Winx Club (English, revival)

This is the third English dub of the series, originating in 2010, when Viacom acquired most of Rainbow, the company that produces the series, to mass relaunch the series to global audiences, primarily in American and English-speaking regions where the heavily edited 4Kids English dub was initially broadcasted and eventually cancelled.

Nickelodeon hired many famous actors to record their lines at Atlas Oceanic Sound and Picture, causing English-speaking fans to refer to episodes dubbed by this cast as the Nick dub of the series. Four TV specials that summarised the first two seasons, which were made primarily for Nick US, premiered on the network from June 27 - October 16, 2011. Later, the third and fourth seasons would be re-dubbed into English, using the Cinélume English dub as a base, broadcasting from late 2011-mid 2012. Brand new fifth and sixth seasons premiered from 2012-2015; from this point onwards, the series' animation, mainly the lip-syncing of characters, would be based off the English scripts instead of the original Italian version's.

Due to Rainbow going through financial struggles in 2014, the Hollywood voice actors by Atlas Oceanic were considered too costly to continue using; instead, DuArt Film and Video produced the English dub of season 7 with lesser known actors. For the seventh season, the show was moved to Nick Jr. and aired in 2016. In 2018, another studio, 3Beep, would then go on to produce the dub of season 8 with most of the same cast from DuArt, which was sporadically distributed. These dubbed episodes are known as the DuArt/3Beep dub by fans.

This is the longest running English dub of the series, and has, for the most part, dubbed the entire series.

History
After Viacom bought a portion of the company Rainbow, a relaunch of the Winx Club franchise began development in 2010, with Nickelodeon Animation Studio beginning co-production on a revived series, in which the Winx are once again students at Alfea, as they were before their graduation in the original show.

The revival was set to include four television specials that summarize the first two seasons of the original series and new seasons of the show, with Nickelodeon investing US$100 million into advertising the franchise. Notably, this English dub, due to Nickelodeon's heavy involvement, was produced by Hollywood recording studio Atlas Oceanic Sound and Picture, where, in a similar vain to theatrical animated movies, many famous actors were brought on board to participate, mainly major stars from the network at the time (Keke Palmer as Aisha, Elizabeth Gilles as Daphne, and Ariana Grande as Diaspro, for example), and well-known Hollywood voice actors (such as Dee Bradley Baker and Josh Keaton); Bloom was voiced by Molly C. Quinn, known for starring in ABC's Castle.

The TV specials premiered on Nickelodeon from June 27 - October 16, 2011. Later, the third and fourth seasons would be re-dubbed into English, using the Cinélume English dub as a base, broadcasting from late 2011-mid 2012; this re-dub slightly modified the original Cinélume scripts by changing awkward dialogue and errors, but there were also miscellaneous alterations at creator Iginio Straffi's request to make the series more suitable to younger audiences. The theme song for the re-dub of the original run was a new version of the season 4 theme song performed by Cymphonique Miller, with an accompanying music video. The first two movies would also be redubbed from the Dubbing Brothers versions.

From the fifth season onwards, the series' animation, mainly the lip-syncing of characters, would be based off the English scripts instead of the original Italian version's. Season 5 would finally premiere on August 26, 2012, with the fifth episode "The Lilo" as a sneak peek; this episode served to heavily promoted the Winx's Believix fairy form, accompanied by the English version of the song "We Are Believix" performed by Elizabeth Gilles, which also recieved a music video. The official first premiere was on September 2, 2012, before the official Italian premiere the following month, but it wouldn't conclude airing on the channel until September 22, 2013. Season 6 premiered a few days later on September 29, but most of the episodes premiered sporadically on the Nick website, causing them to premiere in other countries, particularly the UK, first, and would only be aired on TV by late 2015 on Nick Jr.

Rainbow was suffering financial struggles in 2014 during the production of season 7, due to the box office failure of their first major theatrical animated film, Gladiatori di Roma. One major cost cutting method used was no longer using the Hollywood voice actors by Atlas Oceanic, as they were considered to costly to continue using; instead, Nick Jr. commissioned the cheaper, New York-based studio DuArt Film and Video, to produce the English dub of season 7 with lesser known actors. Furthermore, due to the show's more noticeable switch to a more preschool orientated audience, the show was moved from the main Nickelodeon network to Nick Jr. in the United States, corresponding to the move from Rai 2 to Rai Gulp in Italy, although Nickelodeon internationally still aired the season. In the US, season seven aired in 2016, a year after the Italian premieres in 2015. Shortly after this, the Nickelodeon co-production with the franchise was quietly discontinued.

After DuArt worked alongside the studio 3Beep to produce the English dubbing of the spin-off World of Winx, 3Beep would then go on to produce the dub of the preschool-retooled season 8 in 2018, retaining most of DuArt's cast from season 7 and WOW. However, this season would not premiere in the US in 2019 like the Italian version, due to Nickelodeon having a much lesser role in the season's production and distribution. It would instead premiere sporadically on YouTube, Cartoon Network in Türkiye (through SAP) and Nickelodeon in Asia, before officially releasing in the country in February 2022 on Amazon Prime Video. The dub later also aired in Croatia on Mini TV from February 28 to March 8, 2023 with Croatian subtitles.

For simplicity, English-speaking fans of the series refer to the episodes dubbed by Atlas Oceanic as the Nick dub, and the episodes dubbed by DuArt and 3Beep collectively as the DuArt/3Beep dub, implying that both dubs are separate from one another when in fact they are merely one, as DuArt and 3Beep did not re-dub any episodes and continued off the Nick dub.

Errors

 * In the promo advertising season 3, Helena Evangeliou's and Jennifer Seguin's lines as Bloom and Stella respectively from the Cinélume dub are retained.
 * Throughout the dub of season 3, Lord Darkar is still referred to as Darkar. This causes an inconsistency, since in the TV specials, he's only referred to as "The Shadow Phoenix".
 * In episode 326, after Musa saves the fake Riven using her Fairy Dust, Anik Matern's performance from the Cinélume dub is retained.
 * Infamously, in episode 617, Bloom says "Magic Winx, Sirenix", even though she and the rest of the Winx transform into their Bloomix forms.
 * Although the error was later fixed to her saying "Magic Winx, Bloomix", countless international dubs that used this dub as a base also had the error and they left it unfixed.
