9 Scariest Horror Movie Monsters (4 of 5)

Graboids—Tremors (1990)

If sharks lived underground and had long, creepy tongues, they’d be called Graboids. These creatures hear everything from your footsteps to a falling rock somewhere on the other side of town. They snatch trucks, juicy cattle, and anyone who assumes “solid ground” is safer than ocean depths. Their secret weapon is patience. They will strategically conceal themselves and wait for the right moment to submerge you into the earth. The only advantage they have is their inability to dig through solid rock and their allergy to high-caliber, point-blank rounds.

The Babadook—The Babadook (2014)

Who’s got a top hat, too many Tic Tac teeth, and a pop-up book that feels more like a threat than a story for kids? This guy! The Babadook possesses people not to conquer but to collapse them inward until they’re saying things they’d never say in their life. You don’t kill it; you manage it, which is somehow scarier and more difficult.
