Zarathustra

&nbsp Professor Zarathustra is a witch that teaches Mayhem at Cloud Tower and sister of Ediltrude. She is a strong believer in the dark arts and very loyal to Head mistress Griffin. When the Winx Club arrived she and Ediltrude scoffed that the Winx Club would be able to handle their stay at Cloud Tower.
