4	''Gate Keepers'' started out as a TurnBasedStrategy (with DatingSim elements thrown in) video game for the Platform/{{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".
5
6	That's where a secret agency known as A.E.G.I.S, short for "Alien Exterminating Global Intercept System," comes in. They seek out people known as Gate Keepers, who have the ability to unlock the gates, which in turn gives them superhuman powers. The protagonist, Shun Ukiya, is one of the Gate Keepers, who becomes aware of his powers after witnessing a fight between the Invaders and a schoolmate -- and childhood friend -- Ruriko Ikusawa. The story goes on to include other Gate Keepers and their exploits as they fight against the Invaders in their bid to defend Earth.
7
8	It also spawned a sequel, ''Anime/{{Gate Keepers 21}}'', set [[NonIndicativeTitle 31]] years later. There is also a novel, set in 1985, which helps explain some of the events between the two anime series.

12	----
13	!!''Gate Keepers'' contains examples of:
14
15	* ActionGirl: Each female member of the main cast can definitely hold their own against the Invaders. [[spoiler:And when push comes to shove, the "Ooh, intense!" girl is also seen packing some firepower.]]
16	%%* TheAce: Jim Skylark.
17	* AdaptedOut: Francine, who was one of the main Gatekeepers in the game, was completely omitted in the anime.
18	%%* AllAmazonsWantHercules: [[spoiler: Kaoru and Bancho, after he gets his own Gate ability [[BirdsOfAFeather which is very similar to hers]].]]
19	* AllYourBaseAreBelongToUs: With the exception of the Commander, his secretary, and the BridgeBunnies, [[spoiler:everybody at AEGIS HQ becomes an invader, forcing them to make an escape]].
20	* 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.
21	%%* AnimeChineseGirl: Feng Fei Ling (as if that's not obvious enough). Even her invocation was in mandarin.
22	* ArtisticLicenseHistory: Lampshaded when an invader craft patterned after a Boeing 747 shows up at an airport, While the plane was already in production, the fact that it's even there ahead of its scheduled flight clues the Gatekeepers in that it's an enemy.
23	* AwesomeButImpractical: Reiko's gate power is very effective, able to take out hordes of invaders at once, but it depends on her having a musical instrument (often a grand piano that can easily be destroyed).
24	* BadassNormal: Bancho has no Gate abilities, but does his best to help the team with his brute strength. [[spoiler: He becomes an EmpoweredBadassNormal by the end, with his Gate abilities awakening in the final episode.]]
25	* BaitAndSwitchCredits: Subverted. One scene from the OP apparently depicts Megumi firing a ki blast from her hand (which is naturally impossible due to the nature of her powers, and thus, wouldn't happen). It turns out she was using her powers to ''block'' that energy blast, not to produce it.
26	* BarrierWarrior: Misao, in the games, wields the Gate of Walls to generate barriers to block attacks. In the anime, Megumi uses these same powers.
27	* BeachEpisode: Invoked as part of the LotusEaterMachine in episode 10 as Count Akuma encourages each of the cast to indulge in their desires.
28	%%* TheBigGuy: Bancho
29	* BlowYouAway: Shun wields the Gate of Wind and uses it with his kendo skills. [[spoiler:It's eventually revealed that his father had the same power.]]
30	* 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.
31	%%* BoisterousBruiser: Bancho.
32	* BrainInAJar: Count Akuma's brain is in, for lack of a better word, a fishbowl.
33	* BrainwashedAndCrazy: [[spoiler:Through Megumi's corruption, Ruriko's spirit breaks in the final few episodes and it manifests as her Inverse Gate of Genocide.]]
34	* CallingYourAttacks: On top of the usual "Gate Open!" invocation, every attack by their user is named.
35	* CanonForeigner: Megumi is an anime-only character. As is Bancho, who unlike Megumi, isn't even based on a character from the game.
36	%%* TheCavalry: Jim and his team in the final episode.
37	* ChekhovsGunman: That woman wearing the helmet and goggles [[MarilynManeuver whose skirt always gets blown up]] is actually [[spoiler:an AEGIS undercover agent]].
38	* ChildhoodFriendRomance: Ruriko and Shun are childhood friends and become a couple at the end of the anime. [[spoiler:According to the sequel, however, it doesn't last.]]
39	* ChuckingChalk: In the anime adaptation, there was a particularly JerkAss teacher who often threw chalk at students. Said teacher also happened to be an Invader sleeper agent [[BecomingTheMask who got convinced that he was really a human by his own disguise]].
40	%%* CoolShades: The AEGIS Commander [[spoiler: as well as Reiji, when ''he'' becomes the new AEGIS Commander]]
41	* CrazyPrepared: AEGIS just happens to have a giant piano for the Gate Robot in case Reiko decides to pilot it instead of Shun.
42	* ADayInTheLimelight: 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.
43	* {{Delinquents}}: Shun and Ruriko disguise themselves as delinquents (Shun wearing his uniform in disarray, Ruriko dressing like a ''sukeban'' with a long skirt and curly hair) in order to confront Bancho -- whose nickname itself is Japanese for "delinquent."
44	* DeliberateValuesDissonance: Downplayed, but the anime also touches upon both the social norms of 1960s Japan and the radicalism among the youth at that time [[spoiler:which Reiji exploits in order to declare himself Prime Minister]].
45	* DisappearedDad: Shun's father, [[spoiler:who died while testing a prototype Gate Engine.]]
46	* TheDitz: Reiko, though this might be out of trauma after her parents's divorce.
47	* TheDragon: Kaiser Kikai and Count Akuma are elite Invaders under Reiji's command, and are a notch above the rank-and-file Invaders.
48	* DrivenByEnvy: Ruriko is popular, beautiful, rich and kind. Megumi is socially-inept, plain-looking, middle-low class and embittered. [[spoiler: Guess which one pulls a FaceHeelTurn?]]
49	* EveryoneCallsHimBarkeep: The Commander. His name is revealed in the [[AllThereInTheManual novel]].
50	%%* EvilCounterpart: "Shadow"
51	* EvilCostumeSwitch: Happens to [[spoiler:Kageyama]] whenever he switches to his "Shadow" identity. Inverse Gates are pure black, regardless of their original color.
52	* ExpyCoexistence: Megumi is a strange case in that she coexists with the person she is expying, Misao Sakimori. [[spoiler:However, Megumi turns out to be a CorruptedCharacterCopy of Misao when she pulled a FaceHeelTurn later on.]]
53	* FaceHeelTurn: [[spoiler:Megumi Kurogane, due to her ''massive'' case of being DrivenByEnvy, specifically her envy towards Ruriko.]]
54	* FunWithAcronyms: '''A'''lien '''E'''xterminating '''G'''lobal '''I'''ntercept '''S'''ystem.
55	* GenkiGirl: Francine although she doesn't reach the heights that many of the other characters do for the trope and can be very serious when she wants to be but her goal in life is to make one thousand friends.
56	* GratuitousEnglish: Any American character who isn't part of Jim's team. Also Francine from the game.
57	* GuysSmashGirlsShoot: Shun wields the Gate of Wind to augment his kendo skills, while Ruriko's Gate of Life lets her shoot light-empowered arrows.
58	* HealingHands: Ruriko's Gate of Life also permits her to heal wounds of the injured.
59	%%* TheHeartless: The Invaders
60	* HowDoIShotWeb: Shun struggles in every episode to learn how to use his ability properly.
61	* HumongousMecha: [[SchizoTech In 1969]], AEGIS has managed to manufacture Gate Robots, powered by Gate Engines to further amplify the pilot's powers.
62	* AnIcePerson: Yukino uses the Gate of Ice and Snow, and it's one of the most potent Gates, capable of creating enormous blizzards.
63	* InstantFanClub: Reiji has at least three girls as members of an actual club that he started.
64	* {{Invocation}}: "Gate! Open!"
65	* {{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.
66	** Also Megumi. While not an invader [[spoiler: she does pull a FaceHeelTurn later on.]]
67	* LadyOfWar: Ruriko, who uses arrows, as opposed to Kaoru, who uses her [[CuteBruiser fists]].
68	* LamarckWasRight: [[spoiler: Shun got his power from his father]].
69	* {{Leitmotif}}: In the game, each of the main female characters and some of the supporting characters have their own theme.
70	* LotusEaterMachine: The Demon Duke traps the cast in one of these in episode 10.
71	* MagicMusic: Reiko's Gate power is focused on her piano playing, which creates beautiful illusions for people... and acts as a BrownNote for invaders.
72	* MarilynManeuver: Reiko, as her skirt always flows whenever she gets ready to unleash her sound attack.
73	** A RunningGag with Agent Ogawa, a.k.a. the "Ooh intense!" girl.
74	* MasterOfIllusion: Reiko's Gate of Illusion can create illusions, and her music is [[BrownNote harmful to Invaders]]. Count Akuma also uses illusions to sway the hearts of his victims.
75	* MeaningfulName: The Commander's name has something to do with his ability to manipulate time.
76	* MultinationalTeam: Jim Skylark's elite group consists of Jim himself (British), Jun (American), and Misao (Japanese-German).
77	* MusicalAssassin: Reiko can use her powers when she's playing music, so...
78	* NewEraSpeech: [[spoiler:Once Kageyama takes over and declares himself Prime Minister]].
79	* NewTransferStudent: The Gatekeepers, barring Ruriko, all had to transfer to AEGIS's combination school/secret base when they join the team.
80	* TheOmniscientCouncilOfVagueness: Comes as either the invader leaders, or the group of AEGIS commanders.
81	* PaperThinDisguise: It's inexplicable how no one realized Kageyama was their enemy when all he puts on for disguise is a pair of shades (which he carries around everywhere anyway) and a little unbuttoning of his shirt.
82	* ParentalAbandonment: Shun's resentment of his dead father; Kaoru, Reiko, Megane, Big Boss and Feiling have no visible parents (Reiko's are divorced); Yukino's parents died some eight hundred years ago. Averted by Ruriko's intact and happy family. Possibly subverted by Megumi's apparent desire that her own parents would just go away and die somewhere.
83	* PlayingWithFire: Francine (a game-only character) uses the Gate of Heat and Explosion. Feiling instead uses this kind of Gate in the anime, though its attributes are merged with her original Gate of Animals so she conjures flaming beasts for her attacks.
84	%%* PointlessBandAid: Shun
85	* PsychoticSmirk: [[spoiler:Kageyama]], and [[spoiler:Megumi, after her FaceHeelTurn]].
86	* PutOnABus: Misao's role in the game was replaced with Megumi in the anime (it should be noted that the characters do have different personalities). Both Misao and Jun also played a more important role in the game and were both main characters as opposed to their brief cameos in the anime.
87	* 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. Even in the sequel, set 31 years later, she reappears without showing any signs of aging.
88	* RedHerring: The old sweet potato vendor from one episode, who owns an exact duplicate of the Invaders' SinisterShades. It turns out that the real invader was [[spoiler:a cute white spitz that seemed irrelevant at the time. TheReveal was quite [[{{Narm}} narmy]], considering it showed the dog wearing sunglasses.]]
89	%%* TheRival: Jim Skylark, who is also TheAce
90	* RunningGag: The "Ooh, intense!" girl with her Marilyn Maneuver moments.
91	* SchoolSportUniform: Kaoru Konoe, the most athletic of the group, wears one 24/7, even when she's in civilain mode, to the point where the ''only'' episode of the anime where she isn't seen in one is the BeachEpisode. The anime also have more than one episode set during sports festivals, where all the girls wears burumas.
92	%%* SecretLegacy: Shun learns why his neglectful father was never home.
93	* {{Seers}}: Misao, in the anime, wields the Gate of Perception, giving her CombatClairvoyance to allow her teammates to anticipate enemy attacks. [[spoiler:Reiji's original Gate, the Gate of Foresight, permits him to see the future, but because nobody took him seriously when he predicted great tragedy for his family, his anger twisted it into his Inverse Gate.]]
94	* SexySecretary: Keiko, the second-in-command who's often seen serving The Commander, is quite the looker, and she also happens to be SchoolNurse.
95	* ShockAndAwe: Jun [[MeaningfulName Thunders]], a member of Jim's team.
96	* ShoutOut: [[spoiler: The spitz in episode 18's]] transformation sequence is similar to Series/{{Ultraman}}'s
97	** During the puppet show in episode 16, Reiko's witch character uses the "Isaki apam mehinam, eto caffe nam" invocation from Anime/MagicUsersClub -- which was also directed by Junichi Sato.
98	* SinisterShades: The Invaders wear these, as do the BigBad.
99	* SmallGirlBigGun: [[spoiler: The "Ooh! Intense!" girl turns out to be an undercover AEGIS agent who carries a {{BFG}}.]]
100	* SpiderSense: Misao Sakimori from Jim's team, who dictates the exact time before something happens, giving the group a serious tactical advantage. [[spoiler:Kageyama had the Gate of Foresight before his StartOfDarkness turned it into the Gate of Shadows. He got it back after he pulled a HeelFaceTurn.]]
101	* SpoilerOpening: The [[TheManBehindTheMan surprise]] BigBad gets revealed even before the first episode.
102	%%* StrangeSalute: The AEGIS Salute
103	* StrawNihilist: Shadow, he's in league with the bad guys because he's disgusted with humanity's evils.
104	%%* StudentCouncilPresident: Ruriko
105	* SuperCellReception: Many characters use specially designed cell phones to activate "Gates", the source of the series' [[FunctionalMagic magic-like abilities]].
106	* SuperPrototype: Gate Robot Unit 00, which has no PowerLimiter, unlike the later production models.
107	* SuperSpeed: Jim Skylark's Supersonic Gate lets his Gate Robot travel at astounding speed.
108	* SuperStrength: Kaoru, who additionally has SuperSpeed, as her Gate power amplifies her physical abilities. [[spoiler: Also, Bancho in the final epusode.]]
109	* {{Technopath}}: Kaiser Kikai has the ability to control machinery, and can manipulate things as big as battleships and trains.
110	* TieInNovel: ''Gatekeepers 1985'', which bridges the gap between ''Gate Keepers'' and ''Gate Keepers 21.''
111	* ThoseTwoGuys: Meguro "Megane" Kanetake and Banba "Banchou" Choutarou are side characters who support the team despite not having Gate powers of their own.
112	* ThoseWackyNazis: Kaiser Kikai has the look, and has a tendency to shout "HEIL VADER!" whenever he shows up.
113	* TimeStandsStill: The Commander's power. [[AllThereInTheManual Which is only depicted in the novel]].
114	* TragicMonster: Mr. Fukuoka, the teacher in Megumi's joining episode. He had a stronger sense of identity compared to most invaders and it was implied that his JerkAss behaviour throughout the episode was due to the Invaders messing with his head, giving him intense headaches and stressing him out. He still showed a soft spot for Megumi and was clearly torn between wanting to be human and fulfilling his mission as an Invader.
115	* TransformationTrinket: Infected people somehow get SinisterShades from nowhere, which they put on to transform into Invaders.
116	* UnstoppableRage: Gatekeepers who go into an UnstoppableRage gain "[[ReversePolarity Inverse Gates]]", which do the exact opposite of their original powers.
117	* TheVirus: The Invaders in ''Anime/GateKeepers21''.
118	* WaifFu: Kaoru Konoe and her tank-lifting introduction.
119	* TheWorfEffect: Kaiser Kikai easily defeats Jim's elite MultinationalTeam with his [[MilitaryMashupMachine tank on a battleship]], forcing AEGIS to deploy the SuperPrototype.
120	* TheWarRoom: Any AEGIS base. AEGIS Japan comes complete with BridgeBunnies.
