There was a time when the scariest thing in your bedroom wasn’t under the bed. It was standing on the dresser.
Long before action figures became highly detailed collector’s pieces, the toy aisles of the 1980s were home to an incredible parade of skeletons, mutants, vampires, winged monsters and creatures that looked suspiciously like they had escaped from late-night horror movies.
Some glowed in the dark. Some had faces that transformed. And at least one seemed disturbingly interested in what was happening inside its own rib cage.
We carried these things home in shopping bags from Toys “R” Us, Kay-Bee and Kmart, then placed them alongside our G.I. Joe soldiers and heroic warriors as though nothing unusual had happened.
Looking back, it’s astonishing what toy companies were willing to put on a children’s wish list—and thank goodness they did.
With Halloween almost here, we’re opening the toy chest and counting down 10 of the scariest original action figures of the 1980s.
These are the genuine vintage toys, not modern redesigns, reproductions or AI-generated recreations.
Our rankings celebrate unsettling designs, unforgettable gimmicks and pure childhood nightmare fuel. You might disagree with the order. In fact, we’re counting on it.
THE RULES OF THE COUNTDOWN
Original 1980s action figures only. Rankings are subjective, and the photographs show authentic vintage figures, generally photographed by modern collectors, retailers and auction houses.
NUMBER 10 | MASTERS OF THE UNIVERSE
MANTENNA
When your eyeballs became a weapon
MATTEL | 1985

Not every childhood nightmare required fangs or a skull. Sometimes all it took was an insect-like creature whose enormous red eyes suddenly sprang outward from its head.
Mantenna belonged to Hordak’s Evil Horde, and while he wasn’t necessarily the most powerful villain in the Masters of the Universe universe, he might have been among the strangest.
The original Mattel figure featured a remarkable gimmick. Move the lever on his back, and those enormous eyes popped out on stalks.
It was both hilarious and unnerving.
Everything about the figure looked slightly wrong in the best possible way. His red head, angular ears, dark blue limbs and oversized stare gave him the appearance of a creature that belonged in a science-fiction horror film.
Put him next to He-Man and Skeletor, and the toy shelf suddenly felt like a very different place.
CREEPIEST DETAIL: Those spring-loaded, pop-out eyes.
NUMBER 9 | MASTERS OF THE UNIVERSE
HORDAK
Eternia’s skeletal warlord
MATTEL | 1985

Skeletor may have been the villain every kid knew, but Hordak looked like a villain who had already won.
With his bone-white face, dark eyes, blood-red bat emblem and intimidating armor, Hordak seemed less like an ordinary action-figure villain and more like a medieval executioner crossed with a science-fiction vampire.
Even his expression was unsettling.
Where Skeletor seemed to be constantly shouting threats from across Castle Grayskull, Hordak looked like the kind of villain who didn’t need to raise his voice at all.
His original action figure possessed a wonderfully sinister simplicity. There were no complicated electronics or extraordinary transformations required. The sculpt did most of the work.
The Evil Horde’s leader was frightening because of how little emotion his face conveyed.
His pale, skull-like appearance and severe armor made him stand apart from the brighter heroes and villains of Eternia.
CREEPIEST DETAIL: The cold, expressionless skull-like face.
NUMBER 8 | SILVERHAWKS
MON*STAR
A monster hiding inside a criminal mastermind
KENNER | 1987

The heroes of SilverHawks were sleek, shiny metallic adventurers. Their greatest enemy looked like someone had crossed a space pirate with a creature from the darkest corner of a horror comic.
Mon*Star was a terrifying explosion of angry red armor, spikes and monstrous features.
Kenner translated the character’s sinister transformation into one of the more unusual action features of the decade.
Squeeze the figure’s knees, open the chest mechanism and rotate the hidden head to change his appearance.
It was a remarkably inventive trick for a children’s toy.
But even without the transformation, Mon*Star was intimidating. His spiked red appearance made him look downright demonic beside the streamlined SilverHawks figures.
There was something wonderfully outrageous about a toy that combined the appeal of futuristic action heroes with a villain who wouldn’t look out of place in a monster movie.
CREEPIEST DETAIL: The hidden rotating head inside his chest.
NUMBER 7 | MASTERS OF THE UNIVERSE
MOSQUITOR
The Evil Horde’s very own bloodsucker
MATTEL | LATE 1986 / 1987 WAVE

Photo: Vaults of Grayskull.
Of all the horrifying ideas toy companies developed during the 1980s, Mosquitor’s concept might have been one of the most outrageous.
Imagine sitting in a Mattel design meeting and suggesting a warrior with the head of a giant mosquito who could appear to pump blood through his chest.
Someone not only approved that idea—they actually manufactured it.
Mosquitor was a member of the Evil Horde whose frightening insect-like appearance would have been enough to earn him a place on this list.
But Mattel went much further.
Inside his transparent chest was red fluid that moved when the figure’s action feature was activated, simulating the pumping of blood.
For children already familiar with vampires and creepy-crawly monsters, there was only one possible interpretation: this thing was feeding on its victims.
The genius of Mosquitor is that he was simultaneously colorful, imaginative, grotesque and unmistakably a toy made for children.
Few action figures better represent the fearless creativity that defined the decade.
CREEPIEST DETAIL: The moving red fluid visible through his chest.
NUMBER 6 | THUNDERCATS
MUMMY MUMM-RA
The ancient evil underneath the bandages
LJN | 1986 MAIL-AWAY OFFER
Photo: Vintage collector listing.
For many ThunderCats fans, the truly frightening version of Mumm-Ra wasn’t his enormous, muscular transformed appearance.
It was the ancient, shriveled mummy who inhabited the Black Pyramid.
This version looked less like a conventional cartoon villain and more like a walking corpse that had escaped from a forgotten tomb.
LJN brought that unsettling incarnation to life as a special mail-away action figure during the original ThunderCats toy line.
With his greenish face, bandaged body, red hood and eerie staff, Mummy Mumm-Ra possessed an atmosphere entirely different from most children’s action figures.
There were no elaborate transformation features or electronic gimmicks to distract from the design.
He simply stood there looking like an ancient curse.
Sometimes the scariest monsters are the ones that don’t move very much.
CREEPIEST DETAIL: The decaying face peering out from beneath the red hood.
NUMBER 5 | G.I. JOE: A REAL AMERICAN HERO
NEMESIS ENFORCER
Cobra-La’s silent, winged nightmare
HASBRO | 1987

Photo: Vintage collector photograph.
For a franchise built around military commandos, tanks, helicopters and high-tech weaponry, Cobra-La represented one of the strangest creative turns imaginable.
And then came Nemesis Enforcer.
Introduced in the 1987 Cobra-La three-pack, this hulking, winged guardian looked like something that belonged in a horror fantasy rather than a military adventure.
His pale skin, purple armor, enormous wings and strange green tendril accessory gave him the appearance of an ancient creature that should never have escaped its underground kingdom.
Even his filecard leaned into the imagery of legendary monsters and creatures of the night.
For longtime G.I. Joe fans, Cobra-La remains a divisive subject. Some collectors love the wild science-fiction direction, while others prefer the realistic military roots of the line.
But regardless of which side of that debate you occupy, Nemesis Enforcer remains one of the most visually unforgettable figures of the original Real American Hero era.
He looked like a horror movie had suddenly invaded the G.I. Joe aisle.
CREEPIEST DETAIL: The batlike wings and strange biological tendrils.
NUMBER 4 | INHUMANOIDS
TENDRIL
The swamp creature that could reach across your bedroom
HASBRO | 1986

Hasbro’s Inhumanoids gave us monsters large enough to dominate almost any childhood toy collection, and Tendril might have possessed the most frightening silhouette of them all.
His enormous arms stretched outward into oversized claws. His face looked as though a swamp had somehow grown teeth. His body resembled something that had crawled from the depths of the earth after centuries of decay.
Compared with the comparatively small G.I. Joe figures, Tendril looked enormous.
And that was the point.
Inhumanoids monsters were designed to tower over the heroes, and Tendril was particularly effective at making a bedroom battlefield feel terribly unsafe.
He wasn’t just another villain on the shelf. He was the thing that stood behind the villains, reaching over them.

Even the original packaging added to the horror. The purple, jagged-rock design surrounding the massive figure made the box resemble the entrance to some underground world of monsters.
It was difficult to believe such a grotesque creation could be found in an ordinary toy store.
CREEPIEST DETAIL: The impossibly long arms, oversized claws and fleshy mouth.
NUMBER 3 | MASTERS OF THE UNIVERSE
SCARE GLOW
The ghost that refused to stay in the dark
MATTEL | LATE 1986 / 1987 WAVE

Photo: Collector Archive.
Of course Scare Glow makes this list.
With his skeletal body, spectral purple cape and eerie green weapon, he looked like Halloween made plastic.
But Mattel made the design even more spectacular by casting the body in glow-in-the-dark material.
Charge the figure beneath a lamp, turn off the bedroom lights, and suddenly your toy shelf contained an actual apparition.
For a child in the 1980s, it was pure magic.
Scare Glow arrived near the end of the original Masters of the Universe era. Although collectors generally associate him with the 1987 assortment, period advertisements show that the figure was already appearing in late 1986.
His arrival felt almost too good to be true: a luminous skeleton wandering among Eternia’s colorful warriors and villains.
He was the perfect combination of spooky design, imaginative play value and unforgettable presentation.
Decades later, the original figure remains one of the most recognizable ghostly creations of the entire toy decade.
CREEPIEST DETAIL: The glowing skeleton that remained visible long after lights-out.
NUMBER 2 | INHUMANOIDS
METLAR
The monster at the center of the earth
HASBRO | 1986

Photo: Vintage collector listing via eBay.
Metlar was what happened when a toy company decided its villain should resemble a living volcanic catastrophe.
His gigantic horned head, exaggerated jaw, prominent teeth and enormous body made him look like something that had escaped from a subterranean horror epic.
Everything about the original 1986 figure suggested overwhelming power.
Where most action figures stood only a few inches tall, Metlar occupied a startling amount of shelf space.
He was the monster who could tower over an entire battlefield of ordinary figures, staring straight ahead with the confidence of something capable of crushing every hero in sight.
There was a remarkable sense of menace in his design.
Even his original retail packaging looked like a poster for a forgotten monster movie.

The monstrous sculpt, gigantic size and menacing facial expression made Metlar one of the most intimidating children’s toys of the decade.
Had another company attempted to sell this exact design as an adult horror collectible, nobody would have questioned it.
Instead, Hasbro put him in the children’s toy aisle.
And we loved him for it.
CREEPIEST DETAIL: The gaping mouth filled with enormous teeth.
NUMBER 1 | INHUMANOIDS
D’COMPOSE
The most terrifying toy of the decade
HASBRO | 1986

Photo: Vintage collector imagery via eBay.
And here we are. Number one.
The action figure that perhaps best represents the moment when childhood science fiction crossed completely into nightmare territory.
D’Compose.
Of all the extraordinary monsters introduced during the 1980s, few were as visually disturbing as this gigantic skeletal creature from Hasbro’s Inhumanoids.
He possessed enormous clawed limbs, a skull-like head, exposed-looking innards and a massive rib cage that could open to imprison other action figures.
Think about that for a moment.
This was a children’s toy whose signature feature involved trapping its victims inside its own chest.
And somehow that was only part of what made him frightening.
The original Hasbro Toy Fair catalog described a towering 14-inch monster with glowing fangs and an enormous rib cage designed to capture unfortunate victims.
In the animated series, D’Compose possessed the horrifying ability to transform living creatures into monstrous, decaying servants.
The concept was frightening enough on television. Holding the enormous figure in your hands somehow made it even stranger.
His hollow-looking red eyes, bleached skeletal frame and oversized orange claws gave him an appearance unlike anything else in the ordinary action-figure aisle.
He wasn’t a villain who happened to wear a skeleton costume.
He was the nightmare itself.
ORIGINAL 1986 PACKAGING

Imagine being eight years old and finding this towering skeletal creature standing at the foot of your bed in the middle of the night.
No batteries required. No complicated action feature necessary.
D’Compose was terrifying simply by standing there.
And that makes him our choice for the scariest action figure of the entire decade.
CREEPIEST DETAIL: The enormous opening rib cage that could imprison other action figures.
THE TOY AISLE WAS OUR FIRST HORROR THEATER
The magic of these figures wasn’t that they were realistic.
They weren’t.
The magic was that their creators understood how to make a single unforgettable feature capture the imagination of a child.
A pair of eyes that suddenly sprang outward. A chest filled with moving red fluid. Enormous wings attached to a mysterious biological warrior. A skeleton that continued glowing long after the bedroom lights had been switched off.
These weren’t merely toys.
They were gateways into worlds of horror, fantasy and imagination.
And for children who grew up during the 1980s, they were also a reminder that the most memorable adventures often began on the bedroom floor.
We didn’t need screens, apps or elaborate digital effects to invent our stories.
All we needed was an action figure, a little imagination and the courage to reach into the toy chest after the lights went out.
Forty years later, many of those once-frightening plastic monsters occupy places of honor in our adult collections.
We carefully restore them, display them, photograph them and remember the excitement of discovering them for the very first time.
And occasionally, when the room is quiet and the lights are low, we might even remember how frightening they once seemed.
That was the magic of being a kid in the 1980s.
NOW IT’S YOUR TURN!
