Season 4
She was summoned by Faragonda through a charm and asked to assist the Winx in their mission as they go up against the Major Fairies. Of the three Ethereal Fairies, she is the first to present the Winx their first Gifts of Destiny: Sophix. After the Orange Ethereal Fairy finishes her explanation of the gift to the Winx and Nabu, the Blue Ethereal Fairy imbues the girls with their gifts. She then leaves with her group and returns after the Winx dealt with Diana, the Major Fairy of Nature. She praises their work in using the gift wisely and thus, relieved Diana of her thirst for vengeance. When the Winx ask what they will need to do with their second gift, the Fairy simply answers that it is needed on their next mission then teleports away.

The Fairy still wanted to make sure the Winx were worthy of these gifts and observed them as they carried out their mission. She concludes that they are indeed worthy when they set aside their negative feelings for the Wizards and granted them protection from the Vengeance Fairies per their request. Once the Wizards are safely escorted to Sibylla, she appears alongside her fellow Ethereal Fairies to give their approval and also to mention that their second gift, Lovix will be there to help them make a difficult decision and great danger.

She appears one last time when the Winx had won an agreement with the Vengeance Fairies and Queen Morgana: the Earth Fairies must permitted the Wizards of the Black Circle to face a fair and impartial court for their crimes. She appears in the interdimensional portal the Winx were in as they were traveling home but the mood is more solemn this time. The Orange Ethereal Fairy presents them with the final gift: the Black Gift and explains that it is a powerful and dangerous spell that can bring someone back to life. The Green Ethereal Fairy further clarifies that someone will be in between the life and death threshold. That is all there is to say and the Blue Ethereal Fairy merely states that this is the prophecy and leaves, leaving the Winx confused.

Magical Abilities
The Ethereal Fairies are powerful magical creatures. They are timeless and immortal, existing outside of time. Nabu has stated their magic is archaic and very sweet. They can travel from interdimensinally as seen when they appeared to the Winx when they were traveling through an interdimensional portal from Aurora's Frost Tower to their lounge at Love & Pet. The Ethereal Fairies are the guardians of the Gifts of Destiny. They also know what will happen in the future and can warn the beings they are supposed to help. The Ethereal Fairies were destined to help the Winx defend the Earth from the Wizards of the Black Circle and from the vengeance of the Earth Fairies.
