9 Scariest Horror Movie Monsters (5 of 5)

Godzilla—Godzilla (1954)

I know what you’re thinking: “Really? A big lizard is supposed to scare me?” The fear isn’t just its size—it’s a walking thesis on nuclear trauma with its keloid-textured skin and “atomic” breath. He crawls from the sea carrying history like seaweed, reminding us that the real monster is humanity and our actions. Godzilla terrifies not merely by size but by origin, an ancient body shaped by our modern sins.

Xenomorphs & Facehuggers—Alien (1979-)

With Xenomorphs, every phase is worse than the previous one, but all of them are deadly. The Facehugger will kill the host if threatened. If you let it do its thing, the chestburster’s emergency exit will not be good for your body. And the adult form, with its slick, almost industrial design, acid blood, and a set of deadly weapons, will definitely finish off whoever’s left standing.
