History VideoGame / GateKeepers

* AnIcePerson: Yukino uses the Gate of Ice and Snow, and it's one of the most potent Gates, capable of creating enormous blizzards.

%%* ChineseGirl: Feng Fei Ling (as if that's not obvious enough). Even her invocation was in mandarin.

* JerkAss: Most of the undercover Invaders are like this in their human disguise. One episode that centers around one shows that this may partly be due to stress as it was mentioned that the invader only started acting like a JerkAss shortly before the episode.

* {{Leitmotif}}: In the game each of the main female characters and some of the supporting characters have their own theme.

''Gate Keepers'' started out as a TurnBasedStrategy (with DatingSim elements thrown in) video game for the UsefulNotes/{{Playstation}} in 1999. A {{manga}} was also commissioned as well and both were released in the same month. It was later adapted into an {{anime}} series in 2000 by Creator/{{GONZO}} who decided to omit [[PutOnABus one of the main Gatekeepers]] and replace another with another character with a similar design. The setting takes place on Earth, after the end of World War II. In the middle of all that, alien creatures known simply as Invaders are infiltrating Earth and attempting to take over the world by turning humans into soulless robots. The only means to defeat the Invaders is by tapping into powerful energy locked inside dimensional "gates".

* ExpyCoexistence: Megumi is a strange case in that she coexists with the person she is expying, Misao Sakimori. [[spoiler:However, Megumi turns out to a CorruptedCharacterCopy of Misao when she pulled a FaceHeelTurn later on.]]

* LamarckWasRight: Shun's daughter Ayane inherits her gate power from him. Furthermore [[spoiler: Shun himself got his power from his father]].

* ExpyCoexistence: Megumi is a strange case in that she coexists with the person she is expying, Misao Sakimori. However, Megumi became a CorruptedCharacterCopy of Misao after she pulled a FaceHeelTurn later on.

* AnIcePerson: Yukino uses the Gate of Ice and Snow, and is one of the most potent Gates, capable of creating enormous blizzards.

%%* SexySecretary: Who also happens to be SchoolNurse.

* AlternateHistory: It's mentioned that the Invaders were first encountered in 1945. The events that transpire in the show itself, as well as the existence of AEGIS, could also count. Though by 2001 (''Anime/Gatekeepers21''), history has more or less become similar to our own, if not worse...[[spoiler: ''[[HopelessWar much worse.]]'']]

* DisappearedDad: Shun's father, [[spoiler:who died while testing a prototype Gate Engine.]] Also, Shun himself in ''Gate Keepers 21'', [[spoiler:who is revealed, in the novel, to have died fighting the Invaders.]]

* HealingHands: Ruriko's Gate of Light also permits her to heal wounds of the injured. [[spoiler:Her Inverse Gate

* GuysSmashGirlsShoot: Shun wields the Gate of Gales which is a kendo sword, while Ruriko wields the Gate of Life which is a bow and arrow.
* HeelFaceTurn: [[spoiler:Reiji Kageyama, the BigBad of the original series, is the head of A.E.G.I.S. in ''Anime/GateKeepers21''.]]
* HopelessWar: [[spoiler:As explained in ''Anime/{{Gatekeepers 21}},'' the invasion is proceeding nicely (over half of humanity has been subverted at that point), there's no way to actually win, and the very power used to fight the invaders will [[EquivalentExchange kill the users. Or worse.]] Ouch.]]
** [[spoiler:The ending, however, has the tables turn in humanity's favor, with most of the Invaders wiped out. Granted it required a ResetButton, and that the remaining ones are still in the open, but still...]]

* HumongousMecha: Five of them, actually. [[SchizoTech In 1969]].

* NewTransferStudent: Reiji Kageyama, and Satoka Tachikawa, from ''[[Anime/GateKeepers21 GK21]]''. The gatekeepers, barring Ruriko, also apply, as they all had to transfer to AEGIS's combination school/secret base when they join the team.

* ReallySevenHundredYearsOld: Yukino was born in 1169, but has stopped aging due to the effects of her Gate powers and maintains the appearance of a young girl in 1969 and 2000.

%%* {{Technopath}}: Kaiser Kikai

* UnstoppableRage: Gatekeepers who go into an UnstoppableRage gain "[[ReversePolarity Inverse Gates]]", which do the exact opposite of their original powers. This is deconstructed in ''[[Anime/GateKeepers21 GK21]]'' [[spoiler:when the BigBad, whose normal Gate power is to erase things, gets pissed off when Ayane destroys her SoulJar. The last thing she does before fading away is use her Inverse Gate, which causes [[ResetButton everything to go back the way they were]]. Satoka points out the possibility that in her anger, she forgot that the Inverse Gate does the ''exact opposite'' of the regular gate.]]

%%* ActionGirl: Ruriko, Kaoru, Yukino, Feiling. [[spoiler: And the "Ooh, intense!" girl.]]

%%* AnIcePerson: Yukino

%%* BadassNormal: Bancho has no Gate abilities, but still works with the team. [[spoiler: He becomes an EmpoweredBadassNormal by the end, with his Gate abilities awakening in the final episode.]]

%%* BarrierWarrior: Misao, in the games. Her {{expy}} Megumi, in the anime.
%%* BeachEpisode: Which is actually sort of plot relevant

%%* BlowYouAway: Shun's power, as well as that of [[LamarckWasRight his daughter Ayane]], [[spoiler:and his father]].
%%* BodyHorror: Two different types, depending on the series. In the case of ''Gate Keepers'', the Invaders were sleeper agents, some sleeping so deep that they were horrified by the realization of what they really were. In ''Anime/GateKeepers21'', the Invaders are TheVirus.

%%* BrainwashedAndCrazy: [[spoiler:Ruriko in the final arc of the series. As a result of being captured by Kageyama and Megumi before corrupting her in an effort to use her Inverse Gate of Death as part of their master plan. It gets better after Ukiya managed to snapped her back to her normal self.]]

%%* CuteBruiser: Kaoru

%%* TheDragon: Kaiser Kikai and Count Akuma.

%%* HealingHands: Ruriko

%%* LotusEaterMachine

* MasterOfIllusion: Count Akuma, and to a degree Reiko (see above).

%%* MultinationalTeam: Jim Skylark's elite group

** Also the shtick of the "Ooh, intense!" girl (whose real name is Baruko Ogawa). Over the course of no less than five {{Marilyn Maneuver}}s, more is visible each time, until we see a close-up of the front followed by her winking at the camera.
** Kaoru towards the end of "Change Towards Your Dreams". Her skirt flounces from behind as she looks back at Shun and Ruriko and runs towards the school, she's revealed not to wear sports bloomers over her white panties.

%%* PlayingWithFire: Feiling

%%* ReallySevenHundredYearsOld: Yukino

%%* TheSmartGuy: Megane

%%* SuperSpeed: Jim Skylark's Supersonic Gate.

%%* TheAnimeOfTheGame

* BerserkButton: One surefire way to piss Ruriko off is to call her a 'sniveler' (or just refer to her childhood being a sniveler). Though Shun does use it as an advantage at times.

* DayInTheLimelight: The episode, "Send Out The Gate Robo!", is a Reiko-centric episode, as it focuses on Reiko trying to find the strength of her power, as well as her place on the team, and what she contributes to it.

* DayintheLimelight: The episode, "Send Out The Gate Robo!", is a Reiko-centric episode, as it focuses on Reiko trying to find the strength of her power, as well as her place on the team, and what she contributes to it.

%%* AllYourBaseAreBelongToUs: [[spoiler: With the exception of the Commander, his secretary, and the BridgeBunnies, everybody at AEGIS HQ becomes an invader]].

%%* ChildhoodFriendRomance: Ruriko and Shun.

* ChekhovsGunman: That woman wearing the helmet and goggles [[PantyShot whose skirt always gets blown up]] is actually [[spoiler:an AEGIS undercover agent]].

%%* {{Meganekko}}: Megumi Kurogane and Misao Sakimori

* PantyShot: In the very last scene of the last episode: as Shun and Ruriko stand together watching a sunset, Ruriko's skirt blows in the wind and the camera twice gets a clear view of white panties.

* ExpyCoexistence: Megumi is a strange case in that she coexists with the person she is expying, Misao Sakimori. However, Megumi became a {{Foil}} of Misao after she pulled a FaceHeelTurn later on.

* NotSoDifferent: Megumi is jealous of Ruriko's seemingly effortless academic success, beauty, and wealth. But when [[spoiler:she turns traitor and sees inside Ruriko's mind, she realizes Ruriko actually puts a ''lot'' of effort into school because she suffers from the same self-esteem issues Megumi does]].

* EvilMakeover: Happens to [[spoiler:Kageyama]] whenever he switches to his "Shadow" identity. Inverse Gates are pure black, regardless of their original color.
