Inexplicably Identical Individuals

[[File:officers jenny.jpg|link=Pokémon (anime)|frame|Shopped! I call sho-- oh, there really are that many of her.
 * (ahem) Carry on.]]

"Gordon Frohman: Morning, Barney! Didn't I see you just a second ago? Security Guard: No, that guy just looks and sounds a lot like me. I'm the real Barney, though. Second, Identical Security Guard: Like hell you are! I'm the real Barney!"

Why bother with Uncanny Family Resemblance, when you can have have every member of a family or even perfect strangers as the exact same person! Same taste in food, same way they style their hair, same profession, same mannerisms, and they all probably share the same Hive Mind as well. They may even all have the same name. This isn't just a Recurring Character—every town has their own. These are Inexplicably Identical Individuals; there's no reason for them to be perfectly identical—though the series may try to Hand Wave it as them being related—they simply are.

Occasionally, they fall into My Species Doth Protest Too Much, having one who's markedly different. The episode often revolves around them.

Compare and contrast to the game trope of You All Look Familiar. Also compare Single-Minded Twins. Contrast with the Recurring Extra, where it really is the same character(s) in every town.

Anime and Manga
"Brock: Jenny from Viridian City wears her skirt shorter than the other Jennys. The Celadon City Jenny uses styling gel in her luxurious hair! Saffron City Jenny wears exotic Vileplume No. 5 Perfume. Then there's the vivacious Vermillion City Jenny... [Misty carts him off the screen before he can continue]"
 * Originally named for Nurse Joy and Officer Jenny in the Pokémon anime. They likely arose as a parody of the games' use of You All Look Familiar. Some weren't even related, but they all had the exact same personality and appearance. The series did its share of Lampshade Hanging; at one point, one Jenny shows off a picture of her graduating class at the police academy (shown above), every single one of which is a Jenny. Regardless of whatever differences there are, Brock loves every last one of both kinds...and is able to tell them apart.
 * There was even a subversion, with a buff, tanned Joy that desired to stand out from her kin, as well as another time with a tough-acting Cowboy Cop Jenny who loves to take out criminal scum by...bowling.
 * The Magikarp Salesman, a recurring con-artist who tries to sell useless Pokémon to James (and has done so more than once), tries to pass himself off as a family of one of these to assure wary marks, but he's the same guy each time.
 * In one episode, Brock explains the subtle differences between the Officer Jennys when a bunch of them turn up to perform an arrest. Said differences included perfumes used, slight differences in skirt length, and slight differences in hair style - in other words, things that would be virtually impossible for audiences to see on a television (and judging by the fact that very few in the show notice them, they're not that easy to spot period). As he puts it:


 * For everyone else in the world (and the audience), the Jennys are told apart by having a different insignia on their hat to represent the town they're from. Joys, on the other hand, all have different colored crosses on their hats—Any color except red at the request/demand of the Red Cross.
 * In one episode of Diamond and Pearl, two young Nurse Joys were shown, giving them first names and establishing Joy as a family name. Their mother was also a Joy, but their father was a normal man.
 * Best Wishes shows that Unova has somewhat different Jennys and Joys. Both have different uniforms compared to the other regions, and Jenny's hair is a lot shorter.
 * Unova also has runners of the Battle Clubs named Don George.
 * Pokémon Special plays this trope for drama when it's noted that all the Galactic Grunts not only look identical, they all move and act like they have a Hive Mind, hinting that they have no free will of their own.
 * As does Pokémon Diamond and Pearl Adventure, where eyes go from brown to green when she's a part of Galactic. The grunts themselves have quite a bit of personality though.
 * As a matter of fact, almost all the evil team grunts tend to look similar to each other in Pokémon Special, however, the Team Plasma grunts have a wide variety of faces and body types.
 * Each region also has its own Chairman, Fan Club President, and announcer guy.
 * Sister Princess had one person who was a butler/real estate agent/antique salesman/boat captain and anything else that was needed on the island. But they were all different people. At the second to last episode it's revealed that they.
 * The protagonist of Elf Princess Rane (who is not the title character) has about twenty older sisters, the product of repeated sets of quads and quints, who all look exactly alike. (Five of them have formed a rock band.)
 * In Galaxy Angel, the bad guys of the episode are always the same few people, with the same few voice actors (except the one episode that featured the fake Angel-tai, and a few where Chitose snaps). Nobody seems to notice, but with the show's Negative Continuity, it's not a surprise.
 * In fact, it happens with a lot of disposable characters, due to the show's low male population. Compare every man Ranpha drools over, or every kindly shopkeeper...
 * In The Vision of Escaflowne, an entire army of warrior-monks has exactly the same character design. Especially egregious since multiple scenes feature dozens of them on-screen at the same time.
 * The representatives sent by Shirase's various clients in every arc of Battle Programmer Shirase all have the same face, voice, and even name (Kaoru Akizuki), but wear different outfits according to their occupations. They even have the exact same internal conflict when seeing Shirase doing (seemingly) inappropriate things with an underage girl, followed by the same conclusion and Catch Phrase, "I'll pretend I didn't see anything!"
 * Played with in Lucky Star: Every character that isn't a recurring character has the character design and voice of the same middle-aged woman, with the design only being changed if situation demands it, and even then it's always the same voice. Once, several of the same middle-aged woman were on screen at the same time, and at another time three different girls were on screen speaking with the same voice! (If it isn't the middle-aged woman, it's usually Minoru Shiraishi making a guest appearance on the show.)
 * Pani Poni Dash! does this to any non-important student in the school. All the classrooms are filled with carbon copy clones of a generic boy and girl, or a fat girl named Ito. At the end of the first episode, The new homeroom teacher, Rebecca Miyamoto lampshades and justifies the importance of those other students by taking a roll-call by listing off the names of all the important girls..."And everyone else."
 * In Rurouni Kenshin, one of the peripheral characters the cast interact with is Tae, a Yamato Nadeshiko waitress. When they go to Kyoto, they meet her identical (in personality and appearance) sister Sae, who is also a waitress.
 * Nagasarete Airantou: Suzu looks just like her mother at the same age. This isn't merely a case of genetic relation though; Fujishiro Takeshi pretty much just drew Suzu in the flashback chapters and called her "Suzuran." The only difference is their bust sizes.
 * Kuina and Tashigi of One Piece. They look identical and fans for the longest time theorized that they were either the same person, or twins (as well as wrote many a fanfic, to torment Zoro with this idea). This was officially disproved by Eichiiro Oda himself, who said pretty straight-forwardly that they were not in any way related and just for some reason happened to look alike.
 * There are two girls called Nago in Daily Lives of High School Boys, one being the staff of a pizzeria Tadakuni works part-time and the other being Yanagin's Rival. They look suspiciously alike; the latter Nago is essentially a cleaned up version of the former, wear red bandanas, and they go to the same school as well. The problem is their names are written with different kanji—the former is 奈古 while the latter is 名護. While Word of God already declared they are different people, speculation are still abound.
 * Naruto's Rock Lee and Might Guy are apparently not related.
 * In Yu-Gi-Oh!, during the Battle City arc, Kaiba has a command center monitoring every duel, the monitors being females who all look and dress exactly the same - white suits over tan shirts, high-tech specs, and a bobbed hairstyle with bangs - the only difference between them being hair color. Fans often refer to them as "clone girls", but no explanation for this is ever given.
 * The members of the Morals Committee / Mallard Team in Girls und Panzer, while not related to each other, are distinguishable only by minor differences in their hairstyles. (The the original Japanese but not in the English dub, they even have the same voice actress, Shiori Izawa.)

Comic Books

 * In the G.I. Joe comic books, Cobra's elite troopers - the Crimson Guard - all underwent extensive plastic surgery to look like one of a handful of "original models." This allowed Cobra to infiltrate society by having its troopers take positions of importance in the local community; if one was killed, he could be replaced by a duplicate.
 * This achieved Fridge Brilliance with the years-later reveal that Cobra Commander is . The real reason for the "Fred" series of Crimson Guard was so that the paranoid Cobra Commander would have an his treacherous lieutenants.
 * In their original appearance (and thus prior to at least two RetCons), the Zamarons, a race of Amazon-like Warriors In Space! (later revealed as female ) always chose their queens from humanoid females who met an ideal physical model, and thus always looked alike. They would take a prospective candidate from her home planet, explain that she was going to be their new Queen, and then give her super-powers by playing some kind of alien musical instrument at her (!) and presenting her with the gem that gave her a name—the Star Sapphire. Naturally, Earth had a candidate for the role --.
 * In Carla Speed McNeil's "aboriginal Sci-Fi" series Finder, one of the main cities in the series is run by several different "clans." Most of these clans, in addition to a common name, share common features. The Llavrics are all women (yes, even the men are women. They are physically formed to be able to "tuck it in" with ease), and not just any women, the same slim, blonde woman. They all tend to be a bit on the artistic, dramatic side. The Mediwar clan has distinct male and female versions that are identical within their gender. They run military, police, and medical branches of the government, which leads to the fantastic insult - "copface." (Try that one on Officer Jenny!) These clans are most emphatically not made up of clones and not everyone born to clan parents is automatically given full clan status. There is a yearly examination which could be similar to defending a thesis - or winning a beauty pageant. It all depends on your clan. Clan members can and do intermarry and procreate (they're all human, after all); genetics determine if the offspring resemble one parent over the other.
 * Thompson and Thomson in Tintin; the only difference is in the mustache. Furthermore, it's explicitly stated that they're not twins or even related.
 * In The Muppet Show Comic Book: On The Road, the Muppets, on tour following the destruction of the theatre, keep encountering familiar-looking elderly hecklers. Two farmers (one of whom is apparently Waldorf's cousin); Mitch Wacky's gagwriters Stadler and Waltorf; the entire population of Little Statwald...
 * In every Pink Panther comic book story, the panther runs into a foul-tempered, moustached short man with a big nose who looks exactly like the foul-tempered, moustached short man with a big nose from the previous story. He keeps running into these guys in the animated shorts as well, but not as consistently.

Film
"Anakin: In fact, I'm pretty sure it's... Amidala's decoys Sabé and Eritaé. Eirtaé: Actually, I'm Eritaé! Sabé: And I'm Sabé!"
 * The Sheriff in Quentin Tarantino movies might be part of a group of Inexplicably Identical Individuals, since he seems to be Sheriff over a fantastic number of jurisdictions, as well as dying in his first appearance.
 * According to the IMDB pages for Dusk Till Dawn, Kill Bill, and both sections of Grindhouse, they really are all the same character. Then again, we're not sure what the timeline is for all these movies.
 * The 1960s movie Those Magnificent Men in Their Flying Machines features one of the characters, a Frenchman named Pierre Dubois, consistently trying to greet a girl he has met before, only to realise that it is a completely different girl. The girls, Bridgitte, Ingrid, Marlene, Yvette and Betty are all the same actress, each with an offensively stereotypical accent from a different European nation.
 * In the 2002 film Big Trouble, Andy Richter plays a mall security guard who claims to have a relative who works in airport security. Sure enough, Richter later shows up in an airport (this time with a mustache), working security.
 * That one is straight out of the book the movie was based on, Andy Richter was a perfect touch though...
 * In The Phantom Menace, Queen Amidala's handmaidens all look identical. This, of course, is intentional, and part of the "decoy trick", where one of them, Sabé, posed as the Queen while the Queen dressed as one of the handmaidens in her identity as Padmé. They have similar names too, at least in public; in addition to Sabé, the others were named Eirtaé, Rabé, Saché, Yané, Fé, and Dané; Padmé's name mentioned often make members of the royal court assume that the Queen has eight handmaidens. This Trope is lampshaded in the Star Wars: Clone Wars comic book In Triplicate with this exchange:


 * In the course of the Spider-Man movies, Peter Parker has encountered a wrestling emcee, a snooty usher, and a French waiter who all look exactly like Bruce Campbell.
 * It would have been Fridge Brilliance that he was Mysterio and presumably staking out targets. It just makes Peter Parker look like a dumbass for not noticing.
 * Yeah, because anybody who doesn't instantly recognize a face they've seen for a couple of minutes once every few years is a total dumbass.
 * Similarly, there are Stan Lee's cameos in almost every Marvel movie. It's conceivable that the Stans in the Spider-Man series are all the same guy, but the Stan in X-Men: The Last Stand is in a flashback and would have to be twenty years older than the Stans in the first two films. Also, in Fantastic Four Stan plays mailman Willy Lumpkin, but in the sequel he identifies himself by name as Stan Lee (though maybe it's actually Willy Lumpkin pretending to be Stan?).
 * Likewise, Stan Lee looks exactly like Hugh Hefner or possibly just some other guy named "Hef" who likes the ladies.
 * And there is one in Daredevil that's also in a flashback, saved from an incoming car by kid!Matt, only to realize surprised that the kid who "saw" the car is blind.
 * Captain America shows him to be alive and look exactly the same age in the 1940s. Possibly a case of Identical Grandson?
 * In Joe Versus the Volcano, Meg Ryan plays three different characters. Two of them are sisters, but the third is someone completely unrelated.
 * In Night at the Museum 2 Amy Adams plays Amelia Earhart and a woman who visits the museum at the end. Larry attempts to invoke Identical Grandson by asking if she was related to Earhart, but Adams responds "No, I think I just have one of those faces, you know?".
 * In Shaun of the Dead Shaun's group, sneaking around an alleyway between houses, bumps into another group of survivors led by Shaun's ex, Yvonne. As the two groups pass, it becomes clear that each of Shaun's group has an exact counterpart in Yvonne's gang. The incident is never mentioned again. In the director's commentary, Edgar Wright calls this group the 'doppelgang'.

Literature
"After six months of surgery and psycho-conditioning, he was identical to the 469 other Mr Prestos and to the idealized portrait of Mr Presto which hung behind Presteign's dais ...a kindly, honest man resembling Abraham Lincoln, a man who instantly inspired affection and trust. Around the world purchasers entered an identical Presteign store and were greeted by an identical manager, Mr Presto."
 * From Discworld, we have the CMOT Dibblers, who due to the "laws of narrative" have a slightly different version as part of every culture on the Disc, complete with Catch Phrase.
 * More mildly, the Igors are not identical, but are difficult to tell apart, and seem to have no trouble talking about each other, despite having the same name.
 * Unusually for this trope, it is later justified in-world with the observation, in later books, that the Igors are an extended family who view their "pioneering" self-modification as a family tradition, even suggesting that some modifications are intentionally uniform, and act as "clan markings".
 * They also can remove all their scars from those modifications, but keep them for identification purposes.
 * The Dibbler phenomenon has been extended. Jingo, The Fifth Elephant and The Amazing Maurice and His Educated Rodents all feature guards in different Discworld towns who resemble the inept backbone of the Ankh Morpork Watch, Sergeant Colon and Corporal Nobbs.
 * Amusingly, Terry Pratchett says that at nearly every book signing, a police officer will come up to him and say he knows a Colon and a Nobby at work. Once, it was a clearly a Nobby telling him this.
 * Literary example: Mr. Presto in Alfred Bester's 1956 novel The Stars My Destination (aka Tiger! Tiger!), who is very creepy in that these used to be individual people until they were surgically altered and reconditioned to be identical in every way. Indeed it is actually something of a deconstruction of the concept.


 * The opening to the superhero anthology Temps, devised by Neil Gaiman and Alex Stewart, has "at this point we found ourselves with two hundred identical female babies." All became "equally inept" secretaries at the Department of Paranormal Resources. Consequently, "whichever branch they went to, there she was."
 * The Belgariad series by David Eddings features a queen named Salmissra. For thousands of years, her country has been ruled by a Salmissra, all looking and acting as identical as humanly possible. Whenever the current one is getting a little long in the tooth, twenty little girls are rounded up from across the country, all chosen by comparing them to a picture of the original Salmissra. They spend the next ten years being trained in the correct mannerisms and habits, and the one who is deemed the most like the original Salmissra is elevated to the throne. The other nineteen are killed. For what it's worth, the country is inhabited entirely by inveterate drug users, and the rest of the world find the Salmissra fixation just as creepy as the readers do.
 * That's probably a trope in itself. There are many, many examples of legacy rulers in fiction (or Dread Pirates or whatever) (more than one in the Belgariad itself).
 * In the science fiction novel Counting Heads by David Marusek many standardized jobs are done by clone lines including a line of nurses known as jennys.
 * Played with to deliberate comic effect in one issue of Perry Rhodan, in which the 'king' of a cosmic scrapyard employs a large staff of suspiciously similar-looking individuals with suitably imposing titles...all of which are actually just himself in paper thin disguises. Visitors are advised to play along with his act, of course.
 * Also tinkered with in the novel Bones Of The Earth, which features what is apparently a race of identical beings from the future, but who turn out to be which travelled  an immense number of times.
 * The Thursday Next series of books by Jasper Fforde has an army of Mrs. Danvers, created when hundreds of "generics" (BookWorld inhabitants who haven't yet developed into characters) imprinted on her. The same thing previously happened with T.H. White's Merlin, which is why there are so many eccentric wizard mentors in the BookWorld.
 * An arguable example might be Felix-8, the last of a series of people the fiendish Archeon Hades has transformed into an exact duplicate of his deceased favourite henchman, Felix Tabularasa.
 * An interesting variation is used in the Of Man and Manta trilogy by Piers Anthony; and is justified in-universe. The trope is deliberately invoked with a type of law-enforcement investigator known as an "Agent", of which there are multiple "series". Agents are surgically modified as well as mind-wiped and reprogrammed, so that all agents of a series are indistinguishable from each other (it's never stated how many agents are in a series). This is describe in-universe as a way to automatically compensate for differences in observer bias, thus easily eliminating those differences as a variable when evaluating their reports. Agents who are in the field long enough to develop individual personalities are considered unreliable, and are mind-wiped and reprogrammed as soon as possible.
 * Not only to make them functionally identical; but any special skills or abilities learned by an Agent in the field are included in the programming for the next series.
 * Somewhat inverted in the series Replica about a set of thirteen perfect female clones who all look alike and are perfect at everything they try to do (their speed rivals Olympic athletes, they are inhumanly intelligent and strong and fast etc etc). Though all of the Amys have the same name, when the scientists send them out into the world for adoption, some are renamed (Number Nine becomes Annie, Number Ten becomes Aimee, and Number Thirteen becomes Aly) and all develop separate personalities.
 * The Ursula K. Le Guin short story Nine Lives involves a "family" of ten clones, both male and female, all of whom were made from a particular genius and who are all accordingly also geniuses, highly trained in a variety of fields. The other two non-clone characters are fascinated by them and by the fact that none of them can ever be truly alone. They're all very close.
 * The plot of The Prince and the Pauper revolves around this.
 * When Miles Vorkosigan first wakes up after being dead, he's very confused to encounter the same woman (Doctor Durona) at, apparently, three different ages. His worry that he's somehow skipping years at a time is exacerbated when he then meets the younger versions of her again.

Live Action TV

 * Babylon 5 gives us 10 identical brothers named Zathras, all with the same speech pattern, philosophical attitude, and accent, all played by one actor (Tim Choate). "No, that was not Zathras, that was Zathras. There are 10 of us, all of family Zathras, each one named Zathras. Slight differences in how you pronounce. Zathraas, Zathras, Zathras...You are seeing now?"
 * Worth mentioning that the slight differences in pronounciation are just almost too subtle for human ears to recognize, unless the name is spoken REALLY slowly.
 * Tom Poston played at least three completely unhelpful clerks on Home Improvement. At least two of them were brothers.
 * On Sliders, no matter how many centuries of Alternate History divided one Earth from the next, any roles for a cab driver, desk clerk, or bartender tended to be filled by counterparts of the same three men.
 * Bizarrely, the desk clerk was Other Darrined for the final two seasons, acquiring a very different accent, weight, and personality, with only his job and the name "Gomez Calhoun" linking him to the original version of the character. Considering that those seasons used a different hotel in a different city, it would have made far more sense just to name him something else.
 * In the British anti-sitcom The Young Ones, Alexei Sayle plays the boys' landlord, Jerzei Balowski. He also plays every one of Jerzei's "brothers" and "cousins", all of whom posses varying degrees of sanity, and are prone to launching into sudden, entirely non sequitur stand-up routines. Strangely, the boys seem to be able to differentiate between the different Balowskis, even asking, "Who are you?" to ones they haven't met yet, and insisting that one of the more insane ones leave immediately (he doesn't).
 * The infamous Monty Python's Flying Circus pet shop sketch does this not only with the pet shop owners (the same save an obviously fake moustache), but the shops themselves, which are called Similar Pet Shops ltd.
 * The Emergency Medical Hologram from Star Trek: Voyager makes a cameo on the Next Generation film Star Trek: First Contact. This and at least one other appearance in Voyager's "Author, Author" is because he is one in a series modeled after the father of all holograms.
 * The hologram designer also appeared on an episode of Deep Space Nine to create a new model of hologram based on Dr. Bashir. The prototype hologram of Bashir plays an unfortunate part in the accidental reveal that Bashir was a subject of, the fallout from which resulted in the project being scrapped. It's too bad really, those dreamy eyes and charming voice could have been on every Star Fleet ship in the galaxy...
 * The Peter Serafinowicz Show had a Big Brother parody (to the point of using the same graphics from that year's show and even the theme tune) called Mike House. All eight housemates were the same person.
 * In The Prisoner, Number 6 quickly finds out all the maintenance guys look exactly the same.
 * Like the Big Trouble example above, Andy Richter played five identical quintuplets, one of whom is himself, in Arrested Development.
 * Xena: Warrior Princess: Xena had three lookalikes who switched places with her in various episodes (Diana, Meg, Leah), plus two other characters Lucy Lawless had previously played in Hercules (Lysia, Lyla), plus two 20th/21st-century reincarnations (Melinda, Annie), plus a modern clone, plus a Mirror Universe twin.
 * Xena isn't the only one though. Ares has a doppelganger in the form of King Iphicles, half-brother of Hercules, and Karl Urban plays both Cupid and Julius Caesar.
 * On How I Met Your Mother, each main character has a doppelganger (played by the same actor, of course).
 * Diplomatic Immunity, whose main characters run the consulate of the fictional nation of Fe'ausi, introduces a second fictional nation the whose consulate is run by...the same actors as the main characters, with wigs.
 * Especially weird example: There are two different hosts of Cash Cab, one for the original and one for Cash Cab: Chicago. The female Chicago host looks just like the original male host, but with long hair. She even has the same mannerisms and speech patterns, for the most part. Note that they are not related, and this is almost certainly coincidence.
 * Kenji Ohba has played two separate characters in Super Sentai History, Battle Kenya in Battle Fever J, and Denzi Blue in Denshi Sentai Denziman and has reprised both roles during Kaizoku Sentai Gokaiger, Denzi Blue in the 199 Heroes movie and Battle Kenya during the Christmas themed episode 44. He's also reprising his lead role from Space Sheriff Gavan in its Crossover movie with Gokaiger and according to The Other Wiki both his Sentai roles will be putting in an appearance as well.
 * Your Mileage May Vary about how "inexplicable" this is, but the Patty Duke show featured, as the theme song reminded us, "identical cousins" Patty Lane and Cathy Lane. They looked alike (of course, as they were both played by Patty Duke), but had different personalities and hairstyles.

Newspaper Comics

 * Scott Adams hangs a Lampshade on this in Dilbert with Ted, the generic guy (his real name). People who have known him for years can't describe him. There may be more than one Ted in the company no-one really knows.
 * There are. Ted is just the name that Scott Adams uses whenever he can't think up a better one and it's not important enough to matter.
 * Every saleswoman, customer-service representative, and waitress in the comic strip Cathy has the same appearance and name (Mabel). We're supposed to understand that these aren't really the same person, but whenever Cathy is acting like a difficult customer, we always see "Mabel" in the role of being put on the spot and having to deal with Cathy.
 * One of Bill Mauldin's wartime cartoons has two U.S. soldiers walking through a French town, and one remarks, "This is th' town my pappy told me about." Every civilian in sight (six of them, including a woman), looks just like him.

Radio
"'Jack Benny': Oh, Sir, Sir. 'Frank Nelson': Yeeeeeeeeeeeeeeeeeeeeesssssssssssss? 'Jack Benny': You work at this airport too!? 'Frank Nelson': No, I'm just a DC-4 with a mustache. 'Jack Benny': Oh, never mind, I just want to know: Do these planes go to New York? 'Frank Nelson': Oooooooooh, Do They!"
 * This was Frank Nelson's role throughout his career, and one he served with extra ham. Frequently Homaged, especially in The Simpsons. A typical routine might go:


 * Later lampshaded in an episode of the TV show in which Jack worriedly relates to a psychiatrist (with flashbacks) how he keeps seeing this same guy, no matter where he goes.
 * The various members of the Hardthrasher, Sternbeater, Whackwallop and Grimpunch extended family in Bleak Expectations, all voiced by Geoffrey Whitehead. (Each episode features a different brother; each season a different set of brothers who are cousins of the last lot.)
 * The original I'm Sorry Ill Read That Again serial, "The Curse of the Flying Wombat" featured Tim Brooke-Taylor as Lady Constance, and later as Lady Constance's sister Hurricane Flossie. Later serials, despite the best effort not to have Tim playing half the characters, seemed to keep churning up Lady Constance clones.

Theater

 * In the show Next to Normal, Dr. Madden and Dr. Fine are played by the same actor. The two doctors aren't supposed to be related in any way.
 * The actor playing Cinderella's prince in Into the Woods also traditionally plays the wolf.

Video Games
"'"Faerie Walnut?! Oh, please!"'"
 * In Secret of Mana, nearly every town had its Cannon Travel Man (who were apparently a set of identical quintuplets).
 * Another staple of the Seiken Densetsu/Mana series is the dancing turbaned storekeepers (Mr. Moti), who all look like King Amar III of Kakkara.


 * Legend of Mana, on the other hand, seems to think that it's all the same Mr. Moti. His character profile reads: "He is everywhere, doing everything."
 * Salescat Neko seems to fall under this trope due to his appearance in multiple out of the way areas, but it is implied that it is just one Neko who is traveling the world. (You do get to meet his palette-swapped relatives in Seiken Densetsu 3, through.)
 * Jeane is one of the few recurring characters in the Suikoden series, despite the fact that it spans several different continents and several hundred years. Lacking any of the obvious methods of attaining immortality, the developers and Jeane herself have hinted that she simply has a whole lot of suspiciously identical sisters. A scene in Suikoden V, however, does seem to indicate that she's a LOT older than she seems...she manages to confuse the shell out of an ancient Tortoise, who claims to have sensed 'a being of great age', but instead finds a voluptuous, scantly-clad young woman when he comes to investigate. She is also shown to have a mysterious connection to an ancient civilization that was destroyed centuries earlier. Thus, it remains a mystery whether the "identical family" explanation was humorous, or if Jeane is simply less human than she appears.
 * The makers of this series seem to love encouraging epileptic trees with her. Numerous explanations are hinted at.
 * Jagged Alliance 2 has the De Santos bartending brothers, generic booze vendors who look, sound, and act exactly the same. The black sheep of the family, Manny, only looks exactly the same, and hasn't quite managed to land that bartending job yet.
 * The Support Reapers in The World Ends With You come in two breeds - red-hoody-baseball-cap and black-hoody-red-bandana. Only two of them (BJ and Tenho of Def March) ever get names.
 * The RPG Exile III/Avernum III had an enormous amount of towns, and did a good job in making all the NPCs and shopkeepers unique with the exception of the fletchers, dressmakers, provisioners, and...Pat, who were all alike and had all the the same exact dialogue. They just had a lot of cousins.
 * And in Exile 1, the initial description of the guards in Silvar would end with. "You wonder why he looks exactly like all the other guards."
 * The LucasArts adventure Sam and Max Hit The Road featured a variety of different locations...plus three Snuckey's burger bars, in different corners of the country, with the exact same pimply youth (who resembled Bernard from Day of the Tentacle) staffing them. They had slightly different merchandise on offer, but the guy was exactly the same except for one feature (one had a mustache, another had no hat, and the third had a different tie).
 * In  Izuna: Legend of the Unemployed Ninja , the innkeeper is an elderly woman named Ume. In the sequel's first town, the heroes see Ume, complete with the same profile picture...except it's not their Ume. She has the same personality, but she doesn't recognize any of the main cast. Shino mentions that "it is said that up to three people in the world can share the same face at the same time," although the others were unsure about sharing the same name. As it turns out, that was a little too literal, as they see the third person with the same face in the next town, who is also named Ume. The original shows up later when they return to Kamiari Village (the setting of the first game).
 * This continues further, and by the time they find the fifth Ume they give up on ever trying to figure it out.
 * In Super Paper Mario, every convenience store that Mario and the others find is run by Howzit, with the exception of the one in Flopside, which was instead run by Notso.
 * In Animal Crossing, every town has the same resident shopkeeper, the same postal employees, the same museum curator, the same policemen, and even the same mayor.
 * Valkyria Chronicles has a cameo character from Skies of Arcadia whose name is supposed to be Fina, but is designated "Medic" throughout the game. It is revealed in the Encyclopedia Exposita that they're identical triplets who are all serving as medics, named Fina, Hina and Mina.
 * In Ratchet and Clank Future Tools of Destruction, the Grummels come in 3 varieties depending on what they sell. Explained by them being clones of the last Grummel (although that does not explain the 3 different types, but one can just assume genetic engineering or something).
 * Officer Chunk is guarding the art gallery early in Vampire the Masquerade: Bloodlines, and later mans the front desk at the Venture Tower (he got fired for letting you get into the gallery). However, if you got by him by killing him, the one at the tower will be an identical relative of his. And on a minor note, there's the hordes of identical NPCs going around the areas. It's not uncommon to see a group of redheaded quadruplets dancing at the local club.
 * In My World, My Way, this is subverted; all the minor NPCs in each town claim to be different people despite looking exactly the same. The subversion is that they really are the same people; they're in fact actors hired by someone to fool the protagonist.
 * In The Secret of Monkey Island, the wandering pirates on Mêlée Island's map (the ones you have to learn the Insult Swordfighting phrases from) are all identical, except some have hair or some form of headgear.
 * In Final Fantasy IV, there's a guy called Namingway who keeps appearing in every town and asking if you want to change your name. Toward the end, you find a city on the moon inhabited by guys identical to him, called "Hummingway Home". And he's there, too.
 * All the similar-looking shopkeepers in Dragon Valor are somehow related.
 * Half Life is a shameless offender, with all the security guards having the same appearance and voice. This however is excusable due to there being very little variety in character models to begin with.
 * Amusingly subverted and parodied with Sabu in Bangai-O, who appears several times as a boss. Riki and Mami initially assume that he is multiple people (somewhat helped in that bosses' mechs get blown to smithereens). Soon enough, they end up seeing him as the same guy...but he doesn't recognize them, at first (much to Riki's annoyance).
 * The Harry Potter PC games had all the main characters and a lot of background students you could interact with. To save time designing individual characters when they didn't have to, they had about six different designs for the background students and just made a lot of copies of each one, so that all the background students were identical to half a dozen others.

Webcomics

 * Similarly, there's Akbar, from 8-Bit Theater. Of course, he's only pretending to be a dozen unrelated people. Here's one
 * While not exactly a web comic, the short "series" of hentai comics Daily Life with a (monster girl)(NSFW), features the lead male as being a family of brothers who all look the same.
 * The thrice-abandoned webcomic Spells And Whistles featured a recurring individual called T (who looked exactly like a certain member of The A-Team) and his lackey (lower-case) t who turned up several times in odd places, each time with a different profession. It was never made clear if it was the same guy over and over or a whole bunch of guys with the same names and faces, though the comic's fans largely believed it to be the latter.
 * Real Life Comics does this with the character Alan Extra, who is...well ...
 * The webcomic Monster Commute has a string of "convenience" stores called Oni Oni Mart, to quote the site: "Owned and operated by Toni Oni, One employee; Toni Oni and aspects of Mr. Oni, Over 800,000 locations currently known."

Web Original

 * Agents of Cracked features a rival website to Cracked.com called Broked.com, which is more than willing to steal Cracked's jokes. When Michael and Daniel eventually go to their office, they find other versions of themselves working there.

Western Animation
"Aang: Aha, I knew it! I knew you were the same guy. You're the shop owner and the boat guy. Dock/Xu/Bushi: Oh, you must be talking about my brothers, Dock and Xu. Aang: No, I just saw you! You switched hats and called yourself a different name! Dock/Xu/Bushi: Oh, you know who does that? My brother Dock. He's crazy."
 * Goofy cartoons in the Classic Disney Shorts canon often feature a universe where EVERYONE looks like Goofy. This is most evident in sports cartoons like "How to Play Baseball" or "Hockey Homicide" where both opposing teams are made up of Goofy clones.
 * The special Garfield in Paradise had a Great Gildersleeve-style sleazy salesman type show up as a hotel clerk and then a car rental agent successively, prompting the lines, "You look familiar." "I have a brother in the hotel business."
 * He's in the comic strip, too.
 * And, of course, the snake-oil salesman from Family Guy, who's done over a dozen sleazy, disreputable sales jobs by now.
 * Futurama has a character called Sal, a fat slob who turns up in every menial position that the script required. The writers haven't yet gotten around to deciding whether there is just one Sal who constantly flits from job to job or some factory somewhere that was pumping out thousands of Sal clones, though DVD/Bluray commentary hints at the former. The same series has an Australian Man who is always doing menial labour.
 * Ditto the "Squeaky-Voiced Teen" (later revealed, during his time as Store Manager of the Springfield branch of Foot Locker, to be the son of Lunchlady Doris, and having the last name Friedman, both at roughly the same time) and "Sarcastic Man" in The Simpsons, as well as Lindsey Naegle, who's always an executive, but not always in the same company. She is accompanied by different people in different companies, but there is a recurring male executive from season 12 onwards. One executive claims that killing them creates two more.
 * Also, in "Marge and Homer Turn a Couple Play" it was revealed that there are multiple Duffmans that look, sound and act exactly the same.
 * Duffman isn't inexplicable though. He's a professional mascot played by different actors.
 * Lindsey, however, has admitted she changes jobs so often because "I'm a sexual predator."
 * When Homer was once banned from Moe's Tavern, someone came in the bar looking like Homer with a bad disguise as a wealthy person, complete with top hat, cane and monocle. Believing it was Homer, Moe got infuriated, and the barfly beat him up and threw him outside. Cut to a depressed Homer walking outside and noticing the man looking like him, but is then distracted by a dog with a puffy tail.
 * The Red Guy in Cow and Chicken and I Am Weasel.
 * They hung a lampshade once in I Am Weasel, and occasionally in Cow and Chicken more than one Red Guy would appear in the same scene together (Journalist Geraldo Rear-viewah meets warden Ben Pantsed).
 * The opening scene even lampshades it, as Red Guy reveals a whole plethora of Red Guys, each with a different outfit.
 * They're not always different people though: One I Am Weasel ep had the titular character sent to prison by an obscure law pointed out by a Red Guy attorney only to find a Red Guy warden. When he asks the latter if they are one and the same he denies it while acting quite nervous.
 * In the Back to The Future animated series, no matter where you went and what time period you were in, there was always a Biff. And no matter how many generations removed from the "normal" Biff, they were identical except for their period clothing. Those are some strong genes.
 * Parodied in Avatar: The Last Airbender. The storekeepers appear to be a set of Inexplicably Identical Individuals, differing only by their hats. It is actually just one old man that's gone insane from eating deformed fish from a horribly polluted lake. He acts as if they're different people even when he changes right in front of people:


 * Deconstruction: Also taken to creepy extent with Stepford Smiler Joo Dee. When the gang tells the first Joo Dee about the Fire Nation approaching Ba Sing Se, she's taken out and replaced with someone who looks similar, but is still quite distinct, and still identifies as Joo Dee. The gang later finds out that several similar looking women are all brainwashed into being "Joo Dee." The name is actually the Chinese equivalent of "Jane Doe".
 * Rancid Rabbit in CatDog.
 * Mr. Hollywood from Two Stupid Dogs (the big guy with the Texan accent and the catchphrase "Isn't that cute...but it's WRONG!")
 * The Debbies from The Oblongs tend to act like a hive mind and act exactly the same.
 * The shopkeeper from Ned's Newt that sold Ned the newt makes frequent reappearances as an extra. Sometimes more than one of him would appear on screen at once.
 * Courage the Cowardly Dog had the General and the Lieutenant, who were alternately policemen, captains, security guards, ninjas, and so on. The "Lieutenant" often appeared alongside identical versions of himself.
 * Played with in Stroker and Hoop. One of the voice actors plays a different background guy in almost every episode (usually with only one or two lines). It turns out

"''"Wait, don't I know you?" "No, you must mean my sister. Or my cousin, or my granny...Maybe half of the east coast, I don't know -- there are a lot of me."''"
