Azal is one of the main antagonists of the Doctor Who episode The Daemons alongside The Master and Bok. He is the last of the titular race from the planet Damos.
In his respective story, the Master wanted Azal's power and summoned Azal three times but he wanted to give it to the Doctor or destroy the world as a failed experiment, but the Doctor refused. Then Azal decided to give the Master his power and destroy the Doctor. Jo Grant told Azal to kill her instead. Azal, not understanding her willingness to give her own life for someone else's, was thus destroyed when his own power turned against him in his confusion, and destroyed himself and his ship at the dig at Devil's Hump was destroyed.
