Ultimate Story[]

Stella as she first appeared in the Ultimate Story.
Stella made her first appearance in the Ultimate Story special: The Celestial Winx. She and her friends are members of a special group of Winx fairies known as the Celestial Winx, chosen subordinates of the Great Wizard.
There first task was to eradicate an evil entity known as Malicet. She and her friends fought valiantly against the evil entity and were able to be a match against him. However something went horribly wrong during their final battle and Malicet gained the upper-hand against the girls. Knowing that they can be destroyed by him, they decided to sacrifice themselves in order to seal him away so that he can no longer be a threat to the entire Universe. After sealing him away, they vanished with no one ever being able to see them or hear from them again.
4000 years later, Fox saw them in a dream that he had during a deep sleep and found out that the Celestial Winx weren't dead, but rather, their powers are what's keeping Malicet sealed away. However, they've been regaining their powers and their bodies, thereby causing the seal to Malicet's prison to weaken. Knowing how much time they have left, this prompted him to inspire the new Celestial Winx to make the dead line so that they can finally defeat Malicet.
After Layla was released from her evil twin sister and Malicet was finally defeated, Stella and her friends returned to their world only to find that it had been frozen in time since their sacrifice. Immediately after returning, their worlds returned to normal. From there, they were able to celebrate finally defeating Malicet. The girls believed that all is well and that their troubles were behind them. Little did they know was that the worst of it has yet to start.
