A character sheet of Gargantia on the Verdurous Planet.
A soldier of the Galactic Alliance, Ledo, is an ace Caliber pilot who, during a decisive battle between his fleet and a hostile alien race known as the Hideauze, was forced into a wormhole, stranding him in an unknown time and location. The residents of the world where Ledo now finds himself a permanent resident are not at odds with the Hideauze, forcing him to adapt to life outside of a perpetual war that has occupied his entire life.
- Adventurer Archaeologist: The ending shows that he's picked his profession as a salvager. He's in a partnership with Bevel to decipher the lost secrets of the past age and targets artifacts with historical or scientific value. He's also working on deciphering the Hideauze language and forging a relationship with them.
- Anti-Hero: He is willing to help other characters that are in danger as long as he is told to do so. However, he has been raised throughout his entire life as a Child Soldier without a moral code, and the solution to dealing with enemies is flatout killing them without showing any form of remorse, which shocked many of the Gargantian residents when he was combating the pirates. However, he gets a bit better, though.
- Badass Boast: "I fear nothing!"
- Bishōnen: The crossdressers in episode 5 are eager to recruit him into their businesses precisely because he is this.
- Blind Obedience: To the cause of killing Hideauze, or anything perceived as being them, at all costs. When a huge pod of whalesquid passes under the fleet, Ridget is forced to hold him at gunpoint so that he doesn't attack them and make them angry — which he very much wants to do, despite the fact that doing so might have put the fleet at risk. Later subverted when he makes it clear that part of the reason he wants to destroy the whale-squid is that he's worried that they might force the humans on Earth into a similar situation to the one the Alliance is in.
- Broken Pedestal: Kugel becomes one to him at the end of the series. When he was serving in the Galactic Alliance, Ledo had high regard for Kugel. However, he ends up losing Kugel's trust when he realizes that his cult intends to destroy Gargantia and that Kugel is Dead All Along.
- Character Development: Although he still does some really stupid things while at Gargantia, spending a lot of months in a peaceful civilization allows Ledo to gradually transform from a emotionless Child Soldier, whose only goal in his life to defeat the Hideauze, to a young boy who developed some form of moral conscience. Compare his totally emotionless response when a boy was sent to be burnt to death for deficiency in a flashback to episode 9 where he reacted in sadness and angst when he finds out that the Hideauze are actually genetically modified humans and Chamber killing a baby Hideauze without his command.
- Character Tic: He's constantly carving peculiar ocarinas. Given that he doesn't seem to know what they are, it's almost certainly an instinctive habit. He picked it up from a kid he used to know who showed it to him right before he was sent to be incinerated for deficiency.
- Chekhov's Gun: It's implied that the ocarina can calm down the Hideauze.
- Child Soldier: To the extreme. Not only is he an experienced soldier at 16, it's the only life he knows, and it's the only life he was raised to understand. The only other mode of life he is aware of is to stand by and await further orders.
- Dangerous Forbidden Technique: By "merging" with Chamber, he can enhance their abilities at the cost of essentially burning out his own body. In the final episode, Chamber is extremely reluctant to have him go through with it and eventually kicks him out of the cockpit so he can survive.
- Desperately Looking for a Purpose in Life: Episode 5 has him wondering what kind of job he can take in Gargantia. He doesn't seem to fit in either fishing, farming, ranching, or salvaging. The episode ends without him figuring out his place in the fleet. He finally decides to be part of the Salvage Teams in Episode 6. Episode 7 has his purpose in life come looking for him: to be a soldier.
- Determinator: At one point, Pinion sends him on a mysterious errand that takes him through Gargantia's red-light district. His first time through, he is harassed by several transvestites who comically attempt to force him to become one of them, freaking Ledo out severely, as might be expected, and ending with him being chased up and falling out of a high tower. Ledo later braves the area twice more in order to finish the job.
- Fish out of Water: He's a bit squicked out when Chamber tells him that he's been offered carcasses (i.e. fish jerky) to eat. He also has no clue about balance between factions on Earth. Judging from what we've seen of the Alliance, it's unlikely he knows much of anything beyond being a soldier.
- Going Native: At the end of the series, he settles down on Gargantia and becomes a salvager.
- Heel Realization: Holy cow, does he ever in Episode 9. See Heroic BSoD below for more details.
- Heroic Albino: He has white hair, pale skin, and is the main protagonist.
- Heroic BSoD: He has a massive one in Episode 9 upon discovering that the Hideauze were a faction of humans who responded to earth's devolving climate by genetically modifying themselves to be able to survive in extreme environments, and the Galactic Alliance originated as those who opposed this measure and just wanted to abandon earth in its entirety. Still don't think it was big? He tries to stop Chamber from killing a Hideauze.
- Heroic Sacrifice: Averted. At the climax of his battle against Striker, Ledo resolves to use Chamber at full power, which would result in his organ systems shutting down and dying. After Ledo tells Chamber his reasons for choosing to sacrifice himself, Chamber uses a Caliber protocol to declare Ledo "unfit" as a soldier and detaches the cockpit. Ledo can only look on as Chamber instead sacrifices himself to stop Striker, and is left in tears when the latter's wreckage falls into the ocean.
- I Choose to Stay: Not that he has much choice, but after everything he's been through and has learned, Ledo ultimately accepts life on Gargantia and chooses to live peacefully as a savager, although, a girl like Amy would be more than enough of a reason for him to stay.
- In-Series Nickname: Melty always refers to him as "the hottie" (ikemen) and never by name.
- Instant Expert: Averted. He attempts to control a Yunboro instead of Chamber in episode six. While he does get a hold of the very basic controls, he overestimated the technology within it.note Also, since he doesn't know how to swim, he had no idea how to get the Yumboro to do the same and wound up having to get fished out by some crew members on the Gargantia.
- Language Barrier: In early episodes he relies on Chamber for translations, and wears a small headset for that purpose. But by episode 4 he's able to string together simple sentences on his own, and his mastery of the language continues to grow so that by the final episodes he no longer needs to depend on Chamber. Definitely Symbolic.
- Meaningful Name: "Ledo" may be derived from Leto, the Greek titaness, whose own name may derive from the Greek word lethos ("hidden, or forgotten"). In order to give birth, Leto fled to Delos, a far-distant island with no attachment to the Earth.
- Mr. Fanservice: A handsome young dude with a rockin' bod. Saaya and Melty refer to him as "the hottie".
- Murder Is the Best Solution: His personal philosophy. It's a given where he hails from, but here on Earth, it brings about serious consequences. As a result of Ledo using this option, he causes problems for the Gargantia fleet; first against human pirates, and later when he kills a whale squid, which Chamber identifies as Hideauze, a large swarm of them pass by Gargantia, and Ledo is held at gunpoint to make sure he doesn't bring about any further hostilities from the whale squids by Ridget.
- My God, What Have I Done?: His reaction when he finds out that the Hideauze are genetically altered humans.
- Mystical White Hair: Courtesy of his otherworldy origins.
- No Social Skills: As a result of pretty much being raised for and experiencing nothing but war and battle, he knows little to no social cues.
- Not So Stoic: His stoicism cracks when confronted to manure or a horde of cabaret transvestites.
- Pragmatic Hero: He kidnaps Amy so that he won't be attacked on sight but is willing to open negotiations later. He carefully questions what are seemingly contradictions in Bellows' words about the way of life on Earth. He's aiding the Gargantians simply because they have the kind of norms that may facilitate his return to his fleet. He's not necessarily viewing Gargantians as good people — he probably doesn't think about the bargain much beyond, "Don't do things that reduce your chance of survival."
- Purple Eyes: He and the other soldiers of the Alliance are implied to be Designer Babies. He is also the most powerful human on Earth.
- Rei Ayanami Expy: A male case, but he fits the bill. White hair, pale skin, purple eyes, otherworldly origins, No Social Skills, stoic and even a mecha pilot to boot.
- Shell-Shocked Veteran: When he sees the whole-cooked octopus in the "super special" dinner during episode 6, he immediately draws his gun — its tentacles remind him of Hideauze. He has to be talked out of his combat stance. The awful thing is that he is right of his suspicion: the Hideauze do originate from Earth, though not as hideous space krakens.
- Spell My Name with an "S": Is it "Ledo" or "Red?" Ledo, if you decipher the Fictionary. The supplementary light novel also uses Ledo.
- The Stoic: In a soldierly way. He's always calm and pragmatic in the face of obstacles.
- Straw Vulcan: It seems that he exists solely to prove that Gargantians are right, though the series arguably turns him into a subversion; he ultimately has, or at least gains, a much clearer picture of the situation than the rest of the Gargantians, and it makes the Gargantian choice of lifestyle correspondingly more difficult for him to agree with. Through a lot of Character Development, he and Chamber come to their own conclusions that lead Ledo to stick with Gargantia. The ending shows that he hasn't completely accepted the status quo; he actively researches Earth's past, associates with the whalesquid, and reports his findings with Bevel in order to dispel Gargantia's intellectual stagnation. So while it seems that he spends a lot of the early parts of the series needing to be educated on the error of his ways, it ultimately turns out that the tables do, in fact, turn.
- Tender Tears: When remembering his figurative little brother, who taught him how to carve a flute.
- The Load: A large part of his personal conflict is that he has no useful skills of his own with which he can support himself. He's given living quarters as a stipend, and his cost of living is low enough that loaning out Chamber for manual labor gets him by, but he's looked down upon with pity or mild contempt because he doesn't contribute to a society in which you need to find a place for yourself or you burden the community.
- Trapped in Another World: He gets trapped in the real Earth after going through a time portal.
- Troubled, but Cute: How the Gargantian girls see him.
- Tyke Bomb: He was raised to be a fighter since he was young.
- Turned Against Their Masters: Ledo doesn't agree with Kugel's plan to destroy Gargantia to make an example of them to other fleets, particularly after learning the truth about the Hideauze.
- What You Are in the Dark: When the belief that the Hideauze weren't monsters and Ledo's instilled philosophy to kill them finally have equal justification, Ledo, without guidance or witnesses, refuses to kill the Hideauze.
The AI system of Ledo's Caliber. He progressively deciphers the earthlings' language and acts as a translator for Ledo until he begins to grasp the language himself. Chamber can perform simple tasks on his own when given a basic goal and can follow the orders of a third party with Ledo's permission. Despite being a machine, Chamber displays a good amount of independence and even a personality.
- Anti-Gravity: One of his many capabilities.
- Artificial Intelligence: Uniquely so— absolutely no other Humongous Mecha on Earth has an A.I. Except Striker.
- Beam Spam: Chamber is able to destroy dozens of targets with a single barrage, which, unfortunately, causes a lot of trouble for the people of Gargantia. What's even more problematic is the fact that he seems to have only one setting: Annihilate. (Humorously, he can't even use this power to barbecue meat without incinerating it.)
- Benevolent A.I.: Whereas so many AI similar to him throughout all forms of media, Stryker amongst them, come to conclusions fueled by Blue and Orange Morality at best and downright evil ones at worst, Chamber's conclusions are always sympathetic, but reached using pure logic. He implies that this is due to the fact that Ledo is his operator.
- Blessed with Suck: Despite being armed with incredibly powerful weapons and the ability to fly, Chamber's assets are actually liabilities on the Gargantia. The anti-gravity field will lift other objects nearby uncontrollably, and his beam weapons are set to destroy their targets. As a result, Chamber has been reduced to being a forklift and a makeshift barbecue grill. The only time he is able to use these powers with fine control is when Ledo is at the helm.
- Butt-Monkey: He keeps getting into situations in which he's awkward.
- The Comically Serious: During episode 5 and Petit Gargantia shorts.
- Covert Pervert: In episode 6 of Petit, Amy asks him why he has detailed photos of the girls in their Belly Dancer outfits. He awkwardly states his purpose as a Caliber while slowly retreating.
- Deadpan Snarker: "I will leave it to your decision," with regards to whether to accept the dried fish Amy offers when Ledo is squicked out by the idea of consuming animal carcasses.
- Disney Death: May or may not be true depending on whether we'll get a true sequel that brings back an actual need for him, or possibilities to develop his character in some other capacity now that Ledo no longer is reliant on him. While Striker was blown to bits, Chamber is shown surprisingly intact on the ocean floor in The Stinger... and Ragnarök Proofing of ocean salvage is very much in effect in this series. Not to mention the whalesquids seem to have an interest in him.
- Fantastic Racism: After Ledo learns the Hideauze were originally human, Chamber still claims that they need to be destroyed. He then explains that this is not a result of his programming, but by his own reasoning. To him, the Hideauze have abandoned civilization and cannot be considered human anymore. He believes that it is simply impossible for humans and Hideauze to co-exist. His reasoning is also part of why he eventually opposes Striker, as her beliefs and desire for humans to stop thinking for themselves and obey her goes against his belief of what a human is.
- Heroic Sacrifice: After ejecting Ledo and the cockpit, Chamber takes Striker down with him with by grappling and destroying her with an energy blast at point-blank range.
- In-Series Nickname: Pinion refers to him as the "tin can," and that nickname is occasionally used in the fandom as well.
- Loophole Abuse: In the last episode, he "decides" that Ledo is psychologically unfit to be a soldier and ejects him from the cockpit, allowing Chamber to preform a Heroic Sacrifice.
- Meaningful Name: Chamber, as in a room or set of rooms, as well as an enclosed space.
- Mook Mobile: His designated role. It gets subverted heavily.
- Mundane Utility: As forklift. Though the Gargantians ban him from using anti-gravity to move crates around. Because he sucks at it. In the next episode, he gets tricked into being used to barbecue meat on his body. Initially, Pinion tried to use his Beam Spam to microwave the meat, but it was too intense, and the meat got ruined.
- Normal Fish in a Tiny Pond: From what we see of the Machine Calibers, Chamber isn't anything special as far as the Galactic Alliance is concerned, just one among thousands of mass-produced combat vehicles of similar ability. On Earth, however, he's so much more advanced than everything else he's pretty much unstoppable, to the point that he wiped out an entire pirate attack force in mere seconds, while leaving all their hostages unharmed.
- Precision F-Strike: His Famous Last Words as he is about to blow himself and Striker up.Chamber: Response to final warning: Go to hell, tin can!
- Robot Buddy: He's basically the third protagonist of this anime, after Ledo and Amy.
- Sesquipedalian Loquaciousness: He translates Amy's Cluster F-Bomb as "reproduction with one's mother, as well as sanctified excrement."
- Translator Microbes: One of his many functions. An interesting note is that he had no knowledge of Earth's language beforehand, and had to "pick it up" (so to speak) by recoding all the jabber from the natives for a while before he could start translating.
- Undying Loyalty: He will electrocute anyone, aside from Ledo, who steps into his cockpit. This is a unique variant, as it's likely a result of his programming. At the end of the series, it's all but stated that he really is that loyal to Ledo.Chamber: I exist solely to set you up for success.
- Unskilled, but Strong: He's unquestionably the most powerful sentient being on Earth (so far), but he's largely unable to finely control his own abilities, because in the Alliance, that's what the pilots are for, probably as a safety measure against the Robot War.
- Verbal Tic: Statement: Much like HK-47, Chamber adds descriptive nouns to the start of his sentences.
Ledo's commanding officer seen in the first episode, where he commits Heroic Sacrifice to save as many of his men as possible, including Ledo. He's believed to have been killed in the opening battle, but is eventually revealed to have crashed on Earth and joined a fleet similarly to Ledo. However, things on his fleet went very differently...
- A Father to His Men: Is this at the start of the series, as well as much of the second OVA. And then, Linaria dies, and it keeps on getting worse from there... It's actually a bit of a subversion with Ledo, as seen under Combat Pragmatist.
- A God Am I: To an extent. He resists this trope at first and considers his role as a divine emissary to be a farce, but after crossing the Despair Event Horizon, he starts calling himself a god.
- Asskicking Equals Authority: On Earth, he leads a cult due to his ability to wipe out the whale squids that humans there seem deathly afraid of. The second OVA episode reveals that the cult was originally a pirate fleet that worshipped the Hideauze as gods.
- Blood from the Mouth: He suffers from this too shortly after Linaria, the girl he saved in the second OVA, dies from a similar disease, most likely tuberculosis.
- Chekhov's Gunman: Seemed like a throwaway sacrifice in the first episode. Turns out to have landed on Earth and becomes a foil to Ledo. Double subverted when it turns out that he's been deceased for quite some time.
- Combat Pragmatist: He chooses to stay behind and let Ledo live to fight another day, not as a simple act of selflessness, but because Ledo is younger and will be able to do more for the Alliance in the grand scheme of things.
- Dead All Along: Although, the second OVA shows what he did before he died.
- Despair Event Horizon: He crosses it when Linaria dies. The fact that her father's fleet expects him to serve as an emissary to the "God of the Sky" overwhelms him when he can't even save a single girl.
- Disney Death: Downplayed, he survives but still dies before he could meet Ledo.
- Evil Counterpart: Played with until The Reveal. Eventually played straight in the second OVA.
- The Faceless: Owing to what he calls an endemic disease that requires him to remain in his sterilized cockpit, he has become this to his allies — Striker does a fair bit of the talking for him, and Ledo only sees him through transmissions or as a hologram. Chamber concludes that he is also deliberately remaining unseen so as to inspire awe and fear in his followers. As it turns out, there's a reason for this.
- FaceHeel Turn: He was a well-known commander of the Galactic Alliance, but Linaria's death causes him to have his cult wipe out the whale squids by the time the story begins.
- Fallen Hero: In the second OVA, it's revealed that he genuinely wanted to help the people in his fleet, and he explicitly rejected the culling policies of the Alliance while on Earth. Then, his Love Interest died...
- I Let Gwen Stacy Die: Linaria's death greatly affects him. He's supposed to be an Emissary of God, and yet he can't save even this one girl.
- Incurable Cough of Death: He suffers one by the end of the second OVA. It's suggested he caught Linaria's disease.
- Love Makes You Crazy: Let's just say losing Linaria to an illness did not help his sanity one bit.
- Meaningful Name: Kugel is a Jewish baked pudding or casserole. It's also German for "bullet".
- Mentor Occupational Hazard: Double Subverted. He survives, but dies later off-screen.
- Not Quite Dead: Or so we thought until he's shown to be Deader Than Dead, with his body rapidly decomposing, complete with his head falling off once exposed to the elements.
- Not So Different: To Ledo, if the second OVA is anything to go by.
- Pet the Dog: He actually adopts Linaria's squirrel after her death.
- Posthumous Character: Of sorts. While he actually didn't die in "Capitivity", it's still the last time he's seen alive in the series. The second OVA explains what happened between his apparent death and his actual death.
- Reasonable Authority Figure: He tells Ledo to escape while he holds back the Hideauze in the first episode, because Ledo is younger and can still kill more Hideauze than he could. He initially tries to be this in the second OVA, but after Linaria dies, along with coughing up blood, and Striker's influence, he figures he might as well lead them the way they wanted him to.
- Religion of Evil: Before dying and leaving everything to Striker, he founded one based off of the Galactic Alliance's philosophies, complete with "sacrifices" note of weaker fleet members, scarily akin to how deficient soldiers in the Alliance were incinerated. The second OVA reveals that Kugel was horrified of seeing Gargantians worship Hideauze and wanted to lead them out of danger. The formation of the cult, however, was Striker's idea, taking advantage of Kugel's grief from losing Linaria and his horror of seeing people worship Hideauze.
- Sanity Slippage: A one-two punch of losing Linaria and Striker's manipulation takes a massive toll on his sanity.
- Small Role, Big Impact: He spends less than a minute on screen and has about three lines, but he's the main reason Ledo even winds up on the Gargantia to begin with. Later subverted when he turns up on Earth and has a larger role in the story. Flat-out averted in the second OVA. He's the main character, and you really get to understand why he and Striker are what they are by the time they are mentioned again in the first season.
- Tragic Villain: Becomes this by the end of the second OVA.
- Villain Episode: The second OVA covers his time on Earth, and what he runs into. One has to wonder how he would have acted had he found Gargantia's fleet instead of the pirate one.
- Visionary Villain: After Linaria's death, he begins channeling the God-Emperor of Mankind: that humans shall be united and strong under his watchful eyes. On the other hand, it's not clear how much of it is his own vision and how much of it is actually Striker's influence.
- Well-Intentioned Extremist: He wanted to save human lives on Earth, but due a lack of medical supplies and medical knowledge, he is unable to save even one girl from dying from disease. Striker also tells him that a lot of people are sick, and are carrying communicable diseases, which also eventually does him in, hence one reason why the cult carries out the ritual sacrifices of getting rid of unhealthy humans. While this is no doubt an extreme measure, Striker figured culling the sick humans would allow the healthy ones to survive, rather than also get sick and die. Since Kugel was also coughing up blood by the end of the second OVA, it's probably understandable from his viewpoint that he had to do this to ensure the fleet survives.
The AI system in Kugel's Caliber.
- Ace Custom: As a Machine Caliber assigned to a commander, her combat performance is slightly higher than the standard for a unit her same type. Which is why Ledo and Chamber end up having a rather difficult time when fighting her.
- A God Am I: She begins to think in this way after Kugel dies, reasoning that her practices, such as getting rid of weaker humans, is standard Galactic Alliance protocol. She then reasons that by becoming a god, she is relieving the burden of having to think of humans. Chamber calls her out on this.
- A.I. Is a Crapshoot: Played with. She is doing exactly what she was programmed to do and is following both the Alliance's and Kugel's ideals. However, Chamber then claims that she is acting illogically and that her A God Am I beliefs are the result of a flaw in her programming — namely that Kugel's actions and poor choices influenced her own conclusions.
- The Corrupter: You can thank her for driving Kugel's Sanity Slippage and for starting his cult.
- Cyber Cyclops: Unlike Chamber, her face is strictly ornamental, with a single real eye built into her neck.
- Distaff Counterpart: In many ways, Striker is a female version of Chamber, voice being amongst them.
- Evil Cannot Comprehend Good: She has no idea why Ledo and Chamber would oppose her ways, as she sees them as an extension of the Galactic Alliance's ways and amounting to allowing the humans of earth to advance and return to their former glory.
- Evil Counterpart: Turns out to be this to Chamber.
- Manipulative Bitch: If the second OVA is anything to go by.
- Meaningful Name: Striker, as in someone or something that hits someone or something else.
- Metaphorically True: When Striker-as-Kugel state that an endemic disease got the better of him, she was telling the truth. What she neglected to tell was that the same disease also claimed his life before Ledo met them, and that she was not just restricting him to the cockpit as she made it out to be.
- Purple Is Powerful: She has a purple and white paint job.
- Resistance Is Futile: Says this when Ledo discovers that Kugel is dead.
- Well-Intentioned Extremist: What she claims to be, but is, in reality, driven to dominate humans, have them perform human sacrifices to appease her, and reestablish a Galactic Alliance on Earth. In the end, Chamber calls her out on what she really is and declares her as needing to be exterminated.
- Beast with a Human Face: Though only their teeth can be seen in most encounters, however the Hideauze still have a humanoid form in their younger stages of life. In addition when their is a flashback of Ledo and Chamber's massacre of the Hideauze nest in Episode 10 that occurred in the prior episode, one of them had their vaguely head looking head fully out of its body mass. Justified as they are part Human.
- Bilingual Bonus: The name of the Hideauze rather interestingly also sounds like an alteration of the English word "Hideous". Which is most likely because it is a name given to them by the leadership of the Galactic Alliance who disapproved of them crossing the Moral Event Horizon by "Casting away their Humanity" to turn themselves into such monstrosities.
- Combat Tentacles: The Hideauze' most prominent attacks. The mechas that seem to be invincible on Earth can be easily crushed by them.
- Evilutionary Biologist: The Evolvers were condemned by many people in the antediluvian period for practicing unethical and illegal experiments to create beings that could survive in harsher environments. For bonus points, one protester in one of the archival news videos that Ledo sees even calls the Evolvers "Evilutionists".
- Irony: The Evolvers were some of the most highly intelligent Biological scientists, but in the present are now extremely primitive beings who have possibly lost their Sapience as a result of no longer having any sort of challenge to overcome.
- A Nazi by Any Other Name: Though the Galactic Alliance has some unsettling similarities with them, but the Hideauze also resemble this trope, what with their desire to wipe out the inferior and simple-minded humans who failed to embrace a genetic adjustment program.
- Organic Technology: Apparently used by the Hideauze.
- Playing with Syringes: The Evolvers performed unethical experiments including on some of their own children with the intention of being able to survive even in the vacuum of space and other inhospitable environments without the assistance of technology.
- Professor Guinea Pig: The leaders of the Evolvers also turned themselves into Hideauze.
- The Sociopath: Many of the Evolvers seem to have this mindset as from what little information as there is of them prior to "devolving" into the Hideauze of the present suggests that they were hedonists who were more interested in prolonging their own lives than in any sort of interest in the common good of humanity.
- Straw Nihilist: Chamber certainly believes the Evolvers to be this based on the aforementioned details.
- Tentacled Terror: The Hideauze are aggressive squid-like monsters engaged in a long war against the Galactic Alliance of Humankind. They are also the descendants of humans who genetically altered themselves to survive in the vacuum of space.
- Ultimate Lifeform: Name-dropped by Ledo when after learning that the Hideauze are the descendants of Humans who performed biological engineering on themselves in order to survive any and all environments. Chamber does not believe the Hideauze to be invincible as the Evolver propaganda on the archival videos that Ledo watched claims them to be as by making themselves more physically durable, they no longer encountered any sort of challenge and thus gradually lost their intelligence over the years, thus sacrificing their ability to perform critical thinking necessary to overcome limitations.
- Was Once a Man: The Hideauze are the Half-Human Hybrid descendants of the Evolvers.
A courier of the Gargantian fleet, Amy is the first to come in contact with Ledo after his Caliber was winched from the ocean floor. It was through her mediation with Ledo and testimony to the higher officials of Gargantia that gave them a reason to trust him and offer him sanctuary. She acts as Ledo's guide in adapting to life on Gargantia and helps him learn about normal life. She eventually falls in love with him.
- A-Cup Angst: In Petit Gargantia, she gets angry and kicks Chamber after he calls her bust the second smallest of the cast.
- Belly Dancer: A pretty damn good one, too; Ledo even asks her to dance for him again the night after she first performed, and this is someone who's NEVER experienced sexual arousal or romantic attraction in his life! Amy is definitely having an effect on Ledo in more ways than one.
- Big Damn Heroes:
- Charles Atlas Superpower: At one point, while gliding on her glider, she grabs a rope hanging from a tall pole by hand and uses it to slingshot herself around. Considering she's going maybe 20-30 mph, with the full weight of Ledo and the glider on her arm, she'd be lucky to keep it attached.
- Cool Big Sis: To Bevel.
- Courier: What her job is on the Gargantia. It's an important job on such a big ship and one of the reasons why she has so many friends in high places.
- Dangerously Short Skirt: Well, she might not be a fighter type, but she is very physically active and flies a hang-glider in such a way that Panty Shots are inevitable.
- First Girl Wins: With Ledo, not that there's really much competition.
- The Heart: Always does her best to convince people to give peace a chance. When she tries it with Ledo, it ironically doesn't work — Ledo has to be held at gunpoint. This anime is not by Studio Ghibli.
- Improbable Piloting Skills: She pulls off some absolutely amazing flight tricks on her glider, including catching falling friends and slingshotting her way to victory when she raced her gal pals.
- Manic Pixie Dream Girl: To Ledo. Although, arguably, a subversion: she's the steady-minded working girl trying to help the loner settle down. A stabilizing influence, if you will. She's just also enthusiastic and creative, and can get Ledo anywhere.
- Ms. Fanservice: Especially in episodes 5 and 6, where she wears a swimsuit and a belly-dancer uniform.
- Nice Girl: She tries to convince people on the Gargantian fleet to help Ledo and continually assists him in trying to adjust to barge life.
- Screw the Rules, I Have Connections!: Knowing the inner council of Gargantia in person gives her and her friends a lot of leeway. The girls don't get in trouble when they stow away aboard salvage party's ship in OVA 1 and it's Amy barging into the meeting and begging that the Gargantia help Ledo fight the cultist that leads to using The Stairway to Heaven.
- What the Hell, Hero?: She calls Ledo out for disintegrating the pirates that were attacking Gargantia at the beginning of episode 3.
Gargantia's second-in-command, a cool and aloof young woman who takes her responsibilities very seriously.
- Girlish Pigtails: When she was younger.
- Letting Her Hair Down: After becoming the commander of the remnants of the Gargantian fleet and finding the resolve necessary to take that position.
- Love Triangle: Episode 14, a bonus episode made for the home release, established that she was in one when she was younger. She lost, but it was pretty amicable on all sides.
- Number Two: To Commodore Fairlock, partially due to him being an old friend of her father. When Fairlock dies, she becomes Number One.
- Reasonable Authority Figure: She's skeptical of Ledo but believes him when he explains his motives for negotiation with Gargantia. Unfortunately, what passes for reasonable to her is seen by others as weakness.
- Stripperiffic: In episode five, she wears just about the skimpiest bathing suit of them all.
- You Gotta Have Blue Hair: Purple in her case.
- You Are in Command Now: Following Commodore Fairlock's death, she is given the command of the entirety of Gargantia. Deconstructed, though: she doesn't have enough political muscle nor experience due to her young age, and Gargantians loyal to Flange decides to break apart from the fleet.
Amy's little brother, a smart and inquisitive, but frail-bodied boy, who is very interested in how the world around them works. Seems to have a knack for the technical side of things and is always seen crafting some models of gadgets.
- Adorably Precocious Child: He really means it with his preaching to Ledo about how people need each other.
- Child Prodigy: Shows intelligence and understanding apparently beyond others, such as creating a primitive automatic fan.
- Ill Boy: Often seen bedridden or in a wheelchair.
- The Heart: To Ledo. Mainly because Bevel reminds him of his figurative little brother, who is dead.
- Meaningful Name: Bebel is a German surname.
- Spell My Name with an "S": "Bebel" seems to be the official romanization, but going with the Theme Naming scheme common on Gargantia, it's obviously intended to be "Bevel."
- Wise Beyond Their Years: He contemplates space and the legend about people who come back from there in a manner seldom seen in children his age. He is seen, in episode 13, teaching a bunch of people about the things he's learned from Dr. Oldham.
- Ambiguously Brown: She has dark-colored skin.
- Cool Big Sis: Seems to be one for Amy.
- Dark-Skinned Redhead: She has dark skin and red hair.
- Disaster Scavengers: Her job.
- Expy: She resembles Nadie from El Cazador de la Bruja.
- Meaningful Name: Bellows, as in a device for pushing pressurized air in a controlled quantity to a controlled location such as air through an oxygen tank.
- Ms. Exposition: It is her who initially teaches Ledo about Earth's customs and workings.
- Ms. Fanservice: While she doesn't flaunt it around blatantly, her outfit and figure are very revealing.
- Wrench Wench: Is rather good around machinery and is the fleet's main salvager.
- Best Served Cold: He lost his brother long ago, and only recently has he put a plan into action upon seeing Chamber and Ledo being able to take out a Whalesquid.
- Big Brother Instinct: He grabs the biggest wrench he has and quickly tells Amy to get away, when he realizes that someone's come out of the mecha that they excavated. And in episode 13, he also orders his workers off the ship when he discovers their weapons have too long of a cooldown period between shots to be of much more use.
- Butt-Monkey: A mild example. The gags he's fallen victim to so far include:
- Hopping around like a fool when dodging Ledo's Ray Gun.
- Getting electrocuted by Chamber when he falls into the cockpit.
- Having a bunch of people crashing his barbecue in episode 5.
- Getting chewed out by his coworkers for taking the day off for said barbecue.
- Failing to recruit Ledo (and by extension, Chamber) to his Salvage Team, despite having treated him to a rowdy bar.
- After his over-the-air declaration of sovereignty due to their recently acquired lost tech, Kugel's fleet shows up and outclasses them. Pinion, himself, realizes whatever respect he had built up as being a leader in the splinter fleet is gone at the time and willingly submits to be the envoy to discuss terms with Kugel's fleet before it was announced they had asked for him by name.
- Defeat Means Friendship: A particularly sinister example. In a manner befitting barbarian overlords, he spares the fleets he defeats because he wants to build an empire based on his military might.
- Disaster Scavengers: His steady job is a mechanic, though he may take to scavenging from time to time.
- Drunk on the Dark Side: He's significantly less humane after he has a railgun and other assortments of pre-ice age weaponry. Then, Kugel's forces perform the "Sacrifice ritual," and that breaks him out of it.
- Enemy Mine: Despite being at different odds with Lukkage, he's willing to work together with her when it comes down to Kugel's fleet, since Kugel decided to invade Gargantia.
- Expository Hairstyle Change: His pompadour is undone when he decides to join Lukkage in her rebellion.
- Expy: He bears somewhat of a resemblance to to Groose.
- From Nobody to Nightmare: Used to be a mechanic and the resident Jerk with a Heart of Gold in Gargantia. After he gets ahold of pre-ice age weaponry, however, his ego explodes, and he all but challenges the entire world, claiming that due to the technology and weapons, they are the rulers of the seas. He gets better after seeing Kugel's fleet show up and assimilate his own men by force, as well as having viewed the "Sacrifice ritual."
- Going Down with the Ship: When it becomes apparent that his lost tech wouldn't be able to reload fast enough to be a contributing factor, he calls all his workers useless and kicks them off his ship, intending to sacrifice himself to make sure no one gets the "Treasure Castle" he claims for himself and his brother. He is only saved at the last moment by Lukkage.
- Heel Realization: He starts to have second thoughts of joining Kugel's fleet at the beginning of episode 12.
- Heroic Sacrifice: Attempted during the finale of the series, but it doesn't work out.
- Hidden Depths: He might seem like a goofy guy, but he lost his older brother to the Hideauze and will go to great lengths to get his revenge. And with Ledo as an ally, he finally gets his opportunity, even if he must lie to his fellow Gargantians to get them to go with his plan.
- Jerk with a Heart of Gold: He frequently makes fun of Ledo for being useless and/or an outsider, but he throws a party for Ledo as a way to cheer him up after his fruitless job search in episode 5. In the next episode, he treats him to a nice dinner before offering him a job. On a more serious level, he commits a lot of unsavory acts in order to obtain treasure, and even Lukkage is disturbed by how easily he sells out. However, once he learns about the atrocities the Kugel fleet is committing, he does end up choosing to protect his friends over the promise of wealth.
- Jumping Off the Slippery Slope: After he find a cache of pre-ice age technology, which includes a railgun, he decides to begin acting as if he should be the king of the world— to hell with bettering humanity or making peace.
- Meaningful Name: Pinion is the joint of a bird's wing or any of the outermost primary feathers of the wing. It's also the smallest gear in a gear drive train.
- Opt Out: He leaves Kugel's fleet after learning of how monstrous the latter's actions were.
- Pointy-Haired Boss: He immediately lets his newfound power go to his head after recovering the old-world weaponry. He's got neither the skills nor the temperament necessary for a command role.
- Rage Against the Heavens: A variation on this. The whalesquids are considered sacred animals by the inhabitants of the present day and that killing them will bring about divine retribution. Unlike the other members of Gargantia, Pinion has only antipathy for them for killing his brother in a past salvaging run they were on while he could do nothing to save him.
- Screw This, I'm Outta Here!: He decides to bail out of Kugel's fleet once he realizes the monstrosities of his plans.
- Secret Test: In episode 11, he is requested over at Kugel's fleet and put in a large room with no one there. He sees something on the table, gets a little curious about it, and eventually manages to open it. Turns out that Striker had put that device there to see if he had the minimum skills required to fix and reactivate the weapons recovered throughout the ocean floor over the years.
- Belly Dancer: While not as good a dancer as Amy, the show focuses quite a bit on her butt.
- Buxom Is Better: She has biggest breast of three female teens so far.
- The Ingenue: Overall pretty pure, yet not above a little Female Gaze (regarding Ledo's muscles/looks), nor pulling a little trick on Ledo/Amy in the first OVA. Also in Petit Gargantia, when Ledo asks her and Melty what "let's shag" means (regarding the cross-dressers chasing him), Melty seems to think it means getting along and says as much, whereas Saaya's thought bubbles show a censored version of what it actually means, but she chooses not to burst their bubbles.
- Hair Decorations: Wears a hairclip at the end of her hair.
- Nice Girl: Tries very hard to cheer Amy up when she's down.
- Shipper on Deck: Not quite as overt about it as Melty, but clearly she's all for Amy's closeness with Ledo, even when they're both admiring them themselves.
- All Up to You: Basically what Ledo tells her when asking her to deliver a warning to Gargantia.
- Belly Dancer: Not as good as Amy, but we get a very good look at her hips.
- But Now I Must Go: Flange is her grandfather. When he decides to separate from the Gargantian Fleet, Melty chooses to accompany him, as he is her only (shown) living relative. Later when Flange rejoins the Gargantian fleet, she also returns.
- Determinator: Delivers a warning about the impending attack on Gargantia via a craft that's only meant for short-range trips. The effort nearly kills her when she collapses mid-flight, but she winds up successfully delivering the message.
- The Gadfly: Seems to enjoy teasing people all around.
- Girlish Pigtails: She ties her hair into twin tails using ribbons.
- Hair Decorations: She has ribbons on her twin tails.
- Meaningful Name: Melty means having a high tendency to melt.
- Shipper on Deck: Enjoys teasing Amy about her closeness with Ledo.
- The Tease: Enjoys ogling and flirting with Ledo herself, nonetheless.
- A Father to His Men: By his own admission, the only thing that validates his existence is the smile of the Gargantians. Seeing his fleet facing one crisis after another which eventually cause them to split politically is what gives him the heart attack.
- Hollywood Heart Attack: He experiences cardiac arrest when he sees his fleet become politically divided, adding yet another layer to the existing crisis.
- Reasonable Authority Figure: When Gargantia first encounters Ledo and Chamber, many of the people want to shoot Ledo and take Chamber apart to research it. However, Fairlock tells them that doing that would be a really bad idea, since if they did attack, whoever the two are affiliated with may retaliate, so he tells them to hold off for now until they know more about the two.
A woman pirate who's become famous for her powerful custom Yumboro.
- Absolute Cleavage: Just look at the picture!
- Ace Custom: Her lobster-like Yumboro. Though it's still no match against Chamber, she is quite formidable against the other Yunoboroids.
- Asskicking Equals Authority: She's the fiercest fighter amongst all of the pirates, as seen in episodes 3 and 12.
- Blood Knight: Is quite eager to spill blood in episode 3 after Ledo kills some of her crew. And is still quite eager to fight in episode 12.
- Chromatic Superiority: Her mech is red and more powerful than most Earth mechs. The alien and black Chamber is still the top dog, though.
- Curb-Stomp Battle:
- Despite the fact that her Lobster mech and her two subordinates in speedboats usually have the advantage in battle, they're no more effective against Chamber than a real lobster and two fishes on hooks. The end result was the Lobster mech being torn apart and tossed back into the ocean with the two boats, like a kind of mecha catch-and-release.
- Episode 12 shows her more than holding her own against Kugel's cultists in their Yumboros. Thankfully Ledo is there to keep the Striker unit busy, unlike when she first attacked Gargantia and had to deal with Chamber.
- Dark Action Girl: While she may be severely Overshadowed by Awesome, single best Humongous Mecha pilot in the show who isn't using Alliance tech, and a terror to the floating cities of her flooded world.
- Dominatrix: She has two sex slaves chained to her throne. Oddly enough for a pirate queen, all later signs indicate that she's actually the conventional kind of dominatrix, and this is just consensual BDSM play with trusted subordinates rather than anything nastier.
- Even Evil Has Standards: Had plans to betray them before by hiding some of her crew, but after seeing just how batshit insane the cultists who worship Kugel are, she begins to initiate her plan for a coup.
- Everything Is Better With Spinning: One of her Yumboro's main modes of attack when on land is to start spinning around and knock over enemy yumboros.
- Gag Boobs: She has the largest boobs in the series.
- Gratuitous Italian: Yells out "PINION AMORE!!" in the final episode.
- Green Rooming: She is introduced in episode 3, attacking the Gargantia fleet in retaliation for Ledo killing her men in the previous episode. Afterward she doesn't show up again until episode 11.
- HeelFace Turn: She's so disgusted with Kugel's fleet that she ends up being the one to start the revolution. She later saves Pinon and is also seen on board the Gargantia in episode 13, flirting with Pinion. Meguru Kōro, Haruka confirms that she's now part of Gargantia.
- Psycho Lesbian: Played with. She's a ruthless pirate queen who keeps slaves chained to her throne, but we soon get indicators that this arrangement is more consensual and affectionate than one might expect. She also turns out to be Bi the Way.
- Rapunzel Hair: Indicates her vanity, her savagery, and the fact that she doesn't actually have to pay attention to mundane practicalities in order to kick your ass.
- Ship Tease: With Pinion
- Stripperiffic: Let's just say she does doesn't much.
- Younger Than They Look: She is 19 years old.
Storia and Ritona
Two people from Ridget's past. Storia is Ridget's childhood friend, while Ritona was an acquaintance of hers from another fleet.
- Childhood Friends: Storia is Ridget's childhood friend.
- Conveniently an Orphan: Storia, which makes it easier for her to leave Gargantia.
- The Engineer: Ritona is the head of a mechanical guild of his fleet. He also made a camera from scratch as a hobby.
- Florence Nightingale Effect: It's implied to have happened between the two.
- Hospital Hottie: Storia
- Love Triangle: Storia was in one with Ridget over Ritona. Storia ends up with Ritona, but they all part amicably.
A religious girl from a pirate fleet that is fighting a Succession Crisis against her half-sisters.
- Character Death: She dies from her illness after seeing Kugel's fleet.
- Chaste Teen: She remains a virgin to devote her life to Kugel.
- Cynicism Catalyst: To Kugel. Her death also convinces Striker that the humans of Earth have the same value system as the Alliance.
- Easy Evangelism: She views Kugel as an emissary for the "God of the Sky." Though to be fair, Kugel and Striker did save her bacon.
- Expy: She's virtually a carbon-copy of Amy, only with orange eyes. She even has a pet squirrel, for crying out loud!
- Family Theme Naming: She and her sisters have names that end with "-ria".
- Famous Last Words: "Beautiful..."
- Ill Girl: Poor Linaria has an illness that seems to feature symptoms of tuberculosis. She dies from this illness, kickstarting Kugel's Sanity Slippage.
- I Owe You My Life: She dedicates her life to Kugel after he saves her from Aleria's attack.
- Jack-of-All-Trades: She's a servant, top lieutenant, high priestess, and captain all at once. Did we mention that she's also Kugel's Love Interest as well?
- Love Interest: For Kugel.
- Rescue Romance: With Kugel after he defeats Aleria's pursuing pirates.
- Shadow Archetype: She's arguably what Amy would be under different circumstances. For example, Amy works to support her brother while Linaria is fighting against her sisters. Amy tries to help Ledo acclimate to Gargantia, while Linaria treats Kugel as a god and to some extent uses him to gain control of her fleet.
- Technicolor Eyes: Orange, to be specific.
- Too Good for This Sinful Earth: She may be one of the kindest souls on Earth, but she dies of her illness after befriending Kugel.
- The Unfavorite: Inverted; her father left the fleet to her... which leads her sisters Aleria, Onderia, and Kuraria to hunt her freighter down and kill all of her crew!
- Unwitting Instigator of Doom: In the long run, it was probably a bad thing to tell Kugel she wanted to die for the good of the fleet. Not to mention the fact that it's implied Kugel caught her disease.
Linaria's eldest half-sister. Along with her other half-sisters Onderia and Kuraria, she schemes to gain control of her father's fleet.
- Big Sister Bully: To Linaria, to the point of brutally murdering all of Linaria's crew when she tries to escape. Jeez!
- Boobs of Steel: She boasts the biggest rack of the pirate sisters and she also leads the pirate fleet in the second OVA.
- Bullying a Dragon: She attempts to purposely arouse the whale-squids by setting off depth charges in their territory. When they understandably attack the fleet, she begs Kugel to save them, thinking he would be easily slaughtered. She immediately regrets making this plan upon seeing him deliver a Curb-Stomp Battle to them and turn the ocean red from Hideauze blood.
- Burn the Witch!: She uses Linaria's conversion to worshiping the sky rather than the sea as an (rather flimsy) excuse to order Linaria killed.
- Character Death: She gets killed by Kugel after he sees through her lies.
- Death by Irony: Kugel decided to make Aleria's "promise" to sacrifice her life in order to be a priestess literal.
- Famous Last Words: "Thank you, Emissary."
- Impaled with Extreme Prejudice: Kugel saw right through her attempt to gain power by becoming the new priestess and gave the snake exactly what she deserved.
- Lack of Empathy:
- This bitch brutally butchered most of Linaria's crew and still continued to pound the latter's ship when Kugel arrives.
- She later gives a creepy Psychotic Smirk when she sees Kugel cradle Linaria's corpse in his arms. You sure show a lot of concern for your family, Aleria!
- Laser-Guided Karma: She attempts to suck up to Kugel and take Linaria's place as priestess immediately after the latter dies. Kugel sees right through it, kills Aleria, and uses then uses her image with Manipulative Editing to help institute the new "culling the weak" policy.
- Pirate Girl: She and her two younger sisters Onderia and Kuraria are the leaders of the pirate fleet.
- Smug Snake: Dear lord, is she ever.
- The Sociopath: A rare example in this series. She will do anything to gain control of the fleet, even if it includes offing her own sisters or betraying her own religion.
- Social Darwinist: Aleria hunts her sister Linaria down because she views the latter to be too weak to lead their father's fleet.
- The Starscream: After Kugel takes control. Both her attempts to take power fail.
- You Have Outlived Your Usefulness: Kugel kills her the instant he realizes she was trying to manipulate him, particularly as he was still grieving Linaria's death. He then uses her voice recording to start his culling the sick humans policy that is seen in the later episodes of the anime.
NOTE: The following section will have unmarked spoilers for the original anime
Introduced in Meguru Kōro, Haruka, Reema was originally a member of Kugel's fleet. After her fleet joined Gargantia's, Reema begins working as a messenger for Gargantia with the help of Amy.
At the end of part one, Reema talks to what appears to be a Machine Caliber, asking it to proceed to the next phase.
- The Mole: For a Land nation.
- Naïve Newcomer: Played with. While she's new to Gargantia she's shown to be a lot more perceptive (and talented) than she seems.
- Wrench Wench: At one point she asks about how a Yunboro part is made and gets pretty excited over it. It's implied that she has an interest in machinery, but she has become a messenger to learn more about Gargantia. She pilots a Yunboro herself to rescue Ledo in part one.
Ancient Machine Caliber/Muzzle
First seen at the end of first part of Meguru Kōro, Haruka and in the trailer of the second part. It is heavily implied that he is an ancient model, probably made by Continental Union because of his appearance. His body has a dark gray/black/cream color and he possesses a single cannon. He has an interface very similar to that of pre-ice age weapons, and his official artwork shows present-time symbols "A" and "3". He speaks with an unknown language.
- Lost Technology: Heavily implied to be one in the second part of OVA because of his appearance and interface being far more advanced than Yunboros, but inferior to Chamber. And, just like most of the antedeluvian tech, he is still functional after hundreds of years.
