The Trix are sent to Light Haven, a place to turn evil minds pure and good. Bloom, Stella, Flora, Tecna and Musa discover a new fairy, Layla/Aisha, who's the fairy of water/waves and morphix fluids from planet Andros and she becomes the sixth member of the Winx Club. Lord Darkar releases the Trix from Light Haven and increases their powers. Layla/Aisha tells the others about how the pixies are being held as Lord Darkar's prisoners.

At an opening of the new Red Fountain, Flora meets her love interest, Helia. Along with Layla, Lord Darkar is after four pieces of a magical artifact called Codex, which allows one to enter the realm of Realix and gain the Ultimate Power. Bloom wants to know more about her birth parents, King Oritel and Queen Marion, and her lost kingdom, but Darkar gives her a shadow virus. The virus turns Bloom evil and she begins to taunt Timmy . After Lord Darkar realizes that he needs more magical strength and power to open the gateway to Realix, he instructs Avalon to turn Bloom evil once again. That is when he ditches the Trix and accepts Dark Bloom as his main witch. When they get to Realix, he tells Dark Bloom to give him the Ultimate power so he can rule. Dark Bloom has almost completed the spell when the Winx arrive, along with the Specialists, Faragonda, Griffin, and Corta Torta. Sky tells Dark Bloom his true feelings for her, which changes Bloom back into her normal self,and she uses the Ultimate power to defeat Darkar once and for all.
