The Marvel Universe is a fictional shared universe where the stories in most American comic book titles and other media published by Marvel Comics take place. Superhero teams such as the Avengers, the X-Men, the Fantastic Four, the Guardians of the Galaxy, and many Marvel superheroes live in this universe, including characters such as Spider-Man, Captain America, Iron Man, Thor, the Hulk, Ant-Man, the Wasp, Wolverine, Black Panther, Doctor Strange, Daredevil, and Captain Marvel, Blade, Black Widow, Hawkeye, Mister Fantastic, among numerous others. It also contains well-known supervillains such as Doctor Doom, Magneto, Ultron, Thanos, Loki, The Green Goblin, Kang the Conqueror, Red Skull, The Kingpin, Doctor Octopus, Carnage, Apocalypse, Dormammu, Mysterio, Electro, and the Vulture. It also contains antiheroes such as Venom, Namor, Deadpool, Silver Sable, Ghost Rider, The Punisher, Elektra, and Black Cat.
A fictional universe, also known as an imagined universe or a constructed universe, is the internally consistent fictional setting used in a narrative or a work of art. This concept is most commonly associated with works of fantasy and science fiction, and can be found in various forms such as novels, comics, films, television shows, video games, and other creative works.
Metropolis is a fictional city appearing in American comic books published by DC Comics, best known as the home of Superman and his closest allies and some of his foes. First appearing by name in Action Comics #16, Metropolis is depicted as a prosperous and massive city in the Northeastern United States, in close proximity to Gotham City. In recent years, it has been stated to be located in New York.
A parallel universe, also known as an alternate universe, parallel world, parallel dimension, alternate reality, or alternative dimension, is a hypothetical universe co-existing with one's own, typically distinct in some way. The sum of all potential parallel universes that constitute reality is often called the "multiverse". Another common term for a parallel universe is "another dimension", stemming from the idea that if the 4th dimension is time, the 5th dimension—a direction at a right angle to the fourth—is a direction into any of the alternate spacetime realities.
A fantasy world or fictional world is a world created for fictional media, such as literature, film or games. Typical fantasy worlds feature magical abilities. Some worlds may be a parallel world connected to Earth via magical portals or items ; an imaginary universe hidden within ours ; a fictional Earth set in the remote past or future ; an alternative version of our History ; or an entirely independent world set in another part of the universe.
The DC Universe (DCU) is the shared universe in which most stories in American comic book titles published by DC Comics take place. In context, the term "DC Universe" usually refers to the main DC continuity. It contains various superheroes such as Superman, Batman, Wonder Woman, Aquaman, and Flash; as well as teams such as the Justice League, the Suicide Squad, and the Teen Titans. It also contains well-known supervillains, including Joker, Lex Luthor, Cheetah, Reverse-Flash, and Darkseid.
Military science fiction is a subgenre of science fiction and military fiction that depicts the use of science fiction technology, including spaceships and weapons, for military purposes and usually principal characters who are members of a military organization, usually during a war; occurring sometimes in outer space or on a different planet or planets. It exists in a range of media, including literature, comics, film, television and video games.
An alternative universe is a setting for a work of fan fiction that departs from the canon of the fictional universe that the fan work is based on. For example, an AU fan fiction might imagine what would have taken place if the plot events of the source material had unfolded differently, or it might transpose the characters from the original work into a different setting to explore their lives and relationships in a different narrative context. Unlike typical fan fiction, which generally remains within the boundaries of the canon set out by the source material, alternative universe fan fiction writers explore the possibilities of pivotal changes made to characters' history, motivations, or environment, often combining material from multiple sources for inspiration. Characters' known motivations may vary considerably from their decisions in the canonical universe. The author of an alternative universe story thus can use the same characters, but send them down different paths to achieve a completely different plot.
Earth-Two is a setting for stories appearing in American comic books published by DC Comics. First appearing in The Flash #123 (1961), Earth-Two was created to explain differences between the original Golden Age and then-current Silver Age versions of characters such as the Flash, and how the current (Earth-One) versions could appear in stories alongside earlier versions of the same character concepts. Earth-Two includes DC Golden Age heroes, including the Justice Society of America, whose careers began at the dawn of World War II, concurrently with their first appearances in comics. Earth-Two, along with the four other surviving Earths of the DC Multiverse, were merged into one in the 1985 miniseries Crisis on Infinite Earths.
Earth Prime is a term sometimes used in works of speculative fiction, most notably in DC Comics, involving parallel universes or a multiverse, and refers either to the universe containing "our" Earth, or to a parallel world with a bare minimum of divergence points from Earth as we know it — often the absence or near-absence of metahumans, or with their existence confined to fictional narratives like comics. The "Earth Prime" of a given fictional setting may or may not have an intrinsic value to or vital connection to the other Earths it exists alongside.
The Negative Zone is a fictional setting, an antimatter universe appearing in American comic books published by Marvel Comics. The location is depicted in various publications from Marvel, most frequently in Fantastic Four and Captain Marvel. Created by Stan Lee and Jack Kirby, it first appeared in Fantastic Four #51.
Subterranean fiction is a subgenre of speculative fiction, science fiction, or fantasy which focuses on fictional underground settings, sometimes at the center of the Earth or otherwise deep below the surface. The genre is based on, and has in turn influenced, the Hollow Earth theory. The earliest works in the genre were Enlightenment-era philosophical or allegorical works, in which the underground setting was often largely incidental. In the late 19th century, however, more pseudoscientific or proto-science-fictional motifs gained prevalence. Common themes have included a depiction of the underground world as more primitive than the surface, either culturally, technologically or biologically, or in some combination thereof. The former cases usually see the setting used as a venue for sword-and-sorcery fiction, while the latter often features cryptids or creatures extinct on the surface, such as dinosaurs or archaic humans. A less frequent theme has the underground world much more technologically advanced than the surface one, typically either as the refugium of a lost civilization, or as a secret base for space aliens.
In science fiction and fantasy, floating cities and islands are a common trope, ranging from cities and islands that float on water to ones that float in the atmosphere of a planet by purported scientific technologies or by magical means. While very large floating structures have been constructed or proposed in real life, aerial cities and islands remain in the realm of fiction.
Within Marvel Comics, most stories take place within the fictional Marvel Universe, which in turn is part of a larger multiverse. Starting with the Captain Britain story in The Daredevils #7, the main continuity in which most Marvel storylines take place was designated Earth-616, and the Multiverse was established as being protected by Merlyn. Each universe has a Captain Britain designated to protect its version of the British Isles. These protectors are collectively known as the Captain Britain Corps. This numerical notation was continued in the series Excalibur and other titles. Each universe of the Multiverse in Marvel also appears to be defended by a Sorcerer Supreme at nearly all times, appointed by the mystic trinity of Vishanti to defend the world against threats primarily magical in nature from within and beyond and bearing the Eye of Agamotto.
Worldbuilding is the process of constructing an imaginary world or setting, sometimes associated with a fictional universe. Developing the world with coherent qualities such as a history, geography, culture and ecology is a key task for many science fiction or fantasy writers. Worldbuilding often involves the creation of geography, a backstory, flora, fauna, inhabitants, technology and often if writing speculative fiction, different peoples. This may include social customs as well as invented languages for the world.
Fictional locations are places that exist only in fiction and not in reality, such as the Negaverse or Planet X. Writers may create and describe such places to serve as a backdrop for their fictional works. Fictional locations are also created for use as settings in role-playing games such as Dungeons & Dragons.
Atlantis is a fictional location appearing in American comic books published by Marvel Comics. It is based on the mythical island of Atlantis first mentioned in Plato's initial dialogue the Timaeus, written c. 360 BC. In the Marvel Universe, Atlantis was a small continent with many human settlements. Over 21,000 years ago, an event called the "Great Cataclysm" caused it to be submerged into the sea.
Fantasy cartography, fictional map-making, or geofiction is a type of map design that visually presents an imaginary world or concept, or represents a real-world geography in a fantastic style. Fantasy cartography usually manifests from worldbuilding and often corresponds to narratives within the fantasy and science fiction genres. Stefan Ekman says, "a [regular] map re-presents what is already there; a fictional map is often primary – to create the map means, largely, to create the world of the map."
