Winx Club

Bloom accidentally unleashes her Winx powers during an encounter with Mr. Knut, who attempts to steal her and Stella's magical abilities. With the help of the Winx and the warriors, they manage to defeat Mr. Knut. After the battle, Stella accompanies Bloom to Alfea for training.

Bloom arrives at Alfea and falsely introduces herself as Princess Veranda, warning that those not on a list will face a slimy transformation. Stella introduces her to the other Winx Club members, but the Senior Witches and Mr. Knut confront her, only to be defeated by the Winx.

The Winx Club and their warrior allies prepare for the school dance while facing a threat from witches attempting to steal Stella's magical ring. Bloom confronts the witches alone and uses her powers for the first time, though she is unable to prevent the ring from being taken.

During a field trip focused on learning to "listen to nature," the girls are unaware that Nutt has informed the witches that specialists are transporting the troll to Magix. Concerned that a mind sorcerer might uncover their secret, the witches rescue the troll. In an effort to locate it, the specialists and fairies join forces, but the witches succeed in making the troll vanish permanently.

Stella is invited on a mysterious date by Prince Sky, but she is soon captured by the witches and Mr. Knut. While the Winx Club brews a potion to make better decisions, one of the witches impersonates Stella and demands her ring in exchange for her freedom, which Bloom agrees to give.

The Winx Club travels to Cloud Tower to retrieve Stella's missing ring, only to find themselves trapped and attacked by a swarm of beetles. As Stella accidentally traps them in fire while trying to defend herself, Bloom hears a mysterious voice guiding her toward an invisible escape route.

The Winx Club and the Red Fountain magicians are forced to clean as punishment for visiting Cloud Tower, but the witches use the opportunity to send a minotaur to attack them. Stripped of their magic, the Winx Club manages to defeat the creature through teamwork and ingenuity. Impressed by their effort, Griselda restores their powers.

On the day of the Rose, which honors parents, most students leave for Magix, but Musa, Stella, and Bloom remain. Stella and Bloom join the race event in Magix with their boyfriends, but tensions rise between Riven and Bloom. Meanwhile, Darcy sabotages the race and casts a spell that makes Riven believe she is his girlfriend.

Bloom is unsettled by recurring strange dreams, but her attention shifts when Stella's unexpected rudeness upsets the Winx Club, especially causing Musa to run away in tears. Musa ends up in Magix, where the witches are present, leading to a confrontation between the witches and the fairies. The conflict escalates until Bloom unleashes a powerful surge of energy, inadvertently revealing the location of the dragon power to the witches.

The Winx girls participate in a virtual reality challenge where each can only use one potion, relying on their magic for the rest. Bloom is the first to enter, but the game is disrupted when the witches attack, push Kikko into lava, and steal Bloom's dragon fire. Bloom and Kikko manage to repair the VR chamber and escape, only to discover the witches never had the dragon fire.

Flora creates a potion to repel witches, but her experiments cause issues for Stella and Techna, leading to a disagreement. She continues her work at Black Mud Swamp, where Bloom and the others join her to retrieve a final ingredient from the Junior League of the Swamp. To earn it, the Winx must defeat a monster stealing food from the swamp, which they succeed in doing, allowing Flora to complete her potion and help the League recover their food supply with her Vegal Cloner invention, mending relationships along the way.

Stella enters the Miss Magix Beauty Pageant instead of preparing for an exam, confident in her chances of winning. But as the competition heats up, senior witches begin sabotaging the contestants for fun, causing chaos. Stella must uncover the truth and save the pageant before it's too late.

Bloom becomes determined to protect her mother's flower shop after it becomes a target of a potential theft.

Bloom discovers the answer to a quiz, realizing she will be expelled if she fails, and Gricelda takes her on an astral journey to reveal Daphne, the voice in her head. While Bloom tries to hide the answers, the other Winx girls attempt to retrieve them, and Flora initially hides them before returning them to the teacher. The girls later learn the quiz was a trick, as the envelope "pops" when opened, testing what happens if someone tries to cheat.

The witches summon a nightmare gargoyle that attacks the Winx Club, draining their strength with each encounter, though Bloom remains unaffected. Mirta, still transformed into a pumpkin, reveals the truth behind the attacks. On the second night, the Winx attempt an ambush, but are overwhelmed by the witches until Faragonda intervenes, defeats the nightmare, and forces the witches out of Cloudtower.

A princess arrives, asserting that she is Prince Sky's betrothed and vowing to prove her claim by competing for his affection.

Bloom returns to Earth, troubled by the consequences of her actions on her friends. Pursued by the witches, she is involved in a confrontation that ultimately results in her losing the dragonfire.

Bloom and the Winx Club travel to the icy palace on Sparks to recover Bloom's lost Dragonfire.

The battle concludes with the group returning to Alfea aboard the boys' spaceship.

The Winx Club and the Red Fountain magicians, excluding Riven, travel from Sparx to Cloud Tower in an effort to retrieve Bloom's lost dragonfire.

The group splits to speed up their search, with Bloom's team discovering dragon fire only to encounter the witches. Riven, Brandon, and Knut arrive with Ms. Griffin, who detains the witches and opens a portal to Alfea for the others to escape. Sky and Bloom remain behind to distract the approaching army of decay.

Bloom and Brandon crash in the forest and receive a mysterious directive to go to Lake Crescent, while Griffin switches allegiance to Alfea and helps defeat the Army of Decay.

The witches launch a final assault on Alfea, pitting the Army of Decay against the combined forces of Red Fountain, Cloud Tower, and Alfea. Bloom retrieves Daphne and regains her powers, while also rescuing Brandon from three Army of Decay creatures in Magix. Meanwhile, Mirta is transformed back into a human and Riven confesses his feelings for Musa.
