!!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 occurrences. 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, he becomes an animated character and ventures on a journey through the library's fiction section to find the exit.
----
* {{Adorkable}}: A very nervous but charming nerdy kid through and through.
* BadassBookworm: Becomes this over the course of the film.
* {{Bookworm}}: But only of fact-based books, at first.
* CallingCard: His library card.
* CowardlyLion: Easily frightened and cautious about everything, who overcomes his fears to become a better person.
* EverythingTryingToKillYou: He believes everything is trying to hurt him in some shape or form. This becomes quite real in the animated world.
* FalseCrucible: [[spoiler:It turns out everything that Richard went through was just a test by the Pagemaster. Needless to say, Richard [[WhatTheHellHero 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. Now who was it who dropped the bucket in the first place?
* KidHero: A contemporary take on the standard fantasy hero.
* 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, Richard is 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: See LogicalFallacies above. In this case, of course, his precision is far more ludicrous than is average for this trope.
* NerdGlasses: Round, brown spectacles.
* TrappedInAnotherWorld: After he slips, falls and gets knocked out.
* TookALevelInBadass: [[spoiler:Enough to go up against a ''dragon'' to protect his new friends.]]
* WhyDidItHaveToBeSnakes: His flaw is that he's afraid of pretty much everything.

!!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: A long white one that resembles book pages.
* GuileHero: It's revealed that he deliberately sent Richard on his dangerous journey so he could conquer his phobias.
* MagicStaff: Shaped in the form of a scroll.
* PetTheDog: 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: Stylised to resemble wrapped up paper.
* SecretTestOfCharacter: His method to help Richard overcome his fears.
* WhatTheHellHero: Richard gives him a grand chewing-out after realizing his entire ordeal was just the Pagemaster's test.

!!Mr. Dewey
-->'''Played by:''' Creator/ChristopherLloyd

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: Has a very distinctive pointed beard.
* {{Bookworm}}: This is clear based on his enthusiasm to give Richard a book.
* InformedAbility: "I have a talent at guessing what people need."
* MagicalLibrary: In his eyes, the library is a magical place. It may or may not actually be magical, even though it seems Richard's adventures were AllJustADream.
* MeaningfulName: He's named after the ''Dewey'' Decimal System which is used to organize books in libraries.
* 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: No one seems to come to the library anymore.

!!Adventure
-->'''Played by:''' Creator/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: He's a talking book with arms and legs.
* BadassBoast: [[WroteTheBook "I wrote the book on sailing. In fact, I am the book on sailing!"]]
* ButtMonkey: 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.
* EarnYourHappyEnding: Follows Richard in the hopes of being checked out as a library book.
* EyepatchOfPower: Wears an eyepatch, although he still has both eyes intact. He wears it because [[RuleOfCool 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: He is a pirate after all.
* 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 voiced by Creator/PatrickStewart after all.
* MasterSwordsman: Claims to be, but doesn't get much chance to show off his skills since he is the ButtMonkey of the film.
* OwMyBodyPart: "Oooh! Me binding!"
* {{Pirate}}: A very traditional role. Aside from being a talking book.
* PortalBook: Contains a number of pirate-related weaponry within his pages.
* SensitiveGuyAndManlyMan: Adventure is the 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]].
* TalkLikeAPirate: You'd better believe it, mateys.
* UngratefulBastard: Being the [[SmallNameBigEgo 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!]]
* UnusualEuphemism: To Fantasy: "How'd you like to curl up with a good book?"

!!Fantasy
--> '''Played by:''' Creator/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: A talking book with a fairy motif.
* DeadpanSnarker: Has her moments.
-->'''Fantasy:''' (regarding Adventure) You know that short story?
-->'''Richard:''' Yeah, he's Adventure.
-->'''Fantasy:''' Honey, that's what they all say.
-->'''Adventure:''' I heard that! I'll have you know I'm a classic!
-->'''Fantasy:''' Mmm-hmmm...a classic misprint!
* FairyCompanion: Accompanies Richard on his journey.
* FairyGodmother: Acts as one to Richard and claims to grant wishes.
* FishOutOfWater: She was mis-shelved and is [[GenreBlindness clueless to the horror genre]].
* MagicCarpet: Has Horror rip out one of her pages and transforms it into a flying carpet.
* MagicWand: She seems to have a bit of a faulty one but gets stronger when in the fantasy section.
* PortalBook: Able to pull fantasy-related objects from her pages like a flying carpet.
* SassyBlackWoman: Well she is voiced by Whoopi Goldberg.
* ShipTease: With Adventure, though she doesn't seem to want it.
* TheSmurfettePrinciple: The only woman in Richard's group.
* VerbalTic: "Mmm-hmmm."

!!Horror
--> '''Played by:''' Creator/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 mis-shelved in life and wants to gain a happy ending.
* AnimateInanimateObject: A talking book.
* ChekhovsGunman: Horror discovers he can float after the group is separated by Moby Dick.
* CowardlyLion / LovableCoward: Similar to Richard, he is easily frightened despite coming from the horror section of the library, but becomes braver over time.
* CuteMonster: In the eyes of Fantasy.
* DynamicEntry: Swings into battle like Tarzan and knocks out several pirates upon landing.
* EarnYourHappyEnding: All he wants is to be checked out and be happy.
* FallingIntoHisArms: A subverted version. Horror is knocked out of a bell tower and lands in Richard's arms.
* FriendToAllLivingThings: Horror is the most gentle of characters compared to the hot-headed Adventure and Fantasy, and wouldn't hurt a fly.
* TheGrotesque: Horror is described as a "hunchbook" and is based on [[Literature/TheHunchbackOfNotreDame Quasimodo]]. He has a misshapen spine and torn features. Also has elements of Igor, referring to Richard as his "master".
* IJustWantToHaveFriends: Too friendly and kind for the horror section, Horror just wants to have friends and a better existence.
* TheKlutz: A bit clumsy and accident prone at times. He accidentally knocks Fantasy's wand out of her hand and it is eaten by the dragon, causing it to gain extra firepower and fry the flying carpet they are on.
* SensitiveGuyAndManlyMan: The relationship between Horror and Adventure. Adventure is mostly mean and insulting towards Horror, and angrily chews out Horror when he comments that he could be like him (but mostly because his pride was damaged because Fantasy and Horror rescued Richard from the pirates). The two get along better after Adventure mistakes Horror for being dead.
* TechnicallyASmile: Gives a lopsided smile upon meeting Richard.
-->'''Fantasy:''' Look, he's smiling.
-->''(Horror gives a weird smile)''
-->'''Richard:''' That's a smile?

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

The first literary character met in the film. A gentlemanly MadScientist, Dr. Jekyll creates a potion to [[EnemyWithin split apart his dark side]], only to transform into the AxCrazy Mr. Hyde.
----
* AmbitionIsEvil: Wants to help mankind, but ends up becoming a full-on psychopath.
* AxCrazy: Mr. Hyde immediately starts laughing like a lunatic and attacks Richrd and his friends with a cane.
* BigBad: While not in the film, 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 brief 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, but he appears at the film's end, revealed to be part of the Pagemaster's SecretTestOfCharacter.
* FallingChandelierOfDoom: Horror drops a chandelier on Mr. Hyde. It misses but causes Hyde to fall through a hole in the floor and dangle from a chain. Fantasy breaks the chain like a blowtorch, and we hear Mr. Hyde fall to his apparent doom. He survives and transforms back into Dr. Jekyll at the end of the film.
* MadScientist: As in the novel, Dr. Jekyll is an ambitious scientist hoping to help mankind and rid himself of his own darkness. However, he makes a formula which instead backfires and turns him into Mr. Hyde.
* MessengerOfDoom: Dr. Jekyll informs Richard that he is in grave danger for entering his house.
-->'''Dr. Jekyll:''' My boy, I derive no pleasure in telling you, that you are in extreme danger.
-->'''Richard:''' Danger!
-->'''Dr. Jekyll:''' Even as we speak. In this very room waiting to strike are the forces of evil. Every man is possessed of both good and evil. But enough of that, [[MoodDissonance anyone care for a drink?]]
* NightmareFace: Mr. Hyde's is one to remember.
* PainfulTransformation: The transformation is brief but pretty terrifying. Dr. Jekyll screams in agony as his body reacts to his potion, then he undergoes some body horror before becoming Mr. Hyde.
* 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 dead-set on killing Moby Dick.
----
* AmbitionIsEvil: Wants to kill Moby as an act of revenge.
* AxCrazy: One reason why Adventure likes him.
* [[DroppedABridgeOnHim Dropped A Whale On Him]]: Tries to kill Moby Dick with a spear, only to have the whale leap out of the water and sink his ship.
* FatherNeptune: Shown to be a veteran sailor and hunter.
* GoshDangItToHeck: Subverted. His speech before attacking Moby is taken from the book.
* IncomingHam: "Thar she blows!"
* LargeHam: Taken from the source material.
* SpearCarrier: Little more than a OneSceneWonder, Captain Ahab sails into the ocean and tries to slay Moby Dick. It doesn't work.

!!Long John Silver
--> '''Played by:''' Creator/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.
----
* AffablyEvil: Quite polite towards Richard, wishing to employ him as a cabin boy, and departs from the island when Richard threatens him with a sword.
* CoolSword: Has one as a pirate should.
* TheDreaded: Adventure describes him as this.
* HandicappedBadass: Needs to use a crutch in order to walk, but is very ruthless and determined.
* JerkWithAHeartOfGold: Like in the book, while he is a villain nonetheless, he is actually quite nice to Richard, reflecting how he treated Jim Hawkins in the original story. In the climax, he congratulates Richard on facing his fears.
* LargeHam: "There she be, mateys! Treasure Island!"
* TheMutiny: His crew try to pull this on him when they cannot find any treasure, only for Fantasy and Horror to arrive to rescue their friends.
* PirateParrot: Accompanied by a scrawny parrot.
* TalkLikeAPirate: But of course.
* WellDoneSonGuy: Gives Richard his congratulations.
-->'''Long John''': You've pirate stuff in ya, lad.

!!The Dragon

The final obstacle between Richard and the exit. An enormous fire breathing dragon who attacks Richard and his friends after they wake him up.
----
* BreathWeapon: Can breathe fire. Gets a little power boost after eating Fantasy's wand.
* GiantFlyer: Flies on giant bat wings.
* OurDragonsAreDifferent: Your standard fire-breathing dragon...that also materialises in a melted rotunda artwork to chase Richard.
* RibcageStomach: And contains a number of children's books and molten lava!
* ThatsNoMoon: Mistaken for a cave until Adventure chops one of its fangs off, awakening the dragon.
* WhenTreesAttack: Gets paralyzed when a beanstalk grows out of its mouth.
