Main Characters
Mister Traveler/Quote

The Playable Character. An amnesiac who awakes in a small cave in the depths of a strange island.
- Accidental Pervert: He can optionally find 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: They unlock Curly as a playable character.
- Amnesiac Dissonance: It's eventually revealed that he was one of many robots sent from the surface to kill the Mimiga and claim the Demon Crown. Subverted if you restore Curly's memories, when she remembers that the two of them were made to destroy the Demon Crown, so he's actually doing what he was made for after all.
- Amnesiac Hero: He has no memory of his name or original mission at all. 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.
- Army Scout: He is revealed to be one of these by Professor Booster.
- But Not Too Foreign: Sue Sakamoto was unable to decipher the English text
written on his hat.
The impact of this is mostly Lost in Translation, since the English localizations aren't in Japanese. It's likely Mister Traveler was intended to be an American. This is further supported by his main gun, which is shown to be a revolver in all of the official
artwork.
- The Drifter: An interesting case. His lack of memory leaves him with nowhere specific to go, and he spends his time randomly drifting from one area to the next and assisting everyone he finds. The result is essentially a Knight Errant.
- Force and Finesse: Mister Traveler is implied to be the "Finesse" to Curly Brace's "Force", even though gameplay tends to contradict it. The official
◊ artwork
◊ consistently
◊ shows
their preferred weapons to be a revolver and machine gun, respectively
◊. It's also worth noting that Mister Traveler is The Quiet One and Curly Brace is a Genki Girl.
- The Gunslinger: Of the Vaporizer variety. Mister Traveler carries a huge variety of highly improbable guns and enough ammunition to obliterate a super-tank supported by various mooks.
- Heroic Albino: He is stark white. It's not actually skin, but probably some kind of polymer.
- Heroic Mime: During the main game, Mister Traveler almost never says anything, but characters often react as if he had. This implies that his dialogue is possibly meant to be imagined by the player. However, he does make player-selected Yes/No responses to questions, and at one point speaks a verbal password. When you're playing as Curly, he only talks out loud exactly once, implying instead that he normally just doesn't talk.
- Hyperspace Arsenal: He can carry vast amounts of weaponry.
- Lightning Bruiser: Very nimble (especially with the Booster upgrades), wields plenty of powerful weapons, and can potentially survive a lot of damage with sufficient Health upgrades.
- Nice Hat: A baseball cap.
- No Name Given: He's only referred to as Mister Traveler in official media, and only because Chako asks him if he is a traveler. His name is "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).
- The Quiet One: During the main game, Mister Traveler almost never says anything, but characters often react as if he had, implying that dialogue is possibly meant to be imagined by the player. However, he does make player-selected Yes/No responses to questions, and at one point speaks a verbal password. When you're playing as Curly, he only talks out loud exactly once, implying that he normally just doesn't talk.
- Red and Black and Evil All Over: With that red hat and black shirt, you start off with everyone thinking you are a battle robot from the surface sent to kill the Mimiga. The fact that you ''are'' a robot soldier, (and stark white) doesn't help. Subverted later on when you learn that you were sent to destroy the Demon Crown rather than the Mimiga.
- Ridiculously Human Robots: As we learn from Professor Booster, he is an armed scout robot, despite his human-like limitations.
- Robot Soldier: Several non-player characters remark to Mister Traveler that he is a "soldier from the surface". As it turns out, all such soldiers were robots. Specifically, he's an armed scout robot. This is made jarring by how amazingly human he is.
- Savvy Guy, Energetic Girl: Mister Traveler is The Quiet One and the official artwork seems to indicate he is on The Stoic side. Conversely, Curly is an upbeat Genki Girl.
- Scarf Of Asskicking: He always wears a green scarf.
- Series Mascot: Alongside Balrog.
- Sword and Gun: Once the player acquires the Blade, this trope comes into play thanks to Hyperspace Arsenal (since he can switch weapons instantly). Some of the official artwork deliberately invokes this
.
- Theme Naming: Quote marks " are widely used in programming software. He shares this theme with Curly Brace: Curly Braces { } are also widely used in programming software.
- Unusual Ears: His ears are Robot Antennae.
- Weapon of Choice: The official artwork indicates that his favorite gun is the Polar Star handgun.
Curly Brace
Mimiga Ally

- Action Girl: Like Quote, she's a robot sent from the surface to destroy the Demon Crown.
- Army Scout: Just like Mister Traveler.
- Badass Adorable: About as cute you can be for a deadly robot.
- Back-to-Back Badasses: 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.
- Contractual Boss Immunity: Aside from preventing drowning, her bubble tank also grants her a Deflector Shield that makes her immune to the otherwise overpowered missiles.
- Defeat Means Friendship: The first time the player meets her, she thinks he's there to kill the Mimiga. After defeating her, she actually listens to him, and puts her weapons down.
- Force and Finesse: Curly Brace is implied to be the "Force" to Mister Traveler's "Finesse", even though gameplay tends to contradict it. The official
◊ artwork
◊ consistently
◊ shows
their preferred weapons to be a revolver and machine gun, respectively
◊. It's also worth noting that Mister Traveler is The Quiet One and Curly Brace is a Genki Girl.
- Gameplay Ally Immortality: During the segment in the Labyrinth where she fights alongside the protagonist, she is completely invincible. She can even walk through spikes.
- Genki Girl: Upbeat is pretty much her default mood.
- Guest-Star Party Member: During the second half of the Labyrinth.
- The Gunslinger: Just like Mister Traveler.
- Heroic Sacrifice: 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.
- Let's You and Him Fight: Attacks the player character almost immediately after he meets her.
- Lightning Bruiser: Just like Mister Traveler. she's the same sort of scout robot as Quote, and thus has exactly the same abilities as he does.
- More Dakka: Her Machine Gun, which she'll offer to you after beating her; she takes the Polar Star in return.
- Nice Girl: She and Mister Traveler have a little 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. She also sacrifices herself to keep you alive for no reason other than that she wanted to.
- Ridiculously Human Robots: She can eat and digest food, among lots of other little things.
- Robot Soldier: Just like Mister Traveler, she is an armed scout robot.
- Savvy Guy, Energetic Girl: While Curly is an upbeat Genki Girl, Mister Traveler is The Quiet One and the official artwork seems to indicate he is on The Stoic side.
- Small Girl, Big Gun: Curly's gun
seems to be about as big as her body.
- Super Not-Drowning Skills: Thanks to an oxygen tank that she carries around, an oxygen bubble forms around her every time she steps foot in water. She gives it to you after the Core fight.
- Unusual Ears: Just like Mister Traveler, her ears are Robot Antennae.
- Theme Naming: Curly Braces { } are widely used in programming software. She shares this theme with Mister Traveler, whose real name is Quote: Quote marks " are also widely used in programming software.
Sue Sakamoto
Looks up to her brother

- Badass Boast: Gives one before fighting Igor. She fearlessly tells him to "Bring it on!" and that she's stronger than her brother. However, that doesn't mean much as said brother isn't particularly strong, and unfortunately it doesn't end well for her...
- Baleful Polymorph: Got shapeshifted into a mimiga thanks to Misery.
- Demonic Possession: By the Doctor in the final battle. Temporary, fortunately.
- Distressed Damsel: On several occasions.
- Does Not Like Shoes: Mimiga are normally barefoot (and pantless), including humans transformed into them. However, an ending scene shows her and Itoh being turned back into humans (briefly), and while Itoh regains his shoes from this, Sue doesn't, implying she was barefoot even before being a Mimiga.
- Faux Action Girl: Just as she encounters a frenzied mimiga, she brags about how she defeated Kazuma in a fight (which isn't saying much). Cue No-Holds-Barred Beatdown.
- Multi-Ethnic Name: Yet her relatives both have Japanese given names.
- Promoted to Playable: The Nintendo Switch version upgrades her status to playable for a second player.
- 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.
- You Gotta Have Blue Hair: Her true hair is green.
- "X" Marks the Hero: Has an X-mark over her nose. It's even visible in her human form.
King
The Leader
The leader of the Mimiga village and Toroko's brother-figure.- Always Someone Better: While he is a very powerful warrior, Arthur is always implied to be stronger and more celebrated. King is also said to be trying to prove he is just as strong.
- Big Brother Instinct: He's very protective towards Toroko.
- Backup from Otherworld: The fully upgraded Blade is less Mister Traveler launching Sword Beams, and more King's spirit swiping at anything he's targeting.
- Cool Sword: And he passes it onto your hands after taking a fatal blow from The Doctor.
- Face of a Thug: He certainly looks rather sinister, but he's a case of Good Is Not Nice at worst.
- Glass Cannon: He beats Balrog, who is a Stone Wall, in a single blow. However, all it took was a single hit from The Doctor to defeat him.
- Good Scars, Evil Scars: Has a nasty scar on across his face, which adds more to his Face of a Thug, but he's unarguably good.
- I'll Kill You!: Utters this to Doctor when he meets him.
- Not Too Dead to Save the Day: 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.
- Red Eyes, Take Warning: Subverted in that he's a good guy regardless of this trope applying for him. This is because
Pixel confirmed that King indeed ate red flowers, but cooked them, which gave him strength but didn't turn him.
- Sacrificial Lion: Is the leader and strongest resident of the Mimiga Village, but is killed off in the Sand Zone.
- Testosterone Poisoning: Which he got from eating cooked red flowers.
Balrog
Misery's punching bag

- Bait-and-Switch Boss: After turning the power on in the Bushlands, the robot Malco prepares to attack you. Then Balrog shows up and crushes him, commencing a boss fight.
- Bewitched Amphibian: On the third encounter with him, he gets transformed by Misery into Balfrog.
- Boisterous Bruiser: Big time.
- Bullfight Boss: During the first fight with him.
- The Brute: Acts as this towards the Doctor.
- Catchphrase: Huzzah! (or "Oh yeah!" in commercial English versions)
- The Cavalry: In the good ending, when he saves Quote and Curly Brace from Ballos' Seal Chamber.
- Defeat Means Friendship: Eventually. After all, he doesn't even want to follow the Doctor's plans, though he has no choice.
- HeelFace Turn: In the good ending, he and Misery are freed from the Doctor's influence, which leads to Balrog pulling a Big Damn Heroes to save Quote and Curly from Ballos' Seal Chamber closing in on them.
- Forced into Evil: He's forced to obey whoever wears the Demon Crown. When freed, he quickly pulls a HeelFace Turn.
- Incoming Ham: Huzzah!
- Just Following Orders: Overlaps with Forced into Evil.
- Living Weapon: He is one for whoever wears the Demon Crown.
- Macross Missile Massacre: During the final fight with him. Quite appropriately, you get an upgrade to rocket launcher after the battle.
- Names to Run Away from Really Fast: Sounds like a name worthy of Demon Lords and Archdevils.
- Psychopathic Manchild: 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, 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.
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.
- Recurring Boss: Fought four times throughout the first half of the game.
- Skippable Boss: The first fight with Balrog can be skipped by answering "no" when he asks if you're going to fight him.
- Stone Wall: 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.
Misery
The Doctor's servant
A young witch under the command of the Doctor.- Baleful Polymorph: Has a penchant for this. She transformed Sue and Itoh into Mimiga, and Balrog into Balfrog.
- Boss Bonanza: With the Doctor and the Undead Core.
- Claimed by the Supernatural: When she made Ballos create the Demon Crown, he responded by forcing her to serve whoever wears it.
- The Dragon: Technically shares this role with Balrog, but she's by far the most proactive of the two.
- Demonic Possession: Is possessed by the Doctor in the final battle.
- Even Evil Has Standards: Basically the way that she reacts when the Doctor cheats death.
- Evil Albino: Though she lacks the white hair.
- Familiar: She's unwillingly bound to the wearer of the Demon Crown.
- Forced into Evil: She's forced to obey whoever wears the Demon Crown. When freed, she quickly pulls a HeelFace Turn.
- HeelFace Turn: Appears to undergo one in the end, due to the Doctor betraying her. In the good ending, it's revealed that she sent Balrog to rescue Quote and Curly Brace from the Seal Chamber the moment Ballos was destroyed. Due to the fact that the Demon Crown can no longer regenerate now that he's dead, she doesn't have to follow orders from anyone else, and so she underwent a real HeelFace Turn.
- Jerkass: As a recurring enemy throughout the story, she's directly responsible for sending multiple characters (including Balrog) to the Labyrinth, and clearly enjoys some of her moments of reveling in what she does. The fact that she had the Demon Crown made in the first place cements this further, albeit with a case of Laser-Guided Karma. The best ending reveals her to be a Jerk with a Heart of Gold, however, when she near-immediately sends Balrog to save Quote and Curly from Ballos' chambers.
- Karmic Transformation: For someone with a penchant for Baleful Polymorphs, it's fitting that she gets turned into a vaguely amphibious/reptilian form.
- Just Following Orders: Overlaps with Forced into Evil.
- Laser-Guided Karma:
- So the Doctor is not as dead as you thought, and is now an omnipotent Energy Being of pure evil? Clearly, the best course of action is to attack him in frustration!
- The voice in the Sacred Grounds reveals that 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.
- Living Weapon: She is one for whoever wears the Demon Crown.
- Names to Run Away from Really Fast: Her name is Misery, for crying out loud.
- The Starscream: Heavily implied to have been one for her uncle Ballos.
- Unexplained Recovery: From her Demonic Possession, in the credits.
- Villain Teleportation: She sure loves to Teleport Spam during her boss fight.
- You Gotta Have Blue Hair: She has dark blue hair on her sprites and green hair on portraits, though later releases changed her hair in portraits to blue.
The Doctor/Dr. Fuyuhiko Date
The power-snatching betrayer
The cruel tyrant of the island. Formerly the research group's medic, he discovered the Demon Crown and went mad with power.- Ax-Crazy: He wants to get an army of Mimiga together and hype them up on the Demon Flowers, creating his own personal army through which he'll rule the world amidst destruction. To this end, he's more than willing to kill anyone and everyone in his way, including his own associates once he has no more use for them.
- Badass Longcoat: Downplayed. After you beat the first phase of your battle against him, he loses control of his power, goes berserk, and his long lab coat gets torn apart.
- Big Bad: The primary antagonist of the story.
- Boss Bonanza: With Misery and the Undead Core.
- Deader Than Dead: His soul is destroyed while fused with the Undead Core.
- Everyone Calls Him "Barkeep": His real name is subtly revealed after defeating the Heavy Press.
- Evil Genius
- Evil Is Not a Toy: It looks like he gets his Karmic Death in his boss fight this way... then he possesses the island's Core.
- Faux Affably Evil: He is very formal and polite, and absolutely psychotic.
- Four Eyes, Zero Soul
- Morally Ambiguous Doctorate: In fact, he was the medical doctor working with the research team.
- Scary Shiny Glasses
- Sequential Boss: The boss fight against him has three stages.
- Smug Snake: The Doctor has only one portrait, and it's got a smug smile that oozes with his Faux Affably Evil nature and extreme confidence in his superiority.
- Super-Power Meltdown: Pays off in the end.
- Take Over the World: His ultimate goal.
- Teleport Spam: A tactic that he relies way too much on during the first phase of the boss battle against him.
- Villain Teleportation
Important Characters
Arthur
A Mimiga warrior, and Toroko's brother. He was killed by the Doctor.
- 100% Adoration Rating: All of the Mimiga think the world of him.
- Posthumous Character: He died before the events of the game.
Toroko
Nice and Courageous

- Beware the Nice Ones: She's a sweet girl normally, but when force-fed the Red Flower, she turned into a frenzied Mimiga bigger, faster and stronger than others.
- Blush Sticker: Two permanent ones.
- Nice Girl: She's extremely friendly and loyal.
- Ridiculously Cute Critter: Somehow even moreso than your average Mimiga.
- Killed Off for Real: And by the player's own hand, no less.
- Shoot the Dog:
Sadly, there's nothing the player can do to prevent this.
- Tragic Monster: Happens due to being force-fed demonic flowers.
- Uncanny Family Resemblance: To Jack, of all people.
Kazuma Sakamoto
Sometimes reliable brother
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 Bushlands shelter.
- Eyes Always Shut: Both in his overworld sprite and portrait.
- Mr. Fixit
- Pointless Band-Aid: Has one on his left cheek.
- You Gotta Have Blue Hair: Has green hair.
Jenka
Keeper of the Sand Zone
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
The Mimiga-like coward engineer
A cowardly engineer transformed into a Mimiga.- Baleful Polymorph: Transformed into a Mimiga by Misery.
- Cowardly Lion: Eventually overcomes his fear to help Momorin construct the escape rocket.
- Mr. Fixit: He's an engineer.
Professor Booster
Sue's grandfather figure
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
Sue's mom
The mother of Sue and Kazuma.- Deadpan Snarker: Momorin's commentary on the Doctor trying to throw her off the island once she's done her job for him is to dryly retort about how "chivalry is dead, let me tell you," or to snark about how it was "not very nice" in the Nicalis translation. Sue definitely got a bit of her attitude from Momo.
- Mama Wolf: Not that she could personally do anything about it herself, but Momorin does take particular offense to the Doctor taking Sue with intent to feed her red flowers with the rest of the Mimiga. Consequently, she near-immediately sends the One-Man Army that is Mister Traveler right to the Doctor's doorstep.
- You Have Outlived Your Usefulness: The Doctor had Momorin tossed off the side of the island not long after the group's arrival, once she confirmed the existence and location of the red flowers. Somehow she survived just fine and snuck her way into the Plantation anyway, helping Mister Traveler directly in reaching the Doctor as a bit of payback.
- You Gotta Have Blue Hair: Green, just like her son Kazuma and the human form of her daughter Sue.
Ballos
Once Jenka's kind and loving brother, now a mad sorcerer trapped in the depths of the island.
- Ambidextrous Sprite: Averted. His eyes keep proper colors no matter what direction he faces.
- And I Must Scream: His powers are beyond even his control now, and has been living a long time with that in mind.
- Badass Longcoat: Wears one during the first phase of your battle against him, and just like the Doctor, loses it at the second phase of the battle.
- Boss Bonanza: Comes right after the Heavy Press.
- Being Tortured Makes You Evil: he was tortured until his massive magic reserves exploded and destroyed the city he loved. His mind couldn't take the strain. Since that moment, he's been a danger to himself and everyone else.
- Death Seeker: He waits for the person who can finally kill him and subdue his powers.
- Evil Is Burning Hot
- Greater-Scope Villain: While he's 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.
- Hate Plague: His rage and insanity, coupled with his out-of-control powers, causes both the Demon Crown and Demon Flowers to exist.
- I Cannot Self-Terminate: The last thing he says to you before his death is "Now kill me... or I... shall kill you!"
- Lightning Bruiser: He's extremely tough, deals a lot of damage with each hit, and surprisingly fast for his size in all forms.
- Load-Bearing Boss: Inverted. 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.
- Mad God: Driven insane by the brutal torture his king subjected him to, he now lies within the island as his infinite powers continue to grow, waiting for someone to kill him (while he also tries to kill them). His powers have grown far out of his control and, coupled with his rage, have created a number of dangerous objects around the island as well as constantly pulling the island downwards.
- Nice Guy: 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 insanity-inducing torture.
- Nightmare Face: His last form is a giant ball with his face on it, with the eyes and mouth open, vacant, and filled with screaming red faces. It only gets worse in Halloween Mode.
- Physical God: He possesses power far beyond normal beings.
- Sequential Boss: You face his default form, then a giant version of his head, and finally a giant bloody version of his head.
- Shock and Awe: One of his attacks is to rain down lightning bolts.
- The Ageless: He cannot die naturally, instead needing someone to kill him.
- True Final Boss: You only face him at the end of the "True Ending" route.
- Walking Spoiler
- Woobie, Destroyer of Worlds
Bosses
Igor
Rabid Mimiga who kidnapped Sue
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: An identical frenzied Mimiga appears on The Balcony as a slightly stronger regular enemy, jumping higher and firing off more projectiles.
Omega
Machine-monster that lurks in the sand
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.- Bait-and-Switch Boss: Misery's the bait, Omega's the switch.
Puu Black
Ghost in the clinic
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 Puu Black's.
- Spell My Name with an "S": His name is spelled "Pooh Black" in the Aeon Genesis
Fan Translation.
Monster X
Big boss in the labyrinth
A large "X" shaped tank that appears in the Labyrinth. Upon defeating it, the player can see who was driving it: A cat.- Bullfight Boss
- Cores-and-Turrets Boss
- Cute Kitten: The cat is there purely for laughs.
- Meaningful Name: It is shaped like an X.
The Core/Undead Core
Heart of the island
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
Big fish in the island's artery
A masked fish that lurks in the Waterway.- The Cameo: Ironhead is a character from one of Studio Pixel's earlier games.
- Flawless Victory: Defeat him without getting hurt and you will get an Alien Badge and see a bunch of squid swim across the screen.
- Giant Space Flea from Nowhere
- Underwater Boss Battle
- Unexpected Shmup Level: During the battle with him.
The Sisters
Twin dragon surprise attackers
A pair of dragons that attack the hero if he decides to pick up the missile upgrade in the destroyed Egg Corridor.- Bonus Boss: The only reason to fight them is to get a rocket ammunition which is purely optional.
- Dual Boss
- Empty Room Until the Trap
- Skippable Boss
Ma Pignon
A tasty mushroom
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.- Bonus Boss: Required in order to get the best ending.
- Jerkass
- Let's Meet the Meat: The "I want to live!" kind.
The Red Ogre/The Red Demon
True heroes meet the...
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 by Jack in an optional dialogue in the Assembly Hall earlier in the game.
- Giant Space Flea from Nowhere: Barely averted, since he gets a optional mention. His appearance in the Last Cave (Hidden) is rather sudden, though.
- Oni: What his design is based off of. His original Japanese name is even Akaoni (red oni).
- Palette Swap: Of the generic enemy Droll.
- The plus version takes it a step further and gives him a Head Swap 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
The swollen mech
A giant Press. It appears as a boss in Sacred Grounds.- Boss Bonanza: With Ballos.
- Kaizo Trap: Heavy Press falls through the floor after being killed. The punishment for standing underneath it when it does so is instant death. That is, unless you abuse Mercy Invincibility via one of his minions.
- One-Hit Kill: If you don't step out of the way as it falls through the floor after defeat, you will die instantly.
- King Mook
- Stationary Boss
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. Naked ones, at that, which attack by grappling you
Other
Jack
Number-Two
Mimiga Village's second-in-command. He guards the entryway to the graveyard.- Character Tic: Pointing at people. Also staring at them.
- Hat of Authority: Seems to be
a Russian styled military hat
◊, with a chevron.
- Hypercompetent Sidekick: He's surprisingly the only member of the Jack/Toroko/King trio that quite possibly didn't die during the game.
- Nerd Glasses
- Nice Hat
- Number Two: Identifies himself as such.
- What Happened to the Mouse?: The last time he can be seen is in a Plantation prison. He disappears completely without a word thereafter.
Santa
The cowardly loner
A resident of the Bushlands. He lost his key, so he asks the hero to find it for him.- Malevolent Architecture: His house comes complete with a spike-trap you can fall into for no other reason than to warn players.
- One Mario Limit: Averted.
- Schmuck Bait: Said spike-trap comes with a very obvious warning.Watch out! Deathtrap to your left! One touch means instant death!
- Stealth Pun: A necessary bomb ingredient, charcoal, its found in his house. He also gives a gift to the player in exchange for finding his key.
Chako
The colorful Mimiga

- Event Flag: To pass through the fireplace, you need a jellyfish juice. Said jellyfish juice comes from a giant jellyfish that appears only once you have tried to pass through said fireplace.
- Good Bad Girl: Unambiguously so. She's a very friendly character, and has not one reservation about sleeping with Mister Traveler immediately after meeting him.
- Interspecies Romance: She can sleep with Mister Traveler. Despite all appearances, Mister Traveler is a very human-like robot. As such, Chako sleeping with him is actually an example of another trope. She likely already knows.
- Optional Sexual Encounter: If Mister Traveler sleeps in her bed after she mentions the jellyfish juice, he will wake up with her sleeping next to him. He obtains her lipstick, which is useless outside of getting 100% Completion.
- Bowdlerization: In the 3DS remake, if Mister Traveler sleeps in Chako's bed, he'll wake up to find her sleeping on the floor instead of next to him. However, he still gets her lipstick, so someone was not paying full attention.
- Sherlock Scan: Implied. She can tell that Sue Sakamoto is a human despite the fact that she was magically changed into a Mimiga. She even claims "my eyes can't be fooled".
- Spell My Name with an "S": Chako in the official Nicalis translation, Chaco in the Aeon Genesis fan translation.
- The Power of Love: After the fight with the Muscle Doctor, talking to Chako repeatedly will cause her to compare Mister Traveler with Arthur. This will cause all of the caged Mimiga 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.
- You Gotta Have Blue Hair: Chako is purple, while every other Mimiga you encounter is white.
Malco
Power Supply Bot
A robot that oversees the power room in the Bushlands. He helps break Kazuma out of a house.- Because You Were Nice to Me: Despite his initial aggression, Malco helps Mr. Traveler after the latter helps him out.
- MacGyvering: He can make a bomb out of charcoal, gum, and jellyfish juice.
- Robo Speak: In the fan-translation he SPEAKS IN ALL-CAPS ALL THE TIME.
- Tin-Can Robot: He certainly gets crushed like one thanks to Balrog.
