“Winx Club is all about girl power,” said Brown Johnson, President, Animation, Nickelodeon and MTVN Kids and Family Group. “It focuses on a group of super-fashionable fairies whose friendship and teamwork empower them to face any challenge thrown their way – from scary monsters to evil witches.”
Winx Club is an animated modern fantasy adventure series that follows six best friends — Bloom, Stella, Flora, Musa, Tecna and Aisha — enrolled in Alfea College, the finest fairy school in all the realms. When trouble arises, the Winx transform into beautiful fairies who use their unique magical powers to fight villains and save the world from evil. Winx Club first debuted in Italy six years ago and quickly became a hit that has generated an international franchise of toys, books, clothing, and DVDs, as well as a CG-animated feature film.
Bloom (Quinn) is the most powerful fairy and leader of the Winx. She has an inborn ability to sense danger, combined with a lively intelligence and a deep sense of loyalty. As the fairy of the waves, Aisha (Palmer) is fearless, determined, energetic, and a sports enthusiast. Skye (Shively) is the leader of the Specialists, a group of teenage boys from a neighboring school who befriend the Winx fairies and fight alongside them to battle evil. The fairy sister of Bloom, Daphne (Gillies), sacrifices her life in order to keep Bloom safe and sometimes appears to her sister as an advisor. And, Diaspro (Grande), a somewhat materialistic princess who can be difficult at times.
