In the comic and book series, the Winx have attained seven levels of power exclusive to the series.
- Main article: Winx (Form)
Winx is the standard transformation for Alfea fairies. Fairies can more easily manifest their magic than when they are in civilian form as well as use more powerful spells. A fairy is usually able to transform when she has a strong enough will and fully believes in her magical capabilities.
- Main article: Charmix (Form)
Charmix boosts the magical energy of a fairy, making her more powerful and allowing her to use magic in more diverse environments. In order to earn Charmix, a fairy must overcome a great personal difficulty. It can run out of energy and drain its user's magical energy.
- Main article: Enchantix (Form)
Enchantix is the "Final Fairy Form" in a fairy's journey to become a full-fledged fairy. It allows them to miniaturize themselves and to use Fairy Dust to break dark spells. Enchantix fairies are the Guardian Fairies of the Magic Dimension. In order for a fairy to earn her Enchantix, she has to save someone from her home planet and show great sacrifice in doing so. However, Enchantix gained unconventionally is incomplete and the fairy cannot use her miniaturization powers and can easily lose control.
Higher Fairy Levels
After Enchantix, there is an infinite number of levels a fairy can reach. Higher Fairy Levels are meant for specific situations.
- Main article: Believix (Form)
Believix gives its users the ability to make people open their hearts to good feelings and to make them believe in magic. There are three additional sets of wings, the Speedix wings, which allow fairies to fly extremely fast; the Tracix wings, which allow fairies to magically connect to places and see the history of these places; and the Zoomix wings, which allow fairies to teleport themselves. In order for a fairy to earn Believix, she must make people believe in fairies and magic.
There are levels of power acquired via power sources or magical items.
Gifts of Destiny

Sophix is the Gift of Wisdom and allows fairies to connect themselves with the powers of nature.
- Main article: Lovix
Lovix is the Gift of Heart and allows the user enough courage to face a great danger and to protect themselves from the cold.
- Main article: Harmonix (Form)
Harmonix allows fairies to use their magic easier in midair, on land, and underwater. It also helps fairies to swim faster. In order for a fairy to earn Harmonix, they must locate and open the Sirenix Book. Their Guardians of Sirenix will then grant them Harmonix.
- Main article: Sirenix (Form)
Sirenix grants its possessor access to the Infinite Ocean and gives fairies the ability to use their magic easier in midair, on land, and underwater. It also helps them to swim faster. 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 Source of Sirenix in Lake Roccaluce.
- Main article: Bloomix (Form)
Bloomix is born of the magic of the Dragon Flame. Bloomix gives the Winx their magic back after the Legendarium stripped them of their powers. In order to earn Bloomix, a fairy must have a part of the Dragon Flame. She must then perform a good and courageous act worthy of a fairy.
- Main article: Mythix
Mythix gives its users the ability to enter the Legendarium World, and also the ability to teleport themselves in and out of the Legendarium World. The Ancestral Wands grant their users the ability to summon projections of legendary clues by exclaiming "Mythix vision" or "Mythix insight". The wands are also used as a homing device for the Fantasy Emerald and the Silver Spear. In order to earn Mythix, a fairy must prove herself before the Ancestral Wands. In turn, the wand she receives will grant her Mythix.
- Main article: Butterflix
As the essence of the nature, Butterflix grants its users nature-based power. However, it cannot damage nature itself. In order to earn Butterflix, a fairy must prove themselves worthy as the true defender of the Fairy Animals.
- Main article: Tynix (Form)
Tynix grants fairies the ability to enter the MiniWorlds, as well as teleport themselves from the MiniWorlds to the normal world. Via the Tynix Bracelets, fairies can also communicate with Fairy Animals. The Tynix power also creates an unbreakable bond between fairies and their bonded Fairy Animals, making it so that no matter how distant a fairy and her bonded Fairy Animal are, they can join together. In order to earn Tynix, a fairy must be granted a Tynix Bracelet by their bonded Fairy Animal.
World of Winx
- Main article: Dreamix (Form)
The source of Dreamix power is dreams and talents. The way of earning Dreamix is only vaguely mentioned in the show. It seems as though the Winx earned Dreamix during Annabelle's performance, as they experience a vision of the transformation sequence at the same time Annabelle's dream comes true (which never would have happened without their help).
- Main article: Onyrix (Form)
With Onyrix, fairies are granted the ability to enter the World of Dreams without the use of the Magic Watch from the previous season. In order for a fairy to earn Onyrix, she must earn Dreamix first. Then the Spirit of the World of Dreams grants her Onyrix.
