Specialists

The Specialists:
Sky, Brandon, Riven, Helia, and Timmy, all are taught at Red Fountain. They are first seen in the first episode of the first season (except Helia). They first are minor characters but as the seasons progress, they become more major. The Specialists are the Winx's boyfriends.

Helia is introduced in the 2nd Season, but is relatively a minor character because he is not usually seen in the episodes as the other specailists. Nabu, a wizard from Andros, is introduced in the 3rd season, but is not said that he attended to Red Fountain. But he still hangs around with the Specialists.

When Nabu was killed off in Season 4, Roy joins them. Until, Aisha falls in love with Nex.

Nex joins at Season 8.
