Season 5

The fifth season of Winx Club premiered on August 26, 2012, on Nickelodeon. The season consists of 26 episodes and concluded its run on September 22, 2013. Season 5 aired in Italy on Rai 2 from October 16, 2012 to April 24, 2013.

Production
The season officially began production after the international media company Viacom became a co-owner of Rainbow. Viacom launched and financed a revival of Winx Club, now produced between Viacom's Nickelodeon Animation Studio and Rainbow. Viacom called their revival an "all-new Winx Club" and a "fresh take on the [Winx] property," rather than a direct continuation of the previous seasons.

Before the official announcement, Iginio Straffi had previously mentioned that a fifth season of the show was planned. At the Licensing Expo 2010 and in a March 2010 interview with Straffi, it was detailed that the season would focus on the "further adventures of the seven magical fairies" as they gained a brand-new ability to choose between fairy forms. This plot was scrapped after the combined Rainbow/Viacom decided to retool the season into a full relaunch of the show.

As confirmed in 2010, Viacom's Nickelodeon Animation Studio co-developed the fifth season. Viacom assembled a team of long-time Nickelodeon writers for the season: Jeff Borkin, Carin Greenberg, Sarah Jenkins, Sascha Paladino, and Adam Peltzman. Janice Burgess, the key person of Nick Jr., served as creative consultant for the season, just as she did for the Specials. Nickelodeon's producers Sarah Kamen, Jonathan Foss, and Jeannine Hodson also returned from the specials. Peter Zizzo, a Grammy Award-winning songwriter for Nickelodeon, worked with Elisa Rosselli to compose many of the songs for this season.

Just like the following sixth and seventh seasons, Season 5 premiered on Nickelodeon internationally before airing in Italy. It premiered on August 26, 2012 on Nickelodeon USA. In Italy, it premiered on October 16, 2012.

Season 5 was named Winx Club: Beyond Believix on Nickelodeon (similarly to how Season 4 was named Winx Club: The Power of Believix and how Season 3 was named Winx Club: Enchantix).

After the thirteenth episode, the show went on a three-month hiatus with new episodes returning on February 17, 2013. A few months later, it went on hiatus yet again in May 2013 after the twenty-third episode with the remaining episodes airing in September 2013. The season concluded in Italy on April 24, 2013 and September 22, 2013 in the USA.

Synopsis

 * Along with "The Lilo", "A Magix Christmas" is also a stand-alone episode and is not counted in the continuity in USA, as the narrator introduced "Trix Tricks" as the episode after "The Gem of Empathy". Despite this, "A Magix Christmas" is still the tenth episode.
