Fairy Form

Fairy Forms or Transformations are different levels of power that fairies can attain as an extention of their magical abilities.

Overview
Fairies' abilities are limited in their civilian forms. To increase their magical abilities, they transform into fairies and are able to use their powers with greater ease, gain wings, and new clothes and accessories. There are standard fairy levels, which are gained during a fairy's formal education journey to become a full-fledged fairy, and an infinite number of higher fairy levels and acquired powers meant for specific situations.

In Winx Club, the Winx have attained thirteen levels of power, beginning with Winx, and most recently earning Cosmix.
