Duman

Duman is one of the Wizards of the Black Circle, the main villains of Season 4 of Winx Club.

Duman is the most goth-like of the four, with a mohawk. He possesses the power of shapeshifting, and does so often when he fights the Winx and the specialists. Sometimes he turns into beasts with a color scheme similar to him, other times he takes the form of other characters.

Eventually Duman falls ill from too much shapeshifting, which threatens to kill him. He refuses Nabu's help, turns into a demon, and reveals Ogron's plan to destroy all fairies before beating up the specialists. Furious over his betrayal, Nabu traps Duman in a magic sphere and destroys him.
