%%* ChildrenAreInnocent

The {{Deuteragonist}} of the story, Sheeta is a young girl who used to live on a farm with her grandmother. Although living an ordinary life, she secretly holds a mysterious amulet connected to the legendary city of Laputa, making her a target of the army and sky-pirates wishing to locate the city for themselves. Luckily, she meets up with Pazu, who helps her make her own search.

* BondingOverMissingParents: With Pazu, obviously.
* BreakHisHeartToSaveHim: Sheeta makes a deal with Muska to save Pazu's life. It involves telling Pazu to return to his home town and forget about her and Laputa, which he reluctantly does. [[GenreSavvy Until Dola points out the trope,]] at which point he opts to rescue her.
* BrokenBird: She's a little cold and hesitant around other people after losing her grandmother and being kidnapped by the military, not to mention everything that happens afterwards.

* ActionMom: All of the other pirates call her mom, likely all being her actual sons--she's still a badass captain though.
* AntiHero: While still a pirate and reckless with other people's safety to get what she wants, she and her sons are not nearly as bad as [[ArmiesAreEvil the actual military.]]
* ApronMatron: She keeps all her 'boys' close at hand to serve as pirate crew. Not that most of them can be trusted with even the simplest tasks on their own.

* [[spoiler:EnemyMine: Teams up with Pazu and Sheeta because of their mutual enemy, Muska, as well as their mutual interest/need for Laputa.]]

* GirlishPigtails: A trait she shares with Sheeta, which is why she empathizes most that [[spoiler:Muska shot Sheeta's pigtails off.]]
* GoodIsNotSoft: She's gruff, doesn't go out of her way to help other people, and steals whatever she can get her hands on, but she is a good person at heart.

* IWasQuiteALooker: Take a look at the photograph of her inside her personal quarters. She looks exactly like a red-haired Sheeta.
* JerkWithAHeartOfGold: Pazu even points it out, she isn't as mean as she pretends to be.
* LargeHam: Very loud and very upfront. At one points she is even eating a very large ham, which would count as a LampshadeHanging had this film been made later. Cloris Leachman's voice acting in the Disney dub takes it UpToEleven.

!Colonel Muska
[[caption-width-right:350:"Laputa will live. I will return it to life! Laputa's power is the dream of all mankind!"]]

A colonel who acts as a covert operative in the military; he takes control of the government's effort to discover Laputa. He's the movie's BigBad and another person trying to use Sheeta to find the city, having lead the soldiers who kidnapped her before the start of the plot. Unbeknownst to the rest of the military, he seems to have his own motives for finding Laputa.

* AnOfferYouCantRefuse: Makes one to Sheeta. Albeit with his FauxAffablyEvil facade still going, but the threat is still there; either she helps them find Laputa or they will kill Pazu.

* EvilLaugh: Especially with Mark Hamill as his voice.
* EvilPlan: Using [[KillSat Laputa]] to [[TakeOverTheWorld rule the earth once again]]. Which is unfortunately an entirely plausible plan due to the enormous capabilities of the Laputean machinery and technology.
* FantasticNuke: How he uses Laputa, especially after he gains control of the (usually benevolent) robots.
* FauxAffablyEvil: As Sheeta's captor, he is quite corteous and polite, also toward Pazu. Once he gains control of [[spoiler:Laputa]], however, he sheds the facade.
* ImprobableAimingSkills: "Your ears are next", he tells Sheeta after shooting off her pigtails.
* [[spoiler:[[KarmicDeath Karmic]] DisneyVillainDeath: He's blinded and stumbles around the crumbling Laputean floors. We don't see it, but he obviously dies falling down with the palace floors.]]
* [[spoiler:LongLostRelative: In a dark version of this trope, Muska is one to Sheeta.]]
%%* TheNeidermeyer

* PersonOfMassDestruction: [[spoiler:When he takes over control of Laputa.]]
* [[spoiler:RoyalBlood: Like Sheeta, he is the heir to the Laputean throne. Although it's likely he's from a lesser branch, considering it was Sheeta's family that inherited the royal crystal.]]

!General Muoro

A general in the army who is one of the leaders behind the effort to find Laputa. He works with Muska only reluctantly, suspicious of his covert operations.

->'''Voiced by''': Creator/IchiroNagai (JP), Mike Reynolds (US '89), Creator/JimCummings (US '03), Björn Gedda (SV)
* ArmiesAreEvil: He's brutal and even advocates torturing Sheeta to get her to show them how to use the amulet. Despite all that, [[spoiler:he's not as bad as Muska.]]
%%* [[spoiler:DisneyVillainDeath]]
* EvenEvilHasStandards: [[spoiler:Probably led to his decision to try and kill Muska.]]
* EvilIsHammy: Not as much as Hamill and Leachman in the Disney dub, but Jim Cummings does get to have fun with the character in places.
* FatBastard: Fat and a cruel general.
%%* GlorySeeker
* TooDumbToLive: [[spoiler:Shooting bullets at a projected image of Muska.]]

!Uncle Pom

An old man living in the caves beneath the city. He possesses knowledge of Laputa and its resources, such as the aetherium that helps it to fly.

->'''Voiced by''': Fujio Tokita (JP), Ed Mannix (US '89), Richard Dysart (US '03), Johan Hedenberg (SV)
* ChekhovsGunman: He is the first one to make the kids realize where Sheeta is really from.
* CoolOldGuy: Pazu seems to think so.
* HermitGuru: But he lives underneath the ground instead of a cave or other secluded area.

!Dola's sons

Dola's crew, composed almost certainly of all her sons. While occasionally bumbling and incompetent, they're all incredibly loyal to her and a formidable force in numbers.

%%* {{Big Eater}}s
* {{Boisterous Bruiser}}s: Especially the one that can make [[CrowningMomentOfFunny his shirt explode]].
* {{Bunny Ears Lawyer}}s: Some of them are pretty competent in spite of their goofiness.
* TheDitz: Some are a little better about this than others--the ones with beards are the goofiest.
* EvenBadMenLoveTheirMamas: "All good pirates listen to their mom."
* FiveTokenBand: There are more than five, but they fit the trope. Some of them are [[TokenMinority black-skinned]], others have distinctly Asian features. Most of the other characters look Caucasian (which figures since the movie is set in a fantasy version of Wales). There is some debate as to whether the different-looking pirates are crew instead of family, Dola's adopted children or her children by different fathers. They all call her Mom.
%%* JabbaTableManners
* {{Large Ham}}s: Mandy Patinkin, Mike [=McShane=], and Andy Dick were clearly having a lot of fun with their roles.
* [[ManChild Man Children]]
%%* ThePiratesWhoDontDoAnything
* PunchClockVillain: In the first act.
