The Gryffindor Head of House and the Transfiguration professor at Hogwarts. She's an exacting teacher and authority figure, though she also cares deeply for her students and their wellbeing. She acts as a voice of reason for Harry early in the school year, as she shares with her class that Professor Trelawney predicts every year that a student will die and nobody has died yet. Later in the year, Harry becomes very angry with her, as she confiscates his Firebolt broomstick to test it for jinxes. Harry discovers at the end of the school year that McGonagall wrote the letters to get Hermione a Time-Turner so that she could take a double course load. McGonagall is also an Animagus and can turn into a cat with markings around the eyes that mimic the glasses she wears in her human form.
