When we picture children we usually imagine giggles, playgrounds, and the first day of school—not blood‑soaked murder scenes. Yet fiction loves to twist that innocence, gifting us youngsters who wield either heroic or villainous powers. In this roundup of the 10 best worst killer kids from TV and film, we’ll see why age is no barrier to a trail of carnage.
Why These 10 Best Worst Kids Stand Out
Each of these juvenile terrors brings a unique blend of supernatural abilities, twisted psychology, or sheer brutality that makes them unforgettable. From alien‑born super‑villains to demonic possessions, they prove that darkness can bloom at any age. Buckle up, because the list is as shocking as it is entertaining.
10 Brandon Breyer (Brightburn)
Brightburn (2019) flips the classic Superman origin on its head, following the seemingly ordinary pre‑teen Brandon Breyer whose parents rescued him from a crashed alien craft. At first, Brandon appears just like any other kid, but puberty awakens a terrifying set of extraterrestrial powers—flight, super‑strength, laser vision, and a penchant for cruelty.
As his birthday draws near, the newfound abilities come with a dark attitude shift and a morbid fascination with gore. Whispering, demonic voices haunt his dreams, pushing him toward violence. The once‑well‑adjusted youngster spirals into a malevolent force, wreaking havoc on his hometown.
His reign of terror culminates in a series of gruesome murders, including a chilling scene where he stalks and brutally slays his own uncle. Brandon’s descent is a stark departure from traditional superhero fare, delivering a fresh, horrifying take on power gone awry.
9 Charlotte (The 100)
Charlotte makes a brief but memorable appearance early in the first season of The 100 (2014‑2020). Among the hundred juveniles sent to Earth from the orbital Ark, she arrives scarred by nightmares of her parents’ execution at the hands of the Ark’s Chancellor.
Initially portrayed as a timid, fragile girl, Charlotte’s story takes a dark turn when she misinterprets advice from Bellamy, who tells her to “slay [her] demons” while she’s awake. Taking his words literally, she resorts to a fatal act, stabbing the Chancellor’s delinquent son in the throat in a desperate bid to end her haunting dreams.
This shocking misinterpretation showcases how even the youngest can become instruments of lethal violence when pushed to the edge, cementing Charlotte’s place among the series’ most unsettling characters.
8 Hit‑Girl (Kick‑Ass)
Mindy McCready, better known as Hit‑Girl, stars as the fierce secondary lead in the irreverent superhero comedy Kick‑Ass (2010). After her father serves time for a crime he didn’t commit and her mother later takes her own life, Mindy’s upbringing is anything but ordinary.
Her father, newly released, rigorously trains her from a young age in martial arts, weapons handling, and tactical combat. Together they become the crime‑fighting duo Big‑Daddy and Hit‑Girl, striking fear into the hearts of criminals.
Hit‑Girl’s lethal efficiency shines in a visceral, partially first‑person sequence where she single‑handedly decimates an entire room of armed men attempting to set her father ablaze. Her blend of youthful innocence and brutal skill makes her a standout on this murderous roster.
7 Ashley Oswalt (Sinister)
The 2012 horror film Sinister follows true‑crime writer Ellison Oswalt as he moves his family into a house plagued by a series of gruesome murders. His daughter Ashley initially appears as a sweet, creative child, terrified by the ghostly children that begin to manifest after Ellipsis discovers eerie reels of home videos in the attic.
The reels document the brutal killings of the previous occupants, each accompanied by Ashley’s crayon drawings that eerily reenact the murders with a shadowy figure named Mr. Boogie lurking nearby. As Ellison delves deeper, he uncovers a chilling pattern: each family is slain by one of their own children under the influence of an ancient pagan deity, Baguul, who feeds on souls.
In a harrowing climax, Ashley, drugged and under the deity’s sway, records herself ax‑murdering her entire family and painting the walls with their blood, cementing her status as one of the most disturbingly murderous children in modern horror.
6 Number Five Hargreeves (The Umbrella Academy)
Number Five, a central figure in Netflix’s comic‑book‑inspired series The Umbrella Academy, masquerades as a 13‑year‑old while internally housing the mind of a seasoned 58‑year‑old assassin. A botched time‑travel experiment strands him for decades in a post‑apocalyptic future, where he’s recruited by a shadowy organization that governs temporal flow.
Trained into a cold‑blooded killer, Five quickly rises through the ranks, mastering the art of lethal precision. Disillusioned, he defects and attempts another time‑jump to prevent an impending apocalypse, only to miscalculate and return to his teenage body.
Despite his youthful exterior, Five remains a ruthless combatant, dispatching foes with bare hands—gouging eyes, snapping necks, and even slashing a room of time‑traveling executives with an axe in season two. His brutal efficiency makes him one of the most terrifying child assassins on screen.
5 Lilith (Supernatural)
During the third season of the CW drama Supernatural, the demon Lilith briefly possesses a young girl, imprisoning the child’s entire family under her control. While in this vessel, the girl forces her parents and grandfather to celebrate her birthday daily and mandates cake for dinner each night.
Her reign of terror escalates as she kills the family pet, murders a babysitter, and ultimately snaps her grandfather’s neck, showcasing a chilling blend of innocence and cruelty. The demonic presence eventually abandons this vessel for another, but Lilith’s legacy lingers.
Later, the demon reappears as a hallucination, tormenting one of the main protagonists during a paranormal‑induced heart attack, reinforcing her status as a youthful harbinger of horror.
4 Eleven (Stranger Things)
Eleven, affectionately known as El, is a central character in Netflix’s hit series Stranger Things (2016‑present). Locked away by a mysterious figure dubbed “Papa” and subjected to relentless experiments, she develops potent telekinetic and telepathic abilities that often cause her nose and ears to bleed.
Despite her generally kind demeanor and love for waffles, Eleven’s powers have a deadly side. She has eliminated guards attempting to imprison her, destroyed the Demogorgon—the series’ titular monster—in the first season, and caused an entire room of government agents to hemorrhage to death using only her mind.
Her telekinetic might even flings a moving van into the air, aiding her friends’ escape. Eleven’s blend of vulnerability and lethal power earns her a spot among the most formidable child killers on television.
3 Janice (Annabelle: Creation)
Janice appears in the second installment of the Annabelle saga (2017). After a bout of polio leaves her wheelchair‑bound, she begins as a compassionate girl deeply attached to her best friend, Linda, within an orphanage overseen by Sister Charlotte.
The group is later taken in by doll‑maker Mr. Mullins, whose home harbors dark secrets. Janice becomes the target of a demonic entity attached to the possessed doll Annabelle. Under the demon’s influence, she regains the ability to walk, murders Mr. Mullins, and brutally crucifies and mutilates his bedridden wife.
As the story unfolds, teenage Janice (now known as Annabelle Higgins) joins a satanic cult and later returns home to slaughter the parents who had adopted her, revealing a lifelong trajectory of murderous deeds.
2 Village of the Damned (1960)
The 1960 black‑and‑white classic Village of the Damned introduces a brood of eerie alien children, born under mysterious circumstances and linked telepathically. Adapted from The Midwich Cuckoos, these platinum‑blonde youngsters mature rapidly, appearing as nine‑ or ten‑year‑olds by age three.
Highly intelligent yet cold‑hearted, the children possess unsettling powers and a disdainful attitude toward the townsfolk. Their cruelty manifests in acts such as forcing a mother to dip her hand into boiling water as punishment and orchestrating fatal accidents.
Among their most chilling deeds, they cause a man to crash his car and compel his brother to shoot himself in the head, cementing their reputation as a collective of prepubescent predators.
1 Lizzie Samuels (The Walking Dead)
Lizzie Samuels makes a disturbing appearance in the fourth season of AMC’s The Walking Dead (2010‑2022). Struggling to comprehend the threat posed by the undead, she refers to walkers as “friends,” even attempting to play games with them.
Her warped perception reaches a horrifying climax when she tries to prove walkers aren’t dangerous by stabbing her younger sister Mika to death, then waiting for her to reanimate, insisting she would cause no harm. She nearly repeats this act with infant Judith, were it not for the intervention of two adults.
Lizzie’s chilling actions underscore the terrifying potential for innocence to mask murderous intent, securing her place at the top of this unsettling list.
