25 TV Villains Who Give Us Nightmares

Anyone who gives a name to a barbed-wire covered bat is the stuff of nightmares. Eenie-Meanie-Miney-Mo will never sound so innocent again.

The evil only exists in your mind...or does it? It's a scary thought knowing that something only you can see can torture you until you give in to its evil, but that's exactly what The Salesman is doing to Casey Rance. Shudder!

Imagine a being like this so close you could almost touch it, but who would want to? The Monster or demogorgon lives in another dimension called the Upside Down, but was able to enter our world through tears in the fabric of reality. It was attracted to the smell of blood and would cpature victims and bring them back to its world, sometimes killing them, sometimes not! Let's hope there are no tears in the fabric of our reality!

Hypnotism is scary under normal circumstances. Who knows what happens when you're put under? But, imagine if it was a madman doing the deed? Oh, my! Time to run!!

Sidney just looks like evil incarnate, yet many people in Rome are welcoming him into their lives. Probably not a good idea, but that's exactly what the man-in-charge of demons or whatever they are wants. So, beware of the new guy in town. Never know who he might be.

Vampires are some of the scariest beings, but imagine being running into one of the original vampires? Even worse? Getting infected by a virus that automatically turns you into a vampire and not even knowing what happened. It's the stuff of nightmares!
