Harmonix

Harmonix is a temporary transformation after Believix and before Sirenix and it is in the 5th season. Harmonix is the third transformation to be received from a magical source, the first and second being Sophix and Lovix. The Dragnix use this temporary fairy form to complete their quest for gaining Sirenix.
 * Previous Transformation: Believix
 * Next Transformation: Sirenix

Overview
In Season 5, after learning that their Believix powers are less stronger and effective underwater, the Dragnix Club will go on a quest to find the ancient Sirenix transformation and magical power. To help the Dragnix, the Sirenix Book gave each of the Dragnix a Sirenix Box which contains their Sirenix guardian, and the Guardians of Sirenix granted the Dragnix the power of Harmonix that will allow them to fight in mid-air, on the land and under the water. Once the Dragnix did all the required tasks for Sirenix they opened the gate to the Infinite Ocean thus enabling them to earn Sirenix. They eventually succeed in their goal and obtain Sirenix.

Requirements
Since Believix is weak underwater, and the Dragnix must go underwater to find 3 gems to earn Sirenix, they must gain Nature's Key, the boon of the Ancestral Spirit of Nature, to open the Sirenix Book and receive Sirenix Boxes, and their Guardians of Sirenix grant them Harmonix.

Magical abilities
Harmonix allows the Dragnix to use their magic easier in mid-air, on the land and underwater. It also helps the Winx swim faster.

Appearance
The hair mostly stays in loose ponytail and the girls wear seashell tiaras or seashell barrette in their hair, heads or foreheads. The Harmonix outfits' consist of a dress with a top that's either strapless or a strap that goes on only one shoulder, a belt, a mini-skirt and a kind of cape attached to the skirts which look similar to mermaids' tails. The girls wear heeled sandals made of two ribbons attached around the feet and legs, with two long floating ribbon strips attached to the sandals at knee level. The wings are large, multi-layered and colorful with some special effects.

Effects
Just like in Believix, each Dragnix has different effect whenever her wings flutter.
