience has an explanation for some of it.
Haman Khan of Mobile Suit Gundam ZZ is normally made of lunar titanium. However, when Judau Ashta erupts into a Newtype-powered rage after his sister is shot, she completely loses her composure and runs for her life.
Kimi ni Todoke has an example in Ryu: in a flashback to his mother's death, little Chizu starts to bring him onigori as his mother used to make. When he finds her leaving it on the doorstep, both of them break down crying. He was only around eight years old at the time, but it's still a shock, and very heartwrenching.
Word of god says this is mostly out of relief that she's been exposed and can briefly be a normal teenage girl.
Levi is visibly effected by the death of his squad.
Bertholdt even after The Reveal seems to hold himself together much better than the other two spies, but it all comes crashing down when he's confronted by his former team mates and breaks down crying, because he truly feels horrible about what he's done and really did see them as his friends.
In K, Kuroh is usually The Stoic when compared to Shiro, but he gets agitated a few times. A good example is when Shiro procrastinates on proving his innocence, or when he calls Kuroh his wife. The only time his calm facade really derails, though, is at the end of episode 3 when he shows off his tape recorder, which has all of his old master's quotes on it. He gets a big smile, giddy fanboy sparkles, and a Luminescent Blush.
An even better example is Munakata, who spends basically the entire show cool and unruffled, even when he's in combat...until Mikoto pisses him off one too many times and Munakata shoves him to the ground in a rage. He also makes a heartbreaking face when he realizes he has to kill Mikoto.
In InuYasha there is actually an episode entitled "InuYasha Show his Tears for the First Time" in which the title character believes his friends are dead and almost breaks down. He fully starts crying in relief when he finds out they survived.
Later in the Final Act, InuYasha cries again, this time in grief when Kikyo dies in his arms
Also could count in Sailor Moon when the typically hardass Sailor Uranus witnesses her lover, Sailor Neptune get her heart stolen and die in front of her, while Uranus doesn't break down or cry, for the first time in the series she looks truly heart broken. She then attempts to kill herself. (Whether that action was performed due to anguish and desire to follow her girlfriend into death, or purely for the sake of the mission is never fully clarified
Crown Prince Kouen in Magi - Labyrinth of Magic is normally very emotionless, even when his stepmother Gyokuen flirted aggressively with him, when Gyokuen succeeded his father before him and when half of his body was burned away by the Medium. However, he would occasionally show emotions such as getting angry, chuckling and laughing at Alibaba.
Batman's biggest weak points as far as emotion goes are his children, but especially Dick. At one point, when exposed to the Scarecrow's fear toxin, he runs through his worst fears checklist in an almost bored manner, with everyone close to him dying. Then it comes to Dick, and Batman's only response is a very determined "No."
In one instance, Batman was talking with Catwoman after the Gang War storyline, which devastated the city and left two of his allies dead. Angry at his casual reaction to it, Catwoman starts holding him, yelling "Feel! Feel something, damn it!". Bruce just pulls her into a hug and says "Selina... I feel everything". Not a big show of emotion, but it certainly illustrates the point.
In "Mad Love", Batman apparently bursts out in hysterical laughter at the thought of Harley Quinn actually winning the love of the Joker. In this case, he was deliberately doing it to play on Harley's insecurities. It worked, too.
In The Killing Joke, he genuinely guffaws with The Joker about a metaphorical joke about the two of them. It's more a laughter of the damned, but it's still real laughter.
The Trope Image is from Knightfall, just after Batman's forced to be stopped from smashing Zsasz's head in like a watermelon. The kicker? That was part 3. It gets worse from there.
Mr Freeze is usually very grim and without empathy. However, bring up his beloved Nora and he will breakdown, either in rage or sorrow. Depends on the writer, as some write Freeze to be more openly emotional to the point where the trope wouldn't apply.
Desire in The Sandman just seems amused most of the time. Even when its plans fail, it just shrugs it off. The exception: getting one-upped by Dream during "Three Septembers and a January", when Joshua Norton rejects its offer out of hand. It's the only time Desire gets angry.
When Morpheus himself get confronted by the insane Hector Hall and learns that he calls himself "The Sandman", it's the first and only time on the whole series that he laughs (although his head is hidden behind his helmet at the time).
In "Brief lives" Morpheus is visibly upset after killing his son and sheds few tears while looking through his memories in his chambers.
James-Michael is The Stoic in Omega The Unknown due to having been raised by robots, but begins to react more emotionally as time goes on, even shedding a tear when one of his friends is beaten to death by bullies, though in truth he's more enraged than sad.
Cyclops has done this a few times, notably in the X-Men First Class two parter Catalyst. As everyone wakes up to find their powers are gone, they feel either intrigued, shocked, or depressed; Scott however is dancing with joy, happier than ever before as he can finally open his eyes without killing everything. Then when they regain their powers they're ten times stronger, with Scott now having full control. However, Xavier realizes they have to give up their new level of power because its making them too God like, Scott is the only one who isn't now a physical God, but willingly gives it up, but not after a panel or two of looking like hell.
After Zonic in Archie Comics' Sonic the Hedgehog makes Sonic kill an alternate version of his father and Sonic blows up at him, Zonic reminds him that the version was technically his father too.
The Transformers IDW: Cyclonus is fiercly loyal to Galvatron, and always follows him with a dour attitude. However, when Galvatron is beaten back, Cyclonus is free of his influence (not mind control), and attacks him screaming about how Galvatron was destroying their home. This continues into Transformers: More than Meets the Eye: where he's with the Autobots and very closed off, even his threats are delivered quietly and with a straight face. His interactions with Tailgate have caused him anger, and even violence, though he softens eventually, and shows him a kinder side.
Soundwave from the IDW comics barely even registers emotion, he's composed in battle, and barely reacts when he's almost lobotomized. When Thunderwing's release is threatened, he considers the plan insane and tries to stop it, all the while never betraying his feelings. His emotions have only surfaced roughly three times once in Monstrosity when sharing a jab at Scorponok's expense, once during AHM where he wordlessly screams when he finds Rumble near death, and finally during the Remain in the light arc when Ravage starts dying from the Depopulation Bomb, he's in a full panic and asking for someone to save him.
X-23 as a rule keeps her emotions tightly controlled, and it's a significant character trait she has difficulties expressing, or even understanding, what she's feeling. She endures the years of physical and emotional abuse inflicted on her by Zander Rice and Kimura in complete silence, even when her creator/mother, Sarah, tries to get her to talk about it. At least until she's forced to kill Sarah by the Trigger Scent during their escape from the Facility, at which point for a couple pages Laura becomes a lonely, broken girl desperately crying over her mother's body to come back to her. She also breaks down in tears once again when she's forced to cut off ties with her cousin and aunt to protect them form Kimura. The only other times she generally lets her guard down is when someone she cares about is in danger. In which case it's a very, very bad idea to be on the receiving end.
The New52 version of Superboy, when he starts getting a no-holds-barred beatdown in issue #2.
The interrogator of all people in You Obey is like this. Because the story is told from his perspective, you get a very vivd idea of what his job does to him.
Suyou in Kyon Big Damn Hero shows satisfaction when Kyon takes one of the reprogrammed Morph Weapons from her. She also wishes him good luck, which he promptly needs.
Halo: Finishing The Fight The Chief stays the same calm, composed soldier for the entire story, even when facing legions and Orcs, Dark Elves, Demons and even the Demogorgan. But after he has finally killed the Demogorgan thanks to Cortana's Heroic Sacrifice, this happens:
He grit his teeth again, and redoubled his efforts to keep moving. Cortana had bought this victory with her life. He silently swore to make that sacrifice count for something beyond what it already had. Right arm out, dig in a bit, pull, repeat. He chanted the mantra over and over again in his mind as he slowly dragged himself towards the faint, now blurring, light ahead. He attributed the blurring to more malfunctions and failing systems, never realizing that the cause was the tears filling his eyes.
Snape in Arc Of Sacrifices, big time. After being his usual snarky-git self for pretty much the entire series, he goes absolutely insane when Regulus Black dies in the seventh book.
This occurs in Clouded Sky with Igneous, the protagonist's normally very stoic Magmar. During a Pokémon battle, an enemy Girafarig forces him to accidentally injure one of his allies and, due to his constant fear of unintentionally hurting those close to him, he flies into a rage and starts mercilessly pummeling Girafarig, completely ignoring his trainer's commands.
In the fanfic Retribution, Spock actually shouts when Kirk contradicts his statement that the captain "[has] no idea of the offenses that can be committed between us." Justified as the painfulness of McCoy's cure for Rapid Aging sapped his self-control.
Like the previous two examples, Brainiac from Mare of Steel gets visibly angry when Rainbow Dash/Supermare breaks out of his Sadistic Choice and decides to just kill her instead of collecting any information from her.
Star Trek VI: The Undiscovered Country. When the killer turns out to be a protege of Spock's, he smashes the phaser out of her hand in a brief burst of anger after she refuses to shoot him. The feelings of pain and betrayal are written all over Spock's face.
There's also the fact that she refuses to do the logical action and kill him.
...And even then, he's still pretty composed. It's not until Kirk says he didn't love his now-dead mother that he shows emotionFLIPS HIS SHIT
An indirect example, but after the same events mentioned above Old Spock as part of a mind meld, transfers his emotions to Kirk. Kirk, tears streaming down his face, says, "You do feel."
Matt King in The Descendants is usually completely stoic, especially around his kids. It makes the few moments when he breaks and finally gets angry or cries extremely effective.
In Bridge to Terabithia (the Film of the Book), Mrs. Meyer is the typical Stern Teacher, very uptight and severe. She breaks into sobs while she explains to Jess and that she understands how he feels because of Leslie's death since she had a very harsh time after her husband's death.
In Inglourious Basterds, Nazi colonel Hans Landa has a cordial talk with a French farmer about the Jews he's hunting. The farmer is hiding said Jews beneath his floorboards, but keeps up an impenetrable poker face throughout, until Landa reveals that he already knows about them, at which point tears start streaming down the poor man's face.
Even then his voice never wavers. He just looks utterly haunted as he continues to levelly answer Landa's questions.
Another, slightly moredisturbing example is Landa himself. Throughout most of the movie, he is Affably Evil, almost never wavering in his soft-spoken cordiality...until he calls out Von Hammersmark on being a spy for the Allies, then strangles her to death.
And then becomes a traitor himself, which makes his murder of the actress a little strange.
Landa has another NSS moment at the end when Aldo Raine shoots the German soldiers they were escorting along with him. It was most likely the shock of the unexpected gunshots giving way to fear with the dawning realization that, with his only two compatriots now freshly killed and bleeding out on the ground beside him, and with his hands bound and his only company the remaining Basterds...he's well and truly fucked.
In the Sherlock Holmes vs Jack the Ripper movie, Murder By Decree. In it Holmes (played by Christopher Plummer), who remains characteristically Stoic after watching the first four corpses the Ripper leaves behind, starts to show signs of this when he sees what the Ripper did to Mary Kelly, whom he swore to protect moments before her death and finally breaks down in front of Watson over the realization that even though he has figured it all out, the cold bastards behind it will never be punished and all the people they have wronged will keep suffering.
Forms part of the plot of The Invisible: Nick resented his mother's stoicism, especially after his father died, thinking she had no actual feelings. While he's missing and presumed dead, he finds her still keeping the facade and rants furiously (and uselessly) at her. She can't see or hear him. Then she upsets a teacup, and abruptly breaks down sobbing...
Harmonica in Once Upon a Time in the West remains calm for the most part, and even when he is annoyed it comes off as mild. But he's crying in the flashback of his brother's death.
Zus Belieski in Defiance is a cold hearted bastard. When his younger brother was sobbing helplessly over the recent deaths of their parents, Zus shook him roughly and shouted at him to stop crying. The one heartwrenching moment when his armor cracks comes after he learns that the wife and son he'd left in a then-safe city had been killed by the Germans.
The famous scene from Schindler's List when Oskar Schindler breaks down in front of all of the Jews that he saved. As the Tear Jerker page will attest, many tropers found this moment to be more than they could bear.
Éomer in the Lord of the Rings films is a mix between The Stoic and The Berserker, depending on whether he's in battle or not. But in the extended edition of Return of the King, when he finds Théoden dead and Éowyn nearly dead, he runs over to them screaming wordlessly in horror and grief. It's so at odds with his normal persona that it's actually quite effective.
Legolas reacts to most things with Dull Surprise. Orcs? No problem at all. Oliphaunt? He's a bit awestruck by the sight of it but he brings it down anyway. The Balrog turns up? He's not just scared, he's absolutely flat terrified.
Thorin in The Hobbit has lost his cool a few times. During the stone giants' battle, he started frantically calling his nephew's name when he believed Fíli had died. And after Bilbo saved him from Azog and his orc mook, he furiously yelled at the latter for putting himself in danger before pulling Bilbo into a hug.
Dredd Dredd drops his usually unflappable demeanor when he's faced with rotary cannons, and runs like hell. Though, being Dredd, he still manages to flee in a fairly composed (given the situation!) and manly way.
Dredd: Oh, shit.
In Star Trek Into Darkness, Spock makes it clear to Kirk and Uhura early on that he does feel; it is a conscious effort of his to not feel fear, doubt, etc. His control of his emotions wears down over the course of the film, culminating with him not being able to contain himself when he and Kirk are having (what he thinks is) their last conversation then completely losing it when Kirk dies and Khan is still alive.
The deadpan and goth Claire Wheeler plays up the contrast with her Large Ham partner Buck. But when Ozma Kappa wins the Scare Games, she goes nuts with excitement, even more than Buck.
Dean Hardscrabble is very strict, harsh and unflappable. When Mike and Sulley create a scream of such power that it not only activates a door from the human side, it fills up every canister in the laboratory until the door explodes, she becomes wide-eyed in shock. After expelling them for destroying the lab, she wishes them good luck and informs them she believes in them because they did one thing she thought was impossible, and that was surprising her.
Marshall Pentecost raises his voice three times in Pacific Rim: first to shut up Hermann after Newt Drifts, then a short moment while chewing out Raleigh (before going back to his calm), and finally, raising his voice for the Rousing Speech.
Die Hard: With a Vengeance has two female examples:
Action Girl Connie Kowalski is pretty hard-boiled - as are almost all of the NYPD cops - but during the evacuation of the elementary school (when it's believed that a bomb has been planted there) she confesses that she might "pee [her] pants."
Katya, Simon Gruber's Dark Action Girl, never smiles, never speaks, never even makes a sound throughout all her scenes...until the film's climax, when she and Simon are interrupted by John McClane and Zeus Carver at a very inopportune moment - and she completely loses her cool, firing off a machine gun and screaming in rage.
In Godzilla (2014), when he sees the dead body of his father, Ford tears up.
In Serenity, when The Operative realises who Mal has brought with him to get past the blockade, he drops the calm, soft-spoken demeanor that he has exhibited throughout the movie and screams in terror:
Operative: Target the Reavers! Target the Reavers! Target everything!SOMEBODY FIRE!
"Curious George Goes to the Hospital": A sad little girl, hospitalized for the first time with an undisclosed illness, is very stoic ... until George snaps her out of her depression with his antics. At first, it is gradual ... but the real breakthrough comes near the end of the story, when George takes another young boy's wheelchair for a wild ride. (The boy, whose leg had been broken in a car accident, was undergoing physical therapy when George decides to take the wheelchair for a ride.)
Sherlock Holmes, when Watson is wounded in the story The Three Garridebs — one of the most touching moments in the entire canon. Not just his childishly irrational plea (he does not ask Watson if or where he is hurt, but frantically begs him to not be hurt, while invoking the name of God while he's at it), but even more strikingly, his physical description depicts him to be on the verge of tears. Watson's narration serves to only heighten how incongruous and startling it was even for him to see Holmes in such a state.
In China Miéville's The Scar, sequel to Perdido Street Station, the main character Bellis hardly ever shows any outward emotion, except for the scene where she suddenly breaks down and starts crying upon the realization that she won't be able to get a message to her home warning them of an invasion, much less be able to return there. The character who discovers her breakdown is completely stunned.
The only time in Haruhi Suzumiya when Yuki Nagato showed a significant emotion was in the Alternate Universe she created, where she was a normal girl. She gave a definite smile to Kyon, which dazzled him quite a bit.
One of Dan Abnett's contributions, Know No Fear, had the otherwise controlled Roboute Guilliman react to Lorgar's betrayal with fury, vowing to rip the Word Bearers primarch apart and throw the pieces into hell.
In the second book of the Artemis Fowl series, the usually stoic protagonist has a small emotional breakdown after hearing that his father is still alive.
In James Swallow's novel Deus Encarmine, Arkio accuses his dispirited companions of being afraid. Producing a moment where they confess, passionately, to their fear: they had seen most of their comrades attacked by witchery and turned into berserkers who had fallen on each other and perished miserably. Sachiel tries to rebuke them — it had been a honor to die for the Emperor - but Arkio agrees — what would they be, to see that and feel nothing?
Sense and Sensibility: Elinor Dashwood is calm, sensible, and levelheaded no matter what turmoil is going on in her personal life — until Edward informs her that no, he did not marry Lucy Steele, and would really quite like to marry her, thank you very much. At which point she loses it. Spectacularly. See Hattie Morahan in the 2008 version or Emma Thompson in the 1995 version to see how it's done.
Happens to Griboyedov in The Death of the Vazir Mukhtar, as he does sometimes confide some of his many worries and anxieties to particularly close friends.
Harry Potter: Severus Snape has four during the series: When Sirius whom Snape believes betrayed Lily to Voldemort escapes, when Harry accidentally dives into his memories, "DON'T CALL ME COWARD!", and his reaction to the news of Lily's death. Other than that, he's just another teacher with a sadistic slant.
"Give me a reason to do it, Black. Give me a reason and I swear I will."
Oh, and one other occasion.
Dumbledore: "After all this time?"
The main shtick of Professor McGonagall, who spends most of her time being a stoic Stern Teacher and the rest weeping unashamedly.
Or gleefully egging on Peeves, the poltergeist, in his quest to make Umbridge's life hell (though she does try to hide it from the students). Or yelling apoplectically at the students who tried to sabotage her house's Quidditch team players (which she doesn't try to hide at all).
Zal of Quantum Gravity. He is completely cool in battle situations, and can keep that together for as long as he needs to...usually. Then he hears that/how Dar died and can't keep it together.
In The Westing Game, Judge J.J. Ford consciously decided to stop smiling when she began her law career, the better to maintain a serious, dignified demeanor, conserving her upbeat facial expressions for when they were really needed. It worked, too: she's so good at appearing as The Stoic that when she realizes a mistake she's made and starts chiding herself aloud, everyone present is shocked at this out-of-character display of emotion.
For all his iron-self-control, he was near bursting with long pent-up shame, hate and rage, ready to take any sort of a desperate chance.
Jane Eyre wasn't stoic as a child, but by the time she gets to Thornfield she is pretty emotionally reserved until Rochester threatens to send her away to Ireland once he has married Blanche Ingram. In fact, Rochester is trying to elicit this trope from Jane.
In World War Z, Todd Wainios tells a story about one of the biggest badasses on his team (an enormous ex-pro-wrestler who once used a zombie to beat other zombies into non-existence) be reduced to an inconsolable sobbing heap by the scent of cheap perfume on the wind.
Aaron in The Fire's Stone by Tanya Huff. He's so scarred by his lover's death that he forces himself to feel nothing. It's not until the last third of the novel that he finally breaks down and cries.
Dally from The Outsiders hardly cares about anyone or anything. But when Johnny dies, he visibly loses it.
Hoole, in Galaxy of Fear, is profoundly affected seeing the wraiths on Kiva - he, who would always shapeshift to vigorously defend himself and protect his charges, went to his own form, fell to his knees, and covered his face. He held himself responsible for what killed them.
In Redeeming Love, the heroine is a cynical Broken Bird who regularly tends to shrug off (or laugh off) both physical and emotional trauma (and romantic overtures from her Love Martyr husband that would have many other women melting into goo at his feet). Before it wears off entirely, her façade splinters twice: once, when she simultaneously realizes that she does care about Michael and yet thinks she isn’t worthy of his love, and again when she experiences real lovemaking for the first time (in contrast to thirteen unhappy years as a prostitute) and finds herself weeping as she’s coming down from her climax.
Legacy of the Dragokin: Lydia normally acts like she's the same age as her grandfather but has an emotional outburst when Benji awakens his dragokin powers. She cheers him on in a manner normal for a fifteen year old and everyone looks at her in shock. She blushes and then she repeats herself in a more subdued and grown up manner.
Demandred of The Wheel of Time is a villain so consumed with hate for the Dragon (Lews Therin Telamon or his reincarnation Rand al'Thor, he doesn't care) that most people who know him have only seen him show one emotion- cold-blooded determination to see the Dragon dead, no matter the cost. It's explicitly noted that he never laughs or so much as smiles. Then, during the final battle in the last book, Demandred finally thinks victory is in his grasp, and he basically rampages around the battlefield wielding a massively powerful sa'angreal, effortlessly destroying almost everyone in his way, bellowing at the top of his lungs for Rand to come and face him while describing all the horrible things he'll do if Rand fails to show, and generally being the Large HamHero Killer he was born to be. Not unexpected when you keep hate locked up inside you for centuries and finally have the chance to let it out.
Dallas: The Season 7 episode "Swan Song" was supposed to be Patrick Duffy's swan song in the series, for good, when Bobby Ewing is struck by a speeding car (driven by the homicial maniac Katherine Wentworth). At the hospital – in one of the cheesiest-in-retrospect "death scenes" in TV history – the entire cast is in tears ... including Bobby's older brother, that monster J.R.! (Incidentally, tears are seen rolling down J.R.'s cheek, but otherwise shows very little emotion in the final scene, where everyone is gathered around Bobby's bedside as he mumbles his final words.)
The Dukes of Hazzard: Despite their villianous ways, Boss Hogg grows geniunely worried every time Lulu or even his avowed enemies from the Duke family are in serious trouble. However, Rosco has outright cried when Boss, the Duke boys or his beloved basset hound Flash were in trouble. (Rosco's emotions are spelled out perfectly in the Season 2 episode "Granny Annie" and the final episode, "Opening Night at the Boar's Nest" – both times, when Boss was in serious trouble and the villians had every intent to kill him.)
The Twilight Zone: The opening episode of the 1985 revival, "A Little Peace and Quiet," during the climactic scene — nuclear war breaking out between the United States and the Soviet Union — features a newscaster trying to keep his emotions in check as he reads an EBS alert live over the air, but his voice is trembling as the threat of the missiles becomes more imminent. (For instance, the alert is supposed to provide instructions of going to the nearest shelter, but he says, "What's the point? It's over! We're finished!" A few seconds later, he begins trembling when he notes that "Soviet missiles have entered U.S. airspace."
Spock again in "The Naked Time", although that was the result of a strange phenomenon. At least he was able to duck into a room before he fell to pieces.
Vulcans developed their culture of tightly controlled emotions to deal with the fact that they are really very emotional, and without strict discipline, they tend to overreact to everything. Indeed, before Surak proposed his philosophy of strict self-control, Vulcan society was about to completely destroy itself. Under sufficiently extreme circumstances, a Vulcan's self control can be broken (usually only temporarily), and everyone around will be reminded that under that stern calm face lies a turbulent sea of emotions that would drive the less-disciplined completely mad.
They also get really violent and horny during Pon Farr, basically Vulcans in heat. Also, Spock is only half-Vulcan, as his mother was human.
If you want to imagine what Vulcans would be like if they gave into their emotions, one need look no further than the the highly paranoid and extremely dangerous Romulan Empire, which spawned at least one planet-destroying and truly Axe Crazy psychopath, Nero.
Vulcans and Romulans being much stronger than the average human does not help matters either. Kirk has had to provoke Spock into an emotional display in both the original series and the new movie continuity, and both times Spock nearly killed him. Even Khan is no match for a pissed-off Spock in a straight-up fistfight, and he knows it, running away as soon as Spock shows up.
Star Trek: The Next Generation. Data's lack of emotion is a frequent plot point in the series. With a few notable exceptions. One episode where he was almost driven to murder (and then lied about it to his commanding officer) and again when manipulated by his more emotional brother, causing him to kill a Borg drone in rage. Even he seems rather bewildered by this just afterward: "I got angry."
One of the subplots of Generations is Data deciding to reinstall the emotion chip given to him in the above episode, and dealing with the resulting outbursts. At the end, he discovers that his pet cat is still alive and begins to cry, which he assumes must be a malfunction of the chip. Troi assures him with a smile that "it's working just fine."
The episode "Sarek" dealt with this with the eponymous character (Spock's father, of course), whose emotional control was breaking down due to a rare illness. Determined to finish his last mission, he melds with Picard, who is normally very emotionally controlled in his own right, allowing Sarek to be himself again long enough to finish the negotiations. But we also see the effects of Sarek's illness in Picard during the meld in what can arguably be described as a Crowning Moment Of Heartbreaking.
Part of the effects of the mind meld with Picard are to subject an unprepared human mind to the powerful raw emotions of a Vulcan. Having not been raised from birth to learn to control those emotions, Picard spends the duration of the experience practically rabid, suggesting what pre-Surak Vulcans were like.
Look at Sarek in The Search for Spock. He's downright pissed off when he thinks Kirk has Spock's katra and screwed up by leaving Spock's body on Genesis. He's so overtly emotional it seems to surprise Kirk quite a bit.
Picard has his moments as well, particularly in "Family", Generations and First Contact. "Chain of Command, Part II" could be a case of Breaking The Stoic.
Teal'c: If you are to die, Daniel Jackson, I wish you to know that I believe that the fight against the Goa'uld will have lost one of its greatest warriors. And I will have lost one of my greatest friends.
Even better when you realize it also illustrates his Character Development. He gives Daniel one of the highest compliments he can both in his own culture ("one of its greatest warriors") and in his adopted one ("one of my greatest friends").
And it continues into the next episode with this exchange:
Carter: We were a team, Teal'c. No one can even begin to understand what we went through together, what we mean to each other. So maybe Daniel has achieved something of great cosmic significance, I don't know. And to be honest with you, right now, I don't really care. I'd rather have him back. Teal'c: [with obvious emotion] As would I.
It is very subtle, but in "Cor-Ai", when Teal'c and Jack are arguing over whether or not he should defend himself while being tried for the many horrible things he did for the Goa'uld, you can see Teal'c's jaw trembling with suppressed anger at himself.
Teal'c's facade actually cracks a little in the very first episode. O'Neill sees that Teal'c is struggling to carry out the vicious acts demanded of him by the Goa'uld. This prompts O'Neill to seeks Teal'c's help in escaping, and kicks off the rest of the show.
Antony: You won't turn to drink will you? You stoic types often do when disappointed in life.
Averted as Vorenus is the only one who does not turn to debauchery in the Egyptian Palace and stays a true Roman.
Dexter very rarely shows emotion, genuine or otherwise. This makes the very rare outburst all the more interesting.
Particularly shocking was in the Season 5 premiere, when while grieving Rita's murder, he flies into a rage and savagely beats a man to death in a restroom. Much like the example with Vulcans in Star Trek, this is a small glimpse into what he would be like without the careful control provided by the Harry Code.
In The Sarah Connor Chronicles, Cameron is almost always an emotionless and cold machines, except in a very few select moments where she does show hints of anger or fear. In particular, one scene in the episode "Mr. Ferguson Is Ill Today" shows her moving through a police station, frantically (in a disturbingly calm way) looking for John, or her pleading for her life in "Samson & Delilah".
And then it gets completely flipped in "Allison From Palmdale," where she is shown crying, acting terrified, and in one scene being very angry, very calmly.
Then there's Derek, Deadpan Snarker and seen-it-all cynic. Stone cold, to the point of having more in common with a machine like Cameron than either would be comfortable to admit. ...And then moved to Manly Tears at the sight of her doing ballet by herself.
Takeru of Samurai Sentai Shinkenger has such a moment in episode 18, when he's reunited with his old friend, Genta, and has to step out of the room to make sure his "retainers" can't see him when he starts cracking up at Genta's antics.
Taken has Jacob, a quiet, bookish kid with incredible psychic powers. He reacts to everything, from being kidnapped to being bullied with calm logic. When he has to live away from his mother, he breaks down crying.
Juliet Burke from LOST, originally of the Others, was first seen as having a cold and expressionless demeanor and carried out her orders from Ben. She even aimed a gun at Kate's head when Sawyer didn't do what she asked. Sawyer commented that she would have actually shot Kate "No problem." Then another one of the Others was shot and Juliet rushed to save her life with Jack, which sparked her Not So Stoic persona. Juliet panicked the whole time when she and Jack were removing the bullet and trying to stitch her up. When they failed in saving her, Juliet broke down in tears and explained that being a fertility doctor she still hasn't gotten used to death. Which, based off her flashbacks of her work with the Others, is quite surprising.
Actually it has been shown that any time Juliet deals with death or her sister she gets very emotional. The rest of the time she's the token Stoic.
This comes to define her in the end of Season 5. Throughout the finale, she acts as though she has a strategy in place regarding the Jughead and the Island, until she breaks down completely and confesses that she's only going along with Jack's plan because she can't bear to lose Sawyer.
Farscape: Aeryn Sun, though originally The Stoic on Moya, gradually moves away from this as her relationship with Crichton blossoms. When she and Crichton are fighting for whatever reason, she usually reverts to The Stoic as a defense mechanism.
In an episode, this gets flipped, when they are on break from their relationship. Crichton seemingly takes something that Noranti gives him for pain and is very cold and uncaring towards Aeryn, while she is the one who is pleading with him. It turns out to be an act to prevent Scorpius from using Aeryn against him. It fails.
Scorpius himself has a few of these moments, most of them revealing that he has a downright vicious temper underneath his cool, calm exterior.
After JT is Killed Off for Real on Degrassi The Next Generation, the usually stoic Liberty is in shock at first and Mia even calls her a robot because she had yet to shed any tears. She finally breaks down at the school's memorial service for JT (which just happened to be right after she learned that he still had feelings for her and was on his way to tell her when he was killed).
In the BBC mini-series, Sherlock, the title character is never shaken in the face of violent crime - up to and including murder - but has a general tendency to lose his cool when someone he is fond of is being seriously threatened — notably, Parental Substitute Mrs Hudson and Only Friend John.
Molly: You remind me of my father [...] He always pretended like everything was fine, but whenever he thought nobody could see him, he'd look really sad. You look sad...when you think he [John] can't see you.
While not exactly stoic per se, Joel of Mystery Science Theater 3000 always took his captivity with a certain laid back good-naturedness. "Manos" The Hands of Fate was one of the very few movies that made him noticeably angry, to the point of him snapping at the screen.
Joel: DO SOMETHING!!
Aaron Hotchner of Criminal Minds is usually the embodiment of stoicism, which make the events of the episode "100" all the more heart-wrenching.
Prince Arthur from Merlin is quite good at keeping his cool, save on two occasions: once when he learnt the truth about his mother's death (his father was responsible) and again when his father sentences his beloved Guinvere to be burnt at the stake.
Temperance "Bones" Brennan is sometimes accused of being an Ice Queen, due to her emotionally distant manner and lack of social skills. When Tempe loses it, you get to see the Broken Bird inside.
In one of the early episodes her uncaring attitude was being used against her in a court case. Booth had the attorney bring up her vanished parents in order to show this trope to the jury.
Brennan: How I feel doesn't matter. My job doesn't depend on it.
Levitt: But it's informed by it. Or are you as cold and unfeeling as you seem?
Brennan: [in a raw emotional tone] I see a face on every skull. I can look at their bones and tell you how they walked, where they hurt. Maggie Schilling is real to me. The pain she suffered was real. Her hip was being eaten away by infection from lying on her side. Sure, like Dr. Stires said, the disease could contribute to that if you take it out of context; but you can’t break Maggie Schilling down into little pieces. She was a whole person who fought to free herself. Her wrists were broken from struggling against the handcuffs. The bones in her ankles were ground together because her feet were tied. And her side, her hip and her shoulder were being eaten away by infection. And the more she struggled, the more pain she was in. So they gave her those drugs to keep her quiet. They gave her so much it killed her. These facts can't be ignored or dismissed because you think I'm boring or obnoxious, because I don't matter. What I feel doesn’t matter. Only she matters; only Maggie.
It's especially jarring in an episode where she begins to associate herself with a dead woman who was, like her, a loner with no friends outside of work and a Love Interest she spurned. She even keeps hearing the woman's recorded voice as her own and seeing herself in all the pictures of the victim. She realizes that she has screwed up her one chance to be happy with Booth. This episode is all about her stoicism slowly slipping.
Interestingly played with in the season 7 finale when Brennan is being framed for the murder of the victim of the week. Brennan remains hyper-logical throughout, while other characters fall apart. It's pretty predictable that Booth and Angela will get emotional, but when Cam starts crying because she doesn't want to turn over evidence that will get Brennan arrested, you know the situation is serious.
The X-Files' Scully was always portrayed as the stoic, especially compared to Mulder, who freely showed his feelings and wasn't afraid to cry. Very few times does she break down, until season 8. She is pregnant and alone, Mulder having been abducted by aliens. Add to that the fact that she is reassigned to an agent who thinks Mulder is insane and for the life of him cannot see that Mulder and Scully were so much more than work partners, having to train said partner, having to head a taskforce to find Mulder pretty much on her own, then finding Mulder dead and having to bury him, having him come back to life and be distant from her, it was pretty much a stress-filled, non-stoic season for Scully. And never was there anyone more entitled to break down.
Buffy the Vampire Slayer's Oz is famed for his utter lack of emotional response to pretty much any intense situation, reacting to both realizing he's a werewolf and finding a submarine on his doorstep with a mere "huh". Push him over the edge, though, and things will get broken. Or beaten up. Or possibly killed. For most seasons, this Berserk Button consisted of Willow—either seeing her threatened, hurt or faced with the prospect of losing her. And after he did lose her, there were tears. Both times. Later on this focus shifts to his wife and son.
In The Wire's later seasons, Marlo Stanfield is the ruthless kingpin of the entire Baltimore drug market. He and his team kill people at whim and 'disappear' them, hiding the bodies in disused vacants, so as to avoid police attention. Marlo is completely professional at all times - even when he and his team have been arrested and he faces a lengthy prison term he barely seems to care. However, when he learns that a stick-up artist has been insulting and challenging Marlo on the street, he shows true emotion for the first time in the series. "My name is my name!"
He shows emotion for the second, and final time, in his last ever scene. After taking back a corner single-handedly, he expresses genuine happiness.
NCIS: Los Angeles: Hetty and Callen are normally very cool and collected. Then Callen notices an alarming trend of Hetty recruiting lonely orphans and training them to be lonely operatives. He gets increasingly agitated when he confronts her about it. They end the conversation shouting and near tears.
Callen: How many were there?
Hetty: [quietly] This conversation is over.
Callen: How many?
Hetty: [exploding] A LOT! [Pause. She fights tears. More quietly] There were . . . a lot. Is that what you wanted to hear?
JAG: Sarah MacKenzie is mostly portrayed, as part of the Marine persona, as The Stoic. However, in "Second Sights" when finding her estranged father on his deathbed and in a coma at a hospice, and at the same time meeting her even-more-estranged self-centred white trash mom, she turns out to be Not So Stoic. But it turns out to be a Double Subversion: after her father has passed away, Mac tells her mother stoically that she never wants to see her again - because it was she, not her father, who once abandoned her.
Doc Martin: Martin after hearing the news about Joan's death. Despite outwardly remaining his typical aloof self, as he walks around her empty house, his eyes betray how utterly heartbroken he is.
Randy Travis' "A Man Ain't Made of Stone" is about a man who thinks that he's all tough and stoic… until she leaves and he realizes that yeah, he's not so stoic after all ("Sometimes all it takes is facing the night alone / And that's when you know / A man ain't made of stone").
On the WWF Monday Night Raw episode following Owen Hart's death in May 1999, several of the normally ranting, raving, dastardly villians were offering genuine, heartfelt thoughts and condolances to the Hart family ... many of them through very real tears.
Hulk Hogan was shown on very rare occasion to get emotional (in kayfabe), the most notable experience being on the February 3, 1989 episode of The Main Event, where Hogan and Randy Savage were facing the Twin Towers (Akeem and Big Bossman) in a tag team match. Midway through the match, Akeem threw Savage onto his beautiful valet, Miss Elizabeth, and Elizabeth crumpled to the floor in an unconscious heap. Hogan immediately ran to Liz's side (as a woozy Savage struggled to regain his bearings) and immediately lost his composure. In tears, he cried, fearing that Elizabeth had been killed ... or worse! Hogan's decision to leave Savage at ringside and instead be at Elizabeth's bedside (prepared for when the medic would give the official word that Elizabeth was ... DUM-DUH-DAAAA!!! ... DEAD!!!) ... set off a series of events later in the match that led to Savage turning on Hogan and a match set up for WrestleMania V, in which Hogan defeated Savage to reclaim the World Heavyweight Championship.
At the end of Sherlock Holmes, Holmes, after having replied indifferently to Alice's asking whether he cares for her at all, takes her hand gently, confesses that he does care for her, and is finally moved to embrace her protectively.
Toa of Ice characters from BIONICLE tend to be both the quiet ones and stoic, until Character Development kicks in, the most famous example being Kopaka. When not making all sorts of nasty, sarcastic remarks to people that annoy him (as in, people who express emotions freely), he keeps his thoughts to himself, and would like to finish his duties as quickly as possible. But when his friend Pohatu recovered from a Disney Death, he softened up quite a bit. Later, in another story, after having been beaten, weakened and looted, a group of innocent villagers mistook him and his team for a bunch of villains, and attacked them. This angered Kopaka so much that he lashed out with what little power he had left, with the intention of killing the villagers!
Jon Irenicus in Baldur's Gate II remains stoic for most of the plot, at most displaying a kind of icy annoyance... Until a scene right before the end when he finally cracks.
Jon Irenicus: "Once my lust for power was everything but now I hunger ONLY for revenge! AND I. SHALL. HAVE IT!"
The G-Man in Half-Life 2: Episode One. He's been completely in control for everything so far, but the Vortiguants preventing him from taking Gordon causes him to become very angry. Even so, the only emotion he displays is slightly annoyed, "We'll see about that."
Knights of the Old Republic 2 has the Handmaiden, who is calm almost to the point of being icy until you approach her about the possibility of training her as a Jedi.
Morrigan of Dragon Age: Origins is one of the calmest and most collected individuals you will ever meet, except for a few scenes during her romance arc.
Sten: calm, stoic, sarcastic...then complete his personal mission, and you get to see him crack a smile.
Agent 47 in Hitman: Blood Money. Diana's apparent betrayal causes him to become visibly angry, and even prompts his first, and so far only, outburst of verbal aggression.
Agent 47: "Bitch!"
Also in the supplemental material, the young 47, normally just as cold as his adult self, starts crying when a runaway lab rabbit, he adopted as a pet, died and was buried, much to Dr. Ort-Meyer's surprise.
Gears of War 2 has several moments where Marcus Fenix shows some form of emotion other than seething, barely-contained fury. In particular, when Dom has to euthanize Maria, he looks like he's going to break down into tears - for just a moment.
Also exhibited when Ben Carmine dies, as it seemed that he was developing a certain amount of respect and attachment to the rookie.
In the third game, he becomes quite frantic when Dom sacrifices himself to save the rest of the squad, before going into a Heroic Safe Mode that lasts until the Stranded leader Griffin refuses to let up on trash-talking the COG, resulting in Marcus totally flipping his shit:
Marcus: "I JUST LOST MY FUCKING BROTHER! YOU HEAR THAT?! MY BROTHER!!! YOU, YOUR TOWER, AND ALL THIS FUCKING IMULSION CAN GO TO HELL!!!"
Super Robot Wars: Kyosuke Nanbu is generally the mascot for Mr. Grumpy amongst his peers. Even when he's completely mad when his girlfriend Excellen is being threatened to death, all that comes out was a Tranquil Fury. But this man literally broke down to tears when he thought that it was his fault that his other friend (read: OTHER FRIEND, not girlfriend) Lamia is dead (turns out she didn't, quite). Likewise, although he doesn't jump up and down in joy when his rivalturn good Axel eventually saved her, he was expressive enough to let out a genuine, grateful smile.
Also from Super Robot Wars is Raidese F. Branstein, he usually plays the cool lancer to hot head Ryusei but when he comes across Archibald Grims, the man responsible for the terrorist incident where his adored sister in law was killed, he goes completelyberserk and gets shot down (and almost killed) for his trouble.
Roxas from Kingdom Hearts II is shown to have been pretty darn stoic, even for an Organization XIII member. And then you later see him going batshit insane on machinery because he's incredibly pissed off at being manipulated, and even see him crying and yelling at DiZ that he hates him.
Also, Saïx is very stoic and unemotional for the most part. But then, like a freaking werewolf, he goes apeshit when the moon shines down ("BE GONE!" "MOVE ASIDE!" "ALL SHALL BE LOST TO YOU!")
More traditionally with Saïx, as he fades away after being defeated, his last words have him reaching out towards Kingdom Hearts muttering "Kingdom Hearts...where is...MY heart?"
While most of the nobodies are stoic, even when they break down Di Z insists that it's a ploy, and that nobodies can't feel any kind of emotion.Kingdom Hearts Dream Drop Distance Reveals that Nobodies eventually regrow new hearts, which means that when the Organization shows anger, panic, disbelief, or a fear of death, it's genuine.
Kingdom Hearts II also posses a unique positive example of this trope regarding Tron, a program. After the defeat of the Master Control Program, Tron is suddenly all playful and full of emotion. KH3D confirms that programs are not so different from Nobodies, in that they don't possess hearts either, but since the same game confirms that Nobodies can grow hearts over time, it's quite possible that programs can grow hearts too, so it's possible that Tron grew a heart of his own, explaining his sudden emotions.
Persona 4 has Naoto Shirogane, a young genius hired by police to assist in finding Inaba's serial killer. He maintains a cool, confident air most of the time, but once confronted with his Shadow, it starts to become extremely difficult for him to remain calm...
Jin Kisaragi from BlazBlue is mostly a stoicasshole. However... if he ever comes across with Noel Vermillion, his stoicness kinda fades and he becomes a screaming lunatic hell bent to kill Noel. And if he meets Ragna The Bloodedge, the stoicness transforms into something... uh... more questionable.
Likewise with Nu-13, a Robot Girl who speaks in a mechanical monotone...except when she's squaring off against Ragna. Then she goes full Yandere.
ADA in Zone of the Enders is an emotionless computer, and at one point Leo even calls out her attempts to show emotion as being proof that she doesn't feel anything at all. However, she has a very tender moment with Leo after Celvice gets shot, and, right at the end, her voice cracks as if she is crying while she tells Leo, "This is what we live for - those of us who have no life".
JC Denton from Deus Ex isn't completely emotionless, but certainly very stoic. There are a few times his voice breaks, however, such as when he meets his brother Paul after the latter had defected from UNATCO and who was dying. Unfortunately, his most emotional outburst is a very narmy cry of "A BOMB!" when Jock discovers a bomb on his helicopter.
Vergil from Devil May Cry is pretty cold for most of the third game...except when his attempt to fully open Temen-Ni-Gru doesn't work (Arkham deliberately left out a few steps). Then he gets pissy: "Why isn't this working?!?"
In the first game, Wrex is cynical and almost devoid of emotion the entire playthrough, until he nearly suffers his Heroic BSOD when he learns that the villain, Saren, is making a cure for a sterility plague infecting his people and it has to be destroyed.
And in Mass Effect 2, should Wrex survive Virmire he greets Commander Shepard with a hearty greeting, some suspicious-sounding throat-clearing noises, and a heartfelt "Shepard! My friend!" before going back to his normal Deadpan Snarker self.
In Mass Effect 3, if Shepard sabotages the genophage cure by killing Mordin or Padok, Wrex's response is to storm onto the Citadel and try to blow Shepard's head off with a shotgun. If Shepard tries to talk him down, telling Wrex that no one was killed by the genophage sabotage, Wrex's response is an absolutely furious "No one, EXCEPT FOR MY UNBORN SON!"
The Geth teammate Legion also has shades of this. Occasionally, his "I'm an emotionless robot" facade cracks, such as when confronted with betrayal or unpleasant revelations, when asked pointed questions about his illogical behavior, or when playing Galaxy of Fantasy.
Paragon Shepard in the OverlordDLC. Shepard is absolutely furious upon learning of the experimentation going on inside. You know it's serious when a character that Would Not Shoot a Civilian outright clubs someone... as a paragon interrupt.
When you have a drink with Liara at the end of the Lair of the Shadow BrokerDLC, she asks you how you're really doing. One of the options is to admit that you're just as worried and afraid as everyone else.
In the ending of the Tuchanka arc, when Mordin is confronted about trying to cure the Genophage despite having formerly upgraded it, he will loudly exclaim "I made a MISTAKE!". This is doubly poignant because Mordin previously used passive voice and clinical language to downplay his own guilt in the genophage upgrade, so it's a big surprise to hear him take personal responsibility for it. Normally, he would say something like "Mistakes were made", but he doesn't — it was his mistake, he did it, and he knows it.
Legion has a much more dramatic Not So Stoic moment in 3 compared to his emotional reactions in 2 if you refuse to risk the lives of the attacking Quarians by letting him upload the Reaper Code to save the Geth. The first refusal has Legion attempt to appeal to Shepard's reason with real desperation in its voice, saying "This is not justice!". If Shepard refuses, however, Legion nearly kills them in a fury equal to Wrex's.
Legion:NO. We will not let you decide our fate. UPLOADING THE CODE!
Cyrus, no matter how emotionless he claims to be, gets pretty pissed off in the Distortion World in Pokémon Platinum. And earlier, when he first told you that he'd rid himself of emotions, he does so during a fairly intense rant, complete with many exclaimation points.
In Pokémon Black and White, gym leader Elesa acts like a Emotionless Girl, but is overwhelmed by excitement when you beat her, immediately becoming embarrassed over it. In the sequels, Black 2 and White 2, her Memory Link scene with Skyla reveals that she felt she had to act stoic as a model and gym leader, and that she wants people to see her as more sociable by telling puns... which, according to Skyla, still need some work.
And earlier in the same game, we saw him get angry for the first time ever.
Richard of Tales of Graces is usually quite a calm, stoic man, even when he was younger. In the main part of the story though, he has the tendency to go batshit insane over rather minor things. While his sudden violent outbursts could be viewed as rather Narm at times, Asbel is usually left gaping in disbelief at him. It's a result of him being possessed by an Omnicidal Maniac.
And then the future arc in Graces f shatters that stoic personality altogether. Keep in mind this is after Lambda releases him and moves on to Asbel. He's more prone to rampant trolling and explosive moments of ham than stoicness. Mask of Barona, anyone?
In Metal Gear Solid 4, Raiden appears to become very much The Stoic... until his tearjerking breakdown in the latter part of the game, when Raiden declares he has NOTHING left to live for except for following Snake and his vision for freedom for themselves. Snake, knowing he'll die soon tries to discourage Raiden from following him, but the badly injured Raiden drags himself along the floor and desperately clutches Snake's leg, begging him not to leave him alone after having lost his parents, his innocence due to his child soldier days, his love and his child.
In Final Fantasy VIII, Squall Leonhart starts out as The Stoic, but his stoicism breaks down spectactularly as his coping mechanisms prove increasingly inadequate, starting with the short meltdown he has over the way people talk about Seifer after his supposed death.
When Rinoa ends up in a coma, he breaks down completely.
Agent Superball in the Sam & Max Telltale Games is an unflappable Secret Service agent who spends the whole series speaking in a flat monotone (except for one impromptu musical number). However, at the end of the series, the death of Max is too much for him.
Superball: (still deadpan) I'd just like to offer my- I can't do this now. I just can't. *runs off sobbing*
The Arishok in Dragon Age II. In most of his appearances he is The Stoic, but it's pretty obvious that being stuck in Kirkwall is getting on his nerves. In the aftermath of "Blackpowder Courtesy" when confronted by Hawke about why he doesn't just leave the city, he reveals, with barely contained fury, that it's because someone stole a Qunari relic and was last seen in Kirkwall. He calms down after this rant, but as Varric notes, he's like an ox waiting to charge. And at the end of Act II, he does.
Arishok: Let them rot. Filth stole from us. Not now, not the saar qamek. Years ago. A simple act of greed has bound me. We are all denied Par Vollen until I alone recover what was lost under my command! That is why this elf and her shadows are unimportant. That is why I don't simply walk away from this pustule of a city! Fixing your mess is not the demand of the Qun! AND YOU SHOULD ALL BE GRATEFUL!
Aveline gets adorably flustered when faced with anything related to Donnic; Fenris flips out if he's grabbed by the shoulder or called a slave (or if a romanced Hawke falls in battle). And while Varric, the Team Mom, isn't so much stoic as easy-going, finding the results of his brother's insanity is the one thing that gets him seriously pissed off.
In Disgaea 4, Fenrich usually serves as the calculating, Tall, Dark and SnarkyChessmaster who's usually one step ahead of his enemies and even his own allies. However, slighting his master Valvatorez proves to be an effective Berserk Button, and when Judge Nemo reveals that he's taken steps to blow up the moon, both a source of power for werewolves and a symbol for the oath Fenrich swore to Valvatorez, Fenrich loses any semblance of composure and spends the entire chapter in a frothing rage.
Final Fantasy X: Auron, after Kinoc's death, gets very pissed about it, and Lulu's deadpan demeanour cracks badly upon learning the teachings of Yevon were lies.
Auron also loses it when he sees a memory preserved by the pyre-flies of the moment he failed to prevent Braska and Jecht from going through with the Final Summoning. He furiously attacks the image of his past self, enraged at his helplessness.
The first two Max Payne games had Max running mostly on Tranquil Fury and stoicism. However, Max Payne 3 features a Max that, after discovering a horrifying organ harvesting ring, completely loses his shit and fully indulges in Unstoppable Rage.
The Master Chief is unflappable. Though thoughout the games certain things weigh on him (such as Keyes and Johnson's deaths), he generally remains stoic and gets the job done. Come Halo4, and he stays in denial over the severity of Cortana's rampancy, assuming that it can be fixed, and when she sacrifices herself to get himself off the Didact's ship as he blows it up, he's audibly upset and can't even look her in the eyes. He even sheds a tear afterwards, as seen on his visor.
Similarly, Truth. In Halo2 he never showed any form of emotion, even with the facts of Halo 04's destruction and the discovery of Halo 05 but...in Halo3 it's revealed that his stoic personality was just a facade to hide his psychopathic, sadistic personality and extremely high temper.
The Batter in Off is shown to be cold, determined, and unfaltering in his mission to purify the world...but he does rather enjoy roller coasters, as seen in a photo from Zone 2.
Ib: The titular protagonist is a Heroic MimeStoic despite only being nine years old in a horrifying surreal maze of living art. She manages to hold it together pretty well, but there are two occasions where it slips a little; first, when she sees a portrait of her parents, the implications and stress of what has already happened drive her to faint and have nightmares. The second time is if Garry fails the Doll Room event, and is driven insane. Depending on circumstances, it'll either be a heart-warming hug when Ib manages to snap him back to reality, or she'll rocket past the Despair Event Horizon fast enough that her will to live shatters like glass when she realises he's past saving.
Inverted and then played straight in Phoenix Wright: Ace Attorney - Dual Destinies . Bobby Fulbright, a goofy, over-the-top bumbling detective is revealed to be "the phantom", a sociopathic monster who experiences no genuine emotions (though with enough concentration he can fake them accurately enough to fool even the various gadgets and magic powers used specifically to see through people like him) and has literally no personality; a large part of the trial has him mocking "the masses controlled by emotions" and bragging about how his lack of humanity makes him unbreakable. It turns out he isn't completely without emotions, however, as the risk of having one's cover blown and getting assassinated on the spot is enough to even make the phantom feel afraid. And as that scenario becomes more and more likely . . .
Little Busters!: On your first playthrough, Kengo will come across as totally serious and immune to the wild antics of his friends, dedicating all his time towards playing Kendo and not even participating in the baseball game in the end. In all future games, though, halfway through the common route a scene will play where Kengo saves his friend from committing suicide and breaks his arm in the process...and from then on becomes downright giddy, smiling all the time and making himself look just as silly as everyone else. The others are clearly unnerved by the transformation.
And from a different direction, when Riki beats him in the baseball match in Refrain, he bursts into tears outright over how much time he wasted on Kendo for nothing. Later as they're disappearing, he's noticeably teary-eyed, and Kyousuke comments that in fact, he's the biggest crybaby of the five of them.
Sakazaki Yuuya of Hatoful Boyfriend wouldn't immediately appear to be a stoic. He's friendly and cheerful, or he's professional, or a little cruel, or he's a mix, depending. However he is a hugeStepford Smiler whose attitude doesn't change even in enormously stressful situations such as when he's dying and he always seems relaxed and careless, giving away nothing of what's happening inside. Now and then his mask cracks for a moment but he's always able to repair it... however, during a side story in Holiday Star he finds out that his brother's butler is actually an assassin and just loses it with fear and worry, even making bald-faced threats.
Celestia Ludenberg in Dangan Ronpa usually presents herself as a stoic, pragmatic, Elegant Gothic Lolita. However, she does have some Berserk Button and if pressed, her expression changes into a deranged, screaming lunatic. She's the culprit of the third case, and when about to be exposed, she pretty much puts on the deranged self all the time, until she's exposed and decided to be a Graceful Loser.
Hisao from Katawa Shoujo instantly knows that something is terribly wrong about Lilly when she accidentally trips due to another kid being careless (mind you, she's blind) and mutters "damn" under her breath while getting up. Think about it: Lilly has such nigh-inhuman levels of self-control and politeness that she can say what most people wouldn't even consider a real swearword these days, and people would get worried.
Chapter 6 of Gunnerkrigg Court, where, seemingly out of nowhere, Emotionless Girl Antimony starts bawling her eyes out over her mother's death. This marked a turning point for Antimony—since then, she's opened up to her close friends, while maintaining a stoic façade to the rest of the world.
She also loses her cool near the end of chapter 19, when "Kat" is disintegrated by Gamma.
A weakness isn't normal, child. That Place poisons you.
Dave Strider from Homestuck. He does not take his friends and family dying well.
Karkat Vantas, sharing many similarities to Dave, may also qualify. He's far from emotionless, but he certainly wants his friends to think of him as a stalwart leader. But watching his friends die is something he's not very stoic about, and as a result he's been shown weeping more times than probably any other character. In fact, he's probably the most emotionally susceptible of any of the trolls.
Rose Lalonde's demeanor was cracked with the death of her mother where she immediately blamed herself. Her level of sanity after she goes Grimdark is questionable, but she was fairly stable until Jack killed John where she then attacked him in an eldritch rage. During the Meteor intermission she begins drinking she's less guarded but also falls into an inept stoop. When she snaps out of it, she expresses regret at having fallen into that rut.
Doc Scratch is always polite and composed, be it when serving guests, beating them up, narrating, or abusing a child. When he finds out that Vriska has his cue ball, he has an outburst so powerful that it screws with reality. Another example would be when he's talking to Gamzee, where he drops his attitude and declares all of them to be suckers as he's won.
Dirk could effectively be described as having all the stoicness we've seen from the Striders, while having the angst and self loathing of Karkat mashed into one. He doesn't really seem to try and hide his emotions though and is surprisingly straight forward with them.
Legend Of Korra: In Season 2 Eska's reaction to Bolin's break-up shows her true possessive and horrifying nature.
Played for Laughs (most of the time) with Tenzin; he tries his best to appear as the stoic, wise Airbending Master. When Korra's acting too much like a Bratty Teenage Daughter, or his older siblings start picking on him, or when he's run ragged by his young children, that composure fractures.
Raven of Teen Titans strives for utter calm and control over her emotions—making it that much more frightening when she lets her temper show. The episode "Nevermore" begins with Raven torturing a villain, and the fourth season's Trigon arc features her angrily attacking and yelling at both Slade and Trigon.
Justified, though, because it was mentioned once in a "Freaky Friday" Flip episode that her powers are controlled by her emotions. Cue Starfire exploding things without noticing when she had Raven's body, or Raven accidentally kidnapping all other Titans and creating an army of monsters when she was scared by a horror movie.
In The Grim Adventures of Billy & Mandy, Mandy is normally emotionless, but in the episode featuring Pandora's Box, upon realizing that she had unleashed it, she is overwhelmed with fear/shock. Also, the episode when her nerve is stolen from her.
And the episode "Heartburn," when she finds out she may actually like Irwin. Also: "Billy And Mandy's Big Boogey Adventure." The Boogey man has Mandy (asleep) observing her greatest fears, and later she brushes tears from her eyes when she thinks the Kraken has eaten Billy.
Very few things can make Prowl of Transformers Animated lose his composure. Unfortunately for Prowl, one of those things is his annoying teammate Bumblebee, who can provoke uncharacteristic displays of frustration in Prowl without even trying.
In the Batman Beyond film Return of the Joker, what the Clown Prince does to Tim Drake and the resulting retaliation taint the entire Bat Family's demeanors forever.
Adventures of the Galaxy Rangers: Zachary is a very quiet, steady, and stoic fellow, especially in contrast with the more colorful crew he's commanding. It makes it all the more powerful when it slips.
A comedic example during the Family Guy DVD special, "Stewie Griffin: The Untold Story." Tricia Takanawa, Token Minority news reporter for Channel 5 goes to interview David Bowie on the red carpet. It takes one sentence from Bowie to turn Tricia from deadpan reporter, to shrieking, leg humping fangirl.
Tricia: Oh, make love to me Ziggy Stardust! I take you home, I make you fishball soup! Fishball!
Tom: (Beat) Thank you, Tricia, for successfully setting your people back 1000 years.
As mentioned in the quote, this applies to Wind-Whistler from My Little Pony. The line in question comes from Crunch the Rock Dog.
Towards the end of Lesson Zero in My Little Pony: Friendship Is Magic, after all the brainwashed characters are cured and give up fighting over the Smarty Pants doll, we see the normally stoic Big Macintosh grin childishly and run off with it complete with little love-hearts around his head.
He gets another one in "The Last Roundup": we see quietgiant Big Macintosh's lip quivering when he gets the note that Applejack's not coming home.
Done for a humorous role reversal in the episode "Ponyville Confidential". The town is mad at the Cutie Mark Crusaders for their gossip rag. They try seeking forgiveness from Applejack and Big Mac, but Applejack only responds in Macintosh's usual "yep" and "nope"s, while Macintosh chews them out for what they did. He probably says more in that scene than he does in the rest of the series combined.
In the episode Maud Pie, Pinkie's eponymous sister spends most of the episode as a drab, monotone Emotionless Girl, until Pinkie is in danger of being crushed by a boulder. This causes Maud to run faster than any of the other ponies with a determined expression, punch the boulder to dust with her bare hooves, and after bringing Pinkie down from the rock slide, hug her out of relief and raise her voice when scolding her. She also smiles at the end of the episode, saying she loves Pinkie Pie.
Phineas and Ferb: Ferb is one of the most stoic cartoon guys you ever hope to meet. The look on his face is 99% of the time, entirely blank, and he speaks, on average, once an episode. He does, occasionally, get moments of emotion, but his first true Not So Stoic moment happened in his firstmovie: When he and his brother meet their other-dimension counterparts, the alternate Phineas sees Perry and immediately hugs him, thinking he's their Perry, finally come home. When Phineas tells him that it's the wrong Perry, he then asks "Wait...can I hold him a little longer?". Cut to Ferb, along with his other dimension counterpart, shedding a single, small tear.
It is rare to see Optimus Prime from Transformers Prime to show any sort of emotion. He only really loses it twice: once when Raph is injured by Megatron, and once when Starscream steals the Omega Keys.
Cellbound has the ever-serious jail warden, who nevertheless begins doing an incredibly goofy dance upon hearing some music (then goes back to serious and stoic within a single animation frame).
Norwegian Terrorist and Mass Murderer Anders Behring Breivik bragged about how he had trained himself to disregard any and all emotion and described himself as a Knight Templar. This however, did not stop him from writing a 27-page long list of complaints on his prison cell surroundings, like how the pen he was given caused his hands to hurt and how he could not bring his own Vaacum Flask.
Newscasters are supposed to be stoic, and Dan Rather has been exceptional in this regard, reporting on everything from the assassination of John F. Kennedy (as CBS's Dallas correspondent) up to the events of 9/11—at least in his own newscast. However, he was very humanly emotional when he was David Letterman's first guest when Letterman's show returned after 9/11.
Bosses and other authority figures are also supposed to be stoic and not let others — particularly their subordinates — into their private lives, particularly the more traditional ones. But every once in awhile, even the most traditional of superiors will let their iron-clad facade fall.
The Trope Codifier for Oh, the Humanity! is an earlier case of this. After calmly narrating the Hindenburg's approach to the mooring tower, newsreel announcer Herbert Morrison was horrified and at a loss for words when it caught fire.
Walter Cronkite briefly lost his composure on the air when he reported the official statement that John F Kennedy had died. ( Video here, the composure slip starts at just about 5:00)
His facade also briefly parted during liftoff and ascent of John Glenn's Mercury space-capsule flight.
Hideo Kojima's reaction to the question of whether Uwe Boll would be making a Metal Gear movie was supposedly... spirited, to say the least.
Tennis player Andy Murray has a reputation as being quite stoic and serious...until he lost in the finals of Wimbledon 2012, and had to fight tears most of the way throughout his final speech.
Roger Federer has an even more established reputation as a cool and unflappable maestro who never lets a strand of his hair get out of place on court, but he occasionally does things like breaking down in tears after losing the 2009 Australian Open final and yelling at the French Open crowd to "Shut up!" while on the brink of getting eliminated by del Potro that remind you that he's just as human as the next player.
ABC News anchor Peter Jennings was known to be as charismatic as possible without losing his journalistic cool. He'd been in the business since the mid-1960s so he knew to be a consummate pro. But when he told his viewing audience about his cancer diagnosis (of a cancer that would eventually take his life) and need to retire, you could hear his voice cracking and his eyes full of sadness.
The head of the stoic school, Chrysippus, was an example: He died in a fit of uncontrollable laughter.
MMA fighter Ronda Rousey is always extremely cold and composed in the lead up to her matches, complete with death glares. Once she has won she instantly becomes much more relaxed and shows more personality. How she would react if she lost is unclear as of yet…
