* TheAbridgedSeries: [[https://www.youtube.com/playlist?list=PL1I099-tUurfiwooMRXJKH2erdss2Y83A Has one]] by the name of ''WebVideo/HeartcatchPrettyCureABridging''.
* AnimeFirst: Like all ''[=PreCure=]'' series, the anime started first in February 2010, while the manga didn't release until a month later.
* CowboyBebopAtHisComputer: The book ''Drawing Fantastic Female Fighters'', which features character sheets and concept art from this series and ''Anime/FreshPrettyCure'', states that ''Heartcatch'' is the first season to feature returning characters from previous seasons. The problem? That ''never'' happens in the show itself, only in ''[[Anime/PrettyCureAllStars All-Stars DX 2,]]'' which isn't even the franchise's first crossover movie. The book might have been confusing the show for ''Anime/HugttoPrettyCure'', which was released around the time the book was published and had [[spoiler: cameos from [[Anime/FutariWaPrettyCure Cure Black and Cure White]]]] in its 22nd episode and [[spoiler: basically every single Pretty Cure to date]] in episodes 36 and 37.
* HeAlsoDid: Besides her famous role as the voice of Cure Marine, Creator/FumieMizusawa is also a published novelist who wrote ''Kagurazaka G7: Gakeppuchi Cafe Kyuushutsu Sakusen Kaigi''.
* MarthDebutedInSmashBros: The girls' first appearance in North American shores? ''Anime/TropicalRougePrettyCure'' episode 33, which has the team in a cameo appearance.
* NewbieBoom: Maybe it was some aspect of the series itself, or maybe it was because it happened to grab the attention of a prominent fansub group, but ''something'' caused the English-speaking ''Anime/PrettyCure'' fandom to suddenly become huge during this series.
** Part of it could be due to a [[https://starcrossedanime.com/category/finished-series-storybook/heartcatch/ well-liked blogger posting individual episode reviews]] during its run, praising it up the wazoo every week, probably prompting people to check it out.
* PlayingAgainstType:
** Creator/AkiraIshida usually plays effeminate males. Cologne certainly doesn't look the part.
** Creator/NanaMizuki playing a normal MagicalGirl who also happens to be, at first, the weakest instead of a DarkMagicalGirl [[spoiler: as well as her ShadowArchetype Cure Blossom Mirage]].
** Creator/MinamiTakayama doesn't do crazy psychopaths often, but Dark Precure isn't the only [[Anime/TheVisionOfEscaflowne artificially made psychopath she played]].
* PortmanteauSeriesNickname:
** ''Precure'' being a portmanteau of ''Pretty Cure'', like always. And a perfectly canon portmanteau at that, considering it's right there in the logo.
** Also, amongst the Japanese fans at least, this particular series is known as "Haatopuri," or "[=HeartPre=]."
* [[PromotedFanboy Promoted Fangirl]]: Creator/NanaMizuki ''loves'' the Pretty Cure series and was ecstatic when she's landed the role of Tsubomi.
* ReferencedBy:
** ''Manga/AhoGirl'': Yoshiko gets tickets for a ''[[BlandNameProduct PreChure]]'' movie, in which the protagonists resemble Blossom and Marine.
** ''Manga/ShinozakisanKiWoOtaShikaNi'': Kaede enjoys an anime titled ''[=HeartBreak=] [=PrePure=]''.
** ''Webcomic/SleeplessDomain'': Yuri Tsukikage's grave can be spotted among the MagicalGirl graveyard.
* WhatCouldHaveBeen: Originally, Nana Mizuki auditioned to play Erika while Fumie Mizusawa auditioned to play Tsubomi, only to switch roles once Toei realized how well they fit their opposites.
