!!Milo James Thatch

[[caption-width-right:350:''"But hey, you know, that's what this is all about, right? I mean, discovery, teamwork, adventure!"'']]

-->''"--Now what’s really amazing is that if you deconstruct Latin, overlaid it with a little Sumerian, throw in a dash of Thessalonian, you’d be getting close to their grammatical structure. Or at least in the same ballpark. Which is almost exactly like certain obscure offshoots of Chocktaw! Well, obviously using Greek pronunciation, but you get the point, proving once and for all, that Atlantean trade routes accessed the new world centuries before the Bronze Age! Take that, Mr. Harcourt!"''
--->'''Voiced by:''' MichaelJFox

* {{Adorkable}}: One of the reasons the fangirls adore him. He's also the poster boy for this trope.
* BadassBookworm: Milo [[TookALevelInBadass becomes this]] during the last action sequence.
* BowTiesAreCool: Wears one at the beginning of the film.
* BrainyBrunette: Milo has brown hair and let's look at the info below:
** Educated at Oxford University (1896-1903), Thatch holds a double doctorate in the fields of Linguistic Theory (Grammatical Structure, Syntax, Babel Theory, Evolution, Written Languages, and Lost Alphabets) and Dead Languages (Cryptology and Hieroglyphics, with thesis work done on American Indian tribes of the California Coast, Hawaiian, Pacific Island, and South Asian/Sub-Continent Strains).
** He had minor degrees in Chemistry, Literature (French, Old English, and Chinese), Art History, Sociology, and Anthropology. In addition to his formal training as a linguist and translator, Milo was tutored by the legendary Thaddeus Thatch, his grandfather, in the fields of Cartography, Drafting, Navigation, Astronomy, Archeology, and Antique Restoration Techniques.
** Employed in Washington, D.C. as a Museum Linguist/Translator and Cartographic Restoration Expert, 1903-1904. Participated in Academic Exchange Program 1909-10, spent 11 months working in Paris at the Bibliotech National, and the Prado Museum in Madrid.
** Also, see the HiddenDepths section.
* ButtMonkey: At least until he [[TookALevelInBadass takes responsibility]], [[BadassBookworm saves Atlantis]], and get's the girl.
* CunningLinguist: An "expert at gibberish".
* DistractedByTheSexy: Every time he's around Kida. Just look at his reaction when he first lays eyes on her. He forgets his own pain!
* GoingNative: At the end of the film.
* HeroicBSOD: After Kashekim dies and all seems lost.
-->'''Sweet:''' I followed you in and I'll follow you out. It's your decision.
-->'''Milo:''' Oh, my decision? Well, I think we've seen how effective ''my'' decisions have been. Let's recap. I lead a band of plundering vandals to the greatest archeological find in recorded history, thus enabling the kidnap and/or ''murder'' of the royal family. Not to mention personally delivering the most powerful force known to man into the hands of a mercenary ''nutcase'' who's probably going to sell it to the Kaiser! Have I left anything out!?
* HiddenDepths: He's an eager but put-upon linguist and cartographer... who also knows an awful lot about plumbing and boilers, right down to how to treat certain brands and models.
* KindheartedCatLover: Milo has a white Persian named "Fluffy."
* [[ABoyAndHisX A Man And His Cat]]: Prior to the film's adventure, he lived alone in an apartment with his pet cat.
** [[ABoyAndHisX A Man And His Lava Dog]]: In the sequel Milo and Kida own a lava dog named Oggie.
* MasculineGirlFeminineBoy: Next to the Atlantean Princess. Most definitely.
* MayflyDecemberRomance: With [[Really700YearsOld Kida]].
* {{Megane}} / NerdGlasses
* MightyWhitey: He has none of the characteristics that are usually ''associated'' with the trope, but he fulfills it anyway. An unusual variation in that he actually ''saves'' the native peoples' culture, while most examples of this end up doing the opposite.
* NaiveNewcomer: He was only brought on the team because they needed a linguist.
* TheNavigator: Due to being the only one who can translate the Shepherd's Journal, though he does occasionally get it wrong.
* NiceGuy: That and [[{{Adorkable}} his dorky, quirky nature]] are the main reason why he has such a huge, out-of-universe female fanbase.
* OfficialCouple: With Kida. It's downplayed, though.
* RaisedByGrandparents: After his parents died, his grandfather raised him.
* ScienceHero: He is probably the smartest guy on the team.
* ScrewTheMoneyIHaveRules: More like Screw The Money, I Have Morals.
* TookALevelInBadass: By the end of the film.
* TragicKeepsake: Milo kept his grandfather's explorers hat.

-->''"Solesh mat-o-not, Maylo Thatsh-top. Kwam tered-se-nen." {All will be well, Milo Thatch. Be not afraid.}''
--->'''Voiced by:''' Creator/CreeSummer

* AmbiguouslyBrown: And since Atlantis is cut off from natural sunlight it's probably not a tan.
* BadassPrincess: In a brief yet oh-so-satisfying action scene in which she flips one of Rourke's gas-mask mooks over her head and into the drink when he pulls her out by the hair, [[GroinAttack knees a guy in the crotch]], physically ''lifting'' him off his feet! Bashes another in the skull with the butt of his buddy's rifle while trying to wrench it free from its owner, and knocks another soldier to the ground while drawing her knife to dispatch him. Even better when she showcases skills as a hunter/gatherer and is implied to have dealt lethally with any explorers encroaching on Atlantean boarders for thousands of years.
* BadassDecay: In-universe.
-->'''King Kashekim:''' Your heart has softened, Kida. A thousand years ago, you would have slain them on sight.
* BareYourMidriff: Until the end of the film, when she is made queen and wears a robe.
* TheChiefsDaughter
* CoolCrown: Her tiara at the end of the film.
* CombatPragmatist
* DarkSkinnedBlonde: Apparently, it's standard for Atlanteans.
* DeadlyUpgrade: The crystal, which preserves the life of Atlantis, will merge with a royal host if it senses danger. Since Rourke is threatening it, it merges with Kida, putting her into a vegetative state that will kill her if she is in it too long, as it did to her mother when Atlantis first sank.
* DoesNotLikeShoes
* EmpoweredBadAssNormal: When joined with the Heart, Kida has the power to both levitate and telekinetically activate the engravings of the Kings and project bolts of energy into the Stone Sentinels that guard the perimeter of the city. She channels an ungodly amount of power that is enough to both halt and ''freeze'' an erupting pyroclastic flow and lava torrent from a powerful volcano within seconds and then break apart the resulting mantle. It's also quite safe to say that you ''don't'' want to lay a hand on her while she's in this form.
* FauxActionGirl: ExecutiveMeddling made her into this, unfortunately. Fortuitously, [[{{Xenafication}} she gets better]] in the sequel.
* GiveGeeksAChance: Her dynamic with Milo, obviously.
* GroinAttack: ''Twice'' on the same poor schlub, within the span of ten seconds.
* HealingHands: Another power of the personal crystal necklaces, though Kida shows that its power may be virtually untapped if it can heal all physical ills save eventual old age and death. This ties back to the "advanced medicine" Milo claims the Atlanteans once (and still do) possess.
* TheHighQueen: After she follows in her father's footsteps at the end of the film, with Milo as her HotConsort.
* IllKillYou: To Rourke, after he mortally wounds her father. She succeeds in carrying this out by proxy, providing Milo with the means.
-->''"Moh-it gwenog-lo-nik!" {I will kill you for that!}''
* InSeriesNickname: She goes by the sobriquet of "Kida".
* LeParkour
* MacGuffinGirl: Once she merges with the Atlantean crystal.
* MasculineGirlFeminineBoy: She would have been more than a match for Rourke. the younger Thatch is sopping-wet next to her.
* MayflyDecemberRomance: With Milo, who has only lived a very small part of her lifetime.
* MegatonPunch: To Mole after he whispers a rather promiscuous proposition to her in French. Mole weighs over ''300lbs''.
* MissingMom: Kida's mother was exposed to the crystal's power for too long and died as a result. She is briefly seen in the [[ColdOpen intro]].
* MsFanservice: Despite her age.
* MysticalWhiteHair: White hair seems to be a racial trait of all Atlanteans, suggestive of their longevity (but not their age—the children have white hair, too).
* NubileSavage: Even though she's thousands of years old.
* OfficialCouple: A downplayed version with Milo. There is some mutual attraction during the movie, but it's not really a love story.
* {{Omniglot}}: Because according to Milo, ''all'' modern languages in the Northern and Southern Hemispheres descend from Atlantean, so she can speak English perfectly, as well as Greek, Latin, French, Mandarin, Hebrew, Norse and of course; Atlantean.
* PowerGlows: When she merges, she's drawn entirely with white lines and luminous blue-white surfaces for a very eerie "supercharged" effect.
* SecondLove: Bonus material points out that she is this to Milo, surprisingly.
* ShesGotLegs
* SuperNotDrowningSkills: She can't ''breathe'' underwater, but is still an amazing diver. Justified considering she's been practicing in a half-sunken city for a ''long'' time.
* ReallySevenHundredYearsOld: She's anywhere from 8,500 to 8,800 years old when we accept that she was ''a child'' at the time of the great flood.
-->'''Milo''': Oh, well. Hey. Looking good!
* RoyalsWhoActuallyDoSomething
* TheUnpronounceable: Milo can't seem to get his tongue around her full name.
* TomboyPrincess
* TragicKeepsake: In a very brief moment near the beginning of the film, Kida's bracelet is pulled off by her mother as she's called into the Heart of Atlantis. When Kida herself returns from the crystal's possession near the end, she has the bracelet with her.
* VoiceOfTheLegion: When under the possession of the Mother Crystal.
* WalkOnWater: As the Heart of Atlantis beckons to her.

[[folder:Commander. Rourke]]

!!Commander. Lyle Tiberius Rourke

[[caption-width-right:350:''[[BlatantLies "But we are peaceful explorers, men of science."]]]]''

-->''"I love it when I win."''
--->'''Voiced by:''' [[Film/TheGreatEscape James]] [[Series/{{Maverick}} Garner]]

* AxCrazy: Downplayed until the climax, where he goes into a VillainousBreakdown.
* AnAxeToGrind: He grabs a nearby fire axe during his fight with Milo.
* BigBad: He is the leader of a group of mercenaries that are after the crystal.
* BloodKnight: Do you see his picture there?
-->"Getting ''tired'' Mr. Thatch? Aw, that's a darn shame. Cause' I'm just getting warmed up!"
* BodyHorror: What happens to him after his arm is sliced with a piece of glass charged with crystal energy.
* ClippedWingAngel: Unlike most Disney villains, turning into a monster does ''not'' make him more powerful--as he claws his way after Milo, it's implied that moving causes him pain.
* ColonelBadass: It's unfortunate he's the BigBad.
* CrazyPrepared: According to Audrey, Rourke is "never surprised" and "carries a lot of guns." Both of which are slight {{understatement}}s.
* EvilAllAlong: Starts off seeming like a tough-but-fair leader, but it turns out that he was after the crystal from the very beginning.
* EvilHasABadSenseOfHumor: When he reveals his true colors, he makes more wisecracks than one might expect from a naval officer. Instead of making him AffablyEvil however, it makes him more despicable, for instance when Dr Sweet protests after Rourke [[MoralEventHorizon fatally punches the King]], the villain quips back:
--> "I suggest you put a bandage on that bleeding heart of yours, it doesn't suit a mercenary."
* FamilyUnfriendlyDeath: After being, [[BodyHorror painfully,]] transmogrified into a crystal monstrosity when Milo slashed his forearm with a piece of irradiated glass from the Kida's containment tank window, he is literally shattered into tiny bitty pieces by the whirling helicopter blades.
* FauxAffablyEvil: Even when he throws [[TheDragon Helga]] off the platform, he calls out cheerfully, ''"Nothing personal!"'' after her!
** Notably, as they get closer to Atlantis, his demeanour becomes less "military commander" and more like a jovial uncle, always cracking jokes even when he's threatening Milo or the King.
* GasMaskMooks: His henchmen.
* HoistByHisOwnPetard: Tossing Helga off the gyro-balloon to lighten the load was what really messes up his plans.
* LightningBruiser: He outweighs Milo by a hundred pounds, easily. And he's faster. It's a CurbStompBattle.
* LiterallyShatteredLives: His eventual fate.
* InsistentTerminology: "Mercenary? I prefer the term ''adventure capitalist''."
* OnlyInItForTheMoney: To the point where he just tries to steal the crystal to get even more money.
* PainfulTransformation: Rourke is clearly screaming in pain when the crystal energy overwhelms him.
* PlotBasedPhotographObfuscation: Early on, Milo notices that there's a page missing from the Sherpherd's Journal. Later on, it turns out that the missing page describes the properties of the legendary crystal in detail. Rourke's the one who ripped it out.
** When Whitmore is showing Milo the crew files, Rourke's is the only one obscured.
* PunchCatch: On poor, brave Milo.
* SlasherSmile: Sports one in the climax when the VillainousBreakdown comes into play.
* VillainousBreakdown: As Milo proceeds to ruin his attempt to air-lift Kida to the surface, Rourke starts trying to cut him to ribbons with a fire axe.
-->"I consider myself an even-tempered man; it takes a heck of a lot to get under my skin. But congratulations--you just won the solid gold Kewpie doll!"
* ZeppelinsFromAnotherWorld: A justified use, since the movie takes place at the pinnacle of the zeppelin period. The general design is actually taken from high-altitude meteorological balloons of the period.

[[folder:Helga Sinclair]]

!!Lieutenant. Helga Katrina Sinclair

[[caption-width-right:350:''"You promised me a percentage!"'']]

-->''"Well, I came down the chimney. Ho, ho, ho."''
--->'''Voiced by:''' [[Series/BabylonFive Claudia Christian]]

* BadassLongcoat: Briefly wears one.
* BlondesAreEvil: She is the only named character who doesn't oppose Rourke.
* BeautyMark
* DarkActionGirl: Eviler than the other named female characters.
* DisneyVillainDeath: Subverted. It wasn't the fall that killed her (although it quite possibly broke her back and/or caused quite a bit of internal bleeding), but having a flaming gantry crash down on top of you would certainly do the trick.
* DeadpanSnarker: She has her moments.
* TheDogBitesBack: It's Helga's [[LastBreathBullet igniting the hydrogen]] after Rourke betrays her that really foils the EvilPlan.
* TheDragon: To Rourke.
* FemmeFatale: Don't let her hotness fool you, she is a mercenary.
* FlareGun: Has one tucked away. She uses it on Rourke's escape balloon in the climax.
* HeelFaceDoorSlam: Helga shows some remorse when she discovers that they will be stealing from living people and not a long-dead civilization, but she is betrayed and mortally wounded by Rourke before she (possibly) switches sides.
* LastBreathBullet: Well flare actually, but it still fits.
* NothingPersonal: "Nothing - ''Personal''." Her FamousLastWords, doubling as an IronicEcho.
* RightHandCat: The standard white Persian, although it's actually Milo's.
* PerpetualFrowner: She's almost always scowling.
* {{Sexophone}}: Heard when she makes her debut in Milo's apartment.
* TankTopTomboy: Wears one near the finale, despite the fact that they hadn't even been created during the time the story takes place.
* TakingYouWithMe: Obviously badly injured, she fires a flare into the balloon that her murderer is using to escape.
* ThrownFromTheZeppelin: She is literally thrown off one in the climax.
* WaifFu: Tries to use this gymnastic, kick-heavy style on Rourke. She gets thrown off ''again'' despite her efforts.

-->''"With something like that, I would have, white wine, I think."'' '''- Vinny, on the Leviathan'''
--->'''Voiced by:''' Don Novello

* {{Badass}}: Takes out the most bi-planes in the climactic dog-fight free-for-all, lures Helga's Mauser fire away from the others while they try to rescue Kida and even disarms Rourke of his Lewis-gun by blasting it in two and out of his hands with a ''mounted vehicle weapon''.
-->"Okay, ''now'' things are getting good!"
* DeadpanSnarker: Very much so.
* DemolitionsExpert
* EvenEvilHasStandards: A self-admitted example in that he doesn't care if he hurts people ''unknowingly'' but won't stand for it when it's rubbed in his face.
* HeelFaceTurn: Along with the rest of the group when Milo calls them out.
* HeroicComedicSociopath: Has some of the most violent lines in the movie. They're also some of the funniest.
* OnlyInItForTheMoney: Averted by the end. But he's rewarded handsomely anyway!
* TheStoic: Most of the time, he has a very bored expression on his face. He only really smiles twice in the movie: after blowing up the pillar to make a bridge, and when he discovers the explosive capabilities of the Atlantean Aktirak's {{Wave Motion Gun}}s.
* StuffBlowingUp: Vinny loves explosions, but not enough to be a BombThrowingAnarchist.
* {{Troll}}
-->'''Vinny:''' You didn't just drink that, did you?
-->'''Milo:''' ''(Nods happily)''
-->'''Vinny:''' That's ''not good'', that's nitroglycerin! Don't move, don't breathe, don't do ''anything.'' Except, uh...pray, maybe.

-->'''Whitmore:''' ''"Don't let her age fool you. She's forgotten more about engines than you and I will ever know."''
--->'''Voiced by:''' [[Film/SixDaysSevenNights Jacqueline Obradors]]

* {{Badass}}: In a blink-and-you'll-miss it moment during the Leviathan attack on the Ulysses, Audrey ''deflects'' ricocheting rivulets bursting from the pressure away from her face with a coal shovel!
* TheBully: Claims that she used to take lunch money from guys like Milo. Perhaps it's true?
* ChewBubblegum: Though she doesn't utter the immortal line. The very act of her blowing and bursting the bubble during Milo's presentation to the rest of the group seems to unnerve him even more than he already is.
* DaddysGirl: Strongly implied; she wants to earn enough money from the expedition to open another shop for her father's business.
* DeadpanSnarker: Occasionally.
* DefrostingIceQueen: She's rather abrasive to [[NaiveNewcomer Milo]] at first, but once she warms up, she's quite a softie.
* NiceGirl: The first to take notice of Milo's [[WhatTheHellHero admonishments]] and the first to fully support him after Rourke beats him down.
* NiceHat: One that manages, against all odds, to stay on her head for nearly the entire film, until she swaps it for a different hat to go with her formal dress while meeting with Whitmore at the end.
* SpicyLatina
* TeenGenius: The youngest member of the team, and an ace mechanic.
* {{Tomboy}}: She reveals in her backstory that her father wanted boys.
* WrenchWench: She's the one in charge of repairs and maintenance.
* WrongSideAllAlong: The audience gets to see foreshadowing of Rourke's greed and lack of respect. But the crew, Audrey in particular, seem horrified when Rourke starts kidnapping women, punching old men and being a-okay with condemning hundreds if not thousands of people to ''death'' for his own personal profit.

* ArcWords / BrutalHonesty
-->"We're all gonna die."
* BeenThereShapedHistory: She's the "Packard" in "Packard-Bell", according to WordOfGod.
* CuriousQualmsOfConscience: The last of the group's specialists to take Milo's side. For no other reason than perhaps... ''Meh''.
* DeadpanSnarker: Every other sentence that comes out of her mouth drips with snark. She's particularly sardonic when making announcements over the ''Ulysses'' tannoy.
* DissonantSerenity: ''(Gargantuan Leviathan Machine of War fires beam of energy through the Ulysses, crippling it and dousing the boilers with sea water.)''
-->'''Audrey:''' ''(Trying to hold it together)'' Get me the bridge!
-->'''Mrs. Packard:''' ''(Opens 'Crime' magazine)'' Sir, it's engineering on four.
* DitzyGenius: She seems to be barely fazed by all the craziness happening around her, but despite this supposed senility, she does her job with a calm that can provide stability in trying times.
* DudeMagnet: She manages to get some ''very young'' Atlantean men to fight over her. And has been previously married to ''eleven'' husbands.
* DullSurprise: She doesn't surprise easily. Heck, it takes colossal statue guardians coming to life to impress her!
* FanDisservice; Although we mercifully don't get to see if this is the truth. She apparently sleeps in the nude -- and she sleep-walks.
* FantasticallyIndifferent: Where ''a lot'' of the humour around her character stems from. No matter how intense the danger. She spends the finale ''taking photographs''.
* UnfazedEveryman: A prehistoric war machine has mortally crippled the sub and in five minutes the boiler is going to kill anybody left aboard!
--> '''Packard''' ''(into the radio):'' I gotta go Margie. No, no, I'll call you.
* WhoWritesThisCrap: When she's doing public announcements aboard the ''Ulysses.''

--->'''Voiced by:''' Phil Morris

* {{Badass}}: Doesn't get any notable moments on-screen, but his backstory is awesome enough. Being a combat medic in the Spanish-American War and the Boer Wars while being on friendly terms with a young Theodore Roosevelt automatically elevates you to one of these.
* ChekhovsGun: His saw, which he draws attention to at the beginning of the film and which he and Audrey later use to try and free the crystallized Kida. Maybe if ''he'd'' done the sawing instead, the plan might have worked.
* DareToBeBadass: Even this is delivered to Milo as a touching reminder instead of a harsh rebuke.
-->'''Sweet:''' Of course, it's been my experience, when you hit bottom, the only place left to go is up.
-->'''Milo:''' ''(Dismissive)'' Huh. Who told you that?
-->'''Sweet:''' A fella by the name of Thaddeus Thatch.
* GentleGiant: A refreshing aversion from the ScaryBlackMan trope.
* HypocriticalHumor: Claims to hate fish yet tucks into the Atlantean meal (consisting mostly of crustaceans) Kida serves to the group with particular zeal.
* LastNameBasis: He is often just called Sweet.
* MeaningfulName: He is one of the friendliest and most decent members of the group, and the first to HeelFaceTurn (after Rourke gut punches Kida's father).
* MotorMouth: Particularly brought to attention during his initial checkup on Milo, where he keeps talking despite Milo having a thermometer in his mouth.
* NiceGuy: Mentioned by Milo when he's attempting to teach Kida the names of his teammates. Milo has some trouble making a distinction for her between the names "Sweet" and "Cookie" and that cookies are sweet and that Sweet is a nice person.
* TeamDad: He is the wisest and most compassionate member of the group.
* TwoferTokenMinority: He's African-American and Native American.

* AmericansAreCowboys: Unsurprising, since he was a quartermaster, mule-skinner, rifle-man, scout and fur-trapper in the US Army during the Civil War and the subsequent Sioux Wars.
* BadassGrandpa: 72 by the events of the first film and still kicks ass, riding shotgun at the climax.
* CampCook: Unfortunately, he is also a LethalChef.
* ColdSniper: With a double-barreled musket, of all things. Though considering that he's on the side of the good guys in the climax, he's more of a FriendlySniper.
* DisproportionateRetribution: When working as a restauranteur in New York, a customer complained about his culinary skills. Cookie was subsequently fired for ''shooting him in the knee''.
* TheDitz
-->"I seen this in the Dakotas! They can smell fear just by looking at ya. So keep quiet."
* LethalChef: His cooking, when thrown on the campfire, [[EverythingMakesAMushroom makes a mushroom cloud]] at one point. Not surprising, considering the grease content. He's also ''horrified'' when presented with an ordinary head of lettuce.

--->'''Voiced by:''' CoreyBurton

* AnimalMotifs: Moles, obviously, due to his PunnyName, obsession with dirt, and even physical resemblance to one. He even carries a plush mole that he presumably sleeps with.
* BigEater: One of the few who tucks into Cookie's meals with ''gusto.''
* FatBastard: Downplayed, in that he's a mild FrenchJerk with questionable social skills.
* TheFriendNobodyLikes: Everybody in the group is disgusted by him, and it says quite a lot that in a group that includes Cookie, Vinnie and Mrs. Packard that ''he'' is considered the biggest freak around.
* GeniusDitz: He seems to be "out there" on everything other than geology, his specialty.
* GeniusSlob: The Mole, dirt is his job and his hobby. Brilliant geologist. Sleeps in a hole he digs out for himself.
* [[SheCleansUpNicely He Cleans Up Nicely]]: As the end of the film shows, he really doesn't look all that bad when he's properly cleaned and formally dressed. He's clearly uncomfortable with it, though, and buries himself in a large flowerpot at the first opportunity.
* MotorMouth: When analyzing a dirt sample, he talks very rapidly and very quietly to himself.
* NiceHat: His is a leather cap with a variety of minute clockwork tools, telescopic / microscopic binocular lenses and a mini torch lamp.
* ThePigPen: To the degree where ''soap'' is a CoolAndUnusualPunishment.
* OnlyKnownByTheirNickname
* PunnyName: What do you expect, considering that he's an expert on digging and seems the most comfortable when burying himself in dirt?
* SherlockScan: He ascertains all of Milo's profession and home life merely by examining the dirt under one of his fingernails.
-->"Aha! There you are. Now tell me your story my little friend... [[AwesomeByAnalysis Parchment fiber from the Nile delta circa 500 B.C. Lead pencil, number two.

-->"Some obstacles cannot be removed by a mere show of force."
* BadassBaritone
* BadassBeard
* BlindSeer: Metaphorical, after the great flood robs him of his vision by him staring into the Heart as his wife ascends and he shields Kida from the sight. His eyes are opened to the magnitude of his mistakes.
* CoolOldGuy: He is voiced by Spock after all.
* GrumpyOldMan: But is also a bit of this too. Though not without good reason.
* KilledOffForReal: Dies of internal bleeding brought on by a punch to the gut from Rourke.
* MyGreatestFailure
* MrExposition
* ProphetEyes
* SecretLegacy: Considers himself personally responsible for nearly destroying the Atlantean Empire. Because he weaponized the Heart Crystal to power massive engines of war and conquest and even developed a thermo-nuclear weapon / meson bomb of such might that it ''caused'' the tsunami that sank the city.
* TimeAbyss: At least 27,000 years old, considering that for every 300 years that passes, an Atlantean of royal lineage ages just ''one''. So physically, he's anywhere from being in his 90's but considering his age during the Mebel-mok, (30's-40's), he's probably closer to ''40,000 years old'' and one hundred and thirty-ish physically; accounting for his frailty.
* VictoryThroughIntimidation: By his sheer presence alone, he manages to get Rourke to back down from attempting to explore the city for the Heart Of Atlantis and agree to leave by morning. Unfortunately, it only worked while Rourke was still pretending to be nothing more than a peaceful explorer.
