-->-- ''Series/CriminalMinds'', "Derailed"

Some characters just seem to know a little of everything. It doesn't matter what the subject is, they can rattle off a couple of facts on the subject. They might not have much depth of knowledge, but they certainly have breadth. The possessor of this knowledge doesn't have to be alive in the traditional sense. Robots, [=AIs=], sentient books and the like count as well.

Sometimes these little tidbits can serve as a ChekhovsGun when the information comes in handy later, sometimes they'll provide just the right details needed right then to solve a problem, and sometimes they'll just sound like {{Non Sequitur}}s. This trope is often used to make a [[TheSmartGuy character's intelligence]] more than just an InformedAbility.

'''Note:''' This isn't for characters who think they know everything. They need to actually have real, accurate knowledge. It also is not for characters who just know everything about one subject, such as history, maths or automotive repair. They need to have a little knowledge about everything.

[[folder: Anime and Manga ]]

* Miyuki Takara of ''Anime/LuckyStar'': Her ability to always have information relevant to the subject of conversation earned her the FanNickname Mi[[{{Wiki/Wikipedia}} wiki]].
* [[SpellMyNameWithAnS Shezka]] from ''Manga/FullmetalAlchemist'' remembers every little thing she reads, logically resulting in Encyclopedic Knowledge being mixed with a good dose of Human Data Storage.
* Tsubasa Hanekawa from ''LightNovel/{{Bakemonogatari}}'' [[CatchPhrase doesn't know "everything," she just knows what she knows]]. Which seems to be nearly everything--not surprising of the top student and class rep.


[[folder: Comic Books ]]

* The Devil's Dictionary in ''ComicBook/RequiemVampireKnight'' qualifies, but then, he's a ''dictionary demon''...
* Franchise/{{Batman}} is often presented this way, particularly when used in a team environment.
* [[http://www.toonopedia.com/geniusj.htm Genius Jones]]: A boy who was stranded on an island for several years with a library's worth of books he memorized. After being rescued, he would use his knowledge to solve mysteries for a dime apiece.
* ''ComicBook/{{Fables}}'' has an odd example in Bufkin the [[Literature/TheWonderfulWizardOfOz flying monkey]]; he is the librarian of the vast [[EldritchLocation Business Office]] and can perfectly remember where every book is stored and everything he's ever read (and he reads a lot). However, he's extremely goofy and generally lacking in foresight, self-control, and social graces (a RunningGag is that he throws poo at people and needs to be reminded that his fecal matter is ''not'' an appropriate topic of conversation). Consequently, he's comic relief until he ends up trapped in the Business Office with Baba Yaga, her three OneManArmy henchmen and an escaped Djinn, at which time BewareTheSillyOnes comes into full effect.


[[folder: Film ]]

* In the Disney movie ''Disney/TheComputerWoreTennisShoes'', a college student gets all the knowledge contained in a computer's data banks (mostly filled with educational material) and represents his school in a ''College Bowl'' type competition. What he doesn't realize is that the computer also had a criminal organization's records of its illegal activities. HilarityEnsues.
* In ''WesternAnimation/KungFuPanda'', Po has an impressive knowledge of martial arts lore and philosophy, although [[WesternAnimation/KungFuPandaLegendsOfAwesomeness the TV series]] has him realizing that there is far more to learn.


[[folder: Literature ]]

* Literature/EncyclopediaBrown got his nickname by knowing so much about so many subjects that he was like a walking encyclopedia.
* Jacques Paganel in Creator/JulesVerne's ''Literature/InSearchOfTheCastaways''.
* In ''Literature/TheDresdenFiles'', the girl Harry calls "Ivy" is The Archive of all magical knowledge. If you write it down, she can see it.
* DV-9 in ''Literature/GalaxyOfFear''. Well, he ''is'' a research droid.
* Ignatius Prindable in ''Literature/DontCallMeIshmael'' is mostly interested in math and biology, but he tends to rattle off random facts about all kinds of different topics even if they have nothing to do with what the characters are talking about.
* Kazuhiko Kozuka "[[RedBaron of Socials and Sciences]]" in ''Literature/TanteiTeamKZJikenNote'' has the tendency to provide exposition on bits of factoid.
* Averted by Literature/SherlockHolmes, who specifically warns against storing vast amounts of useless knowledge, comparing it to a man buying planks of any size rather than those that will fit into the lumberroom. However, his knowledge comes across as this trope instead as there is always some link to criminology.


[[folder: Live Action TV ]]

* ''Series/{{Bones}}'' has Mr. Nigel-Murray who spouts off random facts as a way to keep himself focused.
* ''Series/JohnDoe'' has this UpToEleven, for supernatural reasons. Supposedly he is actually omniscient, but in practice his knowledge is limited to things that could be learned via research.
* In ''Series/{{Chuck}}'', the Intersect acts as this with government information, martial arts, hacking skill and linguistic abilities, to name a few fields.
* Sheldon from ''Series/TheBigBangTheory'' knows just about everything (as long as it isn't pop culture related, or about driving, or about social interaction), and does not hesitate to point it out, whether he is asked or not.
** He at least likes to think he knows everything, but he's shown clear faults in the field of Biology and such. It's implied that he gets most of the non-Physics related information off the Internet.
* Reid from ''Series/CriminalMinds'' does this, to the point of irritating the other characters. Because he reads quickly and often, has an eidetic memory, and is particularly fond of statistics, he simply pulls from his memory whatever statistic the situation calls for. Morgan even [[LampshadeHanging lampshades]] it in the episode "Derailed":
-->'''Reid''': Tardive dyskinesia.
-->'''Morgan''': Once more for those of us who don't have an encyclopedic memory?
* ''Series/{{CSI}}''. Two words: Gil Grissom. Ray and DB have gotten into the act a little bit since Grissom's departure, but they can't compete with Gil.
* Mac from ''Series/{{CSINY}}'' is another case. It doesn't matter what unusual hobby the victim had, Mac is well versed in it.
* ''Series/{{Cheers}}'' has Cliff Clavin, who mixes this trope with LittleKnownFacts and a dash of FeigningIntelligence, leaving everyone never quite sure whether [[TheCuckoolanderWasRight the latest bit of trivia is one of the accurate facts or not]].
* ''Series/BarneyMiller'': Detective Arthur Dietrich can always be counted on to know more than anyone else in the precinct about any obscure topic.


[[folder: Radio ]]

* Vivian Stanshall's ''RawlinsonEnd'' stories feature Reg Smeeton, whose encyclopedic knowledge of trivia is triggered by word association, e.g., when he hears the word "shrewd", he rattles off facts about shrews. Of course, nobody ever listens to him, and his inner monologue consists of complex chains of association that all lead to the conclusion "me = zero". This is true in the LP, film and literary versions as well.


[[folder: Tabletop RPG ]]

* The ''TabletopGame/NewWorldOfDarkness'' has a four dot merit [[TropeNamer Encyclopaedic Knowledge]] that gives characters this ability.
* Savants in ''TabletopGame/{{Warhammer 40000}}'' tend to be characterised like this, especially in the related novels.


[[folder: Video Games ]]

* In the ''Franchise/{{Castlevania}}'' series, CuteWitch [[VideoGame/CastlevaniaPortraitOfRuin Charlotte Aulin]] is this, most likely as a counterbalance to (a) the more "rely-on-gut-feeling" Jonathan and (b) her own [[JustAKid young age of 16 years]] (this is Charlotte's BerserkButton, by the way). The only subversion is that she really ''is'' a BrainyBrunette with a veritable cornucopia of knowledge on most subjects (to the point that in the final battle, she expresses surprise that [[spoiler:[[DualBoss Death is actually teaming up with Dracula]]]] since she never read about it in her books).


[[folder: Web Original ]]

* The Hermit, one of the TAROT villains from the ''Roleplay/GlobalGuardiansPBEMUniverse'', retains a perfect memory of everything he ever experienced from the time of his childbirth, and is a voracious reader. He's also one of the world's smartest people, allowing him to put his Encyclopedic Knowledge of ''everything'' [[CrazyPrepared to use against his opponents]]. He's a villain the heroes hate going up against, simply because he's so annoyingly effective.
* Noriko Null from ''Literature/BeyondTheImpossible''. In addition to being superhumanly smart, every single information known to mankind has been uploaded into her brain. And every new information is upgraded about once a month, provided she's on the planet.
* While the hosts of Podcast/FatFrenchAndFabulous trade off who researches and presents the week's topic, both seem to be able to reference and explain highly-specific concepts off the top of their heads, such as Pigovian taxes and cognatic primogeniture.


[[folder: Western Animation ]]

* In every episode of ''WesternAnimation/TheMagicSchoolBus'', Dorothy Ann provides information about the topic of the day from her research.
** Though since she IS [[ChildProdigy only 9 or 10]], she occasionally just reads it out of whatever book she has currently pulled out of her shoulder bag.
* There is also "Mr. Know-it-all", a recurring sketch from one of the ''WesternAnimation/RockyAndBullwinkle'' series. Actually a parody, as Bullwinkle (who plays Mr. Know-it-all) has knowledge that is [[TheDitz less than encyclopedic]].
** A more straightforward example is Mr. Peabody from the "Peabody's Improbable History" segments of the same show.
* Tom on ''WesternAnimation/TheAmazingChanAndTheChanClan'', most notably in episodes 14 and 16.
* The ''WesternAnimation/{{Transformers}}'' have the Autobot Rewind, whose entire personality shtick is that he loves collecting trivial factoids about anything and everything.
