Title: Krypton (comics)
Content:  Krypton is a fictional planet appearing in American comic books published by DC Comics. The planet is the native world of Superman and is named after the element Krypton. The planet was created by Jerry Siegel and Joe Shuster, and was first referred to in Action Comics #1 (June 1938). The planet made its first full appearance in Superman #1 (summer 1939). Krypton is also the native world of Supergirl, Krypto the Superdog, and Power Girl (in her case, an alternate-universe version designated "Krypton-Two"). It has been consistently described as having been destroyed shortly after Superman's escape from the planet, although the exact details of its destruction vary by time period and writers. Kryptonians were the dominant species on Krypton. Krypton also makes an appearance in the television series Adventures of Superman, Lois & Clark: The New Adventures of Superman, Smallville, Supergirl, and a TV series with same name. Krypton made its film debut in the 1978 film Superman, 2006 film, Superman Returns, and the 2013 film Man of Steel, set in the DC Extended Universe.
Title: Superman
Content:  In Action Comics #1 (1938), Superman is born on an alien world to a technologically advanced species that resembles humans. Shortly after he is born, his planet is destroyed in a natural cataclysm, but Superman's scientist father foresaw the calamity and saves his baby son by sending him to Earth in a small spaceship. The ship, sadly, is too small to carry anyone else, so Superman's parents stay behind and die. The earliest newspaper strips name the planet "Krypton", the baby "Kal-L", and his biological parents "Jor-L" and "Lora"; their names were changed to "Jor-el", and "Lara" in a 1942 spinoff novel by George Lowther. 
Title: Origin of Superman
Content:  While the individual details vary, certain key elements have remained consistent in almost all retellings. Superman is born Kal-El on the alien planet Krypton. His parents, Jor-El and Lara become aware of Krypton's impending destruction and Jor-El begins constructing a spacecraft to carry Kal-El to Earth. During Krypton's last moments, Jor-El places young Kal-El in the spacecraft and launches it. Jor-El and Lara die as the spacecraft barely escapes Krypton's fate. The explosion transforms planetary debris into kryptonite, a radioactive substance that is lethal to superpowered (via Earth's yellow sun) Kryptonians. The spacecraft lands in the rural United States, where it 
Title: Superman's Metropolis
Content: The city that Superman protects was actually named after the 1927 silent film Metropolis. ; In the original script for Metropolis, the name of the robot was Futura. The fact that the robot in the story is named Futura is an inside joke referring to the film. ; This universe was designated as a former part of the DC Multiverse called the universe of Earth-1927 in the hardcover book Absolute Crisis On Infinite Earths. ; There has been no report yet of Earth-1927 appearing as one of the 52 Earths in the new DC Multiverse. 
Title: Superman
Content:  Superman is a superhero who appears in American comic books published by DC Comics. The character was created by writer Jerry Siegel and artist Joe Shuster, and debuted in the comic book Action Comics #1 (cover-dated June 1938 and published April 18, 1938). Superman has been adapted to a number of other media which includes radio serials, novels, movies, television shows and theatre. Superman was born on the fictional planet Krypton and was named Kal-El. As a baby, his parents sent him to Earth in a small spaceship moments before Krypton was destroyed in a natural cataclysm. His ship landed in the American countryside, near the fictional town of Smallville. He was found and adopted by farmers Jonathan and Martha Kent, who named him Clark Kent. Clark developed various superhuman abilities, such as incredible strength and impervious skin. His

Content:  asking whether he wants to hide for the rest of his life, and his adoptive father coining the name "Superman". Clark decides to wear the outfit and reveals himself to the world as Superman. Superman lands and starts destroying the alien robots and ships, and Tyrell reveals himself. He proves to be Superman's physical match, and says that Krypton's destruction was no accident but was an assassination. Tyrell originates from the planet Dheron. Krypton and Dheron were bitter enemies that fought several wars, which ended when a man whose identity is not-yet revealed provided a war machine, designed to destroy Krypton's core. Although Krypton was destroyed, a 
Title: The Reign of the Superman
Content:  under the pen name Herbert S. Fine, combining the first name of a cousin with his mother's maiden name. The term "Superman" derives from a common English translation of the term Übermensch, which originated with Friedrich Nietzsche's statement, "Ich lehre euch den Übermenschen" ("I will teach you all the Superman"), in his 1883 work Thus Spoke Zarathustra. The term "Superman" was popularized by George Bernard Shaw with his 1903 play Man and Superman. The character Jane Porter refers to Tarzan as a "superman" in the 1912 pulp novel Tarzan of the Apes by Edgar Rice Burroughs, and Siegel would later name Tarzan as an influence on the creation of his and Shuster's Superman.
Title: Superfolks
Content:  The novel's protagonist is a Superman analogue named David Brinkley (a tuckerization of TV newsman David Brinkley). His superhero codename is never fully given: various intelligence agencies refer to him as "Indigo" (the color of his mask) and "der Übermensch" (Overman) and the original book jacket refers to him as "Everyman." He hails from the planet Cronk and is vulnerable to the substance Cronkite (a play on both TV newsman Walter Cronkite, and Superman's home Krypton and weakness to Kryptonite). David gradually loses his superhuman powers due to the influence of an unknown enemy, and all of the other superheroes (including, strangely, Snoopy) retire, disappear, or die. It is later revealed that this is a plot made by the alien elf Pxyzsyzygy (Mr. Mxyzptlk by way of Howard Hughes) to kill all heroes. David's powers gradually return, years later, in the 
Title: Rao (comics)
Content:  Rao is a fictional star in the DC Comics Universe. It is the red supergiant (in some continuities, red dwarf ) that the planet Krypton orbited. The title also refers to a supervillain of the same name and same Kryptonian etymology. He is also the ancestor of Superman in all continuities. "Rao" is also later written into the Superman mythology as the name of a Kryptonian deity, the personification of their sun, worshipped as a god of light and life. As such the name was sometimes invoked in the comics as a Kryptonian exclamation. For instance, 'By Rao, that curry is hot' or 'Thank Rao you're ok'.
Title: Superman
Content:  Some believe that Superman took inspiration from Judaic mythology. The British rabbi Simcha Weinstein notes that Superman's story has some parallels to that of Moses. For example, Moses as a baby was sent away by his parents in a reed basket to escape death and adopted by a foreign culture. Weinstein also posits that Superman's Kryptonian name, "Kal-El", resembles the Hebrew words קל-אל, which can be taken to mean "voice of God". The historian Larry Tye suggests that this "Voice of God" is an allusion to Moses' role as a prophet. The suffix "el", meaning "(of) God", is also found in the name of angels (e.g. Gabriel, Ariel), who are airborne humanoid agents of good with superhuman
