Solid Snake: Pipe down kid. [goes into Thousand-Yard Stare] After a while, you just stop asking these questions.
Being new to a group or setting helps the latecomer notice that everyone else isn't operating with a full deck.
Being the Sixth Ranger, Na´ve Newcomer, or rookie member means that you're likely absent from all the mental leaps and decisions that your predecessors all took. Because of that, none of them can Spot the Thread or notice that there's something incredibly wrong about the whole picture.

- WORKING!!: Early on, the series follows Souta, the new part-time waiter, as he discovers one after another the various quirks of his co-workers. Said quirks no other co-worker seems to be bothered by, no other co-worker seems to bother with, no other co-worker bothered to warn him of, and no other co-worker bothered to even mention. The restaurant turns out to be a Dysfunction Junction alright. But Souta himself does make quite a contribution.
- In K-On!, Azusa joins the club in their second year. Her relationship with the rest of the band starts off very shaky due to this, with her pointing out how lazy and unmotivated they seem to be, and how little they seem to focus on their club activities over drinking tea and eating snacks. In their defense, those things were conveniently exaggerated upon her introduction, with much of what they're not doing heavily implied to have been happening off screen prior to that point (otherwise Yui, for instance, wouldn't even be able to play her instrument), but it's played straight from Azusa's perspective.
- According to Word of God, this was the reason that the Scarlet Spider's debut battle was against Venom. Venom was one of Spider-Man's most dangerous and insane foes, but during this period of time, Spider-man had entered a non-aggression pact with him, where the two would basically leave each other alone. Peter at this time was married and Venom was well aware of his true identity, so Peter was partly motivated by a desire to protect his family. Despite this, some writers felt that this was horribly out of character for Peter Parker, and expressed their feelings through Scarlet Spider, who is very pissed off that Peter made this deal.
- Superboy and Supergirl were this for the original Legion of Super-Heroes; as people from the present day, they understandably didn't know much of anything about life in the 30th century, nor what kind of crazy adventures the Legion got up to. This made them Audience Surrogates who could ask relevant World Building questions, allowing the comic to avoid constant As You Know moments.
- Peanuts: Franklin was like this, questioning bits of weirdness that the other characters took for granted such as Snoopy's World-War One helmet and Lucy's psychiatric booth.
- Dragon Ball Z Abridged: Trunks, despite growing up in a post-apocalyptic Bad Future, is a relatively normal and well-adjusted young man. This leaves him very unprepared for the insanity of the Z-Warriors when he goes back in time. Especially where his father is concerned.
- Several characters in The New Adventures of Invader Zim play this role as they are added to the cast, including Norlock, Steve, Viera and Tenn.
- Mr and Mrs Gold: When Emma first meets Rose, she sees her walking throughout the square with her nose in a book, every other pedestrian and driving car do not find it the least bit concerning or something to notice, as if she has been doing the same walk with them for years (for 28 years even). Naturally, Emma is the only one to think this is strange.
- In Steven Universe And The Hunters Of Arcadia, it does not take long for Jim and Claire to realize just how justified their trip to Beach City was when they saw Steven and Connie ride a pink lion that can walk on water leave via portal.
Jim: Claire, you saw that ri-
Claire: I have eyes Jim.
- In Captain America: The Winter Soldier, Captain America (who spent several decades in Suspended Animation) is the only person in SHIELD to see something wrong with the organization's plan to launch a fleet of super-accurate, nigh-unstoppable aerial gunships to patrol the world and enforce peace at gunpoint. It turns out that he's completely right, because HYDRA has been running SHIELD for decades at that point, and once those ships are in the air, they will wipe out the millions of people worldwide who could ever possibly pose a threat, effectively letting them Take Over the World in one fell swoop. Cap spent about 65 years being frozen, reinforcing the trope more since he is missing generations of angst that have led to SHIELD deciding on this course of action.
- Jasminum begins when an art restorer and her daughter arrive at a monastery that houses a bunch of lovably quirky monks.
- Happens often with the study group in Community, but a stand-out example is Todd, who briefly has to join the study group to make equal pairs. They squabble so much over who has to pair up with him that they don't get the assignment done at all, and in the end Todd calls the biology professor in tears.
- The Last Man on Earth: By the time Louis joins the cast in season three, the group has gotten used to Phil/Tandy's peculiar logic. Louis grows exasperated not only at Phil's antics, but also by the others' blasé attitude towards them.
- Epic Battle Fantasy: Anna is new to the entire adventuring thing and isn't used to some of the questionable things the team does at times.
- Mass Effect:
- This happens on a galaxy-wide scale in regards to humanity entering Citadel Space. By the time the rest of the galaxy discovers humanity, a multi-species civilization had existed in its current form for millennia and and Hats had been distributed to everyone based on their species' traits relative to others. ("You're smart and beautiful". "You're tough and uptight." "You're big and stupid." "You're weak and greedy.") This gave humans the advantage of looking at how each other species have fared with specific hats (at one point noting how Fantastic Racism has completely screwed over the quarians and krogan). Humans thus react extremely bitterly to being marginalized or compartmentalized in any way. This, however, makes members of other races assign "pseudo-hats" to humanity instead.
- A more immediate example would be James Vega in Mass Effect 3: he is just an ordinary human marine who gets swept up with Shepard's highly eclectic crew when the Reapers invade and spends most of the game trying to adjust to their quirks. Even his nickname for Shepard is "Loco" ("crazy" in Spanish).
- Even applies to Humanity's military tactics, since according to the Codex humans invented the idea of a dedicated carrier ship. Other races had battleships with small hangars, but nobody had ever thought to dedicate a whole ship to launching fighters.
- Hiimdaisy: Played for Laughs in Let's Destroy Metal Gear series, in which every protagonist plays the Extreme Doormat/Straight Man to the insanity going on. The page quote above is recited to new protagonist, Raiden, by previous protagonist, Solid Snake, while Snake sports a post-traumatic Thousand-Yard Stare.
- Red vs. Blue has this role shift from character to character, with the newest member of the [[Ragtag Bunch of Misfits generally taking the role until they find their niche in the cast. At first, it was Frank "Doc" DuFresne. Then it shifted to Agent Washington when he arrived, followed by Agent Carolina, then the leaders of the Chorus forces, then Dylan Andrews... the role is in flux but each time results in a different brand of comedy.
- Justice League Unlimited: Green Arrow joins the team as a Badass Normal joe without even the benefit of being a Crazy-Prepared Chessmaster like Batman (and he also happens to be a hardcore leftist). He is constantly one to question whether or not Cadmus has a point about being afraid of the Physical Gods taking justice into their own hands. In fact, this trope was invoked by the League itself, who wanted him to be their Morality Chain.
- This was the concept of The Simpsons episode "Homer's Enemy". Frank Grimes is an ordinary guy who gets a job at the nuclear plant and is confounded that Homer is Too Dumb to Live and that everyone else simply accepts it. He is, however, a Deconstructed Character Archetype because of two details: 1) He becomes so angry about this fact that he becomes obsessed with proving how stupid Homer is and it results in him losing his mind and getting himself killed and 2) what gives him the "logical" perspective is not really (Word of God notwithstanding) being "a real person", but having suffered such a hard-core life-long barrage of the Diabolus ex Machina that he's as absurdist a character as any Simpsons regular, only aiming for angst rather than laughs.
- Futurama: This was the role of Professor Fansworth's clone, Cubert, in his first appearance. Having been literally born yesterday, he was there to point out the show's many scientific inaccuracies and logical inconsistencies. This aspect was abandoned in later appearances, when Cubert came to embrace the show's nonsense.
- In the Steven Universe episode "Gem Harvest", Steven meets Greg's cousin, Andy DeMayo, who hasn't seen him in years and doesn't know about the Gems or Steven's adventures with them. Andy is baffled by the Gems' powers, and reacts with fear, concern, and Anger Born of Worry when he hastily tries to leave the family dinner in his biplane and Steven flies after him with Lapis's help, only to nearly fall into the ocean. Interestingly (and hilariously), he actually seems to immediately accept the fact that the Gems are extraterrestrial beings... but he's super mad because they're not legally American citizens and his family has been letting them live with them. And yes, an "illegal alien" pun is indeed used in the episode.
- In the Adventure Time ministry "Islands", several isolated remnants of human colonies are discovered, one of which is governed by Finn's biological mother, Minerva, who is the last of the "Helper" caste that managed to survive a lethal plague by uploading her dying body into a computer network. She wants Finn to also upload so she can protect him from danger forever, but Finn tries to convince her that the outside world isn't so bad by showing her his memories. Her response to his many adventures in Ooo is... mixed.
- Milo Murphy's Law actually begins with one — while everyone else who Milo knows has long ago accepted that he's Born Unlucky and The Jinx, the first episode has him meet Zack, who just moved to town and thus serves as the show's Audience Surrogate. A later episode also gives this role to Zack's father, the only person who doesn't initially believe in the Murphy men's Hereditary Curse.
