American comic books in the context of "Jimmy Olsen"

A superhero or superheroine, is a character who typically possesses superpowers or abilities beyond those of ordinary people, is frequently costumed concealing their identity, and fits the role of the hero, typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime. Superhero fiction is the genre of fiction that is centered on such characters, especially, since the 1930s, in American comic books (and later in Hollywood films, film serials, television and video games), as well as in Japanese media (including kamishibai, tokusatsu, manga, anime and video games).

Superheroes come from a wide array of different backgrounds and origins. Most superheroes (for example, Superman and Spider-Man) usually possess non-human or superhuman biology, while others (such as Batman and Iron Man) derive their status from advanced technology they create and use, but some of them may use or possess objects that have superhuman, mystical, or alien powers (such as Green Lantern and He-Man), or study and practice magic to achieve their abilities (such as Doctor Fate and Doctor Strange). The Dictionary.com definition of "superhero" is "a figure, especially in a comic strip or cartoon, endowed with superhuman powers and usually portrayed as fighting evil or crime," and the Merriam-Webster dictionary gives the definition as "a fictional hero having extraordinary or superhuman powers; also: an exceptionally skillful or successful person." Terms such as masked crime fighters, costumed adventurers or masked vigilantes are sometimes used to refer to characters such as the Spirit, who may not be explicitly referred to as superheroes but nevertheless share similar traits.

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.

Krypton is a fictional planet appearing in American comic books published by DC Comics, most commonly appearing or mentioned in stories starring the superhero Superman as the world from which he came. The planet was created by Jerry Siegel and Joe Shuster, and was named after the chemical element krypton. It was first mentioned in Action Comics #1 (June 1938) and made its first appearance in Superman #1 (June 1939). Krypton is destroyed immediately after Superman, as the baby Kal-El, is sent from the planet in a spacecraft by his parents, although the exact details of its destruction have varied over publication history.

The planet is portrayed as having been far more technologically advanced than Earth, and having orbited a red sun. Kryptonians were the dominant species on Krypton, and its inhabitants included Kara Zor-El, Krypto, Beppo, Kara Zor-L (in her case, an alternate-universe version designated "Krypton-Two"), and the supervillain General Zod.

Smallville is a fictional town in American comic books published by DC Comics. The childhood hometown of Superman, Smallville was first named in Superboy #2 (May 1949). The town, long in an unnamed US state that was first defined as Kansas in Superman: The Movie (1978), is the setting of many Superboy comics where Superboy defends Smallville from various threats. Since the 1978 appearance in Superman: The Movie, Smallville has been a setting in other non-comic book productions (film, television, video games and novels) featuring Superboy / Superman.

Jonathan Kent and Martha Kent (often referred to as "Pa" and "Ma" Kent, respectively) are fictional characters in American comic books published by DC Comics. They are the adoptive parents of Superman, and live in the rural town of Smallville, Kansas. In most versions of Superman's origin story, Jonathan and Martha find Kal-El as an infant after he crash-lands on Earth following the destruction of his home planet, Krypton. They adopt him shortly thereafter, renaming him Clark Kent, "Clark" being Martha's maiden name.

The Kents are usually portrayed as loving parents who instill within Clark a strong moral compass, and they encourage Clark to use his powers for the betterment of humanity. In some continuities, Martha is also the one who creates Clark's superhero costume, often from the baby blankets Clark's biological parents had swaddled him in before enclosing him in the capsule, which are found to withstand virtually all hazards.

Lois Lane is a fictional character appearing in American comic books published by DC Comics. Created by writer Jerry Siegel and artist Joe Shuster, she first appeared in Action Comics #1 (June 1938). Lois is an award-winning journalist for the Metropolis newspaper the Daily Planet and the primary love interest of the superhero Superman and his alter ego, Clark Kent. In DC continuity, she is also his wife and the mother of their son, Jon Kent, the newest Superboy in the DC Universe.

Lois's physical appearance was originally based on Joanne Carter, a model hired by Joe Shuster. Jerry Siegel took her name from actress Lola Lane, while her character was inspired by actress Glenda Farrell's portrayal of the fictional reporter Torchy Blane in a series of 1930s self-titled films.

Alexander Joseph "Lex" Luthor (/ˈluːθɔːr, -θər/) is a supervillain appearing in American comic books published by DC Comics. Created by writer Jerry Siegel and artist Joe Shuster, the character first appeared in Action Comics #23 (April 1940). He has since endured as the archenemy of Superman. While Superman embodies hope and selflessness, Luthor symbolizes unrestrained ambition and humanity’s belief in the superiority of intellect over superhuman power.

Unlike many supervillains, Luthor is an ordinary human with no superpowers or secret identity. His true strength lies in his unparalleled intelligence, vast wealth, and influence over politics, science, and technology. A genius with an extraordinary aptitude for business and manipulation, he is also proud, calculating, pragmatic, and vengeful—driven by an insatiable thirst for control and devoid of ethical principles. Luthor does not envy superheroes for their abilities but rather for the adoration they receive. He believes that the admiration society bestows upon them is recognition that rightfully belongs to him. Convinced that he alone possesses the intellect and capability to lead humanity, he justifies his ambition with the belief that only he is fit to guide the world. Luthor sees Superman as a threat, seeking to eliminate him not only out of personal rivalry but also because he believes the existence of an all-powerful being fosters dependence, preventing humanity from achieving its full potential.

Dr. Thomas Wayne, M.D. is a fictional character appearing in American comic books published by DC Comics. He is the father of Bruce Wayne (Batman), and husband of Martha Wayne as well as the paternal grandfather of Damian Wayne. Wayne was introduced in Detective Comics #33 (November 1939), the first exposition of Batman's origin story. A gifted surgeon and philanthropist to Gotham City, Wayne inherited the Wayne family fortune after Patrick Wayne. When Wayne and his wife are murdered in a street mugging, Bruce is inspired to fight crime in Gotham as the vigilante Batman.

Wayne was revived in Geoff Johns' alternate timeline comic Flashpoint (2011), in which he plays a major role as a hardened, more violent version of Batman, whose son was killed instead of his wife and himself, leading both of them to become the altered reality's counterparts of Batman and the Joker respectively, and dies again by the end of the storyline. Dr. Wayne returned to the main DC Universe in DC Rebirth, as a revived amalgamation of his original self killed by Joe Chill and his Flashpoint Batman self killed in "The Button", teaming up with the supervillain Bane to attempt to force his son to retire as Batman.
