History Main / MrExposition

* ''VideoGame/PaperMarioTheThousandYearDoor'':
** Professor Frankly serves this role, and Merlon fills this role in ''VideoGame/SuperPaperMario''. The first game of the series, having a simpler plot, seemingly doesn't need one.
** In the field, Goombario and [[{{Expy}} Goombella]] have actual powers related to exposition, able to tell you about your surroundings, people and [[EnemyScan enemies]].

* In ''Webcomic/{{Distillum}}'', this seems to be Sidney's job. Jamie has shades of it in the beginning, but he's TheNarrator.

* ''Webcomic/{{Castoff}}'' isn't one for InfoDump, but every now and then, somebody needs to explain the theory and practice of magic. Most of the time this someone is the team mage, Arianna.

* ''Film/JurassicPark1996'':

* ''Film/JurassicPark'':

-->"A DNA strand, like me, is the blueprint for buildin' a livin' thing. And sometimes, animals that went extinct millions of years ago, like dinosaurs, left their blueprints for us to find. We just had to know where to look!"

* ''WebAnimation/SonicForHire'': Throughout a few times, Franchise/{{Sonic}} brings up on how Tails constantly narrates their current situation.

** Lorraine [=McFly=] serves this purpose in the first two movies. In ''[[Film/BackToTheFuture Part I]]'', she explains the circumstances of how she and George [=McFly=] originally met and fell in love. In ''[[Film/BackToTheFuturePartII Part II]]'', she explains Marty's problem with [[BerserkButton being called "chicken"]], and how it got him into a car accident which changed his life for the worse. She also filled Marty in on everything that had changed in the AlternateTimeline.

*** Solas ''loves'' learning and teaching people new things, so he greatly respects a curious mind. He's the only party member to earn minor approval bonuses just from asking normal questions.

** Twilight herself tends to grab the Exposition Ball whenever she appears in an episode but isn't the [[IncrediblyLamePun mane]] focus of it.

** In the [[GodzillaKingOfTheMonsters 2019 sequel]], this role is given to Dr. Ilene Chen. Being able to provide lengthy exposition dumps about {{Kaiju}} on a moment's notice seems to be a prerequisite for working with Monarch.

->''"I know! That's what I told 'em, but no! All the cruddy exposition goes to me! I've got to talk and talk and fiddle with the computer and talk some more and fiddle and talk! I feel like [[Franchise/StarWars Obi-Wan cruddy Kenobi!]]"''

* In Creator/CSLewis' ''Literature/ChroniclesOfNarnia'':

* Ariadne from ''Film/{{Inception}}'' came off as improbably perceptive because of a somewhat borderline example of this trope.

* In ''ComicBook/TheLegendOfZeldaALinkToThePast'': In the Dark World, Link discovers a shrine where he can rest before going on. As Link begins to fall asleep, a nearby tree sprouts a face and begins to tell him the story of Ganon and the Triforce. The talking trees play a similar role in the game, while the gist of the tree's story appears in ''[[VideoGame/TheLegendOfZeldaALinkToThePast the ALTTP prologue]]''.

** And whenever Noa goes up against enemy Labor units, he usually gives her a brief analysis of their make and model, as well as any design flaws they may have. Highlighted during the the tunnel scene near the climax of ''[[https://www.youtube.com/watch?v=jKFtPdCysR4 Patlabor: The Movie 2]]'', where Asuma provides intel on the Ixtl units and devises how to systematically take them down.
* Brock from ''Anime/{{Pokemon}}'' (and later Cilan) became this more as the series has gone by. [=RotomDex=] also serves as this in ''Sun and Moon''.

** ''Manga/PhantomBlood'': Perhaps one of the most memorable examples from the series, Robert E. O. Speedwagon narrates almost every single fight that Jonathan take part in, some percieve it as annoying, but most older fans like him.
** ''Manga/GoldenWind'': Pericolo is the one who informs Bucciarati's group of Trish's identity as The Boss' daughter, provides a brief explanation of Trish's mother and informs the group that she is being targeted by La Squadra.
** ''Manga/SteelBallRun'': Through Mountain Tim, the audience learns the way of obtaining a Stand, and that's by passing through the Devil's Palm and surviving.

->'''Inumuta:''' A Three-Star Goku Uniform unravelled by pulling out a single thread! How can that be?!\\

* In ''Anime/{{Patlabor}}'', that's usually Asuma's job:

* ''LightNovel/{{Durarara}}'''s resident nerdy motormouth, Shinra Kishitani, is usually the first to offer any sort of explanation as of the weirder elements of the series such as "how can Celty see, hear and smell if she has no head" or "[[MusclesAreMeaningless how can Shizuo be so damn skinny and so damn strong at the same time?]]" The only one whoever seems particularly interested in Shinra's hypotheses are Shinra himself, so his explanations are typically either ignored (by Celty) or interrupted with physical harm (by [[VitriolicBestBuds Shizuo]]).

* Tabitha's butler in ''LightNovel/TheFamiliarOfZero'' spends about five unbroken minutes spilling Tabitha's back story to someone he'd never even heard of before who just happened to show up with Tabitha at her mansion.
** Although, perhaps he does this just to counteract Tabitha's natural tendency not to give any exposition whatsoever. She's like a version of [[LightNovel/HaruhiSuzumiya Nagato]] that only ''sometimes'' answers direct questions.

* ''LightNovel/HaruhiSuzumiya'' hangs a lampshade on this; Kyon, the sarcastic narrator, constantly tells Koizumi, the Mr. Exposition character, that he talks too much and no one cares what he has to say.

* Anos Voldigoad, the eponymous "Misfit" of ''LightNovel/TheMisfitOfDemonKingAcademy'' is ''very'' fond of doing this to allies and enemies alike. For context, he was an extremely powerful and infamous Demon King who died 2,000 years ago and after reincarnating in the present-day with his powers and memories intact, he has discovered that technology, magic, and much of the world's history have been lost or outright mangled. In combat, he is all too happy to explain to his opponents exactly why their countermeasures, ambushes, and attacks are having zero effect on him. Outside of it, he is all too eager to go into lengthy explanations about magic and the world to set the record straight and because he's also a proud, arrogant individual who ''knows'' he's objectively right all the time.

* Seijirō Kikuoka/Chrysheight from ''LightNovel/SwordArtOnline'' debuts in the CompilationMovie as a person as a government agent who actively demands an exposition and then gives ones in return. He and [[TheHero Kirito]] make a field trip over this trope whenever they're onscreen together.

* Shizuno fills this role in the first episode for ''LightNovel/WorldBreakAriaOfCurseForAHolySwordsman'', when explaining how the coliseum is in a different dimension than the school. Therefore any damage they suffer there doesn't transfer over when they go back. She also explains to Moroha about how summoning weapons works after Ranjou and Isurugi summon theirs.

* In ''Literature/QualiaThePurple'', Tenjou is the one who introduces most of the [[UsefulNotes/QuantumPhysics physics concepts]] relevant for the story, which is understandable considering her position.
* ''Literature/TwentyThousandLeaguesUnderTheSea'': TheProfessor Aronnax and Captain Nemo take turns at it.
* John Schuyler Moore in ''Literature/TheAlienist''.

* In the ''Literature/HIVESeries'', Laura and [=H.I.V.E.mind=] share this role.
* ''Literature/TheHungerGames'': Happens a number of times with Plutarch Heavensbee.
* The newscasters from ''Literature/InTheYear2050AmericasReligiousCivilWar'' frequently break up the action to discuss events over 30-years-old.
* Mike Hanlon in Creator/StephenKing's ''Literature/{{IT}}''. Being the only member of the Lucky Seven who stayed in Derry, and therefore the only one who remembers anything at all about what happened when they were kids, Mike is something of an exposition god in the book. Not only does he provide exposition to his friends little by little, his journal entries provide exposition as to the history of It, and whenever another character gets to do some expositioning they generally turn to Mike and ask if whatever they just stated is correct. Interestingly enough, it works. Contagious amnesia can apparently be a wonderful exposition tool so long as someone is immune.
* ''Literature/LookingBackward'': Dr. Leete. He explains to Julian West everything that's changed so he'll adjust into the future US.

* In ''Manga/MurasakiiroNoQualia'', Tenjou is the one who introduces most of the [[UsefulNotes/QuantumPhysics physics concepts]] relevant for the story, which is understandable considering her position.

* Justified with [[PosthumousCharacter Atsuko]] in ''LightNovel/MyNextLifeAsAVillainessAllRoutesLeadToDoom''. Given that the story is taking place in the world of ''[[FictionalVideoGame Fortune Lover]]'' (a game that she's played to 100% completion), she's able to fill in details for routes that Catarina didn't get the chance to play via flashbacks to her giving spoilers. [[spoiler:Even her BigDamnHeroes moment boils down to her spirit giving Catarina spoilers about the secret route.]]

* In ''Series/DoctorWho'', the Doctor always has a traveling companion from modern Earth who would be in the dark if the Doctor didn't explain everything. That seems to be the main function of the cohort, a "Watson" to his "Sherlock".

** In ''ComicBook/HelOnEarth'', ComicBook/{{Superboy}} notes how Franchise/{{Superman}} tends to [[CasualDangerDialog lecture him during situations]] in. Superman claims he doesn't lecture, he [[InsistentTerminology merely explains]].
