He is a founding member of the Justice League of America and a charter member of the Legion of Super-Heroes in the 30th Century.Superman's origin story has been rewritten and rebooted many times over the years; most notably in John Byrne's 1986 The Man of Steel, Mark Waid's 2003 Superman: Birthright, Geoff Johns' 2009 Superman: Secret Origin and Grant Morrison's 2011 Action Comics.Jor-El explained that exposure to the yellow sunlight would charge Kal-El cells into living solar batteries and gift him with incredible powers.Just before Krypton finally came to an end his parents sent him to Earth as they planned.He operated this way for seven years until he was forced to save a space-plane in front of crowds of people, then meeting reporter Lois Lane for the first time at age 25.Deciding that it was time for him to become a public figure, Clark and Jonathan designed a symbol for him to wear while Martha created a costume.Lois Lane (wife), Jonathan Samuel Kent (son), Jor-El (birth father, deceased), Lara Lor-Van (birth mother, deceased), Jonathan Kent (adoptive father, deceased), Martha Kent (adoptive mother), Kara Zor-El (aka Supergirl, cousin), Kon-El/Conner Kent (aka Superboy, partial clone/adoptive brother), Christopher Kent (aka Nightwing, foster son), Kem-L (ancestor, deceased), Rao (ancestor), See House of El and Kent Family for extended family line Justice League, Superman Family, Daily Planet · formerly Justice League of America, Legion of Super-Heroes, Kryptonian Military Guild, Supermen of America, Supermen of the Multiverse, Black Lantern Corps, White Lantern Corps It is a remarkable dichotomy.
