Warning: Spoilers for 2021's Halloween Kills below!

A killer requiring no introduction, Halloween's Michael Myers is one of the most revered boogymen in horror movie history. Known for his eerie, expressionless mask and penchant for butcher knives, he's a frightening force to be reckoned with, and, with a body count in the hundreds—albeit spread across three separate timelines—he's got more than a few gruesome kills to his name.

From killing his own sister at the age of six to slaughtering an entire company of firemen in 2021's Halloween Kills, Michael Myers is seemingly unstoppable in his quest to hack up Haddonfield.

Judith Myers (Halloween)

A young Michael Myers in 1978's Halloween.

The slaying that started it all, Michael Myers began his murderous legacy at the age of six, killing his sister Judith with a knife stolen from the kitchen. Shown from an uncomfortable first-person perspective, the subsequent revelation that the killer was, in fact, a young boy must have come as a shock to audiences when the first Halloween premiered in 1978.

Though later entries in the franchise would attempt to explain it, Michael's motives remain fairly foggy, particularly in the new continuity. For many, the fact that his need to kill has no apparent meaning makes him all the scarier.

The Paramedics (Halloween 4: The Return of Michael Myers)

Michael Myers drives his thumb through a man's forehead in Halloween 4.

The opening sequence of Halloween 4 introduces audiences to a comatose Michael Myers who is being transferred from one hospital to another via ambulance. In transit, the paramedics attending to him let slip that he somehow still has a living relative, and it turns out to be a mistake they wouldn't live to regret.

Though he's apparently spent the last decade dormant, he remains remarkably spry. Michael springs into action, jabbing his thumb straight through a man's forehead before sending the ambulance careening off of the road. Myers then dispatches the rest of the attendants off-screen, and, face conveniently shrouded in bandages, he sets out on his second slasher spree.

Oscar (Halloween 2018)

After Allyson breaks up with her boyfriend, her shoulder-to-lean-on Oscar makes an unreciprocated advance. Then, left alone in someone's backyard, Oscar starts babbling to a neighbor about lost love, unaware that he's actually in the presence of Michael Myers.

Myers doesn't waste much time stabbing the teen and impaling him on a gate in one of the film's most tense moments. Oscar didn't have much of an influence over the film's direction, mostly serving as yet another body to add to Michael's kill count, but his particularly brutal death may have given some fans pause.

Janet (Halloween 2)

Janet's death in the 1981 horror movie Halloween 2.

Looking after a panicked Laurie Strode, night-shift nurse Janet seeks the aid of Dr. Mixter, only to discover that he's been killed via a syringe to the temple. She then promptly suffers the same fate at the hands of The Shape.

By 1981, films like Friday the 13th had made their mark on the horror movie landscape, ushering in an age of gratuitous violence. Halloween 2 was certainly part of that trend, turning Michael's kills into horrific spectacles. Watching someone be stabbed to death with a syringe would be uncomfortable from any angle, but, when it's seen from up-close, it's particularly galling, and this is easily one of the scariest scenes from the Halloween sequel.

The Firefighters (Halloween Kills)

A still from the firefighter massacre scene in Halloween Kills.

2021's Halloween Kills certainly lives up to its name, as Michale brutalizes his way through an entire company of firemen responding to the inferno Laurie Strode set in her own house in the final moments of the preceding film.

Shielding himself from the flames by hiding in Laurie's gun cabinet, Michael promptly bursts forward after the floor collapses on a fireman, sending him tumbling into the basement. Michael goes on to gore several firefighters with a pickaxe before slicing a man nearly in half with a circular saw.

Sarah (Halloween H20)

A still from Sarah's death scene in Halloween H20.

After she discovered her boyfriend's body in a dumbwaiter, Sarah is confronted by Myers, and she's forced to climb in with him and ascend to the second floor in order to escape. Myers is too quick, however, and calls the dumbwaiter back down before she can climb out, leading to one of her legs being snapped in half.

Michael then stabs her several times with his trademark butcher knife and leaves her corpse hanging in the pantry for the others to find. It's a cold-blooded kill, even for someone as emotionless as Michael Myers.

Officer Francis (Halloween 2018)

Michael Myers and a severed head from the new Halloween movies.

After rambling about Bánh Mi sandwiches in one of Halloween 2018's many intervals of comic relief, two police officers investigate an abandoned police car only to be attacked by Michael Myers. Though they're killed offscreen, their deaths remain some of the film's most memorable.

Despite an apparent eagerness to track down Laurie Strode, Myers took the time to convert one of the officer's heads into a human jack-o-lantern, a goring so ridiculous it verged on hilarity.

Laurie Strode (Halloween: Resurrection)

Laurie Strode's death in 2002's Halloween: Resurrection.

Easily the most reviled film in the Halloween franchise, 2002's Halloween: Resurrection featured more than a few questionable plot points, one of which was the death of longtime series protagonist Laurie Strode.

After Strode captures Michael on a rooftop, she moves in to remove his mask and determine his identity, but she comes too close and is grabbed. The two slide over the edge of the building, and Michael manages to stab Laurie. In an odd gesture, Strode kisses Michael and remakes that she'll see him in hell before plunging to her death.

Karen (Halloween 2)

Karen's death in the 1981 horror movie Halloween 2.

In typical horror movie fashion, the teens featured in Halloween 2 are a bit too preoccupied with physical intimacy, a mindset that leads to their untimely demise.

When Budd and Karen meet in the hospital's physical therapy hot tub for some alone time, Michael Myers arrives to turn up the heat—literally. After Budd hops out to investigate, Micheal kills him, and he then sneaks up on Karen and drowns her in the burning hot tub while simultaneously scalding her face off. Featuring a bizarre mix of brutality and nudity, this kill is one of Myer's most memorable.

Bob (Halloween)

A still of Bob and Michael Myers from the horror movie Halloween.

After heading downstairs for a beer and inexplicably opting against turning on any of the lights in the kitchen, Bob discovers the home's back door to be ajar. Believing one of his friends to have sneaked inside, he begins investigating, but he's promptly met with a menacing Michael Myers.

After a brief struggle, The Shape runs him through with his knife, pinning him to the wall. Afterward, Myers is seen admiring his handiwork, tilting his head to the side and conveying the sort of eerie inhumanity for which the character is so well known.
