Aired in early 2005, ''Jinki:Extend'' is a HumongousMecha series, based on the manga series ''Jinki'' and its sequel ''Jinki: Extend''. At first glance, it appears to take itself seriously: A potential pilot (Tsuzaki Aoba) with no previous knowledge of the program is brought in and has to be trained in order to defend earth against the so-called Ancient Jinki. Apparently, a typical save-the-world type mecha series. However...

''Jinki:Extend'''s opening animation is a direct {{Homage}} to the opening for the first ''Anime/MobileSuitGundam'' series (0079), and there are certain Gundam-style visual cues in the mecha battles. The series also included various homages, either in the form of characters, or visual cues to several other mecha series: ''Anime/NeonGenesisEvangelion, Anime/MartianSuccessorNadesico'' , even ''Manga/KannazukiNoMiko''.

Due to this, it is difficult to say much about the series beyond the fact that its humor lies in its complete lack of originality. ''Jinki:Extend'' might not be the "Every Mecha Show Ever" series, but it certainly hits the major ones.

A VisualNovel re-imagining of the series titled ''Jinki:Extend Re:Vision'' was released on 2010. It is an eroge, however, so that's pretty much all that can be said about it on this wiki.

!!This show provides examples of:

* ActionGirl: Per the premise
* AnachronicOrder: The anime version alternates between two main story arcs set in 1998 and 2002, and also has occasional flashbacks / flashforwards to events happing elsewhen.
* AxeCrazy: Kalis Norman, PsychoForHire par excellence.
* DarkActionGirl: Shiva
* EvilMatriarch: Shizuka, Aoba's mom, certainly won't win any awards for Mother of the Year.
* ExpressiveHair (more specifically, Rui's hairclips, which look like crab pincers, can pince)
* {{Fanservice}}: Surprisingly nowhere near as much as one might expect from a series about young girls piloting giant robots. The anime averages in at about one fanservice moment per episode.
* FauxAffablyEvil: Shiva can put up a good facade of being kind and friendly, but it's just that. A facade.
* GadgeteerGenius (Aoba, borderline)
* GodivaHair (Shiva)
* GroinAttack (In the manga, one of the female characters gets wounded ''over there'' when a large, mecha-sized blade penetrates her mecha's cockpit. She survives thanks to a rescue by her teammate.)
* ImprobablyHighIQ: Elny, who according to side materials has an IQ of 300.
* LadyOfWar: Shiva is a villainous version.
* LittleMissSnarker: Rui.
* LovesTheSoundOfScreaming: Kalis in the manga. He rants about how annoyed he is that one of the girls won't scream for him while he rapes her.
* {{Otaku}} (Aoba, a plastic model otaku)
* PsychoForHire: Kalis Norman is a ''rapist'' for hire.
* RapunzelHair (Acao. It causes her problems.)
* ShrinkingViolet: Satsuki
* SinisterScythe: Used by Kalis to strip the clothes from his victims.
* SlasherSmile: Sported by Kalis, constantly, and various other villains on occasion.
* SpellMyNameWithAnS: Kalis Norman? Karis Norman? Karis Nolman? Kalis Nolman?
* TeamShot: (a direct homage to the final shot in the Gundam op, at that)
* WalkingShirtlessScene: Kalis again.
* WhiteHairBlackHeart: Kalis Norman, WalkingShirtlessScene, PsychoForHire, and all around bad guy.
