A child prodigy and Whispered like his younger sister, he is known as "Mr. Silver" in the executive circle of the Amalgam organization. Is extremely infatuated with Kaname.
- Abusive Parent: His mom sold him out by handing him over to armed men since hes the only one who knows of her affair with another Navy officer.
- Alas, Poor Villain:After he's killed, Sousuke clearly isn't happy about his passing and laments not getting to talk with him more. Teletha is also seen putting flowers by his grave later.
- The Archer: During the final battle at Merida Island, the Belial is equipped with a large bowgun that can apparently penetrate Lambda Driver forcefields (or else fires so quickly that it can hit before the forcefield fully manifests).
- Badass Bookworm: He's regarded as the most intelligent of the Whispered and also a capable AS pilot, who can take down Sousuke's Lambda Driver and has the skills to give him a run for his money as a shooter.
- Badass Longcoat: So badass, it even blocks throwing knives (and bullets) aimed to the head.
- Big Bad: As soon as Leonard appears he begins manipulating Amalgam and antagonizing the heroes in the name of ushering in his idea of world peace.
- Berserk Button: His mother's affair. During the final battle, Sousuke says "Tessa wanted me to remind you of 'what she did'"; just those words are enough to enrage Leonard, which makes him lose focus and leaves him open to Sousuke's attacks.
- Bishōnen: To the point of being Dude Looks Like a Lady.
- The Casanova: The novels state that he has had many sexual partners and is even heard having sex with a woman over the phone.
- Child Prodigy: Grew up one, having solved one of Einstein's equations by the age of four.
- Crazy Jealous Guy: He hates how Sousuke keeps getting in his way of not only his goal, but winning over Kaname. He can never seem to understand why anyone would ever accept Sousuke at all. Especially as a romantic interest no less.
- Curtains Match the Window: Same as his sister, with gray eyes with silver hair.
- Domestic Abuse: Poor Kaname. He not only slaps her hard enough to hit the ground but to draw blood and even Mind Rape her too.
- Dropped a Bridge on Him: After being defeated by Sousuke the two begin to talk to one-another, with Sousuke hoping he can break through to Leonard and Leonard buying time to activate the island's self destruct button on his remote. Neither are successful, as Leonard is shot dead by Kalinin, mid-sentence. Even Sousuke states he wishes they had more time to talk.
- Energy Bow: The Belial's is equipped with some sort of bow that fire lambda-laced projectiles that can punch through anything.
- Even Bad Men Love Their Mamas: Subverted, Leonard has nothing but hate towards his mother, she hid Tessa and then used him as a shield because he found out she was cheating on his dad.
- Face of an Angel, Mind of a Demon: A raging pretty boy, but also the most flat out dangerous leader of Amalgam.
- Faux Affably Evil: At first he insisted he loved Kaname and wanted to win her affection honestly until she accidentally shoots him, he drops the "gentlemanly act" and the very first thing he does when they meet again is to belt her across the face and tell her to shut up.
- Forceful Kiss: Did this to Kaname twice! Almost three, but she was Brainwashed and Crazy.
- Green-Eyed Monster: He not only hates Sousuke, but is very jealous of him. A LOT. It not only involves Kaname, but in general too. He hates how people are easily attracted by Sousuke, who can be aloof, stoic, and awkward, yet his loved ones are much more forgiving towards him. Even though he's killed over hundreds of people. What pisses him off more than anything, is that he believes that he and Sousuke are Not So Different and so questions Kaname's repeatedly; why she would show such strong care and emotion for someone like him.
- The Gunslinger: Surprised? So was Sousuke and he's good enough to give him a run for his own money.
- Icy Gray Eyes: His gray eyes are the cold and superior type, as he is an aloof young man, who thinks he and he alone will be the one to set humanity on the right path.
- If I Can't Have You...: He won't kill Kaname, but he's not above slapping her, yelling at her, threatening Sousuke, letting her get Brainwashed and Crazy, and resetting the world in where Sousuke won't remember her. So yeah, he gives off this vibe quite a bit.
- I Have You Now, My Pretty: His two Forceful Kisses and his Crazy Jealous Guy/Yandere tendencies really get to Kaname.
- Just Giving Orders: He honestly believes that he's got a clean conscience because he has never killed anyone directly, just given orders that resulted in people getting killed.
- Lack of Empathy: Is worst than Sousuke, but not on the same level as Gates or Gauron.
- Love Makes You Evil: He begins to lose it when Kaname unintentionally shoots him in the head and overhears Kaname and Sousuke proclaiming their love to each other. He starts to get darker and more possessive towards Kaname.
- Moral Dissonance: He considers himself to be morally superior to Sousuke, because Sousuke has killed and he has not. This completely ignores the fact that while he has never killed anyone with his own hands, the number of people who have died or been put in mortal peril due to his actions far exceeds the number of people Sousuke has killed. How is ordering the death or deliberate endangerment of thousands better than killing hundreds in person?
- Murder Is the Best Solution: It doesn't matter to him how many lives he must sacrifice, because once he reaches his goal, it will be corrected and it will be as if it never happened. Just as long as no one gets in his way.
- Murder the Hypotenuse: Sousuke gets a double whammy. He's in Leonard's way of both his plans and winning Kaname over completely. So of course, Sousuke is at the top of Leonard's hit list for two very good reasons.
- Names to Run Away from Really Fast: Leonard's personal AS is named the Belial, a name associated with The Devil.
- Narcissist: Unlike Garon and Gates he is capable of caring about people, at least, in his own creepy way but he really, really likes himself and believes he's a brilliant revolutionary who can save the world.
- Not Good with Rejection:
- He doesn't react well to Tessa siding with Sousuke and even though she's well aware of what their mother did to him, she still chooses to oppose him.
- At first he was somewhat laidback about Kaname dismissing his advances. Didn't care that she slapped him or insulted him to his face. Later on, however, he becomes so enraged with Kaname not giving in to him, and sort of "betraying" him by finally declaring to Sousuke that she loves him, that he slaps her hard enough to make her fall to the ground, speaks to her very rudely, and generally tortures her (more mentally than physically) in order to weaken her mind so that she won't be able to resist his plans of world-domination.
- Really Gets Around: Upon being first mentioned in the novels, he's referred to as a loose playboy who frequently sleeps around.
- Set Right What Once Went Wrong: He's aware that the Yamsk 11 incident changed the course of human history, and is convinced that the timeline in which FMP occurs is fundamentally wrong; thus his ultimate goal is to change history, which he believes will result in a more peaceful world.
- Smug Snake: A very high functioning and intelligent one. Nevertheless, Leonard firmly believes himself to be an absolutely brilliant young man and is prone to freak outs when he doesn't get his way. In one brutal moment he hits Kaname for wanting to be with Sosuke instead of him.
- Stalker with a Crush: On Kaname, who he introduces himself to by forcing a kiss on. Later he kidnaps her and despite promising to make her fall for her in a fair, romantic fashion, devolves to screaming at her (even hitting her on one occasion and even going so far as to use mind control so that she will love him back.
- Teen Genius: Even more so than Tessa, being the most referred to as the most intelligent of the Whispered. In particular, he excels in the creation of Arm Slaves.
- Unskilled, but Strong: Leonard Testarossa isn't a very good pilot, but his Belial is equipped with the Lambda Driver, a device driven by the user's willpower that lets them perform feats that defy the laws of physics; since Leonard has tons of willpower, the Belial is practically invincible.
- Well-Intentioned Extremist: Despite causing massive death and destruction, he honestly believes that his plan will make the world a better place.
- Wicked Cultured: He's definitely one of the more "refined," "cultured" characters in the series. And he's a hell of a lot more cultured than Sousuke. The thing is that, in this series, being more cultured does not necessarily make you more attractive to the opposite (or same) sex.
- Would Hit a Girl: Not only to his enemies, but not even Kaname is safe if he's angered well enough.
- Yandere: BIG TIME! By the time Kaname and Sousuke confess to each other, he's more than willing to do anything to get Kaname stay by his side and bend to his will. He's willing to slap or Mind Rape her into submission. If that wasn't enough, by the time he meets his plans, only the whispered will be aware of their new world, he wants to still have Kaname all to himself. As long as he's alive, he will never accept Sousuke and Kaname being together.
One of Amalgam's ruling hands in war affairs, with large amounts of influence and resources behind his back.
- Aristocrats Are Evil: A known politician in the Japanese power circle by day is also a ruthless top member of Amalgam.
- Greater-Scope Villain: Not only he runs up the production and manufacturing of the Codarl types, but also was the direct employer of Gauron.
- Rewarded as a Traitor Deserves: Mr. Gold spent large number of agents trying to hunt down Leonard, ignoring the minor detail that he could do the same to him.
See Mithril/Leadership for more details
An Amalgam member, and complete nutjob, Gates takes over as their primary field leader after Gauron's apparent death. Willing to murder people at the drop of a pin, Gates stands out as quite possibly the craziest character in the entire show, and concocts a series of increasingly over the top plans to eliminate Mithril.
His codename is Mr. Kalium.
- Adaptational Villainy: He was already a mean son of a bitch in the novels, where he shows the beheaded head of Yu Fan's sister to her, but in the anime adaptation he doesn't lose a single minute to prove himself as someone as evil and disgusting as Gauron.
- Arc Villain: Of the Hong Kong arc.
- Ascended Extra: Originally Gates is only known as "Mr Kalium" in the light novels and was just a mere Venom pilot who went after a rogue Xia Yu Fan, But the anime producers decided to give him more screentime, ascending to the Big Bad of the season.
- Asshole Victim: A terrible person who has the terrible luck to ran into a newly-invigorated Sousuke.
- Ax-Crazy: You get a good standpoint when even Gauron — a guy who's completely Ax Crazy himself — admits that he's a total nutcase. There's so many layers of wrong with this guy's head and haircut.
- Bad Boss: Exagerated. This guy kills his underlings for his own fuckups, and treats them as toys/punchbags, and he's also implied to sexual harras Yu Lan. As if all that wasn't enough, his psychotic breaks makes him even more dificult to handle, killing his own men over delusions
- Bestiality Is Depraved: He likes to spend his time watching videos of little animals such as kittens and squirrels, alone, in the dark, oh and with a tissue box in his hand and naked.
- Big Bad: He replaces Gauron as the main antagonist in The Second Raid.
- Beware the Silly Ones: Between his over the top hairstyle, and his even more over the top personality, you would tell this guy belongs in a comedy show and not in the battlefield. But that entertaining charm rarely eclipses a deadly hability for combat along with a cruelty to match
- Cloudcuckoolander: A dark version of this trope. For crying out loud, he randomly starts singing the Ave Maria as his men commit wholesale slaughter.
- Crouching Moron, Hidden Badass: An obvious lunatic, yet a dangerous pilot.
- Curb-Stomp Battle: His final battle with Sousuke, which sees him absolutely destroyed by the younger pilot.
- Faux Affably Evil: He's highly entertaining to watch, and can fake nice, though only for a minute or two.
- Filler Villain: Downplayed in the anime adaptation, but overall Gates has little interactions with the main characters. Though his death may have caused an impact in the series, it is never discussed.
- I Love the Dead: Talks at one point about the many, many uses for a corpse, making it very clear what he's talking about.
- Lack of Empathy: Gates treats other people as playthings or pawns and disposes of them just as quickly.
- Large Ham: He's made of ham. Singing "Ave Maria" while his underlings mass slaughter for one thing. And those wild gestures he makes while yelling out nonsensical gibberish and playacting for another."Gates has broken through! He's no mere racer; his moves are pure art! The machines are rounding the final corner! The audience is going wild!! Will he make it?! CAN HE MAKE IT?!"
- Laughably Evil: It's hard to not laugh at how utterly random his actions are.
- Law of Chromatic Superiority: Pilots a red "Venom" Codarl, the same way Gauron did.
- Leitmotif: A theme called Seppaku plays whenever he is around, and it is as strenduous as him.
- The Man Behind the Man: He backed Maress' faction in Balic and provided the Mistral-I Is and the modded Patriots loaded with ECCS warheads.
- Mummies at the Dinner Table: He likes to do this with people's corpses.
- Nightmare Face: Gates doesn't hide his excitement, and usually shows it either with this or with a big, warming Slasher Smile.
- Obi-Wan Moment: Goes from a breakdown to this before the Arbalest's lambda driver disintegrates him completely.
- Psycho for Hire: Clearly signed up with Amalgam for the killing.
- Psychopathic Manchild: His over-emotional nature combined with the sheer crazy of some of his antics makes him seem like an overexcited child — at least until you realize just what he's doing.
- Stupid Evil: His constant thirst for killing and enormous ego tends to play against him.
- The Sociopath: Exaggerated. He hits every point on the Psychopathy Checklist and then some.
- Talkative Loon: Gates never, ever shuts up.
- There Is No Kill Like Overkill: Sousuke uses his lambda driver to generate a waveforce just behind the guy whom Gates took hostage, and it completely obliterates him.
- Trigger Happy: He tends to pull the trigger before even thinking. For example, killing the man who was supposed to pay them for their goods, before even thinking of a way to get the money from him. And then immediately killing his own soldier when the soldier pointed this out.
- What the Hell Are You??: With his encounter at Nanjing, Gates defeated Sousuke with sheer lambda driver force, so it's understandable that he has a Freak Out when he sees him again, this time completely owning him.
- With Great Power Comes Great Insanity: Slightly averted; If we check his behaviour, we see two symptoms specified by Kalinin as being rooted in his use of the drug used by the A-21 terrorists (sudden memory loss and unpredictable outbursts of rage). His completely crazed love with carnage and destruction,obscure sexual tastes and acting like the world is his own personal shiny stage, though? Those are totally his.
While little is known about Gauron at the present, he is Sousuke's strongest and most formidable enemy throughout the TV series. He's a terrorist of the highest caliber sponsored by a mysterious organization, but little is known about Gauron's benefactors other than the fact that they appear to be more formidable and possess greater resources than even the notorious Soviet KGB. Believed to be Japanese, or at least of Asian ethnicity, Gauron and Sousuke have a long and bloodstained history together. Sousuke left a big scar on Gauron's forehead when he and then Soviet Spetsnaz commander Major Kalinin ambushed Gauron in a sniper attack back in Sousuke's Afghan guerrilla days. This is but one of many battle scars Sousuke inflicts upon this vicious man slayer over the course of the series.
His codename is Mr. Iron.
- Almighty Janitor: Mentioned in the novels, where Harris, another member of Amalgam, explains that with Gauron's capabilities, he could have easily become commander. However, due to Gauron's Jerkassery, most of the other members had a hard time getting along with him, and adding to that, he had incurable cancer. As a result, they decided instead to give the position to Gates, who was very much inferior.
- Anguished Declaration of Love: "I LOVE YOU KASHIM!!!"
- Animal Motifs:
- His is a lion, according to Kalinin. Languid and bored at first sight, he shows his ferocity the next second. Contrasts with Sousuke's tiger motif.
- A more symbolic and significant one might be a dragon, from his name "Gauron" (which means "nine dragons" in Chinese). And considering that Sousuke is a tiger, as well as that the dragon and tiger are natural born enemies (think Tora Dora)... well, just look at the Tiger Versus Dragon trope page. It describes their relationship perfectly. ("This refers to two spirits so wildly different and yet wildly similar at the same time, intricately linked together in destiny.")
- Ax-Crazy: As Ax-Crazy as they come. Pretty much everyone knows that he gets off on killing people. Including his associates and partners, who actually get annoyed at how he keeps killing people he shouldn't kill.
- Big Ol' Eyebrows: Pretty much has the biggest eyebrows out of every character in the series.
- Catchphrase: He loves to drawl "Baakaaa" (Idiot) to his would-be victims.
- Child Soldier: It's revealed that he's been a soldier at least since he was 12, in the Khmer Rouge. Probably even younger than that.
- Death Seeker: Which is revealed to stem from the fact that he has incurable cancer, and wants to get as much pleasure from death as he can. Extra Irony points when, the more he tries to be suicidal, the longer he seems to survive.
- Disc-One Final Boss: He's the series' biggest recurring and most dangerous villain until he is crippled at the end of the first season but he remains a threat by delegating tasks to Xia Yu Lan and Xia Yu Fan. Still, Sousuke eventually manages to catch up to him and finally kill him off, but afterwards the focus of the plot changes and Leonard Testarossa steps up as the Big Bad.
- Evil Has a Bad Sense of Humor: His comes in the form of Black Comedy.
- Evil Sounds Deep: He has a very deep voice fit for a villain.
- Faux Affably Evil: It really depends on if you appreciate his Black Comedy or not. However, by the time of The Second Raid, it's pretty clear that he is a heartless sociopath with no redeeming personal characteristics whatsoever.
- First-Name Basis: It doesn't matter who, he calls everyone by their most familiar name possible. And pretty much everyone is shown to be disturbed, creeped out, or annoyed by it. He calls Kaname "Kana-chan" (something only Kyoko, her best friend, calls her), he calls Dunnigan by the name "John" (which causes Dunnigan to get pissed off, only for Gauron to threaten Dunnigan with castration if Dunnigan doesn't let him call him that), calls Kalinin by the name "Ivan" (something no one else calls him)... and then there's the pet names he has for poor Sousuke.
- For the Evulz: His main reason for doing most things, really. Including betraying and killing his employers for no real reason.
- Go Out with a Smile: He had a very happy smile on when he died.
- Green-Eyed Monster: Lord help anyone else that gets too close to Sousuke.
- Hey, You!: Being the rude jerkass he is, he has a habit of doing this to everyone. See also First-Name Basis.
- I Love the Dead: Something he shares in common with Gates.
- In Love with Your Carnage: This is the reason that this guy is so utterly obsessed with Sousuke — when he first met him at 12 years old, Gauron saw something in the boy's eyes; an ice-blue will to kill, without sin or care. He spends much of the series trying to "reawaken" this side of him.
- I Surrender, Suckers: What he pulls off on Mithril as part of his plan to take over the Tuatha De Dannan.
- Knife Nut: It's revealed that Gauron's Weapon of Choice and specialty is knives.
- Knight of Cerebus: Whenever he's around, the joking stops.
- Large Ham: The guy manages to make everything he does hammy. Especially by including Evil Laughter after saying anything. In the novels, he even literally eats ham while dramatically giving orders to the AI on the Tuatha de Dannan.
- Law of Chromatic Superiority: Gauron's first two Codarl models were silver and were portrayed as far more dangerous than the usual dull grey AS. His final one was a blood red "Venom" model, which was portrayed as still more deadly than the basic Codarl.
- Love at First Sight: Apparently what he felt when he first saw 12-year-old Sousuke. He was immediately so smitten with Sousuke that he literally took a double look, immediately parked his jeep, and attempted to get Sousuke to come with him. Four years after being rebuffed and never seeing Sousuke again, he actually manages to recognize Sousuke as soon as he gets a clear view of his face. Scary.
- Love Is a Weakness: Gauron angrily tells Sousuke that, ever since the boy fell in love, he's become weaker, more messed up, and has a bunch of conflicting feelings.
- A Love to Dismember: His infamous (and thankfully unfulfilled) desire to rape Sousuke's corpse after killing him.
- Manipulative Bastard: He certainly managed to manipulate the two twins he took in and raised into falling in love with him and doing anything he bids them to. And then he managed to manipulate and piss Sousuke off to the point where he finally managed to get the death he always wanted, killed by the Assassin Saint he always loved.
- Murder the Hypotenuse: His unreasonable anger and and jealous grudge against Kaname is explained in TSR, where it's explained that he wants her dead because Sousuke likes her. Yep, his main reason for ordering the two twins he raised to tail her was because he wanted the girl who managed to "tame" his beautiful Assassin Saint to die, so Sousuke will revert back to his emotionless, violent self.
- No One Could Survive That!: Which he continues to pull off around maybe... 5-6 times in the series. Each incident getting increasingly ridiculous as to how he could possibly survive.
- No Sense of Personal Space: Directly Lampshaded in the novels, where numerous victims of his note his smug way of breaching on people's personal space.
- Pædo Hunt: Gauron's been after Sousuke ever since the latter was twelve years old. And the things he wants to do to the boy are very, very creepy.
- Pick on Someone Your Own Size: He takes this to illogical extremes with Sousuke. What exactly did the boy do to deserve his obsessive stalking and persistent attempts to make his life miserable?
- Psychotic Smirk: His default expression. Only changed when he's having his Slasher Smile.
- Silver Fox: He's really muscular and well built for his age, as is made really obvious.
- Smug Super: Despite possessing hubris in abundance, he truly is an unstoppable force on the battlefield. With the exception of Sousuke Sagara, none of the soldiers of Mithril can hold a candle to his abilities as an Arm Slave pilot. Perhaps most significantly, he has consistently demonstrated an almost supernatural ability to cheat certain death right up until the moment he drove Sousuke to help him commit suicide.
- Stalker with a Crush: If there's anyone that acts like one in this series, it's him. Especially toward Sousuke, who would much prefer he leave him the hell alone.
- Taking You with Me: What he tries to do with Sousuke at the end of season 1. He also takes the opportunity to dramatically confess his love for Sousuke, which sort of falls flat when Sousuke blasts him off off the ship so only Gauron's AS explodes.
- Would Hit a Girl: Shouldn't be a surprise, but it's there. During the hijacking, he would have killed the high school teacher if Sousuke hadn't distracted him — then when he takes over the Tuatha De Danann (and after Tessa let Kaname escape), he does not hesitate to viciously yank on Tessa's ponytail, or use her head as a foot-rest.
- Yandere: Way over the "psychotically crazy" side. However, the fact that he managed to raise twins and succeed in Wife Husbandry means something.
An Amalgam agent brought to Tokyo to work with Leonard and continue where Gauron and Gates failed.
- Ambiguously Brown: The light novels describe him as "having one of those ambiguous ethnicities, a face that could be anything from Latino to East Asian."
- Bad Guys Do the Dirty Work: He kidnaps the entire Jindai school and surrounds it with explosives to get what he wants.
- Badass Longcoat: Kurama uses a black trencoat that deflects bullets like Leonard has.
- Expy: Of Jean Reno's character in The Professional.
- Even Evil Has Standards: Kurama does no more and no less than his job. He hates the idea of killing children and is not a fan of gratuitous slaughter. That being said, though he would feel horrible about it later, when he is on his job mode, he disposes of this trope by doing ANYTHING that does the job
- Four Eyes, Zero Soul: And not just normal glasses, but ones with black lenses!.
- Hero Killer: Kills some DGSE AD commandos in Namsac and nearly killed Sousuke if Lemon's team didn't move in.
- One Last Smoke: Well, fuck. Since he stopped smoking all he gets are carrot sticks. Before dying he laments not having a chance to use this trope.
- Smoking Is Cool: Averted, he stopped smoking not long ago and replaces it with carrot sticks. Nonetheless, he is a badass.
- Villain's Dying Grace: After being mortally wounded by Sousuke, he asks him where Kaname might be. At first he denies him the satisfaction, but shortly after has a last change of heart by telling him where she is before passing away.
- We ARE Struggling Together: He really doesn't like or trust Leonard, but he has to work with him since he is an invaluable asset in Amalgam.
- Weapon of Choice: Uses a Jericho 941 as his sidearm of choice.
- Western Terrorists: An implied European terrorist who conducts a terror campaign in Chofu just to get Sousuke and Kaname.
- Would Hurt a Child: He openly admits that this is the worst part of his job, but he isn't bluffing when he almost blows an entire school and shoots Nami dead in cold blood.
One of Leonard's subordinates. He pilots an Eligor, a Lambda Driver equipped Arm Slave visually identical to the "Venom" type Codarl.
One of Leonard's subordinates, as well as Kurz's former sniping mentor. He pilots an Eligor.
One of Leonard's subordinates from Poland. She pilots an Eligor. Sabina has reservations on bringing Kaname in.
Two Chinese male twins recruited by Gauron prior to the events of Hong Kong.
- Replacement Goldfish: A possible interpretation of their devotion to Gauron, being the replacement for Sousuke after he left Afghanistan.
Xia Yu Fan and Xia Yu Lan
- Anime Chinese Girls: Complete with all the stereotypes. Yu Lan, at one point, wears her hair in the Odango hairstyle and a Qipao. Both are shown to be very adept at martial arts and using knives, and they even have the accent when attempting to pronounce "Chidori" (instead using the Mandarin pronunciation, "Chinniu").
- Big Sister Instinct: When Gates taunts her with Yu Lan's lifeless body, Yu Fan completely loses it and betrays her boss by attacking him.
- Creepy Twins: Murderous twins who finish one another's sentences.
- Decoy Damsel: Yu Lan, who pretended to be one of the kidnapped hostages. She played the part pretty well, giving the Mithril agent who untied her an appreciative, admiring look. And the guy definitely looks very self satisfied that he had rescued a pretty Damsel in Distress... until she slits his throat immediately afterward.
- Dull Eyes of Unhappiness: Mao notes the 'despair eyes' of Yu Lan as she's trying to hack her up with a machete.
- Elegant Gothic Lolita: The Sigma versions of the twins dress like this.
- Evil Counterpart: The twins serve as mirror images to Sousuke, being stoic teenage mercenaries who were adopted and cared for at a young age by a seasoned soldier. Unfortunately for the twins, the soldier they were raised by was Gauron. To further contrast with Sousuke, a Chaste Hero uncomfortable with sexual situations or with being touched, the twins are shown to being willing to use their sexuality as efficiently as machetes or firearms... and occasionally as a precursor TO those weapons.
- Gender Flip: In the novels, they were actually male. Whereas, in the anime they are female.
- Happiness in Slavery: Despite Gauron caring little for their wellbeing, their only happiness seems to come from being together with him. They're shown to be so incredibly depressed when they find out he's dying, and the only thing that gives them temporary comfort is that they are reunited with him.
- Hero Killer: They had a hand in killing Tony and his fellow PRT operators and Mao would have been killed if the SRT didn't intervene in time.
- Knife Nut: Since Gauron's specialty is in knives, he apparently taught it to Yu Lan as well. She's shown to be very skillful and graceful wielding two large knives during her fight with Mao.
- Law of Chromatic Superiority: Yu Fan pilots a black painted Shadow, and easily the most dangerous enemy on the field after Gates.
- Odango Hair: The hairstyle Yu Lan wears during a mission.
- Original Character: They only appear in The Second Raid.
- Show Some Leg: What they did to some of the Amalgam engineers, in order to distract them and carry out their Sensei's plan. Yu Fan kisses one of the men, while Yu Lan... apparently jacks one of them off.
- Single-Minded Twins: They can even finish each other's sentences.
- Wife Husbandry: Implied to be what Gauron very successfully executed with them. Although he failed in his attempt with Sousuke, he managed to get his hands on these two, and certainly managed to make them fall very much in love with him.
The two young European assassins working under Gauron. They only appear in the Sigma manga version.
- The Infiltration: Julie was seen chasing Sousuke and the others after they snatched Bruno from Sicily in a Rk-92 Savage, working as a Sicilian mobster-hired AS pilot.
A former friend of Sousuke's from their time as guerillas in Afghanistan, Zaied served as something of a mentor to the younger Child Soldier, and the two of them grew closer than brothers. While Sousuke and several others were away from camp, Zaied and the other guerillas were apparently killed in a raid by Gauron's mercenaries. Sousuke does encounter Zaied again though, during the "Wind Blows At Home" arc. Zaied is revealed to have survived, and is now on Gauron's payroll.
- Big Brother Mentor: In the Backstory. He was the other child in Sosuke's guerilla group and acted as a mentor figure to him.
- Broken Pedestal: A mild version of this. Not that Sousuke really worshipped him or felt so eternally grateful to him... but Zaied was a respected memory to Sousuke of an honorable, dead comrade of the past. Needless to say, any feeling of goodwill on Sousuke's part completely vanishes when he realizes that Zaied decided to team up with Gauron and kill a bunch of his current comrades.
- Child Soldier: Played frighteningly straight. Sousuke may be raised by the KGB and have No Social Skills but Zaied is too screwed up for words. His experiences have left him with the impression that winning is all there is to war, and that it doesn't matter what side you're on as long as you are victorious. He's been like this since he was at least twelve.
- The Dragon: Serves as Gauron's during the "Wind Blows At Home Arc". He's the latter's second-in-command and is the group's best pilot after him, is a Foil to The Hero, and has to be defeated by Sousuke before he can engage in combat with Gauron.
- Empty Shell: Is there anything left inside Zaied? He generally comes off as a dead man walking.
- Evil Counterpart: Chillingly demonstrates what a few more years of warfare could have turned Sousuke into. Zaied plays the whole Child Soldier thing very straight as opposed to Sousuke's more humorous portrayal, and takes every one of the tropes associated with Sousuke to their worst possible extreme. Sousuke's repressed, Zaied's emotionless. Sousuke's a Combat Pragmatist, Zaied will do anything to win. Sousuke hates Gauron, Zaied seems to be using him as a reference to get into Amalgam. He even serves as Gauron's guide to the local area, directly mimicking Sousuke's role with the Mitrhil team.
- Evil Former Friend: A one-time comrade and friend of Sosuke's.
- Fallen Hero: An anti-Soviet guerrilla turned Amalgam agent under Gauron's employ.
- Forgotten Friend, New Foe: Not so much "forgotten" as "thought he was dead" but the results are about the same. Unlike many examples, they don't get over it either, or even really address their issues, but spend all three of Zaied's episodes trying to murder one another in the most brutal fashion possible.
- Gatling Good: Uses one as his Arm Slave's primary weapon.
- Hired Guns: Appears to have become a mercenary since the destruction of his old guerilla cell. The episode implies that he is seeking Gauron's assistance in applying for Amalgam membership.
- It's All About Me: Preemptively betrayed his guerilla cell in order to ensure his own survival, and didn't care if his only friend died in the process.
- Lack of Empathy: It's pretty easy to see him as an emotionless sociopath. He doesn't bat an eye while committing atrocities or trying to kill his former friend, has no problem working for the man who murdered his comrades, and betrayed his all his friends just so he could "be on the winning side". Not to mention that he's emotionally a corpse, and willingly transports nuclear weapons in exchange for a paycheck.
- Last Breath Bullet: Subverted. He unexpectedly still had enough life to be able to aim his gun at Sousuke and tell Sousuke that the person who has remaining ammunition is the winner. Sousuke is shown wincing and waiting for the impact, but instead Zaied falls back in his seat and opens fire into the air (whether this was involuntary or deliberate is up for debate).
- Law of Chromatic Superiority: Pilots a blood-red Shadow Arm Slave, in comparison to the rest of his troops in their tans and greys. His Arm-Slave, the first Shadow to appear in series, is actually the precursor to Gauron's own similarly coloured Venom suit.
- More Dakka: And lectures Sousuke on the need to keep additional bullets so that this tactic is workable.
- Never Found the Body: Apparently, Sousuke didn't even bother really looking for his body before putting a flag marker grave in honor of him. So much for that...
- Not a Game: All that matters to Zaied is winning and he treats life as one big game.
- Not Quite Dead: And nearly manages to take Sousuke with him before expiring.
- Scars Are Forever: The scar under his left eye.
- Shell-Shocked Veteran: To the point where trauma has destroyed his ability to feel empathy.
- Sociopathic Soldier: Of the shell-shocked variety. Zaied is broken and he'll break anyone else who comes his way.
- The Stoic: But unlike Sousuke, who's simply repressing his feelings, Zaied is legitimately dead inside. He has essentially no emotion to speak of.
- Tempting Fate: He tells Gauron: "I've seen a lot of idiots die because of their stupid ideas of love and friendship. I'll never be like that." after Gauron (justifiably) makes sure that Zaied won't go easy on Sousuke. Next episode: Zaied ends up sparing Sousuke, as he's unable to bring himself to shoot Sousuke with his remaining ammunition—though whether this was an act of mercy or the result of expiring before he could pull the trigger is up for debate.
- Turncoat: Betrayed his and Sousuke's guerilla cell to Gauron's mercenaries, because he was more concerned with winning than the cause he was fighting for.
Formerly an Arm Slave pilot for MITHRIL, he managed to survive the blitzkrieg by Amalgam and defected to their side.
- All Your Base Are Belong to Us: His home base in the Mediterranean Fleet was attacked and conquered by Amalgam forces while he was away on mission. When he returned, he found himself cut off and surrounded by vastly numerically (and likely technologically as well) superior forces.
- FaceHeel Turn: A rare quasi-sympathetic example, in that his choices were "join Amalgam" or "die".
- Foil: George is what Sousuke would be if he choose to live his current life post-Mithril without seeing the need to reunite with his comrades at the TDD-1 or rescue Kaname.
- Punch-Clock Villain/Punch-Clock Hero: Nominally considered a 'hero' while working for the good-aligned Mithril, the fact stood that he was still a mercenary first and wasn't willing to stick with a side that seemed to be losing.
- Rock Beats Laser: Literal and metaphorical example. When pitted against Sousuke's archaic Rk-92 Savage in a cutting-edge M9, he loses after a protracted battle. And he loses because Sousuke caved in a ruined temple on them both.
- Spell My Name with an "S": His name used to be translated as "Luvruck" before Invisible Victory settled on Lovelock.
