Top 10 Most Evil Harry Potter Villains

She made students write lines with their blood! She tortured them for nothing and was so hard-headed! If you go onto Pottermore and read about her past, she'll seem even more terrible. She hated both her parents, bullied her coworkers, and prejudiced and hated Muggle-borns. She even lied about her heritage, claiming she was pure-blood when her mom was a Muggle and her brother was a Squib! She had power she could have used for good, but instead, she used it for her own wants. At least Voldemort waited until the end of the school year to try to kill Harry. She tortured him during his school year!

Sorry if I used bad grammar/spelling. I'm just so frustrated with this woman! I'm usually the grammar police, always using perfect grammar, good spelling, and interesting words.

Voldemort killed Harry's parents and his own parents. He and Harry fought many times until Deathly Hallows: Part 2, when Harry finally killed Voldemort. He enjoyed killing people. He killed Cedric Diggory, Severus Snape, and Fred Weasley. He made Severus Snape work for him for a long time and turned Snape into a bad guy, but Snape became good in the end. Voldemort made Severus Snape, Bellatrix Lestrange, and Lucius Malfoy all become Death Eaters. Voldemort was so powerful he was really hard to kill. He had strong magical powers that could not be easily defeated.

Bellatrix is the Harry Potter villain I hate most of all. Most people say Umbridge is the worst villain, but I disagree. Umbridge was only ever cruel. Bellatrix is a murderer and just as evil as Voldemort.

1. First of all, Bellatrix killed Sirius. I will never forgive her for that. Ever.
2. She killed Tonks (one of my favorite characters).
3. She killed Dobby.
4. She tortured Alice and Frank Longbottom to insanity.
5. She tortured Hermione.
6. She tried to kill Ginny.
7. She alienated her sister Andromeda just because Andromeda married a Muggle.
8. She's in love with Voldemort. Like... what?!

He deserves to be number one. He betrayed all of his friends, and because of it, Sirius and Lupin lost their friends. Peter is a spineless, no-good, evil, low-down, ratty little man who I want at the top of this list!

He betrayed his best friends by turning to the dark side. He is indirectly responsible for James' and Lily's deaths, and he helped Voldemort come back to power.

Peter was a Death Eater. His friends trusted him with their lives, and he went to the Dark Lord and revealed where they were hiding. He is the primary reason his "best friends" died.

Fenrir Greyback is a fearsome werewolf that attacks children at Hogwarts. He had a strong army to kill as many people as he could. He and his pack of werewolves joined Voldemort during the Second Wizarding War. He fought in the Battle of the Astronomy Tower and became a very powerful werewolf, frightening many children at Hogwarts.

He transforms young kids into werewolves and loves the taste. He transformed Lupin, which I hate, and he kills for fun even when he's not a werewolf.

Quirrell brought Voldemort back to life so he could kill Harry for good. He made Voldemort powerful and a tough opponent. He decided to resurrect Voldemort just because he didn't like Harry in his class, and he liked that Voldemort killed his parents. He worked for Voldemort even though he thought Voldemort was dead.

He was a villain. The Weasley twins threw snowballs at his turban at Christmas, hitting Voldemort with snowballs. But I doubt Quirrell was anti-Muggle. He taught Muggle Studies before Defense Against the Dark Arts.

Barty Crouch Jr. was a worker for Voldemort, but he didn't last long. He tried to kill Harry, Hermione, and Ron until his father, Barty Crouch, told him not to. Instead, he killed his own father, even though he only lasted for five or ten minutes in the movie.

Voldemort said he was his most loyal servant. He helped Voldemort come back to power and put Harry's name in the Goblet of Fire. He also killed his own father and participated in the torture of Frank and Alice Longbottom.

A very slippery man, he was a big coward. He slipped the diary into Ginny Weasley's cauldron and caused the Chamber of Secrets to be opened. He was also very mean to his house-elf, Dobby, and was one of Voldemort's most loyal supporters.

In the end, Lucius may be weak, but he didn't just jump into action. He tried to remain calm, and a calm villain is better than one who yells at everyone. Also, he put a diary into another book without anyone noticing. He actually got the prophecy, though it broke shortly after.

Giant, ugly snake who can kill you with one look directly in the eye.

I know he is not really in the Harry Potter books except for a small part in the seventh and a mention in the first on Dumbledore's chocolate frog card. However, he is the second most evil wizard in the universe, only after Voldemort.

He was an ex-Death Eater, yet he never seemed to care about Harry, only about his mother. He probably would've stayed a Death Eater if he hadn't supposedly loved Lily Potter. He couldn't be nice to Harry, even though he loved Lily, because he still held a grudge against James.

I read he was based on J.K. Rowling's chemistry teacher. The chemistry teacher probably had the cane and threw the blackboard duster at them. Kids were just unlucky back then, probably making Severus Snape in the book a nasty teacher.

He was only mean out of jealousy. His father was very successful, and maybe Draco just wanted to make him proud. However, Harry Potter always got the attention. He was taught from an early age that he was better than everyone else. His dad was horrible, but Draco was just under a terrible influence.

In the end, we saw he didn't really have the heart to kill anyone. We realized he was human too, facing things no 16-year-old should ever face in his life. Murder or be murdered. Draco Malfoy would have been better if only his parents were better.

The Dursleys were so mean and terrible to Harry. They only cared about their own son and themselves, never about anyone else, including Harry. Vernon and Petunia taught their son Dudley how to be horrible to Harry, who was Dudley's cousin. Harry had to live with his aunt and uncle after his parents died when he was a baby. The Dursleys did not treat Harry right or take care of him at all. They made a terrible rule that he could not have food for a week, which was really horrible.

It's a snake. Snakes are evil animals, but Nagini is probably a good (person?) snake. However, she's possessed by Voldemort.

More like a spoiled brat. Who gives a kid 36 presents for their birthday? He was a bully but was never punished by his parents, which was wrong. His mum was ignorant and saw him as an angel, and his dad egged him on.

When he saw how horrible he was during the Dementor attack, he didn't really say anything. In the sixth book, he made Harry a cup of tea and thought Harry was coming with him and his parents when they had to leave their home for protection.

She wrote so many lies about everybody. I wish one day Hermione would put a magnifying glass on her and burn her alive.
