Batman in the context of "DC Comics"

A hero (feminine: heroine) is a real person or fictional character who, in the face of danger, combats adversity through feats of ingenuity, courage, or strength. The original hero type of classical epics did such things for the sake of glory and honor. Post-classical and modern heroes, on the other hand, perform great deeds or selfless acts for the common good instead of the classical goal of wealth, pride, and fame. The antonym of hero is villain. Other terms associated with the concept of hero may include good guy or white hat.

In classical literature, the hero is the main or revered character in heroic epic poetry celebrated through ancient legends of a people, often striving for military conquest and living by a continually flawed personal honor code. The definition of a hero has changed throughout time. Merriam Webster dictionary defines a hero as "a person who is admired for great or brave acts or fine qualities". Examples of heroes range from mythological figures, such as Gilgamesh and Iphigenia, to historical and modern figures, such as Joan of Arc, Giuseppe Garibaldi, Sophie Scholl, Alvin York, Audie Murphy, and Chuck Yeager, and fictional "superheroes", including Superman and Batman.

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.

Robert Kane (né Kahn /kɑːn/; October 24, 1915 – November 3, 1998) was an American comic book writer, animator, and artist who created Batman and many other early related characters for DC Comics. He was inducted into the comic book industry's Jack Kirby Hall of Fame in 1993 and into the Will Eisner Comic Book Hall of Fame in 1996.

Milton "Bill" Finger (February 8, 1914 – c. January 18, 1974) was an American comic book writer who significantly contributed to the DC Comics character Batman with his creator, Bob Kane. Despite making major (sometimes, signature) contributions as an innovative writer, visionary mythos/world builder and illustration architect, Finger (like other creators of his era) was often relegated to ghostwriter status on many comics—including those featuring Batman, and the original Green Lantern, Alan Scott.

While Kane privately admitted in a 1980s audio interview with his autobiographer that Finger was responsible for "50–75% of all the creativity in Batman," he publicly denied Finger had been anything more than a subcontractor executing Kane's ideas for decades. As a result, Finger died in obscurity and poverty while the Batman brand, and Kane, amassed international fame and wealth. In the 2000s, Finger biographer Marc Tyler Nobleman's research uncovered previously unknown heirs. At the urging of Nobleman, the online comics fan community, and others, Finger's granddaughter revived the fight to restore his lost legacy, which continued for years. In 2015, DC Comics's parent company conditionally agreed to recognize Finger's intellectual property claim as co-creator of the Batman characters and mythos, officially adding his name, going forward, to the "created by" credit line Kane had been contractually guaranteed in 1939.

Detective Comics #27 is an American comic book of the Detective Comics anthology series known for debuting the superhero Batman in a featured story called "The Case of the Chemical Syndicate" during the Golden Age of Comic Books.

In addition to the debut of Batman, Detective Comics #27 included several other stories featuring established and original characters.
