Fantasy and science fiction are distinct genres, though they sometimes overlap

Fantasy is a genre that relies on the supernatural

Fantasy is a literary genre that embraces supernatural and magical elements. While the stories often follow common narrative archetypes, like a quest, they frequently take place in elaborately constructed worlds, which sometimes have their own complex physics, lifeforms, and societies.

Fantasy has dozens of subgenres

“Fantasy” itself is a rather broad way of characterizing fiction. The genre encompasses many subgenres, including epic (like JRR Tolkein’s “Lord of the Rings”), dark (like Neil Gaiman’s “Coraline”), or even superhero (like your favorite Marvel or DC comics).

Fantasy is heavily influenced by myths, legends, and folk tales

In fantasy, anything is possible, mirroring the supernatural worlds of history’s earliest stories. The narrative voice of fantasy is often similar to early tales, too, with an affinity for the magisterial rather than the contemporary.

JRR Tolkien believed fantasy literature was an entirely different world

Tolkien effectively invented modern fantasy, which often relies on an intricate universe, complete with its own languages, cultures, lifeforms, physics, and systems. When an author did this effectively, he called it “Faërie”—a sort of enchantment that transports the reader into the fictional world.

One writer believes fantasy is a form of realism

The literary genre has become massively popular in the 2020s, turning a previously marginal form into a mainstream concern. Spufford, a literary novelist who grew up loving books that explored fantastic worlds, argues that fantasy is so popular because it so accurately reflects the real world.

The word ‘fantasy’ wasn't used to describe the genre until the 20th century

The word—at least as a word used to describe fiction—didn’t appear in the Oxford English Dictionary until 1949. Scholars believe that’s due to the arrival of the Magazine of Fantasy and Science Fiction, an influential publication, and the rise in fantasy’s popularity following World War II.

Fan fiction relies on tropes and subgenres

Fan fiction sites often appear to be littered with inscrutable codewords, with stories labeled as "AU," "drabble," or "PWP." These alert readers to elements of a fan fiction: "AU" is an alternative universe narrative; "drabble" is a very short story; "PWP" stands for "plot? What plot?"

Dystopian literature is a form of speculative fiction

The classification includes any fiction that "speculates" about how society might operate in the future or in contexts different from the present reality. The genre is an umbrella term for science fiction, fantasy, alternative historical fiction, dystopian and utopian fiction, and apocalyptic and post-apocalyptic fiction.

Science fiction or new technology?

Dystopian literature is no longer relegated to the page, with innovations like the Tesla Cybertruck and Meta virtual reality headsets mirroring the aesthetics of texts like "The Running Man" and "Neuromancer." In this essay, Casey Michael Henry argues that the images from these works remain while their messages have faded.

A lot of high fantasy relies on constructed languages

In "Lord of the Rings," there's Elvish. In "Avatar," it's Na'vi. In "Game of Thrones," it's Dothraki. The languages draw readers into these fictional stories, imbuing the worlds with a sense of realism. Linguist John McWhorter argues these are real languages because they have grammatical rules and evolve over time.

Early English fantasy writers built on horror and Gothic texts

After the success of 19th-century books like Mary Shelley’s “Frankenstein” and Robert Louis Stevenson’s “The Strange Case of Dr. Jekyll and Mr. Hyde,” readers were eager for more stories that deviated from realism. Early 20th-century texts like George MacDonald’s “Phantastes” and Lord Dunsany’s “The King of Elfland’s Daughter” met the moment, laying the groundwork for the fantasy genre.

Some fan fiction allows readers to place themselves in their favorite stories

One subgenre of fan fiction is called "self-insert." It's exactly as it sounds: The form takes a preexisting story and inserts a reader proxy into the world of the story, acting as a form of wish-fulfillment.

Ursula K. Le Guin worked to dismantle fantasy's clichés

The author is one of the genre’s most legendary names, constructing high fantasies like “The Earthsea Cycle” that detail intricate new worlds. In 2004, she delivered a lecture criticizing books and movies that rely on a simple formula: white characters, Medieval settings, and a battle between good and evil. “Whenever I find a fantasy that is set in a genuinely imagined society and culture instead of this lazy-minded, recycled hokum,” she said, “I feel like setting off fireworks.”

A comparative analysis of the romance and horror genres' overlap

Both genres aim to make their readers' hearts pound, albeit in different ways. Romance novelist Trilina Pucci argues that the gap between the two aims is much slimmer than it may seem, with some horror tropes (like a man enraged by the abuse of his wife) and romance tropes (like the subgenre of dark romance) blurring the line.

Horror stories often rely on tropes

All literary genres use tropes, a word used to describe established plot devices, character types, and themes. Horror has many of them, like the "Creepy Child" and the "Evil Mask." Some are based on folklore, like the "Deal with the Devil."

Fan fiction implies art is an ongoing, communal practice

Although some serious literary types disregard fan fiction, other academics consider it a fascinating development in art and communication, one that allows everyday people to participate in worldbuilding and storytelling.

How 'Star Wars' changed science fiction

The popularity of "Star Wars" shifted the market away from the more literary, and sometimes cynical, science fiction of the 1960s and '70s. In the wake of George Lucas' space opera, publishers and studios wanted similarly optimistic adventure stories. In time, though, writers like William Gibson would react against that and, in turn, create the "cyber punk" subgenre.

Fan fiction is now studied at universities, including Princeton and Harvard

Some professors approach the genre as a unique form of literature that expands the boundaries of art. Comparative literature courses read the source material as well as its fan fiction byproducts, asking students to analyze the conditions that might've produced such dramatic reinterpretations.

How facts, hypotheses, theories, and laws in science differ from everyday language

Facts are observations of the world, and they can be pooled together for a given phenomenon to develop a hypothesis—a proposed explanation consistent with observations that requires further investigation. Experiments and additional data can rule out many hypotheses or graduate a proposed explanation into a widely accepted and validated theory.

Distinguishing between scientific theories and laws, and why both are on equal footing

Scientific laws describe outcomes of specific conditions, and scientific theories explain why those outcomes occur. Both are supported by observational and experimental data and can each inform one another, but neither can become the other. Instead, additional data can improve each towards more accurate descriptions and explanations of reality.

Fan fiction has slowly become a part of mainstream publishing

In 2025, the SenLinYu fantasy novel "Alchemised," which began as "Harry Potter" fan fiction, became a bestseller after being traditionally published; its movie rights were sold for over $3M. The mainstreaming of the genre is due to a combination of factors, including publishing's interest in the hard metrics that fan fiction websites provide.

A scientific analysis of famous time travel stories

This 8-minute video explores how time travel influences the narrative arc of several movies, books and video games, from Harry Potter to A Christmas Carol. (Warning: it contains spoilers!) J.K. Rowling and Charles Dickens set myriad parameters as they’re worldbuilding to avoid paradoxes and create quasi-logical timelines. By drawing diagrams as he’s speaking, the video breaks down how time works in some of popular culture’s most beloved fictional universes.

JRR Tolkien redefined fantasy for a new generation

Tolkien's debut novel, 1937's "The Hobbit," was aimed at young adults, yet it felt far more serious than the whimsical tales of Lewis Carroll or L. Frank Baum. "What Tolkien does is take the 'otherworld' fantasy developed in the 19th century and makes it child-sized, melding it with folklore and Norse myth," notes Farah Mendlesohn, the author of "Rhetorics of Fantasy."

Several bestsellers began as fan fiction

Ali Hazlewood's "The Love Hypothesis" began as "Star Wars" fan fiction. Cassandra Clare's "Mortal Instruments" series was about "Harry Potter" characters Draco Malfoy and Ginny Weasley. Anna Todd's "After" series was an example of "real life fiction," or fan fiction that is about real people rather than fictional ones (the books were originally based on the boy band One Direction).

Dystopian literature is focused on oppressive societies

The subgenre can come in many forms, but its shared traits are the way it reflects the anxieties and satirizes the utopian thinking of its writers’ societies. One of the earliest examples is Jonathan Swift's "Gulliver's Travels."

One 'Harry Potter' fan fiction deals with cognitive science and philosophy

Eliezer Yudkowsky's "Harry Potter and the Methods of Rationality" is not your typical fan fiction: It uses JK Rowling's fictional universe to wrestle with rationalist philosophy and the physics behind the magic taught at Hogwarts. The book went on to become popular in Silicon Valley, especially in the effective altruism movement.

Romantasy fans explain why they think the genre is so maligned

Romantasy grows more popular every year, but that doesn't mean it's taken seriously as literature. Hosts from KPBS' "The Finest" attended Comic Con 2025 to get romantasy fans' takes on the genre's unserious reputation.

Fan fiction is an unauthorized reinterpretation of a copyrighted story

Writers have always reinterpreted and retold others' stories. (John Milton, for example, used characters from the Bible in "Paradise Lost.") Fan fiction, though, refers to unauthorized, creative retellings of copyrighted stories intended for other fans.

In comic books, cosmic rays have been described as capable of accelerating evolution, granting humans superpowers, restoring health and energy, and powering advanced technology.

Understand the differences between manga and comics

Manga and comics—often conflated with one another—are two distinct art forms. Manga is predominantly black-and-white, with long and continuous story arcs by a consistent creator. Western comics, meanwhile, are done in full color, released as individual issues, often feature multiple creative teams, and encourage shorter and self-contained narratives.

Modern fan fiction exists in a legal gray area

Modern copyright law prohibits using someone's intellectual property (like a character) without their permission. By and large, fan fiction is tacitly condoned by copyright holders because it's commonly distributed for free. If anything, the copyright holders often benefit by allowing passionate fan communities to flourish.

One data scientist argued that fan fiction improved writing

In an academic study, University of Washington professor Cecilia Aragon found that fan fiction often teaches young writers how to craft stronger sentences and convey complex ideas effectively. Much of that comes from the larger fan fiction community, which regularly comments on others' stories, offering kind-hearted constructive criticism in what she calls "distributed mentoring."

Horror is an artistic genre aimed at scaring its audiences

Whether it's a movie, novel, comic book or any of the genre's other terrifying incarnations, horror's primary purpose is to scare its audiences. Throughout its history, the style has evolved and splintered, and now includes many subgenres, like the slasher flick, the found footage film, and even the horror comedy.

Fanfiction proliferated on fan-made sites in the 1990s

As the internet became more accessible in the '90s, fanfiction writers created websites dedicated to publishing stories about their favorite characters. Still, the hobby was far from mainstream. As one writer from that time said, "Going to Star Trek/comic book conventions in the '80s and '90s was something nerds did. Telling people you read or wrote fan fiction put you in the super geek category."

If a publisher wants to sell fan fiction, they encourage writers to change key details

Historically, companies that publish popular fan fiction have their authors change a few details—like character names, settings, or other details—to avoid potential copyright violations. Many believe the risk is worth the reward, though the legality remains murky. (Some users may experience a paywall.)

Literary theorists distinguish between ‘terror’ and ‘horror’

In her essay “On the Supernatural in Poetry,” gothic novelist Ann Radcliffe defined “terror” as the lurking, unseen specter in a story—something that defined gothic literature. “Horror,” on the other hand, was the explicit portrayal of it. For her, the former was artistic, while the latter was cheap.

The ‘Universal Monsters’ series solidified horror as a film genre

Before 1931, most scary movies were billed as “mystery” or “suspense” with grounded explanations for anything "supernatural." That changed with “Dracula,” which presented the character as a real vampire who drank victims' blood. Universal continued adapting similar titles, including HG Wells’ “The Invisible Man” and Edgar Allan Poe’s short stories.

Fanfic can provide fans with wish fulfillment

Rather than complaining about a writer's decisions, fan fiction is interactive, providing the fandom with the opportunity to tell the story in the way they see fit. That's especially evident in "shipping," a popular fan fiction trope that's focused on the romantic pairing of characters who are not romantically involved in the source material.

Unpacking the rapid rise of romantasy, the genre that blends fantasy and romance

The subgenre—primarily aimed at female readers and sometimes bordering on erotica—has become a sensation, due in no small part to its popularity on social media platforms like TikTok. Writers like Sarah J. Maas and Rebecca Yarros harken back to early Gothic works, which similarly sought to combine the supernatural and the erotic.
