Fairy Form/Winx Club

Standard
These levels of power are gained during a fairy's formal education journey to become a full-fledged fairy.

Winx
In Season 1, Stella introduces Winx when fighting Knut in Gardenia Park. Faragonda adds the word ”Winx” to Alfea’s vocabulary at the end of the season, stating it to be the definition of a modern fairy, making Winx 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.

Charmix
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, such as a strong fear or a certain weakness holding them back. Charmix boosts the magical energy of a fairy for a short time, making her more powerful and allowing her to use magic in more diverse environments. However, it can run out of energy quickly and drain its user's strength over time.

Enchantix
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
After Enchantix, there is an infinite number of levels a fairy can reach. Higher Fairy Levels are meant for specific situations.

Believix
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. It gives 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.

Butterflix
In Season 7, the Winx find their Bloomix powers to be ineffective against Kalshara. They acquire this form in the Valley of Fruit of the past during their quest to find the secret of the Digmoles. In order to earn Butterflix, a fairy must prove themselves worthy as the true defender of the Fairy Animals. As the essence of nature, Butterflix grants its users nature-based power. However, it cannot damage nature itself.

Powers
There are powers acquired via power sources or magical items.

Gifts of Destiny
The Gifts of Destiny are the evolution of the Believix power that are used to combat the power of the Major Fairies. One of the Gifts of Destiny, the Black Gift, is not a Fairy Form, but a spell to save one person from death.

Sophix
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 use the Sophix power to restore the heart of Amazonia and the source of Diana'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 absolute harmony with nature.

Lovix
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. The Winx use the Lovix power to battle Aurora's forces and protect themselves from the cold. In order to earn Lovix, a fairy must be granted the Gift of Heart by the Green Ethereal Fairy. Lovix protects its users from the cold and implements in them ice and cold-based powers.

Harmonix
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. 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. After finding and unlocking the Sirenix Book, the book gives each of the Winx a Sirenix Box which contains their Guardians of Sirenix who grant them Harmonix. 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.

Sirenix
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. 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 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. 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.

Bloomix
In Season 6, the Trix take over Cloud Tower and ally with a witch named Selina, who owns a magical 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.

Mythix
In Season 6, the Winx search for magical artifacts to lock the Legendarium for good. In their search, they go to Tir Nan Og and attempt to acquire the Ancestral Wands. In doing do, they learn that long ago, seven Ancestral Fairies crossed over from the Legendarium World to the real word and spread their magic throughout all the worlds of the Magic Dimension, including the Earth. 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 insight" or "Mythix vision". The wands are also used as a homing device for the Fantasy Emerald and the Silver Spear.

Tynix
In Season 7, after the Winx's Fairy Animals find the magic harmony among them, they reveal themselves to be the guardians of the Ultimate Power of the Fairy Animals and bestow the Tynix Bracelets upon the Winx. With the bracelets, the Winx can miniaturize and access MiniWorlds, dimensions where the next phase of the Winx's search for the Ultimate Power will commence. In order to earn Tynix, a fairy must be granted a Tynix Bracelet by their bonded Fairy Animal. 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. Tynix transforms bonded Fairy Animals into magic mounts. In "Tynix Transformation," Roxy says the Winx and their animals were only gone for a few seconds, confirming that time moves faster in the MiniWorlds.

Cosmix
Cosmix is the power of the cosmos and originates from light. In Season 8, the Winx find their Butterflix powers to be ineffective against the Staryummies and their holes. They then acquire this form from Queen Dorana in order fight against Obscurum and the Staryummies. In order to earn Cosmix, a fairy must receive the Cosmix power granted by the Queen of Lumenia. Cosmix grants its users light-based power. Being so, it allows the Winx to give back light to all the dying stars cores. The power also lets the girls close/destroy the traversing black holes.
