Pretty Cure is a franchise that lends itself well to fanseasons, particularly after 2008, creating a tight-knit community within an already small-town-like fandom. Much like the rest of the English fandom, the OC fic writers congregate at LiveJournal.
Creative Activities Precure, featuring a Creative Activities thematic like its title. It has a group of three girls who use the power of their clubs to transform with probably(not likely, but probably) the two oddest mascots in Fancure History.
Pretty Cure Candy Sweet, featuring a Candy, Sweets and Form Changing thematic. Another group of three who can change into different sweet/candy themed forms. These girls go to a baking school too.
Pretty Cure Luminous Spark, featuring a Special Effects and Light thematic. His first group of four who have a iPad mini for a mascot.
Sailor Suit Pretty Cure, featuring a Fashion and Sailor Uniform thematic. Another group of three and a corset and lipstick as a mascot.
