Season one Overview

In the first episode of the first season, Bloom, a red-haired teenager from the Earth city Gardenia who is obsessed with fantasy stories and fairies, stumbles upon the fairy Stella, who is locked in combat with an ogre named Knut and several small ghouls

Knut and the ghouls are about to defeat and capture Stella when, frightened by the monsters, Bloom unwittingly lets off a magical blast; this directs Knut's attention at her, and gives Stella an opportunity to counter-attack with her own specialty, an attack from her scepter. Knut and his monsters escape, and an exhausted Stella faints. Bloom, concerned about Stella's condition, brings her home to recover.

When Bloom wakes up the next day, she thinks this was all a dream and reflects on what happened the previous day. Later, Knut and his ghouls return with a more powerful Hunter Troll determined to capture Stella. As Knut and the Hunter Troll are about to defeat both Stella and Bloom, the specialists from Red Fountain arrive and repel Knut's attacks and capture his troll.

Stella, impressed by Bloom's power, invites Bloom to attend Alfea, a school for fairies in training. At first, Bloom's parents are skeptical, but Bloom's interest in her innate magical power convinces her parents that her attendance would be in her best interest, and they allow to her go hone her skills as a fairy.

Over the course of the series: Tecna, Flora and Musa are introduced and form the Winx Club, with Bloom as the informal leader of the group; the conflict between the girls and a rival clique from another school called The Trix consisting of Icy, Stormy, and Darcy; The Trix form to search for the powerful Dragon's Fire, an omnipotent force that can control the whole of the Magic Dimension, and are convinced that one of the Winx Club members has it.

Although not Japanese, Winx Club shares many traits with Magical girl anime genre cartoons. There are transformation sequences, magical characters, announced attacks, and of course, a romantic subplot. The average age group the show is targeted at is 7-18.

Season two Overview

In this second series, most the characters from the first season return to continue the series as well as introduce new characters. In the first episodes, the Winx Club members return to Alfea after their summer vacation to begin their second year. As Bloom meets again with the other members of the Winx Club, she suddenly becomes separated and wanders deep into the halls of Alfea pursuing a flying seahorse-like creature. The creature leads her into the classroom of the resident teacher pixie that tells her that their meeting is nothing short than fate and proceeds to tell her future.

In the vaguest of terms, she tells Bloom that she will meet a new friend, a new enemy, and have an adventure unlike any other. About this time, the scene changes to show Layla climbing a giant stalagmite. When she reaches the top, she finds her friends, a group of pixies, confined behind a magical barrier. As she helps these pixies escape, she set off alarms and attracts the attention of Lord Darkar. Lord Darkar persues and recaptures all but one of the escaped pixies and throws Layla (and her pixie) off a cliff. As Bloom and the other members of the Winx Club leave Alfea, a visually shaken Layla wanders onto Bloom's path and collapses.

Over the course of the series, Layla explains her reason for being in Shadowhaunt and requests help to rescue the pixies, in which the Winx Club and specialists oblige. About this time, Lord Darkar seeks additonal members for his plans and finds that help in the Trix girls. Lord Darkar aids in their escape and gives them jewelery ("Gloomix") that will increase their powers. But then something more terrible than all this reign of evil happens. Bloom turns to the dark side when the Professer Avalon hypnotizes her and brings her to Lord Darkar to activate the Codex.
