Bloom, a girl living in Gardenia with her rabbit Kiko, discover to be a fairy. That’s why she enrolls at Alfea, the Magix college for fairies, where she meets new friends with which she forms the Winx Club. But she meets new enemies too: the Trix, three evil witches, want to steal the Dragon Flame, a power that Bloom holds inside herself. Thanks to that, Bloom will be able to defeat the Trix, bringing peace back to Magix.
The Trix are saved by Lord Darkar, who aims to use them in order to accomplish his plan: stealing Bloom to enter the Interplanetary Dimension, from which it is possible to conquer all the known worlds. To face this new menace, the Winx will be helped by a new fairy, Aisha, who will reveal them the Pixies’ secret and will lead them to Lord Darkar’s hideout to defeat him once and for all.
While the Winx get the Enchantix power, the whole Magic Dimension is about to be in danger: Valtor, an evil sorcerer, manages to escape from his magic jail and wants to steal all the Magical Essences from all the worlds, in order to become the most powerful sorcerer ever. It will be up to the Winx to save the worlds of Magic Dimension, by casting their new spells and overcoming terrible trials until the final fight against Valtor.
