''Soldiers of the Gran Knights, Combine!''

''Chōjūshin (Super-Heavy God) Gravion'' is a 13-episode SuperRobot series directed by Creator/MasamiObari and released in 2002 by {{Creator/GONZO}}. Think ''Anime/GaoGaiGar'' loaded with [[{{Meido}} maids]] instead of HotBlooded [[{{Transformers}} Autobot]] [[{{Expy}} Expies]].

[[WarWasBeginning The Earth's about to come under attack]] by an alien race called the Zeravire. However, a mysterious billionaire named Klein Sandman has prepared for the invasion with God Gravion, a [[SuperRobotGenre Super Robot]] that uses the power of gravity to fight. The protagonist is Eiji Shigure, a young man who infiltrates Sandman's St. Germain Castle in search of his missing older sister Ayaka, and is recruited as part of the Gran Knights. The story is given a different slant: although Eiji is the main character, he's effectively TheLancer of this particular Six Man Band, piloting the G-Attacker, the God Gravion's right leg, rather than being the main pilot.

The series seems to come to an abrupt end, but is concluded in the 12-episode sequel ''Gravion Zwei'', which answers many of the series' major mysteries and finally promotes Eiji to the actual lancer seat of the Sol Gravion.

Some of the characters make cameos in ''Anime/DancougarNova'', the remake/sequel to ''Anime/{{Dancougar}}'', and some viewers consider it to be the unoffical "[[SpiritualSuccessor third season]]" of the show.

Most definitely ''not'' to be confused with ''{{Manga/Gravitation}}''.

!!This series provides examples of:

* AbsoluteCleavage: Mizuki. All but one of her outfits reveal a [[BoobsOfSteel copious amounts of cleavage]], and [[http://img13.imageshack.us/img13/3881/65603685.jpg the fact that she has a lot to show]] helps.
* AchillesInHisTent: Okay, being pissed at Touga for [[spoiler: attempting to kill Cecile along with that Zeravire]] is understandable. But [[spoiler:leaving the team to fight a ''more powerful'' Zeravire by themselves]]? [[WhatTheHellHero What The Hell, Eiji]]?
* AmbiguouslyGay: Jose, the AmbiguouslyBrown DarkSkinnedBlond who loves soccer, is [[CampGay somewhat flamboyant in his mannerisms]].
* AscendedFanboy:
** Sandman might as well be an older [[VideoGame/SuperRobotWars Ryuusei Date]].
** Alex Smith, recurring MauveShirt: He eats ''natto'' while dressed like [[VideoGame/FatalFury Terry Bogard]] and fanboys Gravion. Then he turns out to be a Gran Trooper (who is absolutely ''[[CrowningMomentOfFunny thrilled]]'' to shake Gravion's hand).
* AttractiveBentGender: Eiji and Touga looks pretty good in a dress; Alex unknowingly hits on them - Eiji twice.
* BadassCrew: The Gran Knights, as well as the Gran Troopers of ''Zwei''.
* BattleBoomerang: God Gravion's Graviton Crescent, which serves as its primary finisher during the first season.
* BecomingTheMask:
** [[spoiler:What happens when you put on Raven's mask.]]
** [[spoiler: Mizuki, sent to spy on the Gran Knights, truly starts feeling like she belongs there.]])
* BishieSparkle: Sandman gets these a few times. Cue mass {{Squee}} from his MaidCorps.
* BlindIdiotTranslation: The very first episode features the infamous "Status Clitical" emergency screen.
%% * BridgeBunnies: The above-mentioned MaidCorps.
* BrotherSisterIncest: [[spoiler:Hugi towards Lufira, his younger sister.]] The fact that it's a robot does not change the fact that [[spoiler: he still made out with a fawning [[ReplacementGoldfish robot he created and programmed]] who ''looks exactly like his younger sister''.]]
* BigBrotherInstinct: {{Inverted|Trope}} Eiji's search for older sister Ayaka is what brings him to the castle.
* BoobsOfSteel: The bustiest maid in the series is Cookie, who is shown to have super strength and is head of the security division. The bustiest female member of the grand knights, by a wide margin is Mizuki, who is the only female grand knight shown to be proficient in any hand to hand combat.
* CallingYourAttacks: This ''is'' a SuperRobot show.
** Also parodied in the Hot Spring episode: Sandman calls out the names of his ping-pong serves/smashes. [[MundaneMadeAwesome And it is awesome]].
* ChasteHero: Touga, justified because his training didn't include socialization; the closest he gets to romantic intent is obliviously asking ''Eiji'' to "marry him."
* ChestBlaster: God Gravion's Graviton Arc and Sol Gravion's Sol Graviton Nova.
%% * CombiningMecha: Naturally, the Gravions.
%% * TheComicallySerious: Raven.
* CoolSword: God Gravion has the Graviton Sword in its chestplate, subverted in that while it's used as a finisher the first time, every other Zeravire is basically immune to it and thus it only gets used a small handful of times. The White Steel Fang definitely qualifies, though.
%% * CuteClumsyGirl: Eina.
%% * DeathSeeker: [[spoiler:Hugi and Sandman]].
% * DrillTank: G-Driller.
* EleventhHourSuperpower: The Chōjūken in ''Gravion'' and [[spoiler:Ultimate Gravion]] in ''Zwei''.
* {{Expy}}:
** Compatible Kaiser and G Compatible Kaiser of the ''[[VideoGame/SuperRobotWarsOriginalGeneration Original Generation]]'' sub-series bears striking similarities and attacks to the God Gravion and Sol Gravion respectively. It helps that Masami Obari, ''Gravion's'' director and character/mecha designer, was tasked by Banpresto to redesign the Kaiser.
** Sandman is like taking [[VideoGame/SuperRobotWars Masaki Andoh, Shu Shirakawa, and Ryusei]] and smashing the result into a single character
* {{Fanservice}}: A signature of any work by Obari.
** Just to give you an idea: The cover for the DVD release features the main female cast at the beach, with Faye and Luna ''taking each other's bikini tops off''. God Gravion is faintly in the background, as if to assure you that this show is about giant robot fights.
* FormFittingWardrobe: [[spoiler:Ayaka as Raven, whose breasts are hidden by the top she wears as Raven]].
* {{Gainaxing}}: In abundance. Currently the page image.
* GetAHoldOfYourselfMan: Raven snaps Sandman out of his [=BSOD=]; Eiji does likewise for Touga.
* GratuitousEnglish: Notably Faye Xin Lu's CatchPhrase: "Jack Off", which the dub mercifully avoided.
%% * HardDrinkingPartyGirl: Mizuki Tachibana.
%% * HeroicBSOD: Touga, Leele... and Sandman.
* HeroicSacrifice: [[spoiler: Eina; [[BackFromTheDead she gets better]]]].
* HoistByHisOwnPetard: [[spoiler:Hugi manages to get multiple hoistings in the same scene: The failsafe device that shuts down the Genocidron System, upon seeing Leele, causes the core of Goma to stop functioning and get destroyed. His RidiculouslyHumanRobot clone of his dead sister stops him from killing Sandman due to InstantAIJustAddWater, and since he was also plugged into Goma's core it weakens him enough for Sandman to cut him down. Add in the fact he revealed himself the BigBad just to lure Sandman out to fight...]]
* HumanAliens: [[spoiler:Sandman, Leele and Hugi, as well as the population of Selias and Llambias]].
* IdiotBall: Gravion episode 10. Hey, Eiji, you don't want to the captured Cecile to be killed when Gravion is forced to make it's attack? How about running in and ''getting her out of there'' instead of standing around and yelling for Touga not to attack? Okay, good, you've reached and freed her. Now it's time to run away as fast as--''why the hell are you pointing a gun at Gravion?!'' Move! Get off the giant monster!
* IdiotHero: Touga takes this to the point of GeniusDitz.
* LatexSpaceSuit: All pilot's suits, which has {{fanservice}} for [[FemaleGaze both]] [[MaleGaze sexes]].
* LukeIAmYourFather: [[spoiler:Sandman is Leele's.]]
* MaleGaze: Other than [[MauveShirt pilot Alex]], it's completely inverted; it's generally the girls who stare in awe at Klein Sandmann.
* MarshmallowHell: When crowding in a narrow vehicle, Mizuki puts Eiji's head between her boobs.
%% * MauveShirt: [[TheFederation EFA]] pilot Alex; the Gran Troopers.
* MaidCorps: Klein Sandman has a decent amount, ''[[https://abload.de/img/yande.re30952anyaarmog2s1l.jpg as you can see here.]]'' What stands out is that they all look different and have outfits specific to their tasks (more typical servants, but also engineers, guards, nurses), and run the whole gamut from TokenMiniMoe adorable to mature and sexy.
* {{Meido}}: A big number of the cast are hired as maids by Klein Sandman. They run the whole ganmut
%% * MidSeasonUpgrade: Sol Gravion.
* MissedTheCall: [[spoiler:Faye missed the call, though not for lack of [[JumpedAtTheCall jumping]]; but Sandman chose Touga as Gran Kaiser pilot at the last minute]].
* TheMole: [[spoiler:Mizuki's actually a spy for the EFA]].
** WelcomeBackTraitor: [[spoiler: Though admittedly, she's just broken Luna out of the EFA base.]]
%% * MotionCaptureMecha: Gran Kaiser and Gran Sigma.
%% * MsFanservice: Mizuki.
%% * MysteriousWaif: Leele.
* MythArc: It takes all of both seasons for Eiji to finally find his sister Ayaka.
* OffModel: Tragically there are quite a few, mostly involving Touga's face or Mizuki's boobs.
* PigeonholedVoiceActor: Mizuki is a super busty MsFanservice, so it's not surprising that her seiyuu is Creator/YuuAsakawa.
%% * PowerCrystal
* ReallySevenHundredYearsOld: [[spoiler:Sandman's at least 400 years old and implied to have lived for millennium]].
* RedemptionEqualsDeath: Played straight when [[spoiler:Hugi dies and we find his excesses were powered by CyberneticsEatYourSoul]]; subverted [[spoiler: when Sandman tries it and gets talked down]].
* RidiculouslyHumanRobots: [[spoiler:Eina and the present-day 'Lufira']].
* {{Robeast}}: Warrior-class Zeravire.
* RocketPunch: Gravion's Graviton Pressure Punch and Sol Gravion's Graviton Tornado Punch.
* SayMyName: Occurs often, but [[spoiler:'''''"Hugi-niisan!"''''']] probably takes the cake.
%% * ShowerOfAngst: Faye gets one.
* ShoutOut: Gravion is losing badly against an enemy, when a new robot piloted by a mysterious person comes out of nowhere and saves the day. Mecha fanboy Alex immediately nicknames the newcomer "[[Anime/GreatMazinger Great Gravion]]", effectively pointing out the reference to the last episode of ''Anime/MazingerZ''.
%% * SkySurfing: G-Gradius.
* SuperPrototype: Gran Sigma, though the God Gravion itself is a prototype.
* SpyCatsuit: Mizuki wears an extremely {{Stripperific}} version, particularly noticable in [[http://img441.imageshack.us/img441/1361/80b109624fc0966909a0013.gif ''Zwei'''s OP]].
* ThisIsADrill: G-Driller and Geo Javelin. Geo Javelin's is a drill ''[[RuleOfCool on fire]]''.
* TokenMiniMoe: This series has three of them. Anya is a [[GenkiGirl genki]] CurtainsMatchTheWindow FieryRedhead with GirlishPigtails. Brigitta is just as [[GenkiGirl genki]] and has OdangoHair as well as PurpleEyes. Cecile is a RavenHairIvorySkin beauty, has CurtainsMatchTheWindow black eyes with elegant hair and [[ProperLady acts proper]] if a bit shy. All of them are {{Meido}} in Sandmann's castle. And at least the first two are quite obsessed with Eiji's "physicals". [[DirtyKid Make of that what you will]].
* TransformationNameAnnouncement: Sandman [[IAlwaysWantedToSayThat always wanted to do it once]]: [[http://www.youtube.com/watch?v=RNZfFT6qklM&feature=related&fmt=18 He gets to]].
* TransformingMecha: The Gran Troopers get the jet/robot modes.
* VictoryIsBoring: [[spoiler:Once Mizuki finished her spying job for her government, she retired to her own private resort island... and it takes about one episode to bore her with her luxury and decides to get back in action... [[BecomingTheMask this time on the side she was spying]].]]
* WhipItGood: God Gravion's Graviton Viper.
* WholesomeCrossdresser: Touga winds up in a dress more often than you'd think, and he never seems to mind.
%% * WrenchWench: Thoria.
