* AlternateCharacterInterpretation:
** Mana: Is she [[ThePollyanna an eternal optimist]], or just that good at [[StepfordSmiler stepfordism]]?
** Rikka: A PsychoLesbian, AmbiguouslyBi, or a lonely girl who is desperately searching for a partner in life because her parents almost ignore her?
* AuthorsSavingThrow: The premise of NonSerialMovie (Mana's getting married to a guy) was this as a response to Mana's LesYay tendencies being overblown by fans. [[SubvertedTrope But in the end, it didn't do much.]]
** After [[Anime/SmilePrettyCure the previous season]] consisted almost entirely of {{Filler}} episodes, ''Doki Doki'''s entire season is practically relevant to the plot.
* AwesomeMusic:
** The transformation theme for this season is downright EPIC.
** [[https://www.youtube.com/watch?v=7cRXnnNhlIk The song Makoto sings to Regina in Episode 40]] is very memorable.
* BaseBreaker:
** Regina, early on. Some of the fans thought she was completely unlikable and that Makoto was right to reject her, others that she was cute and just needed help and that Mana was right to befriend her. This tapered off late in the series as ''both'' sides embraced Regina as someone the plot screwed over.
** The Regina plot and the reveal of Cure Ace is either an ambitious subversion of the standard DarkMagicalGirl plot or a poorly written ShockingSwerve. [[TakeAThirdOption Or]] [[GoldenMeanFallacy both.]]
** Cure Ace herself. Is she a really badass and awesome new addition to the team or a badly shoehorned-in character who makes no sense? Is her being noticeably older than the Cures when transformed and noticeably younger when not appealing or off-putting? Is she a cool AloofAlly who just wants to help the girls to get stronger, [[FigureItOutYourself however indirectly]], or is she a smug and condescending girl who does nothing to help the Cures but takes the credit anyway? Fans seem to be rather split on this.
** People in the fandom either think Mana/Cure Heart is a MarySue who always gets away from actually learning anything because of her PlotArmor or think she's a great, strong protagonist whose flaws are still there even if she manages to push through them every time. There's a reason she gets "[[Wrestling/JohnCena Let's go Mana/Mana sucks!]]"
* BrokenBase:
** People are divided on the last episode. Specifically, whether you think it's a conclusive ending, or not conclusive at all. [[spoiler:Then there's the fact that Mana no-sells and solos the final boss, as up to that point, other Precure had always finished the BigBad off as a team.]]
** Is the NonSerialMovie canon, or not? While Cure Ace's inclusion is quite tacked on, and [[spoiler:the future everyone visited is lacking some individuals (mainly Joe and Regina)]], it's still possible for it to happen within the series' canon. WordOfGod even went on to clarify some contradictions, and revealed that there was supposed to be a {{Foreshadowing}} to the movie in one of earlier episodes. There are also several [[CanonImmigrant Canon Immigrants]] from the movie in the last three episodes.
** There is information that this series will be brought over as Seasons 3 and 4 of Creator/SabanBrands' ''Glitter Force'' dub series with even more episodes chopped out. Like with ''Anime/SmilePrettyCure'', people are divided over having this series finally brought to America and the fact that it's ''still'' being handled by Saban.
* CrossoverShip:
** Mana is shipped with previous season's [[Anime/SmilePrettyCure Miyuki]], thanks to the ''All-Stars New Stage 2'' movie. And as in ''All-Stars New Stage 3'', [[Anime/HappinessChargePrettyCure Megumi]] joins the fray.
** Makoto used to be shipped a lot with the other Cures, Marie-Ange, and even Davi [[spoiler:in her manager form]].
* ContestedSequel: ''Doki Doki!'' is the most polarizing season in the franchise thus far. Detractors are unhappy with this season due to perceived pacing problems as well as too much focus being given to Mana and Regina at the expense of the other characters, especially Rikka and Alice (albeit not quite to the extent the [[Anime/SuitePrettyCure previous]] [[Anime/SmilePrettyCure two seasons]]), while fans love the season for being DarkerAndEdgier and much more plot-heavy. [[BaseBreaker And then there's the reveal of Cure Ace]]...
* CounterpartComparison: To ''{{VideoGame/Aikatsu}}'', which is an idol anime and aired four months before the show. The two have many similarities, namely the shared card suit motif, and each has a red-ribbon blonde-haired girl. There have been crossover fanarts featuring the two shows, with Regina and Ichigo being the most prominent.

* DracoInLeatherPants:
** Regina quickly became this for the fanbase. [[spoiler:In hindsight, they were onto something with that.]]
** Ira, especially after episode 26 [[spoiler:when he suffered a bout of EasyAmnesia and TookALevelInKindness.]]
* DieForOurShip:
** Joe was already unpopular with certain fans due to being both [[MemeticMolester uncomfortably creepy around the teenage protagonists]] and [[HetIsEw a male who could be shipped with the girls]]. And then episode 17 revealed that [[spoiler:he was Princess Marie-Ange's fiance. This makes him a ''canon'' obstacle to a yuri pairing (Ange/Makoto) in a franchise where canon het couples are usually all-but-nonexistent, leaving the girls free to be shipped with each other.]] The fans who weren't fond of this reveal ''really'' weren't fond of this reveal.
** Regina is becoming this for certain Mana/Rikka shippers, some of whom have complained that the focus put on Regina and Mana's interactions necessitates Mana's devoted childhood friend Rikka, who was already getting shafted somewhat in favor of Makoto, getting pushed aside ''even more'' in order to give focus to Mana's growing relationship with Regina.
** And after Episode 26, [[spoiler:Ira]] is getting ''a lot'' of heat from Mana/Rikka shippers.
** [[spoiler:Nikaidou]] is the enemy, if not '''THE''' enemy for shippers of every LesYay couples that involves Mana. The hate began when one of movie promotional opening [[ShipTease shows him blushing when Mana gets too close on him]]. It got worse in the last two episodes, where [[spoiler:he starts using FirstNameBasis on Mana (which only her family, fellow Cures, and Regina do so) and spends most of his time talking about Mana]]. The real kicker? Most of his appearances in the series itself don't have anything to do with Mana.
* EarWorm: [[https://www.youtube.com/watch?v=fxfsmpwnXkM Beyond the Sky]].
* EnsembleDarkhorse:
** Makopi's manager, [[spoiler:actually Davi [[VoluntaryShapeshifting in human form]].]]
** Alice's butler, Sebastian, is also quite well-liked. [[spoiler:His stint as "Cure Batman" in episode 25 has definitely aided his popularity.]]
** Mana's homeroom teacher Kido is surprisingly popular within Precure's BaraGenre fandom.
* EvenBetterSequel: This season is considered to be much better then [[Anime/SuitePrettyCure the previous]] [[Anime/SmilePrettyCure two seasons]] by a number of fans.
* FanPreferredCouple:
** [[RedOniBlueOni Mana/]][[ChildhoodFriends Rikka]] was a popular ship among fans before the show even aired. When Mana and Rikka were shown to have a great deal of LesYay between them in canon (i.e. episode 2), the ship became even ''more'' popular, to the point of pretty much being this series' [[Anime/SuitePrettyCure Hibiki/Kanade]].
** Judging by the amount of fanworks alone, Ira/Rikka is now the most popular hetero couple of ''Doki Doki'', and one of the most popular of the franchise as a whole, only to be beaten by [[Anime/SmilePrettyCure previous season's]] [[InterspeciesRomance Wolfrun/Miyuki]]. To illustrate: in Pixiv, Ira/Rikka has '''''1000+''''' artworks. Other hetero couples of ''Doki Doki'' only reach '''one-tenth of it''' at most.
* FoeYay: Regina and Mana. Hammered home in episode 22, where they're shown sharing a bed in a rather romantic-looking manner.
* FoeYayShipping: Mana/Regina has become a popular choice. Ira/Rikka had become popular as well since episode 4, and became much more popular after episode 26.
* HilariousInHindsight:
** Creator/EiichiroOda considers the series as his rival to his ''Franchise/OnePiece''. Creator/MayumiTanaka plays both Luffy and Ira.
** Before ''Doki Doki'', there were pretty much flurries of fanmade Cure Hearts and Cure Diamonds among the fandom.
** Some fans have noticed that the spelling sequence of the Lovely Communes is just like the transformation scene for [[Series/KamenRiderWizard Kamen Rider Beast]]. Then he pretended to be an actual MagicalGirl in a later episode. [[http://safebooru.org/index.php?page=post&s=view&id=990034 Artists have noticed this]].
** There is an infamous ''Anime/HeartcatchPrettyCure'' doujin [[http://i.imgur.com/biWARhI.jpg out there]] that has the characters modeled after ''Manga/FistOfTheNorthStar''. Come this season, the title of Episode 23 has the words '''[[AnimeThemeSong Ai Wo Torimodose]]''' in it.
** Aguri's body is set on fire when she transforms into Cure Ace. [[Manga/OnePiece Portgas D. Ace]] had fire as his devil fruit powers. Cure Ace is voiced by Creator/RieKugimiya, who voiced [[LightNovel/ShakuganNoShana Shana]] with the blazing eyes and flaming red hair - Cure Ace has these, too. Ace's weapon - no, [[NamesTheSame not that]] [[Manga/OnePiece Ace]] - is called "Love Kiss Rouge". The first red Cure was [[Anime/YesPrettyCure5 Cure Rouge]], who had fire powers.
** Alice has been drawing comparisons with Batman. Then in episode 25, her butler Sebastian [[spoiler:makes a Batman-like Cure costume. And he was supposed to be the Alfred stand-in!]]
** The NonSerialMovie has "Mana's getting married" in its title. One year later, Mana's seiyuu Creator/HitomiNabatame [[http://www.animenewsnetwork.com/news/2014-08-04/dokidoki-precure-voice-actress-hitomi-nabatame-announces-marriage/.77272 gets married]].
* IronWoobie:
** Makopi, whose Woobie-quotience is enough to break the Woobie-o-meter several times. She's a refugee from a magical kingdom which was destroyed down to the spiritual level. She's a questing-knight in search of her lost queen, who might have been dead all along. She's a MagicalGirlWarrior fighting enemies made of the evil-defining aspect of humanity. And before she meet the other Cures, she's without allies except Davie.
** Anything that can be applied to Makopi can be applied to fellow Knight of Trump [[spoiler:Jonathan Klondike, known on Earth as Joe Okada]]. The poor man doesn't even have a fairy.
* ItsTheSameNowItSucks: The show received this even before it even ''aired'', due to unwarranted assumptions that it would be exactly like ''Anime/FreshPrettyCure''.
* JerkassWoobie: Regina, big-time.
* LauncherOfAThousandShips: Mana Aida is proving to be quite possibly the most shipped person in the series' history. Most of the girls that fans ship her with including Rikka, Alice, Makoto, Regina, and Aguri. And then there are jokes abound about how Dokidoki is a stealth HaremSeries. Pixiv even has a tag specified for ''her harem'' (マナハーレム). And ''then'' she still gets shipped with at least ''five'' guys.
* LesYay: So many examples that [[HoYay/DokiDokiPrecure it was given its own page]].
* MemeticBadass:
** Alice. Hell, there's even a tag on Pixiv called "Alice the War God". (武神ありす)
** Her Butler, Sebastian, is also considered an in-universe MemeticBadass. [[spoiler:He managed to create his own Cure lovead from scratch, too, if episode 25 is any indication.]]
** Mana Aida herself qualifies, especially since she threw a freaking Jikochuu train in one episode.
* MemeticMutation:
** "[[GratuitousEnglish My sweet heart]]", as said by Joe.
** Alice is already drawing comparisons to Franchise/{{Batman}}, what with being a rich "superhero" with a skilled butler.
** At one point, during the ending DancingTheme, the camera focuses on Cure Diamond during a rather... silly-looking part of the ending choreography. This led many Pretty Cure fans to believe that this meant Rikka was a bad dancer. Thus, the "[[http://www.tumblr.com/tagged/rikka+dancing Rikka dancing]]" meme was born.
** Speaking of Rikka, fanartists seem to like portraying her as a {{Yandere}} towards Mana, usually with Makoto (or more recently, Regina) involved. Interestingly, this is what they did to the [[Anime/SmilePrettyCure last season's]] Reika, who also had blue hair and had a very close Cure friend.
** [[TheHero Mana's]] [[EvilLaugh counter-evil]] [[http://www.youtube.com/watch?v=vYbSqvpbVlc laugh]].
** Makotonigiri.[[labelnote:explanation]]A scene in episode 22 depicts Makoto eating an onigiri with a somewhat funny expression. Japanese ImageBoards then began to edit this scene to ridiculous extent. Then the meme was brought to Global ImageBoards and the rest is history.[[/labelnote]]
* MemeticMolester: Quite a few fans find Joe to be quite creepy, given his flirtatious comments and how touchy-feely he tends to be.
* MoralEventHorizon: Regina's involvement in the destruction of Makopi's homeworld may not have been a MEH after all, but Bel is revealed in episode 46 to have unambiguously crossed the MEH when [[spoiler:he tried to corrupt Marie-Ange, which ultimately caused her to split in two and become Madoka Aguri and Regina]].
* {{Narm}}: When a Jikochuu is made from a VictimOfTheWeek, the way the heart bursts out of the person's chest resembles the visual effect when a cartoon character is madly in love with someone. Their appearances are, as a rule, more stupid/cute than actually remotely scary at all.
* NightmareFuel: The destruction of the Trump Kingdom and the fate of its citizens. The younger kids probably won't understand what it's like to lose your home and your folks, but it makes the older kids (and the older audience) cringe.
* OlderThanTheyThink: A MagicalGirl who harbors guilt over a past failure, and who is a foreigner on Earth who originally hails from the MagicWorld? [[Manga/WeddingPeach Now where have we heard that before?]]
* OneSceneWonder: Alice's grandfather Ichirou is voiced by {{Creator/Mugihito}}, yet he only appears in one scene of one episode.
* OT3: It is either Makoto/Mana/Rikka, Regina/Mana/Rikka, Regina/Mana/Makoto. Ira/Rikka/Raquel is slowly gaining popularity too.
* ReplacementScrappy: Aguri/Cure Ace was this for Regina fans. And there was a video of a girl crying when Ace is shown not to be Regina to fuel more hate. Thankfully, fans have mellowed down on her since she [[RescuedFromTheScrappyHeap reveals more about herself]].
* RescuedFromTheScrappyHeap: Aguri, post-CharacterDevelopment and after being revealed as a piece of Marie Ange.
* TheScrappy:
** Aguri/Cure Ace is immensely disliked, and is one of the reasons for for the show's low TV ratings, due to to how she was introduced, her bratty Drill Sargent Nature, and the fact that she ends up replacing Makoto as the expositor for most of the remaining MythArc. Made worse by the fact that she tried to kill an amnesiac and powerless Ira. Turns out it was a test, but fans still hate her for it. Explanation on how she's introduced: A new Cure is '''always''' a previously established character, and with that is sometimes either royality or a girl who made a HeelFaceTurn. Aguri is despised for breaking that tradition and [[ReplacementScrappy replacing a fan favorite]]. It looked like it was making Regina the new Cure. It is sadly thrown out when King Jikochu makes her evil again. Then Cure Ace shows up and easily deafeats Regina, who is PutOnABus for nearly the entire second half of Doki Doki. In the same episode it's quickly revealed that Ace is an Elementary School girl named Aguri, '''a new character who appears out of nowhere.''' Who then proceeds to do nothing but tell off the girls for several episodes.
** Thanks to episode 36, [[spoiler:Yashima]] gets a lot of hate for [[spoiler:introducing her boyfriend in front of Raquel (who gets a PrecociousCrush on her), ''all while thanking him''.]]
* ShipsThatPassInTheNight:
** [[FoeYay Marie-Ange/Marmo]] is this somewhat, probably because Marmo was the only Selfish member who personally confronted her.
** Rikka/Ira ''was'' this, with fans producing bucket-loads of fanart based solely off Marmo briefly teasing Ira about having a crush on Rikka in episode 4... and then [[ShipTease episode 26]] happened.
** From the HoYay side, [[TeacherStudentRomance Juujou/Kido]] is this, for not being shown interacting with each other.
* ShipToShipCombat: The [[DracoInLeatherPants Mana/Regina]] shippers vs. [[EnemyMine Mana/everyone else]] shippers.
* ShockingSwerve: [[spoiler: Regina turning evil ''again'' and Cure Ace being someone ''we've never met.'']]
* TheyWastedAPerfectlyGoodCharacter: While everyone aside from Mana, Regina and Cure Ace can be seen as this, Alice in particular gets the short end of the stick, as it can seem like her only purpose on the show is to use Rosetta Reflection.
* UncannyValley: Ai-chan just looks ''weird'', being more humanoid-looking than other ''Pretty Cure'' fairies.
* ViewerGenderConfusion: Between the {{Gender Blender Name}}s, typical cute mascot looks, and the fact that they're all voiced by women that don't even try to sound masculine, it's very easy to miss the fact that Raquel and Lance are male.
* VindicatedByHistory: Mana/Heart and Aguri/Ace were considered huge {{Base Breaker}}s during and after the show's run. However, they seem to get this as shown in [[https://www.reddit.com/r/precure/comments/42ktqv/cures_by_popularity_in_japanese/ in the 2015 Precure characters poll]]. Aguri was actually the ''top-ranking'' of the [=DokiDoki=] Cures, with Mana shortly following after her, and both rank in the top 10. This happens at least in the Japanese fandom as the two are still [[AmericansHateTingle extremely polarizing characters]] in the West.
* VisualEffectsOfAwesome: Aside from the series having relatively good animation throughout, Cure Ace's transformation takes this to a ridiculous level. It's almost near movie like when it comes to the animation quality and is considered to be the coolest looking transformation in the franchise to date. [[http://www.youtube.com/watch?v=jmkcQX0i2vE See it here in HD]].
