Ultra-Man

Gary Concord, the Ultra-Man was the name of two fictional, comic-book superheroes, father and son, who first appeared during the 1940s, the period fans and historians call the Golden Age of comic books. Both were characters of All-American Publications, which merged, in 1946, with DC Comics-predecessor National Periodical Publications.

They are separate from the DC Universe character Ultraman, a supervillain and evil counterpart of Superman, who was introduced in Justice League of America #29 (cover-dated Aug. 1964) or the Japanese superhero Ultraman.
