- Adorably Precocious Child: He's a skilled mechanic despite his age, earning him the respect of the Dola gang's mechanic.

- Children Are Innocent: He is quite precocious for his age, but also quite naturally ignorant of many things.
- Chronic Hero Syndrome: In the climax, where he refuses to leave Sheeta alone even though it could mean a swift resolution of Muska's entire gamut. Muska plays him like a fiddle because of this.

- Generation Xerox: Not unlike his dad, he builds flying machines and has an obsession with Laputa.

- Action Mom: All of the other pirates call her mom, likely all being her actual sons—she's still a badass captain though.
- Anti-Hero: 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 the actual military.
- Apron Matron: 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.
- Big Bad Ensemble: At the beginning of the movie, Dola VS Muska. Until it becomes clear Dola is really a good guy.
- Boobs of Steel: She has remarkably large breasts.
- Braids of Action: Wears her hair this way.
- Cool Airship: Her ship.
- Cool Old Lady: She's a sky pirate, aged about 70.
- Defeat Means Friendship: Once Pazu manages to outrace Dola and her boys, she respects him enough to take him onto her crew.
- Drives Like Crazy: In the chase scene while in the automobile. Holy cow.
- Enemy Mine: Teams up with Pazu and Sheeta because of their mutual enemy, Muska, as well as their mutual interest/need for Laputa.
- Girlish Pigtails: A trait she shares with Sheeta, which is why she empathizes most that Muska shot Sheeta's pigtails off.
- Good Is Not Soft: 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.
- Insistent Terminology: She's a captain, not just Dola or "mom."
- I Was Quite a Looker: Take a look at the photograph of her inside her personal quarters. She looks exactly like a red-haired Sheeta.
- Jerk with a Heart of Gold: Pazu even points it out, she isn't as mean as she pretends to be.
- Large Ham: Very loud and very upfront. At one points she is even eating a very large ham, which would count as a Lampshade Hanging had this film been made later. Cloris Leachman's voice acting in the Disney dub takes it Up to Eleven.
- A Mother to Her Men: Quite literally, since she is their mother.
- Never Mess with Granny: She is one of the most capable and tough as nails adults in the film.
- Not in This for Your Revolution: She only wanted to loot Laputa.

- An Offer You Can't Refuse: Makes one to Sheeta. Albeit with his Faux Affably Evil facade still going, but the threat is still there; either she helps them find Laputa or they will kill Pazu.
- Ax-Crazy: By the end he is reduced to this, once subtlety isn't really a necessity.
- Big Bad: In case you hadn't figured it out.
- Drunk on the Dark Side: The massive violent episode he goes through after gaining control of Laputa's powers.
- Evil Is Hammy: Especially with Mark Hamill's hammy voice work.Muska: The same technology that kept Laputa airborne also made it A MAJOR POWER THAT ONCE DOMINATED THE ENTIRE planet.
- Evil Laugh: Especially with Mark Hamill as his voice.
- Evil Plan: Using Laputa to rule the earth once again. Which is unfortunately an entirely plausible plan due to the enormous capabilities of the Laputean machinery and technology.
- Fantastic Nuke: How he uses Laputa, especially after he gains control of the (usually benevolent) robots.
- Faux Affably Evil: As Sheeta's captor, he is quite corteous and polite, also toward Pazu. Once he gains control of Laputa, however, he sheds the facade.
- Improbable Aiming Skills: "Your ears are next", he tells Sheeta after shooting off her pigtails.
- Disney Villain Death: 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.
- Knight of Cerebus: A particularly notable case for a Hayao Miyazaki film. Colonel Muska has no comical traits, being a Faux Affably Evil government agent treated very seriously by the protagonists. But Muska gets much worse after he massacres an entire army that helped him conquer Laputa, laughing maniacally at their deaths.
- Long-Lost Relative: In a dark version of this trope, Muska is one to Sheeta.
- Meaningful Name: Musca is the Latin word for "fly", an insect often associated with the dead, which it feeds off of. Muska is obsessed with the long-dead civilization of Laputa.
- The Neidermeyer: Not openly as obnoxious as other examples but one of the most uncaring and disloyal towards his subordinates.
- Overly Long Name: His full name is RoMuska Palo Ul Laputa
- Overt Operative: He acts as one in the military, and has a higher authority over general Mouro.
- Person of Mass Destruction: When he takes over control of Laputa.
- Royal Blood: 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.
- Scary Shiny Glasses: Doubles as an example of Sinister Shades.
- Social Darwinist: Which means that he deems everyone else apart from himself as too weak to be worthy to live, even Sheeta who's also Laputian.
- Villainous Breakdown: Moments before the collapse of Laputa.
- Villain with Good Publicity: Having governmental ties and being above a General hierarchically is a good start.
- Would Hurt a Child: Toward Sheeta and Pazu.
- Yellow Eyes of Sneakiness: One of the hints that something's off about him.

- Armies Are Evil: He's brutal and even advocates torturing Sheeta to get her to show them how to use the amulet. Despite all that, he's still not as bad as Muska.
- Disney Villain Death:[[ An Asshole Victim along with many other soldiers.
- Even Evil Has Standards: Probably led to his decision to try and kill Muska.
- Evil Is Hammy: Not as much as Hamill and Leachman in the Disney dub, but Jim Cummings does get to have fun with the character in places.
- Fat Bastard: Fat and a cruel general.
- Glory Seeker: And he's easily distracted by glitter to see any further.
- Too Dumb to Live: Shooting bullets at a projected image of Muska.

- Cool Old Guy: Pazu seems to think so.
- Hermit Guru: But he lives underneath the ground instead of a cave or other secluded area.

- Big Eaters: They need much to sustain themselves after all.
- Boisterous Bruisers: Especially the one that can make his shirt explode.
- Bunny Ears Lawyers: Some of them are pretty competent in spite of their goofiness.
- The Ditz: Some are a little better about this than others—the ones with beards are the goofiest.
- Even Bad Men Love Their Mamas: "All good pirates listen to their mom."
- Five-Token Band: There are more than five, but they fit the trope. Some of them are 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.
- Jabba Table Manners: They don't bother with savoir vivre.
- Large Hams: Mandy Patinkin, Mike McShane, and Andy Dick were clearly having a lot of fun with their roles.
- Man Children
- Punch Clock Villain: In the first act.
