The fifth season of Winx Club premiered on Nickelodeon, under the title Winx Club: Beyond Believix,[2] in the United States on 26 August 2012 and on Rai 2 in Italy on 16 October 2012. It is the first season produced with Nickelodeon.[3]
It is the first full season in the Winx Club revival series, following the 2011 specials that summarized seasons 1–2 of the original show.
In this season, the Winx face a threat underwater and will have to face a new dreadful villain, Tritannus. He was a normal triton who was mutated into a powerful demon mutant naga sea monster caused by pollution. His main goal is to become the emperor of the Infinite Ocean. He allies with the Trix and the leader, Icy, falls in love with him. The Believix power is not strong enough underwater, so the Winx start a challenging quest to get the ancient Sirenix power and become ocean fairies. It is also the first season to have the Winx return to being students at Alfea despite graduating in the first movie.
Rainbow's original description of the fifth season, given at the Licensing Show 2010 in Las Vegas, indicated that all seven Winx fairies would be active members in the season (Bloom, Flora, Roxy, Stella, Musa, Tecna and Aisha/Layla). Later in 2010, however, the season was heavily reworked. The new plan was for the season to be a "total brand relaunch" and focus much less on continuing previous stories. This was the first season to be produced with Nickelodeon, the first produced in HD and the first to use computer-animated graphics. Scenes using Harmonix were in 2D, while scenes set in world of the Infinite Ocean were rendered in CGI. "The Lilo" was broadcast as the season premiere in the United States, Romania, Australia, The Netherlands, Poland, Hungary, The Czech Republic, Germany and Canada. However, this was the fifth episode produced for the season. It premiered on 26 August 2012 on Nickelodeon in the United States, and on 16 October 2012 on Rai 2 in Italy, spanning 26 episodes. Like the sixth and seventh seasons, this season premiered on Nickelodeon networks worldwide ahead of the Italian broadcasts.
