"Oh in the name of stuffy old ninnies everywhere, what is going - POTTER!"
- Professor McGonagall
Professor McGonagall is the Headmistress of Hogwarts during Harry's Senior Year, appearing in A Very Potter Senior Year. She is stern but considers herself a "very reasonable uptight bitch". Professor McGonagall cannot turn into a cat like her book counterpart, but is still a powerful and formidable witch and even possesses a flying machine, which she uses at the end of the musical.
Professor McGonagall threatens to expel Harry, Ron, Hermione and Ginny when she finds them in the destroyed Greenhouse, where they have destroyed a crop of Mandrakes and killed Professor Sprout when they fly their enchanted car to Hogwarts. However, Draco Malfoy quickly provides an alibi for them.
After Hannah About is petrified, Professor McGonagall announces that the school will have to be closed unless the Chamber of Secrets is found and the Basilisk killed but is later moved by her students desire to keep the school open and uses her flying machine to buy them some time.
In A Very Potter Musical, Harry claims that all of the professors are dead so it is possible that Professor McGonagall either survived the Battle of Hogwarts or wasn't employed at Hogwarts until after Voldemort's demise.
