Season 4

The season takes place a year after the events of the previous season and the feature film Winx Club: The Secret of the Lost Kingdom. The Winx Club fairies travel to Earth to protect its last terrestrial fairy from the four Wizards of the Black Circle. They also evolve their magic powers to Believix.

In 2011, the American company Viacom became a co-owner of the Rainbow studio, and Viacom's Nickelodeon began producing a Winx Club revival series. Before airing the Nick-produced episodes, Nickelodeon U.S. premiered the fourth season under the title Winx Club: The Power of Believix from 6 May 2012 to 29 July 2012.
