- The Abridged Series: Has one by the name of Heartcatch Pretty Cure! A Bridging.
- Anime First
- Cowboy BeBop at His Computer: The book Drawing Fantastic Female Fighters, which features character sheets and concept art from this series and Fresh Pretty Cure!, 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 All-Stars DX 2, which isn't even the franchise's first crossover movie. The book might have been confusing the show for Hugtto! Pretty Cure, which was released around the time the book was published and had cameos from Cure Black and Cure White in its 22nd episode and basically every single Pretty Cure to date in episodes 36 and 37.
- Fan Nickname:
- "Zetsubou Sensei Kamen" or "Tuxedo Megane" for Tsubomi's Mysterious Protector before he was revealed to be Tsubomi's grandpa and eventually Coupe, due to his resemblance to a certain suicidal teacher and/or a certain other mysterious protector.
- There's also Cure Mercury and Fate Hanasaki for Yuri and Tsubomi, due to their voice actresses.
- He Also Did: Besides her famous role as the voice of Cure Marine, Fumie Mizusawa is also a published novelist who wrote Kagurazaka G7: Gakeppuchi Cafe Kyuushutsu Sakusen Kaigi.
- Name's the Same:
- The Dune in this series shouldn't be confused with the Dune in Casshern Sins, even though the same team was involved with both series.
- The Cure Ange in The Movie shouldn't be confused with the eventual Hugtto! Pretty Cure Cure Ange. Though it helps that both are pronounced differently (HC Ange is pronounced "Anje", while HUG Ange is pronounced "Angu").
- Newbie Boom: 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 Pretty Cure fandom to suddenly become huge during this series.
- Part of it could be due to a well-liked blogger posting individual episode reviews during its run, praising it up the wazoo every week, probably prompting people to check it out.
- Playing Against Type:
- Akira Ishida usually plays effeminate males. Cologne certainly doesn't look the part.
- Nana Mizuki playing a normal Magical Girl who also happens to be, at first, the weakest instead of a Dark Magical Girl as well as her Shadow Archetype Cure Blossom Mirage.
- Minami Takayama doesn't do crazy psychopaths often, but Dark Precure isn't the only artificially made psychopath she played.
- Portmanteau Series Nickname:
- 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."
- Promoted Fangirl: Nana Mizuki loves the Pretty Cure series and was ecstatic when she's landed the role of Tsubomi.
- Relationship Voice Actor: Surprisingly all of the Heartcatch Precures are from Lyrical Nanoha (Fate, Lindy) and Fate/stay night (Mordred (DEEN version), Ayako). The Nanoha alumnus eventually became involved with the Fate Series come Fate/Grand Order (Nagao Kagetora and Demeter).
- Also, Yuri and Dark Precure are Palutena and Pit.
