Stella The Faerie of the sun

Stella is depicted as usually proud and self-centered, though she cares a lot about her friends. Besides that, she loves fashion and gossip, sometimes giving fashion advice to the other members of the Winx Club. She'd rather goof off, shop, or go out with boys than do her schoolwork, sometimes annoying the rest of the Winx Club.

The most intuitive of all of the members, Stella likes to matchmake and has often had problems with understanding why her friends don't always like getting set up. Despite her intuition, Stella can be rather oblivious at times (especially when it comes to her boyfriend, Brandon Stella and her friends also gave her the name of "Fairy of fashion" and as mentioned in Season 2 when she met Amore, her bonded pixie, she called herself "The Most Loved Fairy". In the beginning of season one, Stella is 16 years old.

Although she might disagree with her friends at times, Stella is very supportive and protective and will not hesitate to help them. She learns to accept that love and friendship are far more important than royalty, fashion, and beauty. Sometimes she hides her true personality because of her upbringing, but manages to uncover it in the 4th episode of season 3. Stella, surprisingly, also seems to be a good leader, as she leads the Winx whenever Bloom is absent, which proves that she isn't very irresponsible after all.

Stella's favorite hobby is shopping. Although she hates studying, her favorite subject is metamorphology. Her favorite spell is Moon Ray, one of her rare moon powers, and she loves eating chips.

Stella and Brandon's relationship started out when he asked her to dance at the dance held at Alfea in Alfea College for Faries and she's loved him ever since. In season 1, she felt betrayed when he turned out to be a squire named Brandon, not Prince Sky. She also felt betrayed because he lied to her the whole time. It took her a while to forgive him but she doesn't hold it against him. In season 2, he was held hostage by the Downlanders and was almost forced to marry Princess Amentia. Stella and her friends went to great lengths to save him. Thankfully, they got there just in time. In season 4, when Mitzi was attacked by one of the Winx girls' possessed pets, Brandon rescued her. Mitzi then falls in love with him and kisses him, straining Stella and Brandon's relationship. Mitzi also swears that she will have Brandon in the end. This causes Stella and Brandon to fight a lot, but they manage to make up after a few episodes.

Tecna, The Techno Faerie

Tecna is extremely smart and loves technology.
On the Winx Club site, her profile states that her favorite color is light blue, her favorite animals are dolphins, that she loves sci-fi films, her favorite music is pop and jazz, and her favorite food is spinach. Her favorite subject at Alfea is Electro-Magic and her favorite spell is Laser Ray.
She is always rational, practical, and logical, sometimes to a fault. Tecna has trouble expressing her emotions and bases the majority of her decisions on pure logic, making her seem cold and unattached. Tecna develops emotionally through the series and eventually experiences crying, stating that she never cried before.
She loves computers and video games, and enjoys sports and being active. She also has a strong bond with Musa (her profile states her as her best friend) and they are roommates at Alfea. Tecna also really likes Timmy, a Specialist, but for a while, didn't know how to express her feelings to him. He was also shy around her.
Of all the girls in the cartoon, Tecna's family and home planet are not fully explored or even seen. Even during the period she was thought dead in season 3, the girls seem to not have met her parents, making her more mysterious than Bloom, who has already solved the mystery of her origins. In the comic, Tecna is a princess with a living mother and father, but that is a different storyline and may not be consistent with the animated series should the subject of her family and culture ever appear.
For a little while, Tecna was the main focus for the Winx Club during season 3. In episode 13, Tecna earned her Enchantix by sacrificing herself to save Andros, using her fairy dust to force her way into the portal and close it from the inside. It was thought that Tecna was dead and she would never return, causing the Winx Club to cry and disband the group. Thankfully, Tecna is found in episode 17, still alive and well. With her back, they were officially the Winx Club again.

Tecna's boyfriend is Timmy, the smartest of the Specialists. During season 2, Tecna was very upset not only by Timmy's showing of cowardice against the Trix, but also about his lack of knowledge about anything other than technology.

Tecna's appointed pixie is Digit, the Pixie of Nanotechnology. She is extremely immaculate, logical, precise, and mathematical, but shows little emotion whatsoever. An obvious match for Tecna, the two seemed to have developed a close relationship with each other. They are often seen playing video games together.

Roxy-The last faerie on earth

Roxy is a character in the Winx Club animated series. Her first appearance was in the third episode of the fourth season, "L´ultima Fata della Terra" (The Last Fairy on Earth). She is (or was) the last fairy on Earth. It was largely debated on whether Roxy is a full fairy or a human-fairy hybrid, as the other six Winx Club member's fathers are not shown to be fairies, but still have magical powers, and Klaus is just an ordinary human.

Roxy is good friends with each member of the Winx, but has the closest relationship with Bloom, as the two have very similar backgrounds. Both girls were thrust into the world of fairies after growing up, believing they were normal teenage girls and both grew up in Gardenia. Roxy, however, has far more trouble dealing with finding out the truth about her being a fairy then Bloom did. Unsure of herself and how to use her powers sometimes, she usually goes to Bloom for advice. She also helps Bloom and the Winx girls in some instances too. Roxy believed in the Winx and fairies when they were in danger from the Wizards of the Black Circle, earning the girls their Believix.

Bloom-Dragon fire Faerie

Bloom was born on Sparks  to King Oritel and Queen Miriam. Shortly after birth, her planet was attacked by a coven of witches (the Trix's ancestors) who sought to put out the Dragon's Flame^] from Domino.^[2] During this battle, the entire planet was devastated. In a final sacrificial act to ensure that the Dragon's Flame^[3] did not fall into the wrong hands, Bloom's older sister, Daphne, sent her through a portal that led to another planet, Earth.
On Earth, Bloom was found in a burning building by a firefighter named Mike, who rescued and eventually adopted her. Her adoptive mother was a florist named Vanessa. Bloom led an ordinary life, but she held a strong belief in fairies, even though she was unaware of her true origin. In her youth, she received a gift, her close pet rabbit Kiko, and met her rival, the snobbish and arrogant Mitzi.
Bloom is a cheerful and amiable girl who cares deeply about those around her, especially her friends and family. While she normally carries a gentle disposition, she is prone to be confused and frustrated when something is not right. She is earnest in learning new things, especially her new identity as a fairy, even though her skills were not well-versed in the beginning.
At the beginning of season one, Bloom was 16 years old. Bloom's outfits are primarily cyan, but on the official Winx Club website, her favorite color is red. She loves reading books about spells and playing with her pet rabbit, Kiko. Her favorite subject is Potionology and her favorite spell is the Dragon's Flame. Her profile on the official site also states that her favortie food is pizza. She is very close to Roxy, as they share a similar background.

Bloom is very close to Stella as she was the one that introduced Bloom to Alfea. Bloom shares a room with Flora. At first, the bond between Bloom and Flora is weak but after some time, they became good friends. Bloom does not have much of a problem getting along with the other girls. She is kind and will give a helping hand to her friends when needed. Stella was the first fairy Bloom had ever met and, in addition, their boyfriends were born on the same planet and they are also best friends. In season 4, Bloom meets Roxy and has a very close relationship with her as the two have very similar backgrounds. Bloom was thrust into the world of fairies and discovered her true identity as princess of Domino and had trouble dealing with everything. Roxy who was also thrust into the world of magic like Bloom, and had no idea of her fairy abilities until she met Bloom and the Winx Club and she gave them Believix Powers in Series 4. Bloom's fiancé is King Sky of Eraklyon.
Bloom's bonded pixie is Lockette, the Pixie of Portals. She has a hairpin which transforms into a scepter that points her in the right direction. She uses it to find secrets of Bloom's past all throughout the series. Lockette not only helps Bloom find her way physically, but emotionally as well.

Layla-Morphix Faerie

When we first see Layla in the first episodes of season two, it is apparent that she is determined and fearless. We observe her trying to rescue the pixies that will later become bonded to the individual members of the Winx Club. Through her conversation, we get a glimpse of her powers and receive a few hints about the villain of the season, Lord Darkar.
After escaping with only one pixie, baby Piff, she stumbles to Alfea, where she is found by the members of the Winx Club, and faints. She shows a deep love and care for the pixies, who are obviously her close friends. The Pixies trust her very much - Layla is one of the few people who know of Pixie Village. Layla gives practical advice and always provides a shoulder to cry on.
She continuously shows this caring nature throughout the show, comforting Musa after her conflict with her father, and calming Flora's nerves when she experiences qualms about her feelings for Helia.
She has tried to develop independence. She appears to be a feminist, sometimes conflicting with chauvinistic Riven, and can perform any task that the specialists can. She even, at one point, takes control of the Wind Rider from Riven.
Layla was raised in a very traditional setting. Her parents believed that princesses should conduct themselves in a strict orthodox manner, and scrutinized her every movement and thought. As a result, Layla had a very isolated childhood, excepting the times when she escaped from the palace. Because of this, Layla has not had many friends. After her best friend Anne had moved away when Layla was young, her only friends were the pixies of Pixie Village.
In most of season 2, the show seemed to revolve around Layla instead of Bloom and the other girls, but at the end, it focused on Bloom again because Lord Darkar tried, and temporarily succeeded, to turn her evil.
She is 17 years old when she is first comes to Alfea and her birthday is June 15.
Her first interaction with girls her age comes when she arrives at Alfea. Having been so isolated for such a long time, she held back at the beginning and worried that she didn't know how to be a good friend. As the months progressed though, she slowly opened up and became good friends with all of them.
Layla is a very talented dancer, and was taught to let loose with her dancing by a young peasant girl names Anne, whom she befriended as a young child when Anne escaped from the village and went into Layla's castle.
She is strongly against romantic entanglements with boys. Her parents had wanted her to marry a man called Nabu, but under the name Ophir he helped her various times throughout season 3. When she found out he was Nabu, they had already fallen in love, and by the end of season 3, they were in a relationship.
In the fourth season, Nabu asked Layla to marry him and she happily accepted. However, when the Wizards of the Black Circle attacked Tir Nan Og and threatened its Queen, Morgana, Nabu sacrificed his own life to save everyone. Feeling distraught and frustrated over losing Nabu, Layla accepted an offer to join Nebula and her "Fairies of Vengeance" in an attempt to destroy the Fairy Hunters once and for all. Later on, she rejoined the Winx Club. Layla's signature color is green in civilian, Winx, and Enchantix, but her Believix is turquoise blue instead since Roxy's color is green, too.

Flora-The nature faerie

Flora is sweet, shy, calm, and loves plants of all kinds. She likes to experiment on them and enjoys making tea. Flora is strongly connected to nature and loves helping people. She can be very sensitive and always wants the best for her friends and everyone around. She also loves peace, happiness, and tranquility. Although she tries to hide her true feelings, her friends help and encourage her to share all her ideas with everyone. Flora gets nervous easily but when the other Winx girls are in trouble, she manages to stay calm and reasonable. At times, she does not know how to express herself, because she does not want to start fights. She is a diligent student at Alfea and is cautious of her actions. Although she can be insecure, her friends boost her self-esteem. According to the second movie, Flora is Linphea's princess, though this may not be canon in the series. Also in the second movie, she is shown to own a mobile phone, despite the fact that her home realm, Linphea, is technology-free.

At first, Flora has a somewhat weak relationship with her friends, Bloom, Layla, Musa, Stella, and Tecna but after some time, she grows a stronger bond with them. She cares deeply about them and would risk her life for them. They support each other and stand up for each other, especially when it comes to fighting the Trix. Flora is especially close with Layla, who offered to help her get together with Helia. Flora also has a strong bond with her pixie, Chatta. The two are actually very different; while Chatta is sociable, talkative, aggressive, and bold, Flora is shy, meek, and more gentle. However, because of this, Chatta can easily cheer up Flora and boosts her self-esteem. Flora is also friends with Sky, Riven, Timmy, and Brandon, but not as strong as her other friends.
Flora is crushing on Helia, the new Redfountain boy. He is an eccentric daydreamer and enjoys writing poems. He is a pacifist and rarely uses offensive attacks. However, when Flora was in trouble, he had saved her with his laser string glove, causing her to fall in love with him. Despite her deep feelings for him, she has a hard time telling him how she feels. He returns her feelings, but being shy as well and unsure of how she feels, he has trouble telling her his feelings. Flora's attraction to him is quite obvious, as she does not pay attention in class and doodles his name in her notebook. Layla and Chatta both try to get them together, which consequently leads to the two revealing their feelings to each other. Helia and Flora actually have a lot in common, such as their love for nature, their idealistic ways, and how they prefer to use strategic purposes instead of offensive ones. In the second to last episode of the second season, Flora and Helia kiss, and you can see part of Flora's face as she blushes.

Musa-Music faerie

Her mother died when she was very young, but she loves her father a lot. Her mother had an amazing voice and her father was a pianist, but after her mother's death, her father was devastated and refused music, and even once threatened to withdraw Musa from Alfea for appearing at a concert at Redfountain.
Her birthday is May 30, and her best friend is Layla. In season 3, Musa is the only Winx member who literally tried to claw Tecna out of the Omega Dimension when Tecna got her Enchantix saving Andros. She loves music, dancing, singing, and playing all instruments, her favorite of which is the concert flute. Musa usually plays amazing music, but plays best when she is alone at Alfea in a quiet spot. Despite being a bit of a tomboy, she is the most emotionally vulnerable. Musa compensates by putting up a tough front and is quick to temper. Her emotional weakness is probably a result from her mother's early death and disputes with her father.
Musa can be a bit of a loner, she likes her space, though she developed a crush for Riven. Despite their initial interest at the beginning of season one, Riven began to act cruel towards Musa and the other winx when he began dating one of the trix Darcy. When he came back at the end of season one he apologised to Musa and they became friends. Neither admit they like each other until the end of season two and start dating. Their relationship sees a lot of arguments but they genuinely care for each other.
Surprisingly, Musa gets the best grades of the group, as mentioned in the fifteenth episode of the first season.
In season three, Musa admits she wanted to break up with Riven, but they later reconcile. Later on in the season, she is told by Arcadia to choose between eternal happiness with her dead mother and saving the magical universe. It was a difficult choice for her, but she had to remain loyal to her duty to protect the universe. In doing so, she claimed the final of the Water Stars that would be used to defeat Valtor.
Musa's bonded pixie is Tune, the Pixie of Etiquette. They often annoy each other, due to their polarizing nature. Tune believes in being ladylike, as opposed to Musa who is known for being outgoing and tomboyish in behavior. However, despite these contrasts they balance each other out.
