Earth-Man is Kirt Niedrigh, a super-powered figure in the 30th Century who has been both hero and villain. His power allows him to absorb the power of others. He took the name Earth-Man when he became leader of the xenophobic Justice League of Earth, a group dedicated to killing aliens. He was later selected for membership in the Green Lantern Corps, where he became a hero and joined the Legion of Super-Heroes. The Earth-Man identity was created by Geoff Johns and Gary Frank, first appearing in Action Comics #859. (2008)
