Accidental Hero
Nothing convinces one not to commit suicide better than accidentally saving a baby while trying to.

Yakumo: Wow, that's impressive.
Tenma: That's not what was supposed to happen at all!

A character becomes celebrated for heroism. Problem is, it isn't false modesty this time. He really didn't do anything special.

Two flavors:
  • The accidental hero blundered in some way that actually caused a rescue or saved the day.
  • The accidental hero was just standing around in a place where it looked like he saved the day.

In either flavor, public acclaim that just won't go away is the main complication. The subsequent plot is a good showcase for examining the fiber of the accidental hero's character and to spin a little yarn about how people ''need'' heroes. Many times he becomes a true hero by the end of the story.

May be a consequence of Non-Protagonist Resolver. Compare And You Thought It Was a Game, Badass on Paper, Cowardly Lion, Framed for Heroism, God Guise, Nominal Hero, Mistaken for Badass, Spanner in the Works and Nice Job Fixing It, Villain!. May result in Broken Pedestal.

This trope is the spiritual opposite of Nice Job Breaking It, Hero!.

  • In the first Yes! Pretty Cure 5 movie, the Big Bad has the MacGuffin in hand... but it's not complete, so it can't grant any wishes. Blame Urara, who still had that last Pinky and hadn't put it in yet.
  • Carr Benedict in Allison & Lillia agrees to take sole credit for the history-changing discovery made by Allison and Wil, when he was only present because he'd been trying to shoot them. The newly-promoted Major Carr finds the resulting mass adulation and jealousy deeply uncomfortable. His reckless actions in the next adventure (which he secretly hopes will bring his rank down a notch or two) only cement his heroic reputation.
  • In the first chapter of Whistle!!, the main character switches schools and is mistaken for a soccer star by his new team. He doesn't have the confidence to correct them, causing him to be outed embarrassingly when they actually make him play, and he's terrible.
  • Kitano, the protagonist of Angel Densetsu, half the time manages to do this by just being around and not understanding what's happening. The other half, however, he's actually saving the day.
  • Irresponsible Captain Tylor - While he does not really become celebrated (although he gets quite the reputation amongst the enemy), Justi Ueki Tylor does seem to hit both flavors often.
  • In Uchuu Kyoudai, Mutta accidentally foils a robbery and briefly becomes a celebrity.
  • In One Piece, Usopp manages to fulfill both flavors at once in Dressrosa when he is force-fed the Tatababasco-laced bon-bon, causing Usopp to freak out from its spiciness and morph his face so grotesquely that his adversary falls unconscious from shock, undoing her curse on thousands of people, some of whom had been waiting for her defeat for a decade. From the perspective of anyone outside the small room where the battle took place, however, it looked and sounded like Usopp was kicking major butt and emerged victorious after it went quiet.
  • In Toriko, Zebra is hailed as a hero by a small desert village since his earlier rampages ended the war that ravaged the village. And by eating 26 species to extinction, he inadvertently saved the ecosystems said species were destroying.

  • A lot of characters and fans from Dragon Ball Super has called out Goku for setting up the Universal Tournament just to have a good fight that would cause the whole universe to get wiped out if they lose. However, episode 80 later reveals that Zen'O was planning to wipe out the universe anyway because of their low mortal level and by hosting a tournament, Goku inadvertently end up giving the universe a chance to survive. Not that Goku cares anyway considering his complete non-chalant reaction at the thought of universe being erased.

    Comic Books 
  • Disney - Mickey's pal Goofy has been an accidental hero so often that it became a cliche in 1960s comics. Goofy would set out to engage in some hobby or sport, capture a small-time crook by mistake, and then use the inevitable reward money toward the hobby. Every. Single. Time.
  • An Archie comic had Jughead failing as a security guard until he tripped and fell on a guy who turned out to be a shoplifter.

  • The Avengers - Hardball was recruited into the Initiative when he used his powers to save a little girl from being hit by an armored car — at least, that's what it looked like to witnesses. In reality Hardball was trying to rob the armored car. The rescue was a coincidence. This is one of the first hints that Hardball is a bit too amoral for a superhero-in-training.
  • Quite often the Incredible Hulk isn't actually trying to do something heroic, but he often does a lot of good with his powers anyway.
  • Quantum and Woody's first case was an investigation into the murder of Ed Palmer's wife.

Unfortunately, he had nothing to do with the murder — Mrs. Palmer was killed by her husband, as the police had originally surmised.

    Fairy Tales 
  • The Valiant Little Tailor is one of the fairy tales recorded by The Brothers Grimm, in which a tailor's story of killing "seven with one blow" (that is, seven flies) accidentally gains him a reputation as a fearsome warrior, leading him into a series of deadly encounters with giants and other magical creatures. Disney adapted this story as a Mickey Mouse cartoon in 1938.

    Fan Fic 
  • Calvin unintentionally and unknowingly stops an Alien Invasion with a firecracker in Calvin and Hobbes: The Series.
  • The Pony POV Series has an example in Clover's story in the 7 Dreams/Nightmares collection: Clover's about to be killed by her Big Bad, the Diamond Dog Fluffy the Terrible (yes, really) in a shack atop the Canterhorn mountain, when the dragon Bahamut just happens to land right on top of them (he literally didn't notice the shack until after he crushed it), sending Fluffy off the side of the mountain to his death.
  • Accidental Hero Of The Galaxy: Given that it's Mass Effect done in the style of Ciaphas Cain, this is to be expected. Shepard in this missed the last shuttle off Elysium and when the Batarians attacked tried to run, inadvertently causing the Batarians to follow him back to Alliance reinforcements, which allowed them to win the day. Since then, he's been stuck with an evergrowing reputation for heroism he feels he doesn't deserve.
  • And of course, "Mr. Black" from Make a Wish, where young Mister Potter is simply "a guy on vacation" while the bad guys are dying like flies whenever he's in the vague vicinity.
  • The Lord of the Rings fanfiction Nine Men And A Little Lady has Gollum, who inadvertently saves the day by eating Mary Sue, having mistaken her references to her "precious" as meaning the Ring.

  • The Mariachi in El Mariachi came into town just to find a place to play music and get some cash. Instead, when his guitar case is switched with a guitar case full of weapons owned by an infamous hit man, the villains and the Distressed Damsel mistake him for the hit man. Dumb luck allows him to kill the hit squad sent after him, elevating him to legend status.
    • Though after the tragedy of the movie's end, the Mariachi would undergo a transformation over time into the gunslinging vengeance-driven badass that we would see in Desperado, a figure more than worthy of the legend.
  • In Army of Darkness Ash both invokes and subverts this trope at different times.
  • Played with in the movie Accidental Hero (also known as simply Hero): the actual person who saves the people from a burning plane is a Jerk Ass who has one moment of decency (a plane crashes in front of him and he grudgingly helps the victims get out). The bum who (falsely) takes credit for said rescue is otherwise the kind of person you'd believe to be a hero and uses his reputation to help other people. There's enough gray area between them for the audience to decide which (or both) is the true hero.
  • Juan, one of the Villain Protagonists of Duck, You Sucker!, a Mexican highwayman/rapist/murderer, ended up becoming a revolutionary hero after knocking over a bank and inadvertently releasing the political prisoners being kept in its vaults. The gold deposits had been moved out of there months ago, and Sean, his "friend," neglected to mention that to him when helping him plan the "robbery."
  • Forrest Gump is of a sort. Forrest ran back into the combat zone to try and find Bubba, only to be called upon by other soldiers to rescue them, which he did by carrying them to the river. What he did was technically heroic but he didn't intend to save 4 others and be awarded the Medal of Honor.
  • In Star Wars The Phantom Menace, Anakin Skywalker gets into Naboo fighter ship to avoid a firefight in a hanger on Naboo. After accidentally activating the autopilot, the ship flies to the scene of the space fight, where Anakin figures out how to turn off the auto pilot. In an effort to escape being blown up by federation fighters he flies the ship into the hanger bay of the enemy federation ship. After several robot droids notice him and start approaching his ship, he fires on them, destroying the droids. Conveniently, several of Anakin's missed shots at the droids hit a power system structure, which happens to be directly behind the droids. Anakin narrowly escapes the erupting federation ship, which is noticed by other Naboo fighters. "There's one of ours out of the hanger." After the federation ship is destroyed by Anakin's bad aim, the battle is over as without the command and control from the federation ship the attacking droids all shut down.
  • The heroes of the parody westerns The Paleface (Bob Hope) and The Shakiest Gun in the West (Don Knotts) are Accidental Hero material of the second variety. Both men succeed in "saving" a convoy of covered wagons, but the real heroes are their girlfriends (secretly US agents in disguise).
    • Nearly every movie starring Bob Hope or Don Knotts is an Accidental Hero story. A lot of the Danny Kaye movies fit this trope too.
  • In Charlie Chaplin's Modern Times, Chaplin thwarts a prison break by dodging bullets and pummeling the escaping prisoners. But he only does so because earlier he'd unknowingly sprinkled cocaine all over his lunch that another prisoner had hidden in a salt shaker, and was completely high at that point.
  • In Amistad, when they speak with the leader of the Africans through a translator, they learn that he isn't all that confident about "leading" anyone: he became leader of the group because he killed an attacking lion with a thrown stone some time back. He doesn't feel deserving of the acclaim he got for this achievement because the stone was lucky shot that just happened to hit the lion's head in such a way as to kill it; he'd thrown it out of desperation and panic in the heat of the moment.
  • Godzilla's actions in the final act of Godzilla (2014) saved countless lives; killing the Mutos saved what remains of San Francisco and stops what could have been a global epidemic of their species.
    • Although the film leaves it an open question how much Godzilla does that intentionally and how much it's just instinct, so this may or may not be a subversion.
  • In Footloose, the hero is challenged to a Game of Chicken in a tractor, and finds himself the accidental victor as his shoelaces get stuck in the gearing, preventing him from bailing out.
  • During the Final Battle of Jurassic World, the Indominus Rex is getting beat around when the park's Mosasaurus lunges out of the lagoon and drags the I. Rex to her doom. To her, the I. Rex was nothing more than a convenient midnight snack.
  • He Was a Quiet Man: Bob Maconel was planning on Going Postal in his office building, but a similarly withdrawn co-worker beats him to it by roughly a minute. Bob shoots the co-worker with the gun he was carrying at that moment, and is suddenly hailed by his company and the media as a hero.
  • Ghidorah, the Three-Headed Monster:
    • Godzilla and Rodan's battle destroys a power line tower and triggers a blackout, mere seconds before Princess Selina would have been fatally electrocuted.
    • A stray blast from King Ghidorah triggers an avalanche that buries the assassins' car and kills all but one of them. Later, another stray blast causes the final assassin to fall to his death.

  • Audrey, Wait!: The media latches on to Audrey as the subject of infamous Ear Worm and Breakup Song, "Audrey, Wait!", turning her into a celebrity for no real reason other than inspiring the song. Not "heroic" in the traditional sense, but Audrey uses the media attention to good ends.
  • Harry Potter is credited with defeating Voldemort as a baby, when it was really his mother's love that saved Harry and destroyed Voldemort's body. Allowing Harry to grow up without all that pressure is one of the main reasons Dumbledore arranges for him to live with Muggle Foster Parents (even if said foster family went a little too far the other way.)
    • In Harry Potter and the Order of the Phoenix, the nervous Ron is applauded for making a save with his foot during practice. When Harry mentions this right before the first match of the year, Ron tells him that he fell off the broom and kicked it accidentally. Harry quickly quips, "Well, a few more accidents like that and the match is in the bag."
  • In Warhammer 40,000, Sandy Mitchell's Commissar Ciaphas Cain, HERO OF THE IMPERIUM! claims that this is basically what he is in his memoir (ie. the novels and short stories). It's only partly true. In his first short story he was nothing but, credited with saving the day while allegedly scouting for and finding a Tyranid flanking attack — when he was actually trying to desert; and saving his future aide, by charging to protect him from a horde of Tyranids — when in reality, he was simply running from more, larger Tyranids in the other direction. Since then, a combination of his survival skills, extreme good luck, and diplomatic abilities has resulted in him getting out of one hairy situation after another, with his reputation as a HERO OF THE IMPERIUM snowballing. However, only some of this had him accidentally being a hero. Other times, he'd do it on purpose, even if it was only because his own skin was among those needing to be "heroically" saved, or because of his being Slave to PR. He did like that reputation.
  • Everything Rincewind ever did in the Discworld novels that didn't involve running away like his backside was on fire.
    • Except for the one time that he mans up, in Sourcery. But it's okay! The statue, as a reward, gets downgraded to a plaque, gets downgraded to a certificate, gets downgraded to a fine.
      • It's implied that although a coward he may be, Rincewind also grew up on the streets of Morpork - and Survived. Which is why he chose a half-brick in a sock as his weapon against the greatest Sourcerer to ever live.
    • Also in The Light Fantastic and Interesting Times, although he is still trying to run away in Interesting Times. He just finds the save-everybody MacGuffin while he's at it.
    • As Lord Vetinari remarks in The Last Hero, "[T]he thing about saving the world, gentlemen and ladies, is that it inevitably includes whatever you happen to be standing on." One of Rincewind's enduring character traits is his willingness to "heroically" face almost certain death whenever the alternative is facing absolutely certain death.
    • The title character of Eric. He had intended to summon a demon from the Dungeon Dimensons to grant his wish. He ends up rescuing Rincewind instead.
  • There's an element of this in The Wonderful Wizard of Oz, after Dorothy's house squishes the Wicked Witch of the East, and it's the key to the plot. Without squishing the Wicked Witch of the East Dorothy would never have acquired the Silver/Ruby Slippers and incurred the wrath of the Wicked Witch of the West. Nor would the Wizard have assumed she was powerful enough to destroy the WWW and thus never would have sent her there.
  • In the Warrior Cats graphic novel Rise of Scourge, we learn that Big Bad Scourge became the ruthless warlord he was in part by trying to live up to a reputation for toughness he got for beating up two dogs. One of these incidents was a complete fabrication and in the other the dog became afraid of Scourge's shadow and ran off while Scourge was yowling at him. Of course, Scourge apparently did kill a few dogs for real later.
  • During the war in Lois McMaster Bujold's Shards of Honor, Cordelia gets all the credit for killing Admiral Vorrutyer. She protests, but not too strongly, because she's protecting Sergeant Bothari, who would get court-martialled if his side knew he had done it.
  • In John Gardner's novel The Liquidator (made into a movie in 1965), a WW2 soldier called Boysie Oakes mishandles his sidearm and kills two men. Fortunately for him they are both German agents. This seen by the Allied agent they were trying to kill who mistakes his terror-stricken gaze as a stone-cold killer face. The agent later recruits the soldier as an assassin for British Intelligence.
  • Subverted in All-American Girl, where the main character believes she's this but, in fact, she really did do something heroic.
  • This trope is the title of the first Jack Blank book (in the second publishing run, the original title was Jack Blank and the Imagine Nation), and an accurate description of what Jack did in the first chapter. He's considered a hero for beating Revile the Undying, when all he did was blow up a school generator when he panicked and Revile got caught in the blast. He didn't even know he was a technopath at the time.
  • In The Lost Fleet, Commander John Geary was a commander of a small task force patroling a system near the Syndicate Worlds space. When the Syndics invaded The Alliance, one of the first attacks was on the convoy going through the system. Sending all but his ship to the jump point, Geary turns his ship towards the incoming Syndics in order to hold them off long enough to let the others escape. He evacuates the crew and himself jumps into a cryopod before his ship is destroyed. While the act is definitely heroic, when he wakes up nearly 100 years later, he finds out that the Alliance has turned him to a great hero who will someday return to lead the fleet to a glorious victory over the Syndics. He Alliance-Syndic war has continued without stopping for all this time, with both sides being too large to be easily defeated. Heavy attrition of experienced personnel has resulted in Attack! Attack! Attack! being the only fleet tactic familiar to the fleet with personal glory of ship commanders being the most important thing in battle. Geary is now a full captain with the legendary nickname "Black Jack". However, when someone points out his heroic Last Stand, he explains that this was his only battle to date, and he lost it.

  • In the Firefly episode "Jaynestown," Jayne is idolized by the citizens of a small town who herald him as the hero who robbed their oppressor and gave them the money. What the locals do not know is that the robbery was just that: a robbery. Jayne had every intention of keeping the money, but his ship was damaged and he had to throw the money out the window in order to escape. In fact, he was so determined to keep that money that he actually threw his partner out of the ship first. The spurned partner returns, minus an eye, and reveals the sordid truth, but this does not stop a local man from taking a shotgun blast meant for Jayne. There's even a song that the locals composed in celebration of his "heroics," an excerpt of which can be found on the quote page.
    • Jayne also denounces heroes in and of themselves in a fit of grief after said townsman is killed shortly afterwards, saying there's no people like that. "There's just people like me."
  • Star Trek: Deep Space Nine has the episode "The Homecoming": the Bajoran Li Nalas was hailed a legendary hero after slaying a powerful Cardassian warrior in an epic contest of strength and skill. The truth is that Li Nalas caught the man by surprise——the Cardassian had just finished bathing and was clad only in his underwear, and the impression of a struggle only came about because the Cardassian collapsed on top of Li Nalas after he had been shot. Though he wanted to reveal the truth, he was convinced by Benjamin Sisko that his "deeds" inspired others and, even if it never really happened the way people said, he was the hero that the people needed.
    • Another Deep Space Nine episode, "Nor the Battle to the Strong", has Jake Sisko: a civilian, aspiring novelist and part-time journalist. While on a besieged planet, Jake defended a field hospital by causing a minor cave-in, killing two Klingon invaders and sealing the entrance. Except that it was all an accident, he was panicking and shooting blindly, and the results were extraordinary luck for him. He freely admitted, however, that he was acting on fear and only trying to stay alive. He even wrote a truthful account of it for publication. He may not be a hero, but he's a very conscientious journalist.
    • In yet another Deep Space Nine episode, a Klingon warrior attacks Quark in a drunken rage, and accidentally falls on his own knife. People assume that Quark killed him in self-defense, and instead of denying it, he milks the publicity for all it's worth... until it lands him in the middle of a series of Klingon political intrigues.

  • In an episode of Frasier, Bulldog enjoys this status when he grabs Roz and spins her away from danger when their coffee shop hangout is attacked by a gunman. In actuality, Bulldog thinks that someone pulling out his wallet is the gunman and spins Roz towards him, using her as a human shield. The rest of the episode features Bulldog being lauded with praise for being a hero while Frasier tries to convince him to come clean - starting with simply asking him and escalating into more and more elaborate attempts to guilt-trip him. Of course, him being Bulldog, none of this works. Things finally return to normal when Frasier's dad yells "He's got a gun!" at a banquet in Bulldog's honor, causing him to repeat his actions, whereupon he is berated by all the guests there. It turns out, however, that Frasier's dad doesn't really care about right and wrong in this case, he just wanted Frasier to shut up about it.

While there, what sounds like a gunshot is heard, and Joey jumps on top of Ross, apparently protecting him with his body.

When Chandler gets upset because Joey protected Ross instead of him, however, Joey admits he was actually protecting a sandwich.
  • Ralph Hinkley/Hanley from The Greatest American Hero was this up until the end of the series when his character was completely derailed and he became famous for being a super-hero. Earlier in the series, with rare exceptions, he avoided the hero role that was thrust upon him.

  • In Silent Hill, beating a god to death with a pipe tends to be an objective the player character achieves while pursuing a different goal, though how heroically that turns out for the characters depends on which of the Multiple Endings you get.
  • In the World of Mana series, being the chosen hero tends to happen by accident:
  • In Paladin's Quest, Chezni starts his journey because he was duped by his "friend" Duke, actually Zaygos, the Emperor of the Southern continent, into activating Dal Gren.
  • In Wario Land 3, Wario saves his own world and unknowingly breaks Rudy the Clown's curse on the music box world's inhabitants by defeating him purely in self-defence.

  • Megas XLR did this. Naturally, the beautiful anime-inspired (read "a complete parody of Sailor Moon") residents intended to put Jamie up against a powerful monster without letting him get in a word of objection edgewise. Or briefing him on what would kill off a monster, and what would merely appear to kill it, leaving it to come back stronger in a couple hours. Considering that the show's premise is "Giant Mecha lands in the yard of American Teenager, he uses it to save world (on drugs)", nobody should be surprised.
  • The Simpsons episode "Homer Defined" had Homer save the town from nuclear doom by using eeny-meeny-miney to find the right button. He is then lauded as a national hero. He later manages to recreate his blunder, but the townsfolk figure out he had no idea what he was doing, and his "reward" this time is inspiring the term "pulling a Homer".
    • Similarly, in "Little Big Girl" Bart accidentally puts out a fire when using fire extinguishers to propel himself forward along the road... his intention was just a cheap thrill, but the material from said fire extinguishers put out a fire that he encountered along the way.
    • The image is from "Moe Baby Blues", where Moe saves Maggie (who had been launched from the Simpsons' car in a traffic accident) just as he was about to jump off the Springfield Bridge.
    • Homer again in "Boy Scoutz in da Hood" when he and Bart go on a Father/Son camping trip with the Junior Campers. Homer is The Load all the way, losing their map and getting himself, Bart, and the Flanderses lost at sea. He only ends up saving the day when his keen sense of smell and the Krusty Burger map he brought along led them to food and rescue. It also turned out that the "correct" path led the campers who went down it to be attacked by mountain men, a bear, and eventually a psycho killer lurking in an abandoned campground.
  • In the South Park episode "Roger Ebert Should Lay Off the Fatty Foods", Cartman, furious that no-one saw him on TV, knocks over the mind controlling Planetarium projector in a fit of rage, inadvertently saving Stan and Kyle and wiping the mind of the Planetarium owner.
  • In an episode of Batman: The Animated Series, a very small-time thug, "Sid the Squid", working as a lookout somehow managed to accidentally "kill" Batman, which makes him a hero and a big-shot to Gotham City's underground. It also earned him Joker's wrath, however. Batman is actually still alive, however, and saves Sid and collars the Joker. Sid gets sent to a big prison outside of Gotham City limits, where he is still treated as a hero for almost killing Batman — and making both Rupert Thorne and the Joker look like fools.
  • This is the only reason anyone in Inspector Gadget accepts the title character as an Inspector. However, he's so clueless that he believes the hype and never realizes for himself that he's not really the hero. Then again, his bumbling often genuinely does help save the day, usually in a Spanner in the Works fashion.
  • Archie Comics: The superhero Bob Phantom created an identity in order to get close to superheroes and learn enough about them for his exposé book. In his first appearance, however, he is mistaken for a genuine superhero, and, worse still, ends up helping another hero save the day!

  • In Fragebogen, Ernst von Salomon relates that in the prison camp where the Americans interned him as a "security threat", he was informed that the general everyone was kowtowing to was the victor of Crailsheim. You never heard of the Battle of Crailsheim? It was the last German victory.
    In Crusade in Europe, Eisenhower noted that "...we occupied Crailsheim, but were forced to withdraw by unexpectedly strong resistance." The real story: the general, in his command tank, was cut off from his unit in the darkness. He finally found an armored column and traveled with it all night, before finding that it was an American column. He tried to slip off quietly (insofar as possible in a tank), but was spotted. So he opened fire with everything he had. The Americans heard firing, thought the Germans had outflanked them and were counterattacking from the rear, and pulled out of Crailshem. "Proving that a general without his command can be just as useful as a lance corporal."
  • In 1976, writer Roger Sharpe ended a thirty-four-year-ban on Pinball by demonstrating that it was a game that required skill, not luck.

Only later did Sharpe admit that his success was based on luck.
  • After the 2016 bombings in the Chelsea neighborhood of New York City, police were able to apprehend the suspect extremely quickly because two thieves who had been trying to steal the suitcase that one of the bombs was in accidentally defused it when they took it out of the suitcase and put it in a trash bag before making off with the suitcase. Because of that, police were able to access the info from the cell phone it was rigged to and track down the bombing suspect. Naturally, this made for late-night comedy fodder.
