The planet Domino (Sparks in the 4Kids version) that was the final resting place for the Great Dragon who created the Magic Dimension. Other than princesses Bloom and Daphne, the following characters are from Domino:

King Oritel and Queen Marion: The parents of Daphne and Bloom. They first appear in season 2, episode 9, in Bloom's dream. King Oritel has brown hair and Queen Marion has red hair like Bloom, though Marion's is extremely curly and her hair color is ligher then Bloom's. They are very powerful and a threat to Valtor. They are friends with Faragonda, Griffin and Saladin, who tried to help them in fighting off Valtor. In episode 24 of season 3, Bloom goes to Cloud Tower in search of the Three Ancestral Witches. They reveal to her that Valtor lied to her – her parents are not trapped within him, as he pretends they are, but that her parents are still alive in a place beyondmagical dimension's reach. It is revealed in the movie that King Oritel and Queen Marion are trapped in a dark realm called the Circle of Obsidian with the Three Ancient Witches themselves and an evil sorceress named Mandragora.

In her youth, she was an Alfea student and, after many travels across the magical universe, became the guardian of the lost Library of Alexandria where she had guarded the Legendarium. On meeting Selina she found that the young girl had great magical potential and decided to become a fairy godmother. However Selina's demeanour changed because of the Legendarium and she chose to become a witch instead of a fairy. Eldora now lives in Gardenia and flowers are her passion.

Lu Wei: The last dragon tamer from Earth. He lives in China.

Artu: Roxy's pet dog. Ivan Andreani voices Artu in the Italian version. Artu has pale brown fur and pitch-black eyes. Like Kiko, he displays an unusually high amount of intelligence for a dog, but only Roxy notices this.

They live in the oceans of the Magic Dimension and some are the guardians of the gates under the ocean. Tritannus stole their powers to get access to the Infinite Ocean. Their powers are restored when a fairy from their respective home planet bonds with them. Selkies can also sense when their bonded fairy is nearby. Based in part on the selkies of Gaelic folklore.

They first appear in the fourth season where they were originally soft toys from Earth brought to life by the Winx's magic.

Belle: Bloom's pet lamb, she has white fur, orange/yellow eyes, and green hair with two red bow ties on either side. She loves adventure and always tries to make fun out of everything.

Ginger: Stella's very pampered pet poodle, she loves new outfits or accessories, and is similar to Stella in terms of being more concerned about her appearance then much anything else. Like Milly, she usually fights for Kiko's attention. Ginger is shown to also be very lively.

Coco: Flora's pet kitten, she shares Flora's love of plants and flowers, and loves to cuddle with those around her, no matter their alignment or personality.

Pepe: Musa's pet teddy bear, he is small, with brown fur, large purple or light green eyes. Pepe loves to dance, but sometimes eats a little too much.

Chicko: Tecna's pet duckling, she is small, with yellow feathers, orange eyes, and a small hairband on top of her head that ties together three little hairs. She is very into video games and technology just like Tecna, but also loves to play and is very lively.

Milly: Aisha's pet bunny, with white fur, blue eyes, and light pink hair. She wears two orange hair ties with yellow flowers on her ears. She enjoys working out and fights for the attention of Kiko.

Magical beings bonded to the fairies. Each has a special talent similar to how each fairy has a specific power. All known pixies are female, yet in the Italian show Pop Pixie, Digit, Tecna's pixie appears as a male. They make their first appearances in Season 2 after Aisha, Bloom, and Stella rescue them from Lord Darkar. Based in part on the pixies of British folklore.

Lockette: The Pixie of Portals, and Bloom's bonded pixie. She got herself lost, and is constantly on a journey to discover the secrets of her past throughout the series (or 'has many hidden passages in her heart'). Lockette not only helps Bloom find her way physically but also emotionally, as she tries to discover her true self, and connect with her power and family. Lockette's guidance and loyalty saves Bloom on many occasions, and the two are inseparable (much to Kiko's dismay). Lockette like the other pixies does not return in Season 5.

Amore: The Pixie of Love, who lives up to her name. Her sensitive nature is mirrored in appearance by her rosy-red hair, flowing pink dress and floral decorations. She is Stella's bonded pixie. As Stella's bonded pixie, Amore reminds Stella of what is truly important in life: Love. Amore's belief in love as being beautiful and Stella's love for beauty, complement each other perfectly.

Chatta: The Pixie of Gossip, who looks somewhat like Stella: long, blonde hair in two ponytails, with a yellow outfit. She is extremely talkative and open-minded and enjoys writing cheers, and talking about just everything, especially herself. Chatta is also the bravest of the pixies, as she once stood up to Darkar in a Season 2 episode. As Flora's bonded pixie, Flora is very dependent on Chatta, due to Flora's respectively extremely introverted but quiet nature and Chatta's extroverted and talkative personality, which complement each other. Chatta encourages Flora to find the strength to speak her mind, often showing the most positive of outcomes. She also helped Flora tell Helia about her feelings about him (It has been noted and sometimes mistaken that Amore and Chatta could also have fit with each other's associated fairy, due to Amore's floral decorations and Chatta's blonde pigtails and attitude).

Tune: The Pixie of Etiquette or Good Manners, who is polite, even when she is yelling at others. Tune is neat, orderly, prim and proper, old-fashioned with pale purple hair, and a Victorian style outfit in purple, white and blue. Tune believes in being ladylike, a stark contrast to her bonded fairy, Musa, who is famous for her outgoing behavior. In spite of Tune's nagging and correcting, Tune and Musa make the perfect pair, each lessening each other's extremes. A perfect example of 'opposites attract'. Her last appearance as Musa's pixie was in season 4.

Digit: The Pixie of Nanotechnology (technology on an extremely small scale), who lives up to her name. She is extremely immaculate, logical, precise, mathematical and shows little emotion. She is an obvious match for Tecna, and the 2 have an extremely close relationship, as Digit and Tecna are perfect for challenging each other's minds (and video game skills), discussing similar interests, and speaking in their technical manner. Her last appearance as Tecna's pixie was in season 4.

Piff: A baby Pixie of Sweet Dreams, who can turn any nightmare into a sweet dream by falling asleep on someone's head. Piff is unable to talk (so she mostly communicates in baby babble), and depends on Aisha, staying always by her side (or in her hood). Piff is almost always sleeping, and is the perfect match for the restless Aisha, who often tosses and turns in her sleep due to nightmares. Piff also might fall asleep while flying, so Aisha and other pixies must be real quick catching her. Aisha and Piff have an extremely close bond, as Aisha needs Piff to function, and vice versa. They even appear to be a perfect fit visually since Piff was the only pixie she saved.

Caramel: The Pixie of Super-strength. She replaces Digit as Tecna's pixie in season 6.

Cherie: The Pixie of Weather. She replaces Tune as Musa's pixie in season 6.

The main school for witches in Magix. Faragonda warns the new Alfea students not to meet them.

Griffin: The Headmistress of Cloud Tower. She is a good friend of Faragonda. Griffin can seem mean, but she honestly cares for her students and will defend them if threatened. In season 3 it is revealed that as a young witch, she once teamed up with Valtor to work for the Ancestral Witches, though she eventually switched to good and ran from Valtor. She went on to help defend Domino alongside Ms. Faragonda and Saladin against the Ancestral Witches. She seems to be very grateful to the Winx, as they have saved her and her school many times. She is also a very good astronomer as revealed in season 2.

Editrude: a witch who works at Cloud Tower and is the sister of Zarathustra. She teaches hexes at Cloud Tower.

Zarathustra: a witch who works at Cloud Tower and is the sister of Editrude. She teaches mayhem at Cloud Tower.

Lucy: Mirta's only real friend at Cloud Tower. Tall and pale, Lucy has self-esteem problems and desperately wants to befriend the Trix in the 1st season, once being tricked, as part of a cruel joke, into entering the Miss Magix competition by the Trix after they used a spell to make her pretty only to be turned back to her original appearance by them. In season 2 we learn that she and Mirta have been friends since childhood. In Elementary school, Lucy was popular while Mirta was bullied, however they rejected her when they found out she was a witch. She and Mirta became friends after that. Lucy is intensely proud of being a witch, and Mirta's rejection of dark magic was taken as a personal insult by Lucy. Even though their relationship wasn't very good between the 1st and season 2, Mirta and Lucy are still very good friends. In season 3 Lucy was, like the other witches, controlled by Valtor to attack Alfea, much to Mirta's dismay. Lucy informed Valtor that the Winx were heading to Flora's home world and later helped Griffin to get Cloud Tower back.

The Red Fountain School of Specialists is a school in Magix that trains the male populace in various abilities. Its attendees are known as Specialists, who end up serving on squads. They interact with the Winx and the other fairies at Magix.

Sky is introduced as the crown prince of Eraklyon. He has fair skin tone, deep sky blue eyes and longish golden blond hair but in season 4 he cut it to short ones, then in season 5 he left a long fringe. He and Bloom developed a romantic interest between each other throughout the series. He and Brandon are the strongest of the group and among the best students at Red Fountain. He is best friend with Brandon and is Bloom's official boyfriend also later became fiancé. In season 1, he pretended to be Brandon because Yoshinoya tried in the past to capture the prince & usurp the throne; this name-swapping caused an extreme amount of confusion and upset Stella and Bloom, as the boys they regretted so much that they had lied to them. When Lord Darkar possessed Bloom and turned her evil, his love for her returned her to herself. He was engaged to Princess Diaspro, but broke off the engagement because she was selfish and spoiled, and later had her banished for placing a love spell on him that almost made him kill Bloom but with Stella's fairy dust, he was freed from the spell. In Winx Club: The Secret of the Lost Kingdom, the first movie, he is crowned as the King of Eraklyon.

Brandon is Sky's squire. He has short brown hair with a long fringe, tan skin tone and brown eyes as well as best friend and also Stella's official boyfriend plus fiancé. He's the most outgoing of the boys and is very easy to get along with, but is also the first one to stand up for his friends. Despite his confidence, Brandon shows some insecurity about his position as Sky's squire because he does not believe it is compatible with Stella's position as a princess.

Riven has medium skin tone together with short, spiked, raspberry hair and violet eyes. A lone wolf, very competitive, really easy to get jealous but good at sports, he is also very stubborn. His mother left him at his birth and so he is wary of women in general. He is Musa's boyfriend and although the couple occasionally have some flaws in their relationship, it has been improving and blossoming by the end of the fourth season. At first, Riven had a connection with Cloud Tower because he was controlled under a spell which Darcy cast on him, until the witches realized they did not need him anymore and locked him up. (In the RAI version, he went over to the dark side as a spy willingly and while he was imprisoned, the witches used his guilt over what he had done to torture him – betraying his best friends and helping the Trix almost made him kill Musa.) Luckily, in both versions, he escaped and rejoined the good guys. His weapon of choice is either a reddish purple phantosaber or a meteor hammer. Riven was Musa's official boyfriend and was Nabu's best friend but is now Roy's best friend.

Timmy has medium skin tone, light brown-orange hair with a small fringe and wears glasses with his small hazel eyes. He comes from a family of reputed scientists from Magix. He loves technology, and flying ships from Red Fountain. His aptitude for technology makes him the perfect boyfriend for Tecna and he is also Helia's best friend. He is sweet but shy, even seeming cowardly at times. In Season 2, he is so bashful that it interferes with him telling Tecna how he feels about her. He is the least skilled of the Specialists in terms of combat but an expert when technological methods are required.

Helia is an artistic student, he is a great pilot and a pacifist. He is a nephew of the headmaster of Red Fountain, Saladin. Helia has long blue-black hair tied into a loose ponytail in the second and third season but cuts it to short spiky fringes in season 4, He has medium skin tone and light steel blue eyes. He is also very romantic and extremely shy about directly speaking about his feelings. He is very good at using his laser string glove and tries to help everyone with it. He came back for his second year at Red Fountain and joined Sky's squad. Helia is the oldest of all the boys because he would have been in his third year at the start of the 1st season if he had not dropped out to go to art school. Both Helia and Flora love nature and cannot bear to see someone harm it. Helia is best friend with Timmy and is Flora's official boyfriend. Flora was worried that he would leave her for Princess Krystal, but he assured her that he would love her and only her for as long as he lived.

Staff members include:

Professor Saladin: The headmaster of Red Fountain and Helia's Uncle. He is an old, very powerful wizard. It is revealed in season 3 that he, Faragonda and Griffin helped defend Domino against the Ancestral Witches.

Professor Codatorta: The vice-principal who serves as the Head of Discipline at Redfountain. Not much is known about him other than that he is very robust and active and that he was once a Templar of Roccaluce.

Athena: The guardian of Redfountain's Codex. She wears a Greek goddess dress because her name comes from the goddess of wisdom and battle in Greek mythology. Athena lives up to her name, she is not like the teachers at Red Fountain and rarely shows herself. She is one of the four powerful pixies in the realm of Magix.

Bishop: A specialist with a purple ponytail on top of his head. He has markings on his forehead.

Jared: A dark-haired specialist that has a crush on Musa in season two. Darcy uses him to sabotage the test the Winx take in the simulation lab. He and Musa end up as friends, but by the end of season two Jared is seen with a new love interest, a fairy named Alice.

Others include:

Nabu: (Season 3–4; recurring in 5): A wizard of nobility born in Andros the same planet Aisha is from. He was engaged to Aisha and secretly left his home planet under the identity of "Ophir" to discover who his would-be wife was and find out what she was truly like. The Winx and the Specialists thought that he was a spy for Valtor. He saved the team on multiple occasions and helped defeat Valtor. He gained Aisha's trust and love. He also joined the group on Earth in the fourth season. He used a magic staff as a weapon. Nabu had very long dark reddish brown hair, often braided or tied. Like Aisha, he also had African appearance, although his skin tone was fairer like light brown. Even though he was not a Specialist, he was a close friend of the Specialists and the Winx, certainly best friend of Riven. Nabu sacrificed himself to save the Earth fairy kingdom of Tir-Nan-Og. He later died in Season 4 while saving the Earth fairies from a trap laid by Ogron. He later appeared in the Season 5 Episode The Shimmering Shells, during Aisha's test of Self Confidence.

Roy: (Season 5–6): A new Specialist from Andros, who works for Aisha's father. Roy has short, spiky light blond colored hair with gray eyes and medium brown skin tone with African appearance. Like Nabu, Roy also has the ability to use magic. He is very helpful to the Winx because of his ability to fight underwater. He has a crush on Aisha secretly that seems to begin when they were at a party. He shows interest by wanting to cheer her up. Though Aisha was slow to show that she reciprocated his feelings, she openly shows these feelings by Season 6. Roy and Aisha are not officially dating. Later on in Season 6, he gains a rival for Aisha's affection in one of the Paladins.

Alfea is a fairy school in the Magic Dimension. Students enroll for 3 years and must come with a letter of recommendation, but can be expelled if they break the school's rules.

Faragonda is the Headmistress of Alfea. She is a kind-hearted soul who cares strongly for her students. However, she will not put up with nonsense and will dispense discipline when needed. She teaches Convergence to the fairies of Alfea. Faragonda has a good relationship and a little bit of a rivalry with Ms. Griffin of Cloud Tower, another school for witches in the series. In season 3, it is revealed that this is because they, and Headmaster Saladin of Red Fountain alongside Oritel and Marion, had worked together to help defend Domino from Valtor and the Three Ancient Witches. Apparently, Faragonda was friends with Bloom's parents, King Oritel and Queen Marion of Domino, and was deeply disturbed by their disappearance. Faragonda is also a former fairy godmother. In season 7, the Winx visit her when she went to Alfea, and Stella almost says that she will be the headmistress.

Griselda is the assistant to Ms. Faragonda and Head of Discipline at Alfea. Griselda is the strictest teacher in Alfea. She teaches the fairies a system of techniques involving defense and reflection abilities as well as new spells.

Knut is an ogre who originally works for the Trix. He is near-sighted; a running gag in the first season is that he has to help the Trix or he will be forced to always wear hisglasses. He later changes to the good side out of fear that the Trix will target his kind next. He then becomes a janitor at Alfea.

Wizgiz is a leprechaun teacher of metamorphosis, the ability to shapeshift into various creatures.

Palladium is an elf who teaches Potionology at Alfea. In an early season 1 episode, the Winx girls remark that he needs more confidence in leading his students. He also is in charge of the Magical Reality chamber, as you can tell in the middle of season one and a couple times in season 2 and 3. Between the first and second seasons, he undergoes an evolution and is now a more confident character with an older appearance.

Roxy is the Fairy of Animals and the last fairy on planet Earth. She is from the realm Tir Nan Og. Her first appearance is in "The Last Fairy on Earth," the third episode of season 4, when Stella had closed the curtain on her. Roxy has light skin tone, straight waist-length magenta hair with long bangs half golden colored and violet eyes. She has taken birth on June 9. The six Winx Club fairies' new mission is to protect Roxy from the 4 Wizards of the Black Circle, who are after her. Her exceptionally strong magical abilities center around animals, meaning that she has animal-related abilities and spells that take on the forms of animals. She also lives in Gardenia, just like Bloom, and the two are quite close friends. The Winx girls noticed her in the Frutti Music Bar, where she and her father Rick work, and got to be friends with her later in the season. She owns a pet dog, Artu, whom she loves and cares about very much. She despises anyone who tries to hurt him. Roxy is very much her own person and in the beginning it was hard for the Winx to get through to her. She has quite a stubborn, headstrong and willful personality, but softens as she gets to know Bloom and her friends. It is later revealed that she is the daughter of Morgana, the Queen of Earth's terrestrial fairies, making Roxy the Princess of all of the Earth fairies and rightful heir to the Earth fairy throne of Tir Nan Og. At the end of season 4, Ms. Faragonda shows up at the Frutti Music Bar, where Roxy then takes her offer of going to Alfea with the girls and study more powerful fairy magic in the hope of becoming a full-fledged fairy of animals. Her signature colors are lime green and Spring green.

Daphne is the Nymph of Sirenix and derives her magical powers and spells from the sea and the five elements. Daphne has fair skin tone, knee-length blonde hair and light brown eyes. She is the eldest child of Oritel & Marion of Domino ("Sparks") and Bloom's older sister. She is an important character in Bloom's past. She guided Bloom throughout the first three seasons and helped her numerous times, and later assisted her younger sister in restoring Domino and freeing their parents by defeating the Ancestral Witches in the first movie. In season 5, it was revealed that Daphne was the last fairy to have achieved the Sirenix power. Unfortunately, the Three Ancient Witches had cast a curse upon her Sirenix powers, causing Daphne to become a bodiless spirit. Bloom eventually used her Sirenix wish to have the curse of Sirenix broken forever. This successfully restored Daphne to her physical. In season 6, Daphne finally reconnects with her Sirenix powers and orders the beast of the depths used by the Trix to return to the sea. Daphne later enrolled at Alfea as the History of Magic teacher. She is now officially Crown Princess of her home world. She was Thoren's official girlfriend but eventually married to him in the last episode of 6th season. Her signature colors are cyan, light sea-green and light yellow. She took birth on May 3.

By the end of the 1st season, she is turned back into a girl and becomes a transfer student to Alfea.

Amaryl: Wears a yellow and green fairy outfit and has pink and orange wings. She has a bit of an attitude and sometimes she is comical. She also almost always wants to be center stage and, depending on the person, can or can't hold grudges for long. Amaryl may have a friendly relationship with Mirta and Lucy, as she can be seen with them at Musa's concert during season 2 and 3 of them are invited by Musa to come on stage with the Winx for the last song. She and Stella didn't get along very well through the 1st 2 seasons, as Amaryl had tried to attack Stella in 1 of their classes. At the end of season 3 Stella and Amaryl have put aside their conflicts.

Francis: Wears a harlequin fairy outfit. She might be the fairy of comedy or maybe the fairy of happiness, judging by her costume, or maybe is a vision fairy like Jolly. She is friendly, seeing as she hands tissues to everyone while Musa sings a sad song, but definitely as an attitude has she mocks Timmy when he comes looking for Tecna in one episode of season 2, during Tecna's phase of hating Timmy.

Politea and Daphne fought against the Ancestral Witches to protect the Magic Dimension and the Infinite Ocean, but she betrayed Daphne to the Ancestral Witches and they placed a curse on Sirenix which turned Daphne into a bodiless spirit and Politea into a monster who lived in a cave in the Infinite Ocean. Darcy and Stormy stole Politea's Sirenix and she simply faded from reality when her Sirenix powers were drained.

A supremely powerful and dangerous sorcerer who had learned powerful dark magic on Earth from the terrestrial witches. He had created the Legendarium book and tried to use it to become the strongest and most feared sorcerer of the magical universe but was unable to control its powers and ended by being trapped within the very pages of his own creation. He eventually managed to persuade Selina to work for and become strong enough to release him in exchange for granting her great powers and knowledge about harnessing all of the evil powers of the Legendarium to their maximum potential. Once released by Selina, however, he turned against his loyal servant and was later defeated by Bloom by trapping him inside the Infinity Box.

The main villain in season 6. She is from Earth and is a freshman at Cloud Tower. She owns a magical book called the Legendarium that has the power to make legends come to life. She is quite protective of the Legendarium and will go to any means to make sure that is safe and does not fall into anyone else's hands. In reality, she was willingly working for and obeying the orders of a sorcerer named Acheron, who was sealed within the Legendarium and who she promised to release in return for extraordinarily strong powers, and knowledge on how to harness all of the evil powers of the Legendarium to their maximum potential. She was revealed to be a childhood friend of Bloom's, long before she and Bloom, had found out she was a fairy and they both lived in Gardenia as "ordinary girls".

The main antagonist for the fifth season. He is Aisha's cousin, the son of King Neptune and Queen Ligea, and the brother of Prince Nereus. He was once a normal merman who was sent to prison after trying to kill his twin brother Nereus (who was chosen to be King Neptune's heir to the throne instead of Tritannus) and was stripped of his prince title. He was later mutated into a horrible monster due to toxic pollution and wanted to rule the whole Magic Dimension by absorbing more pollution to become more powerful and by trying to gain the ultimate power of the Infinite Ocean itself. He stole Daphne's Sirenix powers and gave it to the Trix. He and Icy used to flirt and later entered into a romantic relationship, much to the annoyance of Stormy and Darcy. But he betrayed Icy after he activated the Emperor's throne and gains the ultimate power of the Infinite Ocean, which turns him into a monster in both body and spirit. In the end, he is defeated by the Winx after Bloom destroys his Trident where all of his evil powers were stored. Tritannus is banished to Oblivion for his actions, but in the movie Winx Club: The Mystery of the Abyss, he is freed by the Trix in order to get the ultimate power of the Infinite Ocean, the black pearl.

The four main villains of the fourth season, who were responsible for the disappearance of fairies from Earth and imprisoning all of the Earth fairies. At some point, they had developed a way to resist fairy magic, which allowed them to capture the fairies of Earth, and steal all the magic from the planet. Throughout the first half of the season, they battle the Winx and almost every time the fairies barely make it out alive. However, as time went on the Winx earned Believix and became more accustomed to fighting them, and eventually were able to give them a real fight. They are defeated in the middle of the season by Bloom, with help from Roxy, who used her Believix powers to convince all of the humans in the area to believe that magic and fairies do indeed exist. This rendered all of the Wizards' powers useless, and made them vulnerable to Bloom's attack. In the beginning of the second half of the season, it is revealed that they are still alive, but their powers are weaker than before and they must hide in the sewers. Later on in the season, the Fairy Hunters claim to be good when Duman falls ill. Duman is taken care of by Sibylla, the Fairy of Justice afterwards, though his power goes out of control and he has to be killed. In the season finale, Ogron, Anagan, and Gantlos are frozen forever in the Omega Dimension. While all four Hunters seem to share certain powers, like opening a Dark Gate to capture fairies and cast dark enchantments, they also have individual powers.

Ogron

The leader of the Wizards of the Black Circle. He can absorb and deflect magic. He becomes much stronger and more powerful with every blow of fairy magic he absorbs.

Duman

A shapeshifter who can turn into animals and take on the appearances of other people. He dies from an illness that was a result of his unstable powers.

Anagan

Possesses superhuman speed.

Gantlos

An evil witch who has power over insects and is one of the main antagonists of Secret of the Lost Kingdom. She is the guardian of Obsidian, the realm of pure evil and serves the Ancestral Witches. Bloom and Sky defeated her and the Ancestral Witches in Obsidian, thus restoring Domino to its former glory and saving Bloom's parents and all the inhabitants of Domino.

Three ancient witches who attacked Domino in an attempt to obtain the power of the Dragon Flame but were defeated by the Company of Light. However this destroyed Domino by freezing the whole planet, darkening it and petrified and imprisoned all of its inhabitants, including the king and queen of Domino, in the Obsidian Dimension along with the three witches themselves, whose bodies were consumed by the evil of Obsidian and became bodiless spirits. Some time earlier they tried to invade the Infinite Ocean but had to face the nymphs Daphne and Politea. However Politea betrayed Daphne and the witches cursed the Sirenix power that Daphne and Politea possessed, turning Daphne into a disembodied spirit and Politea into a monster. In "The Secret of the Lost Kingdom" the Ancestral Witches found out that the keeper of the Dragon Flame, Bloom, was still alive and used their servant Mandragora to lure her into Obsidian and kill her but were defeated thanks to Sky, Bloom and Daphne. This however freed the witches and with the help of the Trix they tried to destroy all good magic in the universe in Winx Club: Magical Adventure, but they were finally destroyed by a Believix convergence of the Winx Club.

In the French novel adaptation of the movie, the three evil spirits: Belladonna, who has power over ice; Lysslis, who has power over darkness; and Tharma, who has power over storms. It is hinted that they resemble the Trix witches of Icy, Darcy, and Stormy, respectively. It is rumored that they are the ancestors of the Trix.
