!!Richard Tyler
-->'''Played by:''' Macaulay Culkin

A young boy who has a severe phobia of everything and lives a life based on the statistics of accident occurences. Sent out to the hardware store by his concerned father, Richard gets caught in a storm and takes shelter in a library. Knocking himself out by slipping on a wet floor, Richard becomes an animated character and ventures on a journey through the library's fiction section to find the exit.
* {{Adorkable}}
* {{Bookworm}}: But only of fact-based books at first.
** BadassBookworm: Becomes this over the course of the film.
* CallingCard: His library card.
* CowardlyLion
* CuteBookworm
* EverythingTryingToKillYou: He believes everything is trying to hurt him in some shape or form. This becomes quite real in the animated world.
* FalseCrucible: [[spoiler: Turns out everything Richard went through was just a test by the Pagemaster. Needless to say, Richard does not take it very well.]]
* GenreBlindness: He apparently has read little to no literature in his life.
* HypocriticalHumor: When his father falls from the treehouse after Richard drops a bucket of nails on his head, Richard tells his father he cannot argue with statistics. And who was it that dropped the bucket in the first place?
* KidHero
* KnightInShiningArmor: To battle the dragon.
* LogicalFallacies: Richard follows his life based on the statistics of how many accidents can occur in just about every scenario. As the main page points out - "8% of all household accidents involve ladders. Another 3% involve trees. We're looking at 11% probability here". First, he's ignoring some overlap between the 8% and the 3%. Secondly he's assuming that an accident will happen, in which case the probability that it involves ladders is 8%, but that doesn't tell us anything about the chances that this specific ladder-climbing event will lead to an accident. What he needs is a statistic in the form of "X% of the time somebody climbs a ladder, they have an accident" rather than "X% of all accidents involve ladders."
** LudicrousPrecision
* NerdGlasses
* TrappedInAnotherWorld
* TookALevelInBadass: [[spoiler: Enough to go up against a ''dragon'' to protect his new friends.]]
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Everything?]]: His FatalFlaw.

!!The Pagemaster
-->'''Played by:''' Creator/ChristopherLloyd

The titular character and guardian of literature and reading. He sends Richard on his journey to find the exit, hoping he will overcome his fears. Possibly related to or is Mr. Dewey.
* BadassBookworm: His clothes, his staff and even his beard all seem to be made out of pages.
* BadassBeard
* GuileHero: [[spoiler: Revealed he deliberately sent Richard on his dangerous journey so he could conquer his phobias.]]
* MagicStaff: Shaped in the form of a scroll.
* PetTheDog: [[spoiler: Sends Richard back to his own world after Richard successfully overcomes his fears.]]
* PhysicalGod: He's implied to be something like this in his world, judging by how the three books react to him.
* RobeAndWizardHat
* WhatTheHellHero: [[spoiler: Richard gives him a grand chewing-out after realising his entire ordeal was just the Pagemaster's SecretTestOfCharacter.]]

!!Mr. Dewey
-->'''Played by:''' Christopher Lloyd

A friendly but mysterious librarian who gives Richard his library card. It appears he does not get many visitors to the library and is quite enthusiastic at getting people to check out the books.
* BadassBeard
* BookWorm: Clearly based on his enthusiasm to give Richard a book.
* CoolOldGuy
* InformedAbility: "I have a talent at guessing what people need."
* MagicalLibrary
* MeaningfulName: After the Dewey Decimal System which is used to organise books in a library.
* ScaryLibrarian: Subverted, since he only wants people to check out books.
* SecretKeeper: Seems to know what happened to Richard, but might actually be the Pagemaster.
** It's possible that he knows of the events that happen, thus why he allows Richard to take Horror, Adventure and Fantasy.
* SpookySilentLibrary

!!Adventure
-->'''Played by:''' PatrickStewart

A talking book who is an adventurous, daring pirate. He meets Richard after he crashes a book cart into his shelf, Adventure spotting his library card and accompanies Richard to find the exit so he can be checked out.
* AffectionateNickname: Calls Richard "Matey".
* AnimateInanimateObject
* BadAss
* BadassBoast: [[WroteTheBook "I wrote the book on sailing. In fact, I am the book on sailing!"]]
* ButtMonkey / HumiliationConga: Let's see - he is smashed by a book cart, falls off the top of a book shelf to the floor, drenched by a wive, looted by fellow pirates, tossed into a treasure chest during his only chance at a swordfight, enchanted to wear a dress and wig, and fried by a dragon.
* CoolSword
* EarnYourHappyEnding
* EyepatchOfPower: Wears an eyepatch, although he still has both eyes intact. He wears it because it makes him look good.
* ForcefulKiss: Pulls this on Fantasy in a romantic moment and gets smacked for it.
* GenreSavvy: In the adventure section and horror section. Not so much in the fantasy section.
* HandicappedBadass: Has a hook and a peg leg, but is still pretty awesome.
* HookHand
* JerkWithAHeartOfGold: While he often argues with Fantasy and mocks Horror, he is a good man at heart and ultimately feels guilty for mistreating Horror.
* LargeHam: Well, he is a pirate and played by PatrickStewart after all.
* MasterSwordsman
* OwMyBodyPart: "Oooh! Me binding!"
* {{Pirate}}: A very traditional role. Aside from being a talking book.
** TalkLikeAPirate
* SensitiveGuyAndManlyMan: Manly Man to Horror's Sensitive Guy.
* ShipTease: With Fantasy. They spend a good deal of the film bantering, before he pulls a surprise kiss on her near the end. [[ArmorPiercingSlap She doesn't take too kindly to that.]]
** UnusualEuphemism: "How'd you like to curl up with a good book?"
* UngratefulBastard: Being the prideful braggard that he is, he certainly shows no gratitude when Horror and Fantasy help him and Richard fend off the pirates, especially since he spent the entire fight trapped in a chest right when he saw a good opportunity to have a good battle.
-->'''Adventure:''' I coulda taken the lot of 'em with one hand tied behind me back! ''(storms off)''
-->'''Richard:''' It's just his way of saying thanks.
-->'''Horror:''' ''(grabs a sword and puts on a bandana)'' [[ComicallyMissingThePoint You're welcome!]]

!!Fantasy
--> '''Played by:''' WhoopiGoldberg

A sassy book from the fantasy section. Mis-shelved, Fantasy meets Richard by chance and agrees to guide him through the library in exchange for checking her out.
* AnimateInanimateObject
* BenevolentGenie: She grants wishes, despite being a fairy.
* DeadpanSnarker
* FairyCompanion
* FishOutOfWater: She was mishelved and is [[GenreBlindness clueless to the horror genre]].
* MagicWand: She seems to have a bit of a faulty one. [[spoiler: It gets better once she's closer to her home turf.]]
* [[SassyBlackWoman Sassy Pink Book]]
* ShipTease: With Adventure, though she doesn't seem to want it.
* TheSmurfettePrinciple
* VerbalTic: "Mmm-hmmm".
* [[YouGottaHaveBlueHair You Gotta Have Purple Hair]]

!!Horror
--> '''Played by:''' FrankWelker

The third of Richard's book companions. Horror is a misshaped book who Richard meets in the horror section, and they quickly bond due to their timid nature, but both learn to become braver over time.
* AllThereInTheManual: WordOfGod states that Horror was created with a misshapen spine, and his parents were an encyclopedia and a paperback book. As a result, Horror feels he has been mishelved in life and wants to gain a happy ending.
* AnimateInanimateObject
* CowardlyLion

!!Dr. Jekyll/Mr. Hyde
--> '''Played by:''' LeonardNimoy

The first literary character met in the film. According to the source material, Jekyll has created a potion (which here looks like a cocktail martini) to separate one's darkside from their body. Things didn't go as planned and his darkside took over as Mr. Hyde.
* AffablyEvil: Jekyll is most certainly affable, Hyde is full on evil.
* AmbitionIsEvil: Wants to help mankind, but ends up becoming a full-on psychopath.
* AntiVillain: Jekyll is this, Hyde is anything but.
* AxCrazy: It comes to mind whether or not Hyde was partially influenced by JackTheRipper, another murderer of the same vintage.
* BigBad: While not in the film, unfortunately. Hyde becomes the Big Bad in the PC game.
* BodyHorror: Like in the book he was from, Jekyll completely changes when he becomes Hyde. We get a breif glimpse of this when he grabs Richard and his hand begins to get hairier.
* DisneyVillainDeath: Overlaps with HesJustHiding. We never find out Hyde's ultimate fate after falling through the hole in his floor.
* MadScientist
* NightmareFuelStationAttendant
* PainfulTransformation
* SlasherSmile: Again, Hyde.
* SuperpoweredEvilSide: He just needs to drink the potion in order to become this.

!!Captain Ahab
--> '''Played by:''' George Hearn

The second literary character in the film. Ahab, like in the book he was from, is deadset on killing Moby Dick.

* AmbitionIsEvil: Wants to kill Moby as an act of revenge.
* AxCrazy: One reason why Adventure likes him.
* BadassGrandpa
* FatherNeptune
* GoshDangItToHeck: Subverted. His speech before attacking Moby is taken from the book.
* IncomingHam: "Thar she blows!"
* LargeHam: Taken from the source material.
* OneSceneWonder: And a rather frightening one at it.

!!Long John Silver
--> '''Played by: JimCummings'''

The third literary character met in the film. Like in the book, Long John has rallied a band of pirates to find Flint's trove on TreasureIsland.

* BadAss
** HandicappedBadass: Neads to use a crutch in order to walk.
* CoolSword
* JerkWithAHeartOfGold: Like in the book, while he is a villain nonetheless, he is actually quite nice to Richard, reflecting how he treated Jim in the original story.
* LargeHam: Well, he is a pirate and played by JimCummings after all.
* MasterSwordsman
* Pirate
* TalkLikeAPirate
* WellDoneSonGuy: Gives Richard his congratulations.
-->'''Long John''': You've pirate stuff in ya, lad.
