Following the "DC Rebirth" 2016 relaunch of DC Comics, a new version of Immortal Man is introduced in the series "Immortal Men". In the new history, Klarn Arg is born in the 47th century BCE, a member of the Bear Clan with siblings. One night, a radioactive meteorite strikes Earth and the four siblings investigate alongside Vandar Adg and the Wolf Clan. The five primitive humans are bathed in strange radiation that evolves their minds and makes them immortal. The five form a Council of Immortals and decide to help humanity but debate the best method to do so. Three methods debated are through knowledge, through harmony, or through expression. Klarn, who eventually takes the name Immortal Man, believes in saving humanity through action, specifically "the action of good people striving to save others." His sister Kyra, who adopts the name Infinite Woman, argues humanity rises best through conquest or when forced to face an enemy.
