Following the 'DC Rebirth relaunch event in 2016, the Immortal Man is reintroduced in the 2017 comic book "Dark Days: The Forge;" he is given a new supporting cast of agents and followers, the "Immortal Men" of the House of Action. Immortal Man and his new supporting cast then appear in the 2018 series "The Immortal Men," which explores them all further over the course of six issues. Now said to be one of five beings who make up the Council of Immortals, all of whom gain immortality after discovering a meteorite, Klarn's reincarnation ability and other powers are now gone, and he is simply ageless and invincible to injury like Vandal Savage. He can also share some of his immortality, making his Immortal Men agents in the House of Action ageless and immune to all disease, though he is unable to make them invulnerable. The House of Action wages a secret "Eternal War" not just against evil but specifically against Klarn's sister Kyra, the Infinite Woman, and her House of Conquest. The first issue of "The Immortal Men" introduces Caden Park, a seventeen-year-old boy with limited telepathy whom the Immortal Man hopes to use as a host body to escape death in battle. Instead, Caden inherits Klarn's resources and alias.
