A killer barber who serves his victims in meat pies, and sings about it. That, my friends, is entertainment.
6. The Trashcan Man from Stephen King's The Stand
Trash is a bedwetter and a pyronmaniac. He's also an object lesson for bullies about what happens when the worm turns, which makes him an oddly sympathetic character.
5. Hannibal Lecter

Chilling in book form, Anthony Hopkins and Jonathan Demme combine to make the good doctor out and out terrifying onscreen. This is what it looks like when the smartest man in the world has no conscience (and a taste for long pig).
4. W.H. Donovan from Donovan's Brain

Millionaire W.H. Donovan is so evil that his disembodied brain is capable of wreaking havoc after his demise. Sure, you can watch the 1953 movie.
But for a real treat, check out Curt Siodmak's novel.
3. Dr. Fu Manchu
Fu hangs out in the hot tub while his boy Shang-Chi is one of the Uncanny Un-Collectibles.
"Imagine a person, tall, lean and feline, high-shouldered, with a brow like Shakespeare and a face like Satan, . . . one giant intellect, with all the resources of science past and present . . . Imagine that awful being, and you have a mental picture of Dr. Fu-Manchu, the yellow peril incarnate in one man.” –The Insidious Dr. Fu Manchu
2. Dr. Phibes from The Abominable Dr. Phibes

A musician loses his beloved wife in a car crash and determines to take revenge on the nine doctors who saved his life and didn't save hers. Vincent Price goes positively biblical on their behinds.

The baddest mama's boy since Oedipus.
