In the revised origin, the Immortal Man is born roughly 50,000 years ago as Klarn, leader of the Bear Tribe. Klarn is a mortal enemy of Vandar Adg of the Wolf Clan, their two clans repeatedly fighting. During one battle, a radioactive meteorite crashes nearby. Exposure to it makes Vandar immortal and invulnerable to injury while evolving his mind. After Vandar leaves, Klarn frees a glowing jewel from the meteorite and fashions it into an amulet. His mind also evolves and he later realizes he now has a unique form of reincarnation. Throughout history, he fights to protect people from threats and repeatedly interferes with the schemes of Vandar Adg, who adopts the name Vandal Savage.
