Mad scientist in the context of "Motif (narrative)"

The damsel in distress is a narrative device in which one or more men must rescue a woman who has been kidnapped or placed in other peril. The "damsel" is often portrayed as beautiful, popular, and of high social status; she is usually depicted as a princess in works with fantasy or fairy tale settings. Kinship, love, lust or a combination of those motivate the male protagonist to initiate the narrative, and potentially become a hero of valour.

Critics have linked the helplessness of these women to societal views that women as a group need to be taken care of by men and treated nicely. Throughout the history of the trope, the role of the woman as the victim in need of a male savior has remained constant, but her attackers have changed to suit the tastes and collective fears of the period: "monsters, mad scientists, Nazis, hippies, bikers, aliens..."

The Spirit is a fictional masked crimefighter appearing in American comic books. Created by cartoonist Will Eisner, he first appeared as the main feature of a tabloid-sized comic book insert distributed in the Sunday edition of Register and Tribune Syndicate newspapers. Popularly referred to as "The Spirit Section", the insert ran from June 2, 1940 to October 5, 1952.

The Spirit is the alias of Denny Colt, a private investigator and criminologist based in the fictional Central City, who falls into suspended animation while trying to apprehend the mad scientist Dr. Cobra. Officially pronounced dead, Colt revives after being interred in Wildwood Cemetery. With the blessing of his old friend, police Commissioner Eustace Dolan, Colt becomes a domino mask-wearing "friendly outlaw" who pursues criminals that might otherwise escape capture by traditional law enforcement. The Spirit usually does not possess any superpowers, but relies on his wits and physical prowess, as well as the myth of his supposed resurrection, in his battles against evildoers. He frequently encounters femme fatales over the course of his adventures, including serial seducer P'Gell, thief-turned-troubleshooter Silk Satin, and his estranged childhood friend Sand Saref; he also comes into conflict with his archenemy the Octopus, an unseen criminal mastermind. Other supporting characters include Ellen Dolan, Commissioner Dolan's headstrong daughter and the Spirit's primary love interest, and his recurring sidekick Ebony White, a young, diminutive cab driver.

In philosophy, the brain in a vat (BIV) is a scenario used in a variety of thought experiments intended to draw out certain features of human conceptions of knowledge, reality, truth, mind, consciousness, and meaning. Gilbert Harman conceived the scenario, which Hilary Putnam turned into a modernized version of René Descartes's evil demon thought experiment. Following many science fiction stories, the scenario involves a mad scientist who might remove a person's brain from the body, suspend it in a vat of life-sustaining liquid, and connect its neurons by wires to a supercomputer that would provide it with electrical impulses identical to those a brain normally receives. According to such stories, the computer would then be simulating reality (including appropriate responses to the brain's own output) and the "disembodied" brain would continue to have perfectly normal conscious experiences, like those of a person with an embodied brain, without these being related to objects or events in the real world. According to Putnam, the thought of "being a brain-in-a-vat" is either false or meaningless.

Considered a cornerstone of semantic externalism, the argument produced significant literature. The Matrix franchise and other fictional works (below) are considered inspired by Putnam's argument.

Doctor Octopus (Dr. Otto Octavius), also known as Doc Ock for short, is a fictional character appearing in American comic books published by Marvel Comics. The character was created by Stan Lee and Steve Ditko and first appeared in The Amazing Spider-Man #3 (July 1963). He is a highly intelligent, myopic, and stocky mad scientist who sports four strong and durable appendages resembling an octopus's tentacles, which extend from his body and can be used for various purposes. After his mechanical harness became permanently fused to his body during a laboratory accident, he turned to a life of crime, and came into conflict with the superhero Spider-Man. He has endured as one of Spider-Man's most prominent villains, and is regarded as one of his three archenemies, alongside the Green Goblin and Venom. He is the founder and leader of the Sinister Six, the first supervillain team to oppose Spider-Man.

While usually portrayed as a supervillain, Doctor Octopus has also been occasionally depicted as a conflicted antihero and ally of Spider-Man. Following Spider-Man's death in the 2012 storyline "Dying Wish", which saw a dying Octavius swapping bodies with the hero and letting him die in his original body, Octavius was motivated to prove he could be a better Spider-Man. As such, he adopted the Superior Spider-Man alias, introduced in Avenging Spider-Man #15.1 following a cameo in Daredevil vol. 3 #21 (both December 2012), as the fourth predominant main continuity Spider-Man. The Superior Spider-Man possesses all of the original Spider-Man's abilities, memories, and equipment, along with additional gadgets created by Octavius, though he often struggles to live up to his predecessor's legacy and seeks to turn his life around after being a villain for years.

The Man of Steel is a 1986 comic book limited series featuring the DC Comics character Superman. Written and drawn by John Byrne, the series was presented in six issues which were inked by Dick Giordano. The series told the story of Superman's modern origin, which had been rebooted following the 1985–1986 series Crisis on Infinite Earths.

DC editors wanted to make changes to the character of Superman, including making him the sole survivor of his home planet Krypton, and Byrne's story was written to show these changes and to present Superman's origin. The series includes the embryonic Kal-El rocketing away from the destruction of Krypton and his birth upon landing in Kansas when he emerged from the artificial womb, Clark Kent as a teenager in Smallville learning that he was found in a crashed space ship, him being hired at the Daily Planet in Metropolis, the creation of his secret identity of Superman, his first meeting with fellow hero Batman, and how he finally learned of his birth parents and from where he came. The series also included the reintroduction of a number of supporting characters, including fellow reporter and love interest Lois Lane and archenemy Lex Luthor, who was re-branded from a mad scientist to a powerful businessman and a white-collar criminal.

Doctor Sivana is the name of two fictional, related characters appearing in American comic books published by DC Comics. The original Doctor Sivana's alter-ego is Thaddeus Bodog Sivana, a recurring enemy of the superhero Captain Marvel created by Bill Parker and C. C. Beck and first appeared in Whiz Comics #2 (cover-dated February 1940) by Fawcett Comics. A mad scientist and inventor bent on world domination, the character was established as Captain Marvel's main archenemy during the Golden Age, appearing in over half of the Fawcett Captain Marvel stories published between 1939 and 1953. Thaddeus has kept his role as one of the key archenemies of Captain Marvel (now Shazam) throughout the character's appearances in DC Comics, which eventually acquired the rights to Fawcett's superhero characters. In 2009, Doctor Sivana was ranked as IGN's 82nd-greatest comic book villain of all time.

The second character known as Doctor Sivana is Georgia Sivana, P.h.D, the daughter of Thaddeus who first appeared in Mary Marvel #1, created by Otto Binder. Georgia was originally portrayed as an underling of her father who takes after her father in appearance and skills, both possessing keen scientific minds although the character is instead an arch-nemesis for Mary Marvel. Years following "The New 52" reboot and during the "Infinite Frontier" initiative, Georgia's character is revamped into an older professor, archaeologist, and estranged daughter of Thaddeus whose reputation is tarnished due to her father's obsession with magic in the scientific community and seeks to improve it at any cost.

Crash Bandicoot is a video game franchise created by Naughty Dog as a flagship title for Sony's PlayStation console. The series began with the development of the first game in 1994, inspired by the emerging capabilities of 3D consoles and games like Donkey Kong Country (1994). The protagonist, initially conceived as "Willy the Wombat", evolved into Crash Bandicoot, a goofy, genetically mutated eastern barred bandicoot who escapes the clutches of the mad scientist Doctor Neo Cortex. The original trilogy—completed by Cortex Strikes Back (1997) and Warped (1998)—along with the kart racing game Crash Team Racing (1999), received critical praise for their vibrant visuals and polished gameplay. After Naughty Dog's departure following Crash Team Racing due to creative exhaustion and ownership issues, the franchise transitioned from Sony exclusivity to multiplatform releases under multiple developers and publishers, including Universal Interactive, Vivendi Games, and eventually Activision.

Gameplay centers on 3D platforming with a linear or hub-based level progression. Players control Crash through linear, obstacle-filled levels viewed primarily from a third-person perspective, with occasional shifts to a side-scrolling perspective and levels in which Crash flees a pursuing hazard by running toward the screen. Core mechanics include jumping, spinning to defeat enemies, and collecting Wumpa fruit for extra lives, alongside breaking crates for bonuses and gathering crystals, gems, and relics to unlock content. Later entries introduce abilities granted by defeating bosses. Set in a fictional archipelago with diverse biomes, and including time-traveling and multiversal elements in later games, the series features a cast including Crash, his sister Coco, allies like the protective spirit Aku Aku, and villains including Cortex, Uka Uka, and various mutant henchmen.
