Superman and Lois celebrate Lois's birthday in the sky, when suddenly a flying pyramid comes toward them. Inside the pyramid is Cybron, a hostile cyborg from the future. Superman takes the pyramid to a government facility. At the facility, Cybron attacks Lois and Jimmy, transforming them into cyborgs, as well as all the other goverment officials. Lois and Jimmy later discover the truth about Superman, when Lois stumbles on Clark changing into Superman. Superman takes them to STAR Labs, to turn them back to normal, and erasing their memories about him being Superman in the process. He then devises a way to defeat Cybron.
