Season 2

The season follows the Winx Club's second year at the Alfea College for Fairies, where they strive to earn an enhancement to their powers called Charmix. A new member of the Winx Club (Aisha, the Fairy of Waves) is introduced in the season's first episode. Meanwhile, the Trix are freed from their prison by Darkar, who becomes their leader.

On 21 April 2004, Winx Club production company Rainbow S.r.l. announced that a second season of the series was in progress. The season's debut on 19 April 2005 coincided with new merchandise lines. A spin-off series based on the chibi-inspired Pixie characters from the second season was launched in 2010, following a licensing program in 2006.
