While one does not usually associate Jack Kirby with DC Comics, the "King" did do many features for DC, and even got the chance to draw an early cover for Detective Comics, Detective Comics #65 (July, 1942....which was also worked on by Joe Simon and Jerry Robinson, likely Kirby/Simon on the Boy Commandos and Robinson on Batman/Robin) as Batman and Robin welcomed the new creations to Detective Comics.

The Boy Commandos were revived for 2 issues of reprints in 1973, as well as a Super Spectacular, after having a few tales reprinted in the 1970s Mr. Miracle series, as well (which included reprints of the tales of their meetings with Sandman and the Newsboy Legion).

Orion of the New Gods, and the other original lads as well as Rip had a reunion in the Millennium crossover issue of Blue Beetle (which also featured Mr. Miracle and the Manhunters).
