Hermione Granger Perhaps Hermione would have had some trouble against Voldemort in her early years, but as an adult witch, she could certainly give him a run for his money if not outright demolish the Dark Lord. Her power combined with her breadth of knowledge is tough to beat.
Hermione's capacity for and relentless pursuit of knowledge makes her one of the most powerful characters in the Harry Potter universe. Of course, she doesn't look it, but there are plenty of times when she demonstrates this throughout both the books and the movies.
Hermione could beat Dumbledore any day if she wanted to. She's one of the most brilliant minds of her generation; like any good Gryffindor, she's brave, loyal, and strong. She mastered advanced spells at a young age, could make any potion perfectly, and her quick thinking saved her, Ron, and Harry more than once.
Hermione: Better At Everything Else
Harry achieves a higher mark in their Defense Against The Dark Arts O.W.L., but Hermione grades higher in every other lesson. This includes Charms, Potions, and Transfiguration, all complicated methods of magic capable of overwhelming Harry's defensive skills.
He wasn't attacking her, simply was reflecting her spells. In the 7th book, she duelled him together with Kingsley Shacklebolt and Horace Slughorn, and they were unable to finish him, so no, she could not have won alone.
He also divided his soul into seven Horcruxes to make himself immortal. 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.
Harry's other best friend, the bookish and kind Hermione Granger can't be beaten in the classroom. Harry recognizes her as his year's best student and even said so at some point. But while Hermione can ace any test, she can't quite keep up with Harry on the battlefield.
Hermione was good at defensive spells and charms, but she was once caught and hurt by Bellatrix, which should be enough to suggest she couldn't defeat the evil witch in a duel.
Even though Hermione is the brightest witch of her age, Bellatrix far outclasses her in terms of magic, may it be duelling skills or knowledge of the Dark Arts. If Hermione wanted to duel Bellatrix, then she should at least practice the Unforgiveables, most importantly Avada Kedavra.
In each installment of the Harry Potter series, Hermione Granger is the smartest of the trio. She has the best academic memory, highest grades, and always expanding her knowledge. However, it is Hermione's logic and by-the-book mentality that allows Harry to surpass her.
Hermione Granger
Beyond just being studious, she was able to perform extremely advanced magic, like brewing the Polyjuice Potion as a second-year or the combination Protean Charm/jinx on Dumbledore's Army's coins that permanently disfigured classmate, Marietta Edgecombe.
In Harry Potter and the Sorcerer's Stone, Hermione discounts her power as simply “books and cleverness,” but by the end of the series she proves through her sacrifices, empathy, and love that she is just as “great” a witch as Harry is a wizard — if not greater.
Ginny is the youngest in the Weasley family but one would argue that she is the most powerful. The movies show a little bit of it but in the books, she can throw some pretty powerful spells right alongside Hermione, who happens to be one of her closest friends. You want power in a little package… look no further.
The most prominent Muggle-born in the Harry Potter series is Hermione Granger, who was born to Muggles of undisclosed names. Witches and wizards with all-magical heritage are called pure bloods.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Cruciatus Curse ('Crucio')
Harry tried to use this spell himself. The first time was against Bellatrix after she had killed Sirius. His attempt was unsuccessful because, as Bellatrix mockingly explained: 'You need to really want to cause pain – to enjoy it – righteous anger won't hurt me for long…'
In Deathly Hallows, Hermione faced a real test of her physical and psychological stamina. After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse.
After Molly cast a well-aimed lethal spell at Bellatrix, she toppled lifeless to the ground, making Voldemort scream in fury and point his wand at her. Harry Potter cast a Shield Charm between the two of them, thus revealing himself and setting the stage for the duel that ended the Second Wizarding War.
Weakness: Sometimes she was close-minded
For all of Hermione's many strengths, one of her biggest weaknesses was that she could be close-minded. She often thought her way of viewing the world was the only right one, and she would shut down anything that seemed illogical to her.
In fact, without Hermione Granger, maybe there wouldn't even be a Harry Potter series at all; Harry and Ron would have probably died tangled up in some Devil's Snare in their first year. Thankfully, Harry happened to make best friends with the smartest, most dexterous and logical witch of his year.
The Rowling Library on Twitter: "Without Hermione, Harry would have died in book one.
