A supposedly ordinary girl from planet Earth, Bloom lives a perfectly normal life in the city of Gardenia until she meets Stella, a princess from the planet Solaria, who is in trouble. Coming to Stella's aid, Bloom discovers her magical powers. Stella persuades Bloom to join Alfea, the best fairy school in all the realms. She agrees and leaves Gardenia and her parents. She brings her pet bunny Kiko, to remind her of her old home. In Alfea, Bloom forms the Winx, whose members are her four friends and roommates: Stella, Musa, Tecna , and Flora. Later in the series they encounter and befriend the Specialists: Brandon, Riven, Timmy, and Sky. The Specialists will also become their love interests. They will also encounter their enemies, a trio of witches named the Trix: Icy, Darcy, and Stormy. They are witches from Cloudtower, a witch school roughly equivalent to Alfea, and are in search of the power of the Dragon's Flame which is supposedly in Stella's magic ring. Their ruthless pursuit of the ring leads to many encounters and battles with Winx. Bloom also begins to learn the secrets of her planet, real parents, and powers.
