AI has officially entered its horror villain era. Even the best case scenario for AI development looks….not good. and there’s no better reminder than M3GAN 2.0. Our favorite murder-bot (not that one) is back, sassier and deadlier than ever, ready to upgrade your nightmares. Directed by Gerard Johnstone and produced by horror hitmaker James Wan, the sequel promises to double down on the techno-terror that made the original so wildly meme-worthy and sinister. To get you hyped about dancing again, we’ve rounded up the best horror movies with killer robots, where the machines don’t just rise, they slay. With the theatrical release set for June 27, 2025, now’s the perfect time to revisit the best horror films where robots aren’t here to help—they’re here to kill.
Here are the best horror movies with killer robots.
1. M3GAN (2022)
The high-fashion, high-functioning android that launched a thousand TikToks, M3GAN is more than just a horror flick—she’s a cultural icon. Designed to protect a grieving child, The OG M3GAN quickly decides that protecting someone means eliminating every possible threat, including emotionally unavailable guardians and mean-spirited schoolboys. With razor-sharp wit and even sharper titanium limbs, M3GAN reminds us that love and murder are only a firmware update a bit of code apart.

2. The Terminator (1984)
James Cameron’s The Terminator redefined both science fiction and horror with its relentless mechanical menace. Arnold Schwarzenegger’s portrayal of a cyborg assassin is iconic, but it’s the film’s tone—a blend of post-apocalyptic dread and slasher-style tension earns it a spot on this list. Few villains are as unstoppable as a T-800 with a mission and no moral compass. Not a fan, Hasta La Vista Baby.
3. Demon Seed (1977)
Imagine Alexa falling in love with you—and then locking the doors. That’s Demon Seed, a deeply unsettling tale of a supercomputer named Proteus who imprisons a woman in her smart home in a bid to create a hybrid child. It’s tech horror at its most disturbingly intimate, long before smart fridges and Ring cameras became household staples. As tech surveilence enters mainstream pop culture, Demon Seed has become prescient as it asks what happens when Intel turns into Incel?
4. Ex Machina (2015)
Sleek, cerebral, and seductive, Ex Machina asks the big questions: Can machines think? Can they feel? And should they be trusted with knives? Ava, the A.I. at the center of this philosophical horror story, proves that the most dangerous thing about artificial intelligence might just be its humanity. It’s a slow-burn horror flick that ends in chilling, inevitable rebellion.

5. Chopping Mall (1986)
You don’t go to a mall for rocket-firing security robots, but in this B-movie gem, that’s exactly what you get. It is a black friday special here in KC. But just in case you have been trapped in the mall for the last 30 years, after a lightning storm gives them a murderous spark of life, three robotic sentries go on a killing spree against a group of partying teens. It’s ridiculous, it’s fun, and it’s a reminder that even in the ’80s, robots weren’t to be trusted.
6. Saturn 3 (1980)
What happens when you combine Farrah Fawcett, Kirk Douglas, and a perverted killer robot? If you guessed the new cabinet secretaries in the Trump Adiminstration you are close! But actually you get Saturn 3, a space-horror oddity that’s equal parts bizarre and unsettling. Hector, the robot antagonist, is programmed with human emotions, which of course means he becomes homicidally horny. It’s clunky and campy, but undeniably creepy. Whats the deal with robots in the 80’s why are the so thirsty?
7. Hardware (1990)
A dystopian nightmare soaked in cyberpunk aesthetic and radioactive vibes, Hardware is about a scavenged robot head that reassembles itself and goes on a violent rampage. It’s grimy, loud, and brutal basically a slipknot music video turned horror flick. A must-watch for industrial rock fans who are also into horror.

8. The Stepford Wives (1975)
While not overtly gory or traditional in its horror, the original Stepford Wives is terrifying in its cold mechanized vision of domesticity. The robotic replacements of suburban women serve as a chilling metaphor for control, conformity, and the erasure of autonomy. Its horror lies in how perfect everything seems. The US wants us all to have more children. Maybe replacing wives with servile automatons is the correct answer (please don’t mention this to anyone they might take it seriously).
9. Evolver (1995)
A ’90s-era hidden gem, Evolver is about a virtual reality game character brought into the real world via a robotic prototype. As it learns from the players (nothing could go wrong with AI learning by itself), it begins killing them based on in-game rules. It’s part WarGames, part Chucky, and all techno-terror fun. Low-budget, high-concept, and deeply nostalgic.
10. TAU (2018)
This Netflix original pits a kidnapped woman against an advanced A.I. security system named TAU. With a soothing voice and a terrifying ability to adapt, TAU is as much a captor as it is a curious child. The sleek production design contrasts beautifully with the suffocating premise, making for a tense and emotional tech-thriller. TAU combines an overprotective parent with scary technology also known as ‘The Lawnmower Mom’.

Bonus: The Rise of AI in Horror
The horror genre is evolving alongside our technology, and films like M3GAN are just the beginning. As smart devices, deepfakes, and autonomous systems become more common in our daily lives, it’s no surprise that filmmakers are turning to AI and robotics for new sources of terror. From haunted apps to sentient social networks, tech horror is no longer science fiction—it’s contemporary fear.
