- Box Office Bomb: The Movie, in comparison to the previous season's movie. It's actually a good movie, according to reports, that simply had the bad luck to be released in the middle of Typhoon Vongfong, and considering Vongfong was one hell (for want of a better term) of a typhoon, falling behind Doki Doki in its opening weekend was pretty much expected. It did better in its second weekend but still got curb-stomped by Kin Kyori Rennai.
- Sleeper Hit: On the other hand, the second weekend had it gross enough to be the fourth highest grossing non-Pretty Cure All Stars movie and the second highest grossing Non-Serial Movie after Doki Doki's movie, regardless. It even beat sibling movie Zyuden Sentai Kyoryuger Vs Gobusters, the Live-Action Adaptation of Kiki's Delivery Service, and The LEGO Movie.
- The Cast Showoff: Megumi Nakajima is well-known as a Idol Singer, providing the voicebank for the Vocaloid GUMI and for her breakout role as Ranka Lee in Macross Frontier. Subsequently, there are a lot of scenes where her character is singing to herself.
- Creator Killer: This season, the second in the one-two punch that started with Doki Doki, is said to have sealed the fate of series producer Hiroaki Shibata, who was moved to Toei's Super Sentai department before successor Go! Princess Pretty Cure was even halfway through.
- The Danza: Megumi Nakajima as Megumi Aino.
- Defictionalization: Yuuko's rice snacks.
- Fan Nickname: The season's been called "HaChaPre" by a good chunk of the fandom.
- Fan artists on Pixiv have given Megumi a nickname that translates to "Cure Roughly", stemming from the surprising viciousness of some of her attacks.
- The American Precure team, Bomburger Precure/Bombergirl Precure, has some fan nicknames: the redhead on this team is called Cure Sheriff and the blonde Cure Deputy (a name for the Native American girl has yet to catch on).
- "Cure Lovely Ballerina Form" for Super Happiness Lovely, due to the costume resembling that of a ballerina.
- Franchise Killer: As mentioned above, HaCha resulted in a massive shakeup in the Pretty Cure department at Toei. Interestingly, it was supposed to be a major improvement over DokiDoki.
- Meaningful Release Date: Episode 15, a Mother's Day episode released on Mother's Day, 2014.
- Related to this trope, Episode 19 was a soccer themed episode. It aired on the same week as the start of the 2014 World Cup.
- Memetic Mutation: There's a scene in episode 24 in which the Pretty Cure train at the beach. When Ribbon asks why they are taking a photo by a water fountain, Glasses says "The Super Sentai always pose at this place". A meme on tumblr usually puts an image of a shocked animal or human after it.
- Cure Peace's congratulatory message was still being talked about for months after it aired, and is still remembered to this day.
- Milestone Celebration: While Doki Doki Pretty Cure was the tenth Pretty Cure series released, Toei is considering Happiness Charge to be the 10th Anniversary series.
- To go along with this, the first 33 episodes will have special celebratory segments, one each for the heroines of the previous seasons.
- To celebrate the franchise's 500th episode, episode 14 has a special opening segment with the four Happiness Charge heroines.
- Promoted Fanboy: Like Nana Mizuki and Hitomi Nabatame before her, Megumi Nakajima says she's been a Pretty Cure fan for some time, and she's happy she gets to star in a show of her own.
- Relationship Voice Actor:
- Retroactive Recognition: Rina Kitagawa, the voice actress of Yuko Oomori/Cure Honey, would later go on to voice Lunafreya Nox Fleuret.
