Sirenix (Form)

Sirenix is the second Fairy Form introduced in Season 5. It is parallel to Harmonix. The Sirenix is the oldest power in the Magic Dimension. It is also the greatest power in all the oceans.

Overview
In Season 5, the Winx meet with Faragonda to discuss their newfound knowledge of their Believix powers being less effective underwater, and they learn that they must acquire Sirenix in order to defeat Tritannus. Faragonda tells them that Sirenix is an ancient power that was born of the magic of the oceans, and that no one has acquired Sirenix for a long time.

She informs that that in order to begin their quest, they must find the Sirenix Book, but the only person who knows its location is Daphne, Bloom's sister and the last fairy to acquire Sirenix. When Bloom asks Daphne about the location of the Sirenix Book, Daphne tells her not to look for it because it is dangerous. When the Ancestral Witches attacked Domino, she acquired Sirenix and was ready to use it against them but the Ancesral Witches had placed a spell on Sirenix and when Daphne tried to use it, it turned against her and caused her to become a spirit without a body. Bloom ends up persuading Daphne, who reveals that the Sirenix Book is in the Magic Archive of Alfea.

The Source of Sirenix is found in the cave where Daphne dwells in Lake Roccaluce which protects Sirenix and grants it to fairies who have completed the Sirenix Quest. Due to the curse, if a fairy does not complete the Sirenix Quest within one lunar cycle, they will lose their powers forever.

In Season 8, it is revealed that due to the magical ice on Dyamond, Sirenix can adapt to the area's weather, changing its form into Crystal Sirenix. According to Tecna, it has a high degree of adaptability.

Sirenix
In order for a fairy to earn Sirenix, they must find the Gem of Self-Confidence, the Gem of Empathy, and the Gem of Courage. After that, they need to activate the magic spring of Lake Roccaluce by using the Source of Sirenix.

Dark Sirenix
It is unknown if a witch can earn Sirenix by completing Sirenix Quest or not as it is a fairy power. In the Trix's case, after Tritannus forced Daphne to tell him where the source of Sirenix power was, Tritannus headed to Lake Roccaluce to destroy the Source of Sirenix, so her Sirenix cannot be protected from being stolen by him. After he destroyed the source, Tritannus absorbed Daphne's Sirenix powers and used his trident to grant the Trix Sirenix powers, which were mixed with his pollution powers.

Sirenix Clues
The Sirenix Clues were riddles given to the Winx to find the gems of Self-Confidence, Empathy, and Courage.


 * Andros:"With every twist and turn, the deeper you go until the Shimmering Shells sing with the ocean's voice."


 * Solaria:"Venture where the dark depth of the ocean shine. A precious gem, self-confidence, lies in the deeps."


 * Melody:"Like a ruby shining under the sea, corals are strings that you feel in a key."

"The Winx had to understand the message in the Ruby Reef's music. It leads them to Data Bridge Castle in which Aisha, Bloom and Tecna have unity."
 * Zenith:"To find the gem, you must understand the message in the harp's music."


 * Linphea:"Find the Flowers of the Depths. It answers only to courage."


 * Domino:"Find the Yellow Reef and snatch courage from its jaws."

Magical Abilities
Sirenix grants its possessor access to the Infinite Ocean and gives fairies and witches the ability to use their magic easier in midair, on land, and underwater. It also helps them to swim faster and freely breathe underwater.

In Season 8, it is revealed that their Crystal Sirenix power grants them another ability, the Crystal Sirenix light, which allows them to see the darkest part of the ocean. Their Crystal Sirenix power also protects from the cold.

Special Sirenix Powers
With Sirenix, a fairy has a power that can be used in specific situations. Every fairy has a different type of this power:

Daphne and Politea's Special Sirenix Powers are both unknown.

Effects
Every girl has a water bubble special effect when their wings flutter.

Sirenix Wish
Once gaining Sirenix, a fairy is given a wish which they can ask their Guardian of Sirenix to grant once they have pleased destiny.
 * Bloom wished for the Sirenix Curse to be broken forever. (S5E26)
 * Stella wished that her parents would listen to their hearts more. (S5E23)
 * Flora wished for all people on Earth to respect nature. (S5E24)
 * Tecna wished for all people of Zenith to be more connected to the Magic Dimension. (S5E22)
 * Aisha wished for Nereus to come back to life. (S5E25)

Musa has never used her wish. It is also unclear if she has pleased destiny. Daphne and Politea are also unknown whether they had used their respective wishes or not.

Sirenix Curse
Sirenix was cursed by the Ancestral Witches, turning Daphne into a disembodied spirit and Politea into a ravenous monster. The curse also caused the Sirenix power to turn against Daphne when she tried using it to defend herself from the Ancestral Witches, and caused Politea's own enormous Sirenix powers to be corrupted. The Sirenix Curse could punish the possessor physically, as revealed when Tritannus was attacked by the Emperor's Throne and Daphne revealed that it is the effect of the Sirenix Curse. The Sirenix Curse also caused the ocean level of the Infinite Ocean to drop. Later, by using her Sirenix wish, Bloom breaks the curse put on Sirenix.
