Keita AonoThe main character. A 17 year old student who finds himself piloting the Neuronoid Kakuseijin with Hinoki. While panicky, socially awkward, and caught in circumstances way over his head, Keita manages to show enough courage and wit to survive.
- Action Survivor: When he's not piloting the Neuronoid. Episode 8 is a prime example of this - he spends nearly the entire episode running for his life. (And with good reason too - the majority of that episode takes place in a hospital full of Brainwashed and Crazy nurses with poisoned fingernails!)
- Ascended Fanboy: As a military and video game fan, Keita squees every time he sees any high tech device or military units. He also thinks it's cool to be piloting a mecha... until the horrors show up.
- Chekhov's Hobby: His interest in military craft proves useful in one episode. In general, he likes the idea of piloting a mode-changing mecha enough that he keeps doing it.
- Chivalrous Pervert: Yeah, he's a teen with girls on his mind, and isn't above ogling. But Keita manages to contain these tendencies and cares about his female companions.
- Accidental Pervert: It's not his fault when Asami falls on top of him, or that he unintentionally gropes someone. But Keita's not above enjoying it.
- Distressed Dude: The poor guy gets cornered so many times.
- Falling into the Cockpit: It's a Sunrise production - what did you expect?
- The Hero: He tries, but because he's barely a single step above The Everyman in a SF Horror setting...
- Hidden Depths: He may be jittery, geeky, somewhat pervy, and often needs saving. However, Keita shows great bravery, thinks fast, keeps Hinoki from falling into despair, and manages to protect others in danger. It's only when there is no way out that Keita needs to be saved by someone else.
- It also comes out that, despite some Book Dumb tendencies, Keita is really good at figuring out effective uses of the Synapse Dangeki.
- Nice Guy: Despite his flaws, Keita is generally likable. It helps that he keeps putting his neck on the line for his friends.
- Non-Action Guy: Keita is what you would call... a loaner hero that you use until the real one shows up. At the same time, it doesn't matter what you throw at him, in the Kakuseijin or out of it, he'll keep getting right back up to fight.
- Right Man in the Wrong Place: Why he ends up piloting the Kakuseijin. Also happens outside the mech, such as Episode 8. After discovering the hospital's dark secret, he's the only one that can save Sakura.
- Tears of Fear: Played for laughs - Sometimes during an Oh, Crap! moment, Keita will shift into a silly crying expression before getting a hold of himself.
- Weirdness Magnet: Somehow, someway, he finds himself being confronted by strange monsters or visions. It turns out his Dual-kind capabilities plus the visions are the result of a dura matter transplant when he was younger.
- What the Hell, Hero?: Hinoki gets peeved when Keita runs away from a situation, leaving her behind.
- In another episode, Keita does this to Akamatsu and himself after they get separated from Hinoki and Li-chan. Unable to get back to them, a distraught Keita points out how pathetic it is that "the men ran off and left the women behind".
- Wrong Genre Savvy: After entering the Kakuseijin in Episode 1, Keita begins to make assumptions based on Real Robot Mecha Shows. He gradually realizes that he's in Survival Horror where the Kaiju is the real hero.
Hinoki SaiKeita's classmate and co-pilot of the Kakuseijin, as well as his childhood friend. After her parents and brother Mario went missing, she became melancholy and distant. As a Head Diver, she is apparently very good at synthesizing particles for the Synapse Dangeki.

- Anime Hair: Her multicolored bangs. Apparently it runs in her family - flashbacks show that her father and brother had them as well.
- Childhood Friend: She and Keita used to play together as children.
- Cleavage Window: Some of her outfits fit this trope.
- Defrosting Ice Queen: It takes a while, but being around Keita gradually brings Hinoki out of her depression.
- Face Palm: Sometimes does this during Keita's Epic Fail moments.
- Faux Action Girl: Hinoki gets torched at, almost eaten by worms, attacked by out of control machines, chased by a bipedal elephant type monsters, and survives most of the show's enemies, before finally being turned into a Damsel in Distress near the end of the series. (Granted, she has no special abilities or training beyond being a Neuronoid pilot, so it's not like she was much of an Action Girl to begin with.)
- Form-Fitting Wardrobe: Pretty much◊ Hinoki's◊ entire◊wardrobe◊. The girl is seriously never seen in anything BUT this type of outfit.
- Go-Go Enslavement: In the final episodes of the series, Hinoki is tazed by Mamon and later wakes up in the Neuronoid wearing her dive suit, to be used as bait to draw Betterman out.
- Heroic Self-Deprecation: Even when she helps save the day, Hinoki still doesn't think too highly of herself. She constantly belittles her own intelligence, saying "I'm just an idiot." It turns out these were some of Mario's (affectionate) last words to her. He followed up these words with saying, "If you ever need me, I'll be there."
- Male Gaze: Hinoki◊ also◊ gets◊ this◊ a lot◊ from Keita.
- Long-Lost Relative: Why does Betterman look like her missing brother? Subverted, Lamia is not her brother, but has his memories and looks.
- Magic Skirt: Surprisingly enough, considering how short it is.
- Parental Abandonment: Her parents and her older brother Mario disappeared while exploring the Ajanta Caves in India. Their disappearance is the root of her emotional problems.
- Sexy Backless Outfit
- She's Got Legs: It's worth noting that she's the only female lead who isn't seen wearing an outfit that covers up to her knees.
- Tsundere: Can be this way to Keita at times. She ignores him at first, but only to avoid creating suspicion about their jobs. Though Keita upsets her, she doesn't take it out on him.
- Zettai Ryouiki: Her school uniform.
Shigeru AkamatsuThe passionate head of Akamatsu Industries, the company which is contracted by Mode Warp to operate the Neuronoids. Somewhat eccentric but a gifted inventor, he created a number of amazing gadgets. Became director of another GGG base and chief of new GGG through a buyout during its reorganisation post-FINAL.
Voiced by: Chafurin (JP), Dave Pettitt (EN)
- Casual Danger Dialog: Is considerably calmer than most while facing mind-blowing weirdness on a weekly basis.
- Cool Old Guy
- Gadgeteer Genius: Has created a number of inventive technologies. Some successful, others not so much:
- BFG: Subverted. Akamatsu can wield a massive device that looks like this, but it's really a high tech scanner.
- Cool Board: A rocket powered skateboard with an automatic jack to allow it to jump in the air!
- My Little Panzer: Literally. Akamatsu created a line of remote controlled miniature tanks that actually blew up after taking a direct hit. It was a commercial failure, since the "toy" could only be bought by licensed demolition experts.
- Psychic Block Defense: The "Barrier Boy" headbands, which are supposed to protect the user from Algernon. Later, the "Laser Head" headbands are developed to prevent full-on psychic attacks.
- Tricked-Out Shoes: Shoes with large springs under them, presumably used to help people jump higher.
- Last-Name Basis: Akamatsu is never called anything but Akamatsu or "Boss".
- Like Father, Like Son: He's Liger Shishioh's son, which helps explain his inventing.
- Married to the Job: His focus on the company had its personal cost such as estranging his wife from him.
- Mr. Exposition : Played with - When it's time to explain to Keita how the Neuronoid operates, Akamatsu is too busy to do so. So he hands the job to Li-chan.
- One of the Kids: Akamatsu shares the same tastes and interest as Keita.Akamatsu: "Never underestimate the cunning of a full grown boy."
- Papa Wolf: Cares a great deal for those working under him. Especially Sakura, who is revealed to be his daughter in the final episode.
- Renaissance Man: Capable of designing a large number of inventions (from toys to military weapons), as well run his own company.
SakuraA cryptic 15 year old girl linked to the "Limpid Channel", allowing her to read the minds of beings around her, and to pick up important information. Also a Dual-kind, she can pilot Neuronoids in a pinch. Unfortunately, due to her poor health she spends much of her time confined to a medical device called the Manage Machine. At the end of the series, it's revealed she is Akamatsu's daughter. He agreed to work with Mode Warp so he could use the Manage Machine for her.
Voiced by: Junko Iwao (JP), Mariette Sluyter (EN)
- Attention Deficit... Ooh, Shiny!: She has ADHD, and requires heavy medication and biofeedback pulses.
- Blessed with Suck: The Limpid Channel basically makes it impossible for her to live without Manage Machine treatment on a daily basis. (And that's in addition to really bad ADHD and a frail constitution.)
- Cool Chair: The Manage Machine. The thing looks like a cyberpunk throne, and has a pair of goggles for some reason (probably to keep visual stimuli to a minimum). It is used to keep her mental state in check, against the stress of a 24/7 connection to the Limpid Channel.
- Creepy Child: She's fifteen, but she's still damn good at pulling this off when the plot calls for it. Her monologues and speeches in the episodes and episode preview doesn't make this any less chilling.
- Ill Girl: Sakura was born with a weak constitution, and she hasn't gotten much better over time. Though she's a Dual Kind - and an extremely useful one, with her Limpid Channel - she's only used as a Head Diver in emergencies. It's pretty much the bane of her existence, to the point that she suggests Keita will survive solely because she wants the company of someone else her age (and not because she has any reason whatsoever to believe that he will actually survive).
- Disability Immunity: Either due to her condition, powers, or that's she's pumped full of meds, Sakura is the only one unaffected by Prof. Umezaki's pheromone attack.
- Improbable Hairstyle: Her twintails appear to be growing out of a single central point at the top of her head. (As her hair looks normal when she lets it down, it's probably done up using the same tech as Mikoto.)
- Missing Mom: Her mother walked out after becoming fed up with Akamatsu being Married to the Job.
- Naked First Impression: During her introductory scene in the pilot episode, Sakura is wearing a semi-transparent green gown. She wears this whenever she has to sit in the Manage Machine.
- Nightmare Fuel Station Attendant: Particularly in the next episode introductions, but occasionally during episodes as well.
- Psychic Radar: Her access to the Limpid Channel allows her to play this role - with it, she's capable of detecting if someone's in trouble, providing information on Betterman, and allowing Betterman to know when it's time to act. Her advice does tend to be either simple and direct ("it's coming!"), or specific yet so utterly disconnected from context as to be useless.
- Rapunzel Hair: Has a full head of hair despite her physical issues.
- Mega Twintails: The specific nature of her hairstyle, in this particular setting, might make it more likely than most examples.
- Waif Prophet: Near as we can tell, though, her physical frailness and Limpid Channel ability are unrelated. And while her predictions tend to be vague, she can filter them out well enough to provide consistently useful information (thus averting Cassandra Truth).
- You Gotta Have Pink Hair: True to her namesake. However, she subverts both Rose-Haired Sweetie and Cherry Blossom Girl due to being introverted and sickly.

- Adventurer Outfit: Asami dons Safari Apparel during the India expedition. It contrasts with the rest of the team, most of which just dress casually or wear Akamatsu uniforms.
- Cute Clumsy Girl: Downplayed - Asami is pretty competent. But she does end up slipping at times... often on Keita's face.
- Determinator: In regards to finding a cure for the Algernon virus.Asami: "I will never give up. Even if I were to be the last person left alive."
- Hot Scientist: Keita sure as hell thinks so!
- Ms. Exposition: Provides scientific and historical background to the gang when needed.
- Not So Above It All: Miyako seems like the last person to make any mistakes, crack a joke, or have any fun. But we do see instances in which these do happen. When a picture of a Christmas Party is shown, a jolly-looking Asami is wearing a goofy fake mustache and red nose.
- Shy Blue-Haired Girl: On par for the course.
- The Spock: The most calm and logical person in the group. If she does show any fear or anger, there's typically a good reason why.
- Technobabble: She provides a good percentage of this throughout the series.
- Unwitting Pawn: In the final episode it's revealed that she is in fact a carrier of the Algernon virus, due to being part of the scientific team involved in Yakusugi's ill-fated Dive Inspection - the one that released Kankel into the world.

- Peek-a-Bangs: Sometimes.
- Perpetual Smiler: Downplayed. Kaede often has a smile on her face, but when things get serious or dangerous, her expression does change.
- Psychic Powers: Her ability to read electro-magnetic impulses. The Superhuman Federation takes a particular interest in her due to this.
- The Tease: While she's in a relationship with Shou, she enjoys flirting with Keita quite a bit. Mostly because she loves to watch his brain turn off.
Shou YanagiComposed and capable 24 year old co-pilot of the Tyran. He also possesses psychic capabilities, such as precognition. In a relationship with Kaede. Though often collected, Shou does suffer from trauma at times due to his feelings of guilt regarding the death of his younger brother, Kei.

- Last-Name Basis: The only person who ever calls Shou by his given name is Kaede.
- Psychic Powers: To a lesser extent than Sakura or Kaede, but useful at times such as hypnotizing insect swarms. These powers are also why he sees certain visions.

Cactus PrickleOriginal co-pilot of the Kakuseijin that worked with Hinoki. During the Bottom World investigation, he becomes infected with Algernon and abandons the Neuronoid. He dies shortly after.
- The Faceless: While many non-important characters' faces are forever covered in shadow, Cactus doesn't get a face for no readily apparent reason other than creepiness.
- We actually do get to see his face exactly once, in the last episode - he appears immediately after Prof. Umezaki when Officer is explaining what happened to those who were survived the Dive Inspection. For all his Engrish English, he's rather Mukokuseki...
- First-Episode Spoiler: He dies. And then he gets mentioned several times afterwards such as being pals with Heichin.
- Posthumous Character: Makes an appearance in another episode during a dream sequence.

Mysterious species that appears during the course of the series. Throughout history, there have been sightings of the so-called "Betterman". They are capable of transforming from one form into another by consuming the seeds of the Animus Flower. Along with the ability to metamorphosis, they have access to the Limpid Channel.
- Telepathy: All Bettermen communicate this way.
- Our Vampires Are Different: Potentially immortal, capable of transformation, flight, and with incredibly strong forms , and they technically feed on people. This aspect is even lampshaded in the show, when a student talks about Vampires being able to take the form of a fog. Betterman Nebula's supersonic attacks create fog.
- Super Mode: Their combat forms.
LamiaThe titular Betterman of the series, saving the protagonists on several occasions. He is capable of eating the seeds of the Animus flower to transform into much more powerful fighting forms. Mysterious and vigilant, Lamia's default form is that of a humanoid male, with long hair. He also bears more than a passing resemblance to Hinoki's brother, Mario.

- Cool Shades: When in humanoid form. He also must have a secret stash of them, as he keeps tossing his shades every transformation.
- Hair Color Spoiler: He shares the same tri-colored shock as Hinoki. Is it her brother? No - Lamia only looks that way because he ate the Animus seed that sprouted from Mario. In the process, Lamia gained his memories, as well as some of his phsyical attributes.

- Ominous Fog: Nebula can also generate these with ultrasonic waves. Asami hypothesizes that this is as one reason why eyewitness accounts of Betterman is so rare.
- Power Crystal: Has one on his chest, which he uses to unleash "pectofolex" - light which can heal allies or hinder enemies.
- Swiss Army Hero: If he needs to fight, he can take on several forms:
- Jack-of-All-Stats: Nebula, capable of flight and the common battle form.
- Lightning Bruiser: Aqua, faster than even Nebula (going over 1000 km. per hour) and at least as destructive. The only downside is that it can only be used in the ocean.
