In season 1 there are 5 members of the club, Bloom, Stella, Flora, Musa and Tecna. In this season their fairy transformation is called Winx
In season 2 a new member joins the club. Layla (Aisha in Italy-which is where Winx Club was made.) Their powers then advance to Charmix.
In season 3, there are no new members but stronger bonds of friendship. Their fairy stage becomes, Enchantix.
In season 4, the Winx meet 'The Last Faerie on Earth' named Roxy, of whom it is uncomfirmed whether she is a Winx or not. During this season, the girls earn their Believix, as well as the side transformations Zoomix, Speedix, Tracix, Lovix and Sophix.
The second stage of the girl's fairy form. They get a cute little bag that matches their personality or power, and then a little charm on their top. It is earned by showing your true inner self or by really believing in yourself and showing a great deal of confidence in yourself, or your friends.
