A Form You Are Comfortable With



"Joan: Are you -- Are you being snippy with me? God is snippy. God: Let me explain something to you, Joan. It goes like this: I don't look like this. I don't look like anything you'd recognize. You can't see me. I don't sound like this, I don't sound like anything you'd recognize. You see, I'm beyond your experience. I take this form because you're comfortable with it, it makes sense to you. And if I'm "snippy", it's because you understand snippy."

- Joan of Arcadia

Sometimes, when God or some other vastly powerful or very strange Cosmic Entity needs to have a chat with a mere human being, they are aware that the meeting might be a little too overwhelming for the human to handle. Sometimes the nonhuman being isn't so powerful, but still has a Masquerade to maintain. Or they fear having to deal with hours of questions and a great deal of prejudices. Humans tend to flip out when they see a dragon or learn that Fairies are real.

In many cases, the nonhuman being will appear in the form of something, usually a humanlike form, that the human can wrap his head around. Because let's face it. Not doing so might ruin the point of the entity talking to the humans in the first place.

Of course, the real reason for this trope is that it is easier (and cheaper) to cast Morgan Freeman as God than it is to figure out what God really looks like. For added effect, the Cosmic Entity may also rearrange the local environment into a place the human is comfortable in, just to be extra accommodating.

This is a common practice among Sufficiently Advanced Aliens, along with Translator Microbes, to allow full communication. Compare how Heaven tends to be this way for observers/visitors. See also You Cannot Grasp the True Form. There is also some crossover with Shapeshifter Default Form. Humanoid Abomination is an unintentional example, and even then things can be a bit... off.

Relates to Lies to Children, especially if the form taken is in some way representative or symbolic of the thing's true nature. Contrast They Look Like Us Now.

Anime and Manga

 * In The End of Evangelion there are millions of supernatural Rei clones that, as a part of the Instrumentality, take the shape of a person's loved one or a close friend, and then hug them. It's a trap to make the humans lower their ATF and allow the clones to touch and remove their soul, reverting humanity into souls and LCL.
 * Or, if the person is too scared/doesn't believe that it really is their loved one, just goes ahead and turns them into LCL by force.
 * And then there's
 * Aoba, however, experienced only a multitude of naked Reis, implying there was no one he truly loved.
 * In Baccano!!, the demon summoned aboard the Advenna Avis has taken to adopting a human form (which can be recognized as one of the supporting Camorra gangsters, Ronnie Sukiart). His true form is never shown in the anime, but the Light Novels imply that it's rather disturbing.
 * Of course this shows up in The Melancholy Of Haruhi Suzumiya, since the Data Overmind is of an existence completely alien to physical humanity, yet wants to discover what makes the title character able to do what she does; it has constructed humanoid Agents who can observe and interact. These Agents are partially their own being, partially of the Overmind.
 * How exactly individual Yuki is in comparison to the Overmind is a common theme in the series; however, definitely of this trope is Kuyou Suou, an agent of the competing faction the "Sky Canopy Domain". She has no individuality at all (at least according to Kyon); she's entirely a humanlike mouthpiece for the Domain. This doesn't quite make Kyon feel more comfortable, though, because Kuyou's horrible social skills (being unable to even talk coherently or look normal/visible) make the plan for them a failure in that respect.
 * In Hellsing Alucard, due to the thousands of souls inside him causing a lack of a definite gender, can change his appearance at will. To quote the man himself, "Form means nothing to me."
 * The wolves of Wolf's Rain spend most of their time as humans, even when they should be in wolf form (for example, when humans are no where to be seen,or when they ate a dead deer). Presumably this was because Most Animators Are Human and it was just easier to have their human forms be on screen.
 * This is most likely a device to reinforce the fact that the "human form" seen by the world and the viewer is really an illusion. Very often, when the plot doesn't force the viewer to see them in a specific way (as people in the presence of people, for example), the viewer sees them switch back and forth: often very quickly from cut to cut.
 * Sebastian of Black Butler is strongly implied to have no form he's truly comfortable with, not even his own demon form, and simply chooses this human form for the sake of Ciel. That, or Sebastian just likes the clothes.
 * In The Visitor, a one-shot manga by Kanno Miyamoto, a Shinigami explains that when visiting humans, he takes a form that would be comforting to that person. When he checks a file and sees that the dying man is gay, he notes: "That explains why I appeared as a man." So in this version, the Shinigami apparently have no control over which form they initially take.
 * Cerberus/Kero and Yue in Cardcaptor Sakura/Cardcaptors. At first they sleep mode as a stuffed animal and ordinary human but even after recovering their true forms they don't use them much. Probably because a large flying lion with some kind of helmet and a rather scary blueish angel would freak people out. The main cast, however, doesn't care.
 * It serves a practical function as well, particularly in the case of Yue. Their true forms constantly emit magic (since both are the products of magic), which becomes dangerous if prolonged. This becomes a plot point in the "Sakura Cards" arc when a magic field prevents both of them from returning to their "borrowed forms" and Sakura has to come up with a solution.
 * Technically, Envy from Fullmetal Alchemist would count. He is a shapeshifter, and...well, his true form isn't exactly beautiful. Although in his case, it's because he is envious of humans, rather than wanting them to be comfortable.
 * And Truth takes this trope a step beyond: it literally wears YOUR body parts. So...a form you are uncomfortable with?
 * In Inuyasha, Youkai of particularly high level can turn into a completely human form. It also makes it easier to wield a sword.
 * Shinigami in Soul Eater is in appearance a Lighter and Softer version of your classic Grim Reaper-type being. He states at one point he took on this look (and associated Cloudcuckoolander persona) in order to recruit children to his school, as his true form kept scaring them away. When he loses said persona and look it's an indication he's either truly angry or simply tired of his staff mucking around and puts on the scary voice to shut them up. Possibly a difference in perspective/art, but his size also seems to vary. At times he can look imposingly tall, far more than a human would be, at others he appears not much taller than his Weapon Spirit (who is tall, but not that tall).
 * Holo of Spice and Wolf is a wolf deity, and over 500 years old, but takes the form of a young girl. She says that the human guise isn't uncomfortable, but her real reason is because she's afraid of frightening off Lawrence. This very nearly happens anyway, as Holo is forced to turn wolf to protect an injured Lawrence. Lawrence reacts badly to being approached by a giant wolf, which in turn only alienates Holo further. Lawrence comes to his senses quickly, though, and manages to salvage the relationship. From then on, Lawrence seems comfortable with both forms, having learned that Holo is the same regardless of appearance.
 * It's predictable that demons in Ah! My Goddess are actually monstrous, but it's revealed at the same time that even Belldandy isn't as human as she normally appears. Keiichi decides he doesn't care.
 * Its the reason why the Scab Coral created human from Coralians to interact with humanity in Eureka Seven.
 * The Lord of Nightmares from Slayers can pick any form she wants, being god and all. She prefers to appear as a slender blonde woman though...at least, when she's not inside someone else's body.
 * Nyarlko chooses to look like a cute girl to appeal to Mahiro. But Mahiro is very Genre Savvy and versed in Lovecraft, and doesn't return her affection in part because of her 99 other insanity-inducing forms that he would not be comfortable with.

Comic Books
"Marco Polo: Are you always so pale? Dream: That depends on who's watching."
 * Happens all the time in The Sandman series. When done by Dream:
 * When appearing to his lover Nada, Morpheus himself takes on the form of an tall, African man covered in tribal markings. He did a very smooth statuesque thing with Augustus Caesar, and got mistaken for Apollo, about which he was rather snippy. Morpheus and the other Endless have a different appearance to each person that looks at them (the one we see seems to be the default British/American Caucasian version, though the art style shifts all the time because different artists came in for different chapters.)

"Jemmy: Nobody clever bes boxes!"
 * Dream also appears as a black cat to cats, black fox for foxes and a blackened face inside a fire vortex to the Martian Manhunter. The conceit is that people see the Endless as being either like themselves or like what they expect.
 * Dream seems to go back and forth with this: half the time he wears period clothing, but he sometimes shows up in the human world wearing ridiculous capes and things, which have drawn comments from humans who run into him.
 * John Constantine complained about the Robe of Flames being embarrassing, so he put on a black trench coat. John then complained about no sense of humor.
 * When done by others:
 * During the Season Of Mists storyline, Lord Kilderkin of Order manifests himself as the supreme icon of order - an empty cardboard box.
 * Likewise, the Chaos Lord called Shivering Jemmy of the Nightmare Brigade manifests as a three year old girl, complete with a balloon and a love of ice cream.


 * The above two are amusing because they did this to come to a convocation of gods and other powerful supernatural entities in the Dream realm, and there was no one to set at ease; they apparently just find these forms appropriate.
 * Gilbert, a rotund and helpful middle-aged man, was a manifestation of Fiddler's Green, an intelligent place that inhabited the dream realm.
 * Also, he looks very much like G. K. Chesterton. And talks like him.
 * Cain And Abel also qualify. It's heavily implied in A Parliament of Rooks that they weren't the first Human murderer and victim, but in fact the first murderer and victim in the entire history of the universe and their true forms are actually Starfish Aliens. Also, they aren't really related to Eve, who may or may not have ever been a real person to begin with, let alone whether or not she was really Human.
 * Invoked when Delirium actually mistakes a goth-dressed (lesbian) human for her sister Death in the beginning of Brief Lives. (Of course, it's unlikely any of the other Endless would mistake a human for one of their own, but Delirium and reality are not always on speaking terms.)
 * Lampshaded when Orpheus pays an unexpected visit to Death in Fables And Reflections catching her dressed down. She changes her twentieth century apartment, complete with a teddy bear, a fish-bowl and discarded stockings followed by a t-shirt and jeans clad Death, and replaced it with stone columns, eternal gloom and Death in a black Gorgeous Period Dress and a veil.
 * In the Lucifer comics God appeared to Elaine in the form of her loved ones at first, and when Elaine told him to be someone she didn't know chose to appear as an elderly British gentleman in a bowler hat. He appears content to stay in this form for the rest of the comic after that, something Lucifer comments upon.
 * The "out of continuity but very much inspired" Murder Mysteries had God disguised as a strange wingless angel, which the protagonist comments had eyes that seemed to contain more than the others as one of the first hints to his real identity. Oddly enough, once revealed as being God himself he is never shown in panel, despite no evidence of any transformation taking place.


 * The Martian Manhunter, Shape Shifter extraordinaire, avoids using his "true" martian appearance to avoid frightening people.
 * Galactus and other Marvel Comics "higher plane of existence" beings look humanoid to us, but that's just our filter.
 * Most of them "wear" temporary bodies when visiting the material universe, made to order for them by a being called Antropomorpho. Note that despite this trope, they're almost always shown in the same individual forms.
 * Galactus, however, doesn't have such a temporary body. Instead, his own form looks different to different viewers; for instance, a Skrull sees him as Skrull-like. (Galactus's original form as a mortal being in the universe preceding our own, however, was indeed humanoid.)
 * One issue featured a scene where humans and dozens of aliens gazed upon him at once, the frame was filled with smaller images representing what each of them saw him as.
 * Speaking of Skrulls, this is inverted by the cosmic Reality Warper the Shaper of Worlds, as the form he usually takes, a Skrull with silvery skin and a robotic lower body, is a form he is comfortable with, as he is an evolved form of a Cosmic Cube built by a Skrull and most of his owners before he evolved were also Skrulls.
 * Inverted intentionally by Doctor Strange foe Shuma-Gorath, who invades dimensions in whatever form will terrify the inhabitants most. On Earth he appears as a single glaring eyeball surrounded by tentacles.
 * Played straight with the Vishanti, who take vaguely human or animal visages to avoid terrifying their worshipers.
 * One time travel adventure for Tom Strong sees him encounter one his recurring enemies, The Pangean, who generally takes the form of a giant slime mold (who at this point, is roughly the size of a small country). Reasoning that Tom would rather speak to a biped, he splits off a part of his biomass, forming it into a shape resembling a green man wearing 17th century style clothing so that they can communicate more easily.
 * Implied by Whatever Happened to the Man of Tomorrow? as the reason for the fifth-dimensional trickster Mr. Mxyzptlk's usual form as a little man in a purple suit, when he mocks the characters for thinking that's what he actually looks like. Narrating the story years later, Lois Lane describes being confronted with his true, hyper-spatial form: "I can't describe what Mxyzptlk then became. He had height, width, depth... and a couple of other things". Within the comic, he's drawn as a gigantic energy being.
 * Lampshaded and justified by Cross Gen when Ilhan of Meridian visits Ingra of The First. Ilhan balks at her Stripperiffic default outfit, and Ingra amusedly transforms it into a more modest beige gown for his comfort, taunting him as she does so.
 * Variation: In Proposition Player, Bill the Angel of The Lord claims he uses that name because were he to speak his real name, the sky would rupture, the oceans turn to blood, a thousand virgins die, etc, etc. Given that he's basically a bully and leg-breaker for the forces of Heaven, it's not certain whether he's sincere or just being an egocentric jerk.
 * In one issue of Fantomas, the thief/hero tries to steal a unique duck-billed dog. It turned out to be an alien sent to Earth to study humanity, who tried to take the form of a dog to go unnoticed, but something went wrong with the process. At the end of the story it changes into an Eagle instead, this time more successfully.
 * In Ultimate Marvel continuity, the Kree aren't the Humanoid Aliens of the regular Marvel Universe, but are Starfish Aliens. Pluskommander Geheneris Hala´son Mahr Vehl (Ultimate Captain Mar-Vell) takes a humanoid form to talk to SHIELD.
 * In Powers, the aliens who direct the Millennium Corps appear to Walker in human forms, most commonly those of Zora and Retro Girl. A subversion in that Walker has made it clear that he is not comfortable with them taking on the shapes of his dead friends and lovers.
 * Hellblazer; John's original dealing with his long-term enemy Nergal dealt with this. His summoning demanded Nergal appear in a form pleasing to the human senses. So Nergal took over the body of a little girl. Then it got worse.
 * In Runaways, Xavin deliberately shapeshifts into the form of a human teenage boy when he first meets Karoline, believing that it's something that she'd be comfortable with. When she's shocked by his appearance, s/he figures that her parents prepped her for him/her arriving in his/her natural Skrull form (really, she's surprised at the fact that her parents promised her hand in marriage to him/her). When Karoline reveals that she's a lesbian, Xavin takes the form of a human teenage woman, a form which s/he stays in most of the time when around Karoline. For the few times when Xavin thinks it's more helpful to be in a male form, Karolina of course does not interact romantically with him/her ("If you were a girl right now, I'd kiss you.")
 * God, in Lenny Henry and the Quest for the Big Woof, appears as a slightly geeky white guy, in green-tinted glasses and Joseph's dreamcoat. When Lenny questions this he says he could manifest an explosion of white light, but "Who'd want to sit behind this at the cinema?"
 * PS238 has lords of Order and Chaos, and to somewhat lesser extent their minions.

Fan Works
"“So what do you two really look like?” Ringo asked again. “Not as pretty as you guys,” said Varx. Shag elbowed him. “Shut up, Varx! We're not human, Ringo. We'd show you, but we don't have the ability here. This is a preset background with limited variability, so we're stuck with these avatars. But we're kind of... um....” “Kinda lizardy, kinda birdy,” Varx said helpfully. “With claws,” said George. “Yeah.”"
 * In Aeon Natum Engel, thanks to the Cthulhu Tech legacy, there are variable auto-censors that automatically render images (in real time) in ways that are deemed to be less harmful to the human psyche. The most common appears to make video look like something from an anime.
 * Some Naruto fanfiction show the various bijuu choosing to assume human forms in order to communicate with their containers. Whether the bijuu are more sociable or not varies from author to author, but the Kyuubi almost invariably ends up being a redheaded woman with a model's body.
 * Following Kyuubi appearing female, cue standard speech about "You think a female can't be strong?" from the demon. The fact that bijuu are living masses of chakra with no actual physical form, and thus no gender, is conveniently ignored.
 * Played with in With Strings Attached. The Fans look like featureless human mannikins to the four, but that's because they're stuck using standard humanoid telepathic avatars; they aren't especially worried about what the four might think of their real forms.


 * In The 10 Doctors, say that their appearances change with the needs of their desired champions. In the story proper, they manifest as attractive humanoid women in order to toy with the Tenth Doctor's need for meaningful companionship, and in a flashback,  manifests to Davros as a military officer.

Film
""Human beings have neither the aural nor the psychological capacity to withstand the awesome power of God's true voice. Were you to hear it, your mind would cave in and your heart would explode within your chest. We went through five Adams before we figured that one out.""
 * In Oh, God!, God (played by George Burns) specifically tells Jerry Landers that he could have appeared in any other form, but chose one that Jerry could understand. God does the same thing in the two sequels.
 * And both times, he looked like George Burns. So did The Devil.
 * One of the Sufficiently Advanced Aliens in Contact takes the form of Eleanore Arroway's dead father in order to be able to talk to her. The Caribbean beach upon which they hold said conversation is also an example of this trope.
 * Not just that beach. Everything she saw outside the capsule after entering the second wormhole was previously shown in the film, implying that she was in some kind of VR from that point until she was returned.
 * The alien's "unfocused" form implies that it's a tall Gray Alien, similar to the one in Close Encounters of the Third Kind.
 * In Bruce Almighty and its sequel, Evan Almighty, God first appears as a janitor, played by Morgan Freeman.
 * In Mr. Destiny, Fate itself manifests to Jim Belushi as a bartender who looks a lot like Michael Caine.
 * This trope is the entire point of the Metatron's existence in Dogma.

"Winston: I thought Gozer was a man. Egon: It's whatever it wants to be."
 * And this turns out to be important to the finale.
 * Terminator: Salvation has SkyNet take the form of Dr. Serena when she debriefs Marcus in his role as her Unwitting Pawn. To add extra creepiness to the "kindness", she offers to switch her appearance into that of John Connor or Kyle Reese... as she is having both killed mere floors below! Needless to say, this was not a successful persuasive tool. Oh, and her eyes turned red like a Terminator's do.
 * Likely in an homage to this trope's use in Star Trek, the Thermians in Galaxy Quest disguise themselves as humans when visiting Earth. Their native form looks more like a mollusk than a human. In one scene, the Thermians forget to put on their disguises when visiting the Show Within a Show's stars—causing the latter to be quite disturbed...
 * They also keep up the disguises when no humans are around, because their slavish devotion to the Galaxy Quest "historical documents" made them build the ship exactly as they saw it—i.e., with controls designed for human beings. In their true forms, they can't use their own ship!
 * The title character in Starman takes the form of Jenny Hayden's recently deceased husband for exactly this reason.
 * In the remake of The Day the Earth Stood Still Klaatu says that his true form would "only frighten [humans]".
 * The situational variant of this is used in 2001: A Space Odyssey. David Bowman travels through the Star Gate, which we presume is even more mind-blowing in the flesh, so to speak, and ends up... in a hotel room.
 * Not only that; in the novel, Dave notices that it's a bad rendition of a hotel room. It might look okay on the surface, but he quickly finds out that he can't open any drawers, the books are painted on the bookcase and all food and drink containers, such as cereal box and beer cans, are filled with some spicy, blue stuff that smells like macaroons. It's as if someone was trying to imitate a hotel room without understanding it. He finally finds out why when he turns on the TV and sees the same room in an old soap opera on the screen. The aliens had based the room on what they had learned from various earth broadcasts. But then again, it is the result of the trope being played as straight as possible. It never was the never the idea that Dave should take residence in the room; its function was merely to calm him by placing him in a familiar environment, in order to prepare him for his transformation into the Star Child.
 * In 2010: The Year We Make Contact, Dave, having ascended to a higher plane of existence in 2001, creates a holographic image of himself as a human in order to communicate with Dr. Heywood Floyd aboard the Discovery. The film version is something of a Mind Screw, as he changes appearance randomly throughout the encounter; this is explained in the novel as Bowman having poor recollection of being human.
 * The Monoliths themselves are often described as having a dimensional ratio of 1:4:9; or at least it does in dimensions that we can actually see. Dave Bowman heavily implies that every Monolith encountered is actually the same one and that despite appearing from several feet to several miles in length, it has only one size, "as large as necessary".
 * Santo vs La Invasion De Los Marcianos (Santo vs The Martian Invasion): The Martians are basically human-shaped to start with, but decide to run themselves through a transformation machine to get more human bodies. This meant they wouldn't have access to their Death Ray Third Eye while in human form ... but that's good, because now the scriptwriters don't have to try explaining why Santo doesn't get vaporized when he goes mano-a-mano with them. And being able to ditch the long blond wigs probably made life easier for the wrestlers playing Martians.
 * It Came from Outer Space (1953). The aliens can copy human form; naturally this only serves to freak out those humans they're trying to reassure about their peaceful intentions.
 * Inverted in Avatar, it's the humans who take on the form of aliens in an attempt to begin diplomatic negotiations with them while they plan to destroy the planet.
 * Inverting this trope was the main thrust of Cameron's original script, in which the Na'vi are Starfish Aliens. (Sully still falls in love with a Na'vi in his Avatar form.)
 * The avatars are still different from the Na'vi, being Na'vi/human hybrids. They have smaller eyes and ten fingers and ten toes (the Na'vi have eight of each). Presumably, this is because a human wouldn't know how to function with only four fingers on each hand.
 * Though they seem to have no problem getting used to the tail...
 * The recent Percy Jackson movie adaptation has Hades, whose style resembles Mick Jagger's. When Percy, Annabeth and Grover are a little bit surprised by his appearance, he shows them his true form - a big, flamy, talking flame - and changes right back. His looks aren't discussed any further.
 * The humanoid version is implied to be closer to his true form - the flamey-demon-shape was just a form he picked to make them un-comfortable.
 * This trope was weaponized in Dreamcatcher. The true form of the aliens is a massive, tripodal creature that can devour humans; knowing that this form will instigate aggressive reactions, they project a telepathic image of the traditional Gray alien into human minds, making them appear weak and near-human.
 * Gozer in Ghostbusters:


 * Zarkorr! The Invader has a man who is judged to be the median of human society, chosen to prove his species's worth by (somehow) defeating the titular monster. The one who relays this challenge to him takes on a form that is made to be "familiar and unthreatening". In the protagonist's words: a "tiny, teenage mall-tramp."
 * Similar to the example from Dreamcatcher, the aliens in Progeny project the Gray form to make the abduction ordeal more comfortable for humans. Their real form, as revealed part-way through the movie, is horrific, non-humanoid, and vaguely reptilian.
 * Used in Star Trek V the Final Frontier with the alien "God" on the planet Sha Ka Ri. Inverted when
 * Used up to a point in Bless the Child, where most of the demons and angels look like regular people until the climax of the movie.
 * It is revealed that the chairman of The Adjustment Bureau has met with every single living person at some point in their lives, each time with a different look and gender.
 * God in The Prince of Egypt manifests Himself as a burning bush.
 * There's some precedent for that in the novelization.

Literature
"McKie: And all we see here is this... this bit of nothing. Caleban: Not put something here. Self-I put something here and uncreate you. Mc Kie discontinues in presence of I-self. McKie: Do you hang that, Tuluk? Tuluk: Hang? Oh, yes. She seems to be saying that she can't make herself visible to us because that'd kill us. McKie: That's the way I read it."
 * HP Lovecraft's Old Ones avert this trope, as they can't be concerned with whether their appearance causes puny human minds to shatter like glass.
 * Nyarlathotep, however, does hide in the ever-so-subtle form of... an Egyptian Pharaoh. He also likes to fuck with people's heads by sticking to the bare minimum. The reason one of his masks is known as "the Black Man" isn't because it appears to have African features, but because its skin is pitch black.
 * Actually, he does not always appear dressed as a Pharaoh, in Nyarlathotep; he is described only as a swarthy man "of the race of the Pharaohs" - from Lovecraft's letter: Nyarlathotep was a kind of itinerant showman or lecturer who held forth in public halls and aroused widespread fear and discussion with his exhibitions. These exhibitions consisted of two parts — first, a horrible — possibly prophetic — cinema reel; and later some extraordinary experiments with scientific and electrical apparatus. 
 * ...In cameo appearances in Friendly Hostility, though, he has gone so far as to don a form reminiscent of Neil Gaiman with eyes of infinite space.
 * So, Dream?
 * The Mi-Go in "The Whisperer In Darkness" take a stab at this trope with the...materials they have at hand.
 * Near the end of CS Lewis' Perelandra, two eldila attempt to find a suitable form to take when they meet the king and queen of Perelandra. Good thing, too, as their first two attempts wouldn't have worked at all.
 * In particular, one of those forms is described as being a particular perception of the eldila in much the same way as suffering a concussion and seeing stars is a particular perception of a rock (i.e. one that has been thrown at your head).
 * C.S. Lewis also explores the idea in an interesting way in The Chronicles of Narnia. Aslan the talking lion isn't just a Crystal Dragon Jesus, he actually is Jesus. Or rather, on Earth, among humans, he went by that name and form, while in the Talking Animal world of Narnia, he manifests as a fellow talking animal.
 * Yet another C. S. Lewis example is in the finale of The Screwtape Letters. Screwtape is reaming Wormwood for, and in his beautifully goosebumps-inducing description of what it is like when humans encounter God after they die, one of the things he says is that God "wears the form of a man."
 * In a short story by Margaret Attenborough, when God visits Kitty Heaven (which is actually Human Hell) he takes the form of a white Persian.
 * Abstract example: Stanislaw Lem's Golem (an artificial intelligence of the 14th generation) is pure intellect and has no personality whatsoever. When it gives lectures at the M.I.T. for a while, it is forced to assume a personality (an eloquent and apodictical preacher) so the humans can at least begin to accept it as an interlocutor, even though both sides are perfectly aware of the pretense.
 * Humorously played with in a science fiction story (name sadly forgotten) where a dead human whose casket is launched into space is brought back to life by a group of aliens. The main character/narrator asks the alien why it looks so human-like, to which the alien gives the standard response. He asks to see its true form, and when the being complies, the narrator notes for the audience that he "wasn't sure which end to talk to."
 * The Ellimist takes the form of a girl known by the Animorphs when he humbly requests their help. As he also stops time along with this, Jake thinks to himself that it's not really all that humble. Most of the time, he appears to the Animorphs (and Elfangor, in the 80s) as an adult male, or a wrinkly elf-like creature (as seen on the cover of The Ellimist Chronicles). At the end of The Andalite Chronicles, Elfangor sees the Ellimist as he truly is: "An indescribable being of light and time and space."
 * When the Ellimist appears to Tobias in The Change, he appears as a mixture of birds. "I saw it flying toward me. It was a bird of prey. A raptor. Some undefinable shape, part falcon, part eagle, part hawk. It had a snow-white belly and reddish-brown back and a tail that spread to show a dusky rainbow of colors." When Tobias comments that this wasn't how the Ellimist looked the last time the Animorphs saw him, the Ellimist says that he chose a shape Tobias would identify with.
 * Near the end of Carl Sagan's novel Contact, the main character encounters an alien being that has taken the form of her long-dead father in an attempt to make the experience less frightening.
 * The other characters encounter something similar. One person sees his granddaughter. Another sees her long-dead husband. And the Chinese archaeologist sees Confucius.
 * Wheeler, an alien of some kind or other beyond human understanding in the books Signal To Noise and A Signal Shattered, by Eric S. Nylund takes on a sort of human form. He takes on the form of the protagonist, Jack, except for perhaps some odd little differences such as the spinning gears in his eyes.
 * Michael Scott Rohan's The Spiral Series does this twice to the protagonist. In Chase The Morning it's part of the Battle in the Center of the Mind with the Big Bad, and in Cloud Castles it's his interaction with the Big Good. Both times it's presented as a business deal in his office, since that's how his brain could best handle what was happening.
 * In Harry Potter and the Deathly Hallows, after being "killed" by Voldemort, Harry finds himself in an Afterlife Antechamber that looks like King's Cross Station. Dumbledore, who meets him there, is a bit surprised by the description, but says it's what he can cope with. When Harry asks if he has to go back, Dumbledore extends the metaphor: he could, if he wished, metaphorically catch a train. "Where would it take me?" "On."
 * Played with in a Judge Dredd spin-off novel, Wetworks by Dave Stone: An alien adopts the form of a certain famous cartoon character in an attempt to make the humans it deals with more comfortable; it doesn't really work, partly because seeing a cartoon character in the flesh is actually pretty discomforting, and partly because although the alien's shape has changed it neglected to do anything about the fact that it constantly emits a toxic gas.
 * Subverted in Solaris by Stanisław Lem, where a planet-sized alien intelligence spawns human replicants convincingly interacting with the protagonists, while the purpose of this phenomenon and the message, if any, behind it are a maddening enigma.
 * Isaac Asimov used this in a number of his short stories. Notably in "Buy Jupiter", where aliens who inhabited the coronas of stars (and thus existed at temperatures in the thousands of degrees) interacted with humans by projecting human forms to Earth. The humans are fully aware that they are talking to simulations.
 * Mirror Girl from Blind Lake adopts the image of little girl Tess in order to talk to humans.
 * In Neuromancer, Wintermute speaks to the main character through cyberspace and takes the forms of people from his past.
 * Parodied in John Dies at the End by David Wong. When traveling to another dimension, the inhabitants there greet them completely in the nude for fear of appearing otherwise would disturb the visitors. They couldn't be more wrong.
 * In Otherland Jongleur tries to force this on The Other through the use of computer simulations. However, it's alien enough and has enough control that the simulation always warps into something disturbing. It may be telling that he ends up preferring to communicate with it as Anubis, while it whispers to him from a coffin.
 * The angels in His Dark Materials have a true form which is apparently something like architecture, but humans and panserbjørne (and others) see them as Winged Humanoids because their mind just can't wrap itself around their true forms. Technically, the angels aren't even taking this form, the mind of the observer just interprets them as looking like angels. This even applies to witches, who have much more expanded minds than other races and were aware of things like parallel universes long before them.
 * Explored extensively in C.S. Friedman's The Madness Season. The forbearer-type aliens called Saudar went to immense efforts to tame and enslave the inherently formless beings known as the Mara, who could not only adapt themselves to any shape, but could analyze the brain of the shape they took to immediately become fluent in spoken language, body language, and given enough time, social and cultural nuance as well. They went to all this trouble because, as we find out towards the end, the Saudar were ugly as sin and would not have been accepted by any alien race they encountered; they needed the shapeshifters to act as their ambassadors.
 * In the Parrish Plessis series, after the hero is infected with The Corruption, the Eskaalim parasite appears in her mind in the form of an angel. It claims that her subconscious mind is responsible for giving it this appearance since she cannot comprehend its true form.
 * In Glen Cook's book Petty Pewter Gods, it turns out that practically all of the gods of the various pantheons are actually refugees from another dimension that feed on faith. Their true form seems to look something like a giant glowing sea anemone - or at least, that's the form of something that tries to break free and into the real world.
 * In Cruel Zinc Melodies, a mysterious presence  under the World Theater's construction-site sends a projected image of Eleanor to communicate with Garrett.
 * The Seleneans in the Star Trek Novel Verse. In their natural state they are only semi-Humanoid at best, and rather ferocious looking. The Selenean Pod Mothers, who have great control over their offspring's genetics, have bred certain broods designed specifically for offworld contact. These individuals, Y'Lira Modan of Star Trek: Titan among them, take a form more pleasing to humanoid eyes, but retain the ability to shift into their natural state if need be.
 * Subverted with Reketrebn in Doug Naylor's solo Red Dwarf novel, Last Human. As a Symbi-morph, it attempts to please Lister by appearing as Kochanski. He tells it not to, as he is missing her deeply. Reketrebn takes Rimmer's form, which Lister definitely doesn't want to see. As a result, Reketrebn takes on its neutral form unless required for practical reasons (such as appearing as Kryten will allow Lister to access his subconscious, as Lister generally knows what to do, but consults Kryten as he lacks confidence in his own intelligence).
 * In Everworld, Senna has her astrally-projected form take the form of a military-looking man when communicating with her followers, wisely suspecting they would find that more authoritative than a pretty sixteen-year-old girl. When she actually brings them to Everworld she eventually creates the illusion of herself as a pseudo-Valkyrie for the same reason.
 * Dionysus also admits that the gods (at least the Olympians) do this, taking whatever form they feel suits their particular profession; he, for example, goes for a more "approachable" look since he enjoys mortal company. When Christopher questions why Artemis (goddess of virgins) would choose to look like a Hot Amazon, Dionysus replies that a pledge of eternal chastity wouldn't be worth as much if men didn't want to have sex with her.
 * In the Dumarest of Terra book Prison of Night, Dumarest meets with a Hive Mind. It takes the form of a religious leader he'd known years before, stating that the hive has assumed this appearance because "the shape is one you find comforting and trust." Dumarest isn't a very trusting person, so this is a strong statement.
 * Con Sentiency has interfaces in the "Beachballs" as the main means for contact with a Caleban—very tenuous, between barely understandable speech and apparently meaningless visual representation. But it turns out this counts as a quite good job, considering the scale of the problem.


 * In Ilona Andrews' Kate Daniels' series, there's a shapeshifting infodealer named Saiman who uses his ability to physically become any man or woman he can imagine in his efforts at ferreting out information and for various social dealings. When he's doing his thirty-six-hundred-dollar-an-hour infodealing business (which, truth be told, he's worth the price because he gets results) in the comfort of his own home, he chooses to look like a pleasant, intellectual fellow approaching forty. The trope is subverting, too, as Saiman really doesn't like his own natural form  So the various striking appearances he crafts—striking men and beautiful women, depending on what he feels is appropriate—are all an effort to make a form he himself is comfortable with.
 * Subverted by Aphrael in the Elenium trilogy by David Eddings (and its sequel, the Tamuli trilogy). Although she is a goddess, she chooses to appear as a barefoot little girl—not so much for the comfort of the humans with whom she interacts, but for her own. She likes to be cuddled and kissed and treated like a little princess, so she adopts the form that is virtually guaranteed to win her such treatment.
 * Her true form isn't that difficult to get around - a gorgeous, pale, nude young woman. Who glows. And flies. And is a source of magic. And can destroy you with a thought, if she feels like it.
 * Played straight in the Tamuli trilogy with Xanetia. The most skilled of the Delphae, when she ventures outside her city, she alters her natural light emission to make herself look like an ordinary Tamul. This is not so much for the comfort of the heroes who are by this point used to the idea but rather for the general public since the general reaction to seeing a Delphae (better known as the Shining Ones) is to run in terror.
 * The Arisians in the Lensman series. Mentor, in particular, has manifested as a giant brain in a jar, a giant brain not in a jar, a hard-bitten detective, a university professor, and a seven-foot woman. Though, given how the Arisians work, this may be less A Form You Are Comfortable With and more A Form That Will Elicit The Desired Reactions.
 * Inverted in the Star Trek: TNG novel Eyes of the Beholders. The Enterprise encounters an artifact of an extinct race that is sending out a psychic beacon that causes insanity with prolonged exposure, is so oddly shaped that they can't look at the thing, and beaming aboard it overloads Data, sends Worf on a homicidal rampage. Although they deduce that it is the cultural legacy of an extremely unique race (It was basically a spacefaring art museum with psychic advertising) Picard orders it to be destroyed, before they realize that they can reprogram Data to be comfortable enough with it to go in and turn it off.
 * In Childhood's End by Arthur C. Clarke, the Overlords hide their true form  for a long time, because they know that we will not be comfortable with it.
 * In The Dresden Files book "Ghost Story",
 * Flatland: A Romance of Three Dimensions, features an interesting variation of this trope. As the Square passes through Lineland, the king of Lineland can only perceive the Square as another Line. When a Solid passes through the plane of Flatland, the Square can only perceive the Solid as another Shape.

Live Action TV
""Well! Since no one seems to care for any corn, we'll have to proceed ahead of schedule.""
 * This happened a lot in the various Star Trek series:
 * The original Star Trek series featured Trelane ("The Squire of Gothos"), the Organians ("Errand of Mercy"), and the Metrons ("Arena"), all of whom took human form in order to interact with the mere mortals.
 * Every time a member of the Q Continuum visited the USS Enterprise, the Deep Space 9 station, or the USS Voyager, this trope occurred. Often, the Q in question would make some sort of snarky remark about having to wear a meatbag suit while doing it. And like the example from Contact above, when the crew of Voyager was taken to the Q Continuum itself, the appearance of this place was a version of this trope because the true nature of the Continuum is beyond the safe limits of mortal comprehension.
 * In a couple of novels, Q tries to expand Picard's horizons; one time he has them take the form of a 3-headed serpent, but it's too much for Picard; another time, when he takes Picard and Data to the Continuum, the unfiltered sensory perception of the Continuum makes Data shut down.
 * And adding to the mystery of how the Continuum chooses to represent itself to humans is that while the one Q we are most familiar with chose to wear the uniform of a Starfleet Admiral basically on a whim (to bother Picard, then updated it later on to bother Sisko), other Q's most often show up as a Starfleet Admiral despite having no real personal reason to, nor even a reasonable way to know how and that it got chosen, in the case of the imprisoned, suicidal Q.
 * The wormhole aliens in Deep Space 9 used the forms of the various cast-members when they manifested to Sisko.
 * Once, Quark found a way of talking to them, and they got to use Sisko's form as well.
 * And the Caretaker in Voyager's pilot episode appears to the crew as a kindly old man in a holographic simulation of a Southern plantation, because it believed that would be a more comfortable venue than its true jellyfish-like form, briefly glimpsed at the end of the episode. Star Trek really did love this trope.

"Joan: Are you-- Are you being snippy with me? God is snippy. God: Let me explain something to you, Joan. It goes like this: I don't look like this. I don't look like anything you'd recognize. You can't see me. I don't sound like this, I don't sound like anything you'd recognize. You see, I'm beyond your experience. I take this form because you're comfortable with it, it makes sense to you. And if I'm "snippy", it's because you understand snippy."
 * After Species 8472 took some mood stabilizers and stopped killing everything, they took human form to rehearse infiltrating the Federation headquarters on Earth. Later they have peace talks with Voyager, which would likely have been difficult in their original three meter tall form, where they kill everything they touch.
 * They were only killing everyone because they thought everyone was like the Borg, who tried to assimilate them.
 * The Changelings. Odo was essentially doing this every episode, which would actually make this the most frequent occurrence of this trope in the whole franchise.
 * It was actually an instance of Character Development when he stopped being so compulsive about A Form You Are Comfortable With and became more interested in experiencing his own shapeshifter-hood, acquiring quarters and outfitting them with various objects to imitate, and "sleeping" anywhere he liked instead of in a bucket in his office. It was also provocative when he met Laas, another one of the Hundred changeling babies sent to explore the galaxy, and one who, bitter at the Solids, had no interest in making them "comfortable".
 * Lorien, from Babylon 5, appears as a wizened old man-alien... but his true form is a starship-sized ball of tentaculared glowy gas...
 * The Vorlons—When Kosh saves Sheridan, he appears basically as whatever each person thinks an angel (or the equivalent) looks like, and he appears in Sheridan's and G'kar's fathers in their minds. It isn't until later, when Ulkesh (and the remaining fragment of Kosh hiding in Sheridan's body, which has apparently called Ulkesh out for a fight to the death) appears outside his encounter suit, that the true form of the Vorlons (thus far revealed only to Dr. Kyle and Lyta) appears: giant flying plasmatic squiddy things. Slightly subverted with the Shadows, who are frequently invisible but always corporeal and vaguely resemble giant spiky scorpions.
 * Interestingly, Londo, an athiest, didn't see anything when Kosh left his suit.
 * Londo SAYS he didn't see anything, but this is LONDO we're talking about. He's so Byzantine even HE can't keep up with his various plots (and that's a large part of how he ends up so badly).
 * Unless, of course the Shadows just never come out of their encounter suits.
 * Both the Vorlons and Shadows play the trope when they try to make one final push to woo the Younger Races in the Season 4 episode "Into The Fire". Sheridan, being convinced by the Vorlons, sees an Anthropomorphic Personification of justice encased in ice. Meanwhile, Delenn, being convinced by the Shadows, sees the people she's been most familiar during her time on B5, one by one, eventually seeing a duplicate of herself.
 * Both the Ancients and the Ori in Stargate SG-1 use this trope. The series even lampshades it stating that the Ancients used to be human-like beings anyway, so taking our form is as natural to them as breathing. If they still breathed, that is.
 * Similarly to the Q Continuum example above, the plane of the Ancients is also presented in A Form You Are Comfortable With - as a homely American diner. Not just any diner, but one Daniel Jackson had gone to as a kid.
 * Interestingly, appears as an overweight guy, which is definitely meant to trick Daniel, as  (of course, his true form would be ).
 * Both types of Ancients in Farscape use this trope to appear to John Crichton: "Jack" of the Endangered Ancients typically appeared as Crichton's father, only manifesting his true insectoid form three times - including his death. On the other hand, Einstein of the interdimensional True Ancients chose the form of a well-dressed gentleman with pitch-black eyes.
 * In Joan of Arcadia, wherein God tells Joan directly, "I look and sound like this because this is what you can understand."

"Zachariah: In Heaven I have six wings and four faces, one of which is a lion. You see this because you're... limited."
 * Played straight and subverted with the First Evil on Buffy the Vampire Slayer. Able to take the form of any person who has died, the First sometimes will manipulate people by appearing as a comforting, departed loved one... but more often than not, it will maliciously choose whatever form will most freak its victim out. And it's really good at it, too.
 * Also Jasmine in Angel. She goes through great pains to manifest as a beautiful black woman in this plane, but her real form that can be glimpsed when she's feeding involves green light and tentacles. Also, anybody who comes in contact with her blood will see her as a rotting corpse.
 * Again used with Illyria who uses the general form of Fred (granted shes blue) despite the fact that it makes some people (especially Wesley) uncomfortable. Leads to a Major Tear Jerker in the final episode
 * Played with in Supernatural, where the Crossroads Demon almost always takes form of a sexually appealing woman. Considering that the demon seals her Faustian deals with a kiss, this probably plays into her advantage. Same goes for Lilith.
 * Subverted in later episodes. The demons will appear in whatever body they've decided to possess, and they don't always pick a body that is sexually appealing. Crowley in particular didn't, and still expected his client to seal the deal with a kiss, much to the (male) client's disgust.
 * In addition, angels have to possess human "vessels" in order to interact with humans, because seeing an angel's true form will burn out a person's eyes and its true voice causes shattered glass and bleeding ears. Castiel eventually reveals his true form is "about the size of your Chrysler Building."
 * Which raises the question of why Lucifer and Michael even needed human vessels to begin with, since neither of them seem to care whether or not they harmed humans. Fighting each other in their true forms would have saved a lot of time and effort, as opposed to spending an entire season . The only answer given so far is "Them's the rules." They're required to have a host, but we don't know why precisely.
 * Played straight in Dark Side of the Moon when the brothers visit Heaven. While there, the garden at the center of Heaven will change its appearance according to what the viewer most expects it to look like, becoming the botanical gardens in Cleveland for Sam and Dean. Also, angels still appear human and wingless, which is even lampshaded by Zachariah:

"Dean: You sure are a lot prettier than the last reaper I saw. Tessa: You saw my true form and flipped out. It kinda hurts a girl's feelings."
 * Reapers also tend to appear in the form of a human to the recently deceased, such as Tessa appearing to Dean as an attractive young woman when her true form proved rather frightening to him.

"Sarah: I guess i should've expected it. Neil: What? Sarah: God is an old white guy. Kurt: It's probably an artificial construct so we won't freak out, derived from TV transmissions. Sarah: How do you know that? Kurt: 300 hours of Star Trek."
 * In the '80s medical drama St. Elsewhere, Dr Fiscus (Howie Mandel) had an out of body experience while in surgery after an accident. During his ordeal, he meets God, who looks exactly like him. God's explanation: "I made you in my image, didn't I?"
 * Parodied in a Christmas special for Everybody Loves Raymond where Rob pretends to be Santa, but Ray's daughter isn't fooled. His response? He had taken the form of her uncle Rob because it's a form she'd be comfortable with.
 * This is immediately Lampshaded by Ray, who says "You're Santa Claus, not a Klingon."
 * Done in the Animorphs live action adaptation, where the Andalite Visser 3 takes the form of a human in order to make his enemies (humans who he thinks are Andalites) more comfortable. If you think that sounds like a poor excuse to cut corners on the show's special effects, congratulations, you're smarter than the target demographic.
 * Seen in Battlestar Galactica, angels appear to characters throughout the series in the form of other characters. Notably Six to Baltar and vice versa, as well as an angel who looks like Leoben to Starbuck.
 * Head-Leoben is the only one who confirms this though. Head-Six and Head-Baltar appear in these forms even when no one is around to see them. In fact,  implies that the Final Five designed Cylon Model Six after the angel they saw, not vice-versa.
 * Not to mention that incident where Head-Baltar appeared to Baltar. Baltar was everything but comfortable.
 * The angelic-like ascended aliens (called Being's of Light)from the original series did this when they needed Apollo's help with a mercy mission. He got a sidekick that only he (and later Starbuck) could see called "John".
 * In Lost, the Man in Black/Smoke Monster can take the form of any person he wants, and he takes different forms to appeal to different people. To Jack, he was Christian; to Eko, he was Yemi; to Ben, he was Alex; to Richard, he was Isabella; and in his final form, when he intended to influence the island's entire population, he was John Locke.
 * He could create hallucinations of almost anyone, but it’s implied that he could only physically mimic a limited number of people. Every solid human shape he takes is of a dead person whose corpse is on the island ("Isabella" never physically interacts with Richard). This would explain why he took the form of Christian in front of characters for whom that form carried no significance; Christian was the most convenient non-threatening form that he had in his repertoire at the time.
 * The Operators, Specialists, et. al. of Sapphire and Steel. Maybe.
 * The Imagin in Kamen Rider Den-O have an intresting take on this trope. They ALWAYS take a form their host has knowledge of, as their form is from their memories. While this normally more comfortable than taking with a random floating orb of yellow energy with no face, it's different in that it's not for the host's benefit but because the Imagin wants a physical form.
 * Played straight in Odyssey 5 when the chararacters meet a member of a race of Sufficiently Advanced Aliens:

Newspaper Comics

 * In one Garfield Story Arc, Garfield's conscience took the form of Garfield's food dish for this reason. (He really looks like everyones mother.)

Religion and Myth

 * This trope is at the least Older Than Feudalism, with gods taking forms that appeal to mortals (Zeus). Indeed, the story of Semele has Zeus forced to show her his true form, which promptly kills her.
 * And seeing as this is Zeus, he's got his reasons to make himself appeal to mortals.
 * Wildly averted in Abrahamic religions. Seeing the face of God is said to result in instantaneous death. Moses, a favored prophet, was however, treated to a view of the back of God. It sent him flying out of a temple and left his face glowing. Additionally, angels tend to have disturbingly non-standard numbers of things like wings, eyes, and even faces. The chariot of God, the Merkabah, is similarly unusual. Ezekiel and Isiah are great sources for descriptions of God as being difficult to describe. Also, keep in mind that these religions generally emphasize God having no physical form; it's considered fairly blasphemous to ascribe one to him. You'd have to ask a rabbi how someone could "see God's face/glory" then.
 * Moses didn't even get to see the form of God, he was only allowed to see His radiance.
 * It's telling about the "true form" of angels when, almost without exception, their first words are "Don't be afraid".
 * The manifestation of God as a human in the form of Jesus is (or at least was 2000 years ago before people got used to it) playing the trope straight then, but subverting the expectations people had at the time.
 * Even the angels were described using this trope, since their descriptions don't normally work in the natural realm. Wings and wheels covered in eyes? They sometimes took on the appearance of humans, and they were still described as looking different.
 * The Tao te Ching is an attempt to do this to the Tao, through a series of analogies.
 * For the most part, the followers of Egyptian Mythology understood that the various forms ascribed to their various gods weren't supposed to be how the gods actually were. Those forms were supposed to be symbolic of concepts and traits found in the gods, with the actual gods themselves being thought to exist as abstract forces.

Tabletop Games

 * In Dungeons & Dragons, most Beholders are insane, convinced that they embody the perfection and any minuscule deviations from it should be exterminated, and thus (being extremely flexible species) wage constant species-wide civil war. It's caused by their deity, "Great Mother" who also spawns different hive mothers in every clutch who in turn spawn different variant beholders. But how it's compatible with seeing Great Mother itself? Simple: every breed individual sees its own features (scaled up, of course).
 * In the few instances from Ravenloft history when the Dark Powers have contacted someone, they've done so with an audio-only inversion of this trope: taunting, tempting and tormenting a nascent darklord using the voices of said darklord-to-be's friends, family, and enemies. In short, A Voice You Are Uncomfortable With.
 * The Emperor of Warhammer 40,000 did this as a matter of necessity, appearing as (very) large human wearing armour because his true form would also expose any viewers to his psychic presense, which even ten thousand years after his apparent death is powerful enough to burn out the eyes of anyone who makes even momentary psychic contant with him and is capable of maintaining a galactic navigation beacon.
 * Sort of. He actually IS a giant man in stupendously ornate armor. Whether he grew into gianthood or performed genetic experimentation on himself is never stated. What he actually masks is his psychic power, not his body. Baseline humans that see him are dazzled by a blinding light about one notch down from a Beatific Vision. Psykers get a wonderful dose of Your Head Asplode. Then he starts actually doing things and it makes sense why he's referred to later on as the God Emperor.
 * In Exalted The Unconquered Sun has appeared in the form of a handsome four-armed human since the time when humans became the dominant race of Creation. Prior to that, he appeared as a golden scaled humanoid tyrannosaurus in honor of the Dragon Kings, who were his most ardent worshippers. He's also capable of assumning practically any form if he wants to make himself more (or less) comforting to another. His reason for assuming other forms is partially as an expression of respect and solidarity, partially for the sake of being comforting and partially because his true form (a humanoid figure of molten gold and obsidian studded with galaxies, with blazing eyes and countless arms) would burn out the senses of practically any being that viewed it.
 * Other Incarnae also have the power to assume more comforting forms. Luna in particular is defined by being a shapeshifter, with a multitude of forms and identities, some of which are specifically assumed to be comforting to others.
 * There's also the implication that some of the jouten (bodies) of certain Primordials serve the purpose of giving them a means of interacting with lesser beings in a context other than complete awe and terror. Note that in most cases, this doesn't constitute actual shapeshifting; they're just capable of existing as multiple bodies simultaneously.

Theatre

 * In Marlowe's Doctor Faustus, the eponymous scholar is appalled by the first form Mephistophilis presents himself in after being summoned (it's never made explicit in the text what that form resembles), and asks him to come back in the shape of a Franciscan Friar.

Video Games

 * Happens a few times in Shin Megami Tensei verse.
 * Persona 2 has Nyarlathotep, an excellent shapeshifter; being a mass of literal living, breathing evil, he often uses his powers to duplicate people to stab people from where it hurts most in the shape of the people they admire or love most by Breaking Them By Talking, and mostly inverting this trope, generally with the purpose of heightening his enemies' despair so they break, general attrition damage, and for shits and giggles. Being born of Humanity's collective unconscious has made him very, very, good at this.
 * And in Persona 4, Teddie, a Shadow, does this unconsciously so as to appear nonthreatening to the humans he wants to become like. Also,
 * In Strange Journey,  disguises himself as Metatron in order to con the Player Character into freeing his power.
 * One character in Devil Survivor 2 is actually an Eldritch Abomination, but appears as a human most of the time.
 * Alex Mercer and Elizabeth Greene, from Prototype, look human enough to begin with, albeit able to shapeshift and turn parts of their bodies into weapons. Eventually, though, you realize that . Later in the game, Elizabeth Green turns into a mountain of flesh and biomass growing out of the sewer at Times Square, giving you a hint of how Alex might truly look. Subverted by the fact that Alex himself genuinely believes he is his human form, at least until someone tells him otherwise.
 * A rare example of this being played for horror comes in Project Origin with Alma. She pins Beckett to a wall, looming over him looking like an emaciated corpse, but then retreats and takes on the form of a healthy, attractive young woman. Made horrifying by the fact that Alma is in love with Beckett, and it's quite clear that she's doing this to appeal to him.
 * The main characters of the Mega Man ZX series have to do this. If you attempt to talk to civilians while not using their human forms, the civilians flip out. The official explanation for this is that they're afraid of you, but this hardly seems to hold for those who tell you that to talk to them, you need to "ditch the crazy outfit".
 * Pretty much all powerful dragons in World of Warcraft have the ability to take on a human(oid) form whenever they want. Some even adopt aliases and pass themselves off as (relatively) normal people to suit their purposes (be they good or evil).
 * That said, the method of getting aliases and infiltrating mortal societies has become so well known that Genre Savvy people can spot a dragon-in-mortal-form from a mile away. In response, some dragons have stopped bothering with perfect disguises and let some of their draconic featured remain visible, thus increasingly subverting this trope.
 * Most dragons prefer to take elven forms, as they believe humans to be inferior creatures. Even Korialstrasz/Krasus, who is pretty friendly to humans, takes the form of an elderly elven mage. Deathwing and his ilk only take human forms in order to infiltrate the human society. Other dragons occasionally appear as other races, such as goblins, but only when they're undercover.
 * Chronormu/Chromie seems to be the only dragon who preferentially adopts a gnome as their mortal form because it suits his/her personality.
 * Played with in Saya no Uta: Saya appears to Fuminori as a cute girl not because she's changed her form, but because Fuminori's altered perception makes her look that way to him; as a result, he's the only person who doesn't go insane just by looking at her.
 * The various dragon gods in Breath of Fire IV each possess 2 different forms, a giant, monstrous form they take when summoned and a smaller humanoid form they take when conversing with the party. During the party's first meeting with Pung Ryong, the wind dragon, he comments "perhaps this form will be easier on your eyes" as his humanoid form appears.
 * Mephasm, an Affably Evil pit-fiend in Neverwinter Nights 2, always takes the form of a purple-skinned half-elf when the player character sees him.
 * So why don't Baalze-whatsit the Hezerou (giant humanoid toad-like thing) and Kolibaro-something and the two other pit fiends in Mask of the Betrayer take on an easier-to-cope-with form? At least the Erinyes and the Succubus in Jerro's Haven have a reason for looking like that...
 * Zaxis outright hates you, the other four probably take pleasure in having such terrifying appearances. Mephasm, being Affably Evil, prefers to befriend those he works with, rather than intimidate them.
 * Male Morrigi in Sword of the Stars. Being powerful psychic beings, they automatically give off a psychic aura that makes anyone looking at them see a divine, 'good' creature from their own mythology instead of their true forms (as an example, most humans see angels). Since the Morrigi are traders and diplomats by nature, this tends to smooth over diplomatic functions with other species quite nicely.
 * Interestingly, this aura is primarily meant to attract females, similar to the tail feathers of male peacocks. Basically, Morrigi females look for a male with the most beautiful (i.e. strongest) aura, while Morrigi males look for a female who can resist their aura.
 * Subverted in The World Ends With You with Joshua, because downtuning his vibe automatically gave him a human appearance. Played more straight with the Reapers, who appear in the Realground without their bat like wings.
 * It is hinted that Yukari Yakumo of Touhou only appears to be a middle aged woman because she specifically altered herself to appear that way. Her gaps, tears in reality she uses for transportation, provide a glimpse of her original appearance, and it isn't pretty.
 * More than just hinted: given what (many) Youkai are, it's probably save to assume that many Touhou characters merely take human form for convenience and to wear frilly dresses.
 * Outright stated with some characters that are shown to change into a human form.
 * Likely the reason the G-Man appears human and yet is so clearly not.
 * In the God Game Black and White (specifically, the first one), the mortal villagers of Eden only see your Godly Essence as a rotating ball of energy with a symbol on it. As the player, you see a hand... one that that reflects everything you've done on Eden. As the developers wrote in the making-of book, there are no mirrors on Eden.
 * Implied to be the case with the shapeshifting Flemeth in Dragon Age II. She notes how "bodies are such limiting things" and alludes to the fact that she's much more than a simple Humanoid Abomination. What she is exactly remains a major mystery of the series.
 * In Mass Effect 3,  appears as the little boy who was killed at the beginning of the game.
 * Played with in Catherine..
 * Final Fantasy X has the Eidolon Bahamut appear to you in the form of a small boy with Bahamut-themed clothing. Though considering how Eidolons are made it's a mixture of this trope and Was Once a Man

Webcomics
"Interdimensional Being: You... don't find it frightening? Orion: Um... well, why a fish? It's not even a particularly freaky fish. Interdimensional Being: Fish are scary! Orion: You're scared of fish? Interdimensional Being: No! It's just... dammit, I'm an interdimensional being. Do you know how tough it is to tailor your intimidation to billions of different cultures? 98% of sentient beings in the multiverse find fish terrifying. How was I to know you came from the other 2%?"
 * Something does this by accident in Beyond Reality. It's trying to not to appear as something the human is comfortable with, but doesn't know much about humans, and thus has to make an educated guess.


 * Hilariously subverted in this strip of Starslip Crisis.
 * The insectoid Princess Voluptua in The Inexplicable Adventures of Bob usually interacts with Earthlings by disguising herself as a beautiful woman. One of her subordinates criticizes her that "'Tis undignified for the heir apparent to dress like a monkey!"
 * The Sovereign of Sorrow in Captain SNES's appearance depends on "how [someone's] mind understands [her]", though she typically appears as female video game royalty. For example, Magus from Chrono Trigger sees her as Queen Zeal and Roy Koopa sees her as Princess Peach.
 * When Sissy in Umlaut House 2 ends up in the far future she meets Volair and first recognizes him as Dr. Lee's husband and then guesses that he's some post-Singularity spook who took on a form that would be neither too familiar nor too strange for her to talk to. Turns out she's right in both cases.
 * Inverted in The Gods of Arr-Kelaan. The mortals-turned-gods can look like anything they want, but they default to what they looked like as mortals because it makes them more comfortable.
 * In Narbonic, a demon coming to claim a fleeing demon's soul does this, picking an image from Dave's head. That image just so happens to be Helen, dressed like a nerdy fanboy's wetdream.
 * In Gunnerkrigg Court Coyote appears as a somewhat stylized coyote -- usually—but his true form can be seen by the spiritually aware. Carefully, as it's like picking out details on the sun.
 * And then there are Norns.
 * In Olympic Dames, this trope is Pan's excuse for appearing as a tall blond human to the leads. He really just wants to get laid without hearing women scream.
 * Played for laughs when Blade Bunny expresses disgust for being stared at by a big gooey dragon's eyeball that is bigger than she is. The dragon then voluntarily shrinks down small enough to punch out.
 * In El Goonish Shive, Pandora "Chaos" Raven seems to be trying to invert this trope by appearing as a little girl. What she says and does is more creepy that way. Though it seems that mostly she adopted it as more appropriate for childish things, like temper tantrumsspoilers!.
 * Also played straight later as she takes the form of Fox, Nanase's summon, to wake her up and get Nanase to listen to her so Nanase will do what Chaos asks with out freaking out too much. Nanase eventually catches on that she's not Fox but by that time she doesn't care and is willing to do what Chaos asked anyway.
 * Lampshaded in Dubious Company. Phred visits Sal and Leeroy as a pair of sweatpants.
 * In Wayrift, the Arweinydd Zemi Dreigiau appears to people in person form or dragon form—depending on his mood. The Arweinydd Zazo also takes on a wolf form to communicate with people, and eventually takes the form of a woman to gain attention from the man she's in love with.
 * For King, from Housepets, the Universes & Unrealities game is an overglorified Dungeons & Dragons game... played by two celestial beings who happen to take the respective forms of a giant eastern-style dragon and a griffon.

"Michael: Clippy. You're taller than I expected. Clippy: I have chosen the form that is most pleasing to you. Michael: (Beat) Is that a gay joke? Clippy: Eh. More a narcissism joke. Plus, this is the easiest way to shoot the finale."
 * Whateley Universe: On Parents' Day, Carmilla's father showed up looking like a charismatic dad of Hispanic ancestry. He's actually the demon Gothmog, child of Shub-Niggurath. In his first appearance, he looked like a giant mass of flesh and slime and eyes and tentacles.
 * On the final episode of Cracked TV, Clippy (after going insane and trying to take over the show) appears before Michael - played by the exact same actor with a sombrero, a fake moustache and a bad Mexican accent.


 * All of the Anthropomorphic Personifications in the Global Guardians PBEM Universe are made of this trope because, being the physical incarnations of ideas, everyone has a different interpretation of that idea. What this means is that two people could be talking to The King (the Anthropomorphic Personification of "The Legend of Elvis Presley") and he'd look precisely like how they think Elvis Presley looks like when they think of Elvis Presley (meaning if one person pictures Ed Sullivan-era Elvis, he looks like Ed Sullivan-era Elvis; if they picture Vegas-era white-tassle pudgy Elvis, he looks like Vegas-era white-tassle pudgy Elvis).
 * On deviantART there is this prose piece called "God Drinks Black Coffee". The main character meets God on the sidewalk in the form of a woman.

Western Animation
""See?! You practically crapped your pants! Except for him, he crapped his pants!""
 * Used in The Venture Brothers When Dr. Venture calls him out for using his dead father's image and bringing up a lot of painful memories, an alien revealed his true form to shut Rusty up and traumatized everyone present.

"Dib: Who--what are you, and why did you transform into giant shoes?! Meekrob: We are beings of pure energy. This is merely a form your human brain can understand. Dib: But--you just looked like aliens before you turned into shoes. Meekrob: Hmm...yes. But you couldn't comprehend that. Dib: Yes I could. (the lead Meekrob slaps him with a shoelace)"
 * Possibly parodied/subverted with The Master, Dr. Orpheus' teacher. We've never seen his true form, so we have no idea is he's human, or what. But instead of taking on forms to comfort people, he seems to choose ones to screw with their heads (or at least to engage in Power Perversion Potential) though he always claims there's a valuable lesson in them.
 * Lampshaded and double-subverted in an episode of South Park. The alien initially takes the form of Stan's father and the kids first think that the whole "alien taking a form you are comfortable with" trope is lame. But when the alien then takes its true form, they scream and quickly ask it to go back to a "comfortable" form. They then spend quite a while going through possible forms (including Santa Claus, Saddam Hussein, and Missy Elliot) until they arrived at a taco that craps ice cream.
 * Not to forget the form of Moses in the Super Friends episode - a giant spinning orange energy prism! Yeah.
 * Not just any spinning energy prism, but a carbon copy of the Master Control Program.
 * This trope is parodied in a later episode, when the "Wall Mart" tells Stan and Kyle he can take many forms. He than proceeds to put on a different hat and ask: "Does this form please you?" and takes on several other "forms" such as the same guy but wearing a jacket.
 * And later in the same episode. "Now I shall reveal my true form!!!" he rips off his (apparently) fake moustache and jumps up and down in place while grunting. This description does not do it justice. Please provide a video link if possible.
 * Found it!
 * Invader Zim gives a humorous example with the Meekrob:

"Steve: Wow! Angelina Jolie! I have so many questions to ask you. Is that whole thing about you sleeping with knives in the bed true? God: I'm not Angelina Jolie, Steve. I'm God. I simply chose the form most pleasing to you. Steve: Oh, you're God. ...So is that thing about Angelina Jolie sleeping with knives in the bed true? God: Yeah. It's messed up, isn't it?"
 * Done twice on The Simpsons:
 * On the first occasion, Homer's guardian angel appears to him in the form of Sir Isaac Newton, "a man you would respect and admire." When he realizes Homer has no idea who Newton is, he instead takes the form of Colonel Klink—which he really didn't want to do.
 * On the second occasion, Homer is visited by the ghost of Cesar Chavez—who appears in the form of Cesar Romero, since Homer doesn't know what Cesar Chevez looks like.
 * In Disney's The Return of Jafar, Jafar's true form of a huge red Genie is too much for thief Abis Mal, so Jafar spends most of the film looking as he did while human. Which only helped a little, since let's face it, even human Jafar is pretty damn intimidating.
 * Steve and God from American Dad, (episode: Stan of Arabia).


 * Oddly, He later appears again as a typical Grandpa God in Heaven.
 * Well, that's how he appeared to Stan, who's something of a Christian fundamentalist, so Grandpa God is probably the only form Stan is willing to accept.
 * "Does this form not please you?"
 * When the Vok talk with Optimus Primal in Beast Wars, they take the form of the head of Unicron, having scanned his mind and determining it to be a "figure of authority" that Optimus would listen to, though it was more likely "A Form You'd Know Not To Screw With". Pulling such a stunt is entirely in character for the Vok.
 * They do show their true form to Tarantulas, when he tries to mess with their Tigerhawk puppet. He freaks out and tries to kill them with a big laser, only to get himself killed. Here is their true form.
 * Star Trek: The Animated Series episode "The Magicks of Megas-Tu". The inhabitants of Megas-Tu do this for their own bodies and their planet's surface so the crew of the Enterprise can comprehend them. Lucien turns the planetary surface to a forest glade, and the other Megans change it to a recreation of Salem, Massachusetts during the Witch Trials.
 * Daria met many holidays at the "Depth takes a holiday" episode. Christmas, Halloween and Guy Fawkes day wanted to start a band, but Cupid and Saint Patrick day wanted them to return home. They are supposed to say that home is "in your hearth", but it was actually in another dimension they could access through a dimensional wormhole at the back of the chinesse food restaurant. The holidays seem and act like common teenagers, and in their dimension they are all at a place that seems like Lawndale High, but which is worse (a quote that Daria and Jane will be repeating in their adult life).
 * In Young Justice,
 * Subverted and Played for Laughs in She-Ra and the Princesses of Power; when Adora first meets Lighthope, the entity appears as a very tall, very intimidating woman; when Lighthope realizes Adora is not comfortable with this form, she changes into a shorter, Creepy Child with pointed ears. Adora quickly asks for the tall woman again.

Real Life

 * Some zoos have been known to feed animals using hand puppets that look like an adult of that species.
 * This is actually necessary for baby primates when humans are feeding them. The human literally wears a monkey suit to simulate the fur of the mom. This way the baby will accept the mother when he's returned to her.
 * It's also necessary for avians. Birds that "imprint" on humans when they are infants will think that humans are like them, or that they are like humans. This can lead to difficulties, if the bird in question is a part of a breeding program to keep the species from dying out. Ducks and geese are best known for this problem, and may actually end up not knowing how to fly (since humans don't). This is referenced in the Discworld novel Guards Guards, in which a human raised by dwarves is likened to a duck raised by chickens.
 * One example of this is the quadrupolar echo pulse sequence in nuclear magnetic resonance spectroscopy. The math works out perfectly, but trying to visualize it invariably winds up with the spin pointing 90 degrees from where the math says it should be and where experiment confirms that it actually is. The lesson here is that once you get into the realms of quantum mechanics, physics really is just math, and what you think of as "physics" is just a Form You Are Comfortable With.
 * Humans instinctively relate to dogs by summoning up qualities dogs and humans share in common (dogs cannot understand space shuttles, they can understand hierarchy, territorialism, tribalism, predation, and familial affection).
