Hecat is the queen of witches.
She is enraged that the main trio of witches have interfered with Macbeth without consulting her, particularly as she thinks little of him, and insists on joining their later interaction with him. She arrives with reinforcements to improve their brew before Macbeth arrives. She is given to bursting into song and taking flight at little notice. Four spirits call for Hecat and induce her to leave the three witches. They are Stadlin, Puckle, Hoppo, and Hellwain. A spirit like a cat (Malkin) descends from the sky to fetch Hecat.
