He Who Must Not Be Seen

A regular or Recurring Character that is never seen on screen. There are three variants: The Voice, The Ghost, and The Faceless.

See also Ultimate Evil. Compare with He Who Must Not Be Heard.

Anime & Manga

 * The Dancing Giant ghost in Haunted Junction is only seen from the knee down, and generally only one leg at a time. He's that big.
 * In Taro Kid/Skyers 5 (name varies depending on jurisdiction) the Big Bad (head of a SPECTRE-like criminal organization) is only ever seen from behind his chair.
 * Partial example: Tsunade from Naruto always makes herself look much younger than she is, and on the couple of occasions where she was exhausted enough that the illusion fades we're prevented from getting a good look at her. What little we do see implies that she actually looks older than she really is, no doubt due to the life-shortening effect of her ultimate healing technique.
 * Astro Boy's Lord Deadcross.
 * Ai Enma's "grandma" from Hell Girl. Although she talks, all we ever see of her form is her silhouette. The only human that takes a good look at her is completely horrified by what she saw.
 * The Sacred Ancestor, the Vampire King Dracula remains unseen save for flashbacks where he receives no physical description save for his eyes in all mediums of Vampire Hunter D.

Comics

 * Ben Grimm often speaks fondly of his dear Aunt Petunia, but she's never been seen.
 * Actually, Fantastic Four #239 featured her in person. It's revealed that she is a young woman married to his Uncle Jake.
 * In the early Spider-Man comics Mary Jane was only referred to and fully seen, although one story did featured a brief cameo we could only see her body and not her face. It would be over two years before readers received their first full glimpse of her in the comics.

Films

 * In the 1980 Claymation educational film Dinosaurs!, neither the main character Phillip nor his classmates are ever actually shown, and his teacher is only briefly seen from behind. When this film was released to home video in 1987, new scenes were added with Phillip being played by Fred Savage. The new footage featured Phillip's unseen mother, as well as a mysterious female voice who educates him on dinosaurs.
 * The supposed god in 10,000 B.C. makes sure no ones sees him to add to his whole mystique. He even had all blind servants.
 * The Soviet premier in Dr. Strangelove.
 * Roxy Carmichael from the 1990 movie Welcome Home Roxy Carmichael.
 * Mainly because he's in Russia, which is only shown in the movie as a background-shot.
 * The Blair Witch in The Blair Witch Project is never seen on camera, only spoken of and feared. This of course makes her all the more scary!
 * Blofeld (yeah, him) actually started out this way.
 * Sir Not Appearing in the Film from Monty Python and The Holy Grail.
 * But he does appear very briefly, in the illustration on his page of the storybook. From the looks of things, he must be the youngest knight of them all...
 * The man directing the criminal organization in The Testament of Dr. Mabuse is only shown as a silhouette behind a curtain giving orders. It's later revealed that
 * Floyd Thursby, the murder victim in The Maltese Falcon.
 * The title character in Edward, My Son is never seen onscreen. Everything we know about him we hear from other people.
 * Much like Dr. Claw Mr. Feather's boss "The Man" from Undercover Brother only the back of his head and his hands are seen.
 * The 1976 biopic of the Prophet Mohammed (US title The Message ) complies with Islamic law by never showing the Prophet or any of his immediate family. This leads to a lot of very meaningful shots of his camel and his camel-goad.

Literature

 * Let's not forget the "Once-ler" and all his friends and relatives in Dr. Seuss' The Lorax, of whom only their hands are ever seen. Probably to make them less sympathetic.
 * Sauron of The Lord of the Rings. This, despite his being the novel's Big Bad and Ultimate Evil. The title is even a direct reference to him (the Lord of the Rings).
 * Pippin, Aragorn, and Denethor see him face-to-face through the Palantír. Denethor explains Sauron's hidden nature as being due to the notion that all wise persons of power use others to do their fighting for them; however the story indicates that this is the act of dictators (like Sauron, Denethor, Saurman etc), while good rulers fight actually lead their underlings into battle (like Gandalf, Aragorn, and Theoden did).
 * Denethor isn't being cowardly, though. Before he goes insane from the use of Palantír he essentially tells that if everything is lost and Gondor falls, he will be spared so that Sauron can personally gloat and mock him, and then he will have a chance to strike personally, revealing that he's been living and even sleeping in a chain mail with sword on his belt to prepare for that moment. That is the reason he won't endanger himself in lesser battles. "Historically," Denethor is recorded by Tolkien as personally leading many defenses of Osgiliath, and every bit Boromir's equal in the pure badass department.
 * Somewhat undermined in the movies where the Eye of Sauron shows up plenty of times, such that the audience assumes (erroneously) that Sauron is the Eye.
 * Galbatorix, the Big Bad of the Inheritance Cycle, has yet to put in a physical appearance in the books. He does appear in The Film, played by John Malkovich, but this was only for appearances' sake.
 * Floyd Thursby, the murder victim in The Maltese Falcon.
 * The Patient in The Screwtape Letters.
 * Emmanuel Goldstein in Orwell's Nineteen Eighty-Four (sic).
 * Beatrice Baudelaire from Lemony Snicket's A Series of Unfortunate Events.
 * Altered Carbon includes the often-referenced but never-present Elias Ryker.
 * Bod from The Graveyard Book never sees the Sleer.
 * Matai Shang, Holy Hekkador of the Holy Therns in John Carter of Mars hovers around the edges of the second book, The Gods of Mars without ever putting in a direct appearance. He finally shows up in the next book, The Warlord of Mars, where he's half of the Big Bad Duumvirate.

Live Action TV

 * This trope fits the grossly oversized Stan (or so we are told) from Will and Grace to a tee.
 * His hand is seen in one episode, grabbing at Karen's breast.
 * In Scarecrow and Mrs. King, there was a character in the first season or two (later phased out) who drove around in a limo giving out orders/assignments. The name of the character was probably "Mr. Blue."
 * On Sports Night, Luther Sachs was the owner of Continental Corp, which owned Continental Sports Channel, which broadcast the titular Show Within a Show. Though there were many times he was referenced (through such things as people having to take a call from him or having to go meet him, etc.) he was never seen or heard.
 * In public-relations specials, these characters need not even be fictional. After playing The Voice (Carlton the doorman on Rhoda), Lorenzo Music (who also provided the voice for Garfield) later appeared on a Garfield TV special with his back to the camera at all times, as Garfield's creator Jim Davis remarked that he'd never seen his face. The producers of an E! special on Beanie Babies did something similar with the founder of the Ty corporation.
 * Bill Wilson, founder of Alcoholics Anonymous, and Gravity's Rainbow author Thomas Pynchon, both of whom refuse to appear on camera throughout their whole careers.
 * In his first interview after leaving the band in 1980, former KISS drummer Peter Criss appeared with his back to the camera, apparently at the insistence of his former band mates. At the time, KISS had never appeared in public without their trademark stage makeup. Criss would reveal his face in a television appearance later that year. The band would abandon its makeup in 1983 in an "unmasking" on MTV.
 * Similar to the first example, VH-1's I Love The 90s had a segment on MovieFone, with the celebrities commenting that they had no idea what "Mr. MovieFone" looked like. They actually had the actor, Russ Leatherman, on the show.
 * Linderman of Heroes was this for much of the show's run, often referenced with characters seen speaking to him over the phone, or middle men conveying his orders. This makes sense as he's very much the shadowy manipulator but it was actually because the show couldn't afford to have a big star like Malcolm McDowell appear in too many episodes.
 * This makes it even more strange to see a kind, grandfatherly character as the Big Bad, while we have been assured that "Mr. Linderman" is a truly ruthless, merciless villain. Informed Ability anyone?
 * Except that he really is an evil manipulator, so he's closer to Affably Evil.
 * Moonlighting characters often referred to the "Ensalmo Case," which sort of combines this with Noodle Incident: The case was only mentioned in passing. There were no characters named Ensalmo, nor did the case ever come to a close.
 * It's revealed in the Grand Finale that it was never solved.
 * During several episodes of My So-Called Life, Rayanne Graff mentions a friend named "Tino" who never made a physical appearance throughout the show's unfortunately short run.
 * And, of course, the ultimate example, Charlie, from Charlie's Angels. He usually appears as The Voice, but has sometimes appeared as The Faceless in several episodes and only finally reveals himself to the Angels.
 * Chef in Star Trek: Enterprise. In the last episode, he's revealed to be... William Riker? Actually, Riker was on the holodeck playing Chef.
 * Captain Boday in Star Trek: Deep Space Nine. He was said to have various strange features, such as a brain visible through his transparent cranium.
 * The banker on game show Deal or No Deal. His body can be seen from the booth, but there is no lighting on him, making him practically a shadow.
 * Norm's wife Vera in Cheers, although she was occasionally given a voice or partially shown.
 * Also Sam's brother Derrick, although he was given a voice.
 * Maris of Frasier. The creators had initially planned to show her, but the descriptions of her made her so monstrous that after a few seasons, they couldn't think of a way to show her without underselling the character.
 * Also the source of a hilarious subplot involving Niles getting a pet whippet that everyone agrees is basically a canine Maris -- this is basically the closest the audience ever gets to seeing the woman.
 * Except that we did see a heavily bandaged-up Maris in a flashback in one episode set in a hospital, but it was brief and she was almost entirely covered up. Another episode showed us her silhouette against a shower curtain.
 * Arthur Daley's wife in Minder, fearfully referred to as "'Er Indoors."
 * Mrs. Columbo.
 * Lars Lindstrom, Phyllis' husband on The Mary Tyler Moore Show.
 * As noted, Carlton the doorman in the spin off, Rhoda.
 * Don Pardo announced the prizes on many game shows, and the cast on Saturday Night Live during the '70s, without ever appearing on-camera. One SNL skit lampshaded this by having Pardo appear as, literally, an invisible man; auditioning for the SNL announcer gig ("Don Pardo? Is he still alive?"), his invisible presence sits down in a swivel chair which visibly moves and audibly creaks.
 * Subverted on the NBC episodes of The Price Is Right, as he would occasionally be seen on camera as a substitute host whenever regular host Bill Cullen was either sick or on vacation.
 * On Lost, the "monster" was unseen for the whole first season.
 * Subverted:
 * Seinfeld had several, most notably George's Boss George Steinbrenner, whose face is never seen, Kramer's never-seen friends Bob Sacamano and Lomez, and Jerry's cousin Jeffrey, about whom Uncle Leo talks constantly.
 * "This is Dr. Kahn..." from Salute Your Shorts.
 * In Twin Peaks, Agent Cooper constantly recorded messages to "Diane" with his mini recorder, but Diane herself is never seen or heard. She does apparently mail Coop some earplugs at one point, however, so she is assumed to actually exist.
 * In The X-Files, Mulder often made calls to someone at the FBI named "Danny," requesting warrants, paperwork, or other small but difficult-to-retrieve items they needed in the field. Sometimes Scully called Danny, and once John Dogget did as well. However, audiences never got to see Danny. The closest Chris Carter ever got to a character description was once during an interview when he joked that Danny was a gnome that lived in Mulder's desk.
 * The extent to which Burnside is/is not willing to reconcile with his ex-wife Belinda in The Sandbaggers is a plot point in several episodes. However, she is never seen.
 * Dan & Becs is absolutely made of this trope. Although the only characters to appear onscreen are the titular ones recording their video diaries, between them they reference dozens of characters. Just for starters: their respective parents, Becs's sister, their various respective friends, their various respective friends' siblings, Becs's agent, Dan's various exes, the various people they meet when looking for work... the list goes on. And that's not even starting on the real-life people who are unseen characters within the show.
 * On The Andy Griffith Show, Goober started out as one of these; his cousin Gomer would tell Andy, "Goober says 'hey,'" when the two men met. Goober finally made an appearance (alongside Gomer) in the season 4 episode "Fun Girls," and after Gomer left for his own show Goober essentially became his Suspiciously Similar Substitute.
 * Sarah, the town telephone operator.
 * Then, of course, there was "Juanita," the waitress that Barney sometimes flirted with on the telephone.
 * Mash: Sparky, the radio operator at I-Corps who Radar or Klinger often speaks with, pretty much fits this trope... although he did make a single, brief appearance in the season 1 episode "Tuttle."
 * The camp's P.A. announcer was both this and The Voice.
 * The characters' loved ones back in the States, obviously...although some of them did "appear" via home movie, including Henry's wife Larraine, Frank's wife Louise, B.J.'s wife Peg, and Radar's mother (played by Gary Burghoff in drag).
 * B.J.'s wife Peg appears again in the surreal episode "Dreams", in a depressing Nightmare Sequence that is meant to show how much he misses her and how he believes the war has pulled him away from her. Naturally, everyone else is suffering a case of this throughout this particular episode.
 * In the "Run for the Money" episode, Charles gets a tape recording from his sister Honoria, so we get to hear her voice (which includes a bad stutter).
 * Colonel Potter's wife in the states, Mildred, does not appear in the main series (save as a photograph on his desk), but is a regular character (played by two different actresses) in the short-lived spin-off After MASH.
 * The physical incarnation of this particular trope is undoubtedly Wilson from Home Improvement. If it wasn't the fence hiding his mouth, it was a tree branch, a grill, other people, a Santa beard, or even a yam!
 * Also, Al's mother.
 * Wilson's mother.
 * The main character's father in Captain Nice.
 * Bernie "the bolt" on The Golden Shot.
 * Nils' mother Elna in the first season of Norwegian sitcom Mot I Brøstet, only referred to and heard through one-sided phone calls for the first 7 episodes. The sequel series Karl&Co did the same with Ulf's wife Magda, who stayed unrevealed throughout the entire series.
 * Howard Wolowitz's mother on The Big Bang Theory is never seen, but her voice is constantly ringing out around his home.
 * Captain Mainwaring's wife Elizabeth from Dads Army, who is apparently much scarier than the Nazis. We get the briefest of glimpses in one episode where the two are lying in bunks, with the captain on the bottom. Above him in the top bunk is an extraordinarily massive indentation, suggesting a literal mountain of a woman.
 * Peggy's mother in Married... with Children. She is implied to be amazingly obese, so perhaps the idea is that the camera couldn't have fit her in?
 * In Keeping Up Appearances, Violet was this for the earlier series. She eventually made her full-time appearance as a character later in the run.
 * Sheridan was this for the whole series.
 * Amber, daughter of Tim and Daisy's landlady Marsha in Spaced. The others hear her having raging (but indistinct) rows with her mother, and at one point she storms downs the stairs played by the producer's sister in a wig, but neither they nor we ever meet her or see her face.
 * Robin Masters, the author who owns the estate on Magnum, P.I..
 * The Cosby Show: Kenny's chauvinist older brother.
 * The Inquizitor on Inquizition.
 * Kim's "best friend" Tina on Kath&Kim never seems to spend any time with Kim at all.
 * Angela Valentine was a girl in Beaver's class at Grant Avenue Elementary School in Leave It to Beaver. She was mentioned in no fewer than 16 episodes throughout the series' run. Usually concerning her sixth toe or getting sick in class, having a real gold filling, the eating of library paste, winning a tool chest at the local theater, suggesting (and then winning) a class beauty contest, losing her bike plate on the playground, bringing a "baked Alaskan" to the cake sale, getting her extra toe cut off, calling Beaver a "dirty, rotten, smelly old apple," having a birthday party, getting sick in the back of the school bus and wearing a Jackie Kennedy wig to school. (She is shown very briefly in 2 episodes but only from behind and later running or walking by. No one seems to know who played the part.)
 * Martha's often talked about boyfriend Chet is never seen on screen.
 * Friends has "Ugly Naked Guy" who is blessedly always off-camera.
 * The only time "Ugly Naked Guy" appeared on-screen, he was shot from the back (and thankfully above the waist).
 * First boss Mr. Bell in The Drew Carey Show. His voice is frequently heard over intercom, but he doesn't appear on-screen until the end of the first season (in which he's been fired).
 * The documentary film crews from all the various versions of The Office, who never speak or overtly involve themselves with the office workers, but who must have some offscreen relationship with them, especially in the long-lasting American version.
 * Red's wife Berince on The Red Green Show was never seen (except in a Christmas special near the series end).
 * Dalton's wife Ann Marie also went unseen for most of the show, but was later upgraded to The Voice.
 * Actually, the show was full of these people. There were a number of lodge members who were always talked about but never seen, mainly Moose Thompson and Old Man Segewick.
 * For that matter there were often entire episodes in which unseen characters would have significant roles.
 * The Royle Family, which rarely leaves the confines of one house, creates a whole community of characters only ever described by the core cast. Chiefly; Jim and Barbara's neighbour 'Leggings' Lorraine, the housebound Elsie (who lives in the same flats as 'Nana' Norma and whose eventual death provides the background to an episode in the third series) and Dave's best friends Tony Macca and Gary. Most memorable though is Tony's supposedly tarty - and well-endowed - younger sister, Beverley.
 * Some characters are talked about in several episodes before we do eventually get a glimpse of them, including Anthony's best friend Darren and girlfriend Emma (plus her parents). Dave's parents were also regularly mentioned but didn't appear onscreen until the 2008 Christmas special. In addition, crucial aspects of Norma's character are introduced in the very first episode, when she makes a phone call to the Royle household, but it's not until later in the series that we see and hear her.
 * Adele, Sherrif Metzger's wife in Murder, She Wrote is often mentioned but never seen.
 * Kimmy Gibbler's parents from Full House is regularly mentioned by Kimmy, but is never shown onscreen.
 * Felix’s ex-wife Gloria did not appear until the second season of The Odd Couple.
 * Oscar’s girlfriend “Crazy Rhoda Zimmerman” was never seen.
 * John Bracken, studio head and title character of Brackens World, was not seen until season two.
 * Caroline's father, Martin, in Two Broke Girls. Justified since he's in jail, but both she and Max have been shown talking to him on her phone.
 * Cambot in Mystery Science Theater 3000, apart from his brief appearences in the Robot Roll Call. Justified in that everything on the Satellite of Love is seen through his lens.
 * Until the last season Morty Fine, Fran's father, from The Nanny.

Newspaper Comics

 * In Peanuts adults were seen exactly once: Some adults were partially shown in an early strip depicting Charlie Brown and Lucy at a golf tournament.
 * In a few early strips Linus and Lucy's parents (and blanket-hating grandmother) can be "heard" off-panel, and the kids' schoolteachers are heard (albeit as trombone music) in the animated specials.
 * The Little Red-Haired Girl is also never seen, except once in silhouette. (She is seen in one of the specials, It's Your First Kiss, Charlie Brown, although this was deemed non-canonical by Charles Schulz.)
 * Also Snoopy's nemesis, The Cat Next Door.
 * Susies' parents in Calvin and Hobbes. Their voices were heard from off-panel once or twice, but they never appeared.
 * Susie's mom was seen from the waist down once.
 * The Phantom is usually wearing a mask or sunglasses; whenever he's not, he's usually shown from behind or has his head out of frame. In-story, anyone who sees his face will die (mainly through Laser-Guided Karma), but his wife and other loved ones are apparently excluded. (In one ancestor story, the current Phantom had died and his son arrived at the Skull Cave to take up the role; he's shown completely, face and all, for several frames. Presumably the curse doesn't take full effect before he dons the suit for the first time, or the comic's readership may have taken a drastic drop in numbers...)
 * In Cul De Sac, Dil has a horde of unseen older brothers whose hobbies include building trebuchets.
 * The title characters in George Herriman's early 20th century strip The Family Upstairs. They live on the top floor of an apartment building and cause endless problems for the poor souls situated below them.
 * This also applied to the title characters in another early strip, Pom Momand's Keeping Up with the Joneses.

Pro Wrestling

 * On WWE Smackdown, Tazz frequently referred to a mystery bookmaker named Joey Numbers who gave him insider dirt on the wrestlers currently in the ring.
 * WWE Raw has an anonymous general manager who only communicates to whomever's in the arena via e-mails sent to Michael Cole.
 * Vince Russo was this at the beginning of his WCW tenure as "The Powers That Be," and vowed never to show his face. After he was fired and re-hired, he showed his face for the first time in WCW.

Puppet Shows

 * On Fraggle Rock, Doc's neighbor Ned Schimelfinny is never shown, and only one side of conversations are ever heard.
 * Scooter's uncle, the theater owner, was supposed to be this on The Muppet Show. He actually did appear in a couple of season 2 episodes, but the writers decided he was better kept unseen for the force of the gag.

Stand-up Comedy

 * One who really defies categorization is the character of Vern from any of the late comedian Jim Varney's Ernest routines since the action was always told in first-person fashion from Vern's perspective, allowing the audience to essentially be that character.
 * Sometimes Vern's hands were seen, such as when Ernest got his hands caught in the window and asks for help, and the audience sees Vern's hands simply closing the blinds.
 * The late Joyce Grenfell used to do the same thing, with the audience taking the perspective of Shirley, or half the guests at a cocktail party (with Grenfell playing all the other half), or a nursery school.
 * "George...don't do that."

Theater

 * Dorothy Gale in Wicked. She is only heard crying in Elphaba's dungeon, and seen in silhouette when she throws the bucket of water.
 * The unseen Mrs. Grundy, in Thomas Morton's Speed the Plough, in which Dame Ashfield continually worries, "What will Mrs. Grundy say?" of each development. Since then the term "Mrs. Grundy" has passed into everyday speech as the embodiment of prudery and censorship.
 * Nell from The Comedy of Errors, whose infamous breadth is probably better described than seen.
 * Wilson, the unseen boss of Gus and Ben in Harold Pinter's The Dumb Waiter. He may or may not be the one sending them mysterious messages via the titular device throughout.
 * Godot never does turn up.
 * Charlie and Myra in Neil Simon's Rumors. Charlie (the host) spends the entire play in his bedroom having shot himself through the earlobe for an unexplained reason, and his wife Myra reveals that she spent the entire evening locked in the basement in the play's final line.

Video Games

 * Many First-Person Shooters have no cutscenes or anything showing the protagonist, who therefore remains faceless and sometimes also unheard.
 * The original Doom made this famous - the only reason anybody knows what he looks like is the face in the status bar.
 * The ultimate example is Gordon Freeman of Half-Life, where we wouldn't even know what he looks like if not for the box. He shows up very briefly in the expansions, but then in Half-Life 2 he doesn't even have a model.
 * An odd example from the third Sly Cooper game: Jing King, the Panda King's daughter, is only ever seen as a silhouette behind a screen. No reason is ever given for this.
 * Sly's father, in games' flashback scenes, is only seen from the legs down.
 * Despite being clearly seen in Halo 2, is never seen beyond his tentacles in Halo 3, much to the annoyance of many fans.
 * It's arguable that we did see him. Some hints suggest that.
 * Mickey Mouse in the first Kingdom Hearts game is absent for most of it, leaving his castle to infiltrate Organization XIII and depending on his trusting aids Goofy and Donald to guide Sora. In the sequel.
 * Likewise, Sora's family is represented by a disembodied female voice, calling him for dinner.
 * Gary Smith is absent for the majority of the game Bully. Somuchso that
 * In Backyard Sports, Stephanie Morgan always talks about her best friend Dorothy, who is never seen in the game.
 * The Lich King is this for the core campaign of Warcraft III, despite being one of the main villains and having his backstory described in detail in the manual (though to be fair, he is sealed inside a block of ice, controlling his minions telepathically). He does show up in the expansion.
 * Until Wrath of the Lich King, this was a staple of most of World of Warcraft. The Big Bad was rarely seen other than his or her particular raid encounter. The Lich King, however, had a very prominent and personal role for the player all throughout Wrath of the Lich King, as does Deathwing in Cataclysm, so this seems to have changed.
 * In the games Betrayal at Krondor and Return to Krondor, there is a character called the Crawler. The Crawler is never seen or heard, only mentioned through conversations and letters. What is known for certain is that the Crawler is some sort of crime boss, and is assumed to be male. He has an agent named Bear, who is very dangerous on his own. He also has powerful connections (one letter from a powerful man in a land called Kesh warns his niece to "Beware the master of Durbin. The Crawler's plot is a web within a web."). It is too bad a game has not made where you actually get to fight this guy.
 * The protagonist in the game In the 1st Degree is prosecutor Sterling Granger. The character is male, and you can hear his voice. However, he is never seen in the game.

Web Comics

 * The Big Bad of Order of the Stick, Xykon, has a monster that he's keeping in the shadows for the final confrontation with the heroes. When they leave the dungeon, this shadow is provided by a pink Hello Kitty umbrella which, nonetheless, casts a pitch black shadow in which nothing but the monster's eyes can be seen. Even later the monster is placed in a box to preserve the surprise. Rich Burlew is well aware of this trope, and teases the readers by offering small displays of the creature's powers.
 * Solid Snake is sorta seen in the webcomic, The Last Days of Foxhound but only as a featureless silhouette.
 * By the time Gordon Freeman arrives in Concerned, you only get to see his arm (and weapon he's holding.) Sometimes he is in full view, but so far away you can't make out any detail.
 * In Blip, K's roommate is only shown in silhouette, and never named.
 * Old Cobbley, Sylvester's (possibly psychotic) homeless friend from ''A Game of Fools is mentioned in passing quite a bit, but yet to make an appearance.
 * Ssid in Bitmap World. Originally, he was not seen because he was hiding, however, after that storyline, the character is only shown as a pair of eyes under his desk. No explanation is given as to how he manages to get any work done. His first appearance.
 * In the webcomic Jix, the bounty hunter Maricax is never seen out of his armor, though at the end of his story arc, he is seen wrapped in bandages and some of his burned skin, one of his eyes and the tip of his nose can be seen as well as some green fur poking out of the bandages, but his face itself has never been seen.
 * Dragon City has a parody of Batman named Batdragon. His face has never been shown in the comic. This is because the comic isn't about him. This allows the reader to see him as the main characters do and none of them know his real identity.
 * Erfworld's Charlie, much like his real-world namesake, is never seen by anyone except a select few of his highest Archons. If he needs to send a Thinkagram to someone, he'll appear to them as a variety of whimsical symbols that either reflect how the conversation is going or what he thinks of whom he's speaking to.
 * Played with in Something Positive. Mike's son is shown occasionally, but his FACE never is. He's supposedly grotesquely ugly, but you have to take the characters' words for it.

Western Animation

 * In older MGM cartoons such as Tom and Jerry, humans are only shown from the legs down, with an occasional shaken finger for emphasis.
 * This rule is flipped 180 degrees by Crack Stuntman of Homestar Runner -- we never see below his waist.
 * Cow and Chicken parodied this one -- the (human) parents of the title characters didn't exist above their waist. This was only shown twice: in the pilot, and in an episode of I Am Weasel (its spinoff), "Who Rubbed Out Cow and Chicken?" However, their shadows turned up too, and photos of them were of their upside-down legs.
 * One episode played with this; Chicken, rummaging through the closet, pulls out what appear to be the upper halves of a man and a woman, possibly their parents. After a stunned second, Cow says it's from an old school project.
 * In the original Peanuts specials, adults were never seen (and only heard as "Mwah-wah" sounds, making them also The Unintelligible), although on at least one occasion the unseen teacher's hand was shown giving a paper to Peppermint Patty.
 * A few specials and one of the movies showed adults. The Little Red-Haired Girl occasionally put in an appearance, under various designs.
 * Dr. Claw from Inspector Gadget is never shown except in an over-the-shoulder shot of him sitting in a high-backed chair which obscures everything except his gloved right fist. This was played on in the opening, which had Gadget run in and handcuff him... only to reveal that he's really handcuffed a glove attached to a chair with a bomb in it.
 * The toy for Dr. Claw does reveal his face... and was a major letdown for many as a result.
 * In the cartoon Hey Arnold!, there is a character that Gerald refers as "Fuzzy Slippers" and who knows a lot about urban legends, the local guys and how to contact a superheroine, but Fuzzy Slippers is never seen.
 * There is also the boarding house resident Mr. Smith we never see him aside from his silhouette and hand and when they eat together he has Arnold send him his food through a dumbwaiter, one episode has the residents try to break into his apartment so they can see him but Arnold convinces them to respect his privacy after they see he has a photo of the residents whom he considers his family.
 * One of the stranger examples of this was in the episode "I Oughta Be in Toons" of the Disney series Bonkers, in which Mickey Mouse is the focal point of the plot (he is kidnapped by an impostor who attempts to sign a large contract with a rival studio) but is never actually shown on screen (except for a brief silhouette toward the beginning) or mentioned by name, only heard from inside the cage in which he had been locked.
 * Disney had a weird, unwritten policy in the '90s that actually putting Mickey Mouse in cartoons would somehow dilute his iconic marketability. The logic was that if anything he was in was ever regarded as bad, it might hurt the whole company, so it was better to never actually do anything with the character at all. A similar policy was instituted for the first Kingdom Hearts game. This weird policy was thankfully dropped in the 2000s, probably because people began to question just what the hell he actually did besides pose for merchandise.
 * XANA from Code Lyoko. As an artificial intelligence, he solely exists as a program inside supercomputers. Hence he never takes a visible form, but his influence is certainly felt, symbolized by the ever-present "Eye of XANA" logo.
 * This is arguable as XANA at one point does appear physically, but takes on Jeremy's appearance. It's debatable that XANA also appears in the form of a black shadow with the logo on it.
 * The nanny from Muppet Babies is usually only ever seen from the waist down; we never see her face. In a time travel episode we see her whole body but she is bent over while talking to someone in a car so her face is obscured.
 * In Doug, Principal Buttsavitch was mentioned but never shown. In the "Doug Graduates" (part of the last episode before Disney took over the show, not counting the Christmas special), Doug and Roger actively searched for him so that they could get some words of reassurance, since they were nervous about graduating, but they never actually found him. Also, Skunky Beaumont was a character who was often mentioned but never seen. He appeared in Disney's Doug, and he is portrayed as practically an Expy of Jeff Spicoli from Fast Times at Ridgemont High.
 * Rocko's next-door neighbor/unattainable unrequited crush Melba Toast on Rocko's Modern Life. We only see an arm here or a leg there, and she is never seen at all, only mentioned, after the first season (rather cleverly, the comic book played off of the lack of information about Melba in one issue by having her be a successful model... of products which only require the hand or foot to be displayed).
 * Most of the characters' parents in Tiny Toon Adventures were like this; if they were shown at all, it was from the waist down. The notable exceptions were Hamton's parents (seen in The Movie), Elmyra's entire family, Calamity Coyote's dad, and Plucky's dad.
 * In the first two seasons of Rugrats, Chuckie's mom was presumed to be alive, and would be referenced periodically. It wasn't until the Mother's Day episode that she was finally seen, and the revelation came that she was dead.
 * In The Weekenders, Chloe Montez is commonly discussed yet never seen.
 * Fire Lord Ozai from Avatar: The Last Airbender isn't shown for the first two seasons. Most of the time he was a shadow behind a curtain or too far to be seen in details, or only his back or legs are shown.

 * Gazpacho in Chowder often talks about his mom but she has yet to make an appearance.
 * Eddy in Ed, Edd 'n' Eddy often spoke highly of his brother, who never appeared
 * Also adults in general they sometimes mention their parents and talk to them but we never see them except in one episode where we see Ed and Eddy's parents' hands drag them away over bad report cards, in the episodes where they're in school the teachers and faculty are also unseen.
 * Thumper's mother, from the Bambi duology, constantly refers to his father's Green Aesops whenever Thumper is causing her trouble, even though he is never once seen onscreen or even heard in either movie.
 * Mickey's father the King, from Mickey's The Prince and the Pauper, is never fully shown; even during his death scene only his hands and silhouette are seen.
 * Beavis and Butthead's moms -- they occasionally mention them and sometimes call to them but they are never seen.
 * The User in Re Boot. The closest we ever get to seeing the human operating Mainframe is a computer screen when the restarts the system.

Real Life

 * Muhammad. Muslims have repeatedly threatened violence and murder when Muhammad is pictured in any way.
 * It's worth noting that this wasn't always the case. This page is a good starting point for understanding this.
 * It's still a matter of contest among different branches of Muslim faith. Until only a few years ago pictures of Mohammed were perfectly common in many Islamic countries.
 * Anonymous
 * Any Strawman Political ideal. An Unnamed Democrat/Republican for example -- a very popular choice in the polls for any election, because he/she has no opinions, and therefore has no unpopular opinions.
 * Karl Albrecht, one of the 10 richest people in the world, is a complete mystery to the public. What is commonly known about him and his brother is that they took over their mothers convencience store and created a business empire with a discount store chain. There is one known photograph of his brother Theo, who also was a billionaire, which was taken in 1971.
