The main protagonist, he finds himself thrust into the conflict with the Secrets after a run in with Gazelle leads him to the Nirvash. From there he begins piloting it to save his island home. Pilots RA272 Nirvash, called the Nirvash Mark I in series.
Generation Xerox: Just like his father, Ao begins the series living alone with his grandfather. His mother vanished when he was young, just like Renton's older sister Diane* In fact, the scene where Eureka leaves is practically a Call Back to Diane leaving., and they're both outsiders in their respective hometowns.
Half-Human Hybrid: Half-human, half-Coralian. The latter seems to be the dominant side as far as physical characteristics are concerned.
Instant Expert: Ao learned to pilot an FP at an improbably young age (Gazelle even comments on it), and picks up IFO piloting on the fly (literally). Having inherited his mother's ability to see trapar, he can ride the wind with far more skill than any human could ever manage.
Subverted later on; though Ao is a decent pilot, that represents the whole of his experience in the matter. The more technical aspects of the Nirvash elude him. It takes him a while to figure out how to deploy the weapons (other than the head-mounted machine guns), and Fleur has to teach him how to use the radio. Fleur won't let him live this down. When she gets stuck at his house during a lockdown, she claims he wouldn't have been able to answer the phone without her.
In the Blood: Piloting seems to be a skill he inherited from his parents. His ability to "see the wind" is inherited from his mother.
I Thought Everyone Could Do That: His ability to "see the wind", which is actually the ability to see trapar. He's surprised to learn other people can't see it, and it becomes a problem when he's in space (where there is close to no trapar).
Parental Abandonment: Renton couldn't follow, for whatever reason, and Eureka disappeared when he was two. Ao at least acknowledges his father's absence, and plans to "give him a good beating" when he meets him. The events of episode 13 suggest Eureka never told him about Renton, given he doesn't even know his father's name until that point.
Prior to the start of the series, Ao had assumed that his father abandoned him and his mother.
She Is Not My Girlfriend: To Naru. It even comes up when he's not around. When Elena calls her such in episode 22, Fleur pops up on the video link just to say that Naru's not his girlfriend.
Strong Family Resemblance: He looks a lot like his mother (if you made her male), with a bit of Renton thrown in (which is more apparent when he had brown hair). This is particularly noticeable in the OVA, where Elena and Fleur force him to dress like his mother (specifically the outfit she wore in the previous series) for over half the episode.
Ao's childhood friend, a daughter of one of the island's prominent families. She was one of the survivors of the first Scub Burst that happened soon after Eureka appeared on the island, and which killed her mother and left her an Ill Girl. All this has earned Eureka and Ao the hatred of her father. As of episode 14 she pilots Eureka's Nirvash typeZERO spec2.
Bare Your Midriff: Her top is rather short. She gets a gown to replace it in episode 14.
Big Damn Heroes: She uses the Scub to protect Ao from Truth, teleporting him to Okinawa.
Decoy Protagonist: The opening makes her look like a main character. She gets downgraded considerably by episode 5, when the island ceases to be the primary setting. Even when she regains some importance later, her appearances are erratic at best.
Evil Is Not a Toy: She tries to merge Truth with the Scub to use his power to further her agenda. It doesn't seem to occur to her that he's a goddamn psychopath who's been actively trying to destroy it for pretty much the entire series. This goes about as well as you'd expect.
Hair Decorations: Episode 14 onward, though it isn't until episode 22 that they're actually confirmed as such (Ao thought they part of her).
Green Thumb: After being absorbed into the Scub in episode 12 and seeing the origin of the Scub, she gains the ability to control both Scub and regular coral, with which the Scub merged to survived.
Portal Network: She can teleport herself and other objects from one Scub to another.
Ill Girl: The Scub Burst left her in need of periodic oxygen therapy, and she always carries a portable inhalator with her. Later it turns out that trapar rich air is much more effective.
Instant Expert: She is suddenly able to fly an IFO in episode 14. There's no evidence to suggest she's ever driven anything in her life, given how Ao's ability to fly a FP is explicitly treated as abnormal. This may be explained by her Scub Coral infection and the Nirvash being alive, which together might let her fly it without the needed skill.
I Owe You My Life: She goes with Truth is because she believes he was the giant that rescued her from the Scub Burst. Her personal flashbacks seem to be a slight example of Self-Serving Memory (or Truth's manipulation), since a non-POV flashback of the event is much more vague.
Magic Skirt: Her gown after episode 14. Given how wide it is at the base, so much as a gust should send it flying up, but it stays down. Good thing, too, since one of her appearances in Ao's dreams suggests she isn't wearing anything beneath it.
Master of the Mixed Message: She gets mad at Ao for thinking she's in love with Truth. Because it's not like she spent more than half the series following him around or anything. Then, in episode 23, after last episode set up what looked like a Heel-Face Turn, she does a complete 180, attacks all of Team Pied Piper because she doesn't think they can win, then runs off with Truth again.
Missing Mom: Died in the Scub Burst which left Naru ill.
Moral Myopia: In episode 12, she thanks Truth for his kindness, and shortly after the camera cuts to the rubble of the trapar mine he destroyed and the dead bodies of the workers.
Well-Intentioned Extremist: Naru is actually trying to improve humanity by ensuring they have symbiosis with the Scub Coral. She simply isn't bothering to ask if that's what people want, much like the Scub did when they arrived in the proper timeline, and they at least had the excuse of being entirely ignorant of humanity's resistance.
What Could Have Been: Supposedly Naru was going to be a member of Generation Bleu, but the story was changed.
Generation Bleu is a multinational organization funded by the UN to deal with Scub Bursts and the Secrets which appear with them. Though UN subordinates on paper, they operate as mercenaries in practice, offering their services for a price.
Team Pied Piper
One of the Generation Bleu rapid response teams. They operate from the Triton.
Voiced by: Tetsuo Goto (Japanese), John Swasey (English)
Triton's owner-captain and the team leader. A very tall and powerful man in his forties, he's an arguably both a Reasonable Authority Figureand a Bunny-Ears Lawyer, being a skilled leader and sly negotiator, but also highly eccentric, like, actually, most of his team.
The Atoner: The reason he joined Generation Bleu was to repent for his sins when he was a soldier.
Badass: He's a former soldier, and fired on a Secret with a rocket launcher.
Big Good: He has this role after episode 20, since just about everyone else higher up than him is dead, turned traitor, or abandoned ship.
The Big Guy: Generally two heads taller than most of the Iwato Jima's grown men.
Blond Guys Are Evil: Destroyed from his very first moments. There really isn't anyone more considerate and devoted to the Right Thing in the whole series.
Bunny-Ears Lawyer: He's a very competent leader, but he's also highly unconventional and unpredictable, and periodically has a really weird moments. Like when he refused to pick up a phone, justifying it by the fact that his coffee mug is too full.
Dark and Troubled Past: He was a soldier during a Balkan war that resulted in the death of his family and the dissolution of his own country. Previous to that, his soldiering is how he knows Eureka; he was part of an apparently multinational team of soldiers to help Eureka stop a Secret.
Papa Wolf: In his own words, "I won't let children die." Letting them pilot IFOs is a necessary evil, since adults can't, but if push comes to shove he's willing to give his own life to protect them.
Refusal of the Call: He was offered a position in Generation Bleu right after the disappearance of Eureka, but turned it down since he had troubles in his own country to deal with. Thanks to the events noted above, he eventually comes to accept the offer.
Dark and Troubled Past: She was a member of an American PR company that is the mother company of Generation Bleu. During a civil war in the Balkan Peninsula she and the company faked claims of genocide so that other countries wouldn't intervene in the conflict - though Rebecka says there was no good or evil in that conflict. The result led to the dissolution of Ivica's home country.
Drill Sergeant Nasty: She's a bit of a martinet, and prefers simpler and harsher decisions in difficult situations.
Screw the Rules, I'm Doing What's Right: Often has to bend the rules in the face of bureaucrats trying to manipulate life-or-death situations for their own benefits. This culminates in her cutting ties with Big Blue World in episode 20 to help Team Pied Piper.
One of the team's IFO pilots, an eccentric Otaku girl who is a practically One of Us. However, there are hints that she is more than she seems. Pilots the RA304 Kyrie, and later takes the RA302 Credo. In episode 21, it's revealed that her real name is Ellen Brooks, and she's actually from 1981, having been brought forward by Eureka to save her life.
Ambiguously Brown: It's eventually explained that she was brought to the future from a Scub Burst in the Caribbean Sea.
She starts freaking out when Eureka's around, to the point where she charges after Eureka when she tries to return home. This is because Eureka took her from her own timeline to save her. In doing so, Elena saw images of Eureka's world and wanted to go there.
She also freaks out in episode 18 when Ao leaves. This is because she believes Ao can get her back home.
Dead Person Impersonation: There is an Elena Peoples, but she's a little girl who died during a Scub Burst. This Elena is just using the name. Then there's her impersonation of Miller Joe, whom she killed.
By impersonating Miller Joe she has been feeding data to the Americans. The problem is that she's feeding correct data, and seems to be doing it on her own initiative rather than Generation Bleu's. She gave it up not long after it was revealed, but it was going on for several months at least.
Heel-Face Revolving Door: Due to thinking she's an outsider in this world she doesn't feel any strong attachment to any side and thus switches sides easily, like in episode 20, when she offers to defect to the Americans. Ao manages to calm her down and get her back on his side.
Idol Singer: Good enough to take over for an actual one with no one noticing for months.
I Just Want to Be Special: Suggested in episode 21. She's not actually from the original timeline, and it's hinted that she knows this, but having seen a world where a couple carved their names on the moon, she desperately wanted to be a part of it.
Master of Disguise: Has been impersonating Miller Joe, who was a spy for the Americans before Elena killed her. The disguise isn't perfect, though; upon realizing that something seems amiss, they quickly identify a slight vocal difference, and her facial structure isn't close enough to fool recognition software.
Ms. Fanservice: In episode 17, she and Fleur have to wear revealing outfits for a photo shoot. Fleur is embarrassed, but Elena just goes with it. And that's not even getting into the numerous times she's been seen in the shower.
Mysterious Past: Episode 11 raises a ton of questions about her origins, which even she is apparently unclear about. She reveals in episode 19 that she is from the original timeline, and that Eureka brought her to this one for some reason. Eureka reveals the truth in episode 21; while she saw images of the original timeline, she is not from it. Eureka picked her up in a Scub Burst and dropped her back off forty years later to save her.
Red Herring: There were a lot of hints that she was from the original series timeline. There was even a potential explanation with the reveal that Ao may have a sister somewhere. She's not related to Ao, nor is she from the original series timeline; she just caught a glimpse of it while time traveling.
Shipper on Deck: In episode 8, she ships Ao and Fleur to an exaggerated extent. When Ao takes off in anger and Fleur chases after him, she assumes they're eloping.
Missing Mom: She died in a car accident. Specifically, both she and Fleur were in that accident, and the doctors could only save one by taking organs from the other. Fleur was the recipient, apparently on her father's suggestion.
The Rival: Sees herself as such to Ao. That said, she is pretty friendly to him, especially when they start to bond over their mutual dislike of their fathers.
Scars Are Forever: Still has her scar from the operation that saved her life and killed her mom.
Survivor Guilt: She hates the fact that her mother's organs were used to save her life. She took her piloting job precisely because it's something of a slap in the face to that (she believes her father made the choice, hence she's getting back at him for it).
Another Generation Bleu rapid response team. They operate from the Medon, a ship identical to the Triton in all but color. The team (though not its members) ceases to exist in episode 16, after AO wipes out the Secret army with his new Wave Motion Gun and as a consequence prevents the Norwegian Scub Coral from ever appearing. This in turn causes the McCaffrey family to never move to the Coral Plant established there, so they continue to live as ordinary bakers. Bruno's fate is not elaborated upon, while Maggie instead became an IFO pilot for the Americans.
Voiced by: Yu Shimaka (Japanese), David Wald (English)
Team leader and captain of the Medon.
The Big Guy: He's chubby in comparison to Ivica, but still quite big.
Heroic Sacrifice: Flies the Medon into the Secret to stop it temporarily, allowing Team Pied Piper to rescue his pilots.
Sacrificial Lion: The Medon is destroyed, and him with it, in the episode following his first appearance.
Team Dad: He tries to encourage Ao not to join Pied Piper, reasoning that those he cares for would be saddened by it. When Ao stops by his apartment later, he's shown to be very dedicated to his work, almost obsessively so.
What the Hell, Hero?: A non-verbal one. When Ao is looking around Bruno's apartment as it's being cleaned out, he finds a map with reports of various Scub incidents pinned to it. The report pertaining to Iwato Jima, and thus him, is quite vocal about why it was a terrible mistake to ever let him fight in the first place, with "Never let children die!!" written on it by hand. Bruno didn't actually write the report, but the handwritten note is his.
Voiced by:Nao Touyama (Japanese), Kristi Kang (English)
The team on Orbital Fortress Poseidon, Generation Bleu's Space Station. They guard the quartz collected by Generation Bleu's pilots. The Poseidon is destroyed by Truth, but they manage to escape its destruction in their ship "Great Proteus".
Batman Gambit: It's implied she requested Pied Piper's help specifically so she could get Ao as part of her team (out of scientific curiosity). Though she denies it, it's clear she knew coming in pretty much exactly how Ao would react to being in space.
Fake Defector: Her team the Allied Forces against Pied Piper. She later explains that she did it to buy time for them.
Voiced by:Akio Nojima (Japanese), Charlie Campbell (English)
The lead mechanic for Generation Bleu. He and his team maintain the IFOs.
Badass Grandpa: The man is not young by any measure, but he still dove onto the Nirvash while it was in motion (though admittedly, it wasn't moving all that fast) in order to manually shut it down before Ao could leave without authorization.
Badass: He managed to stop the Scub Bursts by negotiating with the Secrets, forcing them to stop attacking lest he have Ao use the Quartz Gun to keep destroying them.
Benevolent Boss: Ostensibly. He gave Gazelle and his friends a job on the grounds that they deserved a chance. The fact that they had discovered classified information about the Scub Coral at best seemed to amuse him slightly, while Rebecka treated it as a severe-enough breach to potentially silence them for. He has also shown a consistent desire to keep his pilots happy, such as sending Chloe a box of doughnuts while she was recovering. However, this seems to be something of a front for more manipulative behavior. He let Ao off the hook for a major breach in protocol, only to have him tailed by Gazelle and his friends in such a way that he'd know he was being watched. Both Fleur and Elena recognize that his kindly demeanor isn't exactly on the level.
In the end though, he was still this trope, ensuring that the remaining members were taken care of when things went pear-shaped.
Heroic Sacrifice: He locks himself with Truth in Generation Bleu's Quartz silo, then releases the Quartz which he booby-traped to crush Truth, having deduced that Truth is a Secret and that the resulting reaction, at the very least, would cause him some harm.
Senseless Sacrifice: Unfortunately, it doesn't work. It just forced Truth to possess an LFO instead.
Guile Hero: As one example, in episode 8 he manipulates the world and pressures America into allowing a mission in Faisal Arabia.
Papa Wolf: Do you doubt he's one? Ask Truth. Once he digs his way out of the giant mass of Quartz Christophe crushed him with.
Berserk Button: Getting interrupted is one thing. He puts up with that. Talking over him is another. This is signified by his circle eye changing into a triangle as a crude angry face.
Demonic Possession: Of sorts. Han links a Secret to Georg in an effort to communicate, which due to synchronization between all the Generation Blue Georgs leads to it being able to communicate through all of them when it wishes.
Have You Tried Rebooting?: Ultimately, they deal with this by rolling back Georg to an earlier version, since they'd look even worse if it were discovered they were on speaking terms with the Secrets. Secret!Georg still exists as an independent program. Subverted, though. Since Georg was uninstalled but never reinstalled, while Secret!Georg survived in certain protected systems, the latter has effectively taken complete control.
The liaison between Generation Bleu and its parent company, Big Blue World. It's his job to keep Christophe in line with the company's goals, though his success in this matter tends to vary. He also keeps an eye on some of its more valuable assets. He temporarily takes over leadership of Team Goldilocks after Bruno's demise, until the team is erased from history and that never happened.
Commander Contrarian: Marginally. He's shown at multiple points not to approve of Christophe's methods, mainly because he usually doesn't act in the company's best interests.
The people of the Iwato Jima, the Okinawan island where Eureka landed and given birth to Ao. Because the Scub Bursts started to happen soon after, the island's inhabitants, with a few notable exceptions, blamed it all on her and Ao. In addition, they also vented their frustration at Okinawa's half-assed independence on them.
Voiced by: Masafumi Kimura (Japanese), Phil Parsons (English)
Naru's father and one of the community leaders. His wife died in the first Scub Burst that also injured Naru, and he has since hated Ao and Eureka with a passion. There's hints that he was the one who betrayed Eureka to the Americans.
Jerkass: There's a very slight hint of him having a heart of gold somewhere, though. Despite his clear disapproval of their friendship, he let Naru go see Ao in episode 4 with no apparent protest. The fact that Ao has saved the island twice by this point might have motivated that change in attitude.
Living with the Villain: Naru comes back to live with her family in episode 21, leading to very uncomfortable silences all-around.
Think of the Children!: This is how his hatred of Ao and Eureka manifests. Since the Scub Burst killed his wife and left his daughter quite ill, he believes Ao will draw the island's children into the same type of conflict that the adults had to deal with ten years ago. He even tries to use this excuse with Fukai (Fukai rightfully counters that Ao is as much a child of the island as the rest are).
Voiced by: Naomi Kasumi (Japanese), Mark Stoddard (English)
Gazelle's father, a famous folk singer and sanshin player, also one of the island's leaders. A very traditional man, he seems to be against Ao in no small part due to racism.
Hero with Bad Publicity: How he thinks of himself after the Scub Burst is handled. With the Allied Forces capitalizing on it as a new trapar mine and bringing prosperity to the island, he's the only one still dedicated to the cause of independence. Any attempt to act on it would be treated negatively.
Pick on Someone Your Own Size: Since we don't know how he treated Eureka on the past, we instead get his present-self who targets children to get independence instead of actually doing something about it. He's called on it more than once.
Politically Incorrect Villain: As if his attitude toward Ao weren't bad enough, he also gets on Naru's case after the coral infections begin spreading. Understandably, though, he's less willing to mess with the girl who has what amounts to an army and magic powers.
Spell My Name with an S: His surname, 金城, can be read both as Kinjou (as on the official site) and as Kaneshiro (like on posters).
Taking Up The Mantle: Wants Gazelle to do this. Gazelle dismisses it; his father never felt him capable of it before, only to suddenly ask now.
Voiced by: Tetsuo Komura (Japanese), Brian Mathis (English)
Pippo's father and an officer in the Okinawan Self-Defense Forces. He's Iwato Jima's militia commander and seems to be somewhat less of a jerk and more politically motivated, as he wants to trade Ao for full Okinawan independence.
My Country, Right or Wrong: He doesn't hold any ill will toward Ao, and authorizes his return to the island later on. In that same episode, though, he immediately goes back on that deal when the Japanese pressure Okinawa into turning Ao over as a murder suspect.
Voiced by: Takuya Kirimoto (Japanese), Brandon Potter (English)
Kazuyuki's son and the head of a small courier company (no questions asked) that he runs on Iwato Jima. He's estranged from his father and actually regrets bullying Ao earlier on his instigation. A shrewd and cunning smuggler, it's during a job for the JAF that he ends up with the key to the Nirvash, and from there brings Ao into the conflict. He and his crew stow away and follow Ao to Switzerland, where he forces the president of Generation Blue to hire them as investigators, and uses that position to try to figure what's going on with the world.
Batman Gambit: Does this to Fleur in Episode 18 so she would go rescue Ao.
Heel-Face Turn: Regrets bullying Ao in the past and basically becomes his ally after Ao pilots the Nirvash.
Hidden Depths: He acts apathetic and sloppy, but he's got a sharp mind and has more figured out about what's really going on than most of the rest of the cast at any given point (though due to a general lack of information and/or clarity, still gets surprised often).
Jerk with a Heart of Gold: His first on-screen meeting with Ao has the two fighting over his recent accident, Gazelle having swerved to avoid Ao on the beach during an emergency landing. Later on, he's nothing but even-handed with Ao.
Voiced by: Yoshinori Fujita (Japanese), Anthony Bowling (English)
The third in Gazelle's company, he's a skilled hacker and information gatherer. His father runs a prominent trapar mining company (which one is not specified), and his name is well-known enough that Nakamura knew of him by reputation alone. Being a multinational and multiracial, he has no stake in the political struggle around Okinawa and thus sometimes comes off as cold and indifferent.
Iwato Jima's physician, he was the only one of the island's elders who was against the common "let's blame everything on the blue-haired people" attitude prevalent there. He took in Eureka and hid her until she disappeared, and then adopted Ao as his grandson.
Naru's pet sloth. When Ao leaves to join Generation Bleu she gives Noah to him.
Amplified Animal Aptitude: At times he seems far more competent than he should be. In episode 3, he tries to untie Ao while the adults aren't paying attention. He even appears to be reading in two different episodes.
A JSDF Military Intelligence officer hell-bent on obtaining the trapar technology for Japan. Japan, being isolated from the world community due to the whole Okinawa debacle, and lacking a Scub Coral that could be used for trapar production, lags behind the rest of the world significantly, so he is set on correcting this. Still, his junior status and over the top ways mean that he's mostly ignored even by his own side. By the end of episode 9 he begins working with Truth.
Only One Name: Nakamura is presumably his last name, but it's never made clear and no one has ever referred to him by any other name. Even the official website only lists the one name.
The last episode finally reveals his name is Yasumochi Nakamura.
Patriotic Fervor: The Secret unfavorably compared him to Hitler, Napoleon, and Alexander in this regard. He ends up resigning from the military in episode 21, since they allied with Pied Piper and derailed his plans.
Sideways Smile: In later episodes, as a consequence of working for Truth. It really isn't good for one's peace of mind.
Teeth-Clenched Teamwork: He and Truth get along about as well as can be expected for two villains with barely any goals in common. Nakamura has even pulled a gun on him (which Truth casually bent into uselessness).
Tempting Fate: Their soldiers will be fine! Secrets only target Scub Coral.
Would Hurt a Child: He tries to shoot Ao to keep him from getting to the Nirvash in episode 14. Fortunately, everyone else is appalled by his behavior and restrains him before he can get a shot off.
Major Niki Tanaka
Voiced by: Tomeyushi Hyuga (Japanese), Andrew Chandler (English)
USAF officer apparently responsible for Scub phenomena observation. So far he has proved largely a neutral force, concentrating on information gathering and observations, rather than on a direct actions.
Overt Operative: He doesn't even try to hide — because he doesn't need to. His official cover is "American agent".
Reasonable Authority Figure: When he shows up to take Ao into protective custody in episode 17, he doesn't try to threaten Ao into cooperating (he did have an IFO squadron with him, but that was likely meant to keep the Chinese at bay). Instead, he gives a simple reason why Ao is better off coming with him, which is enough to get Ao to come quietly.
Strange Bedfellows: He helped Han and Pippo to link the Secret's head with Georg. Later on, he offers to put Ao in protective custody, citing Generation Bleu's suffering reputation in the wake of the latest Secret attack.
Wouldn't Hurt a Child: He pulls a gun on Ao to stop him from leaving in episode 18, but lets Ao go when Ao refuses to back down.
A scientist who published a book explaining how the current world is wrong due to interference in history by the Scub Coral and Secrets. He is variously regarded as a quack or a prophet. With Nakamura trying to spin the Secrets as the protectors of mankind, his book is becoming much more popular.
The Cuckoolander Was Right: Most of the world regards him as a quack. He also happens to be completely right. Truth told him everything about the other world.
A mysterious character who doesn't even know who he is. He goes around causing conflict in an effort to discover that fact. He's actually a Secret in human form, the same Secret which fought Eureka before she vanished ten years ago. Johansen found him in the aftermath of the Okinawan Scub Burst. In episode 20, he merges with the Kanon, an LFO archetype kept in the basement of Generation Bleu, after Christophe Blanc tries to kill him with a Quartz explosion.
Came Back Strong: To the point that it's stated only another archetype can beat him now.
The Cracker: He's a member of the "Fire Crackers", a hacking group. In fact, he's actually the entire group. He's able to hack into a missile defense satellite in episode 12. Episode 19 reveals that he's actually a technopath, hence why he's so freakishly good at it.
Cryptic Conversation: More like Cryptic Soliloquies, since he often speaks aloud when no-one is there to listen.
Desperately Looking for a Purpose in Life: And violently so, at that. Seeing the Nirvash evidently provides him with inspiration in that regard. After choosing his name, he claims to be seeking the "truth" of the world. Episode 19 reveals this is in fact the very reason behind his creation. When Eureka took the Quartz at Okinawa without killing the Secret trying to destroy it, the Secret could only reconcile its lack of purpose by merging with the Scub and taking on human form.
For the Evulz: He admits to Naru he was trying to use the Secrets and the Scub Coral to cause chaos.
Gender Bender: One of the forms he takes is a woman. One notable aspect of this form is that it retains the exotic eyes of his default form. Gets doubly disturbing in episode 13, where he takes two female forms and shapeshifts only his head back to normal while talking. Worse still, one of these was Eureka. You can scream in agony now.
Hand Blast: He can fire bolts of energy strong enough to blow up an armored FP or a small building. He does this with a Finger Gun at one point.
Invincible Villain: Going hand in hand with being an Outside-Context Villain, the guy is basically indestructible. He's shown to be bulletproof even when caught off-guard, can fly at speeds matching or exceeding most IFOs, can shield himself from attacks that would shred armored vehicles, and can fire energy blasts that can destroy small buildings. Even a Quartz explosion, which is supposed to kill Secrets, fails to bring him down.
Irony: His goal in life is to discover the truth. When he finally learns it, he outright refuses to accept it.
Nietzsche Wannabe: Believes the world is wrong and nothing can fix it. He passed these ideas on to his adopted father, Johansen.
No One Could Survive That: In episode 19, Christophe crushes him with a bunch of Quartz storage tanks. Since Truth is a Secret, the two react and cause a massive explosion. He comes back in the next episode merged with an LFO archetype called Kanon.
Oh Crap: Surprisingly, he's still capable of this even with all his power.
One-Winged Angel: His monstrous shadow-like form. His Secret form would technically count, if he ever used it in whole. In episode 20, his transformation into a Secret/LFO hybrid could also be seen as this.
Out-Gambitted: He learns in episode 19 that, for all his attempts at manipulation, Naru has been playing him. Probably not the whole time, but presumably after episode 14.
Outside-Context Villain: He appears with no prior build-up in episode 6, sees the Nirvash in action, announces that he was waiting for something like it, and then goes to attack Generation Bleu. He is not aligned with any of the factions, nor does he seem to have an allegiance to the Secrets. Finally, he possess superpowers in a Humongous Mecha series.
Pet the Dog: As Naru points out, he could have killed Ao by now, were he so inclined. Truth believes that Ao has the potential to see the truth of the world, which is probably why he hasn't bothered.
Power Glows: The jewel on his belt glows. His eyes also glow occasionally.
Psychic Powers: He's a powerful telekinetic, able to lift cars, levitate, and moves an entire store from Phoenix to the Grand Canyon (which may have involved teleportation given how cleanly he did it). He may also be a telepath, given his ability to infiltrate almost any organization he wants. He may have put Ao through a Dream Sequence, during which he took off with Naru, which left Ao unconscious for three days. Naru later explains that Ao's consciousness was there, which implies Truth was responsible.
Ramming Always Works: Half of his combat strategy when merged with the Kanon is to just run into everything, since his mech is indestructible.
Shapeshifter Default Form: Type B. His white-haired form seen in the opening is the one he switches to when not bothering to hide his identity. Naru's vision shows that this is his true human form, having manifested as a human child when Johansen found him. His actual form is that of the humanoid Secrets.
Shapeshifter Weapon: He can transform his hands into giant Secret hands, strong enough to wrestle an IFO.
Technopath: Revealed to be the source of his hacking abilities in episode 19.
He really cannot stand getting beaten because he's damned near indestructible. Episodes 13 and 14 are great examples of this, showing his face devolve into almost-deformed expressions of anger reminiscent of Haruhara Haruko'sangry◊ face,◊ where she loses her composure so much that she seems to lose control of her body.
He truly loses it in episode 19, when he learns he's a Secret in human form. Remember what we said about Haruko's angry face? He looks like that pretty much constantly. Which is rather satisfying in a weird way.
Villainous BSOD: Pretty much all of the episode 19, after both Naru and the Secret head told him that he's a Secret — which he obviously is unable to remember (and accept) at all.
Ao's Missing Mom. 13 years before the series begins, she fell from the sky into the ocean. She was rescued by Mitsuo Arata and gave birth to Ao on Okinawa. She disappeared under mysterious circumstances in the Okinawan Scub Burst ten years ago. In the present, she appears in episode 12, except from her perspective that hasn't happened yet. She is the original pilot of the Nirvash Mark I, while her past self piloted the Nirvash typeZERO spec2.Unless specifically noted below, most of the personality tropes she had in the first series still apply.
Adorkable: When she's not being serious, she tends to come off as this. Of particular note are her reactions to someone mentioning the Deface of the Moon in her time or Renton.
The Ageless: Coralians never age, so Eureka is effectively a permanent teenager regardless of her real age. She still looks the same as she did in the original series, presumably several years ago to her. Still, she manages to give an impression of the older age through the longer hair and more conservative outfit.
Pregnant Badass: If push comes to shove, being six months pregnant won't stop her from doling out a much-needed beatdown.
Spirit Advisor: She can occasionally intersect with Ao's timeline to give advice. She appears before Ao a couple times, and tries to reason with Naru in episode 14 (though Naru ignores her). Elena gets a chance to talk to her in episode 21, which was quite a surprise to Eureka herself (she expected to find Ao).
Time Travel: The Eureka that appears in episode 12 is from before she gave birth to Ao, far enough that she's currently pregnant with Ao's older sister. She also pulled Elena from her own time period to 40 years into the future to save her.
Ao's Disappeared Dad and husband of Eureka. When he and Eureka were doing experiments on the disappearance of Scub Coral in their world, she and the Nirvash spec2 were taken by the Scub, leaving him behind. She came back at some point, only to leave again with the Mark 1 Nirvash sometime later. He finally shows up in episode 22, a resident of the Bad Future. Seeing the telltale pillar of lights that are associated with Time Travel, he takes his Nirvash, modeled after the Nirvash specV from the movie, and heads for the past.
