Kittan as well, although he did die laughing about how awesome it was (his sacrificing himself to save everyone via a giga drill breaker).
Pretty much everyone who is dead on the good side is this. Hell, even some of the bad guys; this is a World of Badass, after all.
Speaking of bad guys, one stands out. Lordgenome, who not only has a mecha that is stronger than Simon at that point, but he gets out of it to pummel it with his bare hands. The fact he had dominated the fight, and Simon had to use a cheap shot to kill him cements him as this
Darker Than Black: Lives and breathes this tropes. First season had November 11, Mai, and countless others. Second season has had: Tanya, April, and Goran. July however has made it.
July died as well in the second season finale. In general, if you are attached to a character on the show, flip a coin to see if they die or become horribly traumatized.
In the back-story of Gundam SEED the Original Coordinator George Glenn was assassinated pretty much out of jealousy and envy of his awesome and cool accomplishments by the Blue Cosmos faction making him a sort of in-universe example of being too cool to live.
Subverted in Rurouni Kenshin; Kenshin's master is a huge, muscular man who is a master of the style. It even sets him up for dying in this way, as the traditional means of mastering the final technique was to kill your master while using it. However, Kenshin's reverse-blade katana saves his master from certain death, yet Kenshin still masters the technique. His master then goes on to save the rest of Kenshin's band from the minions of Shishio, while Kenshin goes to fight the Big Bad himself. However, he does drop out of the story after the prologue of the following arc to keep him from overshadowing the main characters.
Joichiro Nishi. Not only was he the only guy who seemed to know what the hell was going on, he was smart, badass, funny as hell and something of a Magnificent Bastard at that. So of course, he had to die.
Only Nishi? Perhaps the more obvious case of Too Cool To Live in Gantz would be Kato, who quite a few people preferred to Kurono before the latter's Character Development (thankfully, he comes back in the manga as well). Sakata and Suzuki easily qualify late in the manga as well.
Vanessa and Elenore in Madlax were odd examples in that they were somehow both Too Cool To Live and Too Cool To Die. Their idea of splitting the difference was...interesting...
Jiraiya the Toad Sannin has become this over the course of Part II since his death. Possessing a high amount of Badass skill, his own Super Mode, and being able to fight the Disc One Final Boss and temporarily defeat him, as well as his own wisdom being used to redeem his fallen student through Naruto Uzumaki, its easily to see why he's cool. Even Kabuto lamented his inability to use Edo Tensei on him.
Festa in Fang of the Sun Dougram. He defeats an enemy Humongous Mecha on a bike and saves the titular Super Prototype. Five minutes later he goes for a drive and a grenade goes off in his bike. A grenade that a dying enemy soldier dropped there in the previous episode. A grenade that he conveniently didn't notice at all.
Danny in the Zatch Bell! anime. He's a strong fighter barehanded, and has a spell that can heal all of his injuries (even resurrect him after getting shot to death) limitless times. So he dies in the same episode he appears, in a very stupid way and only to protect a statue.
But like darn near everything else in this series, it's a Tear Jerker anyway.
As a bit of an added punch, the statue he was hell bent on protecting broke before he was in that situation.
Cross Marian in D.Gray-Man necessitated a hunt across half of Asia by the Black Order, then sauntered in and saved Allen's ass on the Ark. His superiors at the Black Order were not amused by his tendency to go truant and put him under house arrest, and he spent quite a while lounging around headquarters, seducing women, racking up insane amounts of debt on the Order's tab, and completelyoutshiningeverydamnpersonin thewhole place, as was aptly demonstrated when Lulu Bell attacked. But then, he suddenly, mysteriously disappeared with very little evidence how; they Never Found the Body, and it's undoubtedly going to factor into the plot later, as it's well established that he's hard to take down.
Although because he was apparently shot in the head in a way that nothing human could have survived, and all the blood found at the scene was confirmed to be his, chances are he's either genuinely dead, or not human.
Yuuko from Xxx HO Li C is so cool that Clow Reed warped reality to delay her death before she died for real.
To elaborate, when Ace was younger and hung with Luffy, he was already stronger than the latter with a Devil Fruit, while the former was Badass Normal beforehand. Not only was he was the third strongest person in a crew said to be the strongest in the current era; capable of fighting with a Warlord to a draw, he was also a much more well rounded person who easily surpassed Luffy in charisma and ability it took the most unfettered of the Admirals to kill him after a long battle to rescue/execute with basically almost every superpower aside from a few notable people
In Soul Eater, Mifune. Yes, his death allowed Black Star to find his own 'path' and all, but damn wasn't that samurai guy cool. Plus he left behind cute little witch Angela.
This is, in fact, one of the ways in which the Gecko Ending of the anime improved on the manga. He survives and ends up going over to the good-guy side (can't really call it a Heel-Face Turn since he was never evil in any sense of the word).
While not as awesome as Mifune, the manga also has BJ. Nifty soul perception skills, he and Marie had a history, and member of a different part of Shibusen - Internal Investigations. He was every bit as weird as the rest of the staff...killed off within three chapters.
And now, possibly, Tezca the South American Death Scythe (the bear guy). Okubo seems to get steadily more bizarre with his characters, and the Demon Mirror could have been fun to watch had he not seemingly been offed by Justin Of course, he ''is'' a mirror...
This was almost played straight with Joe Asakura aka Condor Joe in Science Ninja Team Gatchaman; he would have died and stayed dead if there wasn't a second series in the works, and early planning for the second series had him Killed Off for Real and replaced by an android (while another draft had him resurrected as a villain and replaced by a never-before-mentioned brother). In the end, the trope was subverted by having him just barely survive, then implanted with cybernetics.
Claymore gave us Teresa of the Faint Smile. She's a major fan favorite, but she's so overwhelmingly powerful that she'd inevitably overshadow everyone else if she were allowed to stay, including her adoptive daughter Clare. Word of God has it that if she'd survived her battle with Priscilla or been revived later, the entire story would have been different.
Vegetto (Vegerot in the VIZ translation) from Dragon Ball Z. Yep. Guy comes, dominates Buu-Gohan (In his base form in the anime, he just transformed for kicks.), even when turned into the world's most powerful candy, he lets himself get eaten by Buu so he can go save his friends. Unfortunately, he unexpectedly lets down his protective barrier and defuses.
Anchan from Rainbow Nisha Rokubou No Shichinin. This guy is looked up to by the other 6 main characters, including The Hero, after he completely tears them up in a 6 on 1 boxing match in a prison cell. He's also extraordinarily durable. He lives through nearly being burned alive in a locked cell, and being starved and paralyzed with ice cold water until he could just barely see those white pearly gates as his friends carry him in an epic prison breakout, only to die from a stab wound and a barrage of bullets while on his way to see Mario's Heroic Rematch.
Leomon and his subspecies in every Digimon series in which he's an ally.
Cho-san from 20th Century Boys, the detective so awesome had he not died he would have resolved the plot of the entire manga 21 in-series and 7 real-life years earlier than without him.
In her first appearance, Mami Tomoe summoned a thousand rifles and wiped the field of Mooks from space. She then took Madoka and Sayaka under her wing. 3 episodes in, she's violently decapitated and devoured by a witch gone One-Winged Angel. Also qualifies as Too Happy to Live, since she had literally just pledged her friendship to Madoka.
Daguza Mackle, aka Commander McAwesome, from Mobile Suit Gundam Unicorn. Even his death was awesome: He jumps out of the Unicorn with a rocket launcher, shoots the Sinanju in the head in an attempt to blind it, and salutes to Banagher one last time before being incinerated by the Sinanja's beam axe.
Fujimoto of Blue Exorcist, despite only being there for a two episodes/one chapter. He was the most powerful exorcist in the world, holding the rank of Paladin before he died. And he has a cute familiar that looks like a cat.
Zoalord Purgstall from Guyver caught on with fans for being a badass, honorable, caring guy who happened to be on the antagonist's side. Fans still cling onto to hope he'll somehow come back from the dead.
Tatsugoro, Otose's late husband, in Gintama who was an honorable, upstanding, all-around-awesome guy who fiercely defended his town, who got the girl and who was able to fight the baddest punk in town (who later became the yakuza boss and one of the four emperors of Kabukichou) to a draw. Of course he goes and dies, taking the bullet for that punk (who was also his friend and rival for the girl), which set in motion opposing set-in-stone promises from two of the series' most stubborn characters, Jirochou and Gintoki.
Spike Spiegel from Cowboy Bebop is the main character version.
Although not even Word of God knows whether he's really dead or not.
In Samurai Deeper Kyo, we have Muramasa, Taihaku, Fubuki, and most definitely Hishigi. One could also make an argument for Kyosaburo (also known as the Toudai Aka no Ou), a Posthumous Character who created the Mumyo Jinpu Ryu, techniques capable of killing God (the Sendai Aka no Ou).
Code:Breaker has Hitomi and Code:Seeker, who were both killed at the end of their arcs.
Hunter × Hunter has Uvogin who killed three well skilled Nen users with only while paralyzed from the neck down. For the plot, he served as Kurapika's starter enemy from the Genei Ryodan as the physically most powerful member, so Kurapika found out that he can defeat the members in terms of raw powers.
Kite, Netero, and Meryuem, the last one was even the most powerful being who was born in earth.
Examples abound in Jojos Bizarre Adventure thanks to the series taking place in a World of Badass and every storyline having at least one Hero Killer who racks up a sizable body count before they're taken down, but in particular it really sucks to be a Zeppeli. Will A. Zeppeli from Part 1 acts as The Obi-Wan to Jonathan before he's killed by Tarkus, and in Part 2 it's revealed that he had a grandson named Caesar who becomes The Rival and Lancer to Joesph, only to eventually fall to Wamuu. With the Zeppeli line seemingly wiped out, it takes a quasi-reboot in Part 7 to bring us Gyro Zeppeli, the storyline's Deuteragonist...who doesn't survive to the end, either.
Rorschach from Watchmen, who would prefer that Dr. Manhattan vaporize him rather than let himself willingly abandon his moral code.
Lord Voll in ElfQuest. He would have been a Cool Old Guy father figure to all races of elves, laughing and flying around while guiding them in unlimited space travel and bringing about worldwide harmony. A single troll arrow kills him. In the end, it takes the elves another 1500 years to achieve what he could have given them in a day.
Marv from Sin City, whose only starring role in a full-length story basically serves as one big Heroic Sacrifice and ends with him dead in the electric chair.
And Blink, especially considering very shortly after her death, an incredibly Bad Ass alternate reality version of her was depicted in significant detail.
MVP, from Avengers: The Initiative, gets a lot of focus in the first issue as clearly being the best of the new trainees. This is made doubly-impressive when you find out he has no super powers. At the end of the first issue, his death signifies that this is not a perfect program for perfect candidates, and that this is going to be a story about the more troubled kids.
In a less action-y way, Qui-Gon probably fits. Had he survived to be Anakin's mentor (as was the actual plan), the rest of the series probably wouldn't have happened due to his extreme level-headedness and wisdom.
Yoda admits as much (at least to himself) in the novelisation of Revenge of the Sith, declaring to Qui-Gon's ghost that Qui-Gon's bend-the-rules-and-adapt mentality had been correct all along and he (Yoda) had essentially led the Jedi to disaster.
Joe Brody in Godzilla (2014). Narrowly subverted with Godzilla himself in the final battle.
Hero, Heroine, and Jason Mewes in Feast. The former survives about thirty-five seconds of screen time before being messily eaten. Heroine lives for most of the movie, is extremely resourceful and helpful, but also dies. Jason Mewes gets his face ripped off in the first ten minutes.
Captain Kaneda in Sunshine. He's professional, he's pragmatic, and he cares deeply for the success of his crew's mission. Plus, he's played by Hiroyuki Sanada. If he hadn't died within the first half-hour, he'd probably have broken the plot.
Doc Holliday from Tombstone. Granted it's based on a true story, but still.
Subverted in Zombieland when it looks like resident Bad Ass Tallahasse is going to be killed off during the shootout at Pacific Playland. Instead, he's too cool to be too cool to live. His coolness wraps around itself to defy trope conventions.
Not just the human characters: Striker Eureka performs a nuclear flavored Heroic Sacrifice to clear the way for Gypsy Danger. This trope applies to all Jaegers but Striker Eureka stands out due to its heroic looks, statistics and combat record.
Parodied in The Other Guys, where Danson and Highsmith, two Badass policemen, deliberately jumped off a tall building while chasing jewelry robbers in the hopes they would land in the bushes. They didn't survive.
Brian could become an example in Fast and Furious 7, for the same reason mentioned directly above.
Garet Jax in The Wishsong of Shannara. The man is called a "weapons master" because no matter who his opponent is, and what weapon he uses, he will still manage to pull off a crowning moment of awesome and come out alive. Well, until he defeats an ancient Eldritch Abomination in a heroic sacrifice.
Both Thomas and Pug from the The Riftwar Cycle have become too powerful to be sufficiently challenged by the threats that often appear in the later books. As such they are often described as being elsewhere or just missing.
Inigo Skimmer is the best damn character in The Fifth Elephant (beyond Vetinari, who is, to be fair, employing him). He's also an absolutely superb fighter and Assassin. Sadly, when he's attacked by a large group of werewolves, not superb enough. One of the best Discworld characters, and he only got through half a book. Tragic.
A Song of Ice and Fire: Syrio Forel, Beric Dondarrion, and Oberyn Martell, the Red Viper of Dorne, to name a few.
Eddard Stark however is pretty awesome and his death sets the tone for the whole series brilliantly.
Fittingly, in the HBO adaptation, he's played by Sean Bean, who tends to play these sort of characters a lot.
And Khal Drogo. His actor in Game of Thrones was so upset that the character got killed off that he proposed to the showrunners that a Backup Twin could show up in the second season. They worked him into the season finale, albeit in a different way (from beyond the grave).
Qhorin Halfhand. Too badass.
Oberyn Martell deserves a special mention - the guy certainly gained a huge following while he was around.
Everworld has a character with the appropriate name of MacCool who fits the trope very well for a minor character. MacCool is an elf who is a romantic rival to Christopher, and as his name implies, his characterization mainly consists of being cooler and more impressive than Christopher. He dies fighting against a danger very unfamiliar in Everworld: humans armed with machine guns. And of course, there is a perverse satisfaction in the fact that Christopher was the one who had known about the gunmen and how to protect against them, but MacCool didn't follow his instructions.
Roy Meritt from Daemon. His status transcends death, being revered by Darknet operatives well into the sequel.
Bridge to Terabithia: poor Leslie. This is intentional, as this book is Based on a True Story of how the best friend of the author's son was suddenly killed by lightning, AND she is described as remembered by Jess and others, thus looking cooler than she would otherwise.
It was a wonder Albus Dumbledore made it as long as he did. Also Sirius Black, Tonks, Lupin and Moody.
In the timeline of World War Z, General Raj Singh narrowly escapes this trope (unwillingly—he rediscovered tactics that would have worked against the Zombies with enough ammo, and has to be punched unconscious to be 'coptered to safety), only to play it straight during an evacuation—by manually detonating the bomb on a mountain pass, so that the safe zone remains ghoul-free.
Chris dies at the end of the second series of Skins.
The BBC's Robin Hood introduces Meg, a smart, spunky girl who shows intelligence, compassion and an endearing sense of entitlement that gets Guy of Gisborne to stop moping and rethink his priorities. Meg's counterpart Kate spends the entire episode sulking and moaning (as per usual) and tops it off by trying to manipulate a dangerous situation so that her romantic rival is killed off. Now, guess who dies and guess who survives the entire show.
Victor from Burn Notice. He's as intelligent as Michael, he plays off Michael's personality very well, he would be very useful and interesting in Michael's day-to-day jobs, he is funny, he is played by Michael Shanks, and he dies in the episode where he teams up with Micheal.
Alas, poor Peggy. When the battlestar Pegasus shows up halfway through Season 2 of Battlestar Galactica, she was doomed from the start by virtue of being a more advanced and awesome battlestar than the Galactica. And so, alas, she was taken from us far too soon, at the hands of recently-promoted (idiot) Commander Lee Adama - after only appearing in any significant roles in a couple of episodes before her demise. Because Ramming Always Works.
Vikings: Erik, a towering, heavily muscled Viking warlord who hewed apart Saxons with a single strike, who sent men flying with a single shield bash, and who was played by Vladimir Kulich, is this in spades. He was mourned, both in universe and out. His death also spurs the main character to bring down the despot Earl who rules the tribe.
Game of Thrones: Khal Drogo and Eddard Stark are probably the two biggest examples from the tv series, at least so far.
Jory, Ned Stark's right-hand man and Yoren, the recruiter for the Night's Watch are also suitably awesome, before dying shortly afterwards.
There are so many examples of this present, it has led to some fans jokingly suggesting that the show could easily be renamed, "Too Cool To Live: The Series".
This trope could conceivably be renamed "The Oberyn" without any problems.
There's no way Dollhouse could keep Bennett around. She's just too damn distracting.
The white-haired British guy in Stephen King's Rose Red. Level-headed, brave, not too bad-looking, and friendly with the rest of the characters, even the crazy leader who, like a certain Jack Torrance was way too comfortable in the sapient, giant, evil house — yup, he was doomed.
What makes his death a real shame though was that he died saving the life of a woman who was stupid enough to leave the group in middle of a house that was trying to kill them. And why did she leave? She wanted some iced tea.
Adam Monroe from Heroes definitely fits this trope.
The Ninth Doctor from Doctor Who, who's the second most short-lived Doctor after the Eighth Doctor (who has the excuse of being in a TV movie), in spite of being concentrated amounts of eccentric awesomeness.
Really, all the Doctors, being Crazy Awesome, qualify to a certain extent. They all get replaced by another awesome incarnation right after regeneration, though, so it's all good.
The Tenth Doctor may fit this trope more as he might actually have been the shortest lived Doctor in canon since he is conformed to have only lived for 6 years whilst other incarnations such as the 11th and 1st are known to have lived for centuries.
Father Octavian, from the 2010 series. Iain Glen really is just THAT awesome. Even the Doctor is genuinely bummed out by his death.
Mrs. Moore from Rise of the Cybermen/Age of Steel also qualifies.
Rita from The God Complex is intelligent, competent, witty and all-around awesome, to the point that the Doctor jokingly tells Amy she's fired as his companion within a few minutes of meeting her. She is so very doomed.
While Bryce Larkin might not be the most sympathetic guy in the series, he is certainly much cooler than the lovable loser the main character is at the beginning of the series. Accordingly, he is killed in the pilot. He gets better.
Sokichi "Boss" Narumi from Kamen Rider Double, a hard-boiled detective who lives by the ideal created by authors like Raymond Chandler and who radiates awesome and badass from every single fiber of his being, but deep down still has his soft side. And all this is before you factor in that he's also a Kamen Rider. To put it simply, the Boss is a smooth criminal.
Lawrence Kutner and possibly Amber Volakis from House.
Kristina Kell in Survivor: Redemption Island was probably the only player besides Rob on the Ometepes who had a brain. First thing she thought upon seeing the return of Boston Rob and Russell Hantz? Rob's gotta go ASAP. She proceeds to find a hidden immunity idol before the first tribal council with no clues. A show record. Unfortunately she's voted out fourth and booted early, ending hope of anyone interesting from the Ometepe tribe going far.
Kristina definitely had a bunch of enemies in the editor crew - She only got screentime when she was shown finding the idol, during tribal council, and on redemption island. The "recap" before the finale conveniently glossed over how Kristina caused a schism in Rob's tribe so early, and Probst didn't even so much as look in her general direction at the Reunion show.
Several characters on LOST. Mr. Eko steps out though because he died so early on and with so little time on the show.
Godric from True Blood was arguably cooler than the main cast. Naturally, he dies just a few episodes after his introduction.
This happens frequently on Merlin what with the writers' remarkable gift of writing fascinating One Shot Characters, casting veteran actors to play them, and promptly killing them off. Notable examples include the druid Aglain (played by Colin Salmon), the Warrior Monk Alator (Gary Lewis) and the sorcerer Ruadan (Liam Cunningham). That last one was an incredibly rare example of a magic-user who was opposed to Camelot and the Pendragons, but not overtly evil, making his death all the more frustrating. There was also Finna, a Badass Grandma and Isolde, one of the show's few Action Girls.
Tortuga from Breaking Bad. A wise-cracking, rather helpful informant to the DEA and played by Danny Trejo? Obviously can't last for more than two episodes.
Also, an oracle told Achilles that he would either have a long and undistinguished life or a short but heroic one. He chose the heroic one, as we all know.
Pretty much all the Planeswalkers in pre-Time SpiralMagic The Gathering. Planeswalkers, previously, were godlike beings of immeasurable power over not just one world, but all worlds, and the games were supposed to represent their duels (which were more like petty games than actual wars, since they could not be truly hurt). However, Wizards of the Coast realized that this meant that any time a character became popular/powerful enough, they could no longer write stories or make cards about them, and also made it difficult for the players to relate to them. So it was decided to tone down the power of Planeswalkers, and in the process the board was wiped clean, with virtually every existing Planeswalker destroyed.
To give you an idea, post-time spiral, only Nicol Bolas and, later Karn have managed to survive. Venser, the first of the "Neo-walkers", also proved to be to cool to live. Phryexia as a concept has also managed to make it back from the dead, though.
All the Primarchs in Warhammer 40K are dead or ascended in the contemporary setting. As genetically engineered demigods of war, they would unbalance the grimdarkness considerably. They do appear in the Horus Heresy though.
An example from the latter series would be Hastur Sejanus, a member of the Mournival and Horus' best friend. Famed for his even temper and levelheadedness, his death on more or less the first page of the first book is an 'in universe' example of this, as with him around, the first trilogy likely would never have played out this way, since the plan hinged on Horus' feelings of loneliness and abandonment.
Angel in RENT. What can be cooler than a transvestite street percussionist with AIDS?
Final Fantasy XIII got a rare female example in Oerba Yun Fang. Her Australian accent in the English dub only increased her already considerable Bad Ass quotient. Fortunately for the shippers, she only goes into crystal stasis. Fix Fic here we come!.
Kratos, of Tales of Symphonia decides to accompany a giant comet made of mana into outer space at the end of the game, never to be seen again. The big bad is dead, there's no reason for him to go, but he does anyway because he's "A relic of the past."
Damnit Asch if you'd stop overshadowing Luke, you wouldn't be dead now would you?
Zero averted this, thanks to fan outcry over his Heroic Sacrifice. (That, and the creator wanted him to be the new Mega Man but Capcom said no.) Depending on the endings you get, he dies later, but not canconically. In X5, he dies again, but comes back due to more Executive Meddling, and seals himself away at the end of X6. By the end of his own series, he dies permanently...but is brought back as Model ZX in Mega Man ZX along with the Guardians.
Wodan Ymir from Super Robot Wars. So imagine that you've got the awesome Sanger Zonvolt, and then you CLONED him, and said clone inherits ALL his awesomeness. Can the universe keep itself from imploding with the awesomeness those two emit? The clone gotta go.
Nihlus Kryik from the first Mass Effect. Bad Ass Spectre, intrigued by the potential of the human race, clearly established as a mentor for Shepard, dies thirty minutes into the game. Samara (from the second game) describes how he outwitted her after a two week game of cat and mouse: namely, turning her own Code against her. Bear in mind that Samara is a thousand year old asari Justicar that started fighting injustice around the same time Napoleon was marching on Moscow.
Samara and Morinth. Whichever one dies definitely counts.
Thane Krios and Mordin Solus from Mass Effect 2 are both very popular with fans and highly likely to die during ME2's suicide mission; Thane is terminally ill and Mordin is at a fairly advanced age for a member of a race with a 40-year lifespan, and neither character's skillset is well-suited to front-line combat. If they make it to ME3, Mordin is all but guaranteed to die during the mission on Tuchanka unless a very specific set of requirements (one of which is killing off another former squad member) is met, and Thane inevitably dies stopping Kai Leng from assassinating the salarian councilor.
Also in Mass Effect 3, Legion dies no matter how the situation on Rannoch is resolved, either committing a Heroic Sacrifice to help save the geth, or going berserk and forcing Tali to kill them in order to save Shepard.
Depending on your opinion on the characters, any member of the team in Mass Effect 2 if you haven't completed their loyalty missions (and sometimes even then).
Since Namco enjoys teasing their fans, the director's cut of the remake includes a New Game+ option to play through the game following Leon as the main character instead of Stahn. Fans were hopeful that there would finally be a story path where he wouldn't be too cool to live. Nope, he still dies, and the game ends there.
In the Halo series, Sergeant Johnson appears to fall into this trope twice, but survives off-screen the first time around.
Comes up again with all five members of Noble Team in Halo: Reach. To clarify, the dead characters are the elite squadron commander, the girl with the robot arm, the guy with the skull on his faceplace, the guy using a turret as his primary weapon and the main character who spends his/her last minutes trying to hold off the entire Covenant army. Too Cool To Live indeed.
Johnny Gat spends the first two Saints Row games establishing himself as a Crazy Awesome badass, only to die in the first half hour of Saints Row: The Third. Part IV reveals that he was in fact Too Cool To Die, and he actually survived the events of the third game.
Advance Wars: Days of Ruin features the grizzled, experienced, charismatic, and tirelessly selfless Captain Brenner, the undisputed commander of his unit of heroic soldiers, and, for all intents and purposes, the protagonist of the first half of the game. Since the younger, far more BishōnenWide-Eyed Idealist newcomer Will has to have some plausible reason to take the mantle from Brenner....
E-102 Gamma from Sonic Adventure... and then his parts are used to create E-102r, a.k.a Chaos Gamma... and then he gets an extremely badass "younger brother" E-123 Omega (who was first voiced by JonSt. John, of course.)
In Baten Kaitos Origins, party member Guillo is a total Badass, a hilarious Deadpan Snarker, a big Game Breaker in combat, and has a compelling backstory. It sacrifices itself almost immediately after the final boss to save Sagi from a malfunctioning machina.
Ghost from Call of Duty: Modern Warfare 2. He was all around a badass special forces mofo, but the thing that really set him apart was his iconic skull mask. He was killed off rather unceremoniously, however the fan reaction to him was so strong that there was talk of making a spinoff game starring him. The game seems to have been scrapped, however he did end up being included in Sony's ambitious Intercontinuity Crossover commercial Michael.
Trevor from Phantasmagoria 2 wasn't cool in the traditional sense, but he was still the most likeable character in a cast full of assholes and Too Dumb to Live idiots.
Mia Fey in Ace Attorney. So awesome that it doesn't even take - she keeps being channeled through the Phoenix arc by her younger sister and later her cousin.
It's not so much canon as firmly implied that he won't live long, but Godot.
Who else could become a Ensemble Dark Horse post-death than prosecutor and noble thief Byrne Faraday?
Sakura Oogami from Dangan Ronpa. The Super High-school Level Wrestler with the buffest body among all of the students trapped at Hope's Peak Academy; though strong and intimidating, she was also level-headed and polite. It also happened that she was The Mole for Monobear, who outed her to the rest of her classmates, which led to them growing distrustful of her. As such, she poisoned herself with intent of uniting the students against their common enemy after her death, and also broke the lock of the headmaster's office; proving instrumental in providing the group vital information.
Archer in Fate/stay night. Many say the same of Lancer. Heck, pretty much every Servant qualifies.
Amon/Noatak from The Legend of Korra. He learned how to bloodbend outside of the full moon with his mind by the age 14. At the same age, he left home and went into a raging blizzard by himself and made it out alive. When he was revealed to be a waterbender, his bending was shown to be especially badass. Then Tarrlok blew up the boat they were on. It's understandable considering that no matter how much he could change, he'd still always be broken, but still, it's sad to see such a badass like him go.
Book 3 ends with only the least overtly showy and spectacular Red Lotus operative surviving long enough to go back to prison...and he's the Big Bad.
Tigerhawk in Transformers: Beast Wars is also the latest of latecomers, being only in a handful of episodes. Sell those toys!
Also in TFA Prowl. Just when he's mastered the cyberninja arts and and has become totally awesome, he sacrifices himself to save Detroit.
Also in TFA, Blurr. A very competent secret agent who's able use his superspeed to curb stomp squads of Decepticons. Too bad The Mole realized Blurr was about to blow his cover and had to dispatch him (according to some cut material, he may still be alive...)
The newest member of the too cool to live Transformers club, Cliffjumper from Transformers Prime. Awesome car form? Check. Has cool viking horns on his head? Check. Voiced by The freaking Rock?! Check. Dead before the second commercial break? Check.
Skyquake, a Decepticon version of this Trope, could be considered the Decepticon version of Cliffjumper.
Nabu from Winx Club. Seriously! On top of being an incredibly sweet and nice guy, he managed to single-handedly take out Duman and close a powerful magical portal that would've sucked all of the Earth fairies into oblivion in just one episode…only for him die after using up all his energy. None of the other Specialists ever reached the level of Badass that he did and they have had twice as much screen time. Even though he appeared in the second movie, it seems he is still dead as of season 5.
