# Superpower (ability)
A superpower, in the sense of an ability, is a superhuman capacity possessed by a fictional character, such as flight, invisibility, or superhuman strength, and it is the defining attribute of most superheroes and supervillains.[1](https://guides.loc.gov/science-through-pop-culture/superpowers) • [2](https://www.oxfordlearnersdictionaries.com/us/definition/english/superpower) The term belongs to popular culture rather than to science: the Library of Congress describes it as a popular culture term for any superhuman ability, found across genres and media in the fictional sphere.[1](https://guides.loc.gov/science-through-pop-culture/superpowers)
| Key fact | Detail |
|---|---|
| Definition | A special power or ability that somebody has, especially a superhero, in films and stories[2](https://www.oxfordlearnersdictionaries.com/us/definition/english/superpower) |
| Word history | Merriam-Webster dates the first known use of "superpower" to 1849, in the sense of excessive or superior power; Dictionary.com records the modern coinage as first recorded 1920–25, from super- + power[3](https://www.merriam-webster.com/dictionary/superpower) • [4](https://www.dictionary.com/browse/superpower) |
| Most common abilities | Superhuman strength, the ability to fly, and telekinesis[1](https://guides.loc.gov/science-through-pop-culture/superpowers) |
| Archetype | Superman's catalog of powers, attributed to his alien origin, Earth's lesser gravity, and the differing radiation of the Sun[5](https://sf-encyclopedia.com/entry/superpowers) |
| Boundary case | Device-assisted abilities such as Iron Man's prosthetics or Green Lantern's power ring are not readily distinguishable from superpowered beings[5](https://sf-encyclopedia.com/entry/superpowers) |
| Narrative role | Limitations and costs attached to powers create tension and require strategic decisions; Brandon Sanderson's second law argues limitations can be more interesting than powers[6](https://lore.sanjiesanworld.com/articles/power-systems-rules-costs-limits-consequences-framework/) |
## Meaning and scope
Dictionaries treat the fictional sense as a distinct meaning of the word. The Oxford Advanced Learner's Dictionary lists, alongside the geopolitical sense of a dominant nation, a second sense: "(in films and stories) a special power or ability that somebody has, especially a superhero."[2](https://www.oxfordlearnersdictionaries.com/us/definition/english/superpower) [Merriam-Webster](https://www.edgepedia.org/merriam-webster) defines it as "a power or ability (such as the ability to become invisible or to fly) of the kind possessed by superheroes: a superhuman power," and derives the adjective *superpowered* from it.[3](https://www.merriam-webster.com/dictionary/superpower) Dictionary.com's Random House-based entry defines it as a power "greater in scope or magnitude than that which is considered natural or has previously existed."[4](https://www.dictionary.com/browse/superpower)
The word's history is layered. Merriam-Webster's first known use is 1849, in the sense of excessive or superior power, decades before the comic-book meaning existed.[3](https://www.merriam-webster.com/dictionary/superpower) [Dictionary.com](https://www.edgepedia.org/dictionary-com) dates the modern compound to 1920–25.[4](https://www.dictionary.com/browse/superpower) The fictional sense became established with the superhero genre itself.
## Typical powers
The abilities most often labeled superpowers include superhuman strength, flight, and telekinesis.[1](https://guides.loc.gov/science-through-pop-culture/superpowers) The Science Fiction Encyclopedia's thematic entry catalogs the range further: the ESP and psi powers (Spider-Man's "spider sense," Daredevil's "radar sense"), invisibility, shapeshifting, transmutation of elements, elasticity, force fields, and weather control, "and so on almost without end."[5](https://sf-encyclopedia.com/entry/superpowers)
**Superman as template.** Superman, described by the [Encyclopedia](https://www.edgepedia.org/encyclopedia) as a major twentieth-century archetype, carries a large assortment of powers supposedly resulting from his alien origin, the lesser gravity of Earth compared to his homeworld Krypton, and the differing radiation of the Sun: vast strength, incredible speed, unaided flight, near-total invulnerability, X-ray vision, and heat rays from his eyes. His corresponding weaknesses are kryptonite radiation and, in comics crossovers, magic. Many later heroes possess some subset of this set; super-strength in particular is common, appearing in the Hulk, the Thing of the [Fantastic Four](https://www.edgepedia.org/fantastic-four), and Mr. Incredible.[5](https://sf-encyclopedia.com/entry/superpowers)
## Powers, devices, and the blurred boundary
A significant fraction of the superhero fraternity lacks outright superpowers and instead excels in martial arts and exotic gadgetry, like Batman, the [Blue Beetle](https://www.edgepedia.org/blue-beetle), and the Nite Owls of *Watchmen*. The dividing line between device-assisted ability and superpower is regularly blurred by far-fetched technology: the cyborg enhancements of [The Bionic Woman](https://www.edgepedia.org/the-bionic-woman) (1976–1978) and [The Six Million Dollar Man](https://www.edgepedia.org/the-six-million-dollar-man) (1973–1978), Iron Man's prosthetics, the Atom's shrinking clothing, and Green Lantern's power ring are all examples of device/user combinations not readily distinguishable from superpowered beings.[5](https://sf-encyclopedia.com/entry/superpowers) Roger Zelazny's *Lord of Light* (1967) explores this synergy directly, with "gods" who deploy both psi powers and gadgetry designed to amplify their talents.[5](https://sf-encyclopedia.com/entry/superpowers)
## History of the concept
Heroes with superhuman powers appear in mythologies throughout the world, and Jess Nevins, an independent scholar of popular fiction, traces the costumed-avenger tradition in *The Evolution of the Costumed Avenger: The 4,000-Year History of the Superhero* (Praeger, 2017) from the [Epic of Gilgamesh](https://www.edgepedia.org/epic-of-gilgamesh), dated in that account to 2100 B.C.E., through to modern comics and graphic novels.[7](https://www.bloomsbury.com/us/evolution-of-the-costumed-avenger-9781440854835/) The Science Fiction Encyclopedia notes that stories of figures with super or extraordinary powers whose actions keep the world safe almost certainly existed in some form before [Alexandre Dumas](https://www.edgepedia.org/alexandre-dumas) created the Count of Monte Cristo in 1844, and that science fiction stories of supermen go back to the beginning of the twentieth century.[8](https://sf-encyclopedia.com/entry/superheroes)
The modern superhero, and with it the standard superpower narrative, dates to 1938, when Superman debuted in *Action Comics* issue 1, created by [Jerry Siegel](https://www.edgepedia.org/jerry-siegel) and [Joe Shuster](https://www.edgepedia.org/joe-shuster), who drew on the pulp heroes [Doc Savage](https://www.edgepedia.org/doc-savage) and Gladiator.[9](https://ir.canterbury.ac.nz/server/api/core/bitstreams/5426a643-1675-493d-907d-834ddcb6fd11/content) The genre's fortunes have shifted since: after circulations soared on patriotic 1940s stories, costumed heroes had all but vanished from newsstands by the mid-1950s, a decline tied to changing tastes and to the campaign following psychiatrist Fredric Wertham's 1954 book *Seduction of the Innocent*, which led to a Congressional inquiry and to the industry's self-regulating Comics Code Authority.[10](https://time.com/7304326/fantastic-four-superhero-influence/)
## Narrative function of limits
In storytelling practice, a power is only half of the design. Writers and game designers treat limitations, costs, and consequences as the structure that makes an ability narratively usable: limitations channel creative power rather than merely restricting it, and powers that lack them tend to flatten tension.[6](https://lore.sanjiesanworld.com/articles/power-systems-rules-costs-limits-consequences-framework/) The framework's summary of [Brandon Sanderson](https://www.edgepedia.org/brandon-sanderson)'s second law holds that limitations can be more interesting than the powers themselves.[6](https://lore.sanjiesanworld.com/articles/power-systems-rules-costs-limits-consequences-framework/) Familiar examples include vampire abilities that work only at night, and progression systems in which rapid advancement without struggle diminishes narrative satisfaction.[11](https://www.kaunia.com/index.php?pageid=1189&siteid=746&todo=blog_showitem)
## Science and superpowers
Although superhero stories are fictional, many are built on scientific principles, and a substantial popular-science literature examines them. James Kakalios, a physicist at the [University of Minnesota](https://www.edgepedia.org/university-of-minnesota), uses comic-book scenarios to teach physics in *The Physics of Superheroes* (2009), covering topics from the probable cause of Krypton's explosion to the Newtonian mechanics of [Gotham City](https://www.edgepedia.org/gotham-city).[1](https://guides.loc.gov/science-through-pop-culture/superpowers) E. Paul Zehr, a neuroscientist, examines in *Inventing Iron Man* (2011) how modern technology might approximate Stark's armor.[1](https://guides.loc.gov/science-through-pop-culture/superpowers) Other titles in the Library of Congress's research guide apply protein chemistry, particle physics, robotics, and genetics to super strength, invisibility, and X-ray vision, noting that researchers have recreated some animal abilities for human use.[1](https://guides.loc.gov/science-through-pop-culture/superpowers)
