Can Dumbledore defeat Voldemort?
Dumbledore as we saw him could have defeated Voldemort. If he wasn't focused on protecting Harry and trying to expose him for the Ministry to see, he likely would have neutralized him for a while in the Ministry of Magic. He was too smooth with it.
He strongly dislikes Harry and often insults him by insulting his father James. As the series progresses, it is revealed that his treatment of Harry stems from Snape's bitter rivalry with James when they were in school together.
Harry doesn't have the same magical power as Voldemort but Voldemort didn't understand the power of having friends and true support along the way. Voldemort was the better wizard, but Harry was the better person.
Said to be one of "the four most brilliant witches and wizards of the time", Godric Gryffindor founded Hogwarts School of Witchcraft and Wizardry in his adulthood, with friends Salazar Slytherin, Helga Hufflepuff, and Rowena Ravenclaw, though he later severed ties with Slytherin.
Sirius was described as a powerful wizard by Minerva McGonagall, his former teacher. Sirius became an Animagus at only age fifteen, and was able to turn himself into a large black dog. As he is unregistered, he is able to take advantage of his ability to continually elude the Ministry of Magic.
Dobby. A house-elf who was utterly devoted to Harry Potter, Dobby put himself at great risk (and in serious physical pain) when he went out of his way to protect the young wizard from what Dobby knew would be significant danger.
In the Deathly Hallows, Grindewald refused to tell Voldemort the location of the Elder Wand. When Voldemort was taunted by Grindelwald telling him to kill him if he wanted because he would not reveal it, he killed Grindelwald with the Killing Curse.
Dark Arts: Though not a dark witch, Ginny could perform Dark Magic, at least moderately. She could create the Bat-Bogey Hex (which is what got her admitted into slug Club by Professor Slughorn) and performs the Reductor Curse quite well. Flying: Love: One of the strongest magic known to Wizard kind.
Canonly voldemort is more powerful than gellert grindelwald. Many fans who didn't read the books but claim they did and say that grindelwald was stated to be more powerful doesn't know what voldemort achieved.
Harry on the other hand is a DADA prodigy, able to learn advanced protective charms at a very young age. He is also physically stronger than Draco, being able to wrestle his wand from him at the Malfoy manor.
In 1943, Tom Riddle, the "Heir of Slytherin", opened the Chamber of Secrets to conduct a purge on Muggle-born students. This resulted in the death of Myrtle Warren, who eventually returned as a ghost. Riddle opened the Chamber again in 1993 through the use of one of his seven Horcruxes, his diary.
Hufflepuff is often considered the worst house at Hogwarts because it hasn't contributed as much to magic as other houses, except for a few exceptions like Newt Scamander. Hufflepuffs are known for their hard work but it rarely leads to major magical discoveries.
Being of age, Cedric submitted his name to the Goblet of Fire for the chance to become the Hogwarts Champion. On 31 October, the Goblet chose the champions to represent the three schools; Fleur Delacour for Beauxbatons, Viktor Krum for Durmstrang, and Cedric himself for Hogwarts.
Dumbledore easily. He beat Grindelwald *while* Grindelwald was using the elder wand. And even at the height of his power, Voldemort never openly attacked Hogwarts while Dumbledore was headmaster. He knew he'd be beat.
Could Dumbledore see through the Invisibility Cloak?
In a chat with fans on the-leaky-cauldron.org, J. K. Rowling answered a fan's question of why Albus Dumbledore was sometimes able to see Harry under the Cloak of Invisibility, explaining that he used the Human-presence-revealing spell with non-verbal magic.
In a straight-up 1v1 duel nobody would be able to defeat Voldemort except Dumbledore. He's just too powerful. Snape is probably the most powerful sorcerer besides those two and would put up a better fight against Voldemort than anyone else, but again Voldemort would just be far too powerful for him.
This event took place in the Shrieking Shack during the Battle of Hogwarts on 2 May 1998. During this event, Lord Voldemort murdered Severus Snape with Nagini, as he incorrectly believed Snape was the master of the Elder Wand.
He couldn't have cared less if James and Harry had ended up dead but couldn't stand the thought of Lily dying. While Dumbledore said he would protect the Potters, it was on the condition that Snape now worked for him as a double agent. Snape's love for Lily ran so deep that he agreed.
