- My Greatest Failure: The deaths of the Beams had a particular effect on him, making him very guilt-ridden for unintentionally leading them to invade the Gekko and not doing anything to prevent their deaths.
- Naďve Newcomer: Renton starts out as one when he joins the Gekkostate. He's a jovial kid who hates his dull life and wishes to have more freedom. Too bad Gekkostate sees him as a gawky, timid, 14-year old snot nose whose sole purpose is to be their Butt Monkey. Renton is enraged that the crew sees him as an immature baby whom they give no respect. Come several episodes later, he's had enough, blows his stack in a firefight, and slaughters a whole KLF squadron very horrifically. Shortly afterward, Eureka's pissed at the whole crew for egging him all this time, which causes them to drop all ideas of messing with him and treat him as an equal.

- Ace Pilot: One of the many things he's famous for.
- Action Dad: In a Team Dad sense for Gekkostate and in a literal sense when Talho is pregnant with their child.
- Adaptational Heroism: He is a lot less of a Jerkass and much more laid back in the manga. He only hit Renton once, and he arguably deserved it at the time.
- Aloof Big Brother: Acts as this towards Renton.
- Bad Dreams: In one episode, he has a nightmare of the atrocities he committed while part of the SOF.
- Badass In Charge: The leader of Gekkostate who is an Ace Pilot, former military, and has Nerves of Steel.

- Bishounen: Mild case of this, despite his Perma Stubble. Perma Stubble which is all the more hilarious cause he's shown shaving in one episode.
- Broken Ace: Previously the ace of the SOF, and definitely broken, after everything he went through and did.
- Broken Pedestal: Mild case of this for Renton, who found Holland's image was somewhat more inflated than justified, even admitted by the man himself. Eventually he becomes worthy of that hype through character development.
- The Cameo: He makes a brief appearance in Gravity Boys & Lifting Girl to compliment Sumner on his lifting.
- Cain and Abel: The Abel to Dewey's Cain.
- Character Development: By seasons 3 and 4, he becomes more mature and caring, due to him learning that he needs to face his problems rather than run away from them if he wants to help save the world and gain the trust and respect of others. He becomes very protective of the crew, particularly Renton and Eureka, to the point where he seems to favor them for important activities. When Talho tells him that she is pregnant with his child, he starts to take on a surrogate father role to the crew and he becomes more open and friendly with them.

- Familial Reveal: His last name is Novak; he's the younger brother of Dewey Novak.
- Fatal Flaw: A recurring theme in the middle portion of the series with Holland is his instinct to run away from his past and responsibility, using Eureka, Renton (in this case, physically and emotionally abusing him), and lifting as a way to escape, much to Talho's chagrin. Hell, it almost became a literal one when it almost lead Gekkostate straight into a State army trap until Renton and Eureka's action and reunion saved the team. Character Development helps get rid of this trait.
- A Father to His Men: Takes a while, but he grows into this over the course of the series.
- Freudian Excuse: It was Dewey's efforts to destroy the Scub Coral, and potentially the world, that caused Holland to personally set out to stop him by thinking he can partner with Eureka and unite the humans and Scub Coral to overthrow Dewey. Because of this, Dewey is indirectly responsible for Holland's initial indifference towards the crew, his obsession with Eureka, and grudge towards Renton in the beginning.
- Good Is Not Nice: Holland is on the side of good for sure. However, he spends the first half of the series being a jerk to his crew (save Eureka and Talho), even being physically and emotionally abusive to Renton. Thankfully, he gets over it.
- Green-Eyed Monster: Arguably the reason for some of his worst Jerk Ass moments. Once he gets over it, he is a much nicer guy.
- Heartbroken Badass: He had a messy first relationship, which is one of many issues that led to the mess he is today.
- Hero of Another Story: While not seen, his defection from the military in the video games (taking place a few years before the anime) has a fair amount of background importance. That said, Holland's story is already shown in the anime, aka the original adaptation; that is, as a hero in the main storyline, Holland's the Hero of Another Story in the spin-off.
- Jerkass: At his worst moments, especially in the first half of the series.

- The Leader: Of Gekkostate.
- Living Legend: By far and away one of the most famous people in the entire world.
- Man Child: Deconstructed. Holland's immature nature has him poorly handling his anger (i.e., emotionally and physically abusing Renton) and straining his relationships with Renton, Talho, and the rest of Gekkostate.
- The Masochism Tango: With Talho. They eventually work things out.
- Papa Wolf: Turns more and more into this for Eureka as the series goes on. See Episode 38 for a particularly good example.

- In seasons 3 and 4, Holland adopts a somewhat secondary father figure to Renton and now treats him like a son.
- The Resenter: Towards Renton initially.
- Screaming Warrior: Likes to scream while charging into the fray.
- Sergeant Rock: Sure, Holland might be a MAJOR asshole at times, but he's respected and even liked by the Gekkostate crew because he's competent, wouldn't have them do something he wouldn't do himself, and despite his outward Jerkass (especially in the first half of the series), is rather concerned for their welfare.

- Smoking Is Cool: In the manga and novels, he is a smoker, unlike his anime counterpart.
- Supporting Leader
- Team Dad: Stern, determined, calls the shots.
- Took a Level in Kindness: In the anime, this is a major part of his Character Development. He goes from a Jerkass Man Child to a mature, father-like figure to Renton.

- Green-Eyed Monster: Due to Holland's dedication to protect Eureka and put her safety above everything in hope of becoming her partner, Talho exhibited great jealousy and resentment towards Eureka, and lashed out in anger towards Holland for not only not taking her own feelings for him into consideration but using Eureka as an excuse to run away from his problems. She also tended to get angry at him when he showed his obsession and affection for his first love, Diane.

- Important Haircut: Talho trims her normally unkempt hair as part of her complete outer (and inner) makeover in episode 30.

- The Masochism Tango: With Holland. They eventually work things out.
- Morality Pet: Besides Eureka, Talho is the only one that Holland doesn't take his anger out on.
- Ms. Fanservice
- Number Two: Talho is the second-in-command of Gekkostate.

- Stripperiffic: Until midway through the series, at which point she ditches the look for a very covering bodysuit.
- Tareme Eyes: Representing her motherly personality.
- Team Mom: She softens Holland's harsher tendencies and keeps everyone in line. Bonus points for being pregnant with the Team Dad's child.
- Took a Level in Kindness: Starts in episode 30. She loses her immature, temperamental nature. Thus, she becomes more nicer to Renton and Eureka.
- Tsundere: Towards Holland. Due to his anger and immaturity, she tended to lash out in anger towards him and questioned the length of his true feelings towards her.
- Used to Be a Sweet Kid: An older example. Prior to joining the Gekkostate, she was well-liked for her maturity and kindness towards others. However, upon joining the Gekkostate, she made major changes in her personality and appearance: Dressing in a Stripperiffic fashion and having a Woman Child attitude.
Photographer and main editor of Ray=out. He was also a former member of the military and defected with Holland.
- Actual Pacifist: Only takes photographs, never fights.

- Non-Action Guy: Despite allegedly being ex-military, he never participates in a single battle throughout the series (and never tries to).
Maurice, Maeter, and Linck
Eureka's adopted children, who she took care of after she killed their parents during a military raid. They are fiercely protective of their "Mama" and like to play pranks on Renton, but warm up to him over time.
Maeter is voiced by: Eriko Kigawa (JP), Peggy O'Neil (EN)
- Attention Whore: All of them compete with everyone else for Eureka's attention and affection.
- The Baby of the Bunch: Linck is the youngest of them, and also the youngest of member of Gekkostate.
- Bratty Half-Pint: Maurice is the most sensible (probably due to being oldest) while Linck is the most immature.
- Cheerful Child: All of them, but Maeter and Linck moreso — when they're not being mean to Renton or crying, that is.
- Crazy Jealous Guy: Maurice becomes this to Eureka as a result of developing something of an Oedipus Complex. It starts off with Maurice pranking Renton with his siblings and went Up to Eleven in episode 45 when he pulls a gun on Renton thinking that Eureka loves Renton more than him. Eureka talks him out of it though and he accepts Renton as his father.
- Dark and Troubled Past: Their biological families were killed by Eureka, their adoptive mother.
- Does Not Like Shoes: Linck is the only one of his siblings (an perhaps the only one of Gekkostate) to not wear shoes.
- Expy: They resemble the three little kids from the original Mobile Suit Gundam quite a lot.
- Freudian Excuse: Their initial dislike of Renton was because they feared he would take away Eureka. The "excuse" comes in the fact that their original families died when they were very young.
- Happily Adopted: By Eureka, and later by Renton as well.
- Hidden Depths: Maurice has an interest in books and photography, which Stoner introduced him to.
- Interspecies Adoption: Since Eureka is a Coralian.
- The Load: Justified. None of them do anything remotely important for Gekkostate because they are children. They only serve to be the reason behind Eureka's Heel–Face Turn.
- Morality Pet: To Eureka. Finding them triggered her Heel–Face Turn.
- My New Gift Is Lame: Eureka tends to get them textbooks as presents (usually ones that are too advanced for them). She does put thought into it, she just has no idea what they might like. And they need an education, after all.
- Named After Somebody Famous: The kids are named after Nobel Prize-winning Belgian writer Maurice Maeterlinck.
- Oedipus Complex: While Maeter and Linck still acted like a son and daughter to Eureka, Maurice started to develop this overtime. It started with him blushing and avoiding her to her confusion, but then he turned into a Crazy Jealous Guy whenever Renton was with her.
- Parent with New Paramour: They don't approve their "mama"'s relationship with Renton, usually get in the way of Renton towards Eureka' heart and are afraid that Eureka chooses him over them. They eventually accept him as their adoptive dad.
- Spoiled Brat: Being inexperienced as a mother, Eureka has a tendency to spoil them.
- Tagalong Kids: Especially egregious in the finale.
- Took a Level in Kindness: They all go from disrespecting and harassing Renton to calling him "papa" and believing that he will save Eureka.
- Troubling Unchildlike Behavior: Maurice. No normal kid would pull a gun on his mother figure's boyfriend just because he wants his mama all to himself.
- Turn the Other Cheek: Maurice knows Eureka is the one who killed his real mother, but he doesn't hold any grudge against her and loves her as his adoptive mother.
- Youthful Freckles: Maeter is the only one to have them and, like her siblings, she's energetic.

An enigmatic old man who always hangs around the Gekko.
Voiced by: Takkou Ishimori (JP), Tony Oliver (EN)

Second-in-command of the Gekkostate crew. One of the few people Holland confides his troubles to.
Voiced by: Taro Yamaguchi (JP), Tony Oliver (EN)
- Beware the Nice Ones: In the manga, at least, when the Gekko is invaded by assassins after Eureka, he very calmly shoots one in the head, making him one of the only characters with an onscreen kill.
- Childhood Friends: He and Holland have been buds since they were three.
- Eyes Always Shut
- Good Scars, Evil Scars: Has a barely noticeable scar that divides his left eyebrow.
- Nice Guy: Is easily one of the friendliest of the adult males on the crew.
One of the more ordinary members of Gekkostate. Has a crush on Moondoggie.
Voiced by: Fumie Mizusaka (JP), Jessica Straus (EN)
- Ambiguously Brown: Gidget has a tanned skin tone and it's unknown if it's just a sun tan or not.
- Bare Your Midriff: Her shirt shows off her stomach area.
- Beta Couple: With Moondoggie. They have the least amount of drama as a couple.
- Cool Big Sister: Though even less so than Hilda, due to being much younger.
- The Ditz: She's not very bright.
- Heterosexual Life-Partner: Jealous of Talho and Hilda being this, she wants this kind of relationship with Eureka as the only other teenage girl in Gekkostate.
- Nice Hat: A pink and white hat with a purple visor.
- Weakness Turns Her On: In regards to Moondoggie, she mentions that looking at him makes her want to "scoop him up and help him along."
The newest member of Gekkostate before Renton. Jealous of Renton, despite being viewed as a big brother figure by him.
- Affectionate Nickname: Dubbed "Brother Doggie" by Renton, much to Moondoggie's annoyance.
- Ascended Extra: He gets to be a tritagonist in the video games.
- Beta Couple: With Gidget. They have the least amount of drama as a couple.
- Bishōnen: He's drawn prettier than the other men of Gekkostate, and Gidget mentions his pretty face at one point.
- Bromantic Foil: To Sumner in New Vision, being loud and childish next to Sumner's Only Sane Man status.
- Butt Monkey: In an unusual take on the trope, he was the ship's official Butt Monkey before Renton arrived, and actually resents Renton from taking the position from him. Of course, as Renton grows as a character, Moondoogie reclaims his role as the Butt Monkey.
- Cool Big Bro: To Renton, who sees him as a surrogate big brother.
- A Friend in Need: In New Vision, where he sticks by Sumner, in spite of all their bickering and not necessarily knowing what's going on or agreeing with what they're doing.
- Hidden Depths: He turns out to be a pretty good ship pilot.
- I Just Want to Be Badass: As the series goes on, his usefulness declines, which he's painfully aware of. Luckily for him, he gets promoted to the Gekko's pilot.
- Instant Expert: New Vision suggests that he's a (ship) piloting prodigy.
- Jerk with a Heart of Gold: Not as bad as Holland, but unsurprising for a teenage male, he's prone to grumpiness and being egocentric. At the end of the day, though, he's still a good guy.
- Meaningful Name:
- According to one of the definitions given by Urban Dictionary, a moondoggie is 1960s slang for a habitual marijuana user. Almost certainly deliberate given the series' large amounts of references to 60s counterculture (and the presence of a character named Stoner).
- It's also a reference to the character in the Gidget franchise, just as the character's real name (see Only Known by Their Nickname below) is a reference to James Darren, the actor who played Moondoggie in the three original films.
- Nice Hat: A blue hat with a couple of white markings.
- Only Known by Their Nickname: According to his license, his name is actually James Darren Emerson. Nobody ever calls him this.
- The Resenter: He's initially not very fond of Renton due to his jealousy over him.
- Screw This, I'm Outta Here!: At some point pre-series, as seen in the video games, he temporarily left the Gekkostate (implied to be because of being treated like the Butt Monkey, if you assume the "friends" he was complaining about to Ruri were the Gekkostate). At the end of New Vision, he returns and is welcomed back.
- Took a Level in Badass: Eventually becomes the pilot of the Gekko.
- Vitriolic Best Buds: With Sumner in the video games. Them constantly bickering didn't stop Moondoggie from giving Sumner his truck or from remaining in the conflict largely to stand by Sumner.
United Federation Force
The main antagonist. Once a disgraced military official following Holland's defection, he ultimately seizes control over the United Federation Forces so he can lead a crusade to destroy the Coralians at all costs.

- Ambition Is Evil
- Authority Equals Ass Kicking
- Badass Cape
- Big Bad: The main antagonist of the series who is trying to kill the Coralians.

- The Chessmaster: In a complicated and carefully calculated plan, he undermines the public's faith in the Sage Council and overthrows them.
- Colonel Badass
- Dark Messiah: Becomes one, when the Ritual of the King becomes laid out to us.
- Familial Reveal: He is Holland's older brother.
- Faux Affably Evil: While he can be charming and seductive in order to get what he wants, he is ultimately revealed to be a psychotic megalomaniac driven solely by his hatred for the Scub Coral and his brother, Holland.
- Impoverished Patrician: According to the lifestory he recounts to Anemone, he's allegedly descended from a noble family responsible for leading humanity's exodus from Earth. After Dewey murders his father in order to become the family's new patriarch, the Novak family is deprived of its legitimacy and he and Holland are forced into poverty.
- It's All About Me: While he claims to be acting in the interests of mankind, it is ultimately revealed that he cares about nothing but satisfying his hunger for vengeance against a world which he perceives has wronged him since his childhood.
- Knight Templar: He sincerely believes in his cause, and he's all the more nasty because of it. Subverted towards the end of the series when you find out his idea of "saving" the world means destroying it.
- Lack of Empathy: Despite being prone to melancholy bouts of self-pity over an unhappy childhood (much of it do to his own making), he has no regard for the well-being of those around him and is downright contemptuous of displays of compassion. When Dominic objects to how he repeatedly refers to Anemone as a "thing", he laughs derisively at his subordinate's concern before coldly dismissing him.
- Light Is Not Good: He wears an all white uniform and is the Big Bad of the series.
- Manipulative Bastard: How he preys off of Anemone's abandonment issues in Episode 36 is downright creepy. "My sweet little Anemone..."

- Never My Fault: Blames Holland for the succession ritual failing when he caused it in the first place.

- Parental Substitute: In the manga, it's implied he was one for Dominic.
- Pet the Dog: In the manga, he thinks back to fond memories of the times he and Holland spent together as children before his death (may count as both a Crowning Moment Of Heart Warming, Tear Jerker, and Alas, Poor Villain all at the same time). In the anime, he is depicted as a thoroughly egocentric and coldhearted individual with no humanizing moments aside from a brief flashback to his childhood where he is seen visibly grief-stricken over the death of his mother.
- Self-Made Orphan: Dewey kills his and Holland's father in an attempt to perform the "Sacrificial King" ritual
- The Unfettered: There is nothing he will not do in pursuit of his goal.

Pilot of the Federation LFO, Nirvash typeTheEND. Prone to violent mood swings that can only be controlled through the use of sedatives, she refuses to listen to anyone other than Dewey. Owns a strange badger-like pet named Gulliver.
- Ace Pilot: She's a great pilot who prefers to ambush her opponents and rain blow after blow upon them. However, she's only that way because she uses a Psycho Serum before she pilots.
- Adaptational Heroism: In the manga. She's a lot nicer, especially toward Eureka. And Dominic at the end.
- Anger Born of Worry: When she goes to save Dominic after she accidentally attacks him with her mech while he's falling from the sky, clinging to a ref board to try and save her. She admonishes him for doing something so reckless, even though they're both in a freefall at this point. Now she's normally been pretty harsh on poor Dominic until now, but fortunately for him, she lets it slide. Cue Big Damn Kiss.
- Anti-Villain: As we discover more of her true personality and tragic past.
- Ax-Crazy: When she takes the serum, Anemone becomes viciously determined to kill her enemy with, even with overkill.
- Badass Adorable: A cute young lady with pink hair? Check. Can pilot theEnd like a pro? Double check.
- Belated Love Epiphany: She realizes she is in love with Dominic around the time of his Heel–Face Turn when she thinks he has abandoned her, which leads to a far more serious Despair Event Horizon for her.
- Beneath the Mask: Her Daddy's Little Villain attitude is revealed to be a facade.
- Blood Knight: She loves violence, at least when she is on her Psycho Serum.

- Childhood Friend Romance: With Dominic in the manga.
- Crazy Consumption: Mmmmm, strawberry jam.

- Dark Action Girl: A psycho Ace Pilot who also doubles as the Evil Counterpart to the The Heroine. Thankfully, she pulls a Heel–Face Turn.
- Dark and Troubled Past: Her family was murdered when she was a child and later was diagnosed with Desperation Disease. She was then subject to horrible experiments to become Coralian-like.
- Dark Magical Girl: Shows more traits of this as the series goes on. She's an Anti-Villain and the heroine's Evil Counterpart who seeks to please the Big Bad and is terrified of being abandoned and finally makes a Heel–Face Turn thanks to The Power of Love.
- Defrosting Ice Queen: Towards Dominic by the end.
- Devoted to You: Her bitchy and psycho personality and constant abuse doesn't affect Dominic's devotion to her at all. He will always protect her no matter what.
- Domestic Abuser: She's got it in for poor Dominic for most of the series.
- Emotionless Girl: Was apparently this before the start of the series, as Dominic and Dewey note that she has a personality now. She does have Desperation Disease, after all.
- Evil Counterpart: To Eureka. Both are the Ace Pilot of their organization and have a Love Epiphany when their love interest vanishes. They each even have their own Morality Pet (the kids for Eureka, Gulliver for Anemone). However, Anemone is with the United Federation, while Eureka is a member of Gekkostate. They also contrast in color scheme: Anemone is red (violent and emotional) and Eureka is blue (reserved and calm). Subverted in the end. She became the way she was because of the constant inhuman expreiments forced on her by Dewey, who she really hates. That and her Heel–Face Turn at the end shows she never was "evil".

- Exotic Eye Designs: Her purple eyes each have a single straight line etched across them.

- I Just Want to Be Loved: Besides wanting to have a normal life, Anemone also wants to find someone to love and who will also truly love her.

- Light Feminine and Dark Feminine: The dark to Eureka's light.

- Psychic Nosebleed: In this case, used as an indicator of the abuse her job puts on her mind and body rather than actual Psychic Powers.

- Red Oni, Blue Oni: The red (loud, emotional, and violent) to Eureka's blue (quiet, reserved, and calm).
- Reverse Grip: TheEND's swords.
- Rose-Haired Sweetie: Inverted. It's pink-haired, orange-themed Anemone that's the near-crazy Anti-Villain to Eureka's blue-themed heroine. Played straight by the end, when she's freed from Dewey's influence and reforms.
- Sanity Strengthening: She starts off as a violently psychotic Tyke Bomb, but grows much stabler in the presence of her handler/guardian Dominic. Late in the series, he manages to restore her sanity completely through The Power of Love.

- You Have Failed Me: She is terrified of being replaced for failing too much.
An elite officer in the U.F. Force and Dewey's confidant. He also has the unenviable job of looking after Anemone who, despite being on the receiving end of a very abusive relationship with her, he is actually fond of.
Voiced by: Shigenori Yamazaki (JP), Peter Doyle (EN)

- Determinator: Did we mention yet that he shrugged off laser burns to save Anemone in the manga? Not to mention his Shut Up, Hannibal! moment before that, or afterwards when he puts up with the pain—if not putting himself in more pain—to get him and Anemone out of there.
- Dogged Nice Guy: To Anemone. His perseverance ultimately pays off.
- Dude, Where's My Respect?: There are men in the military far older than him and yet of much lower rank, who often have trouble obeying his orders. Dominic is also aware that commanding officers give him a hard time following his orders for Dewey as they think he's still a kid.
- Easily Forgiven: The Gekkostate crew decides to trust him implicitly as soon as he shows similarities to Renton, especially his commitment to the one he loves.
- Enemy Mine: He and Renton are forced to work together to save Eureka and Anemone.
- Even Evil Has Loved Ones: "Evil" is a little much for him, but he does has someone he cares about: Anemone. He's as equally devoted and in love with her as Renton is to Eureka.
- Even Evil Has Standards: Calling him evil is a bit of a stretch, but he will NOT stand for inhumane experiments performed on young women to make them into pilots for TheEND. ESPECIALLY if Anemone already suffered through such a treatment herself.
- Evil Counterpart: To Renton. Both are relatively new members to an organization, and are given little respect by the other members. The only person of the organization they have a close connection with is an Ace Pilot girl they quickly become devoted to. Both of them are Wide-Eyed Idealist and go through a Broken Pedestal moment with their organization's leader. However, while Renton is with Gekkostate, Dominic is with the Federation. Subverted since Dominic was never truly "evil" and made a Heel–Face Turn near the end.
- Freudian Excuse: As a result of having been orphaned at a young age and seen the effects of a war, Dominic becomes stoic and blunt towards others, and takes his duty as a soldier seriously.
- Friendly Enemy: He considers Renton (who is a member of the Federation's enemy) as a friend.
- Heel–Face Turn: Near the end of the series, he abandons U.F. Force and joins Gekkostate's side.
- Heel Realization:
- In the anime, Dominic realizes how sadistic his organization is when he sees girls, just like Anemone, undergo brutal, and ultimately fatal, experimentation in the lab. Cue the Vomit Discretion Shot and his Heel–Face Turn.
- In the manga, this occurs when Ruri informs him of Dewey's true motives, with Dominic realizing that everything he's fought for up until now was a lie.
- Heroic BSOD: Coinciding with his Heel Realization above, though it doesn't last for long.
- Heroic Sacrifice: In the manga, via You Shall Not Pass fashion, as he shields Renton from a hoard of Coralians.
- Impaled with Extreme Prejudice: In the manga.
- Improbable Hairstyle: The back part of his hair stands up on its own.
- Innocently Insensitive: When Dominic gives Anemone a couple of anemones as a present, she asks if he's mocking her — he didn't realize that anemones mean "disappearing hope."
- Interspecies Romance: He (human) and Anemone (artificial Humanoid Coralian).
- Living Emotional Crutch: To Anemome. She finally realizes it after he seemingly abandons her and she hits the Despair Event Horizon.
- Love Martyr: His endurance of Anemone's condescending manner and physical assault is legendary.
- Meaningful Name: Originally from the late Roman-Italic name "Dominicus" its translation means "Of Our Lord", "Lordly", "Belonging to God" or "of the Master". This fits with him being the servant of Dewey and Anemone, both who outrank him.
- Mistress and Servant Boy: His relationship with Anemone.
- Muscles Are Meaningless: Dominic was able to easily strong arm a more physically buff man.
- My Country, Right or Wrong: Deconstructed. Dominic is loyal to Dewey's cause, but comes to be greatly disturbed by his amoral actions and disregard to Anemone's mental well-being.
- Nice Guy: Develops into one Post-Heel–Face Turn; he's now a humble, polite, respectful man to those he initially considered beneath him.
- No Sense of Direction: You know you're bad when Renton calls you out on it.Dominic: Is "west" the direction of the hand you hold a fork with?
- Not So Different: To Renton, who is also devoted to protecting the girl he loves.
- Official Couple: With Anemone.
- Only Friend: He is the closest to Anemone (sans Gulliver) and he genuinely cares about her.
- Orphan's Ordeal: As revealed in Episode 44. It helps to explain why he's so devoted to Anemone - hers is the closest connection he has with another person.
- Punch Clock Villain: He may work for the United Federation, but he's only doing his job.
- Shut Up, Hannibal!: In response to a hallucinated skeletal Dewey trying to Break Them by Talking, in the manga.
- Single-Target Sexuality: Dominic has no interest in other girls, except one: Anemone.
- Stronger Than They Look: You don't realize it until you see him twist the arms of thugs twice his size without any visible effort, as well as his ability to shoulder Anemone's improbably heavy Gulliver without extreme strain. There's also the stuff he does while saving Anemone in the manga, like shrugging off laser burns.
- Subordinate Excuse: While Anemone doesn't outrank him, it should be clear that he chose this position for something more than a good paycheck.
- Sugar and Ice Personality: He can be cold at times, mainly when on the job, but he's a pretty nice guy otherwise.
- Teeth-Clenched Teamwork: With Jurgens, pre-Heel–Face Turn.
- To Be Lawful or Good: Once it's clear that this divide exists to begin with, he easily chooses 'good,' even telling Jurgens that there isn't even a choice.
- Token Good Teammate: Between Dewey, Anemone, and the Ageha squad children, he's about the only one who's actually trying to do the morally right thing.
- Took a Level in Kindness: From Ep. 45 and onwards, as signified by his newfound friendship with Jurgens and Gulliver, neither of whom he got along with before due to his previous uptight behaviour.
- Vomit Indiscretion Shot: In Episodes 43 and 44.
- Wide-Eyed Idealist: A bit subtler than most, but still very naive about how the world and human relationships work.
- You Gotta Have Blue Hair: Dominic has greenish-black hair.
Voiced by: NoneAnemone's pet badger.
- Fat Cat: A badger variant. It is immensely overweight, and therefore can not be easily transported or moved.
- Morality Pet: To Anemone.
- Shipper on Deck: For Dominic/Anemone. He puts their hands together as they are all falling from the sky.
- Team Pet: For the Federation, but specifically towards Dominic and Anemone.
- Trademark Favorite Food: Like Anemone, Gulliver appears to really like jam.
The Ageha Squad
A group of specially-trained children who answer directly to Dewey.
- Because You Were Nice to Me: They admire Dewey and follow his orders because of this.
- Cute and Psycho: The sage Coda notes they're beautiful children. This is right before one of them shoots a maid in the head with no hesitation.
- Enfant Terrible: Despite their young age, they're some of the most psychotic characters around in the series.
- Evil Counterpart: To Anemone. They all work under Dewey and are Cute and Psycho. However, Anemone isn't truly "evil" and actually despises Dewey; the Ageha Squad are shown to be more cold-hearted than Anemone and truly admire Dewey.
- Freudian Excuse: They were victims of an ethnic cleansing. Apparently Dewey was the first one to show them kindness.
- No Name Given: Their names are never revealed.
- Shadow Archetype: To Anemone. They represent what she could've become had she actually cared for Dewey.
- Troubling Unchildlike Behavior: They show no qualms with murder and gleefully follow Dewey's messed up orders.
- Tykebomb: Raised by Dewey to help him with his nefarious plans.
Captain of the Federation flagship Izumo.

- Badass Mustache
- Big Brother Mentor: Mild version to Dominic.
- Colonel Badass: His rank equates to this. Besides, being willing to take on an entire enemy armada in one ship takes some balls!
- Dark and Troubled Past: His wife and daughter were killed in a battle at Warsaw.
- Defector from Decadence: Sides with Gekkostate after witnessing the inhuman experiments done to make artificial humanoid Coralians.
- Demoted to Extra: While a minor character to begin with, he only appears once in the manga and then never again, with the role of facilitating Dominic's Heel–Face Turn going to Ruri instead.
- Even Evil Has Standards: He draws the line at horrible experiments and deliberately harming innocent people.
- A Father to His Men
- Heel–Face Turn
- Its Pronounced Tropay: His name is pronounced YOOR-gens.
- Punch Clock Villain
- Reasonable Authority Figure: For starters, he reads Ray=out and actually takes it seriously when the heroes reveal information in it.
- Shipper on Deck: He's all for Dominic/Anemone.
- Teeth-Clenched Teamwork: With Dominic at first.
- To Be Lawful or Good: He chooses good.
- You Shall Not Pass: Tries to pull this off in Episode 49 with his crew.
New Wave and New Vision Characters
The male protagonist of the video game prequels New Wave and New Vision. After graduating New Wave Academy, a school for future military recruits, he and most of his friends joined the Sawyer Team KLF group. His beliefs and love for Ruri convince him to rebel against the military at the end of the first game, and deliver a captured Nirvash to Holland and Eureka.In the second game, he, Ruri, and Moondoggie fight against the Azure group and corrupted members of the military, including some of Sumner's old friends, to prevent mass destruction.
- The Ace: Explicitly referred to as the ace of the Sawyer Team.
- Ace Pilot: The star of New Wave (and then the Sawyer Team), after Ruri leaves. Even years later, he hasn't lost his touch and ranks among the best.
- Adorkable: He can be endearingly flustered and/or enthusiastic. Less so in New Vision, having grown up a bit, but it's still there at times.
- Battle Couple: With Ruri in New Vision.
- Been There, Shaped History: He was the one who delivered the Nirvash to the Gekkostate.
- Black Sheep: Of the famous Sturgeon family, after he chose to quit officer academy and join New Wave, and then doubly so after he defected from the military.
- Broken Ace: Becomes this by New Vision. Compared to the Ace Pilot before who thought everything was new and shiny and amazing, the Legally Dead Retired Badass he's turned into admits that lifting is now just another way to keep himself fed, and he's beginning to forget how he used to feel back in the old days.
- Broken Pedestal: In Gravity Boys & Lifting Girl, his favourite brother Torino becomes this after Sumner witnesses him shooting (and killing) the brother of one of Sumner's friends.
- The Cameo: Sumner and Ruri make a brief appearance in the anime. He also appears in the manga's epilogue, in a panel alongside Ruri, Moondoggie, and Gidget.
- Desperately Looking for a Purpose in Life: His main goal, and part of why he keeps chasing after/sticking with Ruri despite her occasionally questionable treatment of him, as he hopes that being with her will help guide him.
- The Ditherer: His main problem: he doesn't really know what he wants to do.
- Everyone Went to School Together: He attended the same high school as Gillian and Steven. This being Sumner, he doesn't even remember them.
- Extreme Doormat: Starts off as one for his family in the Gravity Boys & Lifting Girl.
- Faking the Dead: Albeit not by choice. After defecting from the military, he's declared officially dead rather than a traitor so as to not shame the Sturgeon name, so he just rolls with it.
- Fanboy: It's somewhat of a Running Gag that he's an LFO fanboy, weirding some people out. He also idolizes B.B. as a teenager, with that respect showing itself even as an adult where he uses the same moniker in a lifting tournament once.
- Forgotten First Meeting: With... just about the entire cast barring Hooky. Shaun and Pez tried to mug him once (though they don't seem to remember him either), and he utterly fails to retain any info about Gillian and Steven's existences during the years they attend school together. And, of course, there's the entire mess with Ruri.
- Good Is Not Soft: He's a genuinely nice and compassionate guy, but when push comes to shove? He ends up killing a fair amount of former allies provided they tried to kill him first.
- Good-Looking Privates: One of the family servants notes how handsome he is in his military uniform.
- Grew a Spine: This is especially noticeable in the Japanese version, where he switches from boku to the more assertive ore by the end of New Wave.
- Heel–Face Turn: Mostly for Ruri, hence why he's somewhat bitter in New Vision, believing that she ditched him afterwards.
- I Have No Son: His family pulls this on him after the events of New Wave. You don't get much more disowned than being declared Legally Dead so that the family can save face.
- I Will Find You: His objective at the end of New Wave, after losing everything, is to find Ruri.
- Ignore the Fan Service: In Gravity Boys & Lifting Girl, he never seems to acknowledge that he knows a very attractive older woman whom his (more hormonal) friends immediately fall for. According to her, it's because of his Single-Target Sexuality for B.B.
- Innocently Insensitive: God, it's almost painful to see how oblivious he is around Gillian.
- Jade-Colored Glasses: A mild version in New Vision, in that he's still rather idealistic, but also a fair bit grumpier thanks to his experiences in New Wave.
- Jerkass Realization: He initially assumes his classmates are shallow jerks who only see him as a Sturgeon, before realizing that he was the shallow jerk for immediately dismissing them like that based on an ultimately false assumption.
- Legally Dead: After the events of New Wave. See Faking the Dead above.
- Lonely Rich Kid: Played with. At age fourteen, he's rich and he's mostly friendless, but it's somewhat self-imposed as he automatically assumes everyone only focuses on his family name. Once he realizes that he's wrong and lets himself become part of a social circle, he's much happier.
- Love at First Sight: He became infatuated with Ruri since the first time he saw her... not that he knows that it was her.
- Love Martyr: For Ruri, to an extent. Her being Troubled, but Cute doesn't do wonders for their relationship and Sumner knows it, but he's devoted to her all the same.
- Massive Numbered Siblings: He has five older brothers. It probably says something about his family that he doesn't seem to be close with any of them but Torino.
- Military Brat: However, rather than staying in officer academy like his father wanted, he joined New Wave.
- Nice Guy: In New Wave, compared to his Sugar and Ice Personality in Gravity Boys & Lifting Girl and the more beleaguered attitude he develops in New Vision.
- Not So Above It All: Claims he was never competing with Hooky—before insisting that he won that last 'tie', thank you very much.
- Oblivious to Love: To Gillian's.
- Only Sane Man: Between him, Ruri, and Moondoggie.Sumner: There are three of us here, but it doesn't matter. I'm still alone. I guess what I'm trying to say is why don't these two DO ANY OF THE WORK!?
- The Quiet One: Used to be this. It was part of what attracted Gillian to him.
- Retired Badass: The retirement was forced on him, what with being Legally Dead, but he amounts to this in the beginning of New Vision, with both Wes and Moondoggie bemoaning how all of his talent as an Ace Pilot is going to waste.
- Single-Target Sexuality: Without even realizing it! Utter lack of interest in anyone else aside, he was mildly obsessive over both B.B. and the girl he saw once by chance, as others note, but ends up with Ruri—except they're all the same person.
- Stepford Smiler: Develops into one in Gravity Boys & Lifting Girl upon realizing how empty his life is, having everything decided for him by his family.
- Sugar and Ice Personality: As a teenager, due to believing his classmates only saw him as a Sturgeon. Around others and once he realized that wasn't the case for everyone, he's significantly warmer.
- Underestimating Badassery: Frequent in the beginning of New Vision. Unlike some of the other Ace Pilots on this page, Sumner falls off the radar, so most people assume he's your run-of-the-mill punk who pilots an LFO... without realizing that he used to be one of the military's best.
- Vitriolic Best Buds: With Moondoggie. Sumner's clearly exasperated with him half the time, but is good friends with him nevertheless.
Sumner's love interest. In New Wave, she left New Wave Academy after learning about the military's insidious motives. Although her efforts to rebel lead her to aligning with black market dealers, she eventually reunites with Sumner long enough to help him realize what path he should follow.In New Vision, Ruri is able to meet Sumner again, and they (and Moondoggie) try to stop a military scheme that is driving their own pilots insane. After the conflict is over, she and Sumner remain together.Ruri also made an appearance in the manga adaptation. Here, she is a spy for Gekko State in the military, and helps them fight Dewey's plans, as well as facilitate in Dominic's Heel–Face Turn.
- Ace Pilot: As noted below, she was The Ace of New Wave until she left.
- Action Girl: She can hold her own both in an LFO and outside of one.
- Badass Adorable: A Genki Girl who's happy to brawl whether in an LFO or not.
- Bare Your Midriff: Both her outfit in New Wave and in New Vision.
- Battle Couple: With Sumner in New Vision.
- Big Eater: If the ramen-eating competition is any indication.
- Bluebird of Happiness: In Gravity Boys & Lifting Girl, she's associated with this for Gillian's little sister (with the bluebird itself being her Animal Motif back then).
- Boobs of Steel: The least fragile out of all the heroines in the E7 world, and has by far the largest chest.
- Broken Ace: She was The Ace of New Wave before Sumner, but possesses a deep-rooted insecurity of being dependent on others.
- Broken Bird: Not immediately obvious, but she's got a fair amount of issues underneath her energetic personality.
- The Cameo: Briefly appears in the anime alongside Sumner.
- Canon Immigrant: Started as a main character in the prequel video games (that are prequels to the anime) and then became a main character in the manga, which is an adaptation of the anime (albeit one that goes in a completely different direction).
- Dangerously Short Skirt: Wears one as part of her New Wave uniform, and unlike Gillian, she's happy to wield it to its full potential.
- Dark and Troubled Past: She's grown up on the streets and in poverty.
- Defector from Decadence: She left the military of her own volition once she realized how far the corruption ran.
- Does Not Like Men: Presumably due to growing up in the slums, she's not hugely fond of the male gender in Gravity Boys & Lifting Girl, citing them all to be idiots (or, to Gillian, perverts), though she doesn't outwardly express it much and seems to later abandon that mindset either way.
- Et Tu, Brute?: Flame's—that is, her old mentor's—betrayal sends her into a Heroic BSOD.
- Fiery Redhead: Her hair's a mix between red and brown (though considered red in the manga), and she's certainly got a loud personality to match.
- Genki Girl: Though it occasionally veers into Obfuscating Stupidity.
- Heroic BSOD:
- As a teenager, she falls into a depressed mood for quite some time after being outed as a girl as B.B.
- Upon realizing Flame's true nature, though she quickly snaps out of it.
- Honey Trap: She's not above seducing her targets to win their trust before she double-crosses them.
- Important Haircut: In Gravity Boys & Lifting Girl, where she cuts her hair as acceptance of her femininity with it now being too short to stuff her under cap.
- Jerk with a Heart of Gold: Though she's lost the grumpiness from her teenage days (in Gravity Boys & Lifting Girl), she's still prone to being flighty and inconsiderate. And like with Holland and Talho, said lack of consideration isn't exactly healthy for her love life.
- Manic Pixie Dream Girl: Played straight in New Wave, as the one who forces Sumner out of his comfort zone. Subverted in New Vision, where it becomes clear that she's got her own problems.
- Master of Disguise: She's sure fond of it, in any case.
- The Mole: What she was originally in the manga, before making her true allegiance known
- Obfuscating Stupidity: Typically to hide her true motives.
- Paper-Thin Disguise: Her disguises when she shows up before Sumner are half-hearted at best, and yet he still can't recognize her, even while actively thinking about her. Granted, this is probably more because of how Sumner is than anything.
- Passionate Sports Girl: In Gravity Boys & Lifting Girl, she lives to lift. Her passion dies down when she no longer needs it to escape her life, but she still has a fondness for it.
- Selective Obliviousness: She completely refuses to believe that Flame could be a villain until she has unrefutable evidence that he tried to have her killed.
- Short Tank: The Tomboy Love Interest to Sumner with the outfit to match.
- Spirited Competitor: She shows signs of this when initially refusing to take on a job as a pizza delivery guy... until she hears that they've got a 5-minute speed record.
- Street Urchin: She grew up on the streets, and as she notes that she can't remember a time when she wasn't independent, it's likely she's been an orphan for a long time.
- Stripperiffic: Especially jarring in the manga, where where she first appears as a conservatively dressed scientist, then switches to her New Wave outfit.
- Sweet Polly Oliver: As a teenager in Gravity Boys & Lifting Girl, since girls weren't allowed to participate in the lifting tournament.
- Tank-Top Tomboy: In New Vision.
- The Tease: She can be flirty at times.
- Tomboy and Girly Girl: The Tomboy to Gillian's Girly Girl.
- Tomboy with a Girly Streak: After embracing her femininity, she enjoys things like make-up and doesn't mind wearing mini skirts, but she's still a tomboy at heart, through and through.
- Tomboyish Ponytail: In New Vision.
- Took a Level in Cheerfulness: Over the course of Gravity Boys & Lifting Girl, she goes from a bitter punk to a Genki Girl.
- Troubled, but Cute: A female version, which puts a strain on her and Sumner's relationship, particularly in New Vision. As Sumner notes, most guys wouldn't even think of kissing a girl like her.
- Unsettling Gender Reveal: To the man who tried to assault her in prison while she was sleeping: suffice to say the guy noticed the "boy" was lacking certain... parts.
- Was It All a Lie?: Gillian asks this after discovering that Ruri is a girl and (falsely) assuming that she's given up lifting, though she admits afterwards that she wasn't really talking to Ruri (but rather venting her feelings about Sumner, having seen some of him in Ruri).
- Who Wears Short Shorts?: In New Wave.
One of Sumner's companions when he was a member of Sawyer Team. Between New Wave and New Vision, an experimental drug given to him by the military drives him insane, turning him into one of the main antagonists of the second game.
- Abusive Parents: When Steven was about to announce his intentions to go against his family's wishes (regarding his fate post-graduation) during his valedictorian speech, his father's response was to rush up to him and strike him in front of the entire audience.
- Alas, Poor Villain: Steven, Ruri, Gillian, and Hooky all mourn him after his death, both because he was their friend and because it wasn't entirely his fault to begin with.
- Arranged Marriage: In one with Gillian, though they apparently break it off sometime between New Wave and New Vision.
- Big Bad: One of them in New Vision.
- Black Sheep: Presumably became this for his family after choosing not to go to officer academy and instead joining up with New Wave.
- Crazy Jealous Guy: For the most part, he hides it well and doesn't let it interfere in his friendship with Sumner, but Steven's definitely taken notice of Gillian's feelings for Sumner. It's hinted to contribute to his Sanity Slippage in New Vision.
- Et Tu, Brute?: Sumner's defection is implied to have been one of the nails in the coffin for Steven.
- Lonely at the Top: Suggested towards the end of New Vision, where his insanity has its reached its peak and he seems genuinely glad to see Sumner and co. (who are there to take him down) and invites them to enjoy the view with him.
- Military Brat: Same story as Sumner.
- Nice Guy: He comes across as this in New Wave (having lost his uptight attitude from Gravity Boys & Lifting Girl), making his Sanity Slippage all the more tragic in New Vision.
- Not Quite Dead: Every time you might think the guy's been killed, he turns out to be alive.
- Not So Above It All: As a teenager, he initially comes across as a rule-abiding Student Council President, but he still helps referee Sind and Lotte's lifting match, and for all of his insistence that ghosts don't exist, he's just as easily freaked out when they think they see one.
- Psychopathic Manchild: Degrades into this once he starts having a Villainous Breakdown.
- Rebellious Spirit: He becomes a downplayed one towards the end of Gravity Boys & Lifting Girl. It may or may not have been what contributed to his Sanity Slippage much later on.

- Student Council President: During his high school years.
- Tragic Villain: In Ruri's words, he was ultimately another victim of CFS.
- Vitriolic Best Buds: With Hooky.

- White Hair, Black Heart: Averted in Gravity Boys & Lifting Girl and New Wave, but ultimately plays it straight as a Big Bad in New Vision.
- Yandere: Implied towards the end of New Vision, where he seems fixated on Gillian in particular (to the point of firing specifically at her when he attacks Sumner and co.).
One of Sumner's companions when he was a member of Sawyer Team, and Steven's fiancée. She works alongside Hooky in New Vision, where she hunts down the traitors Sumner and Ruri.
- Anti-Villain: In New Vision. She doesn't do anything honestly antagonistic and mostly acts as a harmless Punch Clock Villain (with a touch of It's Personal).
- Arranged Marriage: With Steven.
- Friendly Enemy: In New Vision, albeit with some prodding.
- Heel–Face Turn: In New Vision alongside Hooky.
- Her Heart Will Go On: A platonic version. Even after Gillian's sister dies, Ruri notes that Gillian keeps on lifting, "getting as high up to heaven as she can."
- Hidden Depths: The "Fair Lady" chapter reveals much about her mindset and personality when not revolving around her crush on Sumner. In-Universe, Ruri admits to herself that she might've been wrong about upper class girls like Gillian.
- Hopeless Suitor: Sumner didn't even realize she existed until they became teammates.
- Kill the Ones You Love: She's ultimately the one who pulls the trigger on Steven.

- Plucky Girl: Especially in Gravity Boys & Lifting Girl, where she continues to lift after her sister's death.
- Proper Tights with a Skirt: Invoked by her, disgusted at how revealing the female uniform for New Wave is.
- Smitten Teenage Girl: She was one for Sumner. As an adult, she keeps her feelings more subdued (partly because she's realized she doesn't really stand a chance).

- The Squadette: After Ruri leaves, she's the sole female member of New Wave/the Sawyer Team.
- Sugar and Ice Personality: Nicknamed "Miss Iron-Skirt" by Hooky for a reason. She tends to be uptight and came across as outright cold in her first meeting with Ruri, but she's a caring person underneath.
- Tomboy and Girly Girl: Girly Girl to Ruri's Tomboy.
- Unable to Cry: When Steven dies.
- What Does She See in Him?: Edie, her best friend (and a Childhood Friend of Sumner's) asks this regarding her feelings for Sumner.
- When You Coming Home, Dad?: Her father's shown to be frequently busy with work in Gravity Boys & Lifting Girl, though Gillian doesn't seem as affected by it as her little sister.
One of Sumner's companions when he was a member of Sawyer Team. Initially possessing a crush on Ruri, he considers Sumner his rival until Sumner beats him in a fight. During the timeskip between New Wave and New Vision, he's promoted to second lieutenant.
- Anti-Villain: In New Vision, as he remains pretty friendly with Sumner and co. in spite of everything.
- Cannot Talk to Women: Steven and Gillian have nicknamed him the Bashful Womanizer for this reason.
- Friendly Enemy: In New Vision. He's happy to have a ramen-eating competition with the very people he's supposed to be arresting.
- Funny Afro: When he's not wearing a hat. In Steven's words, that hair cannot be within military regulations.
- Graceful Loser: In spite of how obsessed he is over Ruri, he backs down just as promised after losing to Sumner.
- He Will Not Cry, So I Cry for Him: A gender-flipped version—he cries when Gillian can't.
- Headbutting Heroes: He and Shaun don't get along very well, due to a rocky history together. The two end up in outright blows while in Bester, before Sumner and Wes intervene.
- Heel–Face Turn: In New Vision alongside Gillian.
- Jerk with a Heart of Gold: For all of his bluster, he's a fairly amiable guy once he warms up to you.

- Stalker with a Crush: Towards Ruri at first. He gets over it quickly.
- Unknown Rival: To Sumner, who initially isn't even aware that Hooky is competing him with him for Ruri.
- Teeth-Clenched Teamwork: Again, with Shaun.
- Vitriolic Best Buds: With Steven.
One of Sumner's companions when he was a member of Sawyer Team, as well as being one of the first members.
- Everyone Has Standards: Chews out the vigilante corps in Bester for acting like bullies. And as Pez notes, Shaun couldn't stand copycats, making it highly unlikely he chose to use CFS of his own volition.
- Headbutting Heroes: With Hooky, as noted under his section.
- Heterosexual Life-Partners: With Pez.
- Idiot Hero: He has shades of this during his teenage years, being fairly thick-headed and reckless compared to Pez, Ruri, and even Hooky.
- Jerkass: Most of the time, and especially at first.
- Jerk with a Heart of Gold: However, he does have his nice moments. He's a loyal friend (who lays off some of the obnoxiousness once he warms up to you), and he's seen to be pretty displeased over the new corruption in his hometown of Bester.
- Not So Different: Ruri comes to think this way in Gravity Boys & Lifting Girl when she sees that even a bunch of punks like him and Pez have something they're working towards with all their effort.
- Odd Friendship: With Pez, who's his complete opposite in personality.
- Pet the Dog: In Gravity Boys & Lifting Girl, the first major sign of Shaun's heart of gold is him choosing to be a Secret Keeper for Ruri/B.B. for no reason other than not wanting to ruin a potential friendship.
- Sanity Slippage: Thanks to using the CFS in New Vision.
- Secret Keeper: Knew "B.B" was a girl, but chose not to use it against Ruri, citing to Pez that she would never let him be her friend if he did.
- Street Urchin: Gravity Boys & Lifting Girl reveals that he used to live on the streets with Pez.
- Teeth-Clenched Teamwork: With Hooky.
- Those Two Guys: With Pez.

Eureka's predecessor. Because she was a girl of mysterious power, the religious authority of Vodarac thought she was some sort of messiah and placed her in the central part of the temple. They banned any disciple from speaking to her, and allowed very few select disciples to care for her in a highly reverent, if sterile, manner. For forty years since her initial appearance, she had no significant contact with anyone. This changed when Norb was assigned to care for her.
