* DevelopmentHell: While the series itself didn't suffer this, FanSub efforts are another matter entirely: ''[=YPC5=]'' seems to somehow repel attempts at translation. The first season, which ran from February 2007 to January 2008, was finally fully translated in ''October 2012'', and even then only as a hodgepodge of several distinct translation efforts. The second season, which ran from February 2008 to January 2009, remained unfinished until ''December 2013'', as the only fansub group wiling to sub it were also busy with the other ''Precure'' series and ''Anime/OjamajoDoremi''. The slow pace of subbing prompted another group to start subbing the series ''backwards'' from the end so that the whole series could be subbed faster.

** Urara: Cream Horn (for Cure Lemonade's hair), Cure Pine-Sol, Urarararara.

* FranchiseKiller: Believe it or not, ''[=GoGo=]'', with it's poor ratings and merchandise sales, nearly killed the Pretty Cure franchise. Had the season following it, ''Anime/FreshPrettyCure'', failed financially, it would of been the last series after this one because of how badly it did.
* PortmanteauSeriesNickname: Though it was common before, this series, particularly with its caption-less logo, made it look quite likely that both "Pretty Cure" and "Precure" are canon, both for the name of the series and for the name of the group. Later seasons of ''Pretty Cure'' actually use "Precure" in the English caption.
