Welcome to watchmojo and today we're counting down our picks for the most terrifying first appearances of horror's biggest villains.

Before we get started, this video will be full of plot details, so consider this your spoiler war.

A direct attack on the objectification of women, the substance holds nothing back.

Have you ever dreamt of a better version of yourself?

It is chock full of gross out imagery that can even turn the strongest of stomachs.

At the end of the film, the two leads, Elizabeth and Sue, finally become one.

Resulting in a globby flesh monster, AKA Monstro Lisa Su.

Like a Picasso painting coming to life, her body parts slip and slide all over the place.

With things like teeth burrowing in her chest.

The transformation is beyond jarring and ends in a grotesque blood soaked conclusion that is hard to forget.

This little terror might be sweet and innocent, but it could not be further from the truth.

Beneath Trick or Treat's Halloween mascot, Sam's burlap veil and cute onesie lie something very sinister.

During his own segment, Sam is unmasked by the cantankerous Mr.

Krieg, revealing a head that is half skull and half pumpkin.

It is a truly satisfying and chilling surprise that fits the tone of this underrated but beloved horror flick.

Always have candy ready for trick or treaters or you'll be in for a fright.

After seeing this movie, we're pretty sure that soup sales plummeted.

From a fungus to a to a ginormous, murderous, reptilian monstrosity, the relic's creature of the night is a sight to behold.

Known as the Kothoga, this mythical creature traveled all the way from South America to Chicago's Field Museum of Natural History.

Making the most of its extensive journey, it made sure to save all its scariest features for its big reveal.

Massive chompers and scaly skin make up this fearsome killer that all started from a bowl of cursed soup.

The mutated Bruin that terrorizes a group of scientists and soldiers in annihilation is downright terrifying.

With an exposed skull and spiked blood soaked teeth.

But that is not its most frightening feature.

Its growls actually replays and mimics the final screams of its victims.

When we finally see the fur covered beast, he first appears as a shadow, making his eventual reveal ripe with tension.

It's a slow and unhurried moment, leaving audiences begging for it to end as soon as possible.

Creepy woods ruled by a sinister ancient being.

Not exactly a selling point for a boys weekend.

In the ritual, a group of old friends head out on a hiking trip in honor of their late friend and all I can do is remember it.

Descending into a creepy Swedish forest should have been a red flag, but

they quickly learn that this holiday will be far from relaxing.

The pals are hunted by the child of Norse God Loki Modur, who is worshipped by a cult.

An elk like creature with no head is made up of craggy bones and antlers instead of limbs.

Its final horrifying reveal makes us wish this foursome had booked a cruise instead.

At the end of the Descent's first act, viewers get their first glimpse of the Crawlers, creepy subhumans who haunt the deepest caves in the Appalachian Mountains.

Have you seen anyone climb like that before?

I told you I saw someone that was not a human being.

When one of these slimy suckers pops up behind one of the characters, it is game over.

Sure, the Crawlers are pretty scary looking with their bat like features and man eating tendencies.

However, it is the spontaneity of its surprise appearance that really has us bolting out of our seats.

From the gaming systems to the big screen, this evil punisher is terrifying in any format.

In the 2006 movie adaptation of the video game, Silent Hill's Pyramid Head is arguably the scariest of all the villains in the series.

He's introduced by the uncomfortable sound of his massive blade being dragged on the ground before he starts slicing his way through a door fitted with a giant metal Tetrahedon helmet and an apron.

Pyramid Head opts for no shirt, revealing his muscular figure and intimidating and towering stature.

They're aggressive, they're uncontrollable, and there are literally thousands of them.

The infected from the 28 days later franchise are humans who are unfortunately contaminated by the ruthless Rage virus, bringing Britain to a standstill.

When protagonist Jim wakes Up in an abandoned hospital from an unrelated incident, he eventually roams into a church where he comes face to face with an infected priest.

His twitchy movements, unsettling snarls, and bloody eyes are pure terror.

The scariest part of the scene is that it's just a preview of what's to come.

It started as writing, and right from the beginning, you knew this was different.

Yep, this rental house is definitely getting a one star review list.

I don't know what the protocol is for this.

In Barbarian, Keith and Tess are booked at the same creepy house at the same time and discover something ungodly lurking in the basement.

Unfortunately, the former becomes the first victim of the Mother, an inbred mutant that clobbers him in a brutally violent fashion.

It is a particularly scary reveal because A, it comes out of nowhere, and

B, up until this point, we had no idea what scene sinister entity was haunting the worst Airbnb of all time.
