McGonagall is a professor at Hogwarts School of Witchcraft and Wizardry, where she is also the head of Gryffindor House and the deputy headmistress under Albus Dumbledore.

After noticing Harry's broomstick flying skills, McGonagall introduces him to the Gryffindor Quidditch team captain Oliver Wood.

At the beginning of Harry Potter and the Prisoner of Azkaban (1999), McGonagall gives Hermione Granger a Time-Turner to allow her to take multiple classes at the same time.

After the Ministry-appointed Defence Against the Dark Arts professor Dolores Umbridge refuses to teach students practical defensive magic, McGonagall supports Harry, Ron and Hermione as they form the self-defence group Dumbledore's Army.

In Harry Potter and the Half-Blood Prince (2005), McGonagall duels with the Death Eater Alecto Carrow during the Battle of the Astronomy Tower.

Several websites have pointed out that according to timeline details provided in Order of the Phoenix, McGonagall would not have been teaching at Hogwarts during the events of these films.

[citation needed] The entertainment website IGN wrote that McGonagall is usually "a strict disciplinarian" but can also be a "cool aunt" who occasionally allows mischief.

[10] WatchMojo published a video which ranked McGonagall as the 9th best Harry Potter character, describing her as a powerful, austere and imposing witch with "a strict sense of responsibility" but who also "has a softer side".
