In Fist of the North Star, being a good guy SUCKS. The world is such a cruel, dark place that the only ones who truly enjoy their lot are the rotten ones, while the heroes must fight their own despair as well as the bad guys. Part of the reasons so many Manly and Tender Tears are shed in the series.
Mazinger Z: Before the beginning of the show, Kouji had lost both their parents. The first episode the maid that his grandfather had hired got murdered in cold blood in their own home, and later his grandfather died in his arms. Throughout the whole series alot of people -several of them close to him- gets hurt and dies cause the war between Dr. Hell and him (Prof. Yumi gets hurt by an angry mob, making Sayaka nearly quit, Minerva dies, Prof. Morimori dies, Erika gets killed, he has to fight and kill a girl his brother had fallen in with...). Later in Great Mazinger he finds that his father has been alive all along only for losing him definitely shortly after. And in UFO Robo Grendizer, when finally it seems life will be peaceful from now on, he gets involved in a third war. The saddest part is when you realize his Annoying Younger Sibling, Shiro, has it worse than him.
Great Mazinger: Tetsuya lost his parents when he was a little child. On the surface he looks like a hot-tempered, arrogant Jerkass, but that is nothing but a cover to hide that he is plagued with neuroses and insecurities, and he is deadly frightened of being abandoned again.
UFO Robo Grendizer: Duke Fleed. Oh, my God, Where we begin? Before the beginning of the series, the Vegan The Empire Alliance killed his whole family or so he thought, murdered most of his planet's population and turned the whole planet into a radioactive wasteland, forcing him to run away. A while later he has found a new homeworld where starting a new life and his wounds are beginning to heal when the Vegan Empire strikes Earth and he gets forced to fight despite of he hates war. Throughout the series he sees dying many people, some of them by loving him and refusing harming him. Later he finds out that the Saucer Beasts that he has annihilated are powered with [[spoiler:brains of Fleedian inhabitants, some of them friends of his.] Have we mentioned that he's dying via a radiation-inflicted wound he suffered during his escape and knows his days are numbered? And at the end of the show his fiancee (and Big Bad's daughter) reappears to beg him forgivennes by her father's actions and talk him into get married with her -so they can end up with the war without further bloodshed and rebuilding his homeworld-, but after he accepts she gets killed?
He even admitted to Hinata that the smile is a mask, and Pain put him on the ropes by breaking him down with words, getting him to second guess his own actions.
While attempting to gain complete control of the Kyuubi, it was revealed that despite finally achieving his dream of being respected and loved in Konoha, Naruto still had deep-seated issues from his childhood holding him back both from defeating the Kyuubi and embracing his new-found fame.
Science Ninja Team Gatchaman: Ken "G1 The Eagle" Washio (or Mark) lost his father when he was a little child. Later he finds out that his father is alive only to see how he was Killed Off for Real shortly after. At the ending of the series, Joe commits a Heroic Sacrifice to save them. At the next series his mentor and surrogate father gets killed. All of that trauma slowly wore his sanity off, and although at the beginning he was the prototypical The Hero and The Leader with Nerves of Steel, for the final series he had become so violent, uncontrollable and impulsive like The Lancer.
Vash The Stampede of Trigun, especially later in the series. And let's not even get started on the manga, where he's a Stepford Smiler of epic proportion and has a few Heroic BSODs and fits of Unstoppable Rage (not to mention the scenes of epic alcoholism). Meryl is shocked when she gets engulfed in his memories during one of his most spectacular Heroic BSODs and realizes he's just a ball of pain.
This is somewhat the point of Mobile Suit Gundam. Amuro is a massive ball of Wangst, but he still manages to basically single-handedly win the One Year War for the Federation and proceeds to kick more evil asses in the next few followingmajorconflicts.
Setsuna is also of this trope. He pretends to be The Stoic but inside, he's a huge ball of pain and self-hate for coldly killing his parents because Ali says so and later when his best friend Lockon Stratos pulls a Heroic Sacrifice and dies because Setsuna arrives to a battle too late. And if that wouldn't be enough, The Movie undoes two seasons' worth of Character Development by revealing that after Setsuna turns into an Innovator, he can no longer find his place among ordinary humans and is thus purposely distancing himself from them - even going as far as playing the ignorant at Feldt's timid approaches.
It could be easier to say that an overwhelming majority of the 00 cast is this trope.
Edward Elric from Fullmetal Alchemist is constantly burdened with guilt over pressuring Alphonse to help him with his efforts to bring their mother back through human transmutation, and causing the subsequent loss of Al's entire body (and the loss of his own arm and leg). He also feels anger at his father's abandonment and holds him responsible for his mother's death.
For that matter, Alphonse is wracked with guilt about his brother losing his arm to save Al's life.
To say nothing of the fact that during both brothers' times seeing The Truth about alchemy, he got a bunch of wonderful images flash through his eyes (Yes, this is why they were screaming after it happened). And it happened to Edward twice, since he used the Human Transmutation circle again to escape Gluttony's stomach.
Roy Mustang, Riza Hawkeye, and Alex Louis Armstrong are all wandering around with buckets of guilt over the parts they played in the war in Ishval, where they were ordered to massacre innocent people. On top of this, Roy and Riza have sizeable doses of Love Hurts.
Bleach: Ichigo Kurosaki believed for a long time he was responsible for his mother's death. As a result, he takes it hard whenever he fails to protect others or save the day. This eventually came to a head when he was manipulated by a villain who stole all his powers and left him utterly unable to protect anyone, including himself. He was reduced to tears.
Kenzo Tenma from Monster. He saved the life of a murderer, and decided to take responsibility for it.
All three Magic Knights were this at the end of the first series of "Rayearth" and the beginning of the second. They hated how they killed the very person they sought to save, and having Zagato's blood on their hands as well made them even more depressed.
Mami and Sayaka too. Mami regrets not saving her family with her wish, and Sayaka learns the truths about being a Magical Girl and it really gets to her. In fact, due to the nature of the Magical Girl system in this anime, every single mahou shoujo goes through complete hell before either turning into a witch or dying.
Van of GUN×SWORD exemplifies the broody Anti-Hero version: he's one of the gloomiest heroes you'll ever see. It's implied that at one point, he dealt with his pain through drinking (hence the nickname "Hangover Van"); he also seems to use violence to cope with it.
Yuri Tsukikage/Cure Moonlight of HeartCatch Pretty Cure!. On becoming a Precure, she immediately develops the mindset of "I'll shoulder all the burdens so no one has to suffer", carrying all those loneliness with a smile, which instead backfired when it cost the life of her fairy Cologne, and then she was utterly trounced by Prof. Sabaku and Dark Precure, losing her Precure powers and most of her cheeriness as a result. When she regains her power and spirit, she ends up discovering that Sabaku is her Disappeared Dad, Dark Precure is her 'sister', said dad was killed by Dune protecting her. If not for Tsubomi reminding her what's at stake, she would have given in to hatred and despair. But in the end, she prevailed without giving in to all her misfortunes.
The mantle of hurt has been passed down to Kenzaki Makoto/Cure Sword of DokiDoki! Precure. This is also the installment that gives us not one but two different characters who are nicknamed Cure Batman, but neither of them fit this archetype.
Cure Heart, AKA, The Protagonist of the series, seems to be well on her way to becoming one of these.
If one put all the angst all of the mutants in X-Men have suffered, you'd probably have a worthy opponent for the angst caused by the Holocaust. Which has happenedmultiple times to mutants in the Marvel Universe. At least a dozen if one counts alternate timelines. Not to mention the mutants who were in the actual Holocaust.
The last couple of writers on Daredevil (Bendis and Brubaker) have seemingly competed to see just how much pain they can put Matt Murdock through. Just in the last two runs, he's gone though a mental breakdown over the death of his longtime girlfriend Karen Page, his secret identity was blown and he was sent to a high security prison (filled mostly with crims he'd put away) for obstruction of justice, his wife was driven insane by a supervillain and committed to a mental hospital and his best friend was stabbed and assumed to be killed.
Mark Steven Johnson adopts the same tradition for the movie. Matt Murdock's superhero lifestyle is depicted as being a thankless and torturous affair.
Since leaving the BPRD, Hellboy's life has become more and more like this.
Tony Stark, whose difficulty coping with the heinous crap in his life is actually a major character trait, what with the chronic depression and alcoholism and Survivor Guilt, etc. Rather exacerbated by his actions in the Civil War arc and its aftermath; in current canon, most other superheroes (and quite a lot of fandom) openly revile him.
Spider: A man in my delicate condition can't be expected to face the world without medication.
Empowered. Let's see, constant mockery and humiliation (much of which comes from her own teammates), a somewhat embarrassing track record that it seems she'll never live down down though she's getting better, an inability to hold a steady job... That's the small stuff. The big stuff includes a fellow superheroine and one of Emp's few friends sacrificing herself to save Emp (survivor's guilt, ahoy!) and watching her father die right in front of her on the kitchen floor when she was a little girl.
Doctor Strange, sometimes. He may enjoy the perks of being Sorcerer Supreme, but he is also responsible for every innocent life in the universe — expect a good wallow in guilt after a major disaster, even if it's something he never could have foreseen or prevented.
In Kitsune no Ken: Fist of the Fox, Naruto goes through some very deep self-hatred because of his past as a member of the Kyuushingai and the death and destruction the group caused for 365 days, two years earlier.
In Spaghetti Westerns, heroes hurt in more ways than one. Generally they are near-invincible gunslingers who are nonetheless subject to the most horrible of tortures. The titular character in Django embodies this, his invincibility almost becoming a curse to him because he is trapped in a cycle of violence he cannot get out of.
Optimus Prime in Transformers. See Western Animation for more detail.
The introduction of Steve Rogers in The Avengers shows him beating a punching bag until it bursts while remembering the war and his... vacation.
Iron Man 3 has Tony suffering from PTSD-like symptoms following his near-death experience in The Avengers and is obsessed with keeping his loved ones safe to the point where he has upgraded his armor 40 times since The Avengers.
Thor has to watch as his little brother goes insane and becomes a megalomaniac, and then he is personally tasked with bringing that little brother to justice. Then he is kept away from his sweetheart by the long, draining intergalactic war his brother's actions kick-started. Then he watches his mother die right in front of him, as he is seconds too late to save her. Then his father becomes suicidal due to the grief of his recent loss, forcing him to commit treason in order to preserve his homeworld's safety. And then his brother apparently bleeds to death in his arms. It's no small wonder that the poor guy needs a break by the end of the movie.
Just to illustrate, seers within the series state that the world is in a stagnating cycle, akin to a wheel driving a rut in the ground, endlessly. To kick things up, bring a little more life into the universe, the wheel's got to be kicked out of that rut. The easiest way to do that? Stick a pebble in its path, so that when the wheel crashes into it with enough force, it'll bounce out of the rut and into a new path. That's the metaphor. Now, guess who gets to be that pebble?
In Summer Knight, Martha Liberty votes for him because she realizes how much he is hurting — while he disclaims his (physical) wounds as minor. When Aurora offers him surcease, he realizes for the first time how badly he was hurting — and refuses, since it would mean giving up.
"After all you've been through, sometimes you deserve a little whine."
It's actually something Mercedes Lackey seeks to instill in a lot of her protagonists. She lampshades it once, saying her formula is to make the readers like the hero, then dump a mountain on them.
In Nick Kyme's Warhammer 40,000 Salamanders novel Salamander, Tsu'gan is deeply grieved by the captain's death and his own failure. Iagon actually uses it to foment his ambition: fighting at the head of the company would assuage his hurt. And let's just say it all ends up in more hurting for Tsu'gan.
Fugis confesses to having lost faith at the same time; Dak'ir thinks how Tsu'gan resorts to fury and Fugis to despair.
Dear god, Rand Al'Thor, the Dragon Reborn is the Patron Saint of this trope. To start out, he has access to the tainted male half of magic, everyone else with access to male magic in the last 3000 years went mad, rotted alive, and killed everyone in his vicinity. He's fated to destroy the world in saving it. He's responsible for taking the fight to Satan Himself, whose elite followers consider the current crop of Aes Sedai (wizards and witches) to be children at best. Then he discovers that his predecessor was literally reborn as a backseat driver in his mind. That predecessor is himself only somewhat sane, can't be revealed because it would be assumed that the current Dragon is going insane, has suicidal tendencies, tries to grab the magic out of the current Dragon's hands with regularity, and was well known for killing his entire family as he went insane, realizing for a single moment what he'd done, and committing suicide so dramatically that it made a volcano. The current Dragon is barely more than a teenager from a tiny farm village in the middle of nowhere. He seems fated to be a martyr for humanity. Everyone and their mother works against him - and most aren't even evil, merely selfish, superstitious, foolish, set in their ways, and determined to control this kid who is clearly not in charge of saving the world. His ancestral people have pledged to him - and some of their warrioresses act as his bodyguards, and he's lived his entire life expecting to protect women with his strength. That in particular scars him so much that he keeps a list of all of the women who have died where you could even hypothetically lay the blame at his feet. He was captured by Aes Sedai and tortured ruthlessly. Alanna once connected her mind to his, and spent the next month crying in the pain of it. Nynaeve, the limit-breaking healer, once looked at his mind and realized that there was nothing she could have done for him if not for Lews Therin's heroic sacrifice. To top it all off, nobody believes him, everyone thinks they know better than him, and as he's trying to save the world, the world is trying its hardest not be saved. He once quipped that the pressure of that alone should be enough to drive him insane, never mind Saidin.
Leia in Splinter Of The Minds Eye is clearly traumatized and mostly covering it by being sour and irritable. It's for good reason; like her brother, she can not show her pain after it's inflicted, but she went through a lot in A New Hope.
Luke, in Luke Skywalker and the Shadows of Mindor. Even before the villain puts him through Mind Rape, he shows signs of depression and strain, and after all he is the one active Jedi in the entire galaxy and trying to negotiate what that means, what he should do. But he keeps going. After that, he seems to be suffering PTSD, with constant flashbacks, heavy depressive nihilism, loss of faith... but he still keeps going, and his compassion and empathy never run dry.
Chloe Sullivan on a slightly lesser level than Clark. In season eight when her life is painfully falling apart, partially due to her own mishandling of the situation. She also fits the Stepford Smiler and Bad Dreams parts (she had a nightmare in which she saw Clark bloodily ripped into two, one of the most graphic scenes in the series).
Um, Buffy, anyone? Her life sucks beyond all reasonable measure, she goes through multiple Heroic BSOD, outright depression at points, yet she always manages to keep fighting.
Angel as well. He constantly fights against his vampiric side, can never be perfectly happy for fear of losing his soul, and must deal with over a century of the most vile sins conceivable he committed while soulless.
Jack Harkness from Torchwood. Just... In Children of Earth alone, first we learn he has a daughter and a grandson; while the grandson thinks Jack is his uncle, the daughter just really doesn't want anything to do with Jack. Then he gets blown up and feels it, comes back to life screaming with all of his skin still burned off, gets drowned and trapped in concrete, is thrown off a cliff while in the concrete, has his daughter and grandson taken hostage, and learns that he is partially responsible for the latest alien threat because he once surrendered 12 children to them. Then, just when it looks like he might be able to stand up to the alien threat, Ianto (his lover) is killed because of his very bad plan and dies in his arms, something Jack blames himself for. Then, to finally save the world from the alien threat, he has to kill his grandson in front of his screaming daughter.
In the previous season, the main villain is Jack's brother, who was captured because of Jack and forced to watch torture until he went insane. He ends up killing Tosh and Owen and burying Jack alive for almost 2000 years.
In Doctor Who, most of the Doctor's incarnations have something to be sad about, but in particular from Nine onwards, after the Last Great Time War in which he basically got the entire race of Daleks and Time Lords killed.
Doctor number Ten, especially. "Born from war" is an apt description, and the guy sometimes comes across as just one big moving mass of pain. Hell, he can make grown men and women burst into tears just by talking about his home planet.
The Doctor always suffers after losing his companions. Some leave, others get left behind, and some die. He always takes it hard, especially the latter, blaming himself for it and preferring to travel alone for awhile. After Amy and Rory are sent back in time by a Weeping Angel and die of old age and River refuses to travel with him permanently, he retires and swears off traveling through time and space, settling in Victorian London and refusing to even notice strange things. Then comes Clara Oswin Oswald, only to die before the end of the episode.
Quite a few of the crew of the not-so-good ship Serenity have been put through one form of hell or another in their lives. Malcolm Reynolds suffers under the weight of the chains of command and still bears quite a bit of pain from the end of the Unification War, and both Simon and River Tam have gone through horrifically traumatic experiences; Simon giving up everything he had to save his sister, and River having suffered three years of mind-shatteringexperimentation that left her insane and with uncontrolled Psychic Powers.
Olivia from Fringe has had her life described by another character as "something of a nightmare." And that's before she gets trapped in a parallel universe, tortured by light deprivation, brainwashed into thinking she's another Olivia, narrowly escapes having her brain cut out, and finally manages to get herself back home... only to find out that the other Olivia has been living her life and even dating Peter, the man she loves. Her life sucks.
Poor Merlin. Not only is he stuck looking after Prince Arthur (and never receiving any kind of recognition for his service), but he also has to actively hide the fact that he's magic, even when it costs him his friends, his love, and even his long-lost father.
Arthur also qualifies. He's under extreme pressure from his father to live up to his duty as the next king of Camelot, he's in love with a girl who is just a servant (and who still carries a torch for one of his knights) and now his newly discovered half-sister is trying to kill him.
Team leader Nathan Ford's son died because of his greedy boss. This led to divorce, alcoholism, job loss—and, eventually, his bringing together a group of Con Artists to help the helpless. However, Nate is still haunted by his demons, even after bringing his boss to justice.
Before he joined the team, Eliot Spencer was a mercenary/assassin who did things so terrible that he can't bring himself to discuss them, even with his closest friends. He doesn't see himself as The Atoner, because he believes his sins are unforgivable.
Parker's foster parents (at least her father) were so abusive that she blew up their house, possibly while they were still inside. She then spent the rest of her childhood and young adulthood learning how to be the world's greatest thief. All this might explain why she's a Cloudcuckoolander with an Ambiguous Disorder (possibly Asperger Syndrome) who has trouble relating to people, although her teammates are helping her with that.
In 24, Jack Bauer is a tragic hero who has everything in his life taken away from him. He tries to sacrifice himself for the United States with a nuclear bomb in season 2. His life goes even more downhill from there.
Mac Taylor in CSI NY ,who spent a lot of his series struggling with the loss of his wife on 9/11 and basically retreated into his work to forget the pain.
Both Sam and Dean in Supernatural are made to repeatedly suffer, with the repeated themes of losing their loved one, failing others, and being tortured by demons.
Raiden becomes this so hard in Mortal Kombat 9. His actions slowly keep making things worse for Earthrealm, the heroes die one by one under his watch, and the Elder Gods seem to be pulling a major The Gods Must Be Lazy trip. By the end of the game, his actions narrowly prevented Armageddon from happening, but at the cost of practically all of Earthrealm's champions. Even Liu Kang, Raiden's favored champion, is dead (although unintentionally) by his own hand, after having first turned on him for the tragedies he so far caused. He carries the guilt of his actions throughout the entire game and you can tell it takes its toll. By the game's ending, he's emotionally and physically exhausted. And The Stinger at the end just makes it even worse. Seriously, the guy probably needs a hug badly when all's said and done. And his job is not going to be any easier for the next quarter-century.
Hawke of Dragon Age II after his/her mother's death. You get a few minutes of Hawke just sitting in his/her house in a deep, crushing depression.
Both original Mega Man original and X, often wonder how long they're going to have to keep fighting.
Garrus Vakarian as of Mass Effect 2. His career as turian Punisher really hasn't gone well for him, and to top it off, his family thinks he's a slacker and has no idea of his saving the galaxy. Especially evident if you pursue his romance, in which he eventually tells Shepard (the one person in the galaxy that he trusts and respects the most) that the reason he's been so awkward and nervous about their relationship is that he so badly wants it to be the one thing in his life that finally goes right.
Ashley and Kaidan, if they survive Virmire, is one of these in Mass Effect 2, despite their small role, and in the beginning of 3. Literally, too, after Dr. Eva beats the crap out of them on Mars and they nearly die. A hefty dash of Broken Pedestal for Shepard combined with Udina's betrayal will do that. Fortunately, they can overcome it.
It's very heavily implied throughout Mass Effect 3 that Shepard has become a Death Seeker. While s/he's still willing to fight the Reapers, it's implied that s/he would consider death a great relief.
A spotlight comic reveals that, during his last stand on Omega, Garrus calls his father to admit he (Garrus) was wrong and as a final goodbye, knowing he will eventually be overwhelmed. His father brushes off the goodbyes and wants a tactical update on the situation (a flashback scene also reveals that Garrus learned to be a crack shot from his dad). Then Garrus sees the N7 armor in his scope and tells his dad that his odds just improved before hanging up. Given that Garrus officially joins the Turian military by ME3 and even attains a high rank, it can be assumed his father is now proud.
Midna in The Legend of Zelda: Twilight Princess turns out to be this, initially for abandoning her people after Zant turned her into an imp and later for being so selfish with Link and Zelda despite all the sacrifices they made to help her.
Link himself, more than once. In The Legend of Zelda: A Link to the Past, he's already an orphan, immediately proceeds to lose his uncle/godfather, and is framed for the kidnapping of Zelda (arguably his only friend at that point) soon after. In The Legend of Zelda: Ocarina of Time he's already the "Boy Without A Fairy," so getting one means he's on his way, right? Yeah, on his way out of the only world he's ever known, blamed for the death of yet another father figure, while leaving behind his only remaining friend. Then he makes friends with Zelda, who needs his help to stop the evil Ganondorf. Sounds good — at first. One could argue Majora's Mask (searching for "a lost friend" — presumably Navi — that he never finds) as well. Oh Link, you happy-go-lucky elf, you.
The Hero of Time is a canon case, since the new anniversary book confirms he's the Hero's Shade in Twilight Princess. Regardless of what else he did with his life, he was never able to let go of his perceived duty as hero.
He did apparently learn to talk though, so there is that...
Solid Snake is one of the best examples in gaming. It would take such a long time to explain all the crap this guy has gone through, you just need to play the games.
As a summary of Solid Snake (let alone Big Boss/Naked Snake or Raiden)
Metal Gear: He is forced to fight and kill his father figure who betrayed him.
Metal Gear 2: He is forced to fight and kill his best friend (Grey Fox) as well as his father figure who has survived. And, after the flavor added by the Solid series, both fights are very much a case of both warriors acknowledging the necessity of the battle, but without any animosity. It also doesn't help that he finds out said father figure was actually his father...
Metal Gear Solid: Snake is once again forced to fight and kill people who, for all intents and purposes, are pretty nice people and enemies he respects. He is also forced to fight with the knowledge that, if he succeeds, he will kill the brother he only learned about the previous morning. Oh, and one of the only men he trusts has betrayed him (and the cute doctor has poisoned him). And he once again has to fight against his best friend who has suffered immeasurably due to their previous battle. And, depending on the ending, he may have contributed to the death of his friend's daughter.
Metal Gear Solid 2: Snake basically has to deal with the aftermath of helping the big bad of the series, has his name dragged through the mud, and has to continue to help the big bad in the hopes of finding a way to stop them.
Metal Gear Solid 4: Snake finally learns the true story of his birth (and finishes off becoming an orphan) and has to live with the knowledge that he is becoming a biological WMD and that, even if he finds a cure, he will die of old age before the year is out. And he is CONSTANTLY reminded of how his body has failed him.
Samus Aran. Metroid: Other M goes a long way towards showing just how utterly psychologically broken she is by the utter living hell that is her Doom Magnet life and quest for vengeance/justice. Post traumatic stress disorder in spades, dependency issues developing towards authority figures like Adam, survivor's guilt...
Samus worked mainly alone in her missions and whatever job the Federation tasks her to do, she always does it by her own rules. She most likely repressed everything that happened in her life and working alone allows her to focus on her objectives. It isn't until she sees Adam again in Other M that her suppressed feelings start to resurface.
Mickey freaking Mouse in Kingdom Hearts. He hides it like a pro, but his failure to save the Birth by Sleep crew continues to haunt him, over a decade later.
B.J. Blazkowicz in Wolfenstein: The New Order. Spending 14 years in a semi-comatose state only to awaken in a world conquered by Nazis, it's perfectly understandable he won't be smiling anytime soon.
Litchi Faye-Ling from BlazBlue is very determined to do the right thing that is curing her friend Lotte Carmine who turned to Arakune, caused by her Guilt Complex. However, in process, she ended up getting corrupted the same way as Arakune, had to keep this information to herself only, and against her preference, had to join a suspicious Troll and the worst father in the world, and left behind those other people she truly cared about as she has no other choice unless she wants the corruption catch up and ruin her forever. These facts have been hurting her so much, but even so, and despite everyone else calling her actions to be useless and lost cause, she is still determined to save him and do the right thing... while keeping a motherly smile on her face.
Sam Fisher starting with Double Agent, when he is told that his daughter has been killed by a drunk driver, the only person in his life who means anything to him. He ends up willingly going to jail as part of the mission to infiltrate a terrorist organization and has to perform questionable tasks for them. At the end of the game, he is put before a Sadistic Choice whether to shoot his boss/friend/mentor or the Big Bad (the latter would break his cover). The sequel reveals that he chose to maintain his cover and is on the run from the whole US government, although he does learn that his daughter is still alive.
StarCraft: In Koprulu Sector, you're either one of these or one of the monsters. Both Jim Raynor and Zeratul tried to do the right thing, and the universe repay them with lots and lots of hurts. Tassadar had the fortune to die in a blaze of glory rather than seeing his world fall apart around him.
Lexx from Alien Dice. He starts outbroken and hurting anyway, but it continues to get worse as the series goes along. He tends to hide it, but private moments and internal conversations show how much he's afraid of what will happen to him next.
Believe it or not, Axe Cop. As Malachi Nicolle, the child who writes the comic, is growing up and maturing, it's becoming clearer that Axe Cop isn't really able to enjoy himself.
I'm a perfectly ordinary girl and I have an ordinary life... but I've also got another life. And I hate it. I hate every minute of it.
All four main characters in Broken Saints are like this — especially the men. Shandala has a Dark and Troubled Past, but she doesn't let it haunt her everyday life until the plot gets going and bad shit goes down.
Most of Team Kimba from the Whateley Universe. Tennyo is regarded as a crazed menace even by most of the other supers at Whateley Academy. Bladedancer has just had to separate herself from all her friends because of her prophetic dreams. And Phase... Poor Phase. He has become a mutant, been kicked out of his mutant-hating family, lost the wealth and protection that gave him, been tortured by a Mad Scientist, been turned into an intersexed mostly-female form, and been sent to Whateley Academy. But his last name (Goodkind) represents everything mutants hate and fear. People come out of the woodwork to attack him, either verbally or physically. sometimes both.
Nearly every major character in Worm qualifies as this trope to some extent, as superpowers in the setting mainly come from a Traumatic Superpower Awakening, which tends to shape their thinking and affect them for some time after the fact. Nearly everyone is dealing with some form of trauma or angst.
There is an ever present yet dignified sadness in Peter Cullen's performance of Optimus Prime, as if The Great War has affected him so deeply, that he is always crying deep inside. Cullen stated in interviews that he drew inspiration from his brother, a Shell-Shocked Veteran of The Vietnam War, who told him before the audition for Optimus "Don't be a tough hero; you are strong enough to be gentle."
It's significantly increased in his non G1 performances, possibly because the Film and Prime versions have Cybertron ruined by the war, whereas G1 still had the hope of things eventually getting back to normal (and indeed they eventually do in the finale). In G1, Prime would occasionally crack a few dry jokes, insult or taunt the cons, and hang out with the bots, watching TV or playing basketball. 2007 and beyond Prime is all business. He'll make heroic speeches and cheer people up, and is badass in battle, but is almost always all business. He also sounds older, not exactly old, but more like a general in his late 40s to 50s, though that's probably because Peter Cullen is 20 years older.
Goliath, if not the rest of his clan, perfectly embodies this trope on Gargoyles.
Aang is the last of his people alive and under tremendous pressure to save the world.
Zuko, as Aang's foil, suffers from his own version. Though a substantial amount of it is self-inflicted and it takes a while for him to accept himself and his actions.
Subverted in Justice League, when Orion thinks that Flash covers this trope, but is proven wrong:
Orion: I understand you now. You play the clown to hide a warrior's sorrow.
Flash: Dude, the bad guys went down, and nobody got hurt. You know what I call that? A really good day.
