The Wizarding World is home to many powerful witches and wizards. The Harry Potter series focused on how one of the strongest wizards of all time, Lord Voldemort, was defeated by a simple rebound curse at the hands of an infant. The series deals a lot with power and how that can change and drive so many people.
As such, we see the world through the eyes of Harry Potter and meet many powerful characters along the way. Not only are there strong people to help him on his quest to defeat the Dark Lord, but we watch as Harry and his friends grow into capable wizards in their own right.
With new chapters in the Fantastic Beasts series introducing us to new powerful wizards, it seems that the Wizarding World is only going to get bigger and more dangerous from here. Characters like Dumbledore, Grindelwald, Harry Potter, and Voldemort all exist in the same universe, but who among them is the most powerful? Which of these characters would defeat all the rest in a duel?
Looking at the world of Harry Potter, we're taking 25 of its main characters and ranking them to see who is the most powerful wizard in the world (we are not including them after the 19-year time gap. They will only be accounted for through the events of The Deathly Hallows). For this list, we are including characters from the Fantastic Beasts movies as well with how closely they seem to be connected to the events of Harry Potter.
Hagrid is one of the most lovable characters in Harry Potter. He is the first real wizard Harry meets and remains a great friend throughout the entire series. Despite his big size, Hagrid is just a teddy bear. We don't see him perform that many spells, preferring more to take care of his own creatures. With his rocky experience at Hogwarts as a student, it stands to reason that he isn't quite as capable with spells as many other wizards.
Draco Malfoy is the antithesis to everything Harry Potter stands for. He's racist, selfish, and wants nothing more than to see Hogwarts destroyed. Despite his arrogance and attitude, Malfoy isn't that much of an impressive wizard. Sure, he's managed to get a few good hits in on Harry, but he's just an overconfident wimp. He was easily defeated by Harry and his friends in The Deathly Hallows and took a punch from Hermione in The Prisoner of Azkaban. He also lost a duel to Harry in The Half-Blood Prince.
The Weasleys might be seen as "blood traitors," but that never stopped them from fighting the good fight. As the youngest of the family, Ginny Weasley is probably the weakest, but that doesn't mean she can't hold her own in battle. Ginny has proven capable against Death Eaters in both The Order of the Phoenix and The Deathly Hallows, even going up against Bellatrix Lestrange. However, with her finishing the series having only been through her fifth year at Hogwarts, there was still a lot of spells for her to learn.
Luna Lovegood might not be the strongest witch of all time, but psychologically, she is made of iron. Turning all the despair in her life into her strength, Luna is one of the most interesting and inspiring characters. Her willingness to embrace stranger ideas makes her spells a bit more creative, and her experience at Hogwarts taught her well in that department. Some of her ideas alone were enough to help save the day more than once. She also fought against Death Eaters twice and survived.
While he started his time as a Hogwarts student as a clumsy kid who didn't know how to do anything, Neville Longbottom slowly grew into a confident wizard who always stood for what was right. His drive alone was enough to get him through serious battles, and he was the one who managed to end Nagini, leaving Voldemort at his most vulnerable. After his days as a student, Neville would later become the headmaster of Hogwarts, working in the footsteps of Dumbledore himself.
Queenie Goldstein is the sister of Tina Goldstein, who appeared in the Fantastic Beasts series. She was known for falling in love with a Muggle and teaming up with Grindelwald at the end of the second film. Her notable skills include the ability to read the minds of others. She seems to be a decent witch but her carefree attitude and big heart paint her in a more passive light. She doesn't seem exceptional in more traditional spells, which makes her much different from her sister.
Draco Malfoy might've been a bad guy, but he never compared to his father, Lucius. Lucius Malfoy had always been a supporter of Voldemort, having a serious disposition against Muggles and their effects on the Wizarding World. His time at the Dark Lord's side did teach him how to use some impressive spells, but he was never painted as a particularly strong character. He found himself defeated by other wizards time and time again before eventually leaving Voldemort at the battle of Hogwarts.
Voldemort's most loyal Death Eater, Bellatrix Lestrange was as crazy as her name implies. She reveled in the pain of others, always eager to enact the Dark Lord's will and take lives whenever she wanted. Her insane demeanor gave her a chaotic method of attacking, jumping around and luring opponents to only slay them once and for all. She twisted Neville Longbottom's parents to drive them to insanity and was responsible for the demise of Sirius Black after getting a cheap death curse on him.
Fred and George Weasley were the lovable twins in the Weasley family. Having a knack for getting into trouble, they would go on to start their own store where they sold comedic knick-knacks. They would often use their magical abilities for stirring trouble rather than downright fighting, which gave them a lack of experience. In The Deathly Hallows, both brothers suffered some sort of injury, with George losing an ear and Fred losing his life to a Death Eater. Seeing the Weasley family take such a blow was always heartbreaking.
While perhaps the least skilled of his friends, Ron Weasley was no slouch. By the time we reached The Deathly Hallows, he brought a lot to the table. He was able to defeat some Snatchers, helped take down the Malfoy family, and even opened the Chamber of Secrets. Ron was always more of a comedic relief character, but he always knew when to rise to the occasion. During the escorting of Harry Potter, he took on multiple Death Eaters and defeated most of them, with Tonks regarding that she wouldn't have been alive if it weren't for him.
Perhaps the worst headmaster to ever make it to Hogwarts was Dolores Umbridge. A corrupt official planted by the Ministry of Magic, Umbridge had all sorts of horrible ideas and strategies for discipline. She tried to suppress the knowledge that Voldemort had returned but paid the price for her actions. Harry and his friends managed to outpace her. She knew a good amount of spells, but her proper attitude prevented her from being a serious threat. In The Deathly Hallows, she was stunned by Harry, and the Horcrux she wore was taken right off her neck.
Harry Potter was the Boy Who Lived. Growing up, he learned of his destiny to fight the Dark Lord, but he also had to give his own life in the process. He was an excellent flyer and great at combat against all sorts of dark wizards and creatures. Above all, it was his courage that made him such a serious threat. Wizards and witches rallied behind him at every chance and worked with him to defeat Voldemort. He also had a knack for certain spells, like the Patronus Charm and the disarming spell.
Tina Goldstein is the female lead of the Fantastic Beasts series. An Auror for the Ministry of Magic, it is her job to find dark wizards and stop them. She has knowledge of many different spells and can handle herself in a fight. However, she was shown to be way out of her league when going up against Grindelwald, as were many of the other wizards of the time. Still, her determination for bringing evil magical people to justice has made her into a capable witch.
Remus Lupin was the wizard who became a werewolf. Despite his condition hindering him at times, Lupin was a powerful and confident wizard. He knew how to go against the dark forces of the world and was always willing to look danger in the eye. He was shown to take on Death Eaters with relative ease and was one of the people who created the Marauder's Map. Unfortunately, the sheer force and number of Voldemort's army would prove to be his ultimate undoing, and Harry would be the one to raise his son.
When it comes to Harry, Ron, and Hermione, it was always Hermione who had a solution for everything. Her love for magic and studying made her into one of the best witches who ever lived. She was gifted with all sorts of charms and potions, having all sorts of backup plans for any situation. She could wipe memories, cast magical shields, and even immobilize an entire room of pixies with ease. Without her help, Harry never would've gotten close to defeating Voldemort.
He was originally thought of as a criminal who gave away the location of Harry Potter's parents, but it turns out that Sirius Black was a noble wizard and a great friend of the Potters. He was Harry's godfather and, as such, had a lot of skill behind him. He was an animagus and could transform into a dog at will, but that worked alongside his exceptional spellcasting. He was an excellent fighter, quickly disarming Lucius Malfoy with ease. If only Bellatrix didn't get the drop on him with the "elimination" curse.
Newt Scamander is the protagonist of the Fantastic Beasts series and is a lot like Hagrid but with much more magical knowledge. What makes Newt so potent is that he manages to use cleverness to get out of each situation. That coupled with his impressive knowledge of magical creatures make him an awkward force to be reckoned with. Being an old student at Hogwarts, Newt has a mastery over several spells that we never even saw in the Harry Potter series.
Perhaps one of the strangest Aurors to date is Alastor "Mad-Eye" Moody. Having great experience looking danger in the eye (no pun intended), he was responsible for sending a great host of dark wizards to Azkaban. However, those days had an effect on his sanity, which led to his nickname. He has a lot of crazy methods, but he's never afraid to get down to business. The only reason he lost his life to Death Eaters was that he was greatly outnumbered and the person that was supposed to help him left like a coward.
Minerva McGonagall is one of the oldest professors at Hogwarts, but she packs a serious punch behind that caring voice and long hat. Not only is she an animagus, but she knows to perform spells that students would never dream of. When it was revealed that Snape was the one who ended Dumbledore, she let loose a host of fire from her wand just to try and avenge the old headmaster. It's likely that there are many more spells that she knew, but we never got the chance to see the extent of her abilities.
Easily the bravest man in the Harry Potter series, Severus Snape was a rollercoaster ride. It turns out that he was on Dumbledore's side the whole time and deceived Lord Voldemort from day one. As such, Snape was a powerful wizard, being both a master at potions and defense against the dark arts. There were all sorts of tricks and spells that he knew, but his greatest asset was his own mind. He tricked one of the most powerful wizards in history, and the only reason his secret was discovered was that he told Harry.
It's amazing to think that a creature designated as a slave was so powerful. House Elves, in general, are some of the most powerful creatures in the Wizarding World, and Dobby is no exception. Not only is he able to apparate in and out of places that are blocked from such magic, but he can also disarm and stun foes with just a snap of his fingers. If it weren't for him saving Harry and his friends at Malfoy Manor, it's likely that Voldemort would've won the war.
A boy tormented by grief and misery all his life, Credence Barebone became an extremely powerful magical creature. However, that seems to have all changed with the revelation that he is also a secret Dumbledore named Aurelius. The Crimes of Grindelwald ended with him shooting from his hand and putting a hole through the side of a mountain. It's clear that whatever he does next, Newt and his friends are going to have their skills put to the ultimate test.
Grindelwald was talked about in The Deathly Hallows as the twisted man who had the Elder Wand before Dumbledore. In Fantastic Beasts, we get to see just how strong a man he is. With the Elder Wand at his side, he can conjure spells that can take down armies of wizards at a time. It took an entire ring of wizards to stop one of his spells. What's worse is that it seems we've only seen the tip of his potential as the Fantastic Beasts series continues.
A wizard so dark and powerful that people dare not speak his name, Lord Voldemort was a scourge on the Wizarding World. Separating his soul into Horcruxes, he guaranteed that his first defeat would not be his last. He attacked the Wizarding World twice, gaining followers and destroying those who got in his way. Even without the Elder Wand, Voldemort did exceptional things that not even Grindelwald could hope to do. It took seven years to hunt down all his Horcruxes and destroy him forever.
If there was one wizard who could fight toe to toe against Lord Voldemort, it was Albus Dumbledore. The headmaster of Hogwarts was the one thing protecting Harry Potter from outside forces trying to destroy him in the school. Albus would later fight Voldemort and save Harry's life in the process. He was the one who dueled Grindelwald and won the fight, claiming the Elder Wand for himself. He only perished because he was cursed by a Horcrux, so he asked Snape to be the one to eliminate him. However, it was all because Dumbledore was playing the long game.
