5. Minerva Mcgonagall
An extremely talented and skilled witch, teacher and leader, McGonagall defended Hogwarts and its students admirably in the Final Battle, getting her opportunity to take on Snape finally. Not only is she extremely kind-heartened, which is a type of magic in itself in Rowling's world, she also took on four stunning spells to the chest, which should have blown her away but she fully recovered and became the headmaster of Hogwarts. Not only is she a badass Animagus, she has got all kinds of Transfigurations down and even duelled against Voldemort alongside Shacklebolt and Slughorn without popping her clogs.
