Monster Story Ideas and Writing Prompts

So, you want to write a monster story? Let’s dive in for some intriguing story ideas!

Please note that the genders in these prompts and story ideas are just placeholders. It is not the intention to enforce any hurtful stereotypes or offend anyone.

Monsters in modern settings

Choose a monster and plop it into a modern setting. This allows you to incorporate the use of modern technologies and context such as cell phones, the internet, etc. to enrich your narrative. Here are some ideas:

  1. A werewolf who’s a professional tracker

    He tracks anything from missing trinkets to missing pets, and even missing people. (Originally appeared on my post Werewolf Story Ideas and Writing Prompts.)

  2. A siren who’s a bar singer

    She enchants her audience with her voice. There’s a reason that all the usual bar patrons and her coworkers know not to mess with this one, because rumor has it, she could drive anyone crazy with her voice if she wants to.

  3. A vampire who’s a doctor

    He chooses said occupation for an easy access to blood. What happens when he/she drinks blood from a patient and becomes specifically addicted to that patient’s blood? (Originally appeared on my post Vampire Romance Story Ideas and Writing Prompts.)

  4. A siren who might or might not be a serial killer

    A series of gruesome murders lead a detective to a siren, and together they form an unlikely alliance to unravel the mystery, while confronting the dark forces that seek to exploit the siren’s power.

  5. A genie who tries to collect on a century-old promise

    The genie is being re-awakened in the 20th century, and is now trying to collect on a promise. But the original promise maker has been long dead. So, the monster is coming for their nearest descendant.

  6. Dragons, whose natural habitats are gone because of deforestation

    Due to the loss of their natural homes, they decide to make city parks and zoos their new residence. (For more dragon-related story ideas, head to my post Dragon Story Ideas to Spark the Imagination.)

  7. Cerberus, the friendly dog

    He befriends a kind, blind elderly who mistakes him as a stray dog. (Originally appeared on my post Deep Dark Fantasy Story Ideas and Writing Prompts.)

  8. Hybrid monster kids trying to fit into the modern world

    They try hiding their monstrous forms with enchantments, glamours, and sometimes, cosmetics.

  9. Or write about a regular doctor whose patients include the unicorns and the centaurs

    He stumbled upon his/her specialty by accident, and now by words of mouth he has a very long writing list of various mythological and legendary creatures.

Retellings of classics

Take a classic and put your own spin into it. Here are some ideas:

  1. Odyssey by Homer

    Re-imagined as the adventure of a small child navigating the world around them. The monster Cyclop is a burly school bully, the vicious six dog head is the neighbor’s rabid dog, and the whirlpool Charybdis is the house’s vacuum cleaner. Perfect for a children’s book.

  2. Beauty and the Beast

    Told as a gender-flipped story, or mashed with another genre or setting. What if the beast is a deformed mermaid or merman? Or what if the beast has vampiric tendencies?

  3. Frankenstein by Mary Shelley

    But instead of stitching together human parts, it’s animal parts that are being stitched together, which then comes alive.

  4. Dracula by Bram Stoker

    Take a convincing historical figure and merge the figure’s personality with that of Dracula. Genghis Khan as Dracula? Or Napoleon?

  5. Minotaur

    A what-if story. What if the Minotaur of the Greek legend lives among us? Where would his mother hide him, and what would be his character’s arc?

Original monster ideas

Let your imagination loose and come up with an original narrative. To help you start, here are some ideas:

  1. The Shadow Beast

    There’s a beast who lurks in the shadows of a small town, feeding on the fears of the townsfolk.

  2. The Time Shifter

    A scientist accidentally creates a time-manipulating creature in their lab.

  3. The Dream Thief

    A malevolent entity haunts the dreams of a small town’s inhabitants, stealing fragments of their dreams and leaving them trapped in a perpetual nightmare.

  4. The Soul Collector

    In a haunted forest, the Soul Collector roams, capturing the souls of the lost and trapping them within its labyrinthine lair. A woman embarks on a dangerous quest to confront the creature and free her sister’s trapped soul.

  5. Evolution

    What if a species we’ve never considered as a threat before evolves and rises to the top of the food chain, even above humans?

    My love for kombucha (fermented tea) inspires this one. What if the organisms responsible for fermentation evolve into a whole ‘nother creature?

  6. The Waste Eater

    Scientists have successfully create a microorganism that happily devours waste. Too happily, that it grows and multiplies exponentially and threatens the lives of the humans around it.

  7. Blurred Lines

    What if for a day, the lines separating the dream world and the waking world blurs?

    All the monsters from our dream world would cross over and refuse to fade back into the dream world because their food is more abundant here in the waking world.

  8. Accidental Monster

    A toddler’s drawing of a monster comes alive. Alternatively, an art student creating a sculpture of a hypothetical creature, only for it to come alive.

  9. Monsters of Unexpected Origins

    The sun is actually a sentient being, and it’s just waken up after million years of slumber.

  10. The Molten Skin

    In an alternate world, humans molt like insect, and the discarded molten skins sometimes gain sentience and turn evil.

About Monsters

Now, let’s delve deeper into this genre.

What’s a monster, really? A monster is typically an imaginary creature in legends, fantasy, science fiction, mythology, folklore, and even religion, that is perceived as frightening, dangerous, or monstrous in appearance, behavior, or character.

The term can refer to a variety of beings, such as mythical creatures like dragons, ogres, or unicorns, or more modern representations like zombies or vampires. Monsters are often depicted as being supernaturally powerful, vicious, or malevolent, and may be used in literature, movies, or other media as symbols of fear, evil, or the unknown.

Monsters vs. demons

The difference between monsters and demons can vary depending on the context, but generally speaking:

A monster is a creature that is often depicted as being large, grotesque, and dangerous. Monsters can be fictional or legendary, and are often associated with horror or fantasy genres. While monsters can be evil and terrifying, they are not necessarily malevolent or supernatural in nature.

A demon, on the other hand, is a malevolent supernatural entity that is often associated with evil or demonic possession. In many religions and mythologies, demons are considered to be fallen angels or evil spirits, capable of possessing humans and causing harm or destruction. Demons are often depicted as having supernatural powers and abilities, and are typically associated with dark magic and the occult.

So while monsters and demons can both be scary and frightening, the key difference is that monsters are generally physical creatures, while demons are supernatural entities with malevolent intentions.

Famous stories featuring monsters

Here are some famous stories featuring monsters.

Beowulf” is an epic poem written in Old English sometime between the 8th and the early 11th century (but was not published as a book until 1815) telling the story of a hero named Beowulf who battles a monster named Grendel, as well as Grendel’s mother and a dragon.

Known as one of the earliest “modern” monster stories is Mary Shelley’s “Frankenstein” published in 1818, telling the story of a young scientist named Victor Frankenstein who creates a grotesque creature in an experiment gone wrong.

Halfway across the pond, we have “Godzilla“. This iconic movie monster first appeared in the 1954 Japanese film “Godzilla.” The character is a giant, radioactive dinosaur-like creature that wreaks havoc on cities and battles other monsters in a number of films and other media.
