In subsequent appearances in this early period, Brainiac was used mostly as a plot device rather than as a featured villain of the month. Brainiac's next appearance was mostly behind the scenes, when he tried to kill Lois Lane and Lana Lang, prompting Superman to give Lois and Lana superpowers. But the villain remained unseen except as a plot twist at the end of the story. Brainiac's next appearance was in "Superman's Return to Krypton" in "Superman" #141 (November 1960), in which the villain stole the bottle city of Kandor, the only city on Krypton that believes Jor-El's warning of doom for the planet, and which had already built a space ark within the city to save the population. Brainiac's next present-day appearance was in "Action Comics" #275 (April 1961), which showed the villain planning to defeat Superman by exposing him to red-green kryptonite, which he had created, giving Superman a third eye on the back of his head, forcing him to wear various hats to hide it. Superman soon defeated Brainiac and sent him off into the distant past. This was the first in-story appearance of Brainiac's iconic red diode/electrode-like objects atop his head, which had previously appeared on the cover of his first appearance in "Action Comics" #242 (July 1958), but were not shown in the actual story. In "Superboy" #106 (July 1963), an infant Superman meets Brainiac, and it is explained that Brainiac looks the same due to his 200-year life span. In "Superman" #93, Brainiac regenerates himself. It is revealed that he came from a planet called Bryak and, after a voyage in space, he returned to find everybody dead from a plague. He intended to get people from other planets (in shrunken cities to be enlarged with his growth ray) to repopulate Bryak, where he would rule them.
