Fairies’ abilities are limited in their civilian forms. To increase their magical abilities, they transform into fairies and are able to use their powers with greater ease, gain wings, and new clothes and accessories. There are standard fairy levels, which are gained during a fairy's formal education journey to become a full-fledged fairy, and an infinite number of higher fairy levels and acquired powers meant for specific situations.
In the comic and book series, the Winx have attained eight levels of power exclusive to the series.
Standard Fairy Levels
These levels of power are gained during a fairy's formal education journey to become a full-fledged fairy.
- Main article: Winx (Form)
In Season 1, Stella introduces Winx when fighting Knut in Gardenia Park. Winx is the standard Fairy Form for Alfea fairies. A fairy is usually able to transform when she has a strong enough will and fully believes in her magical capabilities. Fairies can more easily manifest their magic than when they are in civilian form as well as use more powerful spells.
- Main article: Charmix (Form)
In Season 2, Chatta introduces to the Winx the concept of Charmix after Bloom earns hers. In Alfea's curriculum, earning Charmix is the goal of a second-year fairy. In order to earn Charmix, a fairy must overcome a great personal difficulty. Charmix boosts the magical energy of a fairy, making her more powerful and allowing her to use magic in more diverse environments. It can run out of energy and drain its user’s magical energy.
- Main article: Enchantix (Form)
In Season 3, Faragonda introduces Enchantix to the Alfea fairies upon their return from spring break. Enchantix is the "Final Fairy Form" in a fairy's formal educational journey to become a full-fledged fairy. In Alfea's curriculum, earning Enchantix is considered their final exam. Enchantix fairies who graduate from Alfea are also the Guardian Fairies of their respective homeworlds, bound to protect their worlds from evil and destruction. In order for a fairy to earn Enchantix, she must rescue someone from her homeworld and show great sacrifice in doing so.
Along with an increase in magical strength and endurance, Enchantix allows fairies to use Fairy Dust to miniaturize, break dark spells, and various other things. Enchantix wings are sustainable at higher wind speeds than those of a standard fairy. Enchantix also allows fairies to earn Higher Fairy Forms such as Believix.
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)
In Season 4, Faragonda brings the Winx into the Hall of Enchantments and informs them that after Enchantix, there is an infinite number of levels a fairy can reach, the one above Enchantix being Believix, a Fairy Form that can affect the feelings of people. The Winx soon learn that their Enchantix is ineffective against the Wizards of the Black Circle, and that only Believix can combat their evil power.
In order for a fairy to earn Believix, she must make people believe in fairies and magic, thus Believix can only be earned on Earth or somewhere where people do not believe in magic. Believix gets stronger when more people believe in magic, which means that if a Believix fairy does not continue to convince people to believe in magic, her powers will weaken. A fairy must have also earned the previous three Fairy Forms: Winx, Charmix, and Enchantix.
Believix enables a fairy to reach the heart of the people and their feelings, giving the fairy new energy and the power to heal whoever is in need. Believix comes with four types of wings: the standard wings, and Speedix, Zoomix, and Tracix wings.
There are levels of power acquired via power sources or magical items.
Gifts of Destiny

In Season 4, when Diana, the Major Fairy of Nature, decides to take part in the Great Revenge of the Earth Fairies, the Ethereal Fairies give the Winx the Gifts of Destiny because their Believix powers are useless against Major Fairies. The Winx used the Sophix powers to bring Diana's forest back to life after the humans harmed it, and to restore the source of the forest's magic. In order to earn Sophix, a fairy must be granted the Gift of Wisdom by the Blue Ethereal Fairy. Sophix allows fairies to magically unite with nature as it is a source of emotional and instinctive energy which merges with the Believix powers to reach the absolute harmony with nature.
- Main article: Lovix (Form)
In Season 4, when Aurora, the Major Fairy of the North, decides to take part in the Great Revenge of the Earth Fairies, the Ethereal Fairies give the Winx the Gifts of Destiny because their Believix powers are useless against Major Fairies.

If a fairy does not complete the Sirenix Quest within one lunar cycle, they will lose their powers forever. 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. Harmonix allows fairies to use their magic easier in mid-air, on land, and underwater. It also helps fairies to swim faster.
- Main article: Sirenix (Form)

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. Then, the fairy's Sirenix Box will appear along with her Sirenix Guardian, who will open the portal to the Infinite Ocean. Finally, Omnia, the Supreme Guardian of Sirenix, will appear with the portal to the Infinite Ocean. Once the fairy crosses the Sirenix Gate, she will earn Sirenix. Sirenix grants its possessor access to the Infinite Ocean and gives fairies and witches the ability to use their magic easier in mid-air, on land, and underwater. It also helps them to swim faster.
- Main article: Bloomix (Form)
In Season 6, the Trix take over Cloud Tower and ally with a witch named Selina, who owns a magic book called the Legendarium that can make legendary creatures come to life. When the Trix attack Linphea, the Winx attempt to fight them, but the Legendarium strips them of their powers, except Bloom (because the power of the Great Dragon cannot be taken from its keeper). Bloom then shares parts of her Dragon Flame with the other Winx girls who will have to perform good actions worthy of a fairy to earn a new transformation. 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. Bloomix gives the Winx their magic back after the Legendarium stripped them of their powers.

They brought with them seven Ancestral Wands which contain the Mythix power, which allows entry into the Legendarium World. However, one must not stay in the Legendarium World for too long, or else they will become fictional characters, stuck in the pages of the Legendarium forever. In order to earn Mythix, a fairy must prove herself before the Ancestral Wands. In turn, the wand she receives will grant her 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.

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). Then, the Winx are forced into their Dreamix forms when they are sucked into a portal leading to the World of Dreams.
The source of Dreamix power is dreams and talents. It grants the Winx the ability of sensing which talented person will be the next target of the Talent Thief (referred to as "Dreamix Vision"), as well as their whereabouts. Since the Winx were forced into their Dreamix after being sucked into the portal leading to the World of Dreams, it is possible that Dreamix is necessary to enter this place. It allows the girls to search on land, midair, and briefly underwater.
