The Spirit of the forest is a thick woodland located in the World of Dreams. The forest has a fairy energy which manifests in the form of the Spirit. She is the fairy form of the entire forest.
Her voice sounds like many speaking slightly out of sync, as if it is coming from every tree in her forest.
She bears a strong resemblance to the Ethereal Fairies, particularly the green one. She is slender with light green skin, turquoise lips and light forest green hair which floats above her head. Her eyes are a pale yellow with no irises or pupils and she wears an emerald green mask attached to a crown decorated with leaves. A veil like the ones worn by the selkies is attached to the crown and she wears a lacy, light green dress and a collar resembling the leafy canopy of a tree. Her wings are large and sparkling with a light green aura.
Not much is known about her personality. After Tinkerbell attempted to corrupt her, she became suspicious and would trap anyone who entered her domain. She will help those who can prove to her they are against the queen.
At an unknown point in time, Tinkerbell attempted to corrupt her but failed.
World of Winx
In "The Fall of the Queen", the Crocodile Man lures the Winx (minus Bloom) into her forest. Not knowing who they were, she changed her forest into an inescapable maze. No matter what they tried, the fairies could not escape. The spirit then attacked them with her vines but Flora used her powers to speak with the spirit. She let her see deep into her heart. Seeing her sincerity and good heart, the spirit materialized in her fairy form and opened the passage to Tinkerbell's lair.
In "Neverland", the Spirit of the World of Dreams appears to the Winx after they gained Onyrix and tells them that they are the only ones capable of saving the World of Dreams. Aisha asks why, and she explains that their fairy magic is generated by dreams, so without dreams, fairies themselves would not exist. Stella insists that she would still exist without dreams, and the Spirit of the World of Dreams tells her that she would, but her magic would not. Tecna asks why she is telling them all of this now instead of the last time they were with her, and she says that now the Winx are ready to save the World of Dreams and all of the dreams in the world.
In "Tiger Lily", the Spirit of the World of Dreams asks Tiger Lily if she can see Matt. Tiger Lily confirms that she can, telling the spirit that he is in London receiving training. The spirit responds that the prophecy is about to come true, and when Tiger Lily says that the final clash has started, the Spirit of the World of Dreams tells her to let destiny unfold.
The Spirit of the Forest has the power over nature. She can control the entire forest and change its layout instantly. She can change the woods into constantly shifting, changing maze from which none can ever escape. She has absolute control of the forest and not even Flora can overcome her hold over the woodlands.
In Season 2, it is shown that the Winx's Onyrix powers were seemingly bestowed to them by the Spirit of the World of Dreams.
- She is likely inspired by dryads who, according to Greek mythology, are wood nymphs who are linked to their forests and if the forest died, they would die with it.
- Her appearance is similar to that of the Ethereal Fairies and of Daphne's nymph form.
