Music and Imagery
This episode contained several visual references to the old Max Fleischer Superman cartoons from the 1940's. The first one was Superman's battle with several robots which resembled those from the 1941 animated feature "The Mechanical Monsters" in both appearance and the manner in which they "gang up" on Superman. The second was when Brainiac attacked Superman with a laser blast, which Superman repelled by punching. In the debut animated feature "Superman" Superman also illogically repelled a mad scientist's laser blast by punching at it.
