!!For the manga and anime series:

* AlternativeCharacterInterpretation: In the manga, did Zagato [[spoiler:actively kill Alcyone or simply stand by as she died of her wounds]]? Her cry for "mercy" could be interpreted either way.
* AwesomeMusic: All three opening and ending themes.
* BigLippedAlligatorMoment: The breast discussion in the second season is almost this, but for the {{Foreshadowing}} [[spoiler:about "Presea's" birthmark, a clue that she's not who she says she is]].
* CompleteMonster: Most characters get a sympathetic, or at least understandable, motive for what they do. The exception is the BigBad from the anime’s second season. [[EldritchAbomination Lady Debonair]], [[TheHeartless born from the collective fears]] of Cephiro's people, wants to [[OmnicidalManiac destroy the world]] for no understandable reason, cannot be reasoned with, and will use any despicable trick in the book to get her way. She abandons her own "daughter", Nova, to her fate after she fails in defeating the Magic Knights. She was the one who killed the very popular AntiVillain Eagle Vision for no reason at all and got [[{{Yandere}} the already unstable]] Alcyone completely BrainwashedAndCrazy so she could become her DarkActionGirl [[TheDragon Dragon]], killing her when the MindControl completely broke.
* DracoInLeatherPants: Zagato. Yes, his true motivation wasn't evil, but he still did plenty of evil things to try and achieve it and was incredibly callous to his own follower, Alcyone.
* {{Fanon}}:
** Fans and reviewers will often describe Fuu as shy or a wallflower, even though her very first action in the series is to walk up to a complete stranger and give her a gift. In fact, she shows no inclinations towards shyness or timidity through the entire series. Being thoughtful and an avid gamer does ''not'' overlap with shyness, people. Plus she's next to Hikaru and Umi for most of the story, and ''most'' people would look quiet and reserved next to those two.
** The assumption that Hikaru is poor because she doesn't go to a fancy private school like Umi and Fuu and her house is a kendo dojo. But it's definitely a BigFancyHouse anyway, just a more traditionally Japanese one--which means the Shidous are just as loaded as the Hououjis and Ryuuzakis.
** Some fans from Latin America think that the Pillar of Cephiro can [[AlwaysFemale only be a woman]], as Eagle is depicted as female in the Spanish dub.
* FanPreferredCouple: Although Umi/[[spoiler:Ascot]] is a kind of BetaCouple (though [[AllLoveIsUnrequited an unrequited one]]) in Part II, Umi/Clef is a very popular pairing in the fanbase because of the way their initial antagonism gives way to mutal respect and concern. Doesn't hurt that Umi admits having feelings for him in the anime.
* FridgeBrilliance: Eagle Vision has white hair, golden eyes, and a black outfit. The same coloring as a Bald Eagle. Which is the animal symbol of the United States of America- the country that Autozam represents. While the Middle East (represented by Chizeta) and China (represented by Fahren) are older cultural/geographical zones with many distinctive symbols, the USA is rather young and does not have those many distinctive elements. The Bald Eagle is one of the few easily recognizable ones.
* GermansLoveDavidHasselhoff: Or should we say, Latin Americans Love ''[[CompletelyDifferentTitle Guerreras Mágicas]]''. It's not without reason: it aired in between the 6th or 7th rerun of ''[[SaintSeiya Caballeros del Zodiaco]]'', ''DragonBall'' hadn't hit yet, ''Manga/RanmaOneHalf'' was silly, ''Anime/SlamDunk'' was on a chaotic rotation, ''Anime/{{Escaflowne}}'' took ages to get anywhere, and ''Anime/BtX'' also had a hectic airing. ''Rayearth'' was in comparison a well balanced, well written, [[MultipleDemographicAppeal both-genders-appealing]] soap opera with action and adventure. The tune was catchy too, and it was one of the first anime series to air with its intro mostly intact since since ''Anime/MazingerZ''.
* HoYay / FoeYay:
** Eagle and Lantis.
** Also, Eagle and Geo Metro. But Eagle ''is'' [[EvenTheGuysWantHim that pretty]].
** Averted in the Spanish dub, where Eagle is depicted as female. And hilariously, while they tried to avert HoYay... that dub actually ''created LesYay between girl!Eagle and Hikaru.''. [[DubText Oops]]?
** Presea's attention to Hikaru early on, and Hikaru's practically drooling over Fuu for at first. CLAMP is well known for this, though.
** Innouva is in love with Zagato, just like Alcyone - minus the AxCrazy, add IWantMyBelovedToBeHappy.
* JerkAssWoobie: [[spoiler: Alcyone, by the end of the second TV series. Specially with her AlasPoorVillain demise.]] Also [[spoiler: Nova, who is bon from Hikaru's own despair and sadness... but does really terrible things while trying to have her love.]]
* MoralEventHorizon:
** Alcyone was crazy and probably psychotic, and dragging herself on the ground because of the wounds Umi inflicted on her, [[spoiler: but did she really deserve to be abandoned by Zagato]]?
** Debonair [[spoiler: abandoning and then trying to kill the local JerkAssWoobie, Nova, who can be considered as her daughter. And then killing Eagle ''and'' Alcyone - and in the second case, when she was ''this'' close to a HeelFaceTurn.]]
* {{Narm}}:
** The way the beam of light shoots from Mokona's jewel to Umi's forehead when she learns her first magic spell looks a little odd.
** Lantis' introduction in the anime. He comes in carrying an unconscious woman. Everyone in the room completely fails to notice her, even when he puts her down on a couch and explains that she was hurt trying to get into the castle. Then they all freak out because he has a tiny bit of blood on his hand--even ''Fuu'' completely overlooks the '''unconscious''' person with unknown injuries in favor of something that looks little worse than a cat scratch.
* OneTrueThreesome:
** Given how close the girls are, how much they care about each other, and their frequent hand-holding, whenever LesYay shipping happens it often involves all three of them.
** Thanks to Hikaru's LoveYouAndEverybody and Eagle and Lantis' preinstalled HoYay, they're also a popular threesome.
* {{Padding}}: Because the manga's story moves very fast, the anime had to add new things to fill 20 episodes. Most of this is CharacterDevelopment and further exploration of Cephiro, which many consider to be beneficial since it allows viewers to see the world that the girls have to save. However, there is some blatant padding when the trio discusses topics that have already been covered and flash back to things that happened ''the last episode.''
* PeripheryDemographic: The SwordsAndSorcery and HumongousMecha elements have attracted a share of {{Shonen}} fans as well. (A few of them insist that it ''is'' shonen for GirlShowGhetto reasons, but they're incorrect. It's a shoujo story ''with'' giant robots.)
* TheScrappy: Primera the fairy isn´t very well liked by the fans, due her SmallNameBigEgo behavior and her [[DieForOurShip constant meddling between Hikaru and Lantis.]]
* ToyShip: Aska and Sanyun.
* WhatAnIdiot: In episode 12 of the anime, the girls are "attacked" repeatedly with unsteady ground, falling boulders and trees, etc. They quickly conclude that the dangers are illusory, which Hikaru proves by allowing a large tree to fall on her unscathed. When they duck into a cave for shelter, they see... Clef! Who was [[TakenForGranite petrified in the first episode]]! Now telling them that he rescued Emeraude himself and she's a-ok! This despite the fact that people have repeatedly told them they need to resurrect all three Mashin first and how the Magic Knights will be the ''only'' people able to save the princess, because all the Cephirans who have tried it failed miserably. And the girls... believe him with just the slightest hesitation. Fuu is the only one to suggest that his story is fishy. Cue shock from Hikaru and Umi when--''once again''--Clef and Emeraude turn out to be illusions and attack them.
* WhatDoYouMeanItsForKids: The original story is something like Emeraude calling three girls from another world to save Cephiro. Seems simple enough, right? Well, it's ''not.'' [[spoiler: The real reason the Knights were summoned was that only someone from another world can ''kill the Pillar.'' And they have to go through with it. It ''really '' [[BreakTheCutie tears Hikaru up]], and in the anime it [[LiteralSplitPersonality splits her into two parts]], [[TheEeyore a girl about to cry]] and [[TheVamp her evil half]].]] Despite this, the manga belongs to the ShoujoDemographic.
* TheWoobie:
** The three Magic Knights [[spoiler:after killing Emeraude]].
** Also [[spoiler: Sierra]]. Say what you will in regards to [[spoiler: the plot holes surrounding her appearance]], but [[spoiler: her inadequacies in regards to her dead yet still beloved older sister as well as her feelings for Clef]] are ''very'' powerful Woobie material.
