Harmonix is the winx's transformation after their Believix, they earn this after coming in harmony and
believing in magic, this takes them to "beyond believix" as you can see that's why there is a new season named
after that on Nick,because they went beyond believing, now into a harmonious transformation!
In this season the Winx will obtain two new transformations: Harmonix and Sirenix.
