    Main Characters 

Mister Traveler/Quote

The Playable Character. An amnesiac who awakes in a small cave in the depths of a strange island.

Curly Brace

A mysterious young woman who seems to know a bit about our hero.

Sue Sakamoto

A fiery young girl being pursued by the Doctor's henchmen.

King

The leader of the Mimiga village, and Toroko's brother-figure.

Balrog

A strange—if happy-go-lucky—monster under the command of the Doctor

Misery

A young witch under the command of the Doctor.

The Doctor (full name: Dr. Fuyuhiko Date)

The cruel tyrant of the island. Formerly the research group's medic, he discovered the Demon Crown and went mad with power.

    Important Characters 

Arthur

A Mimiga warrior, and Toroko's brother. He was killed by the Doctor.

Toroko

A young Mimiga and Sue's friend.

Kazuma Sakamoto

Sue's older brother.
  • Butt Monkey: He is mostly seen trapped in a warehouse whining, and his younger sister Sue beats the crap out of him often.
  • Dirty Coward: 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. 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.
  • Distressed Dude: He's first met locked up inside a Grasstown shelter.
  • Eyes Always Shut
  • Mr. Fixit
  • Pointless Band-Aid
  • You Gotta Have Blue Hair: Has green hair.

Jenka

An old lady who lives in the Sand Zone. She has five lost puppies, and requests that the hero find them for her.
  • All-Powerful Bystander: She's just as powerful as Ballos and could have killed him when he lost his mind, ending the drama before it began... but she couldn't bring herself to kill him.
  • Chekhov's Gunman: She is Ballos' sister, and the one who sealed him away after he went out of control. She is also Misery's mother.
  • Miniature Senior Citizens: She's the same height as the hero, who's half the height of most humans.
  • Retired Badass: Again, she sealed Ballos, assuming he was powerful back then as well, that must have required really strong magic.

Itoh

A cowardly engineer transformed into a Mimiga.

Professor Booster

The former research party's technician.
  • Jet Pack: He gives one to you over the course of the game.
  • The Professor: Of course.
  • Red Herring Mole: 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.
  • Violation of Common Sense: There is a point where he falls and gets major injuries. Ignore him completely and he will come back alive and well with an improved Booster 2.0.

Momorin Sakamoto

The mother of Sue and Kazuma.

Ballos

Once Jenka's kind and loving brother, now a mad sorcerer trapped in the depths of the island.

    Bosses 

Igor

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.
  • Degraded Boss: 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.

Omega

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.

Pooh Black

A "ghost" that haunts an old clinic in the labyrinth.
  • Kaizo Trap: After killing him, it is still possible to take damage and even die if you touch his remaining bubbles.
  • Palette Swap: Of Balrog, for the most part. There are subtle differences between Balrog's sprite and Pooh Black's.
  • Spell My Name with an "S": 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: A cat.

The Core/Undead Core

A large, multi-segmented monster that lives in the center of the island. Its power 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.
  • Boss Bonanza: In the second fight, it comes after Misery and the Doctor.
  • Climax Boss: The second fight. If you don't meet the qualifications for the True Ending, though it becomes the Final Boss
  • Disc One Final Boss: The first fight.
  • Final Boss: Its second fight is this for the Normal ending.
  • Load-Bearing Boss: It is keeping the island floating in the sky. More specifically, it keeps Ballos's magic from making the island fall. Misery is understandably pissed off at you when you almost destroy it for the first time.
  • Nightmare Face: Is The Faceless during it's first battle but when The Doctor possesses it, it gains a few nasty looking faces indicating when it's vulnerable and what attack it's going to use.
  • Underwater Boss Battle: In the first fight, it can raise the water level in the chamber in an attempt to make you drown.

Ironhead

A masked fish that lurks in the Waterway.

The Sisters

A pair of dragons that attack the hero if he decides to pick up the missile upgrade in the destroyed Egg Corridor.

Ma Pignon

A mischievous mushroom that lives in Mimiga Village's graveyard. He gives the hero the Mushroom Badge if he 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.

The Red Demon (a.k.a. The Red Ogre)

A red monster that appears in Last Cave (Hidden). It's implied that this is the creature that Arthur drove away from Mimiga Village.
  • Bonus Boss
  • Chekhov's Gunman: Briefly mentioned earlier in the game.
  • Giant Space Flea from Nowhere: Barely averted, since he gets a mention. His appearance in the Last Cave (Hidden) is rather sudden, though.
  • Palette Swap: 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.
  • Spam Attack: 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 Sacred Grounds.

G-Clone

A mysterious machine within the Wind Fortress that produces clones of Curly.
  • A.I. Breaker: The Mooks it spawns won't attack you when you stand on the block at the very left.
  • Bonus Boss: Boss of the Wind Fortress.
  • Mook Maker: Curly clones, to be precise.

    Other 

Jack

Mimiga Village's second-in-command. He guards the entryway to the graveyard.

Santa

A resident of Grasstown. He lost his key, so he asks the hero to find it for him.

Chaco

A resident of Grasstown. The fireplace in her house contains a passageway that leads to the second half of Grasstown.
  • Event Flag: 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.
  • Good Bad Girl: Unambiguously so. She's a very friendly character, and has not one reservation about potentially sleeping with Mister Traveler immediately after meeting him.
  • Optional Sexual Encounter: 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 100% Completion. This also works in Curly Story. She gets her rouge.
    • Bowdlerization: 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.
  • The Power of Love: After the fight with the Muscle Doctor, talking to Chaco repeatedly will cause her to compare Mister Traveler with Arthur. This will cause all of the caged Mimigas to generate hearts over their heads. They function as health packs, and they are the only way to regain health before fighting the Undead Core.

Malco

A robot that oversees the power room in Grasstown. He helps break Kazuma out of a house.
