After Gary Sr. dies of natural causes in 2239, Gary Jr. succeeds him as both Ultra-Man and as High Moderator of the United States of North America, the country's chief executive. He battles the warlord Tor and other menaces, and is later put into suspended animation until the 100th century. An encounter with the superheroine XS (Jenni Ognats) of the Legion of Super-Heroes inspires Ultra-Man to form his own such team with fellow heroes Avatar, Behemoth, and Metallica on the planet Almeer-5.
