Superman - Comic book character

Superman, given the serial nature of comic publishing and the length of the character's existence, has evolved as a character as his adventures have increased. The details of Superman's origin, relationships and abilities changed significantly during the course of the character's publication, from what is considered the Golden Age of Comic Books through the Modern Age. The powers and villains were developed through the 1940s, with Superman developing the ability to fly, and costumed villains introduced from 1941. The character was shown as learning of the existence of Krypton in 1949. The concept itself had originally been established to the reader in 1939, in the Superman comic strip.

The 1960s saw the introduction of a second Superman. DC had established a multiverse within the fictional universe its characters shared. This allowed characters published in the 1940s to exist alongside updated counterparts published in the 1960s. This was explained to the reader through the notion that the two groups of characters inhabited parallel Earths. The second Superman was introduced to explain to the reader Superman's membership of both the 1940s superhero team the Justice Society of America and the 1960s superhero team the Justice League of America.

The 1980s saw radical revisions of the character. DC decided to remove the multiverse in a bid to simplify its comics line. This led to the rewriting of the back story of the characters DC published, Superman included. John Byrne rewrote Superman, removing many established conventions and characters from continuity, including Superboy and Supergirl. Byrne also re-established Superman's adoptive parents, The Kents, as characters. In the previous continuity the characters had been written as having died early in Superman's life (about the time of Clark Kent's graduation from high school).

The 1990s saw Superman killed by the villain Doomsday, although the character was soon resurrected. Superman also marries Lois Lane in 1996. His origin is again revisited in 2004. In 2006 Superman is stripped of his powers, although these are restored within a fictional year.
