Ultra-Man (Gary Concord) is the name of two fictional comic-book superheroes, father and son, that first appeared during the 1940s, the period fans and historians call the Golden Age of comic books.

In All-American Comics #9 (Dec. 1939), the story continues with Gary Concord, Jr., who would appear until issue #19 in 1940.

[1] In summer 1940, Ultra-Man was included in the first issue of All Star Comics, however he made no further appearances in that title.

Gary Concord Sr., a 20th-century scientist, had devoted his life to finding the means to end war.

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.
