Headmaster of Hogwarts throughout most of the Harry Potter series, it is safe to say that Dumbledore is the most powerful professor at Hogwarts. With his Elder wand, Dumbledore managed to get away both times he was threatened imprisonment at Azkaban. He could also duel Voldemort and hold his ground.
For example, in Harry Potter and the Deathly Hallows – Part 2, Snape was reluctant to fight McGonagall when the latter took him to a duel in front of Hogwarts students. Both characters had their strengths, but the last Harry Potter movie proved Snape was the strongest Hogwarts professor.
Okay, sure, Minerva McGonagall was often strict and very much adopted a "tough love" policy with her students, even if they're part of her own house.
Defense Against the Dark Arts: Minerva was exceptionally experienced and accomplished in defensive magic as she fought in the two wizarding wars and survived, having defeated powerful dark wizards and witches in process and even surviving a duel with Voldemort himself.
Albus Percival Wulfric Brian Dumbledore was the only wizard Voldemort ever feared and the only one who could have defeated him in a duel. Albus Dumbledore is the most powerful wizard in the Harry Potter.
In the Harry Potter series, had Minerva McGonagall and Severus Snape both gone all out in a duel, who would have won? Severus Snape would win hands down, as evidenced by the clash of the seventh book or the eighth film.
Riddle is 9 years OLDER than McGonagall.
She was strong enough to kill Tonks (an auror). McGonagall had no such lack of discipline and was incredibly powerful in her own right. Bella was the only death eater that was able to deflect one of the spells from Dumbledore.
Professor Severus Snape was Harry's least favorite teacher. Harry also happened to be Snape's least favorite student.
Teaching career at Hogwarts
Slughorn during the time he taught Tom Riddle. After completing his education, Slughorn was made Potions Master, by Hogwarts School of Witchcraft and Wizardry, at the same time as Albus Dumbledore started.
Phineas Nigellus Black, who to this day remains the least popular headmaster Hogwarts has ever known, makes little effort to hide the utter disdain he has for his students. He is a cantankerous, lazy and vain pure-blood with a myopic view of the world and a condescending and unjustifiably superior attitude.
Weaknesses. McGonagall is never portrayed as having any particular weaknesses. Her stern facade likely prevents anyone from getting close to her emotionally, with the possible exception of Dumbledore. We are led to believe that she prefers her solitude.
Winner: Snape
The kind of versatility in magical abilities that Snape displayed was almost around the level of Albus Dumbledore and Voldemort, making him easily more powerful than the average wizard and even the members of the Order of the Phoenix and the Death Eaters.
Minerva McGonagall
McGonagall was among the oldest and most experienced teachers in Hogwarts, and she was a worthy successor to Dumbledore as the headmistress. In fact, she has proven her mettle against Voldemort and survived a duel against him.
Later in the year, McGonagall duelled with Death Eater Alecto Carrow during the Battle in the Astronomy Tower and later learned of Snape's murder of Dumbledore. McGonagall was initially appointed as Headmistress, but was demoted after Voldemort took control of the school and placed Snape as Headmaster.
She Screams When Harry 'Dies'
And this tips Minerva over the edge, with the Transfiguration teacher letting out a horrendous scream that pierces the air. Harry is actually alive, of course, but he's shocked that McGonagall could make such a noise.
This would possibly the character of McGonagall over 100 years old around the time of the Harry Potter books. The official online resource for Harry Potter, WizardingWorld.com, confirms this discrepancy, listing McGonagall's date of birth as 4 October 1935.
Outnumbered, Snape dashes into a deserted classroom where a loud crash is heard. Pursuing, McGonagall screams, "Coward!" Uncloaked, Harry and Luna rush inside, startling the other professors. Snape has leaped out the window.
Originally Answered: How did Umbridge and other ministry members mange to get away with attacking Professor McGonagall in book 5? As Minister of Magic, Fudge was adamant to believe that Voldemort had returned.
Now, as firmly established, Snape was not the greatest fan of Harry, but that didn't mean that he ever stopped loving Lily. Dumbledore was surprised that Snape seemed to care for the boy. With a swish of his wand, Snape conjured up a Patronus – Lily's Patronus, a doe. 'Always,' he said.
Slytherin house has some trouble with shaking its murky reputation – and it's all thanks to a certain few witches and wizards like Lucius Malfoy. Today we look at the reasons why he embodied all the worst Slytherin traits and gave his house a bad name… Lucius Malfoy was an odious character.
Belonging to the Black family, Phineas is one of Slytherin's loveliest members. Taking a greater moral standpoint than his other family members, who mostly believe in pure-blood supremacy, this good-natured wizard has shown himself to be an especially well-behaved member of the otherwise unruly Hogwarts house.
