Published by DC Comics in Action Comics #1 (June 1938), Superman is a superhero and alien named Kal-El from the destroyed planet Krypton. He was sent to Earth and raised as Clark Kent by human foster parents, Martha and Jonathan Kent. Kal-el’s powers were dormant until his teenage years. His Kryptonian physiology absorbs immense energy from Earth’s yellow sun, enabling him to fly at incredible speeds and giving him with his super powers and abilities.
As an adult and growing up as Clark Kent, he devoted his life to helping others with the abilities he developed from Earth’s sun. Moving to Metropolis, he became Superman, while still maintaining his secret identity as Clark Kent, working at the Daily Planet as a Reporter/Journalist.
Though Superman’s origins have been altered a few times because of temporal events that change history, the rest of his life seems largely consistent. Superman’s biography details within the continuity from the “Pre-Crisis” (1938-1985); following the reboot that took place in Crisis on Infinite Earths or “Post-Crisis” (1986-2011); then another reboot into the New 52 (2011-2016), after the Flashpoint crossover timeline.
Although the continuity of The New 52 continued, its branding ended in May 2015 after the completion of the “Convergence” storyline. In February 2016, DC announced their Rebirth initiative with the release of an 80-page one-shot on May 25, 2016, and continuing through late 2016 to the present.
