History Characters / MobileSuitGundamIronBloodedOrphansTekkadan

* {{Expy}}: Many of the characters within Tekkadan can easily be seen as parallels to the marooned British Schoolboys from 1954's ''Literature/LordOfTheFlies''.

* FailureHero: They become this in Season 2. Once Rustal starts moving against them, they either lose, something goes wrong, or they “win” at [[PyrricVictory a massive cost]]. By the end, [[spoiler:Rustal [[TheBadGuyWins completely crushes them]], successfully blames all his crimes on them, and only lets the survivors live happy lives because they post no threat to him anymore; and to add insult to injury, HE implements the reforms they wanted and grants Mars independence, in a manner that basically forces Kudelia to work with the very man who orchestrated the deaths of nearly everyone she loved]].

* DeadlyDeferredConversation: He was going to talk to Orga about leaving Tekkadan after their defensive mission in episode 21. Of course, Biscuit doesn't survive the operation. [[spoiler: Mikazuki informed Orga that he had his own conversation with Biscuit beforehand, and Biscuit had decided he wasn't going to leave Tekkadan. This helped give Orga his HeroicSecondWind for the end of Season 1.]]

* HeroicSacrifice: [[spoiler: During the battle against Carta's forces in Episode 21, he pilots a mobile worker that Orga stands on top of to give his commands across the battlefield. When Carta figures out which mobile worker Orga is on, she goes after it. Biscuit hurls Orga overboard and acts as a decoy, ultimately costing Biscuit his life.]]

* MoralityChain: [[spoiler: His death was the point where Tekkadan stopped fighting for simple survival and started fighting to crush their enemies.]]

* NonActionGuy: Though he does have an Alaya-Vijnana implant and can pilot a Mobile Worker, he's not one of Tekkadan's regular combat pilots. Instead, he takes a support role, acting as Orga's staff officer. [[spoiler: The one time he participates in battle is when he gets killed.]]

* TeamMom: Closest they have to one, at any rate.

* PeekABangs: His hairstyle covers one eye, reflecting his shyness. [[spoiler:In the epilogue, he is shown to have changed to a more swept-back hairstyle.]]

* BecameTheirOwnAntithesis: While well-meaning, with Tekkadan becoming something of a safe harbor for other Human Debris and disenfranchised children, the Organization ironically has the opposite effect on the society around them. Their actions throughout the first season encourage armed forces to use ''more'' Human Debris because Tekkadan ironically proved their usefulness. This comes full circle in TheGrandFinale where [[spoiler: Tekkadan ends up becoming the cautionary tale of Human Debris and ChildSoldiers as a whole, and it was through their destruction that society finally started to do away with the system]].

This comes full circle in the Grand Finale where [[spoiler: Tekkadan ends up becoming the cautionary tale of Human Debris and Child Soldiers as a whole, and it was through their destruction that society finally started to do away with the system]].

* HundredPercentAdorationRating: By season 2, nearly all of Tekkadan has UndyingLoyalty to him. [[spoiler:To the point when he dies, half of Tekkadan are willing to die in a RoaringRampageOfRevenge even through Orga's final order was for them to live. Years later, Ride and several others assassinate Nobliss and his men in revenge of Orga's death despite the potential consequences.]]

An employee of the main Teiwaz branch (rather than any of the subsidiaries, like the Turbines), she joins the crew of the ''Isaribi'' after Tekkadan is inducted into Teiwaz. She acts as a liaison to Teiwaz and a general adviser to Tekkadan, particularly Orga. In season 2, [[spoiler: following the death of Jasley, Merribit resigns from Teiwaz and joins Tekkadan full-time.]]

She acts as a liaison to Teiwaz and a general adviser to Tekkadan, particularly Orga. In season 2, [[spoiler: following the death of Jasley, Merribit resigns from Teiwaz and jonis Tekkadan full-time.]]

* HeroicBuild: Come season 2, and while he is not massive, [[https://www.deviantart.com/francis526/art/Takaki-Uno-Mobile-Suit-Gundam-1-944468983 he is very defined]].

* RoaringRampageOfRevenge: While he never goes to the extents that Mikazuki does, Akihiro is a firm believer in paying those who harmed his friends back twice as full. [[spoiler: Galan Moss and Iok Kujan both experienced rather brutal deaths this way.]]

* AintTooProudToBeg: [[spoiler: Orga offers his life to Rustal if it means sparing the rest of Tekkadan from Gjallarhorn's retribution. Unfortunately, Rustal is not having any of that.]]
* AlmostDeadGuy: [[spoiler: He manages to give Ride and Chad a FinalSpeech of encouragement and starts walking quite a distance before bleeding to death.]]

* FatalFlaw: Orga's ambitions is both his greatest strength and weakness. He wants society to recognize and respect Tekkadan's strength, but for every step he takes to reach his goal, Orga puts [[TheChainsOfCommanding both himself and the rest of Tekkadan at risk]]. Season 1 didn't have any problems with this, but season 2 is where Orga's ambitions start interfering with his judgment, albeit in minor ways. When [=McGillis=] offered to give Tekkadan complete control over Mars if his Gjallarhorn reforms succeed, Orga accepted the offer. While most of Tekkadan follow him without question, Takaki quits because he already has a good life on Earth with his sister and doesn't want to risk losing it. At the same time, Naze tells Orga some of the higher-ups at Teiwaz see Tekkadan as opportunistic upstarts, and if Tekkadan and Teiwaz ever come to blows, he will have to side with Teiwaz. [[spoiler: Before his death, he realizes his real goal was not to reach someplace where Tekkadan could be happy, but to give his friends the opportunity to achieve their own dreams.]]

* HeroicBSOD: In the aftermath of [[spoiler: Biscuit's death]], Orga shuts himself inside his room and sulks until Mika [[GetAHoldOfYourselfMan convinces him to leave.]]

* HundredPercentAdorationRating: By season 2, nearly all of Tekkadan has UndyingLoyalty to him. [[spoiler: To the point when he dies, half of Tekkadan are willing to die in a RoaringRampageOfRevenge even through Orga's final order was for them to live. Years later, Ride and several others assassinate Nobliss and his men in revenge of Orga's death despite the potential consequences.]]

* SacrificialLion: [[spoiler: Killed two episodes before the finale just to show Gjallarhorn is done playing nice.]]
* ScrewTheMoneyIHaveRules: [[spoiler:Jasley]] tries to pay Orga not to kill him. But as far as Orga's concerned, [[spoiler: Jasley]] killed too many people Tekkdan cared about for the vendetta to end in anything but blood.
* SecretlySelfish: This is brought up in episode 38 by Naze. [[spoiler: He thinks that Orga's desire to be King of Mars might not just be for his family but a desire to finish his work and finally take a break. And Orga begrudgingly admits that it might be true.]]
* SingleTear: [[spoiler: His reaction when he learned that Naze did die in episode 40.]]

* DyingMomentOfAwesome: [[spoiler: In the final episode, Akihiro is weakened and beaten from a railgun assault by Rustal's forces and is about to receive a fatal blow from Iok Kujan, until he hears the latter's name and wills himself to kill him before dropping dead.]]

* ObliviousToLove: [[spoiler: Completely oblivious to the fact that Lafter is falling for him. This is despite everyone else starting to pick up on it.]]

* TakingYouWithMe: [[spoiler: Dies while managing to crush Iok alive]].

** Against "Galan Mossa", [[spoiler:after Aston dies]].

* NumberTwo: In Season 2, Eugene is the Deputy Boss of Tekkadan. [[spoiler: He seems to have become Kudelia's main aide in the epilogue.]]

* TheBigGuy: Even bigger than Shino, Akihiro, or Nadi.

* RewardedAsATraitorDeserves: [[spoiler: After betraying Tekaden to Galan, he gets abandoned to his fate. Which eventually is getting executed by a vengeful Takaki.]]

* AbsurdlyYouthfulFather: [[spoiler: Gets Atra pregnant while they're both teenagers, and becomes a father [[SomeoneToRememberHimBy posthumously]].]]
* AcePilot: He's the best pilot in the Third Group, which is why Orga taps him for the job of piloting the Barbatos. Like most Gundam protagonists, he's a classic Steamroller, focusing on taking down his enemies with maximum speed and aggression.
* AchillesPowerCord: [[spoiler: Mikazuki can use the right side of his body if he's linked with the Gundam Barbatos, but that limits how far he can move away while retaining full control of his entire body]].
* ActionHero: A ''[[SociopathicHero very dark]]'' example of the trope. He's a [[UnscrupulousHero ruthless soldier]] in which Orga is the only one making sure Mikazuki is a hero, but whenever he enters the battlefield, it's clear the situation can no longer be solved peacefully.
* AdmiringTheAbomination: [[spoiler: His reaction to the Mobile Armor is that it's beautiful.]]
* AffectionateNickname: The people close to him call him Mika.
* AnArmAndALeg: [[spoiler: Suffers a downplayed version by losing the use of his right arm and eye in the battle at the end of Season 1, and by Season 2 episode 13, his right leg as well, though they are still attached to him. Now he says he can only use them while connected to Barbatos. So far, he seems to be right about it. It's not confirmed if he legitimately cannot use them outside of the Gundam or if he simply ''thinks'' he can't, which in turn prevents him from doing so. However, everything on the right side is fully usable once linked up with Gundam Barbatos (even an umbilical cable can do the job, letting him linger outside the machine) so we know they aren't ''dead''. They may simply have some form of mental block on them that Mikazuki doesn't understand (or care about), and simply works as best he can around them.]]
** [[spoiler:According to the side material the issue is that overuse of the AV system causes parts of his brain and nervous system to become dependant on it to function, hence why they work but only if he's connected to Barbatos and using the system. This might not necesserily be permanent but Mikazuki certainly isn't going to get any better still using Barbatos all the time and nobody really has the knowledge on how to repair that kind of damage anymore. Given that Gjallarhorn's founders were all Gundam pilots who regularly overclocked the system to fight mobile armors and didn't seem to share this problem, it's likely there IS some cure but Tekkadan obviously would never be in a position to find it]]
* AnimalMotifs: Barbatos goes motifs 3 times, first from a mobile suit with a slight goat motif (from it's namesake), to a Wolf as the Lupus (it's even in the name), to a wolf/large dinosaur hybrid as the Barbatos Lupus Rex ("King of Wolves", as [=McGillis=] calls it), each upgrade making it become progressively more demonic than it was initially. [[spoiler: The Barbatos even howls during its final battle]].
* AntiHero: A protagonist who mostly just does what he's told and has a chilling lack of mercy for opponents, but who nonetheless fights in service of his Tekkadan family and Kudelia's noble cause.
* ArmCannon: The Barbatos's 'fifth form', designed to counter the Kimaris, is fitted with a pair of two-shot rocket launchers beneath its forearms. When it reaches Earth, these are replaced with a pair of short-barrelled 170mm cannons, finally giving the Gundam a ranged option that doesn't compromise Mikazuki's CloseRangeCombatant fighting style.
** In Season 2, the Barbatos Lupus has a pair of 200mm guns mounted on its arms. The Barbatos Lupus Rex also has the same 200mm guns built into its ginormous forearms.
* AttackDrone: The Barbatos Lupus Rex has by far the simplest example in the franchise so far: a bit blade mounted on a tail-like extension on the back that was inherited from the Hashmal. It's connected to the Gundam by a flexible cable, and Mika makes damn good use of it in Season 2. See BewareMyStingerTail below.
* BackToBackBadasses: [[spoiler: In the final episode, he and Akihiro stand back to back against the Arianrhod Fleet. Also counts as a DyingMomentOfAwesome. ]]
* BeastAndBeauty: Along with his [[LadyAndKnight Knight/Lady]] dynamic with Kudelia and even to [[HoYay Orga]], there are definitely shades of this given that he is referred to as a "monster" or even a "devil" in his machine.
* BewareMyStingerTail: After it was rebuilt, Mikazukis' Mobile Suit ASW-G-08 Gundam Barbatos Lupus Rex now comes equipped with Hashmals' Wire Blade that Mika can control.
* {{BFG}}: In a sharp contrast to most mobile suit guns, which are designed for mowing down tanks and infantry because of the difficulty in getting through larger targets' tough nanolaminate armour, the Barbatos's primary ranged weapon is a gigantic, suit-killing howitzer. It's still not immensely effective, but you really don't want to be on the receiving end of [[NoRangeLikePointBlankRange a point-blank shot from it]], as one unlucky pilot found out the hard way.
* {{BFS}}: Downplayed. As part of its MidSeasonUpgrade from Teiwaz's engineers, his Barbatos gets an odachi almost as tall as the suit itself... but compared to the gigantic mace that was its previous melee weapon of choice, it looks positively delicate. The Lupus's 'sword mace' is a more conventional example, essentially a massive bar of metal with an edge, a point, and a handle that's as much bludgeon as blade. [[spoiler: When he's confronting the Hashmal, Mika borrows Helmwige Reincar Greatsword from Isurugi and uses it to impale Hashmal.]]
* BigEater: One thing he has in common with most Tekkadan kids, which might be justified by the [[BadBoss CGS adults]] starving them on occasion. One major difference is his ability to seemingly [[PintsizedPowerhouse metabolize it all directly into strength.]]
* BiggerIsBetter: His Barbatos's twin reactors make it strong enough to effortlessly wield weapons that are huge even by mobile suit standards, and Tekkadan's engineers are only too happy to provide them.
* BiggerStick: It's normal for a Gundam protagonist's suit to be one of the most powerful in the setting, usually as a way to offset the inexperience you'd expect from a KidHero, and the Barbatos is no exception, even if it is somewhat in need of maintenance at first. Mika, meanwhile, is part of that rare and fearsome subset who ''also'' know how to wield their BiggerStick with deadly effect, making him one of the most dangerous people in the solar system almost from day one.
* BigBrotherWorship: Treats Orga as if he were an older brother, one whom he admires more than anyone else.
* BigDamnHeroes: Several times in the series. So far...
** for the First season: episodes 1, 9 & 24.
** for the Second season: episodes 7, 11 & 12.
* BigOlEyebrows: Mika's thick eyebrows accent his frank and serious nature, especially when he looks at you with that poker face while his eyes stare into your soul.
* BlackAndWhiteInsanity: Not to the extent of [[Anime/MobileSuitGundamSEEDDestiny Shinn Asuka]] but it's the larger principle that matters. Mika categorizes the world into two ways: allies to be protected and enemies to be destroyed. In his mind, if you're in Orga's way, get out or die.
* BloodKnight: Kudal accuses him of enjoying killing people, an accusation that ''mildly'' disturbs Mika.
* BrainComputerInterface: Like all the primary combatants of the Third Group, Mikazuki has the Ālaya-Vijñāna system to directly link him to the machines he pilots. ''Unlike'' the rest of the Third Group, the link to the Barbatos is ''required'' to operate it, rather than just enhancing his skill with it. It uploads data directly to his mind, including giving him a first person view of what the Gundam sees. The procedure for getting the Ālaya-Vijñāna requires surgically-implanting and fusing the connecting nerve into the spinal column; which has a high mortality rate during the implantation process: even during subsequent implantations. Mika is the only one in the entire show that has THREE "whiskers" implanted in his back.
* BrutalHonesty: As long as you're not his enemy you don't have to be afraid of him, but he's not one for social tact -- often very blunt and straight-to-the point when he has to say something.
* BondOneLiner: "Shut up, I can't hear Orga's words."
* ButForMeItWasTuesday: In episode 25, Ein is raging at Mikazuki for killing [[StarterVillain Lieutenant Crank]], an event which Ein is obsessed with avenging by killing Mikazuki and the rest of Tekkadan, and even led him to [[spoiler: allow himself to be wired into the Graze Ein to do it]]. Mikazuki's response is "Who the hell is Lieutenant Crank?" Ein is ''not'' pleased by this.
* CallToAgriculture: One of the first indications that there's more to him than being an emotionless killing machine is when he says that he'd like to become a farmer someday. He's quite happy to help Biscuit's family work on ''their'' farm in the meantime. Unfortunately, after his battle with Hashmal, [[DreamCrushingHandicap that's no longer an option.]]
* CarryABigStick: When they first start to use it, Gundam Barbatos' primary weapon is an enormous (even by mecha standards) flanged mace. Once Tekkadan finally arrives on Earth, it's replaced with something even more nightmarish - a giant club that can fold out into a chainsaw-toothed pincer, letting it literally bite through enemy suits. Season 2 has the Lupus carry a hybrid sword-mace that manages to be even larger than both of its prior armaments. The Lupus Rex returns to form with a new mace similar to the Barbatos' first one...but ''even bigger''.
* ChainsawGood: The Barbatos's sixth form has one of these as its main weapon - a strange, fearsome-looking club-claw with a chainsaw serving as the 'teeth' of its 'jaws'.
* CharacterDevelopment: While he is one of the more static characters in the show, he goes through some subtle but important development in learning about interpersonal relationships and [[spoiler: falling in love]].
* ChickMagnet: Downplayed--he only has two girls interested in him--but it's still remarkable that he got both Kudelia and Atra interested in him at the same time just by being himself, without any conscious effort.
* ChildhoodFriends: With both Orga and Atra.
* ChildrenForcedToKill: It hasn't been expanded on - yet - but some brief flashbacks imply this about his early life.
* ChildSoldier: His exact age isn't clear, but he seems to be on the young side (even by the Third Group's standards) for a combat pilot, despite his skill.
* CloseRangeCombatant: Guns are largely useless against the nanolaminate armour used by anything big enough to mount an Ahab Reactor (so, ships and mobile suits), which means most suits carry them to deal with smaller targets like shuttles, tanks, and infantry. Since Tekkadan uses Mikazuki as their dedicated mobile suit killer, that's not a concern - his job is to close with enemy suits as fast as possible and rip them apart, and he often doesn't go into battle with any ranged weapons at all, even when they're readily available.
* CluelessChickMagnet: Despite his ShipTease with Kudelia and Atra, Mika has a very limited understanding of romance (and basic socialization in general), and is completely unaware of the potential threesome Atra is pushing him towards. [[spoiler: By episode 41 he seems to have caught on to Atra's hints, and he and Atra make Kudelia an equal partner in their relationship in episode 47.]]
* CombatPragmatist: He fights to ''win'', with no qualms about "dirty" tactics like sneak-attacking from ambush, using enemy units as shields, and using clouds of dust or smoke to blind opponents. He also has no qualm with aiming directly for the cockpits of enemy units the moment he has a chance to.
* CombatStilettos: The Barbatos is given stiletto style feet when optimized for Earth's gravity (despite the fact that would make its balance worse). Its upgrades, the Barbatos Lupus and Lupus Rex are built with even larger stiletto feet, the latter [[AllThereInTheManual stated]] to contain {{Pile Bunker}}s.
* ContrastingSequelMainCharacter:
** Compared to the NiceGuy [[Anime/GundamReconguistaInG Bellri Zenam]] Mikazuki seems like a huge jerk. At first. His HiddenDepths slowly come out from below that blunt, brutally honest exterior.
** Mikazuki also contrasts previous stoic protagonists [[Anime/MobileSuitGundamWing Heero Yuy]] and [[Anime/MobileSuitGundam00 Setsuna F Seiei]]. Heero and Setsuna both had solid education and at least a cursory understanding of politics; Mikazuki has none - he can't even read and even after Kudelia teaches him he's still disinterested in the wider background apart from protecting his Tekkadan brothers. Heero and Setsuna both move away from their horrendous ChildSoldier pasts towards a better future and become better people by finding their inner understanding; Mikazuki never truly manages to reconcile with his past (due to his close connection to Orga, Orga's descent into delusion in season 2 disrupts any chance of Mika truly understanding what is the reason to fight for).
* ConvenientlyAnOrphan: With no other family, he's fiercely loyal to Tekkadan.
* CooldownHug:
** Received one from Kudelia in Episode 13, to which he repays with a kiss out of nowhere.
** Gives one in episode 18 to ''both'' Kudelia (upon Atra's persuasion) ''and'' Atra (upon noticing that she was crying as well).
** Ends up ''again'' at the receiving end of this in the Season 1 Finale, but this time with a double head pat from ''both of them''. Though the positioning tends to lean more over ALadyOnEachArm.
** Gives another one to Atra [[spoiler:in episode 44, after the latter breaks down out of worry after having given an AnguishedDeclarationOfLove.]]
* CovertPervert: Mika starts off knowing very little about sex or babies because of his upbringing, and seems to react with detatched curiosity when such things are explained to him; much of the time it seems to Kudelia and Atra that he doesn't look at them in a romantic or sexual way. Yet every once in a while, he does something unexpectedly forward showing he ''has'' been thinking about what he's learned: Kudelia is caught off guard in episode 13 when he [[spoiler:kisses her and calls her cute]], while a flustered Atra has to excuse herself to calm down and think things over after he [[spoiler:suggests making babies together]] in episode 41. And that is topped in episode 47 [[spoiler: when Atra suggests a {{Polyamory}} option that would make both her and Kudelia his girlfriends, which Mika accepts immediately. It would have lead to a MarryThemAll ending had Mika not perished in the finale]].
* CreepyChild: There are times when he seems to be... rather off, even by the standards of Gundam ChildSoldier main charactrs. The most unsettling thing about him is the fact that, with very few exceptions, he remains [[TheStoic calm and emotionless]] at all times.
* CreepyGood: He's the main character of the series. He's also scary as hell.
* DealWithTheDevil: With Barbatos, of all things. [[spoiler:Barbatos is mentioned as an ambiguously sentient machine, but during the final episode, Mika asked for extra power to take on the Graze Ein, and he got it at the cost of his right arm and right eye while not in Barbatos. Considering the name is taken from ''Literature/ArsGoetia'', you can easily see it as Mika summoning a demon to help him defeat his enemy, who then took his arm and eye as payment. The fact that Mika could only use his eye and arm while connected to Barbatos further reinforce the image that 'the arm and eye are still there, they just don't ''belong'' to you anymore'. Even more disturbingly, his right eye activated WHEN NOT CONNECTED TO BARBATOS upon the reactivation of the buried autonomous Mobile Armor that Tekkadan found. In this setting, the Gundams were created specifically to destroy the Mobile Armors, making it look as if the Barbatos was looking through Mika's eye upon sensing an old enemy reawakening.]]
* DeathSeeker:
** A variant. [[spoiler: He's a barely-literate child with virtually zero marketable skills other than his ability to kill people. Someone he trusts and respects plans to end all war. He's put two and two together, and no longer sees any value in his own life, because he believes he'll no longer be useful for anyone when the dust settles. Especially obvious after he loses the ability to use his right leg which, coupled with the similar disability of his right arm, leaves him unable to walk.]]
** That being said, [[spoiler: he grows out of this by late Season 2 thanks to Atra and Kudelia, and, after half of the remaining Tekkadan members wish to go on a RoaringRampageOfRevenge for Orga's assassination that will most certainly get them killed, he reminds them to follow Orga's last order: to live. He [[TheHeroDies doesn't]], however]].
* {{Determinator}}: [[spoiler: Even in the final battle, with Barbatos literally shot to pieces and Mikazuki already dead, his will keeps it moving forward! Julieta is shocked beyond words when she tears open the cockpit and discovers his body.]]
* DisabilitySuperpower: A variant. [[spoiler:The more of his body he "sacrifices" to Barbatos, the more of the suit's power he is able to utilize.]]
* DontYouDarePityMe: He doesn't consider himself to be a victim and finds Crank's [[WouldNotHurtAChild reluctance to kill him]] to be ridiculous. This takes on a more and more disturbing tone as the series progresses - by Season Two, it's clear that he's deliberately ignoring alternative ways to live his life as a coping mechanism for his terrible career.
* DoubleTap: A habit of his when he's shooting things on foot, though he hasn't shown the same tendency in his Gundam.
* TheDreaded: Both as a soldier and as a human being, Mikazuki scares friend and foe alike. Both Orga and Kudelia have admitted in separate occassions they were afraid of Mika before getting to know him better. [[spoiler: In the finale, Mikazuki's feat of defeating the Mobile Armor on the battlefield earned him the reputation of being "a demon." And in the final battle, he kills so many mobile suit soldiers that they end up having to use the Dainsleif on him and Akihiro to finally have a chance at putting him down.]]
* DropTheHammer: His preferred melee weapon is basically a giant metal club. While he's given a katana later in the first season, he has incredible difficulty using such a finese weapon until the end of the season. By season 2, he seems to have split the difference with the Lupus' sword mace, a giant, incredibly thick sword that crushes as much as it cuts. When upgrading to the Barbatos Lupus Rex, he uses a mace once again, only this time the mace's head alone is half the size of the entire mobile suit.
* DyingMomentOfAwesome: [[spoiler:Fighting a rearguard action to safeguard the escape of the rest of Tekkadan, Mika puts up such a good fight that Rustal has to resort to a Dainsleif OrbitalBombardment. Yet before the dust even settles, Mika gets right back up, [[HeroicRROD overclocks the damaged Barbatos]] again and unleashes such a smackdown despite the Barbatos falling apart around him that the Gjallarhorn troops facing him [[MassOhCrap completely freak out and almost rout]] before Iok rallies them. Mika ultimately dies from blood loss.]]
* DynamicEntry: Thanks to [[CombatPragmatist his willingness to immediately go for kill-shots]], if Mika's required to make a dramatic entrance, it ''will'' involve someone dying messily, and he makes quite a lot of dramatic entrances.
* EmergencyWeapon: A couple of them:
** He never really gets used to the sword that Teiwaz give him as part of the Barbatos's MidSeasonUpgrade, and tends to use it as a last resort if he happens to lose his mace or smoothbore cannon. After yielding to the suit-munching temptations of the Montag Corporation's wrench mace, he never looks back. [[spoiler: However, when the wrench mace is broken, Mika uses the sword to impale Ein.]]
** The 170mm {{Arm Cannon}}s on the Barbatos's fifth and sixth forms are a bit of a downgrade in firepower from the 300mm behemoth that previously served as its main ranged option, and lack its long-ranged accuracy, too. On the other hand, they're a way to knock an enemy suit off-balance while keeping the Gundam's hands free, and that's a real asset in close-quarters combat. By the time that the Barbatos has been remodelled into the Lupus for Season Two, though, the arm-guns have been upgraded in firepower enough to become primary weapons that make the Gundam a genuine threat at range.
* EmotionlessBoy: To a disturbing degree. Mikazuki rarely shows expressions, even when he's about to butcher someone.
* EveryoneHasStandards: Ruthless and [[HeroicNeutral insular]] as Mikazuki is, he's still voices his abhorrence to Gjallarhorn's massacre of hapless Dort forces.
* FatalFlaw: Mikazuki [[ExtremeDoormat lacks any sort of ambition or desire beyond doing whatever Orga tells him]]. Other characters, including Orga himself, wise up on this and begin voicing their own opinions over how wrong this is: Orga wonders what did he do to make Mika so loyal to him, Atra fears he will get himself killed fulfilling someone else's dreams and [=McGillis=] concludes that Mikazuki simply has no desire to change the world. [[spoiler:In his final moments, he admits to Julieta that fighting for Orga is [[DesperatelyLookingForAPurposeInLife the only thing gave his life meaning]].]]
* FirstKiss: [[spoiler: He kisses Kudelia in the lips after receiving a brief CooldownHug from her in episode 13.]]
* GetAHoldOfYourselfMan: He grabs Orga by the neck to break him out of his HeroicBSOD.
* GoodLuckCharm: Atra gives him a good luck bracelet matching her own. He occasionally smells it in times of stress, presumably because [[SignatureScent it reminds him of Atra]].
* HappinessInSlavery: Mikazuki only does what Orga tells him; nothing more, nothing less. When [=McGillis=] asks him what does he want, regardless of what Orga says, he responds he will only want what Orga wants. It's this comment that makes [=McGillis=] realize Mikazuki has no ambition whatsoever.[[spoiler: What this means when Orga dies however...]].
* HeIsAllGrownUp: [[spoiler: Had Mikazuki survived the events during the GrandFinale,]] character designer Yu Ito drew [[https://external-preview.redd.it/akzNLTPBpz1ejkMotNGvBOwrGUYznm9X0HfJJTK6Vfg.jpg?auto=webp&s=4608012bf87d781e5980a5b1d8a753c6a762a09d what he would've looked like as an adult.]]
* TheHeroDies: [[spoiler: At the end of the series he dies of blood loss from his mortal wounds, and while the official history may depict him as a demon, his surviving loved ones remember him as their hero. Notably, while he's not the first Gundam Protagonist to have lost their life[[note]]The first actual main character death being Amuro Ray himself, albeit he's stated at only being "missing in action" post-''Char's Counterattack'', while ''Unicorn'' indirectly proves he died pushing back Axis[[/note]], his passing is unique as it marks him as the first main character in a ''Gundam'' TV series to unquestionably die, moreso in the very same show where he debuted.]]
* HeroesPreferSwords: Downplayed significantly. The Barbatos starts out equipped with a [[CarryABigStick mace]], and doesn't get a sword until its MidSeasonUpgrade. Even after he has a sword available, though, Mika prefers the mace and only uses the sword as a smaller, lighter backup weapon. In Episode 21, when selecting a weapon, he complains that he finds the sword difficult to use and passes up on it in favor of a [[ImprobableWeaponUser massive two-handed club/wrench hybrid]] that can crush a limbs with its jaws or be used to throw around other mobile suits. However, Mikazuki ''is'' unique among Tekkadan and its allies in using a sword at all, even as a second choice, so the trope is ultimately played straight. [[spoiler: in episode 25, he finally figures out how to use it properly and wields it to deadly effect against Ein.]]
** He zigzags this in season 2. Barbatos Lupus' main weapon is a sword-mace, which is a giant, heavy sword that is used more akin to his mace from season one. Ironically, while it does have dual maces, this time they are the sub weapon, not the sword/mace. Meanwhile, much of Tekkadan has upgraded to the Shiden which carries a sword and shield kit for melee.
* HeroicRROD: [[spoiler:He pushes the limit of Barbatos' Alaya-Vijnana system to kill Ein, which costs him both his sight in his right eye and the use of his right arm when unconnected to Barbatos. He does it again during the fight with Hashmal. This time it paralyzes both of his legs. He does it one last time in the finale since he was already dying due to Gjallarhorns' OrbitalBombardment before finally dying due to blood loss.]]
* HiddenDepths: Despite seeming upon first impression like a mindless warrior who thinks of nothing but fighting, Mikazuki actually wants to run his own farm in the future if he ever retires from combat. Also, although he outwardly seems oblivious to Atra's feelings for him, the way he reacts to her good luck charm at times suggests he might reciprocate in his own way.
* IdiotHair: An odd case, since he's no more BookDumb than the others, and sometimes even the OnlySaneMan.
* IgnoredEpiphany: Mika's small regret at killing people after Kudal's accusation clearly didn't take as he's back at killing people without looking back.
* ImprovisedWeapon: Barbatos's wrench mace is a massive wrench used to perform adjustments to the Barbatos. [[WrenchWhack Mika uses it to rip Grazes in half with ease.]]
* InsaneEqualsViolent: Downplayed; Mikazuki is not insane but isn't a stable individual either. He manages to be one of the most brutal characters in the series, if not the franchise.
* InvincibleHero: On top of being an excellent pilot with ''three'' cybernetic enhancements, Mikazuki is also in possession of one of the most powerful machines in the Sol System. However, he deconstructs the trope by the [[HeroicRROD desperate measures]] he takes to win; not to mention he outsources his moral thinking to Orga. At the same time, some of his enemies are actually good people who just happen to be his enemies, which might make the audience uneasy about rooting for Mikazuki when he kills them.
** [[spoiler: In fact, it takes Rustal firing multiple railguns from outer space to finally put Mikazuki down. And even then, he puts up a good fight before finally bleeding out.]]
* ItsPersonal: [[spoiler:In the narration, he mentions that he is usually impartial to his foes and simply kills those Orga tells him to kill. When Biscuit dies, he notes that now he'll kill anyone who gets in the way and then presses Orga into taking action.]]
* JerkassHasAPoint: He can be downright ruthless, even cruel, but that doesn't change the fact that war is about survival, not acting like a boy scout. The simple fact is, every person he's killed was either trying to kill him, or personally responsible for the deaths of his brothers. These were enemies, plain and simple.
* JerkWithAHeartOfGold: Mika is often rude and can be horrifically brutal in battle, but he cares very much for his friends and does whatever it takes to protect them.
* KatanasAreJustBetter: After being refurbished by Teiwaz, the Barbatos trades out its [[CarryABigStick enormous mace]] for a large but more conventionally-sized (for a mecha) odachi as its melee weapon of choice. The 'just better' bit is slightly played with, though - it's a superbly-crafted weapon, but it's not one Mikazuki is used to, so he has a bit of difficulty at first with learning not to use it like a big metal club. Then he averts this in season 2, when he goes back to using what looks like a giant speartip that he uses mostly to bash enemies with.
* KickThemWhileTheyAreDown: Even if his opponent is already crippled, Mika never stops until the fight is finished.
* KidHero: Not only is he a Gundam protagonist (translation: teenage HumongousMecha pilot with enough skills and firepower to wipe out small armies), but he's part of the rare subset who were superhumanly-skilled warriors before ever seeing the inside of a Gundam's cockpit. It's worth noting, though, that his lethal competence isn't portrayed quite as glamorously as this trope usually implies - in fact, it's sometimes played for outright horror. He is an emotionally-scarred child soldier, after all, and children are ''not'' supposed to be able to kill that easily.
* KnightTemplarBigBrother: He nearly murders Gaelio ''with his bare hands'' when he thought they had hurt his friend's little sisters, Cookie and Cracker. Any time he sees one of his friends hurt or threaten sets off his TranquilFury.
* LadyAndKnight: ''Very much'' a Black Knight to Kudelia's Bright Lady and even Orga's Lord. Inside his mechanized armor, he kills, brutally and without mercy, anyone the latter tells him or is a threat to the former's plans.
* LetThemDieHappy: In Episode 49 [[spoiler:when a fatally injured Hush says to leave him behind and he'll catch up to him afterwards, Mikazuki still tells Hush he is counting on him in his final moments.]]
* LickedByTheDog: In Episode 41, one of Naze's babies crawls up to Mika and starts playing with him, suggesting that despite how dark Mika's character arc is getting by that time, he must still have a hidden gentle side that even a baby could recognize.
* LightningBruiser: The seventy-two Gundams of the Calamity War were distinguished by their twin reactors, giving them enormous strength and speed, and the Barbatos is jury-rigged with a Mobile Worker's Alaya-Vijnana system, giving it human-like reflexes. The combination makes Mikazuki a deadly foe indeed, and later upgrades like the Fifth/Sixth Form and Lupus add extra armour and thrusters to make the Barbatos even tougher and faster. The other Gundam Frames are shown to be just as effective, when actualized to their potential.
* {{Leitmotif}}: "[[https://www.youtube.com/watch?v=tiUxW8uyRXc Iron Blooded Orphans]]" "[[https://www.youtube.com/watch?v=g6zRd8ITN1s Hoping For You]]"
* MajorInjuryUnderreaction: He's completely nonchalant about losing the use of his right arm and eye when not hooked up to Barbatos at the end of season one. [[spoiler:And when he loses the use of the entire right side of his body when not hooked up to Barbatos at the end of season 2, Mika is relieved that he won't have to figure out what to do with himself when he no longer needs to fight. It's at this point when the rest of the cast realizes how self-destructive this attitude is.]]
* MasterSwordsman: He's pretty much the opposite of this for most of the first season, with the Barbatos's odachi being his least favorite and worst-understood weapon. He finally figures it out in the finale, though, and once Season Two rolls around and he gets a sword better suited to his preferences, the results are spectacular, despite how huge and unwieldy his weapon is.
* MeaningfulName:
** Mikazuki means "Crescent Moon". When he landed to the Earth and saw the moon, he learnt the meaning of his name for the first time.
** With Orga now aiming for ultimate sovereignty of Mars, it's quite convenient that Mika's ride is being named Barbatos Lupus ''Rex''[[note]]"King" in Latin[[/note]].
* MidSeasonUpgrade: Unlike most other Gundams in previous seasons, Barbatos gets close to 5 of them in season 1 alone, albeit these are mostly additions of armor and weapons obtained from enemy units. Season 2 sees Mika get a proper upgrade to the Barbatos Lupus, which, due to all the damage it's received over the years, is practically rebuilt entirely by Teiwaz from the frame itself to the armor. Essentially it's a brand new unit with only the irreplaceable systems (such as the Ahab reactors and components that directly relate to their ability to sync) left in place.
** After the Barbatos Lupus was severely damaged in the fight against the Hashmal, it gets overhauled into the Barbatos Lupus Rex, which is essentially another new suit besides the irreplaceable parts from the frame itself. It's outfitted with longer forearms (along with sharper claws to eviscerate enemy mobile suits, built-in 200mm machine guns and a pair of subarms to go along with them), sharper toenails (speculated to be made from the same material the Grimgerde's swords are made of), a pair of pilebunker heels and a mace made large enough to destroy ''warships'' with a pilebunker on each tip.
* MoreDakka: The Lupus's revised ArmCannon set are 200mm monsters with a blistering rate of fire, particularly by the standards of a show where most suit-sized guns are relatively slow-firing semi-automatics, and can effectively paralyse enemy suits with the constant stream of massive impacts they dish out.
** Those can also be swapped out for a pair of Rocket Launchers, which are great for [[spoiler:thinning out the Pluma horde that the Hashmal is summoning.]]
* NeckLift: Delivers a rather terrifying one to Gaelio when he thinks the latter's car has run over the Griffon siblings.
* NervesOfSteel: To an extent that's both impressive and disturbing. In battle, he's basically a murder-robot that sometimes pilots an even bigger murder-robot - he's calm, analytical, spectacularly brutal, and excellent at compartmentalising potential distractions. Throughout the series, he never shows fear and only very occasionally shows visible anger, even in the most dangerous and stressful circumstances. It's very telling that his shockingly out-of-character NotSoStoic moment in his battle with the Hashmal consists of ''slightly raising his voice to insult it''.
* NeverLearnedToRead: When a mechanic hands him the Barbatos' manual to look over, he just gives the guy a sad smile and hands it back. Being a ChildSoldier in an entire unit of nothing but ChildSoldiers, he's not alone in being illiterate. Eventually, Kudelia begins to teach him (and the other kids in Tekkadan) how to read.
* TheNicknamer: A dark example. He doesn't believe in learning the names of people he's about to kill, but recurring enemies will get half-hearted nicknames, like "Chocolate Man" for [=McGillis=] (a reference to his handing out some chocolate as an apology for nearly hitting Cookie and Cracker while [[VillainsOutShopping driving around on Mars]]) and "Gali-Gali" for Gaelio (a [[MaliciousMisnaming possibly deliberate]] corruption of his first name).
* NoHoldsBarredBeatdown: Frequently delivers these. He's a CombatPragmatist with anger issues, and is perfectly willing to hit enemies as hard as he can and as often as he can until they're very thoroughly, visibly dead.
* NoNonsenseNemesis: A rare heroic version. If he wants you dead, then you're ''dead'', in a ''very'' bloody fashion, and there will be no [[BreakingSpeech speeches]] or [[LetsFightLikeGentlemen challenges]] that are going to make him slow down. Best example of this is when Carta Issue intercepts Tekkadan in Alaska. She challenges them to a duel and tells them they have an hour to organize themselves to do it. Mika's response? Say "you're boring" and [[CurbStompBattle slaughter Issue and her companions in the space of a minute]].
* OOCIsSeriousBusiness:
** Given his utter devotion to Orga, his refusing Orga's order to [[spoiler:not engage the Mobile Armor]] shocks Orga and show just how serious a threat it is.
** In the subsequent fight, he shows a hint of visible anger beyond his usual TranquilFury, showing that his usually unbreakable control is gone and he's now capable of ''anything''.
* OlderThanTheyLook: Most viewers don't guess that he's actually fifteen on a first viewing (he's rather short, and the large, baggy coat that he wears continuously when not piloting makes him look smaller, as if he's still growing into his clothes). Probably justified in that malnutrition stunted his growth.
* OnlyICanMakeItGo: He set the Barbatos's [[BrainComputerInterface Ālaya-Vijñāna system]] to such a high output the only other person who tried to use it immediately blacked out from the strain. No one else has tried to use it since.
* PinballProtagonist: Played with. Mika's most major contribution to the story is to do whatever Orga tells him... and to do it with such enthusiastic ferocity that his fear of disappointing his best friend becomes Orga's FatalFlaw. [[spoiler:His most active intervention, the GetAHoldOfYourselfMan speech after Orga goes into a HeroicBSOD, only worsens the problem.]]
** [=McGillis=] even notes with disappointment that he thought he and Mikazuki were kindred spirits, but realized that Mikazuki has no real ambition of his own. He simply uses his great power and skills for someone else's dreams and otherwise just meanders through his own life.
* PintsizedPowerhouse: He's a shrimp, but he lifted a grown man up by his throat and nearly strangled him to death with one hand.
* {{Polyamory}}: Mika is at the center of a LoveTriangle between him, Kudelia and Atra. Unusually enough for a love triangle setup, the girls play RichSuitorPoorSuitor in terms of upbringing (Kudelia is from a fairly wealthy family, Atra is a street rat much like Mika) but the monetary status does not really play into the overall romance. The triangle eventually grows to the point Atra proposes to Mika and Kudelia to enter a polyamourous relationship after seeing Naze's harem (which both of them accept). Mika's eventual plan is to marry them both and retire to a farm after the fight with Gjallarhorn ends [[spoiler: and the girls eventually do move to one such farm in the epilogue after Mika kicks the bucket, as a way to honor his legacy.]]
* PowerAtAPrice: [[spoiler:Gives his arm and eye to Barbatos in order to gain enough strength to kill Eins. Now he can only use them when attached to it.]]
* PowerLimiter: As with all Gundam Frames, the Barbatos is equipped with a limiter that prevents the information feedback from killing its pilot. [[spoiler:Mikazuki has shut it down twice; first in his fight against Ein in the season 1 finale, again while confronting Hashmal, and one last time in Tekkadan's last stand against the Arianhrod fleet.]]
* ProtagonistPowerUpPrivileges: The Barbatos starts as the most advanced weapon in Tekkadan's arsenal and gets the lions share of upgrades. In season 2 where everyone else gets a MidSeasonUpgrade, Barbatos gets two.
* PsychoForHire: Sort of. He has all of the mannerisms and motives necessary for this trope, but he only works for one person and he's absolutely loyal.
* RasputinianDeath: [[spoiler:During the final battle, he not only took a direct hit from a Dainsleif, but also took at least three axes to the chest, his own tail to rather brutally remove said axes, several shots from Reginlaze Julia, explosion from Barbatos breaking apart, before eventually succumbing to the backlash of having removed the mobile suit's limiters]].
* RedBaron: In Season 2, he has become known as the Devil of Tekkadan for his ferocity fighting on the front lines.
* RedEyesTakeWarning: [[spoiler:After Mikazuki overclocks the Barbatos Lupus to fight Hashmal, its optics change from green to red. Mikazuki's own eyes also become red due to the massive bloodshot.]]
* RedOniBlueOni: Among Tekkadan's MS pilots, he's the stoic Blue to both Akihiro's and Shino's emotional Red.
* ReflectionlessUselessEyes: By the end of season 1, [[spoiler:his right eye is blind when not hooked up to Barbatos as shown by it's lack of catchlights, which return when hooked up]].
* ReiAyanamiExpy: The first in the ''Gundam'' franchise, and a GenderFlip at that. He's emotionless, short in stature, has short hair, is a ChildSoldier, has significant injuries, NoSocialSkills, UndyingLoyalty to Orga, and to top it off, a mecha pilot. As an added bonus, his name means "Crescent Moon", which has connotations with the cold (like Yuki and Rei), and was an Imperial Japanese warship. Unlike other examples, though, he rarely becomes more humanly expressive, and this lack of development is played for drama.
** As regarding his character design, he comes off as another GenderFlip of [[Characters/KanColleOne a Mutsuki-class destroyer]] (also his namesake), minus the eye color.
* RevengeBeforeReason: He used to fight for survival, [[spoiler: starting from Biscuit's death, whoever blocks his way is his enemy and he will shred them into pieces.]]
--> [[spoiler: "I don't care who you are, it doesn't change that '''you are my enemy'''."]]
* RoaringRampageOfRevenge: [[spoiler: When he [[OneManArmy swept down Carta and her squadrons on his own]] to avenge Biscuit's death. It also enters ExtremeMeleeRevenge territory as he only uses melee attacks and deliberately prolonged the beating instead of killing them quickly.]]
* ShedArmorGainSpeed: [[spoiler: In order to chase up Graze Ein's agile maneuverability, Mika detaches the armor of Barbatos and resorts to his katana.]]
* ShipTease: With Kudelia, [[spoiler:whom he kisses in episode 13]], and Atra, who made the good luck bracelet on his left arm (and outright asks him to make babies with her). [[spoiler:He ultimately accepts both of them, and succeeds in [[SomeoneToRememberHimBy having a baby with Atra]] before his death, Kudelia and Atra in turn getting married afterwards while raising their son, Akatsuki, together.]]
* ShouldersOfDoom: The upgrades that the Barbatos gets over the course of the series are visually signified by changes in its shoulder armour. The 'doom' part comes, of course, from the fact that bigger and more impressive shoulders mean Mika has more and better ways to kill you.
* ShutUpHannibal: Trying to distract Mikazuki with a BreakingSpeech in the middle of a fight just isn't a smart thing to do. As multiple enemy pilots have found out, he'll just file it away for later consideration and then get right back to killing you. Given some of his enemies are sympathetic characters, this can also qualify as ShutUpKirk.
* TheStoic: Doesn't show his emotions outwardly, but he does have strong opinions and makes them known through actions. This makes the payoff where he actually starts raising his voice a little during [[spoiler:the Hashmal battle that seals his fate]] all the more terrifying.
* TheSnackIsMoreInteresting: He's been guilty of this several times, thanks to those Mars palms. There's also those sandwiches made by Atra and Kudelia, which he's still chowing down on while [[ExcuseMeWhileIMultitask revising his English and maneuvering the Barbatos through some tricky wreckage.]]
* SugarAndIcePersonality: Cold and distant to most people, and not one for conversation most of the time. Atra and Kudelia are both capable of bringing out his warmer side.
* SunkCostFallacy: [[spoiler:It turns out that he justifies his brutality through his faith in Orga's plan for Tekkadan's future, and he takes Orga's breakdown over the death of Biscuit extremely poorly because it might threaten that plan and retroactively make his own deeds worthless. Naturally, this ends up giving his friend an even bigger SunkCostFallacy problem, eventually leading to Tekkadan's doom.]]
* SupportingProtagonist: Orga, Kudelia and [=McGillis=] are the ones really moving the story forward with their political agendas. Mika is just there for the ride.
* TearsFromAStone: When Mika is about to execute Carta with her own bent blade, the Barbatos can be seen shedding tears. Whether it is BerserkerTears from Mika or it being sad is another question.
* TheseHandsHaveKilled: A subtle example. Kudelia is the first person to notice that his hands shake after killing someone, in one of several early indicators that he's not quite as much of a cold, remorseless killing machine as he appears... and that trying to be one is taking a serious toll on him.
* TogetherInDeath: A platonic example. [[spoiler: After Orga dies Mika's DeathSeeker tendencies get ramped up and after he starts to die, he declares the the day the he met Orga was the day he was "born." The last we see of him, he's reunited with Orga once again.]]
* ToxicFriendInfluence: Has a bit of a ''mutual'' one going with Orga. Because Orga promised him when they were young to take him to a new world, Mikazuki holds him to that promise. Mikazuki for his part, despite being perfectly willing to be used as a tool to fulfill Orga's dreams is also constantly pushing Orga more and more into callous thinking [[spoiler: being the one to snap and force him out of grieving Biscuit's death and later disobeying Orga's orders against fighting the Mobile Armor.]] That being said, [[spoiler: in the wake of Shino's SenselessSacrifice and Orga's resulting frustration and grief from it]], he shows awareness of his role in often pushing Orga to go far, even too far, and doesn't sound proud of it.
* TrademarkFavoriteFood: He's frequently seen snacking on "Mars palms" (that is, Martian-grown dates).
* TranquilFury: If Mikazuki gets angry, this is the form it will take. No screaming, no yelling, no expressions of rage on his face; he speaks calmly and levelly, with only a slight edge to his voice and a cold fury in his eyes betraying his state.
* TroublingUnchildlikeBehavior: Par the course of someone being a {{Child Soldier}}, but it ''really'' gets ramped up late in the series.
-->'''Mikazuki:''' "Hey Orga, what should I do next? Is this our place? I won't stop until we get there. I can't stop.... Hey, how many should I kill? How many more until we get there? Tell me, [[FullNameUltimatum Orga Itsuka.]] You'll take me there, right? What should I do next? [[TheUnfettered Who should I kill next? What should I destroy next? If I can reach your goal, I'll do anything.]]"
* UndyingLoyalty: To Orga. He goes along with whatever he decides. "What are we gonna do, Orga?" No matter what Orga says in reponse, he will do it. [[spoiler:It gets to the point by the second season, he's lost the use of his entire right side of his body and he's actually happy because that means he can just keep fighting for Orga. When when Orga dies, Mika decides to follow Orga's final order, that being "Survive and live happily at all costs."]]
* UnscrupulousHero: A ChildSoldier who has no qualm on killing, he does not have the concept of mercy when it comes to [[KilledMidSentence disposing enemies when they're still speaking]], often [[TheNicknamer gives vulgar nicknames to enemies]] who managed to survive his encounters. And he remains [[TheStoic in an unnervingly calm mood]] all the time. Even his own friends admit he has to be handled with kid gloves at times.
* UnwittingInstigatorOfDoom:
** Being a soldier who kills to survive and [[spoiler:avenge his friends]], Mika often takes ruthless solutions to deal with his enemies, however, his actions inadvertently contributed to Ein and Gaelio's StartOfDarkness and the CycleOfRevenge between them, namely [[spoiler:him [[MercyKill mercy killing]] Crank as well as dishing out an ExtremeMeleeRevenge towards Carta.]]
** In season 2, [[spoiler:his destroying the Mobile Armor is what inspires [=McGillis=] to go ahead with his coup, which ends disastrously for all involved.]]
* WideEyesAndShrunkenIrises: Seeing this expression on Mika's face is the surest sign that something's ''really'' pissed him off. [[RunningGag Amusingly, it doesn't take much to snap him out of it.]]
* WolverineClaws: The Barbatos Lupus Rex is upgraded with claws made of rare ultra-hard metal and enlarged, strengthened arms, giving them the power and precision to be effective weapons.
* WouldHitAGirl: While the entire Tekkadan already has no problem hitting women, Mika worths a special mention. In the battle against the Turbines, when the rest were trying to defeat the Turbines without bloodshed, Mika fully intended to ''kill'' Lafter when battling against her, it was fortunately halted by [[DefeatMeansFriendship Naze admitting his defeat and befriending the group]]. [[spoiler: In the battle against Carta Issue, the Gjallarhorn officer who killed [[ItsPersonal Biscuit]], Mika immediately went for the kill and wasted her and her entire group.]] In Season 2, he has no problem fighting against Julieta as well.
* WreckedWeapon: He gets the Barbatos's maces lost and/or destroyed so often that it becomes a dark, subtle RunningGag. It's particularly noticeable since most of his other weapons tend to fare considerably better. [[spoiler:the wrench mace got it worse, getting pulverized by the Graze Ein's PileBunker.]]
** [[spoiler:The Barbatos itself is presumably this by the end of the series.]]
* YouShallNotPass: [[spoiler: In the finale, he stays behind with Akihiro to hold off the Gjallarhorn army while the rest of Tekkadan retreat. He doesn't survive.]]

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/gundam_ibo_tekkadan_orga_itsuka.png]]
-> '''Main mecha''': TK-53 CGS Mobile Worker, TK-53/s CGS Mobile Worker Space Type

The leader of CGS's Third Group and Mikazuki's closest friend. He recognizes that the rest of CGS cares absolutely nothing for them, so takes the job of ensuring their safety on himself -- even at the cost of CGS's displeasure. He's well aware of Mikazuki's fanatical devotion to him and takes pains not to abuse their relationship. After the Gjallarhorn attack on CGS and the Third Group being sacrificed to delay them, it's Orga who sends Mika to pilot the Barbatos in their defense, and it's Orga who floats the idea of taking over CGS afterward. While instrumental in the creation and survival of Tekkadan, Orga is still young and occasionally makes bad decisions -- particularly by putting Mika's (rarely expressed) desires before what might be best for the group as a whole.

!!Chryse Guard Security Adults

[[folder:Todo Mirconen]]
!!!Voiced by: Creator/YutakaAoyama (Japanese), Creator/KirkThornton (English)
One of the First Group defectors remaining in Tekkadan, and allowed to sit in on Orga's meetings due to rank alone. Back then his only real role was to yell at the kids and keep them in line, and he's not one to throw out the old ways...
----
* DangerousDeserter: Of a sort. [[spoiler: After being kicked out of the airlock by Orga, he is instructed by Gjallarhorn to stop or slow down Tekkadan, which he does by bribing the Brewers to attack them. And he's currently kept by Montag as his informant and right-hand man.]]
* DirtyCoward: He's a lot less loudmouthed after the CGS takeover, and with good reason.
* HateSink: No one likes him, mostly due to being totally unsympathetic and having [[GodwinsLaw a mustache like Hitler]].
* IFightForTheStrongestSide: After Orga expels the First Group, Todo decides to stick around since he saw Orga's squad as his meal ticket. After Mikazuki kills Crank, fearing retaliation from Gjallarhorn, [[spoiler: Todo becomes a Mole and later jumps ship after Orga kicks him out.]]
* KarmaHoudini: [[spoiler: Shown to get well-off thanks to working as [=McGillis'=] informant at the end of Episode 25.]]
** In Episode 49, [[spoiler: he still manages to escape with his life after [=McGillis=] dissolves both the Montag Company and the Revolutionary Fleet.]]
* RewardedAsATraitorDeserves: [[spoiler: He sells Tekkadan out to Gjallarhorn, only to learn that Gjallarhorn and the Orcus Company don't have any qualms with killing him along with the rest of Tekkadan. Subverted as [[DoWithHimAsYouWill he's delivered to Gjallarhorn alive and well, kinda]].]]
* ShamefulStrip: [[spoiler: After Orga figures out that he betrayed him, he strips Todo down to his boxers and sends him in a pod to [=McGillis=].]]
[[/folder]]

[[folder:Maruba Arkay]]
!!!Voiced by: Creator/KatsuhisaHouki (Japanese), John Snyder (English)
The ''actual'' head of CGS, which is technically a non-combat role. So fleeing the moment Gjallahorn came knocking? [[BlatantLies Totally reasonable.]]
----
* BadBoss: Discounting everything else, he's responsible for enforcing the Alaya-Vijnana system on all the kids, acquired in bulk on the cheap since they're all "human debris", literally dumping the 40% that were crippled in the process after berating the failures as useless. At least 1 committed suicide over this. And Orga's most likely the only one he can ''name.''
* CommutingOnABus: Disappeared for about 6 eps, resurfacing only after he'd found new backing... with [[TheFamilyForTheWholeFamily Teiwaz.]] After another 2 eps, he's out of the picture again.
* DirtyCoward: Known mainly for being the first to flee when Gjallahorn showed up.
* HiddenDepths: In the preview for episode 7, Nadi says that Maruba was a lot nicer in his youth. Maruba apparantly owned a pair of puppies that he used to dote on.
* LesserOfTwoEvils: Orga acknowledges that while Maruba was a scumbag, it would be worse to leave the 1st Corps group in charge as they viewed the boys as even more expendable than Maruba did. That and their lack of brains would eventually leave them all dead. This led Orga to decide it'd be best to just cut out the middle man and run the joint himself. This is thrown out of the window in Episode 7 where Orga is ready to execute him and is only stopped by Naze, not because of morality but because he didn't want Maruba's blood to spill on his bridge.
* MadeASlave: Naze forces him to become a slave miner to repay Teiwaz for the money Maruba's fruitless and unjustified quest for vengeance cost. [[AssholeVictim He totally deserved it]].
* NeverMyFault: Cleared out the safe at CGS before he fled, and still expects Orga to hand over all the remaining assets. This would have included the Barbatos, which he never really knew the true value of.
* NiceJobFixingItVillain: Right when Tekkadan needed Teiwaz, he brought their subsidiary the Turbines to them in an attempt to take back his property. The Turbines leader was so appalled once learning of Maruba's treatment of them that he was willing to hear Tekkadan out and get them the support they needed.
* SatelliteCharacter: Not even to another character, but to the developments of CGS.
* TookALevelInJerkass: InUniverse, Nadi mentions that he knew Maruba when he was younger and he wasn't nearly as much of an asshole as he was in the present.
[[/folder]]

[[folder:Haeda Gunnel]]
!!!Voiced by: Creator/TaroYamaguchi (Japanese), Creator/RichardEpcar (English)
The leader of CGS's first division and main commander of their forces.
----
* AssholeVictim: Haeda's death is in part to demonstrate how cold and violent Mikazuki is as he dispassionately executes Haeda as he's tied up. Up till that point Haeda was depicted as a violent abusive bully who abandoned the third division to die and then blamed and attacked Orga when he objected. Killing him shows Mika's darker side but still keeps him sympathetic.
* BadBoss: Much like Maruba though Haeda's much more physical about it. He's quick to strike the kids under his command and throw his weight around. The first opening features him punching them in the face as they stand at attention.
* HateSink: Haeda's limited role in the show is to give someone for the audience to hate and root against. He's abrasive, violent, demeaning, and frequently beats children. Maruba's unpleasantness is largely balanced by comedy at his expense and Haeda's abandoning the kids to Gjallahorn makes him more of a target for hate than the largely faceless Gjallahorn soldiers.

!!Chryse Guard Security (CGS) / Tekkadan

A group of PrivateMilitaryContractors hired by Earth to help police the Martian settlements, our heroes are members of CGS's Third Group. A [[RagTagBunchOfMisfits rag-tag bunch]] of ChildSoldiers, they decide to [[TurnedAgainstTheirMasters go rogue]] after the adults of CGS deploy them as CannonFodder to delay a Gjallarhorn attack while the rest of CGS runs away. The Third Group subsequently rename themselves Tekkadan, the iron flower.

* LadyAndKnight: In the eyes of the Dort colony unions, Kuedelia and Tekkedan are precisely this; "The Maiden of Revolution and the brave knights who guard her". Eugene remarks how they're treated as heroes because of it.

* PrivateMilitaryContractors: As members of CGS.

* TheScapegoat: Rustal Elion pins all his war crimes on Tekkadan and permanently ruins their reputation. [[spoiler: The epilogue states that with the formation of the new democratic Gjallarhorn and the free, independent Mars, everyone now remembers Tekkadan as war criminals. Only a few know the truth but they can never reveal it; otherwise, they'd jeopardize the Gjallarhorn-Martian Union alliance and put the surviving members in danger.]]

%%%%%% How so?
%%%%* KickThemWhileTheyAreDown: Has a tendency to do this.

* SunkCostFallacy: [[spoiler:It turns out that he justifies his brutality through his faith in Orga's plan for Tekkadan's future, and he takes Orga's breakdown over the death of Biscuit extremely poorly because it might threaten that plan and retroactively make his own deeds worthless. Naturally, this ends up giving his friend an even bigger SunkCostFallacy problem, eventually leading to Tekkadan's doom.]]

* CelibateHero: In episode 9, he says he's not interested in women when prodded by Shino and Eugene. Whether he literally means hes not sexually attracted to them or that he finds women a distraction it's not delved on.

* CryIntoChest: She cries in Mikazuki's arms [[spoiler: after Fumitan and Naze's deaths.]]

* ThenLetMeBeEvil: Downplayed example. [[spoiler: In episode 42, he reflects on Galan Moss' words that good people die first in battle, stating that if it means more people important to him will die, then he's through with being a good person.]]

** As regarding his character design, he comes off as another GenderFlip of [[Characters/KanColleOne a Mutsuki-class destroyer]] (also [[NamesTheSame his namesake]]), minus the eye color.

* NamesTheSame: Shares his surname with Sayla Mass, one of the main characters of the original ''Anime/MobileSuitGundam''.

* HeroicRROD: [[spoiler:He pushes the limit of Barbatos' Alaya-Vijnana system to kill Ein, which costs him both his sight in his right eye and the use of his right arm when unconnected to Barbatos. He does it again during the fight with Hashmal. This time it paralyzes the entire right half of his body.]]

* AnAxeToGrind: Since he starts out piloting a looted Graze, his primary melee weapon is, of course, the standard ax. When he upgrades to the Gusion Rebake, though, he sticks with the weapon type - this time, in the form of a massive, razor-sharp halberd with a telescoping handle.

* AnAxeToGrind: His Ryusei-Go is still the same old Graze under all its mods and emergency repairs, and it still uses the same old Graze ax in suit combat.

* DarkSkinnedBlonde: It's not obvious until he's alongside the other guys, though.

* AmbiguousDisorder: Obviously an effect of his experiences as a ChildSoldier, he's both incredibly indifferent to most of what goes on around him and [[SociopathicHero prone to sudden violent outbursts]] if you ''do'' manage to get to him. He also seems to outsource all of his moral thinking to Orga, making him look positively psychopathic at times. He'll gun down helpless prisoners and wounded enemy combatants without breaking his usual blandly calm demeanor, as long as it's under Orga's orders. His behavioral tendencies seem to be consistent with Schizoid Personality Disorder (i.e. emotional coldness, indifference, lack of motivation, LackOfEmpathy).

* AmbiguousDisorder: When we first see her, she's getting distracted at a really bad time, ''while driving''. And then there's that time with the ImagineSpot. We know now she was malnourished as a child, so it might be that.
