[[folder:Main Characters]]
!!Mister Traveler/[[spoiler:Quote]]
%% Yes he's identified as that in the manual for the DSi port.
The PlayableCharacter. An amnesiac who awakes in a small cave in the depths of a strange island.
* AccidentalPervert: He can optionally find [[spoiler: Curly's panties in a hidden passage of the Colons' house]] in the Sand Zone. And no, they don't do anything.
** They have a purpose in the Plus edition, [[spoiler: They unlock Curly as a playable character]].
* AmnesiacDissonance: [[spoiler:It's eventually revealed that he was one of many robots sent from the surface to kill the Mimigas and claim the Demon Crown.]] [[spoiler: {{Subverted}} if you restore Curly's memories, when she remembers that the two of them were made separately to destroy the Demon Crown, so he's actually doing what he was made for after all.]]
* AmnesiacHero: [[spoiler:He was really a robot sent from the surface to destroy the Demon Crown. He also never recovers his memories; Curly Brace has to tell him all this after she recovers her own memory.]]
* {{Badass}}: Justified because he's a soldier [[spoiler: (specifically a scout droid)]].
* HeroicAlbino: [[spoiler:Since it's not actually skin, but probably some kind of polymer.]]
* HeroicMime: Even when you're playing as Curly, he only talks out loud ''once''.
* HyperspaceArsenal: He can carry vast amounts of weaponry, various keys he doesn't even need, various devices that are built ''onto'' his weapons, jars, food, and badges, and at the end of the day, still have enough room to fit panties and lipstick in too.
* LightningBruiser: Very nimble ([[spoiler:especially with the Booster upgrades]]), wields plenty of powerful weapons, and can potentially survive a lot of damage with sufficient Health upgrades.
%%* NiceHat
* OnlyOneName: [[spoiler:It's "Quote." It's said only once in the whole game when Curly recovers her memories (or, if you're playing in Curly Mode, the only line he says out loud).]]
* RedAndBlackAndEvilAllOver: With that red hat and black shirt, you start off with everyone thinking you are [[spoiler:a battle robot and "Mimiga-butcher"]]. The fact that you ''are'' a soldier doesn't help. [[spoiler: Subverted later on when you learn that you were sent to destroy the Demon Crown rather than the Mimigas.]]
* [[spoiler: {{Ridiculously Human Robot|s}}: As we learn from Professor Booster, despite his human-like limitations.]]
%%* ScarfOfAsskicking
* SeriesMascot: Alongside [[AscendedMeme Balrog.]]
* ThemeNaming: [[spoiler:Quote Marks " are widely used in programming software]].

!!Curly Brace
A mysterious young woman who seems to know a bit about our hero.
* ActionGirl: Justified. [[spoiler:Like Quote, she's a robot sent from the surface to destroy the Demon Crown.]]
* BadassAdorable: About as cute you can be for a [[spoiler:deadly robot]].
* BackToBackBadasses: In the Sacred Grounds, if you got the Iron Bond item, she'll ride on the main character's back, shooting things with her machine gun.
* ContractualBossImmunity: Aside from preventing drowning, her bubble tank also grants immunity to otherwise overpowered missiles.
* DefeatMeansFriendship: The first time the player meets her, she thinks he's there to kill the Mimigas. After defeating her, she actually listens to him, and puts her weapons down.
* GameplayAllyImmortality: During the segment in the Labyrinth where she fights alongside the protagonist, she is completely invincible. She can even walk through spikes.
* GenkiGirl: Upbeat is pretty much her default mood.
* GuestStarPartyMember: During the second half of the Labyrinth.
* HeroicSacrifice: After the battle with the Core, she gives you her bubble-tank and drowns in your place. She can be revived if you ignore the injured Booster and pick up a tow-rope in the chamber.
* LetsYouAndHimFight: Attacks the player character almost immediately after he meets her.
* LightningBruiser: She can become one, just like [[spoiler:Quote]], when playing as her in Curly mode.
* MoreDakka: Her Machine Gun, which she'll offer to you after beating her; she takes the Polar Star in return.
* {{Nice G|uy}}irl: She and Quote have a little [[PoorCommunicationKills misunderstanding]] when they first meet but even then it was only because she was trying to protect some Mimiga kids she was taking care of. [[spoiler: She also [[HeroicSacrifice sacrifices]] herself to keep you alive for no reason other than that she wanted to.]]
* [[spoiler: {{Ridiculously Human Robot|s}}: She can eat and ''digest'' food, among lots of other little things.]]
* SuperNotDrowningSkills: Thanks to an oxygen tank that she carries around, an oxygen bubble forms around her every time she steps foot in water. [[spoiler:She gives it to you after the Core fight.]]
* ThemeNaming: Curly Braces { } are widely used in programming software.

!!Sue Sakamoto
A fiery young girl being pursued by the Doctor's henchmen.
* BadassBoast: gives one before fighting Igor. She fearlessly tells him to "Bring it on!" and that she's stronger her brother. [[spoiler: However, that doesn't mean much as said brother isn't particularly strong, and unfortunately it doesn't end well for her...]]
* BalefulPolymorph: Got shapeshifted into a mimiga thanks to Misery.
* DemonicPossession: By the Doctor in the final battle. Temporary, fortunately.
* DistressedDamsel: On several occasions.
* FauxActionGirl: Just as she encounters a frenzied mimiga, she brags about how she defeated Kazuma in a fight ([[NonActionGuy which isn't saying much]]). Cue NoHoldsBarredBeatdown.
* {{Tsundere}}: First time you meet her, she gets rather annoyed if you say you wanted to save her (and annoyed if you say no), but she eventually softens.
* YouGottaHaveBlueHair: Her true hair is green.
* XMarksTheHero

The leader of the Mimiga village, and Toroko's brother-figure.
* {{Badass}}: He takes down [[RecurringBoss Balrog]] in a single hit.
* BigBrotherInstinct: He's ''very'' protective towards Toroko.
* BackupFromOtherworld: The fully upgraded Blade is less [[spoiler: Quote]] launching {{Sword Beam}}s, and more King's spirit swiping at anything he's targeting.
* CoolSword: [[spoiler:And he passes it onto your hands after taking a fatal blow from The Doctor.]]
* FaceOfAThug: He certainly ''looks'' rather sinister, but he's a case of GoodIsNotNice ''at worst''.
* GlassCannon: [[spoiler: He beats Balrog, who is a StoneWall, in a single blow. However, all it took was a single hit from The Doctor to defeat him]].
* GoodScarsEvilScars: Has a nasty scar on across his face, which adds more to his FaceOfAThug, but he's unarguably good.
* IllKillYou: Utters this to Doctor when he meets him.
* NotTooDeadToSaveTheDay: As mentioned above, the third level power for the sword is not as much throwing the sword as it is sicking King's soul at the enemy.
* RedEyesTakeWarning: Subverted in that he's a good guy regardless of this trope applying for him. [[spoiler: This is because [[WordOfGod Pixel]] confirmed that King indeed ate red flowers, but cooked them, which gave him strength but didn't turn him.]]
* SacrificialLion
* TestosteronePoisoning: Which he got from eating [[spoiler: cooked]] [[PsychoSerum red flowers.]]

A strange--if happy-go-lucky--monster under the command of the Doctor
* BaitAndSwitchBoss: After turning the power on in Grasstown, the robot Malco prepares to attack you. Then Balrog shows up and crushes him, commencing a boss fight.
* {{Bewitched Amphibian|s}}: On the third encounter with him, he gets transformed by Misery into [[AttackOfTheFiftyFootWhatever Balfrog]].
* BoisterousBruiser
* BullfightBoss: The first fight with him.
* TheBrute
* CatchPhrase: ''Huzzah!'' (or "Oh yeah!" in commercial English versions)
* TheCavalry: [[spoiler:In the good ending.]]
* DefeatMeansFriendship: Eventually.
* IncomingHam: ''Huzzah!''
* MacrossMissileMassacre: During the final encounter with him. Quite appropriately, you get an upgrade to rocket launcher after the battle.
* PsychopathicManChild: We don't actually know how old he is, but personality-wise the disconnect between the almost child-like way he carries himself and the monstrous things he does during the story qualifies him for this trope. For one thing, [[spoiler: during The Sand Zone part of the game you can come back to Jenka's house after getting the last dog for her and find the rest of them noticeably absent and Balrog gloating about having the key to the warehouse. [[FridgeHorror This could be seen as him killing her dogs as an interrogation method to make her give him the keys.]] For another he force-feeds Toroko red flowers, basically killing her.]]
* RecurringBoss: Fought 4 times throughout the first half of the game.
* SkippableBoss: The first fight with Balrog can be skipped by answering "no" when he asks if you're going to fight him.
* StoneWall: He isn't particularly fast or dangerous damage-wise, but considering how often you fight him and how much punishment he can take makes him qualify.

A young witch under the command of the Doctor.
* BossBonanza: With the Doctor and [[spoiler: the Undead Core.]]
* TheDragon
* DemonicPossession: Is possessed by the Doctor in the final battle.
* EvenEvilHasStandards: Basically the way that she reacts when the Doctor [[spoiler: cheats death.]]
* EvilAlbino
* HeelFaceTurn: Appears to undergo one in the end, due to the Doctor betraying her.
* LaserGuidedKarma:
** In the normal ending: [[spoiler:So the Doctor is not as dead as you thought, and is now an omnipotent {{Energy Being|s}} of pure evil? Clearly, the best course of action is to [[BullyingADragon attack him in frustration!]]]]
** The voice in the Sacred Grounds reveals that [[spoiler:she's the one who created the Demon Crown in the first place. As Balrog points out in the ending, this makes her enslavement to whoever wears it a lot less sympathetic.]]
* NamesToRunAwayFromReallyFast
* TheStarscream: Heavily implied to have been one for her uncle Ballos.
* UnexplainedRecovery: From her DemonicPossession, in the credits.
* VillainTeleportation
* YouGottaHaveBlueHair: She has blue hair on her sprites and green hair on portraits.

!!The Doctor (full name: [[spoiler:Dr. Fuyuhiko Date]])
The cruel tyrant of the island. [[spoiler: Formerly the research group's medic, he discovered the Demon Crown and went mad with power.]]
* BigBad
* BossBonanza: With Misery and [[spoiler:the Undead Core]].
* EveryoneCallsHimBarkeep: His real name is subtly revealed after defeating the Heavy Press.
* EvilGenius
* EvilIsNotAToy: [[spoiler:It looks like he gets his KarmicDeath in his boss fight this way... [[AvertedTrope then he possesses the island's Core.]]]]
* FourEyesZeroSoul
* MorallyAmbiguousDoctorate
* ScaryShinyGlasses
* SequentialBoss: Courtesy of a SuperPowerMeltdown.
* SuperPowerMeltdown: [[EnergyBeings Pays off]] [[DrunkOnTheDarkSide in the end.]]
* TakeOverTheWorld: His ultimate goal.
* TeleportSpam: A tactic that he relies ''way'' too much on during the first phase of the boss battle against him.
* VillainTeleportation

[[folder:Important Characters]]
A young Mimiga and Sue's friend.
* BlushSticker: Two permanent ones.
* RidiculouslyCuteCritter: As with all Mimigas.
* SacrificialLamb
* ShootTheDog: And... no, there's nothing the player can do to prevent this.
* TragicMonster: Happens due to being [[spoiler:force-fed demonic flowers.]]
* UncannyFamilyResemblance: To [[NumberTwo Jack,]] of all people.

!!Kazuma Sakamoto
Sue's older brother.
* ButtMonkey: He is mostly seen trapped in a warehouse whining, and his younger sister Sue beats the crap out of him often.
* DirtyCoward: Of all the characters, Kazuma is the most cowardly. At the beginning of the game, he's begging for help from his little sister, who is in actual danger. [[spoiler:Near the endgame, he decides to abandon the island, leaving behind his sister and the rest of his companions. Accepting his offer to go with him leads to the game's worst ending.]]
* DistressedDude: He's first met locked up inside a Grasstown shelter.
* EyesAlwaysShut
* MrFixit
* PointlessBandAid
* YouGottaHaveBlueHair: Has green hair.

An old lady who lives in the Sand Zone. She has five lost puppies, and requests that the hero [[FetchQuest find them for her]].
* ChekhovsGunman: She is [[spoiler:Ballos' sister, and the one who sealed him away after he went out of control]]. She is also [[spoiler:Misery's mother]].
* MiniatureSeniorCitizens: She's the same height as the hero, who's half the height of most humans.
* RetiredBadass: Again, she sealed Ballos, assuming he was powerful back then as well, that must have required really strong magic.

A cowardly engineer transformed into a Mimiga.
* BalefulPolymorph: Transformed into a Mimiga by Misery.
* CowardlyLion

!!Professor Booster
The former research party's technician.
* JetPack: He gives one to you over the course of the game.
* TheProfessor: Of course.
* RedHerringMole: Professor Booster appears as a grumpy-looking, old scientist in a white coat wearing opaque, signal red glasses. It doesn't help that the game's main antagonist throughout the story is also a doctor in a white coat. Nonetheless he never switches sides,  and even stays loyal until his death in one continuity of the game, giving away an item to the protagonist with his last bit of strength that he could otherwise have used to save himself.
* ViolationOfCommonSense: There is a point where he falls and gets major injuries. Ignore him completely [[spoiler:and he will come back alive and well with an improved Booster 2.0]].

!!Momorin Sakamoto
The mother of Sue and Kazuma.

!! Ballos
[[spoiler: Once Jenka's kind and loving brother, now a mad sorcerer trapped in the depths of the island.]]
* AmbidextrousSprite: Averted. His eyes keep proper colours no matter what direction he faces.
* AndIMustScream: [[spoiler: His powers are beyond even his control now, and has been living a long time with that in mind.]]
* {{Badass}}: [[spoiler: A very powerful individual, and the toughest boss in the game.]]
* BossBonanza: [[spoiler: Comes right after the Heavy Press.]]
* BeingTorturedMakesYouEvil
* DeathSeeker: [[spoiler: He waits for the person who can finally kill him and subdue his powers.]]
* EvilIsBurningHot
* GreaterScopeVillain: [[spoiler: While not directly commanding the Doctor, he created the Demon Crown, and as long as he's alive, the Demon Crown will always regenerate after being destroyed.]]
* HatePlague
* ICannotSelfTerminate: [[spoiler: The last thing he says to you before his death is "Now kill me... or I... shall kill you!"]]
* LightningBruiser: [[spoiler: He's very tough, deals a lot of damage, and surprisingly fast for his size in all forms.]]
* LoadBearingBoss: Inverted. [[spoiler: His magic is what's pulling the island down after the Core has been destroyed. Killing him causes the island to stop falling. Played straight when the walls of the room you fight him in start to close together after you beat him.]]
* NiceGuy: [[spoiler: Used to be one. His sincerity and unfailing devotion to helping out his fellow people are what led to his jealous king sentencing him to [[ColdBloodedTorture insanity-inducing torture]].]]
* OneWingedAngel: [[spoiler: His last form is a giant ball with his face on it, with the eyes and mouth [[BodyHorror covered in screaming red faces]]]]
* SequentialBoss: [[spoiler: You face his default form, then a giant version of his head, and finally a giant ''bloody'' version of his head.]]
* TrueFinalBoss: [[spoiler: You only face him at the end of the "True Ending" route.]]
* WalkingSpoiler
* WoobieDestroyerOfWorlds

A frenzied Mimiga. He kidnaps Sue in the Egg Corridor. It is implied he was the caretaker of the Dragon Eggs, as the 3DS version reveals the ID Card is his.
* DegradedBoss: Reappears on The Balcony as a slightly stronger regular enemy, jumping higher and firing off more projectiles. Whether it's actually him, or just another frenzied Mimiga that looks and acts like him is up for debate.

A robotic monster that lives in the Sand Zone. Prior to its appearance, Misery was going to fight the hero. Upon noticing him about to rise from the sand, she leaves dealing with the hero to him.
* BaitAndSwitchBoss: Misery's the bait, Omega's the switch.

!!Pooh Black
A "ghost" that haunts an old clinic in the labyrinth.
* KaizoTrap: After killing him, it is still possible to take damage and even die if you touch his remaining bubbles.
* PaletteSwap: Of Balrog, for the most part. There are subtle differences between Balrog's sprite and Pooh Black's.
* SpellMyNameWithAnS: His name is sometimes spelled "Puu Black."

!!Monster X
A large "X" shaped tank that appears in the Labyrinth. Upon defeating it, the player can see who was driving it: [[spoiler:A cat.]]
* BullfightBoss
* CoresAndTurretsBoss
* CuteKitten: The cat is there purely for laughs.
* MeaningfulName: It ''is'' shaped like an X.

!!The Core[[spoiler:/Undead Core]]
A large, multi-segmented monster that lives in the center of the island. Its power [[spoiler:keeps the island floating in the air. If it is destroyed, the island will fall. After defeating it the first time, it's about to be destroyed, but Misery and the Doctor arrive and save it. It becomes the Undead Core and is a possible Final Boss]].
* BossBonanza: In the second fight, it comes after Misery and the Doctor.
* ClimaxBoss: The second fight. If you don't meet the qualifications for the True Ending, though it becomes the FinalBoss
* DiscOneFinalBoss: The first fight.
* FinalBoss: Its second fight is this for the Normal ending.
* LoadBearingBoss: It ''is'' [[spoiler:keeping the island floating in the sky. More specifically, it keeps Ballos's magic from making the island fall. Misery is understandably ''[[WhatTheHellHero pissed off]]'' at you when you almost [[NiceJobBreakingItHero destroy it]] for the first time.]]
* NightmareFace: Is TheFaceless during it's first battle but when [[spoiler: The Doctor possesses it]], it gains a few nasty looking faces indicating when it's vulnerable and what attack it's going to use.
* UnderwaterBossBattle: In the first fight, it can raise the water level in the chamber in an attempt to make you drown.

A masked fish that lurks in the Waterway.
* TheCameo: Ironhead is a character from [[SwimIkachan one of Studio Pixel's earlier games]].
* FlawlessVictory: Defeat him without getting hurt and you will get an [[CosmeticAward Alien Badge]] and [[TheCameo see a bunch of squid swim across the screen]].
* GiantSpaceFleaFromNowhere
* UnderwaterBossBattle
* UnexpectedShmupLevel: During the battle with him.

!!The Sisters
A pair of dragons that attack the hero if he decides to pick up the missile upgrade in the [[spoiler:destroyed Egg Corridor]].
* BonusBoss: The only reason to fight them is to get a rocket ammunition which is purely optional.
* DualBoss
* EmptyRoomUntilTheTrap
* SkippableBoss

!!Ma Pignon
A mischievous mushroom that lives in Mimiga Village's graveyard. He gives the hero the Mushroom Badge if he [[spoiler:saves Curly and tells him about her amnesia. The badge itself does nothing; the actual cure is Ma Pignon himself. However, he won't go down without a fight]].
* BonusBoss: [[spoiler:Required in order to get the best ending]].
* {{Jerkass}}
* LetsMeetTheMeat

!!The Red Demon (a.k.a. The Red Ogre)
A red monster that appears in [[spoiler:Last Cave (Hidden)]]. It's implied that this is the creature that Arthur drove away from Mimiga Village.
* BonusBoss
* ChekhovsGunman: Briefly mentioned earlier in the game.
* GiantSpaceFleaFromNowhere: Barely averted, since he gets a mention. His appearance in [[spoiler:the Last Cave (Hidden)]] is rather sudden, though.
* PaletteSwap: Of the generic enemy Droll.
** The plus version takes it a step further and gives him a headswap as well, making him look more like an actual demon.
* SpamAttack: Like the Drolls he throws blades, but he throws three at a time, pause, then three more, rinse and repeat.

!!Heavy Press
A giant Press. It appears as a boss in [[spoiler:[[BrutalBonusLevel Sacred Grounds]]]].
* BossBonanza: [[spoiler:With Ballos.]]
* KaizoTrap: Heavy Press falls through the floor after being killed. The punishment for standing underneath him when he does so is instant death. That is, unless you abuse MercyInvincibility via one of his minions.
* KingMook
* StationaryBoss

[[spoiler: A mysterious machine within the Wind Fortress that produces clones of Curly.]]
* AIBreaker: The Mooks it spawns won't attack you when you stand on the block at the very left.
* BonusBoss: Boss of the Wind Fortress.
* MookMaker: [[spoiler: Curly clones]], to be precise.

Mimiga Village's second-in-command. He guards the entryway to the graveyard.
* CharacterTic: Pointing at people. [[WhyAreYouLookingAtMeLikeThat Also staring at them.]]
* HatOfAuthority
* HypercompetentSidekick: He's surprisingly the only member of the Jack/Toroko/King trio that quite possibly didn't die during the game.
* NerdGlasses
* NiceHat
* NumberTwo
* WhatHappenedToTheMouse: The last time he can be seen is in a Plantation prison. He disappears completely without a word thereafter.

A resident of Grasstown. He lost his key, so he asks the hero to find it for him.
* MalevolentArchitecture: His house comes complete with a spike-trap you can fall into for no other reason than to warn players.
* OneMarioLimit: Averted.
* SchmuckBait: Said spike-trap comes with a very obvious warning.
-->Watch out! Deathtrap to your left! [[ChunkySalsaRule One touch means instant death!]]
* StealthPun: A necessary bomb ingredient, [[spoiler:charcoal]], its found in his house.

A resident of Grasstown. The fireplace in her house contains a passageway that leads to the second half of Grasstown.
* EventFlag: To pass through the fireplace, you need a jellyfish juice. Said jellyfish juice comes from a giant jellyfish that appears only when you try to pass through the fireplace.
* OptionalSexualEncounter: Sleep in her bed after she mentions jellyfish juice, and the hero will wake up with her sleeping next to him. He obtains her lipstick, which is useless outside of getting HundredPercentCompletion. [[spoiler:This also works in Curly Story. She gets her rouge.]]
** {{Bowdlerization}}: [[spoiler: Thankfully, it's an amusing example of this trope. Sleep in her bed in the 3DS remake, and you'll wake up to find her sleeping on the floor. You'll still get her lipstick, though.]]

A robot that oversees the power room in Grasstown. He helps break Kazuma out of a house.
* MacGyvering: He can make a bomb out of charcoal, gum, and jellyfish juice.
* RoboSpeak: In the fan-translation he SPEAKS IN ALL-CAPS ALL THE TIME.
* TinCanRobot
