* Thief and Black Mage in ''Webcomic/EightBitTheater'', who regularly have to deal with the stupidity and crazy "logic" of their companions Fighter and Red Mage. ''Especially'' Red Mage, self-professed genius. Considering that characters like Fighter, Red Mage, Black Belt and even Thief have shown the ability to do things that violate the laws of physics simply by ignoring them, one of Black Mage's reactions is a pleading, "How? Seriously, how?" Quite often, Black Mage flies into an impotent rage and stabs the perpetrator in the head if the sheer crazy gets to him; or his mind seeks solace in temporary clinical insanity. Black Mage still hasn't gotten over the pitiful and futile habit of trying to argue sense with the universe. Black Mage has on occasion [[http://www.nuklearpower.com/2005/01/13/episode-502-technical-mumbo-jumbo/ acknowledged that Thief is the only one beside him who is sane]], and vice versa:
-->'''Black Mage''': So, Red Mage, enlighten us. How can a plan that makes '''no sense''' work?\\
'''Red Mage''': One simple reason: [[CrazyEnoughToWork It makes too little sense to fail.]]\\
'''BM''': ''[[FlatWhat What]].''\\
'''RM''': Most plans are critically flawed by their own logic. A failure at any step will ruin everything after it. That's just basic cause and effect. It's easy for a good plan to fall apart. Therefore, a plan that has '''no attachment''' to logic cannot be stopped. The success or failure of any given step will have no impact on the macro level.\\
'''BM''': That's so stupid I can't even see straight anymore.
** The fact that not only are his team-mates insane or TooDumbToLive but even the ''world'' [[strike: occasionally]] usually makes little or no sense certainly doesn't make him feel any better.
---> '''BM''': [[MadeOfExplodium Why would [an iceberg] explode?]]
** White Mage also applies. As do Drizz'l, Princess Sara, and Left-Hand Man Gary.
** Note that BM is an omnicidal psychopath, and Thief is a kleptomaniac near-sociopath with a superiority complex. Sanity is relative. In fact, they all tend to juggle with a SanityBall.
* Cucumber of ''Webcomic/CucumberQuest'' functions as this, mainly by being one of the only heroic characters to [[AvertedTrope avert]] ContractualGenreBlindness.
** During the prologue, he suggests that the best option would be to destroy the [[SealedEvilInACan Disaster]] [[PlotCoupon Stone]] to prevent the awakening of the Nightmare Knight. Despite this, his GenreSavvy [[BloodKnight little]] [[JumpedAtTheCall sister]], deliberately [[InvokedTrope invoking]] YouCantThwartStageOne, just willingly GIVES it over to the enemy so that their epic quest wouldn't end prematurely & would have a BigBad for them to fight.
* This is the schtick of Atomik Lad in particular in ''NuklearAge''. While Mighty Mettalic Magno Man and Rachel are also sane, the former is often a witting accomplice to Nuke's insanity, while the latter is generally more interested in watching. Atomik Lad notes in the Court Segment that perhaps he is the insane one, because everything would make more sense that way.
* Ardam in ''Webcomic/{{Adventurers}}'' questions -- and often strongly objects to -- the inexplicable physics and plot-related idiosyncrasies that exist in his world. Although these objections are perfectly intelligent and reasonable in the real-world sense, they're of no practical use to his situation, making him ultimately an example of WrongGenreSavvy. Karn, the main character and his best friend, is the reverse -- he's GenreSavvy, but tends to come off as a bit of an IdiotHero (often BECAUSE of being GenreSavvy).
** Ardam and Karn seem to switch places early on, in that Karn started the sane one and learned the logic of the land, whereas Ardam accepted the madness but went sane later on.
* Cherry from ''Webcomic/RPGWorld'' is another example of a character who doesn't quite grasp the video game logic she is living in.
* Reluctant sidekick Paul in ''[[http://www.man-man.org Man-Man]]'' is the only one who really sees that an non-powered idiot in a costume doesn't make a superhero, that renting the basement to your cheese-fixated evil-genius nemesis is a strange idea, that ideas have downsides or that in his world "superhero/villain" appears to be a synonym for "nutcase".
* Roy, from ''Webcomic/TheOrderOfTheStick'', typically takes this position at various points throughout the comic with his level-headed views. The SanityBall often trades hands in ''[=OotS=]'', generally to whoever's more experienced, grounded, or alive at the moment.
** Durkon for a time seems to be the sane one of the part of the group with Hinjo, though he passes it to Hinjo himself every so often and takes his time worrying about the tree army sneaking up on him.
** Celia is even more so, due to basically being a normal person who doesn't really like to fight or kill. No wonder she hooked up with Roy. Celia seems like the sane person in the party, and moral too... right up until she starts strictly applying naive, kindhearted moral choices to situations with thieves' guilds and mad [[strike: scientists]] mages. Once she starts trying to use "Can't we all just get along?" style speeches to murderous cutthroats, her position of sanity degrades rapidly.
** Haley is the sane one in her mini-group. But ''almost'' everyone gets their turn at pointing out how crazy everyone else, or the world, is being, so it might be that any adventuring group is only allowed one sane person at a time. [[http://www.giantitp.com/comics/oots0539.html As she said]] while caught between StupidGood Celia and StupidEvil Belkar, "I wonder if the gods would be offended if I just prayed directly to Roy for strength not to strangle them both".
** [[DragonWithAnAgenda Redcloak]] is most definitely the Only Sane Man in [[FiveBadBand Team Evil]], being the only non-Mook who is not [[ForTheEvulz evil for evil's sake]], a childish epic-level monster, a goth with a [[NightmareFetishist crush]] on her evil [[DemBones skeletal]] [[EvilSorcerer sorcerer]] [[EvilOverlord boss]], or a wisecracking insect with no regard for the [lack of a] [[NoFourthWall Fourth Wall]]. Granted, if you've read ''Start of Darkness'' you know Redcloak has issues too, but the others have ''subscriptions''.
** Redcloak's brother Right-Eye was so sane that he eventually abandoned Team Evil entirely to attempt peaceful co-existence with humans. He was doing pretty well too, until [[{{Jerkass}}Xykon]] showed up again.
* In ''Webcomic/TheInexplicableAdventuresOfBob'', Bob ''would'' fit this trope if not for the fact that he is, [[WeirdnessMagnet totally unintentionally,]] the cause of most of the insanity around himself; and that he is now [[GenreSavvy getting pretty used to it.]] His girlfriend Jean epitomizes this trope though, and is always capable of taking a few steps back and recognizing the absurdity of Bob's problems -- an acuity which invariably makes her life more difficult, as she must still deal with those problems even while recognizing how nuts they are.
* ZoŽ used to take on this role during the early years of ''Webcomic/SluggyFreelance''. She's still usually the most grounded member of the cast, but over time she's gotten used to the bizarre characters and events that fill her life.
-->'''Zoe:''' ''[[http://www.sluggy.com/daily.php?date=990202 You summoned a demon for beer!?!]]''
-->'''Torg:''' The liquor store was closed.
* ''[[http://www.jaydenandcrusader.com Jayden and Crusader]]'''s character Crusader started out as strange as the rest of the cast, but slowly has flipped to playing the straight man in a household which involves a particularly violent atheist with ''no sense of humour at all'', a mentally insane former-assassin and a possibly insane, possibly time-travelling scientist who wears a top hat, acts like he's from the 19th century and has been known to breed man-eating anteaters.
** [[http://www.jaydenandcrusader.com/2009/03/16/page-115/ Recently]] Crusader has been acting a little insane again because, in the words of the creator 'Crusader hasn't been crazy for a while. I decided to rectify that.'
* TeamDad Dwayne in ''GeneralProtectionFault'', {{lampshade}}d [[http://www.gpf-comics.com/archive.php?d=19981212 here]].
* Arguably, Florence (or Winston) in ''Webcomic/{{Freefall}}''
** Oh, it's Florence. She's constantly having to fix problems caused by Sam and Helix, and most of the other characters exhibit very odd personality traits (kleptomania, unchecked bureaucratism, enslaved to programming...) which she has to deal with.
* Chloť in ''Webcomic/{{Frivolesque}}'' is arguably the only "normal" girl among the five main characters. Much to her chagrin.
* Dimo in ''Webcomic/GirlGenius'' plays this role to his slightly loopier fellow Jagers, Oggie and Maxim. Consider the following exchange (with heavy FunetikAksent), on Gil:
--> '''Maxim:''' Hy vill teach him how to impress de gorls!\\
'''Oggie:''' Hy vill teach him about de birds und de veasles!\\
'''Dimo:''' Und hy vill teach him how to ''avoid those two''.
** Violetta, [[http://www.girlgeniusonline.com/comic.php?date=20090911 in contrast]] with surrounding [[MadScientist Sparks]] and their minions.
--->'''Violetta''': You mean to tell me that you knew that guy ''by name'' on ''Castle Wulfenbach'', and it ''never'' occurred to you that this guy, with the ''same name'', might be the mystery son the Baron had been hiding all these years?!
** Klaus Wulfenbach is essentially the OnlySaneMan to the whole of Europa.
** '''Moloch Von Zinzer''' repeatedly plays this role with all the Sparks surrounding Agatha Heterodyne.
** In [[http://www.girlgeniusonline.com/comic.php?date=20120113 this strip]], a nameless soldier is the only one not immediately convinced that Gil is who he says he is just because Gil has an [[NiceHat impressive hat]].
--->'''Gil:''' (punching said soldier out) "Once all this is settled, ''you'' get a promotion."
** '''Krosp''' plays this constantly. Odd that the only sane man is a cat.
* Central to the premise of Ursula Vernon's ''Webcomic/{{Digger}}'', which makes great play of this as a racial characteristic of wombats in a universe where folklore is living history and 'magicked-up' tunnels are occupational hazards. More specifically, it follows the adventures of one young wombat dumped via hazardous tunnel into a world featuring a god in chains, talking statues, living shadows, oracular slugs and homicidal vegetables. Among other things.
* Aeris in ''VGCats'' seems to be the sanest. Mind you, this is by comparison to:
-->'''[[CloudCuckoolander Leo]]''': Look! I typed in "poop" I'm so witty!
-->'''[[AuthorAvatar Pantsman]]''': Criminals don't catch yourselves, you know. Except Dr. Van Kruglor's self-catching robots. Those were just confusing.
-->'''[[HulkSpeak Krug]]''': No, taste of suffering too expensive for Krug.
-->'''[[TheDitz Dr. Hobo]]''': Ya know I vass normal once. I came to work vith a tie and suit and sometimes panfs.
* The [[AllTrollsAreDifferent trolls]] of ''ErrantStory'' have this as their [[PlanetofHats hat.]]
* [[BobAndGeorge George]] a lot of the time. [[BobAndGeorge Bob]] as well, but you know, he's evil. Sometimes [[VideoGame/MegaMan Proto Man]] but he's more of a [[MetaGuy guy made of Meta]]. Roll doesn't count. She's a woman.
** [[http://www.bobandgeorge.com/archives/020112c And Mega Man, even]]
* In ''Webcomic/CaseyAndAndy'',the only sane one usually alternates between Mary and Jenn.
** It's Mary, seeing as how Jenn thinks nothing of being inter-dimensionally kidnapped for two weeks and then carrying on a conversation that, from the other person's point of view, has only been going on for less than a minute.
* The Space Pirate newcomer to ''PlanetZebeth'' is serving this role, seemingly being the only Space Pirate-affiliated character in the entire comic who actually remembers that they have any kind of mission or organization (as opposed to Ridley, who's opened a bar, Kraid, who just gets drunk and chases Samus around (not necessarily in that order), and Mother Brain, who hasn't really been doing much of anything lately).
* Horse-Man in ''UnwindersTallComics''. It helps that he's [[CoolOldGuy the oldest of the main cast]].
* [[TheChewToy Conrad]] of HannaIsNotABoysName seems to [[http://hanna.aftertorque.com/?p=205 directly address this]].
* Kaitlyn Hu from ''WebComic/{{Precocious}}''. Her time spent observing the others has built up remarkable insight into the social dynamics of the class. She employs this to great effect [[http://www.precociouscomic.com/archive/comic/2010/09/05 starting in this strip.]] The ensuing conversation provides her with justified time in the spotlight.
** Although Kaitlyn is the WordOfGod entry in this category, Max has [[http://www.precociouscomic.com/archive/comic/2010/08/28 played the role]] from time to time.
* In ''PlatinumGrit'' Kate Provocski is the only major character able to comprehend that all the impossible things going on around them are... well, impossible. And she's really starting to stress about it.
* Sloan of ''{{Snowflakes}}'' gets put in this position a lot, though she's not without her own neuroses.
* ''WebComic/EerieCuties'': [[SugarAndIcePersonality Brooke]] and [[NiceGuy Ace]] share this distinction:
** Brooke is typically the most levelheaded of the bunch and often shows a surprising amount of maturity to say she's only 14 years old [[spoiler: (now 15, as of the timeskip)]]. Such as the time she exhausted herself while trying to keep an eye on [[GenderBender girl-Kade]] [[http://www.eeriecuties.com/strips-ec/hello_aceford so he wouldn't do anything he'd regret, later.]]
** And, while they were dating, she and Ace, tried to resolve the problems they were having in their relationship [[http://www.eeriecuties.com/strips-ec/couples_counselling by openly discussing it.]] Though they were abruptly cut off by [[JerkassGenie Tia's meddling.]]
* Karkat of ''Webcomic/{{Homestuck}}'' is the OnlySaneMan among the Trolls, which isn't really that hard since trolls are ''weird''. He admits that [[TeamMom Kanaya]] is the only Troll who might be saner than him. For the humans, it might be Dave, since he's the only one who's not a {{Cloudcuckoolander}} or [[spoiler:[[GoMadFromTheRevelation off the deep end]]]].
** Kanaya's counterpart Porrim fills this role for the Beforan trolls. The rest of the group consists of an agent of dark forces (Kurloz), a guy with severe brain damage (Mituna), a LargeHam trying to hide something about herself she doesn't like (Latula), a generally nice guy who just happens to be a pushover (Rufioh), two {{Jerkass}}es (Cronus and Damara), two obsessives (Aranea and Meulin), [[BreadEggsBreadedEggs an obsessive jerkass]] (Kankri) and...Horuss, who is just kind of weird and crazy.
** For the [[spoiler:Alpha-universe humans]], it turns out, surprisingly enough, to be ''[[HardDrinkingPartyGirl Roxy]]''. Dirk is a massive pile of issues and clinginess, Jake is [[ObliviousToLove clueless]], self-centered, and a bit of a jackass, and Jane is suffering from both [[spoiler:the Batterwitch's brainwashing]] and severe teenage angst. Roxy, who's mostly not involved in the convoluted [[TriangRelations love triangle]], is left to look on in bemusement and try to sort out everything herself.
*** Best demonstrated during the [[spoiler:Trickster Mode]] debacle, where Roxy's reaction to having two of her friends turn up, apparently high and possessing superpowers, is "oh dear god" followed by ''hiding''.
* Parson Gotti, aka Lord Hamster, in ''{{Erfworld}}''. Somewhat [[JustifiedTrope justified]] since he was summoned in a world where physics follow the rules of a turn-based wargame. Lampshaded by [[DeadpanSnarker Jack Snipe]] in book 2 :
--> '''Lord Hamster:''' Yet the enemy ''hasn't'' attacked her yet. And that's because...?
--> '''Jack Snipe:''' Because... it wouldn't be ''Noble''.
--> '''Lord Hamster:''' Right, because the enemy is crazy too. Got it.
--> '''Jack Snipe:''' Indeed. As a ''sane man'', you are badly outnumbered again, my good Lord. Perhapes you should defect, and join us all.
--> ...
--> '''Lord Hamster:''' [[UnspokenPlanGuarantee ...It involves turning this battle into a food fight.]]
--> '''Jack Snipe:''' Bravo, lord, 'twas a splendidly speedy defection.
** He generally seems to be the only person on Erfworld who really understands strategy ''at all''. No-one else seems able to cope if their initial plan fails or plan much more than stacking bonuses, with the possible exception of Charlie.
*** Although Jack has seemed to take to the idea like a boat to water.
--->'''Jack:''' "Lateral Thinking." For that wonderful phrase alone he was forever in his Lord Hamster's debt.
* Space Hojo and Son Gohrotto in ''Twisted Kaiju Theatre'' often play this role. They appear to be the only two members of the Toxic Pirates who aren't lunatics, idiots, or assholes.
* Mimic in ''RustyAndCo''.
* Snippy in RomanticallyApocalyptic. Although Engineer fits this trope to some extent too, Snippy is the one who mostly has to deal with the Captain and Pilot's insanity, and is for the most part sarcastically accepting of his role.
* BittersweetCandyBowl has Sue, the only one not caught up in the drama surrounding her group of friends.
* Almost everyone in APTComic feels like this at some point, and thanks to how some jokes work it tends to be true.
* Most of the jokes in [[http://eqcomics.com/ Edmund Finney's Quest to Find the Meaning of Life]] revolve around the protagonist being a perfectly sane and logical guy...wandering through a universe populated entirely by total lunatics.
* CK from ''Webcomic/CommanderKitty'' finally ends up this way after CharacterDevelopment, to the point [[http://www.commanderkitty.com/2012/08/05/whos-the-crazy-one-here/ he's the only one who belies escaping Zenith central should be their top priority]] while everyone else grabs the IdiotBall and forces him to get a new costume. {{Lampshaded}} in the page's title.
* ''Sonichu'' has Magi-Chan, who is the only one that doesn't kiss Chris's ass all the time. Though there are some unfortunate side jobs of his AllThereInTheManual.
* [[MythologyGag D'artagnan]] in ''Webcomic/{{Ghettonauts}}'' seems to be the only character capable of non-surreal thought and intelligence. He suffers for this.
* In ''Webcomic/MenageA3'', sanity tends to be contingent at best:
** Junghan and Amber have both played this part briefly, but never really settled into it. Minor character Allie sometimes looks like an only sane woman when she's talking to her colleague Sonya.
** Gary might qualify if he wasn't so often the ButtMonkey and/or the AccidentalPornomancer. However, he has his own issues that might exclude him from the role anyway.
** New character Peggy [[http://www.ma3comic.com/strips-ma3/you_hurt_by_dooooze demonstrates how this trope is performed here.]] A little later, in the May 09, 2013 strip (#739, NSFW), she perhaps realises that she's got the job. Her first scenes (which involve her dumping a bowl of pasta over her boyfriend's head in the course of breaking up with him) suggest a degree of flakiness of her own, but by the standards of the comic, she's a beacon of sanity.
* [[VideoGame/GodOfWar Kratos]] plays this role in ''[[Webcomic/ZeusGodlyGoodtime Zeus' Godly Goodtime]]'' among the group that visits NintendoLand. He has to put up with the antics of [[AmazinglyEmbarrassingParents Zeus]], as well as [[BigEater Fat Princess]], [[{{Keet}} Parappa and Spike]], who were invited along by Zeus.
* In this one shot[[http://existentialcomics.com/comic/23 Existential Comic]] Immanuel Kant plays this role to the other philosophers, who can't help but try to exert their own views of philosophy onto the game, while Kant clearly just wants to kill some Orcs.
