Small Role, Big Impact

"It seemed that my lot in life was to either have big parts in small films or small parts in big films."
Bruce Campbell, If Chins Could Kill: Confessions of a B-Movie Actor

Small Role, Big Impact is when a minor character (an "Under-Five" line player, as they used to say) who, through his or her actions or words, has an impact on the story far, far beyond what such a minor character ought to have normally. Note the difference between this and a One-Scene Wonder, a character who has limited screen time but their actions or words have a huge impact on the audience.

This can occasionally overlap with One-Scene Wonder, One-Shot Character, Posthumous Character, The Ghost, Spear Carrier. Also see Plot-Triggering Death, where this person's end is beginning of the story. An Unknown Character takes this trope to its logical conclusion by not having them appear at all.

  • Choujin Sensen: Even though Haruna is no more than Love Interest of Tomobiki, it was her that encouraged Tomobiki to search up the [Superhuman Game] online and participate the death match (although Tomobiki didn't exactly expect that his life is on the line). You can say that she's the whole reason why Tomobiki starts to fight for his (somewhat pathetic) life.
  • Dragon Ball:
    • Grandpa Gohan is dead by the series' beginning and only appears in person during the Fortuneteller Baba Saga, but it was him finding Goku and raising him that turned Goku from the future destroyer of humanity to the altruistic All-Loving Hero we know and love.
    • Believe it or not, Raditz is essentially the catalyst for the entire second half of the Dragon Ball manga. Had Raditz not remembered his little brother and come to Earth, the entire series would have been turned on its head: Piccolo and Goku would never have teamed up and thus Piccolo wouldn't have joined the Z-Fighters. He may have even remained evil, and continued on with a plan to terrorize planet Earth, had he and Goku not joined forces. Goku wouldn't have trained with King Kai, but merely at his own pace, and would have been far too weak to combat the androids by the time they arrived, assuming he hadn't already died from the heart virus he was to contract. Gohan would never been trained by Piccolo, and thus would never have become a fighter at all. Vegeta and Nappa would never have received the transmission involving the Dragon Balls, and thus would never have visited the Earth, thus remaining under Freeza's thumb — Freeza himself would also never have been killed, allowing the Cold family to continue terrorizing the universe. And who knows what trouble Babidi would've cause if he'd arrived earlier and unleashed Buu unchallenged. Despite being the weakest villain at the start of the series, Raditz coming to Earth is what allowed the Z series to be what it became.
    • Dr. Gero. He's long dead in Trunks' timeline and is only around for a few episodes as Android 20 before being killed by Android 17. However, it is Gero who created all the androids, including Cell, and his actions turns two timelines into a living hell and nearly destroys the solar system of the main timeline. Literally everything bad that happens in the Android/Cell Saga is his fault.
    • Van Zant, the Ax-Crazy gunman who shot Mr. Satan and Bee, triggers the latter half of the Buu Saga. He only appears in two episodes, but his attack on Mr. Satan and Bee, whom Majin Buu had befriended, directly results in the creation of Evil Buu.
    • As of Dragon Ball Minus, Bardock and Gine. They were the ones to send Goku to Earth. If they hadn't, Goku would have died along with their planet.
  • Elfen Lied:
    • Tomoo appears in one episode and one manga chapter, but it was his actions that ultimately played the biggest role in turning Lucy into a bitter figure who hated humanity (namely he beat her puppy to death with a rock/vase and made Lucy watch when he did). Lucy snapped and brutally executed him and his cronies, as well as someone who may or may not have meant to betray her. It was all downhill from there.
    • Aiko Takada has an equally brief appearance, but she's Lucy's second human friend, and it was her death that resulted in Lucy being captured and imprisoned in the Diclonius Research Institute, as well as the catalyst for Lucy's long-running vendetta with Kurama.
  • Lord Asano is never actually seen in Princess Mononoke, but those are his samurai who are dangerously close to conquering Iron Town, and it may also have been his men that Ashitaka saw brutalizing the countryside before.
  • Admiral Robert J. Hanner, United Planets Space Force (ret.), from Irresponsible Captain Tylor appears only about four times in the 26 episode series, and only once in a speaking role. However, directly or indirectly, he's responsible for Tylor becoming a starship captain, the Soyokaze crew getting demoted, the war with the Raalgon being able to conclude without additional bloodshed, and his death sparks a Heroic BSOD from Tylor.
  • Dying Breed rarely appear in BECK, but they inspire both Ryuusuke and Koyuki to push the band to great heights, and Eddie Lee's death causes a Heroic BSOD from almost the entire music world. Not only that, but rumors of an unreleased song of theirs drive a huge portion of the plot.
  • Rin in Naruto. Her death caused a major villain's Start of Darkness, and by extension nearly every significant event in the plot.
    • Sasuke in The Last. He may have been Demoted to Extra, but if he hadn't arrived in Konoha when he did with Hiashi in tow, then the Hokage Monument would have been reduced to dust, Kakashi and countless others would have been killed and the Raikage would have blown up the moon, killing Naruto and co.
  • Grisha Jaeger of Attack on Titan. No one has seen hide nor hair of him since very early in the series. Even so, it's heavily implied he knows many mysteries about the Titans, and is the one who gave Eren his Titan Shifting powers, via a mysterious injection.
  • Revolutionary Girl Utena has an example in Mrs. Ohtori, the mother of Akio's fiance Kanae and the wife to the actual chairman of the board at Ohtori Academy. She has less than a minute of screen time but every single thing about her ties into all the overall themes of the series. There's even a website which analyzes the symbolism within her first and only appearance, called Mother Dearest.
  • The Number Due from Magical Girl Lyrical Nanoha StrikerS. Despite being the most minor of the twelve Numbers, she's responsible how the Big Bad Jail Scaglietti got Olivie Sägebrecht's DNA and could create the Sankt Kaiser's clone Vivio Takamachi, who is the Vessel of the Saint's Cradle and the main character of ViVid. Due was Quattro's mentor, the most vicious of Scaglietti's three Co-Dragons, who inherited many traits of Due's psyche and personal ambitions as a result of the time that they spent together. She also provides Bad Guys Do the Dirty Work by killing the TSAB High Council and Regius Gaiz, which goes a long way towards making sure the Bureau doesn't repeat their mistakes.
  • Hibari and Hikari from Mawaru-Penguindrum. For a long time, their only appearance was in the ending credits, and then they showed up briefly in a backstory episode to give some insight into Himari. However, they end up being absolutely integral to the ending when they show up for less than five minutes in the final episode to drop off their new album, which holds Himari's favourite phrase and the fate-transfer spell that allows her to live.
  • Leaky-Eye Luka in Part 5 of Jojos Bizarre Adventure. He only appears for one chapter, has no stand ability, and pretty much defeats himself, but his death is what causes Buccellati to track down Giorno, resulting in the plot between the two of them to take over and reform Passione that drives the rest of the storyline.
    • Similarly in Part 5, Polpo appears in only two scenes (his own stand has more page-time than him,) but his death drives the plot just as much as Luka's, both in the revelation that he had a massive treasure hoard hidden away (that Buccelati uses to boost themselves to Operator status) and the revelation that he was responsible for keeping safe Trisha, the daughter of The Don of Passione, and now that he's dead the responsibility is passed on to Buccellati.
    • A petty thief named Dario Brando abused his only son and treated him like crap. Because of this, the son became the Tyrant who would menace the Joestar/Kujo clan and their allies for over a century.
    • Gray Fly is the Starter Villain of part 3, and he is never mentioned after his defeat. However, were it not for him, the epic quest across multiple countries that makes up the bulk of the story would have been reduced to a mere plane flight and ended in a few days.
  • Kagerou Project: Tsukihiko, Azami's husband, appears very briefly in the anime, and in only one of the music PVs, yet his love and acceptance of Azami was what lead her to develop her own emotions, resulting in the creation of the Heat Haze World and the Favouring Eyes Snake, born of her love for her husband and child, and the snake that is the key to saving everyone. Azami herself could count, as she is the source of the main cast's powers, and she appears nearly as little as her husband does.
  • Gene in Mobile Suit Gundam. He's a random Zeon red shirt killed in the first episode, but his decision to disobey orders and attack the Project V mobile suits is what causes Amuro to hijack the Gundam and consequently set off much of the UC in motion.
  • InuYasha:
    • The demon necromancer Urasue is only around for two episodes, but she has quite the impact on the series, having been the one to resurrect Kikyo.
    • The moth demon bandit Gatenmaru only appears in two episodes as well, but he forces Inuyasha into his Superpowered Evil Side, resulting in his death and the deaths of quite a few of his human minions; it's this incident that finally convinces Inuyasha to give up his plan of using the Shikon Jewel to become a full-fledged demon.
  • Obviously Kaworu from Neon Genesis Evangelion, who serves major relevance as both the final angel and having some of the most poignant scenes in the entire series.

    Comic Books 
  • Arms dealer Abe Rothstein in 100 Bullets. He appears in precisely one issue of a 100-issue series (issue #89), and he's killed at the end of that issue. In said issue, though, we learn that he was the source of Agent Graves' attachés all along. His death signals the end of Graves' "game" with the leaders of the Trust.
  • Martian Manhunter villain Commander Blanx appeared in a grand total of two JLA stories. In the first of those stories, however, he engineered the destruction of the entire Martian race, transforming J'onn J'onnz from the jovial crime fighter he was in the Silver Age and into the introspective loner he is today.
  • The Green Goblin in The Pulse. He's only in a few issues, but it was his final unmasking.
  • Xiao Meng like most of the Handicapped Warriors/Crippled Legion in The Ravages of Time has a small role relative to the canon cast, the major chain of events in Ravages begins with Xiao Meng sacrificing himself (non-fatally) during a mission: The group's leader Liaoyuan Huo was so distraught by this as to leave the Handicapped Warriors and go freelance, with one of his contracts being an assassination attempt against Cao Caonote , the thwarting of which was immediately followed by a retaliatory purge of the Sima clannote , spurring both Sima Yi's revenge-motivated political ambition and Xiao Meng's participation in Lu Bu's war with Cao Caonote , the former of which coalesced into Sima Yi's long-term plan and the latter of which culminates in one final assassination attempt against Cao Cao, the failure of which endangered Sima Yi's climb to the top so he sold out Xiao Meng to lynching... which both led to Huo's wrecking Yuan Tan's army while searching for Meng's corpsenote , permanently damaging Tan's standing in the Yuan clannote , and to the split between Huo and Yi that led to Huo permanently taking up his cover identity: Zhao Yun.
    • Assuming that the dream that opens the first chapter and is referenced multiple times after is actually the canon ending of Ravages, then the chain of events begun with Xiao Meng's self-sacrifice ends with Zhao Yun killing Sima Yi over fifty years after Meng's death.

    Fan Fiction 
  • In a Digimon fan fiction Zero 2 A Revision Skullsatamon is introduced as one of Demon's most trusted Black Generals whom request Demon that he head out and have some fun with the Digidestined. Even though he ends up getting killed after his brief appearances by Shaun (Just like how he is the first to be killed by Imperialdramon Fighter Mode), his influence in the plot is tremendous. He is the one who kills Blackwargreymon which results in Davis unlocking his own Holy Armor of Miracles, when he tries to take down Tai and Sora along with him, Shaun on instinct calls them as his parents before striking Skullsatamon down which forces Shaun to reveal his true origins. In the mean time, Umbradevimon, previously unsure of which Digidestined to corrupt, decides to corrupt Davis Motomiya after watching the fight. Finally Demon forgot to close his portal used to teleport Skullsatamon which gives Demon a chance to completely corrupt a currently soulless Darkheart into a sadistic being using his own Dark Spores.
  • A few characters in Angel of the Bat appear to be this, but have actually had large roles, just off-camera. (Deacon Blackfire only appears in a flashback but did a lot to create the Big Bad The Seraphim, Joshua Lebowitz only has a few scenes but has spent years in defiance for The Seraphim etc.). But Jason Todd/ Red Hood's role in the story is simply acting as a hired killer for a few scenes. Despite this, defeating him helps bring closure to Stephanie's story arc and his knowledge of infiltrating The Seraphim's base is what leads to one of the two climaxes.
  • In Final Fantasy VII fanfic The Fifth Act, Yuffie is only present for a few scenes and is only there as the Plucky Comic Relief. But she makes a huge impact as Cloud rescuing her gets him an audience with the Emperor of Wutai, her father. Her habit of stealing materia saves her father's life and forces Cloud to work a diplomatic solution when assassinating her father for his Honor Before Reason stubborness was not a option. Cloud manages to convince Lord Kisaragi to surrender to Shin-Ra on his own terms which in turn attracts further attention from Shin-Ra. Further attention from Shin-Ra gets him recruited into the company in turn turn has major consequences in the latter half of the story.
    • Young Cloud is only present for two chapters but he's privotal in getting the elder Cloud's cover to fall part and his rescue of Kunsel tells the rest of the cast where Cloud is being held.
    • Vincent has very few scenes but he turns the Turks against Hojo and is the one who kills him.

    Films — Animated 
  • The Little Green Aliens in Toy Story 3, upon rescuing the toys from the incinerator.
  • Edna Mode from The Incredibles. She appears three times, all in the first half of the film. She's the one who alerts Helen to her husband's moonlighting hero work, and convinces Helen to go track Bob down.
    • From the same film, Bomb Voyage. He's the one who throws the bomb onto Buddy, which causes the train crash, which helps lead to the Super Registration Act, and is part of Buddy's impetus for turning into Syndrome.
  • Ellie in Up, whose death is responsible for Carl's attitude for most of the film, and the real estate agents who drive Carl to fly his house to South America.
  • "Frightening" Frank McCay in Monsters University only shows up in the beginning of the film but he is the one who encouraged Mike to become a scarer in the first place, thus setting off the plot of this film and the next one.

    Films — Live Action 
  • Apollonia in The Godfather was barely seen despite being Michael's wife back in Italy. Her death at the hands of a car bomb meant for Michael drove him to become the Corleone's head Don for the entire trilogy.
  • Babe: Pig in the City has Snoop the airport sniffer dog. He only appears briefly, but in his limited screen time when demonstrating how he does his job at the airport, he unintentionally misinforms the airport security that Esme and Babe are carrying illegal substances and gets them temporarily arrested. This causes them to miss their connecting flight and the whole plot of the movie kicks off from here.
  • The Blind Seer in O Brother, Where Art Thou? is only in the movie for a couple of minutes or so at the beginning of the film, and for less than a minute at the very end, but his initial scene sets up the adventures of the main characters.
  • In the 1999 movie version of A Midsummer Night's Dream, Hippolyta (the vanquished Amazonian Queen marrying Duke Theseus) is mostly a background figure. However, in the movie when the Duke and his party discover the lovers in the morning, Hippolyta pulls Theseus aside and has some words with him, which go unheard by both the audience and other characters. Afterward Theseus announces that the lovers may marry according to their own wishes, rather than according to the decree of their families.
  • Ricardo Montalban once said that he almost passed on coming back for Star Trek II because, as it is written in the script, Khan is actually only onscreen for about fifteen total minutes over the course of the entire movie, and his actual spoken dialogue is pretty minimal as well when compared to the main characters. But then he realized, as he read the story, that Khan's impact on the other characters is present on every single page of the script, and immediately agreed to reprise the role. (It's worth noting that Khan's name hadn't been put in the title yet.)
  • In The Third Man, the chillingly evil Harry Lime is at the center of the plot but appears for less than 10 minutes on screen. Orson Welles plays him as just a normal guy you wouldn't look twice at, and takes three seconds in a search-light and a somewhat sheepish 'you caught me' grin to completely upstage Joseph Cotten's excellent performance and steal the film.
  • Jack Palance had a film career of 50 years and over 70 movies, but when he died in 2006, one film role consistently stood out in all the obituaries and tributes dedicated to him: the role of the taunting, smiling hired gun Jack Wilson in Shane. Palance's Wilson is widely regarded as the definitive Western bad guy. Total screen time: eight minutes. Total words spoken by Wilson: less than fifty, but he makes the most out of two of them: "Prove it."
  • Sarah Paulson's single scene in Serenity sets up the whole third act of the film.
    • As an interesting bit of trivia, for this reason Joss Whedon cut down the role of the Operative as Mr Exposition, because he thought it was just far, far scarier for him to to be the Implacable Man, and he isn't being implacable when making speeches about Mal as the worthy adversary.
  • Everything that transpires in the original Star Wars trilogy can be attributed to the actions of the gunner on the Star Destroyer at the beginning of A New Hope who decides not to shoot the pod that C-3PO and R2-D2 are in.
  • In Top Gun, It's because of Cougar's Heroic BSOD in the beginning that Maverick and Goose get to go to Top Gun.
  • The Emperor in Onmyoji is hardly in it bar a couple of scenes in which he does very little that's useful, but it's his rejection of Sukehime that leads to most of the villain's attempts to kill the imperial family via her angry father and her eventual transformation into a demon.
  • Mink in Millers Crossing only has two short scenes (one of those over the phone), and dies less than halfway in, and yet his "relationship" with both Bernie and Eddie Dane sets off a large part of the plot.
  • Dom Deluise as Bernie the agent in The Muppet Movie gets only a few minutes near the start of the film, but kicks off the plot by convincing Kermit to go to Hollywood and get into showbiz.
  • Even though everyone pictures Donald Pleasence as Ernst Stavro Blofeld, he only plays him in one film, You Only Live Twice, and even then his face is only revealed for less than a half-hour.
  • The Wicked Witch of the West appears onscreen for only about nine minutes of the 101-minute runtime of The Wizard of Oz (with Margaret Hamilton's other character, Miss Gulch, appearing for about three minutes). And yet she is without question the character in the film who has had the greatest impact on popular culture, being remembered as one of the most frightening villains in movie history, and is the Trope Codifier for the Wicked Witch. Both Wicked and Oz: The Great and Powerful are plainly inspired by her portrayal.
  • In The Bourne Identity, Clive Owen has only 3 minutes of screentime as "The Professor", and he never talks until his final scene, almost a half-hour from the end, in which he delivers the series' Arc Words "Look at us. Look at what they make you give."
  • WarGames: The missile crewmen played by John Spencer and Michael Madsen in the beginning. It is due to their disagreement during the opening simulation that NORAD decides to replace the missile crews with the WOPR system.
  • The plot of The Gods Must Be Crazy gets underway when an airplane pilot, who never speaks and whose name we never learn, finishes drinking from a Coca-Cola bottle and then throws it out the window, down to the Kalahari Desert below. When the bottle is discovered by a tribe of Bushmen, it triggers a social revolution that results in violence breaking out in Bushman society for the first time, prompting the protagonist to save his village by taking the bottle hundreds of miles across the desert and throwing it into the Atlantic Ocean. Along the way, he encounters white people - and black people too, for that matter, since the Bushmen are technically of a different African racial stock - for the first time, gets his first glimpse of 20th-century Western society, and almost single-handedly captures a band of revolutionary terrorists who had already come close to overthrowing the government of Angola.
  • In Big Daddy, the character of Kevin Gerrity (Jon Stewart) is onscreen for only 20 minutes at the most - less than a quarter of the movie's running time - yet the crux of the film's plot hinges on the protagonist being mistaken for him, a mistake that Gerrity himself can't clear up because he's out of the country for most of the story. He then shows up unexpectedly during the climax and resolves the plot for a happy ending at literally the last possible second.
  • Most of the 1963 Disney film Summer Magic takes place in and around a little country house in Maine sometime before World War I. The house is being leased by the absentee landlord Tom Hamilton, who, despite being at the very least the third-most powerful person in the town, does not appear until less than 30 minutes before the movie ends - and even when he does, it takes a scene or two for him to actually be identified by name.
  • A very young Rita Moreno appears in Singin' in the Rain as Zelda Zanders exactly four times, the first three with no lines; once as part of the red carpet procession of stars at the premiere of "The Royal Rascal" (accompanied by "J. Cumberland Spendrill III, that well-known eligible bachelor"); once dancing at the after party with some other rich old guy; once watching the "Beautiful Girl" sequence; and once when she sets the climax in motion, leading Lina to the sound studio where Don and Kathy are celebrating the last dub of Lina's lines with a long, passionate kiss.
  • The titular Beetlejuice is considered one of Keaton's greatest performances, and the character is still so iconic that he gets referenced often in popular culture nearly 30 years later. Also, he's on-screen less than eighteen minutes.
  • Anthony Hopkins' first appearance as Hannibal Lecter in Silence of the Lambs last for roughly fifteen minutes. It is an iconic villain role that made him famous and spawned a sequel and a prequel with the actor.
  • Samuel L. Jackson's role as Nick Fury is one of the more famous roles in the Marvel Cinematic Universe as he has appeared in many of the movies and in a few episodes of Agents of S.H.I.E.L.D.. Despite this, he is usually a One-Scene Wonder, appearing in a single scene, some of which, are The Stinger for those films. He likely only has about one hour of screentime spread out throughout the first two phases of the franchise.
  • Despite being one of the title characters of Captain America: The Winter Soldier, the Winter Soldier himself does not appear in as many scenes as one would think and has barely any dialogue. Despite this, his presence and the emotional impact that he has on Steve (both of his personas) can be felt through the entire film.
  • Back to the Future: The "Clock Tower" lady who interrupted Marty and Jennifer's kiss to tell them how lightning struck the Hill Valley clock tower in 1955, giving him a flyer with the exact date and time it happened. If not for her, Marty would have been stuck in 1955, reaching 1985 again only by the natural passage of time.
  • The Navy SEALs in Zero Dark Thirty don't appear until the last 20-30 remaining minutes, yet they are the ones who finally raid Bin Laden's compound. The SEAL who kills the very man barely has any dialogue, has little screen time and isn't as prominent as his team members.
    • There is also Debbie, a young analyst and admirer to Maya's work, who gives the information that Abu Ahmed may have faked his death because his deceased brother looked like him, prompting the CIA to track him and lead to his home: Bin Laden's compound.
  • Matthew McConaughey's Mark Hanna from The Wolf of Wall Street only appears in the first half of the film, yet he is one of the main influences to Jordan Belfort to be a ruthless broker and a substance abuser.
  • The plot of Saving Private Ryan is kicked off by one woman typing up condolence letters in an office. Through sheer coincidence, she types up the three brothers' letters at once and brings it to the attention of her superior. She has no lines and does not appear past this scene, yet this is what inspires the government to arrange for the fourth brother to be brought home.

  • Watson's friend Stamford has about two lines, doesn't make it past the first chapter of A Study in Scarlet, and is promptly never seen again. But he introduced John Watson and Sherlock Holmes to each other, resulting in their forming a life-long friendship, and kicking off one of the most well-known and enjoyable mystery series of modern literature.
  • In A Song of Ice and Fire, Balon Greyjoy is one of the eponymous monarchs in the War of Five Kings. He barely has any time interacting with the POV characters, and appears in only small parts of two chapters in the second book, and doesn't reappear before dying off screen in the third. However his decision in the second book to go to war with the North rather than joining them effectively ends the chances of that king to win their war.
    • Mirri Maz Duur only appeared in four chapters (three episodes) of A Game of Thrones, including the one where she is killed. The only POV character she interacts with is Daenerys. However, her actions become not only the driving force behind much of Daenerys's story arc, but also the reason that dragons (and in turn, stronger magic), have returned to the world. (Given that said dragons are expected to defend the Wall against the Others, Mirri Maz Duur might end up having a greater hand in saving Westeros than anyone besides Daenerys.)
    • Lord Walder Frey appears in only three chapters of the series (or episodes of the show). He is still able to orchestrate a Wham Episode in which he helps win the war for his side by killing off several important characters.
    • Lysa Arryn has very little pagetime, but while Saying Too Much in her last chapter she reveals that she is directly responsible for the events that lead to the War of the Five Kings (murdering Jon Arryn, causing Robert to ask Ned to be his Hand; implying the Lannisters as his murderer to Catelyn causing her to eventually take Tyrion captive and anger Tywin Lannister).
  • Hannibal Lecter from The Silence of the Lambs. He's a minor character in the novel (and in the film he's on screen for only fifteen minutes or so), and yet he drives the plot forward on several occasions all by himself. (Amusingly, Anthony Hopkins set a record by winning the Best Actor Oscar in the shortest amount of screen time.)
    • This is even more the case in the preceeding novel, Red Dragon. Unlike his relationship with Clarice, which formed the real meat of Silence of the Lambs, his relationship with Will Graham is mostly restricted to a mutual hatred. He appears on a total of seven pages, and new scenes had to be written for him in the Edward Norton adaptation to justify his billing. His actions continue impact the story long after his final appearance, however.
  • Lily Evans really isn't in much of Harry Potter, but her actions drove the entire characterization of Snape, and her Heroic Sacrifice set up the entire plot.
    • The eponymous Goblet of Fire only gets a couple appearances early on the book and then is (almost) never mentioned again. It, however, kickstarts the book's main plot.
    • Narcissa Malfoy in the latter Harry Potter books. In terms of facetime and notoriety, she takes backseat to her husband and son and mostly just another snobby wizard supremacist. However, in the sixth book, her binding Snape to the Unbreakable vow is ultimately responsible for the climax of the story. And in book 7, her willingness to lie to Voldemort about Harry's death is what gives Harry the chance to win the war once and for all.
    • Kreacher. When screenwriter Michael Goldenberg tried to adapt him out, J. K. Rowling told him that doing so would put a Spanner in the Works of the seventh film. (Goldenberg can be forgiven for attempting it, since Kreacher's one plot-critical moment had, at the time, not yet been published.)
  • Sasha in Warriors: The New Prophecy. Although she only appears once or twice, she mothered the villain's children, who go on to become super important characters.
  • The Maltese Falcon: General Kemidov is The Ghost, but even before the story begins, when Gutman wanted to buy the McGuffin, he realized that it would be important and replaced it with a Mock Guffin that the gang found very easy to steal, making him the real Magnificent Bastard of the story.
  • The Lord of the Rings books are full of this. You have characters like Erkenbrand, a Marshall of Rohan leading the troops that Gandalf collects to save everyone at Helm's Deep, or Ghan-buri-Ghan, a Noble Savage tribesman who leads the Rohirrim around an ambush so they can arrive at the Battle of the Pelennor Fields in time and at full strength. And, all puns aside, let's not forget that three of the shortest and least competent characters are the ones who won the war—Frodo, Sam and Gollum.
  • Also occurs in The Hobbit with characters like Bard, and elsewhere as well — Tolkien was obviously very fond of the idea that everyone, not just the protagonists or the most powerful beings, can have a major influence on the world.
  • Arianna Ortega in The Dresden Files interacts only with Harry, and appears in a grand total of three chapters before biting it. Her plans result in Harry damning his soul forever, and sets the plots for book 12 and 13 in motion.
    • The minor Red Court Vampire "Bianca St. Claire" only appears in Books 1 & 3. However her falling out and subsequent attempts at petty revenge against Harry both start off the war with the White Council and eventually gives Harry the opportunity to wipe out her entire species. Whoops?
    • He Who Walks Behind. He is a powerful demon knight on the levels of being a Physical God. As of book 14 Cold Days, he was only in a single chapter flashback in book 13 Ghost Story. Besides that, he was referenced maybe five times in the entire series. But his actions in Harry's past, the brutal murder of a gas station attendant Harry tried robbing drove him to avenge the little guy and develop the Chronic Hero Syndrome that would make Harry face down forces that no mortal had tried challenging before.
  • The Story Within a Story in Hans Brinker, or The Silver Skates about a boy plugging a dike with his finger and preventing a flood is more famous than the actual story of Hans Brinker and his skates.
  • Clarisse McClellan from Fahrenheit 451 is obscurely written out of the story very early on; however, her influence on Guy Montag instigates the entire plot and every event that happens therein. (Some adaptations even write her back in later.)
  • In the present-day The Wheel of Time, Aginor is one of the least appearing, least accomplished members of the Forsaken ( he dies twice without accomplishing much that's noteworthy). In the backstory, on the other hand, he created the Shadowspawn races, meaning he was responsible for most of the mooks the heroes fight and for untold suffering caused by his "children" over the millennia.
  • In the Fear Street spin-off series Fear Street Seniors, the first actual senior to die was Danielle Cortez. She only appears in a few pages and doesn't even receive the courtesy of a yearbook entry until the sixth volume, which is three books after her death, but the fact remains that she dies on the very first day of the new school year, which sets the mood for the rest of the school year. Her death is the harbinger for the rest of the seniors who die throughout the year.
  • Professor James Moriarty is only in two works in the entire Sherlock Holmes canon (the short story "The Final Problem" and the novel The Valley Of Fear), and he is almost entirely behind the scenes in both, with no dialogue in either work, and no explicit appearances aside from one brief scene where Holmes points him out to Watson on a train. Nevertheless, he is the only character in the canon who Holmes ever called his intellectual equal, and he was the catalyst behind Holmes' infamous three-year disappearance—which was originally meant to be his death. For good reason, many adaptations significantly increase his presence, making his role as Holmes' archenemy much more explicit.
  • The ghost of James Incandenza in Infinite Jest doesn't even have any lines, but single-handedly sets almost the whole novel's plot into motion which culminates in the apocalypse.

  • In Lost, Jacob never appeared onscreen until the end of the fifth season... in an episode in which he was killed at the end. In the next season he appeared just a handful of times as a ghost or in flashbacks. Nevertheless, he is one of the major characters in the Myth Arc of the series.
  • Even people who haven't seen 24 are likely aware of the cultural phenomenon that is Mandy (aka "Naked Mandy"), the cold, ruthless Chess Master assassin who routinely evaded capture only to make a sudden, shocking, bombastic return when the heroes least expected her. Fans of the show, however, know that she only ever appeared in seven episodes, almost never for more than one scene, and she only ever made two "shocking returns" (and it was never a surprise for any of the heroes - none of them met her or knew who she was until her last arc in Season 4 - only for the audience). Still, she did make quite a splash whenever she did show up, most notably in the Season 2 finale, where in her one minute of screentime she managed to single-handedly turn the upbeat, triumphant ending into a horribly uncertain Downer Ending.
  • In the opening scene of Orphan Black, Sarah Manning sees a woman who looks exactly like her, Beth Childs, at a train station. Then Beth throws herself in front of a train and Sarah steals her identity, kicking off a series of events that soon leads to the revelation that they are clones, the whole premise of the show. Although Sarah spends most of the first season pretending to be Beth, she has only properly appeared since the opening scene in a video and a brief dream sequence. Her death plays a major role in the arcs of Paul Dierden and Art Bell, and her presence is very much felt even well into the third season.
  • Judah Botwin is dead before Weeds even begins, and he only appears twice, briefly, in video footage taken before his death. However, it quickly becomes clear that he had a very stabilizing influence on his family, who almost immediately begin acting out once he's gone. His wife, with no idea how to provide for the family in his absence, turns to dealing marijuana, and his sons begin exhibiting sociopathic behavior, particularly Shane, for whom Judah was one of the only people who truly understood him and encouraged him to be himself, and area in which his mother is clearly out of her depth.
  • Phil Davis appeared on Merlin in a guest spot that lasts no more than five minutes. In that time he mortally wounds King Uther, a major character who had been on the show since the beginning, and changes the entire course of the show.
  • Doctor Who:
    • Harriet Jones, Prime Minister (yes, we know who she is), played by Penelope Wilton, appears in a grand total of four episodes. In the third of those, the Doctor's reaction to something she does changes the entire course of history and has serious consequences for the next three seasons of that show and all of Torchwood. Then, despite having been thoroughly screwed over by said Doctor, she proceeds to help save the world with a tear-jerking Heroic Sacrifice. She's also a Four-episode Wonder, as she's one of the most iconic supporting characters of the new series and a fan favourite.
    • Cass, in the "Night of the Doctor" minisode. She appears in Doctor Who for all of six minutes, most of which is after her death. But her death is what pushes the Doctor over the Despair Event Horizon and into participating in the Time War, which had a HUGE impact on the rest of the series.
  • From Hannibal, we have Garrett Jacob Hobbes, the serial killer known as the Minnesota Shrike. He appears as the primary antagonist of the first episode, and his crime spree is stopped by the end of the episode when he is shot to death by protagonist Will Graham. However, the guilt Will feels over killing Hobbes, combined with the guilt Hobbes' daughter Abigail feels for having an indirect hand in her father's murders, contributes a great deal to both Will and Abigail's storylines in Season One. The incident also sets up the Arc Symbol of the raven-feathered stag, and foreshadows the climax of Season Two.
  • Jessie Taylor (Angel Coulby of Merlin) in Dancing on the Edge, whose role is to sing and get murdered, but remains one of the most memorable aspects of the miniseries.
  • Once Upon a Time:
    • Zelena's birth father appears in only one episode, simply as a palace gardener disguising as a prince. He seduces Cora and gets her pregnant, but does not appear again except asking for a bribe. Because of the illegitimate pregnancy, Cora abandons Zelena in the forest - which leads to her getting taken to Oz and becoming the Wicked Witch of the West.
    • Dorothy Gale likewise only appears in one episode. All she does is arrive from Kansas and mistakenly throw the water on Zelena. However she acts as a Face Heel Door Slam and Zelena turns down her redemption and sets out on her path to villainy.
    • The Duke of Weselton courts Princess Helga and then makes a pass at her older sister Ingrid. In trying to save her sister from an attack, Ingrid accidentally kills Helga and is sealed in an urn by her other sister Gerda.
  • Band of Brothers shows Moose Heyliger being shot in a case of Unfriendly Fire by an unnamed sentry. The man in real life was quickly transferred to another regiment for his own safety and does not appear in the series again. Nonetheless this results in the incompetent Norman Dike being put in charge of Easy Company through the Battle of the Bulge. Many men lost their lives (or limbs) due to the man's poor leadership skills.
  • John Colicos played Kor, the first ever Klingon, only once on Star Trek: The Original Series before reprising the role decades later on Star Trek: Deep Space Nine, yet his Genghis Khan-influenced performance set the standard for all Klingons throughout the whole franchise.
  • Breaking Bad: Combo was killed mid-way through season 2 after only a few lines, but his death caused Jesse and Walt to hire Saul as their lawyer, which had a huge impact on the plot - among other things, Saul was the one to hook them up with Gus. And then he affects the plot again in season 3 when Jesse meets someone related to the kid who killed him.
    • Brock Cantillo. He may be a little kid with very few appearances, but when Jesse found out Walter poisoned him back in Season 4, he permanently cuts ties with Walter and becomes a significant threat.
    • Dr. Delcavoli. He's only used as exposition for Walt's cancer, barely being seen for the first two seasons. However, his treatment helped Walt's cancer enter remission; it may have altered Walt's attempts to break bad in the meth business since he assumed that he would die and leave his family a sizable amount of cash before going in too deep.
  • In How I Met Your Mother, the Mother's First Love Max isn't even seen on-screen but his death was enough for the Mother to swear off dating and be unable to move on in any relationship.
  • Before Batman the Riddler had all of two appearances in the comics, neither in over a decade. Frank Gorshin's performance single-handedly saved the character from obscurity, the Riddler himself is considered a core villain in Batman lore, with most adaptations drawing heavily on Gorshin's version of the character.
  • In Gotham, Jerome only shows up in a few episodes, dies in the third episode of Season Two, and also causes enough chaos that watching a video recording of his antics causes people across Gotham to snap, thus making Jerome, in all likelihood, the inspiration for a certain clown.

  • Joe in Show Boat. It helps that he has one of the best Broadway songs ever written, "Ol' Man River."
  • It's easy to forget that Tybalt from Romeo and Juliet is only in about 3 scenes in the play. But as Isaac Asimov pointed out succinctly in his analysis of the play, without Tybalt, the rest of the play's events would never have happened.
    • Remember that there was more than one friar? Of course not, because Friar John is in one scene and has about five lines. But because he fails to deliver a letter to Romeo, the tragedy of the climax is allowed to unfold.
  • Jessica, daughter to Shylock in The Merchant of Venice, has very few lines, but the whole play hinges on her elopement and her conversion to Christianity, which drive her dad over the edge. Whether she's seen as a "good" or "bad" character is a key decision when staging the play, and directors tend to give her plenty of extra stage time to pray in Hebrew or look tragic. Lorenzo could also be seen this way—besides being the boy who steals Jessica, he has one of the play's best soliloquies ("How sweet the moonlight sleeps upon this bank...")
  • In The Magic Flute, the Queen of the Night only appears in three scenes, which include both of her extravagant coloratura arias.
  • In The Winter's Tale, Antigonus was supposed to kill a small baby, but, unable to do so, he left it in the wilderness instead (mostly because he was eaten by a bear before he could do anything else). That baby ends up being the hero of the story.
  • During "At the End of the Day," a song in Les Misérables, a nameless factory worker snatches a letter from Fantine for no particular reason and reads it aloud to taunt her. The letter reveals that Fantine has an illegitimate daughter, which in turn gets her fired, which in turn forces her into prostitution, which in turn prompts Valjean to pity her, which in turn makes him on the scene to save a man from a runaway cart, which in turn makes Inspector Javert reveal that a man he thinks is Valjean has been arrested, which in turn makes Valjean decide to turn himself in and promise to care for the dying Fantine's daughter, which in know what, it's probably easier to simply say that the Nameless Factory Worker is the most important character in the show.
  • The titular character in The Phantom of the Opera thoroughly dominates the musical - and yet is only onstage for 30-40 minutes of a two and a half hour production.
    • Also, Joseph Buquet really doesn't do much while he's alive besides loom about the place, tell the corps de ballet scary stories about the Phantom and set up the Chekhov's Gun of the Punjab lasso - but his shocking death is the final nail in the coffin of Christine deciding the Phantom is bad news and choosing Raoul; all (further) hell breaks loose from there.

    Video Games 
  • Bane in Batman: Arkham Asylum. His only appearance is a brief, yet epic confrontation, but his Venom serum is the catalyst for the game's plot.
    • The same could be said for the Electrocutioner in Batman: Arkham Origins. The fight with him ends with you hitting him and him hitting the ground, and then he's unceremoniously killed off by the Joker, but the weapons you get from him, the Shock Gloves, have a heavy impact on the rest of the game. Not only are the Shock Gloves just that awesome, but they also allow Batman to save Alfred's life, as well as enable him to get around the Joker's Sadistic Choice by Taking A Third Option.
  • The "Oriental Gentleman" from Grand Theft Auto III, an unnamed man who just so happens to be a prisoner in the same police convoy the player character is in - the fact that the game consists of typical Grand Theft Auto fare rather than the player being behind bars for the whole game (or at least a few minutes, considering the series) is because the Colombian Cartel decided to hold up the convoy and take this one prisoner.
  • High Templar Karass of Starcraft II fame. He and his men meet up with Zeratul, help him fight through the zerg, and then he and his remaining troops pull a Last Stand Heroic Sacrifice to allow Zeratul to escape. Yet those few minutes, he and his men might have saved the universe.
  • Grand Marshall Garithos from Warcraft III posthumously became this once certain events in World of Warcraft transpired. His fantastic racism was one of the key factors that drove the Blood Elves from the Alliance, causing a small number of them to join will Anti-Villain Illidan Stormrage, and the rest to eventually side with the Horde. To a much lesser extent, he helped Sylvannas Windrunner retake the capital of Lordaeron, which led to it being taken by the Forsaken, though in this case Sylvannas actually promised to hand the city over to him and betrayed him when she was done using him.
  • In MOTHER 3, Hinawa, Lucas and Claus' mother, is only seen in the prologue of the game then dies offscreen during Chapter 1. Even so, she has a big impact in the story afterward, since she later saves Lucas' life through her father's dreams, then helps bring Claus to his senses despite him being robotically controlled.
  • Reddas in Final Fantasy XII. His backstory reveals that he was the one Judge who nuked Nabradia with nethicite, and that leads to such a hatred of it that he destroys the Sun-Cryst, banishing the Occuria's influence from Ivalice and, in a sense, completing the Big Bad's not-so-evil plan.
  • Fallout 3: The player character's mother, Catherine. She has roughly 3 lines, dies within a minute of your birth, and is the driving motivation for James' escape from the vault (and try and restart Project Purity) and, consequently, your reason for doing the same.
  • Fire Emblem Awakening, as is the norm for the series, has a massive cast with most of the characters having little to no actual part in the storyline. Early on in the game, Maribelle, who herself has only a slightly larger part than most of the other playable units and loses all plot relevance shortly into the game, is held hostage by Plegia and used as a scapegoat to start its war with Ylisse, kickstarting the storyline as a whole.
  • The G-Man of Half-Life fame features, in the main, only in the intro and outro cutscenes of each game — his other appearances are mostly of the "you spot the G-Man in the distance, he walks behind a corner and vanishes" variety. (He does have a significant scene in the middle of Episode 2 when he gives Gordon a "heart-to-heart".) Everything about him is mysterious, but he's widely suspected of being responsible for, literally, the entire plot of the series from start to finish.
  • First Lieutenant McPherson of the Damned 33rd, from Spec Ops: The Line. Because of him, Walker decides to buck orders and turn Delta Squad's recon mission into a rescue op. And when they actually find him...

  • Feferi of Homestuck. In the alpha timeline, she doesn't get up to much, aside from establishing the dreambubbles by using her connection with the Noble Circle of Horrorterrors. The Feferis from other timelines are implied to have had a much bigger impact on their timelines, with one even ascending to God Tier, but aside from that, she's a minor character.

    Western Animation 
  • Dr. Henry Killinger has only three major appearances (with bit roles in few others) in The Venture Bros., but in each of those appearances, plays a significant role in shaping the Venture universe.
    • His first appearance in season 2's I Know Why the Caged Bird Kills has him rebuild the Monarch's organization and reunites him with Dr. Girlfriend. These events lead up to their marriage at the end of season 2 and their evil-doing abilities have gone up a a few levels ever since.
    • His second major appearance in season 3's The Doctor is Sin has him attempt to do the same thing for Doctor Venture and Venture Industries, but ultimately serves to give Venture a Heel Realization. Venture's Jerkass tendencies have been slightly lessened ever since, though he still falls into the Jerkass With A Heart Of Gold category more often than not.
    • His third appearance in the pre-Season 6 one-hour special All This and Gargantua-2, has him helping to build up and expand the Revenge Society into a legitimate super villain organization. He also kills the Investors and saves the Guild of Calamitous Intent after the Sovereign tries to Kill 'em All. It's a major shakeup in the Venture universe, to be sure.
  • Mr. Freeze had only five total appearances in the DCAU, but he frequently gets ranked as one of its most iconic villains.
  • On Avatar: The Last Airbender, Fire Lord Sozin was the one who started the war and Fire Lord Azulon probably did the most damage during said war, both were dead before the start of the series and got one flashback episode each, but otherwise are only occasionally mentioned.
    • The past Avatars as well, most notably Roku and Kyoshi.
  • Scooby-Doo! Mystery Incorporated has a few:
    • Harlan Ellison. He appears in a grand total of two episodes (though he's referenced as being on vacation in a third), and the first doesn't appear to be particularly significant to the show's Myth Arc. The second? It's the show's series finale, where he proves to be instrumental to resolving the plot. After the kids rewrite reality by erasing the Evil Entity, Ellison turns out to be the only other person who remembers the old reality, thanks to his experiments in speculative fiction. The show then ends with the kids accepting an invitation to travel to Miskatonic University, where Ellison works as a professor, and planning to solve mysteries under him as the new "Mr. E".
    • Danny Darrow. He only appears in the flesh in "Escape From Mystery Manor", but he also gives the gang the very first Planespheric Disc that they ever get their hands on. And much later, it's revealed that he's the lone surviving member of the Mystery Fellowship—the direct predecessor to the first Mystery Incorporated. Danny's appearance gives us our first real idea of how long the mystery-solving organizations have really been around, and the story of his descent into madness gives us our first real glimpse of the corrupting power of the Evil Entity. Even when Danny's not directly around, Darrow University is a major location in Crystal Cove, and the site of the collapsed Darrow Mansion is considered a major Crystal Cove landmark, reminding us of the Darrow family's enduring legacy. He's important enough that we get to hear about his ultimate fate in the new timeline in the series finale, with the revelation that he grew up to be dean of Darrow College and turned his family's old mansion into a historic site.
    • Abigail Gluck. She's a Posthumous Character, and only her corpse actually appears in the flesh. But she was also the Evil Mentor to Professor Pericles, and her amoral teachings apparently led directly to his Start of Darkness in his early days, and she was the original inventor of the fearsome Kriegstaffelbots that make up the bulk of Pericles' army after he recovers her old factory. Alongside Danny Darrow, she's one of just two characters from previous mystery-solving organizations (other than the first Mystery Inc.) to play a direct role in the series.
  • Walker in Danny Phantom only appears as an antagonist three times, but he's responsible for making Danny a Hero with Bad Publicity.
    • Freakshow might have been one, had it not been for Status Quo Is God. In his second (and last) appearance, he's responsible for revealing Danny's secret identity to everyone, including Danny's parents. However, after defeating Freakshow, Danny pushed the Reset Button on everything.
