This episode is very similar in some ways to the DC Comic series Justice League: A World without Grown-Ups which was the prelude to the creation of the series Young Justice staring Robin, Superboy and Impulse. In the story, a blond-haired boy comes into possession of an artifact that contains in it purple energy similar to Mordred. The boy wishes for a world without grown-ups. However, unlike this episode, the Justice League did not get transformed into children, but instead their sidekicks defeated the genie and his master. This story also shares elements to another Young Justice storyline, Sins of the Youth in which the Justice League is transformed into children, while the younger heroes are transformed into adults.
When John is turned into a kid, the mask he creates to replace his glasses is very similar to the mask that is worn by Kyle Rayner in the comics.
The octopus-headed statues in the ruins at the beginning bear a suspicious resemblance to Cthulhu, one of the Old Ones chronicled in the fictional writings of H.P. Lovecraft. A pastiche of the Cthulhu mythos exists in the DCAU as the Thanagarian Icthulhu religion in The Terror Beyond (2003) (Parts I/II).
Wonder Woman speaks and acts like a typical American child, rather than the way a girl brought up by Amazons would.
