Many of the stories in season one involved normal human criminals using advanced and powerful technology or involved in large and dangerous conspiracies—most, if not all, of the Lex Luthor stories of season one. After season one, series creator Deborah Joy LeVine left the show as a producer, and a new production team took over the series. Episode plots gradually shifted from those in which Lois, Clark, and Superman only became involved with criminal elements or dangerous situations through their own initiative to more fantastic plots. The show often centered on comic-style villains who specifically targeted Lois, Superman, or Clark from the beginning, rather than endangering the protagonists as a reactionary measure when they became threats to other criminal plans. Later plots frequently revolved around villains with special superhuman powers and abilities.
