    The Troll In The Dungeon
    Really not that bad, just used for the whims of other bad guys.
  2. 12.
    Lucius Malfoy
    Classy MOFO but pretty elitist.
  3. 11.
    Lord Voldemort
    I know he's the main bad guy but he's also one of the smartest and most powerful wizards ever. Just wanted to live forever, and maybe enslave/kill all the muggles but still.
  4. 10.
    Dudley Dursley
    Why is he so mean, anyway?
  5. 9.
    Petunia Dursley
    Really just jealous but takes it way too far.
  6. 8.
    Fake Mad-Eye Moody (Barty Crouch Jr.)
    Kidnapping and impersonating a professor, enabled the rise of Dark Lord and ushered in the death of Cedric Diggory and countless others.
  7. 7.
    Fenrir Greyback
    What kind of werewolf bites people even when he's not in werewolf form?
  8. 6.
    Creepy AF.
  9. 5.
    Diary Tom Riddle
    Manipulating an 11-year-old who just wants to share her feelings? Terrible and mean.
  10. 4.
    Bellatrix Lestrange
    Outrageously elitist and creepily in love with Voldemort.
  11. 3.
    Vernon Dursley
    Basically a fat British version of Donald Trump?
  12. 2.
    Peter Pettigrew
    Backstabbing weasel of a man.
  13. 1.
    Professor Umbridge
    The worst. She has a stupid smile and laugh and her evil narcissistic bitchiness is awful. I hate her. I hate her so much.
