There Are Over 200 Harry Potter Characters — We'll Be Impressed If You Can Name 40!

At first, Harry thought Sirius Black was just another demented prisoner of Azkaban who escaped to kill him. But it turns out that Sirius and Harry's father go way back, and Sirius is, in fact, his godfather. Harry immediately feels a strong bond with him when he discovers this fact.

Hermione Granger is the bookish know-it-all student who's just interested in learning at her magic school. For someone who didn't grow up in a wizarding family, this is fairly understandable, since she can't get any information from her muggle parents who are both dentists.

Albus Dumbledore served as a very wise and benevolent headmaster, professor and mentor to Harry during his younger years. Outside of the original Potter book series, he is being given a "prequel" characterization in the newer "Fantastic Beasts" film series, where he is played by Jude Law.

Ron Weasley is Harry Potter's best friend throughout the series, though they also had their clashes every now and then. Ron ended up partnering with Hermione romantically, though there are write-ups that pointed out how he exhibited unhealthy behavior for a male partner in some scenes.

To be born half-muggle and half-wizard is just unacceptable for the ambitious young student named Tom Marvolo Riddle, who used his time at Hogwarts to prepare himself for a bigger plan later on: to become Lord Voldemort. As a Dark Lord, they referred to him as "He Who Must Not Be Named."

Hagrid is the endearing half-giant who first fetched Harry at Privet Drive so he could be taken to Hogwarts. Since then, he has acted like a protective older brother to Harry and to Harry's friends as well.

Draco Malfoy is identifiable as the "easy villain" in the early Harry Potter books; he made fun of non-rich people like Ron, openly showed his disgust at muggle-borns like Hermione, and bullied Harry to no end. But when he matured, he also experienced conflicted thoughts about being purely evil.

Professor McGonagall was first introduced to us in the form of a cat, which is a good introduction to her skills as a Transfiguration teacher. While she is protective of her Gryffindor House students, she also doesn't let them slip when they commit errors or break school rules.

With a name like Luna Lovegood, it's hard to miss her presence, especially since her fashion sense is also quite "unique," so to speak. A member of the Ravenclaw House, she's a talented and creative person, and is a good representation of the unconventional teen character in the series.

Remus Lupin was the professor who taught Harry how to manage his exposure with the Dementors, and he struggled with managing his werewolf side while teaching. He was friends with Harry's dad, James, and Harry's godfather, Sirius.

Ginny Weasley is the only daughter in the Weasley family, and is also the youngest child. That's why older brother Ron was a bit overprotective of her when she started dating and kissing guys. It's also amusing to see that she ended up marrying Ron's best friend, Harry, after all that.

Throughout the book series, it's easy to distrust Snape, since he appeared to be the strictest and most vengeful professor of them all. But as his story unfolded, we saw that his character had depth, and his actions were prompted not by hate, but by love, specifically his secret love for Harry's mom.

It's hard to be a kid and carry misinformation about your parents as you grow up. This was Neville's lot early in his Hogwarts life, as people simplistically dismissed his parents as crazy folks. It was later revealed that they were fighting evil and were defeated as part of the Order of the Phoenix.

Dudley Dursley was Harry's first cousin, since their mothers are sisters. This character was used as a contrasting figure to see how the Dursleys treated the two teen boys differently under one roof, especially when they learned that Harry was a wizard, too, just like his mother.

If you're wondering why Fred Weasley, twin brother of George Weasley, is full of antics, that's because they were born on April Fool's Day. The twins were the ones who gave Harry the Marauder's Map, an important tool they later used not only for pranks, but to escape trouble.

Professor Trelawny taught Divination class, which teaches students how to see into the future through the use of objects like tea leaves and crystal balls. Since it doesn't appear as an "exact science" in the magical sense, Professor Trelawny often received flak for her teaching and her seer talent.

In the wizarding world, house-elves are non-human creatures capable of doing magic, too. But since they are enslaved, they can't do anything outside of the command of their masters. This was the lot of Dobby the house-elf, the Malfoys' slave, before Harry maneuvered his freedom.

Gilderoy Lockhart appears as a good-looking and charming fellow who can attract women just by flashing them a smile. In reality, his charm is as false as his authored books' claims of defeating dark creatures, for he stole those stories from other wizards and used them to garner fame.

Rita Skeeter is a magical being who tries to be present in many events, even if she is not welcome there. That's because she is a reporter for the Daily Prophet, but her journalistic practices border on tabloid-style sensationalism.

A proud Death Eater, Bellatrix Lestrange is one of the most devoted servants and allies of Lord Voldemort. She is revealed as the first cousin of Sirius Black and the aunt of Draco Malfoy, since Draco's mother is Narcissa Black. Her maiden name was Bellatrix Black,and she married Rodolphus Lestrange.

Moaning Myrtle was a Ravenclaw student who died inside a girl's bathroom, which is why she ended up haunting that particular place. She came face to face with the Basilisk there, which caused her death. Harry and his friends discovered this when they were trying to find ways to defeat the basilisk.

The Bulgarian student athlete Viktor Krum is from the Durmstrang Institute for Magical Learning, and he was the school's representative in the Triwizard Tournament. But he is also a national Quidditch player, which is why he was internationally famous prior to the inter-school tournament.

Before playing the book-to-film character of Edward Cullen in the "Twilight" series, Robert Pattinson played the book-to-film character of Cedric Diggory, whose storyline was prominent in "The Goblet of Fire" book. He was supposed to be the lone Hogwarts representative at the Triwizard Tournament.

One of the most prominent Ravenclaw students was Cho Chang, mainly because Harry took a liking to her. It was clear that Harry had a huge crush on her, and it was also hinted at that she harbored the same secret feelings for him. He asked her to the Yule Ball, but Cedric had already beat him to it.

Dolores Umbridge was working at the Ministry of Magic when she was called upon to teach Defence Against the Dark Arts at Hogwarts as a part of closely monitoring anti-Voldemort goings-on in the school. She later took over the leadership of the school prior to Voldemort's planned attack.

French magical students went to Beauxbatons Academy, and Fleur Delacour was their school's representative in the Triwizard Tournament. She ended up getting engaged to Bill Weasley, and they later got married before the major events in "The Deathly Hallows" happened.

Nymphadora Tonks, or simply known as "Tonks," is the young Auror who trained under Mad-Eye Moody. One prominent aspect of hers, as elaborated in the books, was her ability to change the color of her hair whenever she pleased, but this wasn't explored much in the film series.

Lucius Malfoy is the conniving Death Eater who uses his wealth and connections to get ahead in the wizarding world. He helped Voldemort slowly get back to life by running "small" errands that were actually big steps in the dark lord's return, such as letting Ginny Weasley "have" Tom Riddle's diary.

Mad-Eye Moody was requested by his friend Albus Dumbledore to go back to teaching in Hogwarts. But before getting there, he was imprisoned by a Death Eater, Barty Crouch Jr., who impersonated him to gain access inside Hogwarts.

Madame Olympe Maxime came to Hogwarts for the Triwizard Tournament because she serves as Beauxbatons Academy of Magic headmistress. She appears to be as tall as Hagrid, who took a liking to her, since they are both half-giants. But nothing really happened with this attraction.

In the books, Nagini is one of Voldemort's horcruxes, the last one to be eradicated, leaving Voldemort vulnerable enough to be killed. Nagini's origins is being unraveled in the newer "Fantastic Beasts" movies to show how she ended up as a snake serving Voldemort.

For high quality wands, wizards flock to Ollivanders in Diagon Alley to purchase one. The store is run by Garrick Ollivander, the wand expert in the wizarding world. He was the one who also told Harry about the famed Elder Wand which Voldemort was looking for in "The Deathly Hallows."

Argus Filch is the scary-looking caretaker of Hogwarts, and he is always on the prowl to catch students playing hooky. In the books, he is revealed to be a squib, or those children whose parents both have magical abilities, but they don't have any magical capability at all.

Padma Patil from Ravenclaw House was Ron's Yule Ball date while her twin sister Parvati went as Harry's date after he was rejected by Cho Chang. Both the Patil twins joined Harry later on as part of Dumbledore's Army, the students doing extra training to prepare for Voldemort's pending return.

Professor Slughorn is the Potions teacher who came back to Hogwarts, but Dumbledore had a secret agenda as to why he asked the retired professor to teach again. Slughorn was the one who introduced the concept of the horcrux to young Tom Riddle, and Dumbledore asked Harry to find out more about it.

Vincent Crabbe is one of young Draco Malfoy's henchman, if you will, along with another Slytherin stooge named Gregory Goyle. But their bravado only lasts for as long as Draco's, so when his falters, theirs also dissipates, like that time Hermione punched Draco in the face.

Rowena Ravenclaw possessed a diadem which her daughter, Helena, stole from her and hid in a foreign land before dying. Helena's ghost is Ravenclaw's house ghost, and Harry talked to her to get more information on where it is, and how it turned into one of Voldemort's horcruxes.

The former friend of Sirius Black, Remus Lupin and James Potter during their Hogwarts years, Peter Pettigrew became a Voldemort Death Eater during his adulthood. He framed Sirius Black for the death of Harry's parents, which led Sirius to being imprisoned in Azkaban. He hid as Scabbers, Ron's rat.

Petunia Dursley is indeed the only living relative of Harry; that's why Dumbledore left him with her as a baby. Petunia and Harry's mom, Lily, were sisters, but Petunia didn't see Lily's magical abilities as a special gift.
