    Renton Thurston

Voiced by: Yuko Sanpei (JP), Johnny Yong Bosch (EN)

The main male protagonist. An ordinary boy bored with his ordinary life and with dreams of becoming a professional lifter, Renton's life is turned upside down when Eureka enters his life. He is one of the only people besides Eureka herself who can pilot the series's signature LFO, the Nirvash typeZERO.

  • 10-Minute Retirement: He quits as a member of Gekkostate after having his My God, What Have I Done? moment, but he's back into action by the time "Morning Glory" rolls around.
  • Ace Pilot: While he did have some initial trouble, Renton later proves to have some serious piloting talent.
  • Action Dad: Later in the series, Renton becomes the "papa" of Eureka's children.
  • Adoptive Peer Parent: In the epilogue, Eureka's children are adopted by Renton as well, who is 16, as Maurice, Maeter, and Linck all are shown to have the last name Thurston.
  • Adorkable: Is awkward and blushing around those he admires, and is nonetheless adorable despite it.
  • All-Loving Hero: If you live on the planet, Renton will want to protect you.
  • All of the Other Reindeer:
    • He was ridiculed by fellow classmates who thought of him as weird for always looking at his Compac Drive when it suddenly read "Eureka" or when he remembered his sister.
    • Renton also doesn't quite fit in with the crew of the Gekkostate. He eventually gains their respect, but especially Holland's, after the finale of "Morning Glory".
  • Always Save the Girl: No matter what happens, Renton will do anything to protect Eureka.
  • Ascended Fanboy: He greatly admired the crew of Gekkostate before becoming a member.
  • Badass Adorable: A cute, 14-year-old kid who becomes an Ace Pilot.
  • Badass Boast: During "Morning Glory," Renton delivers one to Holland when he tells that latter that he only came to the Gekko to look for Eureka.
  • Battle Couple: He eventually hooks up with Eureka — they both pilot the Nirvash together.
  • Be Careful What You Wish For: Renton desperately wished for a more "exciting life" and to become a Gekkostate member. However, the mess he got himself into and the poor treatment he received from the rest of Gekkostate had him question his earlier wishes
  • Berserk Button: Renton goes brutally psycho over his opponents during the finale of "Substance Abuse." It's because of his deadly combination of his love for Eureka, his resentment of Holland and frustration with his immaturity that makes him berserk instead of the Nirvash. The result: Blood, a dismembered arm, and a horrific scream.
  • Beware the Nice Ones: When he snaps, he snaps hard.
  • Big Damn Heroes: He pulls an epic one in "Morning Glory" to rescue Eureka towards the end of the episode.
  • Big Sister Worship: He deeply loved his older sister, Diane. Her memories has a profound effect on him.
  • Book Dumb: It's noted that his grades in school are pretty awful. However, he turns out to be a Teen Genius.
  • Brainy Brunette: He's a brunette and while he may be Book Dumb, he's also shown to be a Gadgeteer Genius.
  • Butt-Monkey: Deconstruction. For much of the first half of the anime, he is never safe from the Gekko crew's abuse, up to the point that he runs away. Fortunately, he returns to the Gekko after rescuing Eureka towards the end of "Morning Glory".
  • Can't Get Away with Nuthin': He tries to run away from Gekkostate all of one time... and happens to go to a rave... except he forgets that one of the members of Gekkostate was a formerly famous raver among the DJ circuit and the DJ at that particular rave happens to be someone he knows and tattles on him. Sheesh!
  • The Champion: His main motive is always to be Eureka's protector. She's the only reason he puts up with and come back to Gekkostate.
  • Character Development: Due to the impact of the war, seeing how the lives of everyone around him are affected, and understanding how everyone depends on him due to being The Chosen One to stop the war between the Scub Coral and humans, he gradually became more brave, mature, and confident in himself.
  • Character Tics: According to the DVD commentary of Episode 1, all males in the Thurston family snort when they become angry.
  • Chastity Couple: His romance with Eureka is one of the major elements of the story, but they don't even kiss until the final episode.
  • The Chosen One: A literal one. Eureka chose him by falling in love with him.
  • Classical Anti-Hero: At first, Renton starts off as an insecure, easily scared kid pushed around by the Gekkostate crew, especially Holland. He finally got tougher and more mature.
  • Costume Evolution: Renton discards the outfit he has worn for the last 49 episodes and dons a new one in the Grand Finale before going to save Eureka: He uses an entirely new jacket, loses the fanny pack, sports black shoes with red lines, and dark pants.
  • Death Glare: In "Morning Glory", he gives one to Holland upon his return to the Gekkostate, especially when he does his Badass Boast.
  • Declaration of Protection: He swears to protect Eureka.
  • Determinator:
    • Renton is a person with strong resolve who is willing to do anything to accomplish something that is important to him without hesitation.
    • In the manga, he gets shot in the gut and stabbed by enemy soldiers, but managed to carry Eureka around for a bit before passing out and later pilots the Nirvash while still injured.
  • Devoted to You: Once she finally reciprocates his feelings, Eureka becomes hopelessly devoted to him and can barely stand being away from him.
  • The Dog Bites Back: By the second half of the series, Renton rebels against Holland to the point that he decides to give the latter a Badass Boast and rescue Eureka himself.
  • Dogged Nice Guy: To Eureka. He falls for her at first sight, but waits patiently a long time for her to return his feelings.
  • Dude, Where's My Respect?: Despite some of the things he has done for them, everyone at Gekkostate (sans Eureka) hardly show him the respect he deserves. At first. All of his respect is gained by the time "Morning Glory" rolls around.
  • The Dulcinea Effect: He's ready to do anything to protect Eureka even when he just met her and doesn't even know her name.
  • Et Tu, Brute?: His reaction to the Beams' true intentions to kill Eureka and the Gekkostate, Holland included.
  • Expository Hairstyle Change: His hairstyle starts to be different during the final episodes of the anime, which probably signifies his Coming of Age.
  • Extreme Doormat: Early on, basically becomes one of these constantly whenever his relationship with Eureka is brought up, and rather ruthlessly taken advantage of by her kids in episode 6.
  • Failure Hero: Momentarily feels like this in the finale, thinking he failed to save his father, his sister, and Eureka.
  • Friendless Background: He doesn't appear to have any friends, which is further implied in his inability to pass the ball in soccer as he never actually had anyone to play with.
  • The Friend Nobody Likes: Almost everyone on the Gekko has expressed dismay about his quirks when he first joins, at least until he gains their respect by the time of "Morning Glory".
  • Gadgeteer Genius: Though it doesn't come up much, Renton is a very competent mechanic. He disassembles Dominic's bike in mere moments to blackmail him, knowing Dominic couldn't fix it without him.
  • Good Parents: His response after Maurice points a gun at him, is to say he loves him as much as Eureka does, and he'll always do his best for him.
  • Heroic BSoD:
  • Hidden Depths:
    • Renton was introduced as Book Dumb in the first episode, but it's later revealed that he's actually a genius, see his Teen Genius section for more details.
    • He shows surprising skill at soccer.
  • Human Pack Mule: When he goes shopping with Talho and Eureka.
  • I Am What I Am: Says this a lot, especially as he tried to climb out of his father's shadow early in the series.
  • Idiot Hero: "Idiot" is a stretch. All of his failures come from naïvete and he gets over it thanks to Character Development.
  • I Got Bigger: In seasons three and four, he noticeably grows taller and mature, which is mentioned by several members of the Gekkostate on numerous occasions. By the time he is 16, he has matured considerably and nearly overtowers Eureka, who had been about the same height as him.
  • I Just Want to Be Special: The first episode has Renton monologue about how dull his entire life has been and his desire to do something worthwhile.
  • Innocent Blue Eyes: Which serve to represent his initial naïvete in the beginning.
  • Innocently Insensitive: He makes comments about the importance of image that get Eureka reasonably self-conscious about her scars and he doesn't realize it. He also says her Cosmetic Catastrophe is awful without realizing she was trying to look pretty for him.
  • Insecure Love Interest: The first half of the series has Renton fear Eureka thinks of him as "uncool" or "pathetic".
  • Interspecies Romance: He (human) and Eureka (Coralian).
  • I Will Wait for You: In the manga ending, Renton refuses to acknowledge that Eureka is dead after the Scub Coral leaves the planet and will continue to wait upon the day she returns to him. The final page indicates they might have finally reunited after 2 years.
  • Jumped at the Call: Deconstruction. Renton's decision to quickly join the Gekkostate, the crew he's admired for a long time, comes back to bite him later on. One, he doesn't know exactly what they're doing on their journeys. Second, he never took into account that badly they would treat him.
  • Kid Hero: 14-years-old at the beginning and the main male protagonist.
  • Like a Son to Me: The Beams genuinely cared about him and thought of him as a surrogate son.
  • Living Emotional Crutch: To Eureka. After he flees from Gekkostate, she is constantly in grief at Renton's absence and determined to see him to the point that she departed from Gekko behind everyone's back, including her three kids, to find Renton. She was finally emotionally at ease when she was reunited with Renton.
  • Love at First Sight: He falls deeply in love with Eureka the moment she crashlands near his grandfather's house.
  • Missing Mom: Renton's mom is only mentioned twice in the original series, in the first episode as being deceased by Axel as he mentions withdrawing Renton from school and wondering how he's going to ever explain it to her (which depresses Renton), and in Episode 15, when he goes to the place where his dad supposedly met her and fell in love and encounters her brother, his uncle Yucatan Iglesias. It is implied but never said upfront that his birth resulted in his mother's death. Matthieu should have kept his mouth shut when he asked if his mom taught him manners, 'cause poor Renton didn't get to have a mommy. Such is made clear when the photo of Adroc holding baby Renton lacks a mother. The final episode reveals a family record indicating a Blau Thurston (presumably Blau Iglesias Thurston) was Adroc's spouse and is deceased, her date of death implying she died giving birth to Renton.
  • My God, What Have I Done?: When saving Holland, he goes insane and pounds a KLF into pulp. A bloody arm with a wedding band attached drops out, clicking the realization that he has been killing people and has killed someone. Causes These Hands Have Killed which results in Thou Shalt Not Kill.
  • 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.
  • Naïve 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.
  • Nice Guy: He is a very outgoing and emotional person possessing strong ideals and compassion.
  • Nice Shoes: Renton uses a pair of sporty sneakers called Clies throughout the series and freaks out whenever bad things happen to them like when they are scorched. By the very end of the first series, his shoes are worn out to the point of total ruin, with the tips beginning to tear loose from the bottoms. And Renton couldn't give a damn if they were in tatters, because by this point, his childish cares have all been overridden with a desire to be there for Eureka. Instead, he dons totally new shoes and ditches the ratty Clies for good, a symbolic shedding of his childhood and Coming of Age.
  • Not So Different: With Maurice, Maeter, and Linck. He realizes that they act so bratty to him is because their afraid of him taking Eureka away from them. The exact same thing he did when his sister went out on dates.
  • One Head Taller: He's taller than Eureka once he turns 16.
  • Primary-Color Champion: His attire, pre- and post-Costume Evolution, are colored with white, red, and blue.
  • Prodigal Hero: He avoids Gekkostate for a while after realizing that he accidentally killed innocent people. Then, by the time of "Morning Glory", Renton returns to the Gekko and rescues Eureka.
  • The Protagonist: He's the main focal character of the series.
  • Rage Against the Mentor: By the time of "Morning Glory", he's willing to call out Holland on his behavior after he returns to the Gekko to search for Eureka.
  • Raised by Grandparents: Grandfather, rather. Sister, too, except she disappeared some time later.
  • Red Is Heroic: Red is his main color scheme — on the sleeves of his jackets, lining of his hover board, and linings of his shoes.
  • Replacement Goldfish: It can be argued that the Beams, who were unable to have children of their own, saw Renton as this.
  • Screw This, I'm Outta Here!: Subverted. After his My God, What Have I Done? moment, he decides enough is enough and flees from Gekkostate. But it doesn't last and he decides to return for Eureka.
  • Shipper on Deck: With Eureka, Renton helped Anemone understand her feelings for Dominic.
  • Single-Target Sexuality: The first novel, Blue Monday, reveals Renton only went on one date with a classmate, but never had any romantic feelings for any girl until he met Eureka.
  • Strong Family Resemblance: Images of Adroc show that Renton took all of his looks from his father, the only difference being that Adroc is more older looking and has a mustache.
  • Teen Genius: Renton is a teenager and his genius is seen with his skills in mechanical engineering, his ability to pilot Nirvash, and when he invents the first IFO by combining his knowledge of the Scub Coral and LFOs.
  • These Hands Have Killed: He completely flips when he realizes that there were people inside the KLFs he was destroying, and never quite gets over it. He eventually takes up a Thou Shalt Not Kill stance.
  • Thou Shalt Not Kill: Eventually takes this stance. The anime finale shows him making one exception to this to destroy the antibody Coralians threatening the Gekko before heading off to save Eureka.
  • Tiny Schoolboy: Downplayed. The first novel, Blue Monday, reveals Renton is the third shortest boy in his school.
  • Took a Level in Badass: At first, he was throwing up in the cockpit in the earlier episodes. He eventually becomes the savior of the world by the finale.
  • Took a Level in Cynic: While always an idealist in the end, he goes through the process of shifting from an Ascended Fanboy to realizing what kind of mess he's really gotten himself into.
  • Tragic Keepsake: He keeps Charles' wedding ring with him all the way up to the finale, as a reminder of the world he wants to save.
  • Understanding Boyfriend: After Eureka is revealed as a Coralian, Renton does not reject her as she feared but rather accepts her for who she is, not what she is.
  • "Well Done, Son!" Guy:
    • Though somewhat of a celebrity, being the son of a savior, Renton feels uncomfortable being the son of Adroc Thurston. His surname is recognized everywhere he travels, and he constantly feels as if he lives in his father's shadow. At first, anyway.
    • He wants to earn the approval of the Gekkostate crew and eventually does so by the time of "Morning Glory".
  • Wide-Eyed Idealist: He had a rather idealistic, but naïve outlook on the world and Gekkostate. Thank to character development, he gained a more realistic view.


Voiced by: Kaori Nazuka (JP), Stephanie Sheh (EN)

The main female protagonist. Eureka is a mysterious girl with an affinity for machines who has trouble opening up to other people until she crash-lands her LFO, the Nirvash, on Renton's house.

  • Ace Pilot: She was a very experienced LFO pilot to begin with. She begins to falter in her skills as her depression grows worse and worse, and she seems to eventually retire from piloting altogether.
  • Action Girl: She's a very competent pilot.
  • Action Girlfriend: Her arrival changes Renton's life and allows him to join Gekkostate and become Nirvash's pilot.
  • Action Mom: Though her children are clearly adopted.
  • Adoptive Peer Parent: Eureka has three adopted children and she's only about 14-16. What's more, they're the children of some people she killed when she was in the SOF. Her horror at her actions prompted her Heel–Face Turn, so she adopted them.
  • The Ageless: Her physical age never changes, as shown in flashbacks set nearly a decade earlier.
  • Anti-Hero: To an extent, with some byronic traits. She's rude, cold, standoffish, and until very late in the series has no problems killing people if it means lining the Gekkostate's wallet. She amends her ways as she becomes closer to Renton.
  • The Atoner: Has shades of this in regards to her past in the SOF, and it becomes amplified when the Antibody Coralians show up and start killing people.
  • Badass Adorable: A cute, Mystical Waif who is an Ace Pilot.
  • Battle Couple: With Renton — they both pilot the Nirvash together.
  • Beauty Is Never Tarnished: Averted pretty hard. After her close call with being encased in scub, Eureka gets some nasty-looking scars that last for quite some time, her hair is left as a short, jagged mess and she loses her eyebrows. She gets understandably self-conscious about it.
  • Belated Love Epiphany: Eureka realizes her feelings for Renton upon learning of his departure in episode 24.
  • Bizarre Alien Biology: She does not age - or at least does so at a much slower rate than humans, has a transparent, neon green layer of skin under her outermost layer, eventually sprouts wings, etc. It furthers her feelings of alienation from others due to her obviously nonhuman nature.
  • Blank Slate: The reason for her existence. The Coralians wanted to know what humans would write on the slate.
  • Blue-and-Orange Morality: Along with concepts such as love, Eureka doesn't understand morality in the same way humans do - this is another thing Renton helps her clear up, and understanding the gravity of her actions leads her into a breakdown that lasts much of the series.
  • Blue Is Heroic: Eureka's main color scheme is blue.
  • Body Horror: When Eureka's Coralian features begin to show towards the end of the series, one of the first stages of her transformation included growing giant luminescent boils growing all over the left side of her body.
  • The Cameo: In New Wave, she shows up at the end, after Sumner delivers the Nirvash to her and Holland.
  • Character Development: As time goes by, she begins to act less a socially awkward girl and more like an actual person as parts of her human side begin to emerge.
  • Character Exaggeration: The manga plays up her Emotionless Girl aspect in the beginning. She's more stoic and emotionally distant, even to her children.
  • Character Title: Her name gives the anime (and manga) its title.
  • Chaste Heroine: At first, she doesn't know a thing about romance. She doesn't even know how to get pregnant with a baby. She does grow out of it as she falls in love with Renton.
  • Chastity Couple: Her romance with Renton is one of the major elements of the story, but they don't even kiss until the final episode.
  • The Chooser of The One: She chooses Renton to be her partner after realizing she's in love with him.
  • Cloudcuckoolander: She is introduced when she accidentally demolishes Renton's home, and later burns what is left of it so its soul can move on. Steadily gets deconstructed, as her inability to fit in with others actually bothers her immensely.
  • The Comically Serious: The "comically" part is stretched, but her serious attitude is often contrasted with her more laid-back allies for laughs from time to time.
  • Cosmetic Catastrophe: In Episode 36, Eureka tries out makeup in an attempt to look pretty for Renton. This backfires as she ends up looking like a clown and Renton even asks her if her children did that to her as a prank.
  • Cry Cute: In the manga, the first time she shows emotion is when she breaks down in tears after she confesses her dark past as a soldier to Renton.
  • Dark and Troubled Past: She was once a Child Soldier and killed people as a result.
  • Defector from Decadence: She abandoned the SDF with Holland prior to the beginning of the series because she realized they were making her kill for evil.
  • Defrosting Ice Queen: Falling in love with Renton makes Eureka open up emotionally and develop her humanity. It's present in the anime, but the manga takes this Up to Eleven by making her a full-blown Emotionless Girl in the beginning instead of merely reserved and socially awkward.
  • Demonic Possession: In the manga, Eureka is briefly possessed by a Coralian "ghost" in order to bring her and Renton to the Scub Coral.
  • Deuteragonist: Eureka's the secondary focal character after Renton.
  • Devoted to You: Renton falls desperately in love with her the moment he meets her, no caring to put up with her initial lack of interest in him and Gekkostate crew's constant abuse just so he can be by her side and protect her.
  • Died in Your Arms Tonight: In the manga, she Disappears into Light in Renton's arms.
  • Disappears into Light: Her ultimate fate in the manga. Upon the Scub Coral's demise, Eureka's body disintegrates into lights. However, whether she's actually dead is left ambiguous.
  • Disappointed in You: By "Morning Glory", she doesn't even bother to show how disappointed she is in Holland for what he's done.
  • Emotionless Girl: She originally didn't emote at all and only went along with the orders she was given. She started developing emotions after adopting her children, but she still had some difficulty understanding and expressing them until she fell in love with Renton. This gets played up in the manga.
  • Exotic Eye Designs: Eureka has a circle parallel to the iris.
  • Expository Hairstyle Change: She gets several hairstyle changes reflecting... other changes about her.
  • Flower in Her Hair: In the final episode, the hairclip that Renton puts on Eureka has a flower on it.
  • Freakiness Shame: When Eureka's Coralian attributes begin to manifest themselves, her left arm sheds its skin and she grows a pair of green, butterfly-like wings. At first, she is worried Renton will reject her new form, but Renton admires her new wings and thinks she has become even more beautiful.
  • Friendless Background: She doesn't have any friends, though doesn't seem to mind. Her companionship with her fellow pilot Renton becomes her first real human contact.
  • Good Is Not Nice: She's kind and, eventually, a pacifist, but her coldness and lack of social aptitude renders her intimidating - Matthieu lampshades this, stating that she simply isn't approachable.
  • Good Parents: She starts out inexperienced and aloof, but she loves her adopted kids dearly. Her real test comes when Maurice points a gun on Renton. She gently talks him down, reaffirms how much she loves him, and rescues him from doing something he'd regret for the rest of his life.
  • Go Out with a Smile: In the manga, she smiles at Renton before she Disappears into Light.
  • Growing Wings: In the final episodes, Eureka undergoes a mysterious transformation that includes the sprouting of bright green butterfly wings in her back.
  • Hair Reboot: She spends a significant portion (episodes 21-41) of the series with her hair as the short, jagged mess left behind after her close call with being encased in scub, but it grows back instantly when she speaks with Sakuya.
  • Heroic BSoD: In the manga, when Renton, in his own Heroic BSoD, told her to leave him alone when she tried giving him some fruits to cheer him up.
  • Heroic Self-Deprecation: Fairly early on she sinks into part of the Coral Scub, almost dying in the process, though in her lamentation states that she would absolutely deserve such.
  • Human Alien: A Coralian in human form.
  • I Just Want to Be Beautiful: In Episode 36, she tries to make herself look prettier upon realizing the importance of beauty and due to being somewhat disfigured at the time. After a Cosmetic Catastrophe incident, Renton lets her know she doesn't have to change her appearance to make him like her because he already loves her for who she is.
  • Ill Girl: She often suffers from chronic headaches and by the end of the first half, her mental and physical health have deteriorated to point where she can barely stand. This was probably due to the fact that her connection to the Nirvash was deteriorating and she felt that it was favoring Renton as it's pilot rather than herself. Plus, her ailments really put her over the edge after she comes in contact with the Coralians in Episode 11.
  • Innocently Insensitive: Introduced this way - she burns the remains of Renton's home down, and when he objects to this she simply smiles. It later turns out she was trying to help, somehow.
  • Interspecies Romance: She (Coralian) and Renton (human).
  • I Will Find You: Upon realizing that Holland is unable to search for Renton, Eureka sets off to do it herself.
  • Love Hurts: In the manga, she learns how much it can hurt to love someone when Renton hurts her feelings during his Heroic BSoD. It goes to the point where she temporarily decides to never care about anyone again so she doesn't have to feel pain anymore.
  • Machine Empathy: She's in tune with the Nirvash's feelings. She also treats any other machine as a living thing.
  • Maternally Challenged: She's raising three orphans despite knowing little to nothing about taking care of kids. As a result, she spoils them and gets them presents that aren't too appropriate, such as textbooks that are too advanced for them.
  • Messy Hair: She loses a significant amount of hair after being absorbed by the Scub Coral in the 19th episode and what is left of it is rather messy. After episode 41, it grows back to a bob haircut.
  • Modesty Shorts: She wears a pair of shorts under her short dress.
  • Morality Pet: To Holland. Besides Talho, Eureka is the only one of Gekkostate that Holland doesn't take his anger out on.
  • My God, What Have I Done?: The first emotion she ever experienced 3 years ago was horror at the inhumane act she committed when she realized she orphaned the three children she would later adopt.
  • Mystical Waif: The enigma that she presents - at first what and who exactly she is, and later why the Coral Scub would create her in order to interact with humans - is a major plot element.
  • No Brows: She loses her eyebrows after being absorbed by the Scub Coral. She regains them after talking to Sakuya, along with her hair growing back to a bob haircut.
  • No Social Skills: Due to her backstory as a Tyke-Bomb, she does not even know what is "cool", what love is and how to be pregnant with a baby. She eventually becomes a more sociable person towards the end of the series, thanks to the influence of Renton.
  • Non-Human Lover Reveal: She is later revealed as a Coralian and fears that Renton will reject her, but he rather accepts her for who she is, not what she is.
  • Not Good with People: Seems to be more in touch with machines than humans.
  • Painful Transformation: Growing large, green wings out of your back is not a pleasant experience.
  • Parental Substitute: She's an adoptive mother to Linck, Maeter and Maurice. In a dark twist, it's because she orphaned them.
  • Phlebotinum Girl: A young alien girl and the key to piloting the Nirvash who was used and manipulated by the government and blindly followed their orders until she realized what she was doing was wrong and defected along with Holland.
  • Pinocchio Syndrome: Eureka attempts to become more "human" in several ways, though they all tend to backfire on her.
  • Protectorate: Renton's main motivation is to protect Eureka.
  • The Quiet One: At first. She becomes more talkative as she becomes more human, though only around Renton - she's practically a wall compared to her copilots.
  • Red Oni, Blue Oni: The blue (quiet, reserved, and calm) to Anemone's red (loud, emotional, and violent).
  • Rei Ayanami Expy: Short light bluish hair, purple eyes, pale skin, Humongous Mecha pilot, Human Alien, Mystical Waif, No Social Skills, an Ill Girl, her boss is the only person she's close to until she falls in love with the main character and started off as an Emotionless Girl as a result of her Tyke-Bomb upbringing, prior to a traumatic event that would trigger her Character Development, which then was accelerated much further by meeting her Love Interest.
  • Safety in Indifference: In the manga, after realizing Love Hurts, she goes through a period of refusing to feel, deciding that it's easier than leaving herself vulnerable.
  • Scars Are Forever: Before leaving Sakuya's Heart, Eureka is offered to have her scars from being absorbed by the Scub Coral fixed but she declines saying that these scars are the outward proof of what she has been through. Upon emerging, Eureka's scars remain, but they have become less prevalent.
  • Secondary Character Title: Her name is the series' title, but she's the deuteragonist.
  • Shipper on Deck: With Renton, Eureka helped Anemone understand her feelings for Dominic.
  • Shy Blue-Haired Girl: More reserved than socially anxious, though she's very wary of others and until meeting Renton generally refused to interact with anyone but her kids and Holland.
  • Single-Target Sexuality: Eureka was an Emotionless Girl who hardly emote to anyone that wasn't her children. However, falling in love with Renton helped her to show more of her emotions. And Renton is the only person that Eureka has ever fallen in love with.
  • Single Woman Seeks Good Man: She falls for Renton because of his good-nature and sensitive personality.
  • The Spock: Between her attempts to understand the humans around her and logical, inquisitive personality, she fits this trope to a T.
  • The Stoic: Her calm, level headed personality and approach to battle makes her an extremely talented pilot, though she's overly serious and boring in everyday conversation. She gradually learns how to show her emotions to others, though with a huge amount of difficulty.
  • Sugar-and-Ice Personality: At first, she mostly comes off as reserved and emotionally distant due to her lack of understanding of human feelings, yet she's a kind and motherly girl. Eventually, her warmer personality takes over.
  • Technicolor Eyes: A sign that she's not human.
  • Thou Shalt Not Kill: Like Renton, she eventually decides to fight this way.
  • Token Non-Human: A Coralian member of Gekkostate.
  • Took a Level in Cheerfulness: She originally was an Emotionless Girl before the beginning of the anime. She began to develop emotions after adopting her three children, but remained emotionally distant of others. Meeting and falling in love with Renton turns her into a much more cheerful and open girl.
  • Traumatic Haircut: After being absorbed by scub, her hair is left in kind of a unkempt pixie cut style. When she emerges after talking with Sayaka in Episode 41, her hair grows back into a bob hairstyle.
  • Tyke-Bomb: She was used by the government and trained to kill almost remorselessly, until one day, when she was checking a pile of corpses looking for wounded people to finish off, she found three orphans, had a huge epiphany, and decided then and there to adopt them and defect from the military.
  • Uncertain Doom: In the manga, Eureka Disappears into Light and is presumed dead after the Scub Coral's demise. However, Renton refuses to believe Eureka is dead and the final page implies Eureka reunited with Renton eventually.
  • Undying Loyalty: Had this towards Ardroc Thurston, Renton's father, during the time he was alive.
  • Unkempt Beauty: She is this for a good part of the series after being encased in scub. Her hair gets messy and she loses her eyebrows, but she still looks decently cute. However, Eureka eventually starts to worry she might not look good enough for Renton.
  • What Is This Thing You Call "Love"?: Being an Emotionless Girl representative of the Coralians, Eureka is extremely confused by the concept of romantic love until she begins to fall in love with Renton. However, she seems to have figured out familial love on her own thanks to her adopted children.
  • When She Smiles: Gets into the habit of smiling, though she prefers a more vacant expression.
  • Winged Humanoid: After her "big change" in the last few episodes, Eureka grows wings in her back.
  • You Gotta Have Blue Hair: Eureka has turquoise hair.
  • You Kill It, You Bought It: After killing their parents, she took the kids in and is raising them.
  • Younger than She Looks: She emerged from the Scub Coral looking roughly 14 years old and ages at a slowed rate. She is estimated to be biologically about 16 years old by the time Renton arrives aboard the Gekko, but is chronologically the same age as him, right down to the day.

    Captain Holland Novak

Voiced by: Keiji Fujiwara (JP, 2005-2009), Toshiyuki Morikawa (JP, 2017-present), Crispin Freeman (EN)

The leader of Gekkostate. Holland was once a Captain of the SOF, but defected and formed an anti-government movement. To the public, he is known as the world's top amateur lifter and is Renton's longtime idol. He pilots the Terminus typeR909, and later the Terminus typeB303 Devilfish.

  • 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 Nice Guy: He is a lot less of a Jerkass and much more laid back in the manga.
  • Aloof Big Brother: Holland's often dismissive of Renton to the point where he attacks whenever he's angry at himself. At first. By the time Renton decides to rescue Eureka in "Morning Glory", Holland lets go of his childish nature and starts being a stern, fatherly figure to Renton.
  • Always Second Best: No matter how much effort he put into it, he would never become The Chosen One.
  • An Arm and a Leg: In the manga, he loses his right arm during his final battle with Dewey.
  • The Atoner: For his actions as an SOF member, his initial resentment towards Renton, and how he almost caused the Gekkostate to be dissolved.
  • Authority Equals Asskicking: He is the leader of Gekkostate and an extremely skilled pilot and fighter.
  • Badass Baritone: Provided by both Keiji Fujiwara in Japanese and Crispin Freeman in English.
  • Bad Dreams: In one episode, he has a nightmare of the atrocities he committed while part of the SOF.
  • Big Brother Worship: He was said to have idolized Dewey and never realized the deep hatred his older brother harbored towards him. His affection for Dewey was such that Holland even joined the military with him, and was made a unit leader.
  • Big Good: The leader of the main heroes.
  • 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.
  • Break the Haughty: He undergoes a big one during the end of "Morning Glory". He's initially a jerk who refuses to accept that he isn't The Chosen One for Eureka, attempts to deny her relationship with Renton and also to run away his past and responsibility as the leader of Gekkostate. In "Morning Glory", Eureka is able to call him out on his abuse with Renton just before the latter returns to tell Holland that he only came for Eureka's sake. When Renton rescues Eureka at the end of the episode, Holland finally realizes that Renton is The Chosen One and becomes a more responsible leader.
  • 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.
  • Cain and Abel: The Abel to Dewey's Cain.
  • The Cameo: He makes a brief appearance in Gravity Boys & Lifting Girl to compliment Sumner on his lifting.
  • Character Development: Holland is introduced as a jealous jerkass who tries to get Renton out of the picture in the first half of the series so he can be partners with Eureka. After "Morning Glory," he becomes a more mature and caring individual, 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.
  • Dark and Troubled Past: A soldier who was ordered to kill innocent people. Before that, his parents were dead by the time he was a child. Afterwards, he had to find out that his older brother hated him.
  • Deadly Upgrade: Swaps to the 303 in the last act of the series, which requires extremely dangerous drugs just to pilot the thing.
  • Deadpan Snarker: He has no shortage of barbs to trade.
  • Declaration of Protection: After his Character Development kicks in, he swears to do whatever it takes to protect Renton and Eureka.
  • Defector from Decadence: In the past, when he betrayed the military.
  • Determinator: In the manga, he will bring back the Amita Drive to Renton and Eureka, even if he has to crawl his way back after being attacked by TheEnd.
  • Dislikes the New Guy: More than anyone else, Holland is resentful of Renton joining the Gekko to the point that he beats the crap out of him whenever things go wrong. However, Holland eventually reconsiders his opinion after he realizes that Renton and Eureka are meant to be together.
  • Driven by Envy: What drives him throughout the first half of the series is his jealousy of Renton for being The Chosen One for Eureka.
  • Easily Forgiven: Both Renton and Eureka have forgiven Holland for how hard he was on them by the time of the second half of the series.
  • Familial Reveal: His last name is Novak; he's the younger brother of Dewey Novak.
  • Fatal Flaw: Holland has two: his first flaw is his wrath, and his second flaw is his willingness to run away from his past and responsibility. His temper got the best of him when he attempted to deny Renton's relationship with Eureka as The Chosen One. By the time Eureka called Holland out for what he did, it was already too late and Renton joined with Ray and Charles. Meanwhile, Holland's actions leads Gekkostate straight into a state army trap that takes advantage of this tragic instinct of his until Renton and Eureka's actions and reunion rescue the team in the finale of "Morning Glory". 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 bitter resentment towards Renton in the beginning.
  • Good Is Not Nice: Holland is on the side of good for sure. However, he spends the first two seasons being a jerk to his crew (save Eureka and Talho), even being physically and emotionally abusive to Renton. Luckily, he gets over it during the finale of "Morning Glory".
  • Graceful Loser: A heroic example. After listening in on Renton and Eureka's conversation in "Morning Glory", he calmly accepts defeat and realizes that Renton is The Chosen One after all.
  • Green-Eyed Monster: When Renton is chosen over him to become The Chosen One for Eureka, Holland does a bad job of hiding his jealousy of Renton.
  • Hair-Trigger Temper: In the first half of the series, he can barely stand in the same room as Renton before lashing out. At least initially.
  • Heartbroken Badass: He had a messy first relationship with Diane Thurston, 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.
  • His Own Worst Enemy: Let's face it, things would have work out much better in the first half of the series, had he learn to accept that there are ways for him to help save the world and stop Dewey, besides being Eureka's chosen partner, instead of always running away and letting his bitter feelings build up.
  • Jerkass Realization: After Renton returns to rescue Eureka in "Morning Glory", he immediately regrets how he was a jerk to Renton and everyone else at the Gekkostate and decides to make up for his actions.
  • Jerk with a Heart of Gold: Even though he has a temper and may overreact, Holland's a good guy underneath it all and is not afraid to admit when he's wrong.
  • Kick the Dog: Slap the ignorant hero around, Holland! Such a great way to win his loyalty and impress your crew!
  • Large Ham: He tends to be bombastic with his speeches, especially during battles.
  • Laser-Guided Karma: As sad as it is, when you remember how much damage he's done to the crew, especially to Eureka and Renton, over the past two seasons, it is possible that his leg being wounded to the point where he may never be able to truly lift ride again, may be his comeuppance for the actions that lead to said wound.
  • The Leader: He's the captain of Gekkostate.
  • Living Legend: By far and away one of the most famous people in the entire world.
  • Manchild: 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. Fortunately, he grows out of this after "Morning Glory".
  • The Masochism Tango: With Talho. They eventually work things out.
  • Must Make Amends: After "Morning Glory", he decides to reconcile with his fellow shipmates aboard the Gekko, as well as Renton and Eureka.
  • My God, What Have I Done?: Holland's reaction after Eureka and Renton see through the latter's bull makes him realize that he's throwing the crew's lives away, given how he acted.
  • Overprotective Dad: He's a father figure to Eureka to the point that he resorts to beating up Renton, Moondoggie and Matthieu in "Date of Birth" over a poorly-worded statement made by her.
    Holland: [lifts Renton up by the collar] Damn you! What the hell did you do to Eureka?! [cue him giving Renton, Moondoggie and Matthieu Amusing Injuries]
  • Papa Wolf: In the second half of the series, Holland does everything in his power to protect Eureka and Renton from Dewey and his enemies. In "Date of Birth", he beats the crap out of Renton, Moondoggie and Matthieu due to a misunderstanding caused by Eureka.
  • Parental Substitute: His interactions with Eureka and eventually, Renton, are reminiscent of a father and his children.
  • Pet the Dog: After Renton rescues Eureka in "Morning Glory", Holland apologizes to them and makes up for the damage his actions have caused.
  • Reasonable Authority Figure: He has a very reasonable judgment and is always willing to listen to Renton, even if he initially didn't trust him.
  • The Resenter: He initially resents Renton for his relationship with Eureka. It gets thrown out the window when Renton rescues Eureka in "Morning Glory".
  • Screaming Warrior: Likes to scream while charging into the fray.
  • Screw This, I'm Outta Here!: He defects from the military along with Eureka in his backstory.
  • Second Love: To Talho, possibly. It's hinted near the end that she was in a previous relationship with Dewey, Holland's older brother, before becoming a couple with the latter.
  • Self-Fulfilling Prophecy: Holland, attempting to deny Eureka's relationship with Renton, only ends up causing Renton to become The Chosen One for Eureka regardless of his actions.
  • Sergeant Rock: Sure, Holland might be a major jerk at times, but he's respected and liked by the Gekkostate crew because he's competent, wouldn't have them do something he wouldn't do himself, and despite his outward jerkassery (especially in the first half of the series), is rather concerned for their welfare.
  • Shameless Fanservice Guy: While inside the Gekko he wears nothing but his underwear. Since the ship is his home, he doesn't see anything wrong with it.
  • Smoking Is Cool: In the manga and novels, he is a smoker, unlike his anime counterpart.

    Talho Yuki
Click here for her second outfit 

Voiced by: Michiko Neya (JP), Kate Higgins (EN)

The pilot of Gekkostate's ship, the Gekko, and cover-girl for their magazine Ray=out. In a relationship with Holland.

  • Adaptational Nice Guy: Much like Holland, Talho is much nicer and more mature in the manga. It helps all her jealousy issues and insecurities regarding Holland are gone in that adaptation.
  • The Alcoholic: She was a heavy drinker in the first half of the series.
  • All Girls Want Bad Boys: Talho's relationship with Holland, but even that is tempered by her insistence that he act more maturely.

  • Bare Your Midriff: Before her character development.
  • Be a Whore to Get Your Man: She reveals in episode 30 that her personality and revealing dress style was to capture and maintain Holland's attention and love. Once she gets over her insecurities, she starts dressing up more modestly.
  • Character Development: After "Morning Glory", she decides to become the person she used to be before the Gekkostate and becomes more mature, kind, and caring towards the crew.
  • Clingy Jealous Girl: The root of her issues is that she can't stand the mere thought of Holland paying more attention to Eureka than her and the fact that she's afraid that he hasn't gotten over his feelings for Diane yet.
  • Color Motifs: Talho's two main outfits consisted of purple and white.
  • Cool Big Sis: She teases and advises the younger members of Gekkostate. Moreso after her Character Development, after which she grows into more of a Team Mom.
  • Dangerously Short Skirt: Before her character development.
  • Expository Hairstyle Change: As a result of realizing her own immaturity and displeasure with the kind of person she has been recently, she undergoes a physical and emotional change. She ditches her Stripperiffic look for a more conservative one, including cutting her hair.
  • Facial Markings: The flower tattoo on her left cheek.
  • 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.
  • Hand on Womb: Does this very frequently after she discovers she's pregnant.
  • Heterosexual Life-Partners: Best friends with Hilda.
  • Important Haircut: Talho trims her normally unkempt hair as part of her complete outer (and inner) makeover in episode 30.
  • Insecure Love Interest: One of the reason her relationship with Holland was initially rocky was because of Holland's dedication to protect Eureka and his past relationship with Diane made her feel very insecure.
  • Lethal Chef: She tried to cook in the manga and ruined the kitchen so badly that she made cup ramen instead.
  • Light Feminine and Dark Feminine: The dark to Eureka's light.
  • Mama Bear: Though she teases Renton in the beginning, she is willing to protect him along with Eureka, Maurice, Maeter, and Linck as if they are her own children.
  • 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.
  • Number Two: Talho is the second-in-command of Gekkostate.
  • Parenting the Husband: Discussed. She tells Eureka that she'll have to deal with both her baby and Holland's childish antics.
  • Sci-Fi Bob Haircut: After her Important Haircut.
  • Second Love: Deconstructed. She is this to Holland, which she has difficulty getting over and being the central reason for immatuirty and choice of style — to keep Holand's attention.
  • Settle for Sibling: It's implied she was in a relationship with Dewey before Holland.
  • Shipper on Deck: After going through Character Development, Talho begins to give Renton good advice on how to strengthen his relationship with Eureka.
  • Significant Wardrobe Shift: When decides to set her immaturity aside, she abandons her skimpy clothes in favor of a bodysuit.
  • 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 Womanchild attitude.
  • Womanchild: She acts and dresses like a bratty teenage girl, but in truth she's pushing 30. Part of her Character Development arc is coming to terms with this, culminating her into her "growing up" into the responsible adult of the Gekkostate becuase at the time Holland was too busy running away from it all.

  • Actual Pacifist: Only takes photographs, never fights.
  • Contemplate Our Navels: When he talks about Coralians.

    Maurice, Maeter, and Linck
Left to right: Maurice, Maeter and Linck.

Maurice is voiced by: Michiko Neya (JP), Mary Elizabeth McGlynn (EN)
Maeter is voiced by: Eriko Kigawa (JP), Peggy O'Neil (EN)
Linck is voiced by: Fumie Mizusawa (JP), Kate Higgins (EN)

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.

  • 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. That said, they're all equally annoying a lot of the time, especially early in the series.
  • Character Development: All three of them learn to respect and trust Renton, who they previously disliked.
  • 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 future adoptive mother.
  • Does Not Like Shoes: Linck is the only one of his siblings (and perhaps the only one of Gekkostate) to not wear shoes. It demonstrates his babyishness. He outgrows it in the epilogue stills of the show, where he is finally shown wearing a pair of sneakers matching his shirt color scheme at Axel's junkyard because it's unsafe to walk around without any. Maeter also used to be shoeless, as seen when Eureka first met her, but she outgrew this long ago.
  • 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.
  • Scars Are Forever: Poor Linck has a massive gash on his head from being grazed by automatic gunfire, which bled quite a lot and knocked him out cold when it was inflected. It serves as a constant harrowing reminder of what Eureka did when she was little more than a mindless puppet of Dewey Novak and what she must strive to never do again.
  • 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's boyfriend just because he wants his mama all to himself.
    • That said, he remembers being orphaned at a young age by his adoptive mother. And Eureka had just run away due to her arm breaking out in Coralian boils, setting off his attachment issues. Eureka (and Renton) respond with only love and kindness, and Maurice drops the gun while he cries in Eureka's arms.
  • 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.


Voiced by: Akio Nakamura (JP), Kirk Thornton (EN)

Pilot of the Gekkostate LFO, Terminus typeR606. Laid-back and will do anything for his partner, Hilda.

  • Big Brother Mentor: A lesser example to Renton.
  • Black and Nerdy: Often regarded as a genius by the others.
  • Chekhov's Skill: His career as a DJ and interest in music comes up a few times to help on missions: he's able to isolate parts of a song that seem off which is crucial in locating Ray Beams when she attacks the Gekko; his DJ connections helped the others locate Renton after he ran away; and he was the one playing the loud music when Gekkostate storms the planet's capitol.
  • Demoted to Extra: Hardly appears in the last few episodes.
  • Funny Afro: The only one of the crew to have an afro.
  • Innocently Insensitive: Once, he asked Renton if his mother ever taught him any manners. Too bad Renton never knew his mother... ouch. Even though Matthieu couldn't have known that, it still comes off as really damn cold.
  • Jerk with a Heart of Gold: Matthieu is insensitive (playing jokes on Renton), but he does show sympathy towards the young man in regards to Holland mistreating him.
  • Official Couple: Matthieu and Hilda often act like husband and wife, although they are clearly in a romantic relationship.
  • Token Minority

An enigmatic old man who always hangs around the Gekko.

  • Adaptation Species Change: The ending of the anime reveals he is a Coralian. In the manga, he is completely human, but is a former Sage, named Gal Kalmapa, thus allowing him to drop lots of exposition.
  • Human Alien: The ending reveals Gonzy is a Coralian.
  • Stealth Hi/Bye: He can appear behind someone — set down his carpetnote  and all — in seconds. Possibly justified by the above trope.

Voiced by: Taro Yamaguchi (JP), Tony Oliver (EN)

Second-in-command of the Gekkostate crew. One of the few people Holland confides his troubles to.

  • 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: He's never seen with his eyes open except for some very rare occurrences, revealing a pair of green eyes.
  • 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.
  • Number Two: He serves as Holland's second-in-command.

One of the more ordinary members of Gekkostate. Has a crush on Moondoggie.

  • Ambiguously Brown: She has a darker skin complexion, but her ethnicity is ambiguous.
  • 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-Partners: 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."


Voiced by: Mamoru Miyano (JP), Steve Staley (EN)

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 and becomes less of a push-around sort and starts dishing it out himself, 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.

How well does it match the trope?
