!Madlax [[spoiler:(The Gatekeeper of Hell is All Alone)]]

-->''Voiced by: Creator/SanaeKobayashi (Japanese) Creator/NancyNovotny''

An agent for hire in the war torn country of Gazth-Sonika. [[spoiler:She is a part of Margaret, released after the horrible plane crash incident.]]
* ActionGirl: As the highest rated mercenary in Gazth-Sonika, this is a given.
* AllLovingHero: She's kind to everyone, sticks her neck out for people she barely knows, and only fights to bring an end to the war in Gazth-Sonika. A perfect example of this is when she's hired to publicly assassinate the commander of Gazth-Sonika's armies, Guen [=McNichol=]. When she's told that the target was also the person who commissioned the hit, she sneaks into his residence at night and, after discerning his motives, comforts him before leaving.
* AntiHero: She's not a bad person once you get to know her, she'll stick her neck out for friends and even acquaintances, and she's only fighting to put an end to the war as quickly as possible, but she's still a mercenary-- considered to be the very best (read: possessing the highest bodycount) in Gazth-Sonika-- who kills hundreds without really batting an eye.
* AssKickingPose: She has a lot of these.
* {{Badass}}: The biggest one of them all.
* BadassAdorable: Madlax is oh so very sweet and cute for a mass-murderer.
* BiTheWay: She's shown some interest in men, but her relationship with Vanessa is decidedly ''not'' platonic.
* BigDamnHeroes
* CodeName: Her name has always simply been known as MADLAX.
* CompressedHair: Her hair disappears whenever she wears a motorbike helmet.
* CursedWithAwesome: [[spoiler: Her {{Immortality}}.]]
* DissonantSerenity: She's terrifyingly calm whenever she fights. Sometimes, she even closes her eyes.
* ExtraordinarilyEmpoweredGirl: She has ''extremely'' honed combat instincts and, despite her young age, several years of hard combat experience under her belt, but aside from that she's pretty much normal. [[spoiler:We find out later in the series that she's also immortal, but she still qualifies for this trope because her immortality really isn't any help in combat because it doesn't heal her fast enough, and while Madlax can't die, she can still ''lose''.]] We've even [[Pantheon/{{Heroes}} deified her]].
* FingerlessGloves
* GunFu[=/=]GunKata: She uses both.
* TheGunslinger: Well, naturally.
* IJustWantToBeNormal
* InnocentFanserviceGirl
* ImpossiblyCoolClothes: The red and [[WomanInWhite white]] cocktail dresses.

* MeaningfulName
* MsFanservice
* MysteriousPast: Just one of many.
* OneManArmy: Platoons- even companies- of soldiers can do nothing but die in droves when Madlax starts fighting.
* OnlyKnownByTheirNickname: "Madlax" is her codename, but everyone uses it.
* OnlyOneName
* OutOfTheInferno: In Episode 1.
* ThemeMusicPowerUp: Yanmaani!
* TrademarkFavoriteFood: "Yeah, PASTA!"
* WeaponOfChoice: The SIG P210.
* WhoWearsShortShorts

A usually sleepy eyed and slightly amnesiac aristocrat.


* AwfulTruth
* BadassAdorable: [[spoiler:Becomes this in later episodes.]]

* [[spoiler:HiddenEyes: Dark Margaret.]]

* MamaBear: A surrogate one for Margaret.
* {{Meganekko}}: Episode 14.
* {{Meido}}
* MessianicArchetype: [[spoiler: Tragically becomes one.]]
* NinjaMaid: Oh God, does she ever prove it. In fact, she did such a good job of proving it that we've made her the ''[[Pantheon/{{Combat}} Greater Goddess]]'' of {{Ninja Maid}}s.
* OldRetainer: Her grandpa was this, and she'd fit if not for her age since the Bakers have served the Burtons for generations.
* PluckyGirl: Pretty much one the entire series.
* SmallGirlBigGun: One episode she gets on a mounted gun and starts firing off like hell.
* UndyingLoyalty
* ZettaiRyouiki: Episode 14. The only other episode that she wears something ''other'' than her maid uniform.

* TeachMeHowToFight: When shit's about to go down, she asks Madlax to teach her how to use a gun.
