Characters: Treasure Planet
open/close all folders
Voiced by: Joseph Gordon-Levitt
- Adaptational Angst Upgrade: In the books, Jim's father died, but he grew up as a pretty well-adjusted teen. However, in the Disney adaptation, Jim's father just walked out on his family, causing Jim to have some serious issues leading to repeated incidents of delinquency and even failing school.
- Adaptational Villainy: A teenage delinquent variant. In the original novel, Jim was already polite young man who has no history with trouble; the Disney adaptation starts off with Jim as a repeat offender with failing grades and a bad attitude to authority.
- Adaptation Name Change: A minor case- the original Jim Hawkins was never stated to have a middle name, this one has the rather unusual "Pleiades", instead.
- Anti-Hero: He's not a bad kid, but he's surly, breaks traffic laws, and stresses his mother out a lot.
- Badass Adorable: Even though Jim is a teen, one can't help, but fall in love with the expression he makes.
- Badass Bookworm: Jim is known to be very intelligent and a quick learner. The primary aspect of his intelligence is his impressive skills in technology and mechanics; for example, he was able to build his own solar surfer all by himself when he was only 8 years old, and when he was able to fix up the late Captain Flint's spaceship in just a few minutes when he was 15 years old.
- Big Ol' Eyebrows: His mother even lampshades it.
- Blue Eyes: Which can be Innocent Blue Eyes or Icy Blue Eyes depending on the mood or how he's feeling.
- A Boy and His X: A Boy and His Morph. Morph took a personal liking to Jim and the feeling is mutual. Silver even tells Morph to stay with Jim; to be a reminder of the bond between Silver and Jim.
- Sarah once commented that Jim would bring home a stray pet and beg her to keep it.
- Brainy Brunette: See the Brilliant but Lazy section.
- Break the Cutie: Jim gets hit with this hard. He goes from being a genuinely upbeat, cute kid to a brooding teenager because of the way his father abandoned him. There's also the fact that he regularly has trouble with the law, isn't doing very well in school, wants to make his mom proud...
- Brilliant but Lazy: He's pretty good at building things and figuring out mechanical stuff, but at the start of the film he only uses that to amuse himself.
- Byronic Hero: Melancholic, sullen, attractive (the fans seem to think so), sensitive, surprisingly cunning, and cynical. He may be young, but he's a good qualifier for it. Over time some of his more negative personality traits simmer down.
- Celibate Hero: He doesn't have any romantic interest during the entire movie.
- Character Development: Jim goes from the moody, sullen, rule-breaking Emo Teen, who only uses his smarts for his own amusement to a military cadet who is more happy and smiling, and learns not to be so angsty.
- Child Prodigy: A former one. He built his own solar surfer when he was eight.
- Cool People Rebel Against Authority: Deconstructed. Jim is cool, and a rebel, but he is emphatically not cool because of being a rebel. Indeed, his bad attitude is the source of most of his problems, including his strained relationship with his mother. His Character Development largely revolves around him learning to direct his energy to do good instead of just blind disobedience.
- Crouching Moron, Hidden Badass: Jim is a lot smarter and pragmatic than most give him credit for. Over the course of the movie, he learns to curb his impulsive tendencies and think more logically.
- Deadpan Snarker: Not too extreme, but he has a few snarky comments.
- Death Glare: He gives a really frightening one to B.E.N. Not that anyone could blame him.
- He's really good at these, thanks to the way his face and eyes are structured. The ones he gives to Scroop and John Silver are pretty sufficiently scary.
- Disappeared Dad: Which has a lot to do with the above tropes.
- Embarrassing Middle Name: Pleiades is a star cluster in the constellation Taurus. It is sometimes referred to as "seven sisters", which is odd considering he's a boy and an only child.
- Emo Teen: Jim is pretty down in the beginning.
- Expy: In a visual sense, his looks came from the deceased American actor James Dean.
- Fashionable Asymmetry: Jim's gold earring.
- Fat and Skinny: The Skinny to Silver's Fat.
- Friend to All Children: Shows shades of this in a deleted scene when he briefly befriends a young boy named, Ethan.
- Friend to All Living Things: Implied by his mother's comment on how Jim would always bring home stray pets and beg her to let him keep them.
- Gadgeteer Genius: He's handy with machines.
- Goth: Has shades of this in the beginning.
- Good-Looking Privates: Well, more like cadet.
- He Cleans Up Nicely: Not bad looking by anything means, but he really shines wearing his Space Cadet uniform at the end
- Hello, Sailor!: He's a futuristic sailor in the film and has quite a female fan base out-of-universe.
- Heroic BSOD: Two examples.
- The first is after the supernova incident, when Jim is convinced that he was the one who murdered Mr. Arrow, he barks at Silver about how badly he screwed up. It's one of the more beautiful scenes in the movie, and marks a character shift for Jim.
- The second is when he learns Silver was actually a treacherous pirate all along - he tries his damnedest not to cry and then as Silver leaves the room to check out the threshold of Treasure Planet, Jim quietly stumbles around the room with a heartbroken, shocked expression on his face.
- Hidden Depths: Sure, he's a typical Emo Teen, but is much smarter and kindhearted than others believe.
- Important Haircut: He shaves off the ponytail he wore at the beginning, representing his emotional maturity.
- In-Series Nickname: "Jimbo" by Silver and "Jimmy" by B.E.N.
- His full name is James Pleiades Hawkins, but he's called "Jim" by almost everyone.
- Kid Hero: A deleted reveals Jim is 15.
- Like a Son to Me: Becomes one to Silver.
- Living MacGuffin: Only Jim can read the star-map.
- Morality Pet: To Silver.
- Mr. Fanservice: A rare example that doesn't have him shirtless.
- Nice Guy: He's got some issues, but he's still a genuinely nice kid.
- Sailor's Ponytail: He sports a classic hair style worn by sailors and swashbucklers.
- Sensitive Guy and Manly Man: The sullen, rebellious Manly Man to B.E.N. and Doppler's polite dorky Sensitive Guy. Although, he's only really a "manly man" in comparison to those two. In general, he's actually quite vulnerable, probably even more so than them.
- Also, the sweet, peaceful Sensitive Guy to Silver's short-tempered, strict Manly Man.
- Space Cadet: Becomes one after returning home.
- The Stoic: Hardly shows any emotion, except the usual teenage angst. He starts to change over time.
- Strong Family Resemblance: To his mother Sarah.
- Techno Wizard: He shows incredible prowess with machines, as demonstrated by converting a broken cannon into an engine in the climax.
- Teen Genius: Refer to above tropes.
- Teens Are Short: For a 15-year old, he's pretty short.
- He seems to have had a growth spurt at the end.
- ¡Three Amigos!: Jim, Morph, and Ben all fit this trope when they are all on screen together.
- Token Human: The only human on an expedition made up of aliens.
- Took a Level in Badass: From the mopey kid in the beginning to the skilled adventurer he is by the end.
- Took a Level in Cheerfulness: Jim went from a sullen, angsty teen to someone more optimistic and happier.
- Troubled, but Cute: No doubt he has issues, but he is pretty cute.
- Used to Be a Sweet Kid: Was a pretty energetic, cute kid to a broody teenager. He gets better though.
- "Well Done, Son!" Guy: Implied. In one of his flashbacks, Jim recalls the time he tried to impress his father with something he made. His father hardly paid any attention.
- Jim also wanted to go to Treasure Planet not only to help with the Inn, but to make his mother proud. And he does so.
- When He Smiles: Seriously, when Jim smiles it's a Crowning Moment of Heartwarming.
- Younger Than He Looks: Jim, at first take, looks a bit older than seventeen despite the shortness.
Voiced by: Laurie Metcalf
- Absurdly Youthful Mother: She can't be older than 35, and yet she has a teenage son.
- Break the Cutie: A rare adult version, but let's look at what she had to go through: Her troubles with raising Jim, the Inn burning down to the ground, and a flashback shows her weeping when Jim's father leaving his family. Seeing this woman so broken is heartwrenching. She got better though.
- Broken Bird: A flashback of Jim's showed his mother just breaking down in tears after his father left them. Combine that scene with what happened in the beginning and you'll know she qualifies.
- Death Glare: Where Jim gets it from.
- Friend to All Children: She has a fondness towards children.
- Glamorous Single Mother: Averted. She is not a single mother by choice (her husband just left straight up left her, for God's sake) and she struggles with her restaurant to get by. Possibly played straight at the end, though.
- He Is Not My Son's Father: She is horrified that the robot guards assume Delbert Doppler is Jim's father, accidentally insulting Delbert quite a bit.Sarah: Ew.

- Parents in Distress: When her restaurant is burnt to the ground.
- Platonic Life Partners: With Delbert.
- So Proud of You: When Jim comes home after finding Treasure Planet and becoming a military cadet.

- Tomboy and Girly Girl: The polite Girly Girl who runs an inn to Amelia's adventure-loving Tomboy who is later promoted to Admiral of the RLS Legacy.

Voiced by: Patrick McGoohan
- Alliterative Name: Billy Bones.
- I'm Dying, Please Take My MacGuffin: Unlike the book, Billy doesn't actually have any reason to give the navigation sphere to Jim particularly. He just doesn't want Silver to have it.

- The Call Knows Where You Live: He crash-lands outside the Benbow Inn.

- Authority Equals Asskicking: See Captain Amelia's Badass section and you'll know why.

- Blue Is Heroic: Captain Amelia wears a blue longcoat and is the established Big Good.
- British Stuffiness: She has a heavy British accent and was quite dismissive of Delbert and Jim at the start.
- The Captain: Of the RLS Legacy, obviously.
- Cats Are Mean: Averted. She's a Tsundere, but is one of the good guys.

Voiced by: Roscoe Lee Browne
- Adaptational Badass: The original Mr. Arrow was The Alcoholic and pretty useless. This guy's literally made of stone.
- Badass Longcoat: A badass and wears a longcoat
- Bald of Awesome: He doesn't even have a speck of hair because he is made of stone.

- Undying Loyalty: To Amelia.
Voiced by: Brian Murray
- Adaptational Heroism: Long John Silver of Treasure Island was very charismatic and managed to make all the heroic characters like him even as they distrusted the rest of the crew, but ultimately he was a murderous pirate who only cared for himself and the treasure. Here, he forms a genuine bond with Jim, as opposed to the empty flattery and lies he feeds him in the book, and ultimately sacrifices what's left of the treasure to save Jim's life.
- Adaptation Name Change: He's never referred to as anything other than "Silver", and is never confirmed to have the "Long-John" moniker he had in the original novel. Some dubs of the film, however, do use those references.
- Affably Evil: Never loses his affable nature, even after revealing himself as the villain.
- Anti-Villain: No doubt he's a villain, but no doubt he cares a lot about Jim.
- Artificial Limbs: A robotic arm, a robotic leg, and a robotic eye.
- Arm Cannon: Parts of his arm and leg, actually.
- BFG: Parts of Silver's mechanical leg and arm can combine to make what is either a very large gun, or a small cannon, in the span of a few seconds.
- Big Bad: He apparently burnt down Sarah's Inn and is leading a mutiny that complicates the journey to Treasure Planet. However, he eventually makes a Heel-Face Turn.
- Big Bad Friend: Although in this case, rather than chastising the hero for getting involved he ends up chastising himself for getting too close to a potential enemy.
- Big Fun: Until we learn the truth.
- A Boy and His X: A Man and His Morph. Silver found Morph in one of his adventures and they've been close ever since. Until Silver asks Morph to stay with Jim; a reminder of the close bond between Jim and Silver.
- The Casanova: Heavily implied with Amelia's line over Silver sweet talking some of "his spaceport floozies".
- Cat Folk: His appearance is vaguely cat-like, but not to Captain Amelia's extent.
- Cool Old Guy: He's very jovial and friendly, especially towards Jim.
- Cyborg: Mechanical right arm, leg, eye and possibly an ear.
- The Dreaded: It's clear that among the mutineers, his reputation is very, very dark. Even Scroop doesn't dare to fight him.
- Empowered Badass Normal: His physical prowess is impressive, even ignoring the obvious enhancements.
- Even Evil Has Standards: Before his eventual Heel-Face Turn if you look carefully, you'll notice the look he gave Mr. Scroop shows that he did not approve of his murder of Mr. Arrow at all.
- Fat and Skinny: The Fat to Jim's Skinny.
- Foregone Conclusion: It's an adaptation of Treasure Island, and this is Long John Silver. It's not too hard to figure out that he's secretly the head of the mutiny.
- Friend or Idol Decision: Jim or treasure? Jim.
- Handicapped Badass: Watching him cook with his mechanical arm is fun. And it turns into a cannon!
- Jerk with a Heart of Gold: He genuinely likes Jim.
- This ends up saving him, as that heart of gold convinces Jim to let him ride off into the sunset.
- Large and In Charge: He's the captain of the pirates.
- Last Name Basis: Though supplementary materials do refer to him as "John Silver", he's only ever referred to by his last name in the actual movie. It's easy to get the impression that he has Only One Name.
- Lovable Rogue: Is a pirate but has a genuine heart of gold.
- Love Redeems: His paternal love for Jim causes him to give up the treasure he's been searching for possibly his entire life just so the boy will live.
- Minored in Asskicking: Though he is the ship's chef, his leg is a damned howitzer and his arm can blow apart doors with a single shot.
- Mysterious Past: Jim asks how Silver got the mechanical cyborg limbs of his body, to which Silver replies: "You give up a few things, chasing a dream." The event is never mentioned again, but it's enough to make one wonder... what exactly happened to Silver?
- Noble Demon: His morals are loose, but there's no doubt that his concern for Jim is genuine. It's especially proven in the climax.
- Obfuscating Stupidity: While at first glance he's an affable, outgoing chef, in reality he is a cold and ruthless pirate captain.
- Though by the ending he seems to have softened a little bit.
- Parental Substitute: He is a mentor and father-figure to Jim. Considering how the story goes, is one of the more turbulent examples, but it all worked out in the most satisfying way possible.
- Red Oni, Blue Oni: The Red to Jim's Blue, and Blue to Scroop's Red.
- Red Right Hand: The mechanical part of his body which Bones warns Jim about.
- Riding into the Sunset: "Jimbo, laddie! When have I ever done otherwise?
- So Proud of You: His reaction to Jim saving the crew in the climax.
- Sensitive Guy and Manly Man: The short-tempered, strict Manly Man to Jim's sweet, peaceful Sensitive Guy.
- Swiss Army Appendage : His handicapped arm can go from a laser gun to a knife.
- Team Chef: The various bits of extra animal parts notwithstanding, Silver is a decent cook.
- Took A Level In Idealism: Up to Eleven [[when Silver abandoned a skiff full of gold and jewels to rescue young Jim Hawkins. Silver himself said it best: "'Twas just a lifetime obsession, lad. I'll get over it."]]
Voiced by: Dane A. Davis
- All Animals Are Dogs: Behaves like a dog mixed with a parrot and a budgerigar.
- Blob Monster: A tricky shapeshifter version.
- A Dog Named Dog: He morphs just like is name states.
- Expy: of Silver's parrot Captain Flint and most likely of Ditto
- Friend to All Children: Implied during his scene with Delbert and Amelia's children.
- Morality Pet: An almost literal one towards Silver.
- Pirate Parrot: One for the steampunk generation.
- The Prankster: Even at the worst moments possible like stealing the map and disguising himself as it during Silver's mutiny.
- Ridiculously Cute Critter: He's quite the cutie.
- Small Annoying Creature: But not too annoying.
- Team Pet: Because there has to be one.
- Undying Loyalty: To Silver and later Jim when Silver gives Morph to him.
- Voluntary Shapeshifter: Can transform into a mini version of anyone or anything.

- Ax-Crazy: Scroop's described as a "spider psycho." The fact that he attempts to kill almost everyone he comes across (and succeeds with Mr. Arrow) shows that.
- Big Bad Wannabe: Although he is also part of Silver's mutiny, he's more evil and seems to be a completely different kind of threat. But he never makes it to the treasure as he stays behind on the ship when they reach Treasure Planet and ultimately dies well before the climax.
- Big Creepy-Crawlies: He's effectively a giant walking spider/crab.
- The Bully: He's like this towards Jim.
- Decomposite Character: While he is rather clearly based off of "Israel Hands", a similarly unhinged pirate from the original novel there actually is a different crew member on the ship named "Hands" (though his name is never spoken in the film).
- Establishing Character Moment: Scroop introduces himself by attempting to kill Jim after the latter called him "bright-eyes."
- Evil Is Petty: Tries to kill Jim for insulting him and later succeeds at murdering Mr. Arrow for telling him off on this.
- Evil Sounds Deep: Really deep.
- Foil: To Jim as both have a serious disregard for authority. The difference being that Jim has a conscience and wants to be a better person. Scroop, on the other hand, is a murderous rogue, who kills Mr. Arrow, simply for telling him off and clearly isn't too keen on taking orders from Silver either.
- Hero Killer: Just one look at him and the audience knows he'll turn out to be a dangerous enemy. Proves this by murdering Mr. Arrow.
- Karmic Death: Just like Mr. Arrow, he gets sucked into space!
- Unlike Mr. Arrow, who probably died almost instantly in the black hole, the only way for Scroop to die was to dehydrate very slowly or collide with some deadly space phenomena.
- Kick the Dog: Harasses Silver about his care for Jim. Silver denies it.
- Knight of Cerebus: He's not onscreen for very long, but the fact that he murdered Mr. Arrow in cold blood and isn't Played for Laughs at all cements him as a presence worse than Silver.
- Mix-and-Match Critter: He's an alien that looks like a cross between a spider, scorpion, and a crab.
- Obviously Evil: Comparing him to Silver, who looks like a rather big lovable cyborg, Scroop is Red and Black and Evil All Over and has the appearance of a massive walking spider.
- Red and Black and Evil All Over: Scroop is an alien bug hybrid whose skin color is a combination of red and black. To prove his evilness, see his Hero Killer, Kick the Dog, and Psycho for Hire sections.
- Psycho for Hire: He's so sadistic he disgusts the otherwise near-amoral Silver.
- The Sociopath: Jim barely does anything and Scroop decides to get in his face.
- Sssssnake Talk: His voice is a raspy hiss.
- The Starscream: He would be this to Silver, except he never gets through with it before he dies. He never succeeds in doing anything Silver wouldn't want him to do other than kill Mr. Arrow, and it's not like that did anything to his plans.
Voiced by: Martin Short
- Advertised Extra: Way overhyped for this movie, probably to its detriment.
- Cloudcuckoolander: Mostly because a lot of his memory is missing.
- Funny Robot: The main comic relief and is the token robot.
- Happily Adopted: At the end of the film, B.E.N. goes to live and work at Sarah's restaurant. This is exactly like in the book, where Ben moved in and reformed entirely.
- I Just Want to Have Friends: His first scene shows him desperately trying to go on Jim's journey mostly out of loneliness.
- In-Series Nickname: B.E.N. stands for Bio-Electronic-Navigator
- Keet: An excitable, nervous Funny Robot.
- Mad Oracle: He seems to have lost his mind. Which makes sense because Flint has it.
- Motor Mouth: He annoys Jim since he never shuts up.
- Nervous Wreck: Justified as he is missing a part of his memory.
- Nice Guy: B.E.N. was probably the most nicest, selfless, helpful mates of Captain Flint's crew.
- Non-Standard Character Design: He's the only character in the film who is entirely animated with CGI, not that you'd notice.
- No Sense of Personal Space: To Jim. Understandable as he hasn't had outside contact in over a century.
- No Social Skills: Has trouble with being quiet, maintaining personal space and discerning friend from foe. He also forgets that carbon-based lifeforms don't drink motor oil.
- Odd Name Out: B.E.N. is the only character in the film whose name is actually an acronym.
- Plucky Comic Relief: The main comic relief and came quite handy in the climax.
- Sensitive Guy and Manly Man: The polite, dorky Sensitive Guy to Jim's sullen, rebellious Manly Man, although Jim isn't much more macho than he is.
- Smart Ball: When he finally gets his memory circuits back and remembers that Flint rigged Treasure Planet to explode should anyone try to steal from it. He becomes much more tolerable afterwards.
Captain Nathaniel Flint
Captain Nathaniel Flint
Voiced by: Corey Burton
- The Dreaded: He was the most feared pirate of his age.
- Extra Eyes: He has six eyes.
- Greater Scope Villain: Of a sort. He was a fearsome pirate, and it's his treasure (and the lengths he went to in order to keep it) that drives the plot. After Silver reforms, Flint is the closest thing the movie has to a main antagonist due to the reveal that he set the planet to explode when the treasure is found.
- Greed: Flint is so greedy that he never spent his pirate loot, aside from the cost of rigging his lair to destroy whoever tried to take said loot.
- No MacGuffin, No Winner: Apparently, he had this attitude toward his treasure. Rather than allow anyone else to get their hands on it (even with Flint himself long dead), he rigged the entire planet to explode if anyone entered the treasure chamber.
- Posthumous Character: By the time of the story, he's long-dead. Finding his skeleton in the treasure chamber proves this beyond any doubt.
- Reptiles Are Abhorrent: Whatever race he is, it seems fairly saurian.
