What is a Dementor?

 Dementors are among the foulest creatures that walk this earth. They infest the darkest, filthiest places, they glory in decay and despair, they drain peace, hope and happiness out of the air around them. ... Get too near a Dementor and every good feeling, every happy memory, will be sucked out of you.

The wizarding world has giants and dragons and spiders which are big enough to drive a car – and none of these even come close to the chills brought on by the Dementors of Azkaban.

The Dementors win the award for Most Loathsome Creatures Ever because Voldemort sees them as his natural allies and he’s right. Any creature that thinks he is the one to watch, is one to, well, watch. A fact that Cornelius Fudge forgot at great cost.
