* BigBad: [[spoiler:Chairman Victor and the [[OmniscientCouncilOfVagueness High Council]] (minus [[TokenGoodTeammate Li]])]] are the ones responsible for [[BigCreepyCrawlies the Blue]] [[spoiler:by screwing up the Earth badly enough to bring about GaiasVengeance, and are doing everything in their power to escape justice]]. Around the end of the series [[spoiler:they are killed by the Blue and [[TheStarscream Seno]] [[DragonAscendant Miyagi]] takes over as Big Bad, trying to keep humanity from returning to Earth]].

* HollywoodTactics: The High Council and several higher-ups invoke this trope, leading to death that could have been avoided.

* HumansAreTheRealMonsters: A major theme of the series is that, in their attempt to survive, pretty much every human being has become cold and unfeeling, placing ''absolutely no'' value in human life, love, or simple compassion [[ForTheGreaterGood since everyone is viewed as expendable]]. [[ActionGirl While Marlene is certainly capable of handling herself,]] [[EmotionlessGirl she's not an especially warm]] [[IceQueen or likable character]]. [[spoiler:As she begins to change through [[TheCutie Yuji's]] influence, the tables are turned when [[WideEyedIdealist Yuji]] [[BreakTheCutie becomes]] [[BrokenBird like Marlene was]] at the beginning of the series, and she has to [[LoveRedeems save him]] from [[SanitySlippage going completely insane]]. Yuji himself takes the mindset from pretty much every other human being living at that point.]] And by the end, it’s revealed that [[spoiler:human overpopulation and technology [[GaiasVengeance was what spawned the Blue in the first place]]]].

* LuddWasRight: [[spoiler:The show basically posits civilization (i.e. pretty much everything after the introduction of agriculture and the wheel) as against Man's true harmony, and blames humanity and technology for the rise of [[BigCreepyCrawlies the Blue]], which was created to [[GaiasVengeance restore the natural world]]. Of course, this is done by showing how depraved and screwed-up life on the technologically advanced [[SpaceColony Second Earth]] is compared to those who [[InTouchWithNature "embrace" nature]].]]

* LuddWasRight: [[spoiler:Technology created the Blue, and in the end is wiped out.]]

The premise is similar to that of ''Literature/StarshipTroopers'' but without the campy satirical feel of [[Film/StarshipTroopers the film]] or the controversial political ideology of [[Literature/StarshipTroopers the novel]]. Creator/AdultSwim even described this show as ''Starship Troopers'' meets ''WesternAnimation/{{Futurama}}.'' See also ''Anime/EarthMaidenArjuna'' for a similar series.

Around the end of the series [[spoiler:they are killed by the Blue and [[TheStarscream Seno]] [[DragonAscendant Miyagi]] takes over as Big Bad, trying to keep humanity from returning to Earth]].

* ScienceIsBad: [[spoiler:The Aesop is that [[FamilyUnfriendlyAesop humanity should never have advanced beyond an agricultural society]], as the Blue are wiping out humans because they have overpopulated and caused pollution with their technology.]]

Yuji Kaido was an ordinary young man with a normal lifestyle but after being diagnosed with a strange and terminal illness, doctors suggested that he and other similar individuals be [[HumanPopsicle frozen]] and awaken after a proper cure for the disease has been found. This was in 2009. Flash to the year 2031, Yuji awakes to a world that has been completely taken over by a giant insect-like species known as the Blue. Yuji is only saved from certain death by the beautiful but cold soldier, Marlene Angel. Together, both characters must find a way to survive onslaught after onslaught of the Blue and make it back to a space station called Second Earth, where Yuji must discover the true nature of his condition. Along the way, Yuji and Marlene form a bond with one another, one that starts off as hostile but gradually evolves into trust, friendliness and, ulimately, love.

* BigBad: Victor and the [[OmniscientCouncilOfVagueness High Council]], since they screwed up the Earth badly enough to bring about GaiasVengeance.

* BreakTheCutie: [[spoiler: Alica, whose introduced as bubbly and optimistic. Then she happens upon Tony in a Blue's nest and her attitude changes rapidly.]]

* BrokenAesop: [[spoiler: "Take to the stars to ease the planet's burden? Screw you! GreenAesop or death!"]]
* BrokenBird: Marlene [[spoiler:and later Yuji, for a time]].

** Yuji starts the series naive about his new circumstances and is a bit of a pushover. As he goes through his hellish experiences, he learns to become more assertive and becomes a worthwhile leader. His fiery emotions manages to thaw Marlene's icy exterior, leading her to discover her humanity again.
** Marlene starts off as cold and as ruthless as any other Second Earth citizen; apathetic to the suffering of others, only caring about the "mission" (wiping out the Blue) and remorseless in her actions. As she starts to hang around Yuji and sees his drive and compassion for others, this starts to slowly get through to her and she begins to doubt everything she ever believed in. By middle of the series, while still ruthless, her demeanor has softened considerably and she is hell bent on staying near Yuji, aiding him in all his trials. By series end, she has completely fallen for Yuji and adopted a motherly side towards children, [[spoiler:hinting at her pregnancy with Yuji's child]].

* ClaspYourHandsIfYouDeceive: Victor, Chairman of the High Council.
* ColdSleepColdFuture: Most of the characters here are heartless bastards who place little if any value on human life to the point where civilians who are not granted access to Second Earth are not only expendable but are pretty much considered dead to those who are on Second Earth. The one and only thing on everyone's mind is wiping out the Blue, and that's it.

* GaiasVengeance: The Earth creates the Blue because the human race has become overpopulated and because of their negative impact on the environment.
** Gaia waited for humans to make the Blue while trying to cure a disease, then directed them to kill them, Then when that fails, she kills only the Blue and drives all the humans in space insane.

* GeniusLoci: Gaia.

* GreenAesop: Technology and its abuse of it caused the Earth to punish humans by siccing the Blue on them.
* HeWhoFightsMonsters: Yuji briefly becomes this after fighting the Blue for so long/after his B-cells awaken.
** HumansAreTheRealMonsters: He takes the mindset from pretty much every other human being living at that point.

* HumansAreTheRealMonsters: A major theme of the series is that, in their attempt to survive, pretty much every human being has become cold and unfeeling, placing ''absolutely no'' value in human life, love, or simple compassion [[ForTheGreaterGood since everyone is viewed as expendable]]. [[ActionGirl While Marlene is certainly capable of handling herself,]] [[EmotionlessGirl she's not an especially warm]] [[IceQueen or likable character]]. [[spoiler: As she begins to change through [[TheCutie Yuji's]] influence, the tables are turned when [[WideEyedIdealist Yuji]] [[BreakTheCutie becomes]] [[BrokenBird like Marlene was at the beginning of the series,]] [[LoveRedeems and she has to save him from]] [[SanitySlippage going completely insane.]]]]

* IKEAErotica: Intentional. The war with the Blue has destroyed human intimacy, and sex is a mechanical, meaningless act. Episode 24 subverts this when [[spoiler:Yuji and Marlene sleep with one another, an act that both parties go into willingly and lovingly]].
* ILetGwenStacyDie: [[spoiler: A major part of [[TheWoobie Yuji's]] CharacterDevelopment is how completely powerless he is to prevent the deaths of anyone close to him. [[BreakTheCutie This doesn't do much good to]] [[BrokenBird his already hurting mental state,]] as 'hurting' swiftly becomes [[SanitySlippage 'rapidly]] [[AxeCrazy deteriorating.']] [[LoveRedeems Marlene of all people is the one to finally snap him out of it.]]]]

* JerkassHasAPoint: Han, who was willing to abandon humanity and run away with a beautiful Sleeper woman, chews out his superiors about their attitudes towards Sleepers in general:

%%* LuddWasRight:

* MechaTropes: Being a mecha series, it full of these.

* OfficialCouple: Yuji and Marlene. One of the major factors in this series is showing the development of their relationship from beginning to end.
** [[spoiler: More [[JustifiedTrope justified]] than most, as the fact that Marlene is falling in love with Yuji is a telling sign she's being humanized more and more through Yuji's influence. Her behavior comes to clash with [[TheOmniscientCouncilOfVagueness her superiors,]] [[HeWhoFightsMonsters who are so absorbed in fighting Blue]] that they do not seem to be able to even ''comprehend what love is anymore.'']]
* TheOmniscientCouncilOfVagueness: The High Council, complete with a [[Anime/NeonGenesisEvangelion Gendo Ikari]] [[{{Expy}} look alike]].

* ARealManIsAKiller: [[spoiler: [[TookALevelInBadass The more of a badass Yuji becomes,]] [[HeWhoFightsMonsters the less benevolent he comes off as.]]]]

* LaResistance: The Ark, formed by Seno, who seeks to overthrow the corrupt and arrogant High Council.

* ScienceIsBad: Whether or not this trope is in effect depends on whether the Blue are wiping out humans [[spoiler:because we have technology/cause pollution, or because we've overpopulated.]]
* StuffedIntoTheFridge: In the very first episode, Yuji is seen eyeing an unnamed, attractive female sleeper. It seems like she might be set to provide a companion in the future to whom he can relate, until [[spoiler:he finds her body twisted into a Blue cocoon]], establishing that AnyoneCanDie. [[spoiler: And wouldn't you know, by the end of the ''third'' episode, everyone save for [[WideEyedIdealist Yu]][[TheLoad ji]] and [[ActionGirl Mar]][[EmotionlessGirl lene]] [[EverybodysDeadDave is dead.]] Most of the supporting characters didn't even make it past episode ''two.'']]
* ThemeMusicPowerUp: Happens in the last episode, [[spoiler:when the last survivors of technological humanity in orbit FreakOut en masse and destroy themselves in a stampede back to earth, completing GaiasVengeance]].
* TooGoodForThisSinfulEarth: [[spoiler: Yung.]]

* TheVirus: The B-cells, of course.

* WouldntHitAGirl: Again with Victor, the High Council chairman.
* YankTheDogsChain: After weeks of {{Everything Trying To Kill| You}} Marlene, she finally brings back the mission objective that cost everyone else their lives. For that she gets reprimanded by OminousMultipleScreens, busted down to bottom rank, and stonewalled for any information on the man she may or may not have saved.

The premise is similar to that of ''Literature/StarshipTroopers'' but without the campy satirical feel of [[Film/StarshipTroopers the film]] or the political ideology of [[Literature/StarshipTroopers the novel]]. Creator/AdultSwim even described this show as ''Starship Troopers'' meets ''WesternAnimation/{{Futurama}}.''

* BabiesEverAfter[=/=]HappilyEverAfter: Yes, despite the overall tone of the series, it does end on a rather happy note [[OnlyTheLeadsGetAHappyEnding for the main characters]]. [[spoiler: Yuji ensures that the threat to humanity is over, and then reunites with Marlene, with the promise that they can live a happy life together on Earth. Marlene is pregnant with Yuji's child]].

* BigBad: Victor and the [[OmniscientCouncilOfVagueness High Council]] are ''supposed'' to be this, since they screwed up the Earth badly enough to bring about GaiasVengeance, but [[DesignatedVillain their goal to protect humanity is very reasonable and heroic]]- instead, ''Gaia'', nominally the BigGood, [[DesignatedHero comes off as this]] since she created [[BigCreepyCrawlies The Blue]] and attempted to wipe out humanity and, in the ending, [[spoiler:[[TheBadGuyWins successfully wiped out technology]]]].

** Gaia waited for humans to make the Blue while trying to cure a disease, then directed them to kill them, Then when that fails, she kills only the Blue and drives all the humans in space insane. [[GodIsEvil So not only]] [[DesignatedHero is she a bitch]], [[TheGodsMustBeLazy she's lazy too]].

* GeniusLoci: Gaia the DesignatedHero.

* HumansAreTheRealMonsters: A major theme of the series is that, in their attempt to survive, pretty much every human being has become cold and unfeeling, placing ''absolutely no'' value in human life, love, or simple compassion [[ForTheGreaterGood since everyone is viewed as expendable]]. [[ActionGirl While Marlene is certainly capable of handling herself,]] [[EmotionlessGirl she's not an especially warm]] [[IceQueen or likable character]]. [[spoiler: As she begins to change through [[TheCutie Yuji's]] influence, the tables are turned when [[WideEyedIdealist Yuji]] [[BreakTheCutie becomes]] [[BrokenBird like Marlene was at the beginning of the series,]] [[LoveRedeems and she has to save him from]] [[SanitySlippage going completely insane.]]]] Exaggerated to absurd extremes when the humans who ''actually try to leave the planet alone'' [[DesignatedVillain are treated as the embodiment of human evil]].

* LuddWasRight: Gets [[BrokenAesop broken]] by how [[StrawmanHasAPoint the group that plans on using technology to reduce the strain on earth]] is [[DesignatedVillain demonized instead of considered]].

* TheOmniscientCouncilOfVagueness: The High Council, complete with a [[Anime/NeonGenesisEvangelion Gendo Ikari]] [[{{Expy}} look alike]]. However, [[DesignatedVillain they aren't as bad as some examples]], and their motives are eventually made clear, [[spoiler:using the Sleepers to defeat the Blue]].

** Gaia waited for humans to make the Blue while trying to cure a disease, then directed them to kill them, Then when that fails, she kills only the Blue and drives all the humans in space insane, what a girl. [[GodIsEvil So not only]] [[DesignatedHero is she a bitch]],[[TheGodsMustBeLazy she's lazy too.]]

* TheOmniscientCouncilOfVagueness: The High Council, complete with a [[Anime/NeonGenesisEvangelion Gendo Ikari]] [[{{Expy}} look alike]]. However, they aren't as bad as some examples, and their motives are eventually made clear, [[spoiler:using the Sleepers to defeat the Blue]].

* AttackItsWeakPoint: The core, the small fleshy tube on a Blue's head; shoot it [[MemeticMutation FOR MASSIVE DAMAGE!]].
* AxCrazy: Using [[strike: [[Anime/MobileSuitGundam Newtype]]]]B-Cell powers tends to result in this. Tony completely gives into his madness. Yuji was on the verge of it until he's saved by Marlene.
* BabiesEverAfter[=/=]HappilyEverAfter: Yes, despite the overall tone of the series, it does end on a rather happy note for the main characters. [[spoiler: Yuji ensures that the threat to humanity is over, and then reunites with Marlene, with the promise that they can live a happy life together on Earth. Marlene is pregnant with Yuji's child]].

* BigCreepyCrawlies: The Blue, obviously

* BrokenBird: Marlene [[spoiler:and later Yuji, for a time.]]
* BugWar [[spoiler: The Blue are more or less created by the humans, in fact, because humans wanted to use B-cells for war. This backfires on them spectacularly]].
* CelibateHero: Interestingly, despite the [[IKEAErotica attitude towards sex and love in this world]], both times Marlene is presented in such a situation [[spoiler: prior to having sex with Yuji]], the male involved in the situation only gets so far as groping her before she stops them from going further. In the first occurrence, she's not in the mood. In the second, adding to the previous reason, by that point she'd fallen in love with Yuji. Additionally, this may be in part due to her backstory, in that she was forced to discover about such things at an unfortunately young age, and ended up deeply hurt as a result.

** Marlene starts off as cold and as ruthless as any other Second Earth citizen; apathetic to the suffering of others, only caring about the "mission" (wiping out the Blue) and remorseless in her actions. As she starts to hang around Yuji and sees his drive and compassion for others, this starts to slowly get through to her and she begins to doubt everything she ever believed in. By middle of the series, while still ruthless, her demeanor has softened considerably and she is hell bent on staying near Yuji, aiding him in all his trials. By series end, she has completely fallen for Yuji and adopted a motherly side towards children, [[spoiler:hinting at her pregnancy with Yuji's child.]]

* ClaspYourHandsIfYouDeceive Victor, Chairman of the High Council.

* CommonTongue: for all the efforts at realism, everyone living in the future speaks the same language, no matter how geographically isolated.
* CrapsackWorld: It's a world where anyone can be eaten by giant bugs and humans with the capacity to save the Earth are assholes. Yeah, this world sucks. Thankfully, by series end, the Earth takes its several steps toward recovery.

* DeadlyDodging: In ''The Warrior'' Marlene kills two Maneaters (praying mantis-esque Blue) by evading their attacks and causing one of them to ''impale the other.'' She skewers the second one with her bayonet at the same time.
* DeadpanSnarker: All of the main characters and a fair few side characters have their moments...
* DefrostingIceQueen: Marlene, Marlene, Marlene.
* EarnYourHappyEnding: After all the hell our two main leads go through, Yuji and Marlene has certainly earned it. [[spoiler:Yuji ensures Earth is saved by "communicating" with Gaia and Marlene reunites with Yuji, content that they can finally live in peace and looking forward to raising their child.]]
* FaceHeelTurn: [[spoiler: Tony, after completely giving into his madness. Alicia as well, though she manages to snap out of it. Unfortunately, it's not enough to save her...]]
* {{Fanservice}}: Some very...random sexual encounters. Marlene is the main source of this trope for the series, appearing naked on the ending credits, throughout the show and on the VHS/DVD/Blu-Ray covers.

* FreudianTrio: After most of the recovery team are killed, Yuji becomes TheId, Joey (and to a lesser degree, Robert) become TheEgo, and Marlene becomes TheSuperego in the dynamic of the remaining members. [[spoiler: After Joey and Robert die, Yuji and Marlene predictably begin to wear on each other's nerves, establishing their initial dynamic, with each of them improving through the other's influence. Yuji's ShrinkingViolet tendencies become less pronounced, [[TookALevelInBadass learning to take the lead once in a while and fend for himself,]] and Marlene becomes [[DefrostingIceQueen less and less of a]] [[EmotionlessGirl coldhearted]] [[IceQueen bitch,]] opening up a bit more and embracing her more human side, although it takes a little bit more time for her to actually [[TookALevelInKindness take a level in kindness.]]]]

** Gaia waited for humans to make the Blue while trying to cure a disease, then directed them to kill us. Then when that fails, she kills only the Blue and drives all the humans in space insane, what a girl. [[GodIsEvil So not only is she a bitch,]] [[TheGodsMustBeLazy she's lazy too.]]
* GainaxEnding: Yuji somehow [[spoiler:communicates with Gaia and convinces her to let the humans and Blue live on Earth in peace. While he reunites with Marlene and their unborn child, Second Earth citizens suddenly go insane and wipe themselves out.]]

* HumansAreTheRealMonsters: A variant. A major theme of the series is that, in their attempt to survive, pretty much every human being has become cold and unfeeling, placing ''absolutely no'' value in human life, love, or simple compassion [[ForTheGreaterGood since everyone is viewed as expendable.]] [[ActionGirl While Marlene is certainly capable of handling herself,]] [[EmotionlessGirl she's not an especially warm]] [[IceQueen or likable character.]] [[spoiler: As she begins to change through [[TheCutie Yuji's]] influence, the tables are turned when [[WideEyedIdealist Yuji]] [[BreakTheCutie becomes]] [[BrokenBird like Marlene was at the beginning of the series,]] [[LoveRedeems and she has to save him from]] [[SanitySlippage going completely insane.]]]]

* IKEAErotica: Intentional. The war with the Blue has destroyed human intimacy, and sex is a mechanical, meaningless act. Episode 24 subverts this gloriously when [[spoiler:Yuji and Marlene sleep with one another, an act that both parties go into willingly and lovingly.]]

* InfantImmortality: Averted. Poor [[spoiler:Yung]].

* TheLoad: In the beginning, [[EverythingTryingToKillYou everything is trying to kill Marlene.]] Let's just say [[NonActionGuy Yuji]] doesn't exactly make keeping the two of them alive easy.
* LuddWasRight: Gets [[BrokenAesop broken]] by how [[StrawmanHasAPoint the group that plans on using technology to reduce the strain on earth]] is [[DesignatedVillain demonized instead of considered.]]
* MakingLoveInAllTheWrongPlaces: Okay, you may die tomorrow, or even today. Sure, you got IKEAErotica going on, but in the middle of a transmission back to base? Right before a Blue attack?

* MasculineGirlFeminineBoy: Marlene and Yuji, so much so that [[spoiler: Yuji totally qualifies as a BrokenBird.]]

* TheOmniscientCouncilOfVagueness: The High Council, complete with a [[Anime/NeonGenesisEvangelion Gendo Ikari]] [[{{Expy}} look alike]]! However, they aren't as bad as some examples, and their motives are eventually made clear, [[spoiler: using the Sleepers to defeat the Blue.]] There's a bit more to it than that, however.

** Possibly justified, as most of the guards heard about that through their radios; aside from, say, height and hair color, they'd have no way of knowing what she looked like.
* PregnantBadass: [[spoiler: Marlene's in the (very) early stages during the last two episodes]].

* ARealManIsAKiller: Deconstructed. [[spoiler: [[TookALevelInBadass The more of a badass Yuji becomes,]] [[HeWhoFightsMonsters the less human he comes off as.]]]]

* StuffedIntoTheFridge: In the very first episode, Yuji is seen eyeing an unnamed, attractive female sleeper. It seems like she might be set to provide a companion in the future to whom he can relate, until [[spoiler:he finds her body twisted into a Blue cocoon]].
** Justified in that it establishes that AnyoneCanDie.[[spoiler: And wouldn't you know, by the end of the ''third'' episode, everyone save for [[WideEyedIdealist Yu]][[TheLoad ji]] and [[ActionGirl Mar]][[EmotionlessGirl lene]] [[EverybodysDeadDave is dead.]] Most of the supporting characters didn't even make it past episode ''two.'']]

Now has a character page looking for some kind souls to contribute to its growth!

* AdaptationExplanationExtrication: In the series, the Clincher shows up in the Baikonur power room, kills Han by fusing to him, takes a few bullets and appears to be dead, but [[NotQuiteDead follows the gang into the shuttle when they escape.]] In ''Blue Gender: The Warrior'', the scene in the power room is cut, so suddenly, this thing appears on the shuttle, fused to Han's body, with no explanation whatsoever.

--->Han: Shut up! You guys are all alike! Whatever suits you, military order...you're nothing more than vermin to see everything in those terms! How are they Samples? How are they guinea pigs? She is just like us! She's a human, with the same red blood flowing through her as us! And yet...and yet, am I right? All that waits for her are ruins and bugs, and your egos! You, who would cast her out into a world more rotten than Hell itself, and carve her up with the tainted blade that is reality! Do you think she would be happy with something like that? Don't you feel sorry for the Sleepers? I will protect you! I will...I will...For her life! For her future! For her peace of mind! You'll pay! You'll pay for this!!!

Yuji Kaido has been [[HumanPopsicle frozen]] since 2009 after being diagnosed with a strange and terminal illness to be awakened after a proper cure for his disease has been found. He is awakened to the year 2031 to a world that has been completely taken over by a giant insect-like species known as the Blue. He and Marlene Angel must find a way to survive onslaught after onslaught of the Blue and make it back to a space station called Second Earth, where Yuji must discover the true nature of his condition. In many ways it is a FishOutOfWater plot, but without the humor as Yuji wakes up to a world completely different and is at first unable to cope with a world in which the Blue have taken over. He does quickly learn to fend for himself, but is still shocked by how the ethics, morality, values, and general outlook on life have changed so radically since his time. For example, sex is meaningless pleasure, and there's no point in forming close meaningful bonds because AnyoneCanDie at any moment. [[ColdSleepColdFuture There is no longer any value placed on human life as every individual human is considered expendable]].

* AfterTheEnd
* AlternateContinuity: ''Blue Gender: The Warrior'' cuts up various bits of the anime and condenses/mangles it into a 100 minute movie with vague similarities.

* TheOmniscientCouncilOfVagueness - The High Council, complete with a [[Anime/NeonGenesisEvangelion Gendo Ikari]] [[{{Expy}} look alike]]! However, they aren't as bad as some examples, and their motives are eventually made clear, [[spoiler: using the Sleepers to defeat the Blue.]] There's a bit more to it than that, however.
* PaperThinDisguise - In episode 14, Marlene is able to evade ([[TheGuardsMustBeCrazy apparently]]) trained guards and [[EvilChancellor High Council members]] by letting her hair down and putting on a medic's uniform.

* LaResistance - The Ark.
* SamusIsAGirl - Marlene gets one of these with Yuji, who is as surprised to find that she's human. Naturally they become the closest this series can have to a LoveInterest.

* SceneryGorn - Plenty of footage of destroyed cityscapes covered by Blue nests.
* ScienceIsBad - Whether or not this trope is in effect depends on whether the Blue are wiping out humans [[spoiler:because we have technology/cause pollution, or because we've overpopulated.]]
* ThemeMusicPowerUp - Happens in the last episode, [[spoiler:when the last survivors of technological humanity in orbit FreakOut en masse and destroy themselves in a stampede back to earth, completing GaiasVengeance.]]
* {{Tuckerization}} - Yuji's friend Takashi, named after one of the producers
* StuffedIntoTheFridge - In the very first episode, Yuji is seen eyeing an unnamed, attractive female sleeper. It seems like she might be set to provide a companion in the future to whom he can relate, until [[spoiler:he finds her body twisted into a Blue cocoon]].

* VaginaDentata- The Blue.
* TheVirus - The B-cells, of course.

* WouldntHitAGirl - Again with Victor, the High Council chairman.
* YankTheDogsChain - After weeks of {{Everything Trying To Kill| You}} Marlene, she finally brings back the mission objective that cost everyone else their lives. For that she gets reprimanded by OminousMultipleScreens, busted down to bottom rank, and stonewalled for any information on the man she may or may not have saved.
* ZergRush - Partial example, since individual Blue are hardly weak, but they do tend to attack in huge numbers.

* AGodAmI- [[spoiler:Tony]], who declares that upon [[spoiler:[[OmnicidalManiac wiping out humanity]]]], he will "become the world's Messiah!"

* AMechByAnyOtherName: Armor Shrike is a fancy name for MiniMecha.

* ARealManIsAKiller: Deconstructed. [[spoiler: [[TookALevelInBadass The more of a badass Yuji becomes,]] [[HeWhoFightsMonsters the less human he comes off as.]]]]

* LaResistance - The Ark.

* TheVirus - The B-cells, of course.

* WouldntHitAGirl - Again with Victor, the High Council chairman.

The premise is similar to that of ''Literature/StarshipTroopers'' but without the campy satirical feel of [[Film/StarshipTroopers the film]] or the political ideology of [[Literature/StarshipTroopers the novel.]][[note]]Creator/AdultSwim even described this show as ''Starship Troopers'' meets ''Futurama''.[[/note]] Unlike most anime, Blue Gender has very little humor and cuteness is nonexistent, though there is plenty of {{fanservice}} and other sexual moments (most of which has been heavily censored when aired on Creator/CartoonNetwork's Adult Swim line-up. The reason for this is because, at the time, Toonami was a weekday afternoon line-up and ''Blue Gender'' was supposed to appear there. When it was announced that Creator/AdultSwim would be airing the show, no effort was made to re-edit the show to Adult Swim standards). The series generally has a very dark and [[SlidingScaleOfIdealismVersusCynicism cynical]] tone; however, the series does end with the message that humanity can live happily (Provided they live in harmony with the Earth).

The series has very in-depth character development on the parts of both Yuji and Marlene, who end up being completely different people by the end of the anime's 26-episode run than they were in the beginning.

* AGodAmI / DarkMessiah - [[spoiler:Tony]], who declares that upon [[spoiler:[[OmnicidalManiac wiping out humanity]]]], he will "become the world's Messiah!"
** Apparently he didn't think his plan through very well. [[AlternateCharacterInterpretation Alternately,]] he's just [[AxCrazy totally fucking nuts.]]

* BabiesEverAfter[=/=]HappilyEverAfter: Yes, despite the overall tone of the series, it does end on a rather happy note for the main characters. [[spoiler: Yuji ensures that the threat to humanity is over, and then reunites with Marlene, with the promise that they can live a happy life together on Earth. And Marlene is pregnant with Yuji's child]].

* BadAss - Marlene, several other characters earn mention as well, including Dice and even Tony (for his freakish skill in a Shrike, at any rate).
