They’re proof that if you’re having a bad day, it’s because the Macroverso decided to say “hi” to you.

We selected the 5 monsters that are not only visually terrifying, but that carry with them a load of existential horror e biological that makes Michael Myers look like a bored knife fan. Get ready to meet the top of the fear food chain.

5. Pennywise – It – The Thing (2017)

Why it’s terrifying: The list places it in fifth place, and we agree. Pennywise is more than just a scary clown. He is himself Fear Personified. He doesn’t need claws, because he uses his childhood trauma as a weapon.

Why it’s terrifying: The terror of Hellraiser it is purely existential and bodily. The Cenobites don’t want to kill you, they want you transform. They are the embodiment of pain so extreme that it becomes, for them, a kind of transcendent pleasure. To see Pinhead, with his head covered in nails and his face skinned, is to behold a distorted gothic beauty.

They torture you with formal etiquette that only increases the level of discomfort.

• Reproductive Invasion: O Facehugger violates your face to impregnate you with the Chestburster. It is a physical and sexual violation that leads to brutal (and inevitable) death.

• Almost Indestructible: He has acidic blood that melts the floor and walls of the ship, turning any attempt to kill him into an even greater threat to everyone.
