Invisibility in fiction
Invisibility in fiction is a common plot device in stories, plays, films, animated works, video games, and other media, found in both the fantasy and science fiction genres. In fantasy, invisibility is often invoked and dismissed at will by a person, with a magic spell or potion, or a cloak, ring or other object. Alternatively, invisibility may be conferred on an unsuspecting person by a sorcerer, witch, or curse. In science fiction, invisibility is often conferred on the recipient as part of a complex technological or scientific process that is difficult or impossible to reverse, so that switching back and forth at frequent intervals is less likely to be depicted in science fiction. Depending on whether the science fiction is hard science fiction or soft science fiction, the depictions of invisibility may be more rooted in actual or plausible technologies (such as depictions of technologies to make a vessel not appear on detection equipment), or more on the fictional or speculative end of the spectrum.

Processes

Invisibility can be achieved by any number of different mechanisms, including perfect transparency without refraction, mechanisms that reroute light particles so that the subject is not apparent to viewers, and mind control techniques that cause the viewer's minds to simply edit out the subject. In the case of magic, often no attempt at explaining the mechanism is even used. In addition, there are many instances of imperfect invisibility such as cloaking devices in science fiction or the near-invisibility of fantastical creatures that are "out of phase" with this reality. In paranormal fiction, there can also be partial invisibility in that some people, such as psychics, may see invisible creatures or objects while others do not.

Special effects
Strictly speaking, invisibility does not show up and so itself is not the subject of any special effects techniques, but the interaction of invisible subjects with the visible world does call for special effects, especially in the case of invisible people wearing visible clothing. Early films and television shows used wires and puppetry to simulate the existence of an invisible person, along with some scenes that used a matte process to delete certain elements in favor of the background. In The Invisible Man the initial shots swathed the actor's head in a black velvet hood and shot this against a black velvet background. Later, CGI techniques and green screens allowed for greater variety, such as showing rain drops on invisible man Chevy Chase in Memoirs of an Invisible Man.

Historical examples

One of the first known fictional depictions of Invisibility is the Ring of Gyges described by Plato. According to the legend, Gyges of Lydia was a shepherd in the service of King Candaules of Lydia. After an earthquake, a cave was revealed in a mountainside where Gyges was feeding his flock. Entering the cave, Gyges discovered that it was in fact a tomb with a bronze horse containing a corpse, larger than that of a man, who wore a golden ring, which Gyges pocketed. He discovered that the ring gave him the power to become invisible by adjusting it. Gyges then arranged to be chosen as one of the messengers who reported to the king as to the status of the flocks. Arriving at the palace, Gyges used his new power of invisibility to seduce the queen, and with her help he murdered the king, and became king of Lydia himself. King Croesus, famous for his wealth, was Gyges' descendant.
 In the Buddhist tradition, Maudgalyayana - one of the Sakyamuni Buddha's closest disciples - was credited with having the power to make himself invisible, and using this power to save himself from murderous robbers.  
A Cloak of invisibility appears in such a Fairy tales as The Twelve Dancing Princesses. A more common trope is the cap of invisibility. The cap of invisibility has appeared in Greek myth: Hades was ascribed possession of a cap or helmet that made the wearer invisible. In some versions of the Perseus myth, Perseus borrows this cap from the goddess Athena and uses it to sneak up on the sleeping Medusa when he kills her. The thief Autolycus, grandfather of Odysseus, had a helmet to make him invisible. A similar helmet, the Tarnhelm, is found in Norse mythology - from which it was taken into Richard Wagner's Der Ring des Nibelungen where it is used by Alberich in Das Rheingold. In the Second Branch of the Mabinogi, one of the important texts of Welsh mythology, Caswallawn (the historical Cassivellaunus) murders Caradog ap Bran and other chieftains left in charge of Britain while wearing a cloak of invisibility.
 The 14th Century Sir Launfal is provided by his fairy lover Tryamour  with an invisible servant called Gyfre. Launfal then defeats the giant Valentyne, thanks to this invisible servant, who picks up his helmet and shield when Valentyne knocks them down.
After gaining magical power through his pact with the Devil, Doctor Faustus - as depicted in Christopher Marlowe's play - travels to Rome. Armed with his new powers and attended by Mephastophilis, he goes to the Pope's court, makes himself invisible, and plays a series of tricks. He disrupts the Pope's banquet by stealing food and boxing the Pope's ears .
According to legend the seventh century St. Aidan protected a stag from a pack of hunting dogs by miraculously turning it invisible.

Superhero fiction
The supernatural ability to turn invisible has become a popular superpower in superhero media, one of the most notable users being Marvel Comics' Invisible Woman, a member of the Fantastic Four. 

The power of invisibility is occasionally linked to the ability to create force fields, as seen with Invisible Woman and Disney Pixar's Violet Parr.

Films
The power to become invisible through scientific methods appeared in 1900s cinema. These films were influenced in some degree by H.G. Wells novel The Invisible Man (1897). The earliest known film featuring an invisible man is Sherlock Holmes Baffled (1900). Other early examples includes Les Invisibles (1906) in which a scientist creates a concoction which makes whoever who drinks it disappear from view. Other early examples include Le voleur invisible (1909) and The Invisible Wrestler (1911). The 1908 film The Invisible Fluid by Biograph Company features a scientist who creates a fluid that a young boy takes to help steal a cash register and invade police. There are other silent films with invisible men characters derived from Wells' novel rather than fantasy-oriented narratives. The concept of invisibility has been seen in non-science fiction films usually as a temporary element, such as cloaks of invisibility in films like Fritz Lang's Die Nibelungen (1924).

Universal Pictures made the novel into a film series in the early 1930s. Universal would also explore invisibility in three of their film serials: The Vanishing Shadow (1934), Flash Gordon (1936), and The Phantom Creeps (1939). In the late 1930s, Universal began making sequels to their horror films along with Joe May's The Invisible Man Returns (1940). Film critic Kim Newman described that Universal's later Invisible Man films setting how the next Invisible Man films were going to play out with characters becoming invisible through a scientific formula, all while other plot elements happen such as crime-oriented stories or spy stories. The series also added a key plot element to the majority of later "invisible man" themed films that being invisible drives the invisible person insane. This is seen in later films such as The Invisible Man Appears (1949), The Invisible Maniac (1990) and Hollow Man (2000).

Universal had made several remakes of their older horror film properties with the remake of The Mummy (1999) and The Wolfman (2010) and after the financial failure of The Mummy (2017), they had licensed their properties to the independent company Blumhouse Productions for The Invisible Man (2020). The film was released to positive reception from critics.

In The Elder Scrolls IV: Oblivion, a player can enchant multiple objects with a percentage of invisibility which creates 100% invisibility when worn. When combined with 100% stealth, this renders the player completely unable to be seen or heard by enemies. Enchanted invisibility is distinctly different from chameleon which only allows limited camouflage.

Miscellaneous
Dungeons & Dragons and many other role-playing games use several methods of invisibility, including magic potions, spells or devices.

Metaphorical use of the concept
 As detailed in disambiguation page "The Invisible Man", this has been the title of numerous works. Some of them deal with the fictional depiction of literal invisibility, while others use the title metaphorically in reference to members of discriminated or marginalized groups in society.
 Fictional depictions of the phenomena of "invisible women" due ageism and a societal focus on youth culture show women becoming socially "invisible" after a certain age  (e.g., older than the late 40s or the 50s). In some novels and short stories, women at or beyond these age categories may get less invitations to social activities, dates, and events. In Whitney Otto’s novel Now You See Her, an older woman who works in an office becomes more and more "invisible" to her coworkers.
